Pregnancy intentions, maternal behaviors, and infant health: investigating relationships with new measures and propensity score analysis

Inequitable Screening for Pregnancy Intention by Race, Insurance, and Site of Care in Two High-Volume Urban Obstetric Hospitals

Background: In the United States, public health efforts are focused on reducing unintended pregnancy. Yet, differences in rates of unintended pregnancy, abortion, and unintended births by race are driven by a combination of patient-, health system-, and provider-related factors. Despite this complicated scaffolding underpinning pregnancy intention, patients are often screened for pregnancy intention or planning when they have a positive pregnancy test. We hypothesized screening may vary by patient and health system characteristics. Objective: To identify associations between patient and health system characteristics and receiving screening for pregnancy intention or planning. Study Design: We performed a secondary analysis of a retrospective cohort study of all singleton deliveries in 2019 at two Philadelphia hospitals. Our primary outcome was the presence or absence of pregnancy intention screening by the clinical team. We used logistic regression to determine patient and hospital characteristics associated with screening for pregnancy intention. Results: We identified 9,672 deliveries, 48% of births were among Black individuals, 91% were non-Hispanic, and 45% had public or no insurance; of all births, 33% were screened for pregnancy intention or planning. Patients were more likely to be asked if their pregnancy was intended if they were: Black (2.38 [2.10-2.750]) or publicly insured or uninsured (2.78 [2.43-3.20]). The hospital site where the patient received care was the primary driver of whether a patient was asked about pregnancy intention (10.59 [9.35-12.0]). After accounting for the hospital sites, patients of Black race remained significantly more likely to be screened than White patients. Conclusions: Inequities in pregnancy intention or planning screening were driven by differences in institutional practices and patient race. These findings underscore the need for equitable screening practices that ensure all patients receive high-quality, unbiased, and patient-centered reproductive care.

The relationship between the timing of pregnancy discovery and prenatal attachment and distress: a case-control study

OBJECTIVE

This research was conducted to determine the relationship between the timing of pregnancy discovery and prenatal attachment and distress.

METHODS

An analytical, case-control research design was used. The study was conducted between April 2023 and March 2024. The population of the study consisted of pregnant women who presented to a training and research hospital in the north of Turkey for antenatal follow-up, and the sample consisted of 152 women from this population (case group 76 and control group 76). Data were collected using a Pregnant Descriptive Information Form, the Prenatal Attachment Inventory, and the Prenatal Distress Scale-Revised Version. The chi-square test, Mann-Whitney U test, and Spearman correlation analysis were utilized to analyze the data.

RESULTS

The prenatal attachment scores of participants who discovered their pregnancies late were significantly lower than the scores of those whose pregnancies were discovered early (p<0.05). The prenatal distress scores of participants whose pregnancies were discovered late were significantly higher than the scores of those with early discovery (p<0.05). While a statistically positive, low-level relationship was detected between the prenatal attachment and prenatal distress scores of pregnant women whose pregnancies were discovered early (p<0.05), there was no statistically significant relationship between the scores of those who discovered their pregnancies late (p>0.05).

CONCLUSION

There was a difference between the timing of pregnancy discovery and prenatal attachment and prenatal distress.

Sociodemographic and reproductive characteristics of pregnant women with unplanned pregnancy residing in the state of São Paulo, Brazil: a cross-sectional study

OBJECTIVE

The aim of our study was to assess the associated factors of planned and unplanned pregnancies (UPs) among pregnant women in São Paulo, Brazil.

METHODS

We conducted a cross-sectional study from March 2023 to June 2024 and invited pregnant women aged 18 to 49 years. We used the Brazilian-validated version of the London Measure of Unplanned Pregnancy to assess pregnancy intentions. We estimated absolute and relative frequencies of planned and UPs by sociodemographic and reproductive characteristics. Bivariate and multiple regression analysis were performed to evaluate the associated factors for UPs.

RESULTS

We included 534 participants; 65.7% reported an UP. Black or Biracial vs White women (74% vs. 57%, p < 0.001), with 0 to 9 years vs. those with >9 of schooling (77% vs. 51%, p < 0.001), and single vs married women (85% vs. 48%, p < 0.001) were associated with UPs. Parous women or those reporting a younger age at their sexual debut were more commonly reported UPs. The associated factors to UPs were being Black or Biracial (Odds ratio [OR] 1.68, 95% Confidence Interval [CI] 1.11;2.57), reporting fewer schooling years (OR 1.61, 95% CI 1.01;2.54), not being married [(OR 2.41, 95% CI 1.53;3.84) for cohabiters and OR 5.23, 95% CI 2.93;9.74) for single] and reporting additional births (OR 1.28, 95% CI 1.07;1.56).

CONCLUSION

Black or Biracial, with fewer years of schooling, not married, and parous women were at a higher risk of UPs. These women tend to face structural barriers to planning the size and timing of their families, requiring actions like increasing tertiary education access and guaranteeing universal modern contraceptive availability to leverage these disadvantages and fulfil their sexual and reproductive rights.

Pregnancy and Pregnancy Outcomes in a National Population Cohort of Patients Treated for Substance Use Disorders

OBJECTIVES

The objectives of this study were to i) provide population-level prevalence rates of pregnancy, birth, elective termination, and miscarriage among females treated for SUDs and their demographic counterparts and ii) examine associations between SUD treatment and pregnancy and elective terminations.

METHODS

Data were analyzed from a prospective registry-linkage study of all females (15-45 years) recorded as treated for SUDs in the Norwegian Patient Registry over a 2-year period (n = 6470) and a non-treated frequency-matched cohort of females from the general population (n = 6286). Pregnancy and pregnancy outcomes over a 4-year follow-up were retrieved from the Norwegian Patient Registry. Multivariable logistic regression models tested for associations of SUD treatment with pregnancy and with elective termination among pregnant females.

RESULTS

Annual pregnancy and elective termination rates per 1000 females were significantly higher for the SUD cohort than the non-treated cohort (94.2 vs 71.3 for pregnancy, P < 0.001; 54.7 vs 17.8 for elective termination, P < 0.001), the annual birth rate was lower for the SUD cohort (25.3 vs 41.8, P < 0.001), and the rate of miscarriage did not differ across cohorts. Multivariable analysis showed that SUD treatment was associated with a significant increase in the odds of pregnancy (adjusted Odds Ratio 1.34, Confidence Interval [1.18-1.54]) and the odds of an elective termination, conditional on pregnancy (aOR 2.55, Confidence Interval [1.97-3.29]).

CONCLUSIONS

Females treated for SUDs had substantially higher odds of pregnancy and elective terminations than the non-treated cohort. To improve their reproductive health, targeted interventions such as free long-acting contraception and integration of family planning guidance into substance use treatment should be considered.

From parentification to parenthood: caregiving responsibilities in childhood and childbearing desire in young adulthood

INTRODUCTION

Childbearing and childrearing challenge parents' physical, social and emotional capacities. Childbearing motivations and desires are indicators of person's psychological readiness to meet these challenges and to establish a healthy bond with the child. Yet, much uncertainty still exists on how childbearing motivations and desires develop in the life course and to what extent early experiences in the family of origin contribute to their development.

OBJECTIVE

The overall goal of the present study was to understand the relationship between early caregiving responsibilities (i.e. childhood parentification) in the family of origin and childbearing motivations and the desire to have a first child.

METHODS

In the cross-sectional design study, childless Polish adults (N = 384; 20-35 years old) completed a set of self-report measures. Different dimensions of parentification experienced in childhood were measured retrospectively using the Parentification Inventory, and childbearing-related variables were assessed using the Childbearing Questionnaire. Data were analysed using mediation analyses.

RESULTS

We found that past experiences of parent- and sibling-oriented parentification were positively associated with the desire to have a child, and these relationships were fully mediated by positive childbearing motivation. Further, our results showed that satisfaction with childhood caregiving responsibilities positively predicted childbearing desire, and this effect was partially mediated by positive and negative childbearing motivation.

CONCLUSION

Individuals' early caring activities, especially when they evoke feelings of satisfaction and appreciation in the child, may play an important role in shaping childbearing motivations and desires that underlie their future reproductive behaviours.

Iron and folic acid supplementation compliance during pregnancy and its effect on post-pregnancy anaemia among reproductive-age women in East Africa

BACKGROUND

Despite the government's effort to reduce the prevalence of anaemia among reproductive-age women globally, it continues as a significant public health issue, especially in low- and middle-income countries. Iron-folic acid (IFA) supplementation is a widely used intervention to prevent anaemia, but compliance remains a major challenge. There is a lack of literature examining IFA supplementation compliance during pregnancy and its impact on preventing and controlling anaemia during post-pregnancy in the East Africa region.

OBJECTIVE

This study aims to investigate compliance with IFA supplementation during pregnancy and its impact on post-pregnancy anaemia among reproductive-age women in East Africa.

DESIGN

This study was designed as a cross-sectional survey.

METHODS

This study used data from 43,200 reproductive-age women from 2015 to 2022 demographic and health survey datasets. We used multilevel mixed-effect logistic regression analysis to identify associated factors with IFA supplementation compliance during pregnancy. Furthermore, a propensity score matching (PSM) analysis was used to determine the effect of IFA supplementation compliance on anaemia after pregnancy among women.

RESULTS

The level of compliance with IFA supplementation during pregnancy was 31.33% (95% confidence interval (CI): 30.89, 31.77), whereas the prevalence of anaemia among reproductive-age women was 32.08% (95% CI: 31.64, 32.52). Maternal education, the timing of antenatal care (ANC) visits, wanted index pregnancy (last pregnancy), wealth status, healthcare access, mass media exposure and ANC services from skilled healthcare providers were significantly associated with compliance with IFA supplementation among pregnant women. The PSM analysis indicated a significant positive association between IFA supplementation compliance during pregnancy and prevention of post-pregnancy anaemia among reproductive-age women, with an average treatment effect on the treated (ATT) of 25.55% (ATT = -0.2555, 95% CI: -0.3440, -0.1669, p < 0.0001).

CONCLUSION

Despite universal IFA supplementation, anaemia remains prevalent in East African countries due to low level of compliance with IFA supplementation. Targeting individual and socio-economic factors during IFA supplementation promotion helps to prevent anaemia after pregnancy. Further research is recommended to gain deeper insights.

