Pregnancy intentions-a complex construct and call for new measures

Unplanned births and their effects on maternal Health: Findings from the Constances Cohort

Unplanned births remain relatively common, even in regions with high contraceptive prevalence and accessible abortion services, such as contemporary France. Previous studies have shown that unplanned births can have numerous negative consequences for the well-being of mothers and children, including poorer maternal health behaviors, delayed and insufficient prenatal care, and depression during or immediately after pregnancy. However, these studies do not provide conclusive evidence on whether the observed outcomes are a consequence of unplanned births or of the conditions in which they likely occur. Furthermore, scant attention has been given to other dimensions of maternal well-being, such as physical health. This study uses longitudinal data from the French Constances Cohort and applies fixed-effects event study models to examine how women's self-rated general health and risk of depressive symptoms are affected in the years following an unplanned birth. Results show that women who had an unplanned birth reported a sudden, significant drop in their general health in the year following the birth, particularly among the youngest, while health outcomes following planned births showed a gradual, slight decrease over the time-period considered. The risk of depressive symptoms increased similarly after birth for both unplanned and planned births. This study contributes to the literature by using a longitudinally constructed measure of unplanned births based on pre-birth fertility intentions, rather than commonly used retrospective measures prone to ex post rationalization. It also distinguishes between unwanted and mistimed births while further examining their consequences on medium-term maternal health.

Cohort profile: the ADAPT study, a prospective study of pregnancy preferences, pregnancy, and health and well-being in the southwestern USA

PURPOSE

Significant methodological shortcomings limit the validity