Individual- and community-level factors associated with early initiation of breastfeeding in Mozambique: evidence from the 2022-2023 Demographic and Health Survey

BACKGROUND

Early initiation of breastfeeding is defined as giving breast milk to the newborn within one hour of birth. It strengthens the link between mother and child, promotes cognitive development, and lowers the chance of obesity and non-communicable diseases during the prime years of life. Nowadays, only 50% of newborns worldwide receive breast milk within their first hour of life. This study examined the prevalence and individual- and community-level factors associated with early initiation of breastfeeding using the Demographic and Health Survey data and offers suggestions that can enhance the practice in Mozambique.

METHODS

Data from the nationally representative Mozambique Demographic and Health Survey were used in this cross-sectional analysis. The study included a weighted sample of 3,548 children born in the two years prior to the survey. Software for statistical analysis, STATA/SE version 14.0, was used to clean, recode, and analyze the data. Utilizing multilevel logistic regression, the factors associated with the outcome variable were identified. Statistical significance was attained by variables having a p-value less than 0.05.

RESULTS

The prevalence of early initiation of breastfeeding in Mozambique was 75.03% (95% CI: 73.58%, 76.43%). Factors like non-working [AOR = 0.62; 95% CI (0.50, 0.78)], wanted last pregnancy [AOR = 1.68; 95% CI (1.33, 2.12)], antenatal care attendance [AOR = 0.63; 95% CI (0.43, 0.93)], vaginal birth [AOR = 2.30; 95% CI (1.58, 3.36)], size of the child at birth [AOR = 1.77; 95% CI (1.26, 2.48)], urban residence [AOR = 2.99; 95% CI (1.90, 4.72)], community-level antenatal care utilization [AOR = 0.52; 95% CI (0.35, 0.77)], and community poverty level [AOR = 0.34; 95% CI (0.20, 0.58)] were significantly associated with early initiation of breastfeeding.

CONCLUSIONS

About three out of four newborn babies in Mozambique have an early initiation of breastfeeding. It is critical to concentrate on developing policies that support the early initiation of breastfeeding, particularly for mothers who have small children, unplanned pregnancies, non-vaginal deliveries, and reside in rural areas.

Pregnancy Intendedness Among Racial and Ethnically Minoritized Women with Disabilities

Background: A limited number of studies have examined the prevalence of unintended pregnancy among disabled women. However, no studies to date have examined the association between pregnancy intention and disability, in combination with race and ethnicity. Methods: We analyzed data from the National Survey of Family Growth from the period 2011-2019 to estimate the prevalence of pregnancy intendedness among women with disabilities 15-45 years of age. We compared pregnancy intendedness among respondents with and without disabilities. Modified Poisson regressions were conducted to estimate the unadjusted and adjusted prevalence ratios (with 95% confidence intervals) of unintended pregnancy across disability type and by race and ethnicity category. Non-Hispanic White women without disabilities served as the referent group. Results: Unadjusted results found that women with disabilities in all racial or ethnic groups were significantly more likely to report unintended pregnancies compared with non-Hispanic White women with no disabilities. Non-Hispanic Black women were more than three and a half times (PR = 3.72, 95% CI: 2.91-4.75) more likely than their non-Hispanic White counterparts to report an unintended pregnancy. After adjusting for demographic characteristics, results were slightly attenuated in all categories, with the exception of nondisabled Hispanic women, indicating high prevalence of unintended pregnancies. Conclusions: Racial and ethnic minority women with disabilities may experience heightened risk for unintended pregnancy. Targeted efforts are needed to address barriers to comprehensive sexual and reproductive health care and improve reproductive health outcomes among women who experience multiple forms of marginalization.

Pathway linking unwanted pregnancy to low birth weight in Indonesia: A conditional mediation analysis

Unwanted pregnancies resulting in detrimental consequences for both the mother and the child, including low birth weight, pose a remarkable challenge in developing countries. Although the association between low birth weight (LBW) and unwanted pregnancy is widely demonstrated, the results have been inconsistent, and the underlying mechanisms remain unclear. We examined maternal antenatal care (ANC) completeness as a potential mediating factor of the association between unwanted pregnancy and LBW among women in Indonesia, as well as the moderating effect of family support during pregnancy. We used women's records from the Indonesian Demographic and Health Survey (IDHS), a population-based survey conducted in 2017. This study involved 13,179 women aged 15-49 whose most recent child was aged 1-5 years. The multiple logistic regression results demonstrated that unwanted pregnancy was not associated with LBW. The generalized structural equation modeling (GSEM) results depicted that the effect of unwanted pregnancy on LBW was overwhelmingly explained by incomplete ANC, suggesting the mediation and suppression effect in the model (b = 0.32; 95 % Bias-corrected CI = 0.19-0.50; p = <0.001). The indirect impact of unwanted pregnancy on LBW also varied among different family support levels. This study filled the gaps in previous research on how unwanted pregnancy affects maternal and health outcomes. In conclusion, adequate ANC intervention and positive family support should be strengthened in future policy implementation to prevent the adverse effects of unwanted pregnancy.

Association between pregnancy intention and completion of newborn and infant continuum of care in Sub-Saharan Africa: systematic review and meta-analysis

BACKGROUND

The newborn and infant continuum of care such as essential newborn care, early initiation and exclusive breastfeeding, and immunisation are highly recommended for improving the quality of life and survival of infants. However, newborn and infant mortality remains high across Sub-Saharan African countries. While unintended pregnancies are associated with adverse newborn and infant health outcomes, there is inconclusive evidence on whether pregnancy intention influences newborn and infant continuum of care completion. Therefore, this review aimed to pool findings reported in the literature on the association between pregnancy intention and newborn and infant health care across the continuum of care in Sub-Saharan Africa.

METHODS

We searched MEDLINE Complete, EMBASE, CINAHL Complete, and Global Health databases for studies potentially eligible for this systematic review and meta-analysis. Two researchers independently screened the identified articles by abstract and title, and then full-text using Covidence. We used the Newcastle-Ottawa Scale to assess the quality of the included studies. The Cochran's Q test and I2 were executed to detect and quantify the presence of statistical heterogeneity in the studies. Meta-analysis was done for each outcome when more than one original study reported relevant data, using Stata statistical software version 18.

RESULTS

Eleven studies were included from a total of 235 articles identified by the search. The odds of completing essential newborn care (pooled odds ratio: 3.04, 95% CI: 1.56, 5.90), early initiation of breastfeeding (pooled odds ratio: 1.30, 95% CI: 1.13, 1.52), exclusive breastfeeding (pooled odds ratio: 2.21, 95% CI: 1.68, 2.89), and being fully immunised (pooled odds ratio: 2.73, 95% CI: 1.16, 6.40) were higher among infants born to women with intended pregnancies as compared to women with unintended pregnancies.

CONCLUSION

Intended pregnancy was positively associated with essential newborn care completion, early initiation and exclusive breastfeeding, and full immunisation of infants in SSA countries. Thus, policy-makers and stakeholders should strengthen the provision of quality family planning services to prevent unintended pregnancy. Furthermore, follow-up of women with unintended pregnancies is needed to increase women's opportunity to access essential newborn health care services that further reduce the risk of newborn and infant morbidity and mortality.

Immediate Postpartum Long-Acting Reversible Contraception for Preventing Severe Maternal Morbidity: A Cost-Effectiveness Analysis

OBJECTIVE

To estimate the cost effectiveness of Medicaid covering immediate postpartum long-acting reversible contraception (LARC) as a strategy to reduce future short interpregnancy interval (IPI), severe maternal morbidity (SMM), and preterm birth.

METHODS

We built a decision analytic model using TreeAge software to compare maternal health and cost outcomes in two settings, one in which immediate postpartum LARC is a covered option and the other where it is not, among a theoretical cohort of 100,000 people with Medicaid insurance who were immediately postpartum and did not have permanent contraception. The primary outcome was the incremental cost-effectiveness ratio (ICER), which represents the incremental cost increase per an incremental quality-adjusted life-years (QALY) gained from one health intervention compared with another. Secondary outcomes included subsequent short IPI , defined as time between last delivery and conception of less than 18 months, as well as SMM, preterm birth, overall costs, and QALYs. We performed sensitivity analyses on all costs, probabilities, and utilities.

RESULTS

Use of immediate postpartum LARC was the cost-effective strategy, with an ICER of -11,880,220,102. Use of immediate postpartum LARC resulted in 299 fewer repeat births overall, 178 fewer births with short IPI, two fewer cases of SMM, and 34 fewer preterm births. Coverage of immediate postpartum LARC resulted in 25 additional QALYs and saved $2,968,796.

CONCLUSION

Coverage of immediate postpartum LARC at the time of index delivery can improve quality of life and reduce health care costs for Medicaid programs. Expanding coverage to include immediate postpartum LARC can help to achieve optimal IPI and decrease SMM and preterm birth.

Long-term effects of unintended pregnancy on children: Findings from the Dutch prospective birth-cohort Amsterdam born children and their development study

Several studies investigated short-term risks of children born from unintended pregnancies, however evidence about long-term risks is lacking. We aimed to examine whether children born from unintended pregnancies experience psychosocial problems up into adolescence. This study is based on the longitudinal birth cohort study 'Amsterdam Born Children and their Development' (n = 7784). Unintended pregnancy was measured as a multidimensional construct, based on self-reports on the extent of pregnancy mistiming ('This pregnancy happened too soon'), unwantedness ('I did not want to be pregnant (anymore)') and unhappiness ('I am happy to be pregnant'; recoded). Further, children's psychosocial problems were measured with the Strengths and Difficulties Questionnaire, at 5-6, 11-12 and 15-16 years old. Multiple over-time associations between unintended pregnancy and children's psychosocial problems were analysed using Structural Equation Modelling, while controlling for confounders. Results showed that pregnancy mistiming was a significant predictor of internalizing (β = 0.10, p < 0.001) and externalizing problems (β = 0.07, p = 0.006) and unwanted pregnancy of internalizing problems (β = 0.13, p < 0.001) at 5-6 years. These associations were substantially mediated by maternal mental health and poorer maternal bonding. Associations were no longer present at 11-12 and 15-16 years. Thus, we conclude that children born from unintended pregnancies experience more psychosocial problems at 5-6 years, but no longer at 11-12 and 15-16 years. Unintended pregnancies often coincide with maternal mental health problems and socioeconomic factors. Most importantly, the associations between unintended pregnancy and children's psychosocial problems are influenced by maternal mental health and poorer bonding. Therefore it is important to improve maternal mental health and bonding for the benefit of both mother and child, rather than on the isolated effect of unintended pregnancy per se.

Pregnancy intendedness and happiness as predictors of maternal-foetal bonding: evidence for mediation

INTRODUCTION

Prior research has identified associations between pregnancy intendedness and maternal-foetal bonding, but no studies have examined the potential mediation of pregnancy happiness on the development of the maternal-infant relationship.

METHODS

In 2017-2018, a clinic-based pregnancy cohort of 177 low-income and racially diverse women in a South-Central U.S. state participated in a study examining their pregnancy intentions, attitudes and behaviours. Pregnancy intentions and happiness and demographic characteristics were measured during the first trimester assessment, and maternal-foetal bonding was measured with the Prenatal Attachment Inventory (PAI) during the second trimester. Structural equation modelling was used to examine the associations between intendedness, happiness and bonding.

RESULTS

Findings indicate positive associations between intended pregnancies and pregnancy happiness and pregnancy happiness to bonding. The direct effect from intended pregnancy to maternal-foetal bonding was not significant, providing evidence for full mediation. We did not find any associations between pregnancies that were unintended or ambivalent with pregnancy happiness or maternal-foetal bonding.

CONCLUSIONS

Pregnancy happiness provides one potential explanation for the association between intended pregnancies and maternal-foetal bonding. These findings have implications for research and practice, as inquiring about mothers' pregnancy attitudes (e.g. how happy they are about their pregnancy) may be more important for maternal psychological health outcomes, such as the maternal-child relationship, than whether or not their pregnancies were intended.

Racial/Ethnic Differences in Relationships Between Pregnancy Intentions and Maternal Outcomes

Unplanned or unwanted pregnancies and births are linked to adverse maternal outcomes, but the extent to which such relationships hold for all racial/ethnic groups remains unknown. In this paper, I use large-scale data to estimate unadjusted and inverse propensity weighted associations between a five-level measure of pregnancy intention and six indicators of maternal well-being among separate samples of white, Black, and Hispanic mothers. I find substantial racial/ethnic variation. White and Hispanic mothers who reported that their pregnancies were mistimed, unwanted, or that they were unsure how they felt were significantly more likely to experience adverse outcomes than same-race/ethnicity mothers who reported that their pregnancy was intended, but the pattern was much more tenuous for Black mothers. After adjusting for potential confounding variables, relationships between pregnancy intentions and adverse outcomes remain substantial only for white and Hispanic mothers.

Do black women's lives matter? A study of the hidden impact of the barriers to access maternal healthcare for migrant women in South Africa

Background

Studies on the barriers migrant women face when trying to access healthcare services in South Africa have emphasized economic factors, fear of deportation, lack of documentation, language barriers, xenophobia, and discrimination in society and in healthcare institutions as factors explaining migrants' reluctance to seek healthcare. Our study aims to visualize some of the outcome effects of these barriers by analyzing data on maternal death and comparing the local population and black African migrant women from the South African Development Countries (SADC) living in South Africa. The heightened maternal mortality of black migrant women in South Africa can be associated with the hidden costs of barriers migrants face, including xenophobic attitudes experienced at public healthcare institutions.

Methods

Our analysis is based on data on reported causes of death (COD) from the South African Department of Home Affairs (DHA). Statistics South Africa (Stats SA) processed the data further and coded the cause of death (COD) according to the WHO classification of disease, ICD10. The dataset is available on the StatsSA website (http://nesstar.statssa.gov.za:8282/webview/) for research and statistical purposes. The entire dataset consists of over 10 million records and about 50 variables of registered deaths that occurred in the country between 1997 and 2018. For our analysis, we have used data from 2002 to 2015, the years for which information on citizenship is reliably included on the death certificate. Corresponding benchmark data, in which nationality is recorded, exists only for a 10% sample from the population and housing census of 2011. Mid-year population estimates (MYPE) also exist but are not disaggregated by nationality. For this reason, certain estimates of death proportions by nationality will be relative and will not correspond to crude death rates.

Results

The total number of female deaths recorded from the years 2002 to 2015 in the country was 3740.761. Of these, 99.09% (n = 3,707,003) were deaths of South Africans and 0.91% (n = 33,758) were deaths of SADC women citizens. For maternal mortality, we considered the total number of deaths recorded for women between the ages of 15 and 49 years of age and were 1,530,495 deaths. Of these, deaths due to pregnancy-related causes contributed to approximately 1% of deaths. South African women contributed to 17,228 maternal deaths and SADC women to 467 maternal deaths during the period under study. The odds ratio for this comparison was 2.02. In other words, our findings show the odds of a black migrant woman from a SADC country dying of a maternal death were more than twice that of a South African woman. This result is statistically significant as this odds ratio, 2.02, falls within the 95% confidence interval (1.82-2.22).

Conclusion

The study is the first to examine and compare maternal death among two groups of women, women from SADC countries and South Africa, based on Stats SA data available for the years 2002-2015. This analysis allows for a better understanding of the differential impact that social determinants of health have on mortality among black migrant women in South Africa and considers access to healthcare as a determinant of health. As we examined maternal death, we inferred that the heightened mortality among black migrant women in South Africa was associated with various determinants of health, such as xenophobic attitudes of healthcare workers toward foreigners during the study period. The negative attitudes of healthcare workers toward migrants have been reported in the literature and the media. Yet, until now, its long-term impact on the health of the foreign population has not been gaged. While a direct association between the heightened death of migrant populations and xenophobia cannot be established in this study, we hope to offer evidence that supports the need to focus on the heightened vulnerability of black migrant women in South Africa. As we argued here, the heightened maternal mortality among migrant women can be considered hidden barriers in which health inequality and the pervasive effects of xenophobia perpetuate the health disparity of SADC migrants in South Africa.

Catholic Hospital Affiliation and Postpartum Contraceptive Care and Subsequent Deliveries

Importance

In recent years, the number of Catholic hospitals has grown, raising concerns about access to contraception. The association between living in an area in which the closest hospital is Catholic and the probability of postpartum contraception and subsequent deliveries is unknown.

Objective

To assess whether living in an area in which the closest hospital was Catholic was associated with the probability of postpartum contraception and subsequent deliveries.

Design, Setting, and Participants

This cohort study used data from the Healthcare Cost and Utilization Project's State Inpatient Databases, State Emergency Department Databases, and State Ambulatory Surgery and Services Databases for 11 states (California, Florida, Georgia, Missouri, Nebraska, Nevada, New York, South Carolina, Tennessee, Vermont, and Wisconsin). Female patients with a delivery from 2016 to 2019 who lived within 20 miles of a nonfederal acute care hospital were included, with patients followed up for 1 to 3 years. Coarsened exact matching was used to match patients based on the county-level percentage of the population affiliated with Catholic churches and urbanicity, and the zip code-level number of hospitals within 5 and 20 miles, median household income, and percentage of the population by race and ethnicity. Data were analyzed from April 2022 to November 2023.

Exposures

Residence in a zip code in which the closest hospital was Catholic.

Main Outcomes and Measures

Probabilities of delivery at a Catholic hospital, surgical sterilization within 1 year of delivery, receipt of long-acting reversible contraception at delivery, and subsequent delivery within 3 years.

Results

The sample consisted of 4 101 443 deliveries (1 301 792 after matching), with 14.5% of patients living in exposed zip codes (ie, where the closest hospital was Catholic). Living in exposed zip codes was associated with a 21.26-percentage point (pp) increase in the probability of delivery at a Catholic hospital (95% CI, 19.50 to 23.02 pp; 237.3% relative to the mean in unexposed zip codes; P < .001). Additionally, comparing exposed vs unexposed zip codes, the probability of surgical sterilization at delivery decreased by 0.95 pp (95% CI, -1.14 to -0.76 pp; P < .001) and the probability of sterilization in the year after discharge further decreased by 0.21 pp (95% CI, -0.29 to -0.13; P < .001). Subsequent deliveries within 3 years increased 0.47 pp (95% CI, -0.03 to 0.97 pp; 2.3% relative to the mean in unexposed zip codes; P = .07).

Conclusions and Relevance

This cohort study finds that living in a zip code in which the closest hospital was Catholic was associated with a modest decrease in the probability of postpartum surgical sterilizations and a modest increase in the probability of subsequent deliveries.

An exploration of the contraceptive counselling practices of midwives who provide postpartum care in Australia

OBJECTIVE

We sought to explore and describe midwives' attitudes and practices relating to their provision of postpartum contraception counselling.

DESIGN

We used an exploratory cross-sectional design. Recruitment used an anonymous online survey using electronic communication platforms of professional, and special-interest organisations, over six months . Descriptive and quantitative analysis was used.

SETTING AND PARTICIPANTS

Australian Midwives who provide postpartum care.

MEANING AND FINDINGS

A total of 289 complete responses were included. Findings from this national survey of midwives showed that almost 75% of Australian midwives reported providing some contraceptive advice to women. Those working in continuity of care models were significantly more likely to fulfil this responsibility. More than half (67%) indicated they had not received any formal contraception education or training. Those working in private obstetric-led settings were significantly less likely to have received education compared to midwives in community settings. Systems barriers preventing the provision of contraceptive counselling included: clinical workload; lack of management support; lack of education; and models of care.

KEY CONCLUSIONS

Most midwives (82%) wanted to provide postpartum contraception counselling as part of their role. They cited barriers from within the health system, ambiguity about roles and responsibilities and offered solutions to improve the provision of postnatal contraception counselling.

IMPLICATIONS FOR PRACTICE

Recommendations include the development of education programs for midwives. Continuity of care models provided the time, autonomy and opportunity for midwives to undertake contraceptive counselling and fulfil this part of their professional scope. Consideration should be given to expanding access and provision of continuity of midwifery care. An urgent investment in the education and skills of midwives is recommended to ensure all women across acute and community services benefit from improved outcomes associated with pregnancy spacing.

Pregnancy planning and neonatal outcome - a retrospective cohort study

BACKGROUND

Unplanned pregnancy is common, and although some research indicates adverse outcomes for the neonate, such as death, low birth weight, and preterm birth, results are inconsistent. The purpose of the present study was to investigate associated neonatal outcomes of an unplanned pregnancy in a Swedish setting.

METHODS

We conducted a retrospective cohort study in which data from 2953 women were retrieved from the Swedish Pregnancy Planning Study, covering ten Swedish counties from September 2012 through July 2013. Pregnancy intention was measured using the London Measurement of Unplanned Pregnancy. Women with unplanned pregnancies and pregnancies of ambivalent intention were combined and referred to as unplanned. Data on neonatal outcomes: small for gestational age, low birth weight, preterm birth, Apgar score < 7 at 5 min, and severe adverse neonatal outcome defined as death or need for resuscitation at birth, were retrieved from the Swedish Medical Birth Register.

RESULTS

The prevalence of unplanned pregnancies was 30.4%. Compared with women who had planned pregnancies, those with unplanned pregnancies were more likely to give birth to neonates small for gestational age: 3.6% vs. 1.7% (aOR 2.1, 95% CI 1.2-3.7). There were no significant differences in preterm birth, Apgar score < 7 at 5 min, or severe adverse neonatal outcome.

CONCLUSIONS

In a Swedish setting, an unplanned pregnancy might increase the risk for birth of an infant small for gestational age.

A Multidimensional and Longitudinal Exploratory Study of the Stability of Pregnancy Contexts in the United States

Objective

Evaluate the longitudinal stability of six pregnancy contexts, including intention, in a diverse cohort of individuals experiencing delivery, abortion, or miscarriage.

Methods

We enrolled individuals 16-44 years of age with pregnancies <24 weeks gestation in this longitudinal study between June 2014 and June 2015 in four US urban clinics. We assessed six pregnancy contexts (intention, wantedness, planning, timing, desirability, and happiness) at enrollment and 3-month follow-up. We constructed three-level categorical measures for each context defined as favorable, ambivalent, or unfavorable. We used Wilcoxon sign tests to evaluate changes in paired observations between pregnancy context measures over time and by pregnancy outcome.

Results

Among 121 participants at median gestational age of 7 weeks and 3 days, we found intention, wantedness, planning, timing, and happiness remained unchanged from enrollment in early pregnancy to 3-month follow-up. Individuals demonstrated changes in desirability; pregnancy assessments shifted toward less desirable from enrollment to follow-up (p = 0.01) (i.e., desired to ambivalent, or ambivalent to undesired). Among participants choosing delivery (57%), assessments shifted toward more favorable planning (i.e., unplanned to ambivalent, or ambivalent to planned) (p < 0.01), and less favorable desirability (i.e., desired to ambivalent or ambivalent to undesired) (p < 0.01) at follow-up. Among participants choosing abortion (28%), assessments shifted toward more unfavorable planning (i.e., planned to ambivalent, or ambivalent to unplanned) at follow-up (p < 0.01).

Conclusion

In multidimensional, longitudinal assessment, pregnant participants' perspectives on five of six pregnancy contexts remained unchanged between enrollment and 3-month follow-up; only desirability shifted. Pregnancy planning perspectives differed by pregnancy outcome.Human Research Subjects Protection Program: 1310012926.

Maternal childhood adversity and pregnancy intentions as predictors of pregnancy happiness

OBJECTIVES

Nearly half of all pregnancies in the U.S. are classified as unintended (e.g. unplanned, mistimed, or unwanted), which have been linked to numerous adverse consequences for maternal and child outcomes. Recent evidence suggests that happiness about a pregnancy is often a better predictor of maternal and infant health outcomes than pregnancy intentions, but few studies have examined maternal predictors of pregnancy happiness.

METHODS

Using a clinic-based sample of pregnant women (n = 177), we apply multiple regression analysis to examine the association between maternal adverse childhood experiences and pregnancy happiness, as well as the moderating role of pregnancy intentions.

RESULTS

Women with more childhood adversity and pregnancies that were unplanned and mistimed or unwanted reported lower levels of pregnancy happiness, compared with women with less childhood adversity and intended pregnancies. However, pregnancy intentions did not moderate the relationship between maternal adverse childhood experiences and pregnancy happiness.

CONCLUSION

Our results suggest that pregnancy happiness is lower among mothers with a history of childhood adversity and pregnancies classified as unplanned and mistimed or unwanted. Understanding the factors that impact pregnancy happiness is critical to inform prenatal clinical practice and health policy, particularly when caring for those with a history of adversity.

Correlates of Unmet Need for Modern Contraception Among Reproductive-Aged Women Involved in New York City Criminal Legal Systems

Introduction

The population of women involved in criminal legal systems (WICL), a majority of whom are reproductive-aged, has risen steadily in the United States. They contend with numerous barriers to sexual and reproductive health services resulting in high rates of unmet need for contraception and unintended pregnancy.

Materials and Methods

This study included 132 non-pregnancy seeking reproductive-aged WICL enrolled in the baseline assessment of the HIV prevention intervention, "Women on the Road to Health" (WORTH). A multivariate generalized linear logistic regression model with robust estimation examined effects of past 6-month intimate partner violence (IPV; sexual and physical/injurious), past 3-month substance use (binge drinking, cannabis, other illegal drug use), and lifetime mental health diagnoses (anxiety, depression, bipolar disorder) on women's unmet need for modern contraception, adjusting for significant demographic and socioeconomic factors.

Results

Women who were younger in age (odds ratio [OR]: 0.74; 95% confidence interval [CI]: 0.63-0.88) and reporting lifetime diagnoses of anxiety disorders (OR: 13.64; 95% CI: 2.71-68.34) were significantly more likely to meet the criteria for unmet need for modern contraception. Women with a regular gynecologist (OR: 0.11; 95% CI: 0.01-0.86) reporting lifetime diagnoses of bipolar disorder and past 6-month sexual IPV histories (OR: 0.04; 95% CI: 0.002-0.86) were significantly less likely to meet the criteria for unmet need for modern contraception.

Conclusions

Distinct mental health diagnoses and experiences of IPV may uniquely impact unmet need for modern contraception among WICL. These findings emphasize the need for a more nuanced comprehension of these relationships to deliver comprehensive and holistic health services that address the intersecting needs of this population.

Reproductive autonomy and the experience of later-than-desired pregnancy: results from a cross-sectional survey of reproductive-aged women in Uganda

BACKGROUND

The focus of reproductive autonomy research has historically been on the experience of unintended pregnancy and use of contraceptive methods. However, this has led to the neglect of a different group of women who suffer from constraints on their reproductive autonomy-women who experience pregnancies later than they desire or who are unable to become pregnant. This study examines the extent of later-than-desired pregnancy among women and evaluates the sociodemographic and reproductive factors associated with this experience in Uganda.

METHODS

We use data from the Performance Monitoring for Action Uganda 2022 female survey. We restricted the nationally representative sample of reproductive-aged women to those who were currently pregnant or who had ever given birth (n = 3311). We compared the characteristics of women across fertility intention categories (wanted pregnancy earlier, then, later, or not at all) of their current or most recent birth and used multivariable logistic regression to examine factors independently associated with having a pregnancy later than desired compared to at a desired time.

RESULTS

Overall, 28.3% of women had a later-than-desired pregnancy. Nearly all sociodemographic and reproductive characteristics were associated with the desired pregnancy timing of women's current or most recent pregnancy. Having higher education [adjusted odds ratio (aOR) 2.41, 95% confidence interval (CI) 1.13-5.13], having sought care for difficulties getting pregnant (aOR 2.12, 95% CI 1.30-3.46), and having less than very good self-rated health (good health aOR 1.74, 95% CI 1.12-2.71; moderate health aOR 1.77, 95% CI 1.09-2.86; very bad health aOR 4.32, 95% CI 1.15-16.26) were all independently significantly associated with increased odds of having a later-than-desired pregnancy. Being nulliparous (aOR 1.98, 95% CI 0.99-3.95) was also borderline significantly associated with having a later-than-desired pregnancy.

CONCLUSIONS

Identifying those who have later-than-desired pregnancies is essential if we seek to make progress towards supporting women and couples in achieving their reproductive goals, not just preventing pregnancies. Research on desired pregnancy timing in sub-Saharan Africa should be expanded to capture later-than-desired pregnancies, a population which is invisible in existing data. This work has public health implications due to commonalities in the factors associated with mistimed and unintended pregnancies and their link to poorer health and potentially poorer pregnancy outcomes.

Patterns in the provision of government-subsidised hormonal postpartum contraception in Queensland, Australia between 2012 and 2018: a population-based cohort study

BACKGROUND

Short birth intervals and unintended pregnancy are associated with poorer maternal and infant outcomes. There is a risk of pregnancy during the immediate postpartum period unless contraception is initiated. This retrospective cohort study aimed to capture the current patterns of hormonal contraceptive provision within 12 months postpartum in a high-income country.

METHODS

We used a linked administrative dataset comprising all women who gave birth in Queensland, Australia between 1 July 2012 and 30 June 2018 (n=339 265 pregnancies). We described our cohort by whether they were provided with government-subsidised hormonal contraception within 12 months postpartum. The associations between hormonal postpartum contraceptive provision and demographic and clinical characteristics were examined using univariate and multivariate logistic regression and presented in terms of crude and adjusted odds ratios with 95% confidence intervals.

RESULTS

A majority of women (60.2%) were not provided with government-subsidised hormonal postpartum contraception within 12 months postpartum. Women who were younger (<25 years), were overweight or obese, smoked, were born in Australia, were non-Indigenous, gave birth in a public hospital, or were in the lowest socioeconomic status group were more likely to be provided with postpartum contraception after adjusting for other covariates, compared with their counterparts.

CONCLUSIONS

Strategies to increase the provision and uptake of contraception in the immediate postpartum period are needed to prevent short birth intervals and unintended pregnancy and ensure women's fertility intentions are enacted. Ongoing research is needed to examine the factors influencing women's access to contraceptive services and, further, the types of contraception provided.

Impact of unplanned pregnancy on neonatal outcomes: findings of new high-risk newborns in Peru

BACKGROUND

Unplanned pregnancy is a significant public health problem, especially in low- to middle-income countries. The objective of this study was to determine the neonatal outcomes associated with unplanned pregnancy in a public hospital in southern Peru.

METHODS

A cross-sectional analytical study was conducted from June to August 2021 among 306 mothers and their newborns selected by convenience sampling. After obtaining informed consent, mothers were surveyed during their postpartum hospitalization about their pregnancy intentions. Unintended pregnancy was considered when it was mistimed or unwanted. Neonatal outcomes were assessed by reviewing medical records prior to discharge, evaluating the presence of low birth weight, insufficient birth weight, prematurity, respiratory distress syndrome, sepsis and neonatal mortality. Association was measured in terms of prevalence ratio (PR) and beta coefficient and respective 95% CIs, crude and adjusted for variables that obtained a value of p<0.20 in the crude model (maternal age, education and parity).

RESULTS

The overall unplanned pregnancies rate was 65%, of which 40.5% were mistimed pregnancies and 24.5% unwanted pregnancies. Unplanned and mistimed pregnancies were significantly associated with insufficient birth weight [adjusted prevalence ratio (aPR)=2.14; 95% CI 1.01 to 4.56 and aPR=2.43; 95% CI 1.09 to 5.39, respectively] and unwanted pregnancies were significantly associated with preterm birth (aPR=3.49; 95% CI 1.01 to 12.11). Furthermore, adjusted analysis showed that birth weight and gestational age were lower in unplanned, mistimed and unwanted pregnancies.

CONCLUSIONS

Unplanned pregnancy was associated with lower birth weight and shorter gestational age of newborns. These data collected in a public hospital in a developing country may have significant implications today. If pregnancy intention is not included as a neonatal risk factor, insufficient birth weight and preterm birth could increase because a higher proportion of births will be unplanned.

Breastfeeding and Hormonal Contraception: A Scoping Review of Clinical Guidelines, Professional Association Recommendations, and the Literature

Background: Postpartum contraceptive use can help prevent short-interval pregnancies, which have been associated with adverse neonatal and maternal health outcomes. Many contraceptive methods are safe for postpartum use, but patients and providers may be confused as to what impact hormonal contraception has on lactation. We performed a scoping review of the most recent U.S.-based guidelines regarding hormonal contraception on lactation to provide synthesis and recommendations to aid providers in counseling their patients. Methods: We conducted a scoping review by identifying the most recent clinical recommendations and guidelines from the Centers for Disease Control and Prevention (CDC) and three maternal and child health professional associations (American College of Obstetricians and Gynecologists [ACOG], Society for Maternal-Fetal Medicine [SMFM], and Academy of Breastfeeding Medicine [ABM]). We also reviewed the citations in these guidelines used in their development. We then conducted an updated literature review to capture studies published since the most recent systematic reviews were conducted. Results: We reviewed 1 clinical guideline from the CDC and 2 systematic reviews cited in its references, 6 professional association recommendations, and 28 publications identified through the updated literature review. Progestin-only contraceptive methods continue to demonstrate safety in breastfeeding patients, while low-quality evidence supports concerns of decreased milk supply with combined hormonal contraception. Discussion: Organizations should consider updating counseling recommendations regarding progestin-only contraceptives and lactation. Further research is needed to examine new contraceptive methods as well as the effect of hormonal contraception on lactation in the setting of preterm birth.

A partner-specific critique of mistimed and unwanted fertility: Results from an analysis of the 2017-2019 United States National Survey of Family Growth

CONTEXT

Despite substantial critiques of retrospective measures of fertility intentions, researchers widely use the metrics of unwanted and mistimed pregnancies as tools for monitoring patterns and trends in reproductive health. However, in focusing exclusively on the timing and numeric elements of fertility these constructs ignore partner-specific desires, which may lead to considerable measurement error and threaten their validity.

METHODOLOGY

We use data on births in the last 5 years from the 2017-2019 United States National Survey of Family Growth to compare responses to the standard retrospective measure of fertility intentions with responses to a partner-specific question that asks respondents about whether they had ever desired a child with that partner.

RESULTS

We find that women's responses to questions on retrospective fertility desires with and without reference to a particular partner vary in ways that suggest that women and researchers interpret these questions differently.

DISCUSSION

Despite a long history in fertility research, the standard approach to measuring mistimed and unwanted fertility is both conceptually and operationally flawed. In the context of complicated sexual and reproductive lives that do not start and end with a single partner, researchers should reevaluate the usefulness of the constructs of mistimed and unwanted fertility. We conclude by offering recommendations for analysts and survey designers as well as by calling for a move away from the terms entirely to focus instead on the pregnancies that women themselves view as most problematic.

Contraceptive Behavior Dynamics and Unintended Pregnancy: A Latent Transition Analysis

The average U.S. woman wants to have two children; to do so, she will spend about three years pregnant, postpartum, or trying to become pregnant, and three decades trying to avoid pregnancy. However, few studies have examined individual patterns of contraceptive use over time. These trajectories are important to understand given the high rate of unintended pregnancy and how little we know about the complex relationship between contraceptive use, pregnancy intention, and patterns of reproductive behavior. We use data from the 2015-2017 National Survey of Family Growth to examine reproductive behavior and pregnancies across three years of calendar data. We identify seven behavior typologies, their prevalence, how women transition between them, and how pregnancies affect transitions. At any given time, half of women are reliably using contraception. A small proportion belong to a high pregnancy risk profile of transient contraceptive users, but some transition to using condoms or other methods consistently. An unintended pregnancy may initiate a transition into stable contraceptive use for some women, although that is primarily condom use. These findings have important implications for the ways contraception fits into women's lives and how that behavior interacts with relationships, sex, and life stage trajectories.

Women with substance use disorders are highly impacted by the overturning of Roe v. Wade: Advocacy steps are urgently needed

The Supreme Court's ruling to overturn the 1973 Roe v. Wade verdict represents a major setback for women's reproductive freedoms in the United States. This ruling revokes constitutional protection for abortion rights and returns the decision to the states. Since this ruling in June 2022, numerous states have adopted total or near total abortion bans, with many of these bans offering no exception for rape, incest, or nonfatal maternal health risks. Legal experts also warn that this ruling can open the door to restrict contraceptive rights previously protected under the same implied constitutional right to privacy as abortion. Already, this decision has increased momentum for states to place restrictions on specific forms of contraception. Certain groups of women will be disproportionately harmed by these bans, such as women with substance use disorders (SUDs). Women with SUDs face unique barriers to sexual and reproductive health services that exist at the structural level (e.g., criminalization; costs and accessibility), interpersonal level (e.g., higher rates of intimate partner violence) and individual level (e.g., reduced reproductive autonomy). These synergistic barriers interact to produce lower contraceptive use, increased unintended pregnancy rates, and subsequently a greater need for abortion services among this population. This ruling will exacerbate the effects of these barriers on women with SUDs, resulting in even greater difficulties accessing contraceptive and abortion services, and ultimately increasing rates of criminalization among pregnant and parenting women with SUDs. This commentary describes these barriers and highlights potential advocacy steps that are urgently needed to assist reproductive-aged women with SUDs during these challenging times when essential health services are increasingly inaccessible.

Pregnancy intentions and its associated factors among married women in resunga, Gulmi, Nepal

Pregnancy intention refers to a women's thinking at the time she became aware that she was pregnant. It can be categorized as intended and unintended. Identifying pregnancy intentions during prenatal periods help to employ careful monitoring of pregnancy that is at high risk for mother and children's health outcomes. Unintended pregnancy is a contributing factor for maternal and infant mortality, which is still high in Nepal. Reproductive and family planning program should incorporate pregnancy intention domains in health education and counseling with priority to design program to address and reduce unintended pregnancy. This brief research examines the pregnancy intentions and its associated factors among married women so that it could identify the intentions of pregnancy and factors influencing unintended pregnancy and could be useful to improve and maintain the health and well-being of women, family, community, and nation.

Postpartum Contraceptive Use, Pregnancy Intentions in Women With and Without a Delivery of a NAS-Affected Infant in Delaware, 2012-2018

Objective

Assess differences in postpartum contraceptive use and pregnancy intentions in women with a recent live birth who delivered a neonatal abstinence syndrome (NAS) affected infant.

Study Design

Using linked Delaware Birth Certificate Data, Hospital Discharge Data and PRAMS data for 2012-2018 (n = 6,358 singleton births), we assessed differences among women with and without a delivery of an NAS-affected infant by effective postpartum contraceptive use and pregnancy intentions. We calculated prevalence estimates, crude (cPOR), and prevalence odds ratios adjusted (aPOR) for NAS by maternal characteristics. We used alpha ≤ 0.05 to determine statistical significance.

Results

Prevalence of NAS was 2.2% (95% CI: 1.8 - 2.6). Effective postpartum contraceptive use was 60.4% (95% CI: 51.9-69.0) among women with delivery of an NAS-affected infant compared with a non-NAS delivery 56.4% (95% CI: 55.1-57.8%) and cPOR was 1.2 (95% CI: 0.8-1.7). Prevalence of intended pregnancy was 26.5% (95% CI: 18.9-34.0) among women with delivery of an NAS-affected infant compared with a non-NAS delivery 53.0% (95% CI: 51.7-54.4) and cPOR was 0.3 (95% CI: 0.2-0.5). After adjustment, women who delivered an NAS-affected infant had lower odds (aPOR = 0.5; 95% CI: 0.3-0.8) of indicating that their pregnancy was intended as compared to those who did not deliver an NAS-affected infant.

Conclusions

Our study found no association between delivery of an NAS-affected infant and use of an effective postpartum contraceptive method. However, we found that pregnancy intendedness was lower among women delivering an NAS-affected infant compared with women without an NAS delivery even after accounting for maternal characteristics.

Pregnancy Intention, Changes in Pregnancy Intention, and Pregnancy Incidence Among Female Nurses in North America

Importance

Pregnancy intention assessment is a key element of preconception and contraceptive care. The association between a single screening question and the incidence of pregnancy is unknown.

Objective

To prospectively evaluate the dynamics of pregnancy intention and pregnancy incidence.

Design, Setting, and Participants

This prospective cohort study (the Nurses' Health Study 3) was conducted from June 1, 2010, to April 1, 2022, in 18 376 premenopausal, nonpregnant female nurses aged 19 to 44 years.

Main Outcomes and Measures

Pregnancy intention and pregnancy status were assessed at baseline and approximately every 3 to 6 months thereafter. Cox proportional hazards regression models were used to estimate the association between pregnancy intention and pregnancy incidence.

Results

A total of 18 376 premenopausal, nonpregnant women (mean [SD] age, 32.4 [6.5] years) participated in the study. At baseline, 1008 women (5.5%) were trying to conceive, 2452 (13.3%) were contemplating pregnancy within 1 year, and the remaining 14 916 (81.2%) were neither trying to conceive nor thought they would be pregnant within 1 year. A total of 1314 pregnancies were documented within 12 months of pregnancy intention assessment. The cumulative incidence of pregnancy was 38.8% in women actively trying to conceive (median [IQR] time to pregnancy, 3.3 [1.5-6.7] months), 27.6% in women contemplating pregnancy (median [IQR] time to pregnancy, 6.7 [4.2-9.3] months), and 1.7% in women neither trying to conceive nor contemplating pregnancy (median [IQR] time to pregnancy, 7.8 [5.2-10.5] months) among those who became pregnant. Women who were actively trying to conceive were 23.1 times (95% CI, 19.5-27.4 times) and women who were contemplating pregnancy were 13.0 times (95% CI, 11.1-15.2 times) more likely to conceive within 12 months than women who were neither attempting nor contemplating pregnancy. Among women contemplating pregnancy at baseline who did not get pregnant during follow up, 18.8% were actively trying and 27.6% were not trying by 12 months. Conversely, only 4.9% of women neither trying to conceive nor contemplating pregnancy within 1 year at baseline changed pregnancy intention during follow up.

Conclusions and Relevance

In this cohort study of reproductive-aged nurses in North America, pregnancy intention was highly fluid among women who were contemplating pregnancy but relatively stable among women trying to conceive and women who were neither trying to conceive nor contemplating pregnancy. Pregnancy intention was strongly associated with pregnancy incidence, but the median time to pregnancy points to a relatively short time window to initiate preconception care.

The prevalence and variations in unintended pregnancy by socio-demographic and health-related factors in a population-based cohort of young Australian women

OBJECTIVE

The aim of this study is toestimate the prevalence of unintended pregnancy and associated socio-demographic and health-related factors among a national cohort of young Australian women.

METHODS

Secondary analysis of three waves (2013-2015) of the Australian Longitudinal Study on Women's Health new young cohort. Women born between 1989 and 1995 were recruited through internet and traditional media, and peer referral. Respondents completed a baseline web-based survey in 2013 (n=17,010) on their health and healthcare use and were followed up annually. This analysis uses data from women reporting ever having vaginal sex in waves 2 (n=9,726/11,344) and 3 (n=6,848/8,961). We assessed correlates of lifetime and recent unintended pregnancy using multivariable regression models.

RESULTS

At wave 2, among women aged 19-24, lifetime prevalence of unintended pregnancy was 12.6%, rising to 81.0% among ever pregnant women. Pregnancy outcomes among women with a history of unintended pregnancy differed by geographical residence. Disparities in odds of unintended pregnancy were seen by relationship and educational status, contraceptive use, sexual coercion and risky alcohol use.

CONCLUSIONS

Unintended pregnancy among young Australians is disproportionally experienced by women with structural disadvantages and exposure to sexual coercion.

PUBLIC HEALTH IMPLICATIONS

Service improvements to achieve equitable distribution of contraception and abortion services must be integrated with initiatives responding to sexual coercion.

Factors associated with long-acting reversible contraception usage: Results from the National Survey of Family Growth

OBJECTIVE

The authors aimed to identify factors associated with long-acting reversible contraception (LARC) usage.

METHODS

The current cross-sectional study used data from the National Survey of Family Growth from 2011 to 2019. Respondents aged 15 to 44 years were included. Those with previous sterilization, infertility, or pregnant were excluded. The outcome evaluated was use of a LARC.

RESULTS

Of 61 543 814 women, 44 287 911 (72.0%) met inclusion criteria. The rate of LARC use was 13.4%. Factors associated with an increased likelihood of LARC usage were married/living with a partner (adjusted relative risk [aRR], 1.18 [95% CI, 1.02-1.37]), perceived good health (aRR, 1.44 [95% CI, 1.13-1.84]), year of survey 2017 to 2019 (aRR, 1.53, [95% CI, 1.28-1.83]), one or two past pregnancies (aRR, 1.62 [95% CI, 1.24-2.12]) or three or more past pregnancies (aRR, 1.67 [95% CI, 1.22-2.28]), age at first live birth <20 years (aRR, 1.58 [95% CI, 1.20-2.08]) or 20 to 24 years (aRR, 1.45 [95% CI, 1.13-1.87]), age at onset of sexual activity 13-19 years (aRR, 1.50 [95% CI, 1.26-1.78]), and a 0- to 5-month period of nonintercourse in the past year (aRR, 1.63 [95% CI, 1.40-1.90]). Factors associated with decreased LARC usage were age ≥ 35 years (aRR, 0.74 [95% CI, 0.65-0.85]), being non-Hispanic Black (aRR, 0.75 [95% CI, 0.62-0.89]) or non-Hispanic other (aRR, 0.72 [95% CI, 0.59-0.88]), intending to have children (aRR, 0.65 [95% CI, 0.57-0.74]), and never being sexually active (aRR, 0.10 [95% CI, 0.06-0.16]).

CONCLUSIONS

Using a nationally representative sample of women in the United States, the authors identified modifiable factors associated with LARC use. Results may be used to plan interventional trials to increase LARC usage.

"ContraceptED": A Multidisciplinary Framework for Emergency Department-Initiated Contraception

Emergency departments (EDs) are common access points for patients who are at high risk for unintended pregnancy. Low-barrier access to effective contraception represents a crucial and low-cost intervention to address this public health need. Same-day initiation of contraception during an ED visit is a unique opportunity to provide reproductive health care for high-risk patients with otherwise limited health care access. We collaborated with our obstetrics and gynecology (OB/GYN) department, pharmacists, and a team of community health advocates to support emergency clinicians (namely, emergency physicians and advanced practice providers) in assessing pregnancy and contraceptive readiness, increasing proficiency in contraception counseling, prescribing hormonal contraception, counseling on barrier and emergency contraception, and inserting (and removing) the Nexplanon implant, a form of long-acting reversible contraception. With this novel approach, we found that emergency clinicians voluntarily participated in trainings on contraception, including low-threshold long-acting reversible contraception initiation; and, after completing these trainings, clinicians integrated these skills into their workflow in the ED. We report our results after screening 38 patients during our current Pilot Phase of implementing this program.

Measures of Pregnancy Intention: Why Use Them and What Do They Tell Us?

Understanding pregnancy intention is an important public health measure that captures the ability of individuals to access information, resources, and services needed to plan the timing and spacing of pregnancies. Pregnancy intention is a complex construct impacted by social, emotional, financial, cultural, and contextual factors. In this review, we will examine the range of available tools for individuals and populations to evaluate pregnancy intention, the timing of the tools in relation to pregnancy, their interpretation, and use for policy and practice. Traditionally, pregnancy intention was only assessed in population health surveys; however, more sophisticated tools and measures have been developed. These tools can be used at several time points: before pregnancy, during pregnancy, or after the pregnancy has ended. It is important to appreciate the varied contexts globally for women and their partners when assessing pregnancy intention, and the ability of a given tool to capture this when used retrospectively or prospectively. These tools can inform targeted delivery of services for a person or couple before, during, and after pregnancy. This knowledge can inform strategies at an individual, community, and population level as an indicator of access to sexual and reproductive health information and knowledge and uptake of preconception health.

Clustering of characteristics associated with unplanned pregnancies: the generation R study

Background

Unplanned or unintended pregnancies form a major public health concern because they are associated with unfavorable birth outcomes as well as social adversity, stress and depression among parents-to-be. Several risk factors for unplanned pregnancies in women have previously been identified, but studies usually take a unidimensional approach by focusing on only one or few factors, disregarding the possibility that predictors might cluster. Furthermore, data on predictors in men are largely overlooked. The purpose of this study is to determine predictors of unplanned versus planned pregnancy, to determine predictors of ambivalent feelings regarding pregnancy, and to investigate how characteristics of men and women with an unplanned pregnancy cluster together.

Methods

This study was embedded in Generation R, a multiethnic population-based prospective cohort from fetal life onwards. Pregnancy intention was reported by 7702 women and 5367 partners. Information on demographic, mental, physical, social, and sexual characteristics was obtained. Logistic regression, multinomial regression and cluster analyses were performed to determine characteristics that were associated with an unplanned pregnancy, with ambivalent feelings regarding the unplanned pregnancy and the co-occurrence of characteristics in women and men with unplanned pregnancy.

Results

Twenty nine percent of the pregnancies were unplanned. Logistic regression analyses showed that 42 of 44 studied predictors were significantly associated with unplanned pregnancy. The most important predictors were young age, migration background, lower educational level, lower household income, financial difficulties, being single, lower cognitive ability, drug use prior to pregnancy, having multiple sexual partners in the year prior to the pregnancy, younger age of first sexual contact and a history of abortion. Multinomial regression analyses showed that a Turkish or Moroccan background, Islamic religion, little financial opportunities, being married, having ≥3 children, high educational level, more mental health and social problems and older age of first sexual contact were associated with prolonged ambivalent feelings regarding pregnancy. Different combinations of characteristics were observed in the four clusters of women and men with unplanned pregnancy.

Conclusions

Many predictors are related with unplanned pregnancies, ambivalent feelings toward the pregnancy, and we identified very heterogeneous groups of women and men with unplanned pregnancies. This calls for heterogeneous measures to prevent unplanned pregnancies.

Do unwanted children face growth penalties in resource poor environments? Evidence from Roma Settlements in Serbia

In a high fertility context, research on the relationship between parental investment, unwanted births and child nutritional outcomes is limited. The implications may be especially relevant for children coming from the most disadvantaged backgrounds and at increased risk of nutritional deprivation. This study assessed the association between maternal investment, unwanted births disaggregated into mistimed and unwanted children, and child nutritional outcomes in a poor population of Serbian Roma. Multiple Indicator Cluster Surveys rounds 5 and 6 data for Serbian Roma settlements were used to account for the association between two measures of maternal investment: weight at birth and parity, and mistimed and unwanted children, and children height-for-age z-score (HAZ), weight-for-age z score (WAZ) and weight-for- height z-score (WHZ). The sample included 130 children aged 0-24 months. The child variables were age, gender, and birth order, while maternal independent variables included age, literacy and access to improved toilet facility as proxies for socioeconomic status. Children born with low birth weight (lower maternal investment in utero) face a significant deficit in terms of their nutritional outcomes, measured by HAZ and WAZ. The effect was aggravated for height if the child was unwanted while there was a positive relationship between access to improved toilet facility and WHZ. Unwanted children were of higher birth order, with older, higher parity mothers than mistimed children. Many of the Roma children may be at risk of undernutrition, however, Roma children who received lower maternal investment in utero, unwanted and living in poorest households may face additional risk.

Factors associated with contraceptive use among postpartum women with substance use disorder

OBJECTIVE

Rates of unintended pregnancy among women with substance use disorder (SUD) are much higher than the general reproductive-age population, suggesting lower rates of contraceptive use. This study aims to determine the prevalence of contraceptive use in postpartum women with SUD and identify factors associated with its use.

METHODS

This retrospective cohort study using electronic health record data from 2016 to 2019 included postpartum adult women with any SUD who received care at a high-risk pregnancy clinic (n = 353). The primary outcome was contraception utilization as identified using diagnosis and procedure codes. An adjusted multivariate logistic regression was used to evaluate the relationship between postpartum contraceptive use and sample characteristics.

RESULTS

Of the 353 postpartum women with SUD, contraceptive use was found in 128 (36.3%) women. Among the study population, the most commonly reported substance use disorders were nicotine use disorder (70.3%), opioid use disorder (51.3%), and cannabis use disorder (15.0%). Among those with opioid use disorder, 45.3% were found to be using medication for opioid use disorder (MOUD). Women who attended a postpartum visit had 2.23 times the odds of using contraception compared to women who did not (OR: 2.23, 95% CI: 1.20-4.15). Those using MOUD had 3.69 times the odds of using contraception compared to those who were not (OR: 3.69, 95% CI: 1.89-7.19). Overall, women who utilized contraception were more likely to be younger than 25, receiving MOUD, and participating in postpartum care.

CONCLUSIONS

Postpartum women with SUD are not using contraceptive methods and this is associated with a lack of appropriate healthcare interventions in the perinatal period, which can reduce the odds of receiving effective family planning services. Specialized whole-health interventions and policies to increase access to care for women with SUD should be developed.

Evaluation of the Desire to Avoid Pregnancy Scale in the UK: a psychometric analysis including predictive validity

OBJECTIVES

To evaluate the psychometric performance, including predictive validity, of a UK version of the Desire to Avoid Pregnancy (DAP) scale.

DESIGN

Prospective cohort study for psychometric evaluation.

SETTING

UK.

PARTICIPANTS

Women in the UK aged 15 years to menopause, who were not pregnant at the time of recruitment in October 2018, were eligible. 994 women completed the baseline survey and 90.2% of women eligible for the 12-month survey participated.

PRIMARY AND SECONDARY OUTCOME MEASURES

The DAP scale was assessed according to key measurement properties of validity (construct (structural and hypothesis testing) and criterion (predictive)), reliability (internal consistency using Cronbach's alpha and test-retest using intraclass correlation coefficients, ICC) and differential item functioning. Item response and classical test theory methods were used.

RESULTS

The scale was acceptable, understandable and showed good targeting with the full range of scores captured. Construct validity was demonstrated on hypothesis testing, with odds of contraceptive use increasing threefold with each increasing DAP point (range: 0-4). Eighty per cent of women with the lowest DAP score became pregnant within 12 months, compared with <1% of those with the highest DAP score. Reliability, both in terms of internal consistency (Cronbach's α 0.96) and test-retest (ICC 0.95), was excellent. Some tests of structural validity, in relation to model fit with the item-response model, were not met, and investigations suggest further exploration of the factor structure of the DAP is required in other samples. Item 5, regarding relationship with a partner, showed differential item functioning by age, number of children and relationship group.

CONCLUSIONS

The UK DAP is a valid and reliable measure of women's DAP and is highly predictive of pregnancy within the next 12 months. Further evaluations should continue the assessment of the factor structure and the performance of the item relating to the partner.

Learning Causal Effects From Observational Data in Healthcare: A Review and Summary

Causal inference is a broad field that seeks to build and apply models that learn the effect of interventions on outcomes using many data types. While the field has existed for decades, its potential to impact healthcare outcomes has increased dramatically recently due to both advancements in machine learning and the unprecedented amounts of observational data resulting from electronic capture of patient claims data by medical insurance companies and widespread adoption of electronic health records (EHR) worldwide. However, there are many different schools of learning causality coming from different fields of statistics, some of them strongly conflicting. While the recent advances in machine learning greatly enhanced causal inference from a modeling perspective, it further exacerbated the fractured state in this field. This fractured state has limited research at the intersection of causal inference, modern machine learning, and EHRs that could potentially transform healthcare. In this paper we unify the classical causal inference approaches with new machine learning developments into a straightforward framework based on whether the researcher is most interested in finding the best intervention for an individual, a group of similar people, or an entire population. Through this lens, we then provide a timely review of the applications of causal inference in healthcare from the literature. As expected, we found that applications of causal inference in medicine were mostly limited to just a few technique types and lag behind other domains. In light of this gap, we offer a helpful schematic to guide data scientists and healthcare stakeholders in selecting appropriate causal methods and reviewing the findings generated by them.

Making the financial case for immediate postpartum intrauterine device: a budget impact analysis

BACKGROUND

Clinical guidelines support inpatient postpartum intrauterine device insertion. However, inpatient placement remains infrequent, in part because of inconsistent private insurance reimbursement.

OBJECTIVE

The purpose of this study was to explore how the payer's costs and number of unintended pregnancies associated with a postpartum intrauterine device differed on the basis of placement timing.

STUDY DESIGN

Using a decision tree model and following a hypothetical cohort of people who intend to use an intrauterine device after their delivery, we conducted a cost analysis comparing the planned approach of inpatient vs outpatient postpartum insertion. Using a 2-year time horizon, the probability and cost estimates were derived from literature review. Our primary outcome was the total accrued costs to the payer. Secondarily, we examined the rates of early repeat pregnancy and sensitivity to estimates of key inputs, including the expulsion rates and the intrauterine device cost.

RESULTS

Although an inpatient intrauterine device placement's upfront costs were higher, the total cost of this approach was lower. Including the costs of managing expulsions and complications, our model suggests that for every 1000 people desiring a postpartum intrauterine device, the intended inpatient intrauterine device placement resulted in total cost savings of $211,100 and the prevention of 37 additional pregnancies compared with outpatient placement. The inpatient cost savings were superior to the outpatient savings, largely because of a known high proportion not returning for outpatient placement and the resulting higher number of unintended pregnancies among the patients desiring outpatient placement. In sensitivity analyses, we found that the total cost to the payer was sensitive to the probability of expulsion after immediate postpartum intrauterine device placement.

CONCLUSION

For beneficiaries desiring postpartum intrauterine device, payers are likely to save money by fully reimbursing inpatient intrauterine device placement rather than incentivizing placement at the frequently missed postpartum visit. These results support the financial case for private insurers to fully and separately reimburse (ie, "unbundle" from the single payment for delivery) inpatient postpartum intrauterine device placement.

Association of Prepregnancy Substance Use and Substance Use Disorders with Pregnancy Timing and Intention

Background: Limited research exists on the association between substance use disorders (SUDs) and dimensions of pregnancy intention. This study sought to examine the independent relationships between prepregnancy substance use and SUDs with pregnancy timing and intentions. Materials and Methods: Secondary analysis of data from three prenatal care sites in Connecticut, Massachusetts, and Michigan, 2016-2017. Associations were estimated using modified Poisson regression with robust error variance to calculate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs), controlling for relevant covariates. Results: The total sample size was 1115 women. Respectively, 61.1% and 15.5% of women used any substance in the 30 days prepregnancy or had any SUD in the past 12 months. After adjustment, any prepregnancy substance use was associated with a reduced likelihood of a well-timed (aPR 0.85; 95% CI: 0.77-0.93) and intended (aPR 0.80; 95% CI: 0.72-0.89) pregnancy; similarly, any SUD was associated with a reduced likelihood of a well-timed (aPR 0.66; 95% CI: 0.55-0.80) and intended (aPR 0.79; 95% CI: 0.67-0.93) pregnancy. Conclusions: Women with prepregnancy substance use or SUD have decreased prevalence of well-timed and intended pregnancies. Greater efforts are needed to address substance use and family planning in routine, well-woman, prenatal, and postpartum care.

Community Pharmacists' Knowledge, Willingness, and Readiness to Prescribe Oral Contraceptives in Saudi Arabia

Background: The role of community pharmacists (CPs) in various healthcare settings is well documented in the literature including providing safe and easy access to medications. Oral contraceptives (OCPs) are the most frequently used method of terminating unwanted pregnancies worldwide. Objective: This study aims to evaluate the Community pharmacist’s knowledge, willingness, and readiness to prescribe OCPs in Saudi communities in Saudi Arabia. Methods: This is across sectional, self-administered questionnaire-based study conducted between May and November 2021 in the central region of Saudi Arabia. The results were presented as frequencies and percentages. Chi-square tests were used to sort significant association between groups. Results: Out of 368 CPs who got the questionnaire, 347 completed (94.3%). Most of CPs were be-tween the ages of 25 and 35, with 76.9% working in chain pharmacies. Of the surveyed CPs, 45.5% had >24 months of experience in community pharmacies. 41.8% of them prescribed more than six prescriptions for OCPs/week. The patients’ safety (77.2%), physician’s resistance (54.5%), and CPs objection based on religious purposes (36.9%) and lack of time (29.7%) were the most commonly cited barriers among CPs. CPs who worked in chain pharmacies were significantly too busy (p = 0.038) to prescribe OCPs. Also, community pharmacists with experience of more than two years significantly agreed not to prescribe OCPs due to religious convictions (p = 0.009). Conclusion: The current study revealed that most of the CPs were knowledgeable about OCPs. Additionally, most of them were likely to prescribe oral contraceptives. We further suggest overcoming the barriers associated with contraceptives among CPs and providing sufficient training to improve the oral contraceptive prescriptions in CPs is needed.

Association of Medicaid Reimbursement for Immediate Postpartum Long-acting Reversible Contraception With Infant Birth Outcomes

IMPORTANCE

Together, preterm birth and low birth weight are the second-leading cause of infant mortality in the US and occur disproportionately among Medicaid-paid births and among the infants of Black birthing persons. In 2012, South Carolina's Medicaid program began to reimburse hospitals for immediate postpartum long-acting reversible contraception (LARC) separately from the global maternity payment.

OBJECTIVE

To examine the association between South Carolina's policy change and infant health.

DESIGN, SETTING, AND PARTICIPANTS

This population-based cohort study using a difference-in-differences analysis included individuals with a South Carolina Medicaid-paid childbirth between January 2009 and December 2015. Data were analyzed from December 2020 to July 2021.

EXPOSURES

Medicaid-paid childbirth after March 2012 in South Carolina hospitals that had implemented the policy.

MAIN OUTCOMES AND MEASURES

Immediate postpartum LARC uptake, subsequent birth within 4 years, subsequent short-interval birth, days to subsequent birth, subsequent preterm, and low-birth-weight birth within 4 years.

RESULTS

The study sample included 186 953 Medicaid-paid births between January 2009 and December 2015 in South Carolina (81 110 births from 2009 to 2011, 105 843 births from 2012 to 2015, and 46 414 births in exposure hospitals). The policy was associated with an absolute 5.6-percentage point (95% CI, 3.7-7.4) increase in the probability of receiving an immediate postpartum LARC overall, with significantly larger effects for non-Hispanic Black individuals than non-Hispanic White individuals (difference in coefficients 3.54; 95% CI, 1.35-5.73; P = .002). The policy was associated with a 0.4-percentage point (95% CI, -0.7 to -0.1) decrease in the probability of subsequent preterm birth and a 0.3-percentage point (95% CI, -0.7 to 0) decrease in the probability of subsequent low birth weight. No significant difference in the association between the policy and preterm birth or low-birth-weight birth between non-Hispanic Black and non-Hispanic White individuals was found. The policy was associated with a 0.6-percentage point (95% CI, -1.2 to -0.1) decrease in the probability of short-interval birth and a 27-day (95% CI, 11-44) increase in days to next birth among non-Hispanic Black individuals. The policy was associated with a significant decrease in the probability of a subsequent birth overall; however, confidence in this result is attenuated somewhat by nonparallel trends for this outcome before the policy change.

CONCLUSIONS AND RELEVANCE

Findings of this cohort study suggest policies increasing access to immediate postpartum LARC may improve birth outcomes but should be accompanied by other policy efforts to reduce inequity in these outcomes.

Early Sexual Debut and Neighborhood Social Environment in Latinx Youth

OBJECTIVES

To examine whether social aspects of the neighborhood environment are associated with early sexual initiation in a California agricultural community of predominantly Latinx adolescents.

METHODS

In a prospective cohort study of 599 eighth graders recruited from middle schools in Salinas, California (2015-2019), participants completed five interviews over 2 years. Social environment measures included neighborhood social dynamics (neighborhood disorder, social cohesion, and social network gang exposure); experiences of discrimination; and school connectedness. We estimated associations between baseline social environment and early sexual initiation (<15 years) using Poisson regression with robust standard errors. We compared contraceptive self-efficacy and attitudes by sexual initiation status using ANOVA.

RESULTS

Most youth were Latinx (94%) and age 13 (70%) at enrollment; 53% were female and 49% had a parent employed in agriculture. Additionally, 14% reported first vaginal sex before age 15. Neighborhood disorder (relative risk [RR], 1.13; 95% confidence interval [CI], 1.05-1.21), social network gang exposure (RR, 2.23; 95% CI, 1.49-3.33), and experiences of discrimination (RR, 1.67 [1-2 events versus none], 95% CI, 1.09-2.55; RR, 2.33 [3+ events versus none], 95% CI, 1.07-4.64) were associated with early sexual initiation. School connectedness was protective (RR, 0.44, 95% CI, 0.29-0.69). Youth who initiated sex before age 15 had more negative birth control attitudes and expressed lower motivation to use contraceptives.

CONCLUSIONS

Findings underscore opportunities to promote early adolescent sexual health through strengthening supportive and safe neighborhood environments with the promise of addressing disparities in unintended pregnancy and sexually transmitted infection rates in later adolescence.

Reproductive Coercion, Intimate Partner Violence, and Unintended Pregnancy Among Latina Women

Reproductive coercion (RC) describes a range of behaviors that restrict reproductive autonomy including pregnancy coercion, birth control sabotage, and controlling the outcome of a pregnancy. RC is associated with pregnancies that are mistimed and unwanted (i.e., unintended). Past research demonstrates that Latina women have higher risk for RC and for unintended pregnancy. This cross-sectional descriptive study with Latina women (n = 482) examined prevalence and risk factors for RC, evaluated the association of RC and unintended pregnancy among women with a past-year pregnancy, and explored use of safety and harm reduction strategies. A tablet survey was administered to women attending a community health center, between the ages of 15 and 45, who self-identified as Latina and who had a dating or sexual partner in the past year. Approximately one in six (16.8%) experienced past-year RC and risk factors included younger age (adjusted odds ratio [AOR] = 0.95, 95% confidence interval [CI] = [0.91, 1.00], p = .038) and concurrent intimate partner violence (IPV; AOR = 4.47, 95% CI = [2.06, 9.70], p < .001). IPV questions were specific to the partner involved with RC behaviors. For the 185 participants who reported a past-year pregnancy, RC was associated with lower pregnancy planning scores (β = -.27, 95% CI = [-0.41, -0.13], p < .001). The combination of experiencing RC and IPV appeared particularly potent in lowering pregnancy planning scores (β = -.15, 95% CI = [-0.29, 0.00], p = .052). Approximately 10.6% of participants engaged in harm reduction strategies, most commonly ending an unhealthy or abusive relationship (6.1%) and using less detectable methods of contraception so that partners would not find out (3.4%). The study articulates the risk of RC and its intersection with IPV and unintended pregnancy for Latina women. Providers working with racially and ethnically marginalized women have an important role in promoting safety and harm reduction strategies that include offering less detectable methods of contraception and support in leaving unhealthy and abusive relationships.

Do Pregnancy Intentions Matter? A Research Note Revisiting Relationships Among Pregnancy, Birth, and Maternal Outcomes

The prevention of unplanned or unintended pregnancies continues to be a cornerstone of U.S. reproductive health policy, but the evidence that such pregnancies cause adverse maternal and child outcomes is limited. In this research note, we examine these relationships using recent large-scale data and inverse propensity weights estimated from generalized boosted models. We find that pregnancy timing is related to maternal experience during pregnancy, but not to infant outcomes at birth-both of which are consistent with prior research. In an addition to the literature, we show that pregnancy timing is relevant for a number of maternal outcomes, such as the onset of depression and intimate partner violence, changes in smoking behavior, and receipt of medical care. These findings suggest that policy intended to improve infant welfare by preventing unintended pregnancies has little empirical support, but that policy focused on increasing reproductive autonomy and maternal well-being has the potential to improve outcomes.

Menstrual irregularity as a biological limit to early pregnancy awareness

US state legislatures have proposed laws to prohibit abortion once the earliest embryonic electrical activity is detectable (fetal “heartbeat”). On average, this occurs roughly 6 wk after the last menstrual period. To be eligible for abortion, people must recognize pregnancy very early in gestation. The earliest symptom of pregnancy is a missed period, and irregular menstrual cycles—which occur frequently—can delay pregnancy detection past the point of fetal cardiac activity. In our analysis of 1.6 million prospectively recorded menstrual cycles, cycle irregularity was more common among young women, Hispanic women, and women with common health conditions, such as diabetes and polycystic ovary syndrome. These groups face physiological limitations in detecting pregnancy before fetal cardiac activity. Restriction of abortion this early in gestation differentially affects specific population subgroups, for reasons outside of individual control.

Preconception Substance Use and Risk of Unintended Pregnancy: Pregnancy Risk Assessment Monitoring System 2016-17

OBJECTIVE

This study examined the association between preconception substance use and unintended pregnancy in a large, nationally representative sample of women.

METHODS

In this cross-sectional study, we used data from the Pregnancy Risk Assessment Monitoring System (PRAMS) comprising, 74,543women who had birth during 2016-17. Logistic regression was used to assess the independent association of unintended pregnancy overall and by subtypes to preconception substance use (smoking and other nicotine/tobacco use, alcohol consumption, and use of cannabis, illicit/recreational drugs) and specific medication including prescription opioids, antidepressants and over the counter pain relief.

RESULTS

Overall, 41% of pregnancies were unintended. Nearly 57% of participants reported alcohol consumption during the preconception period, with 32% indicating binge drinking, 17% reported preconception smoking, and 10% cannabis use. Unintended pregnancy was significantly associated with substance use, including smoking (adjusted odds ratio [AOR]:1.5, 95% confidence interval [CI]: 1.4-1.6); as well as the use of other nicotine/tobacco (AOR:1.4, 95% CI: 1.3-1.5); cannabis (AOR: 1.9, 95% CI: 1.5-2.3); illicit/recreational drugs (AOR:1.7, 95% CI: 1.2-2.4), prescription opioids (AOR:1.4, 95% CI: 1.02-1.9), and prescription antidepressants (AOR 1.8, 95% CI: 1.1-3.0). The likelihood of unintended pregnancy was significantly elevated with heavy smoking, heavy alcohol consumption, and binge drinking. Analyses by unintended pregnancy subtype yielded similar results.

CONCLUSIONS

Preconception substance use was significantly and positively associated with unintended pregnancy. Evidence-based interventions are needed addressing substance use behavior and effective contraceptive use to prevent unintended pregnancy and related adverse effects on maternal and child health.
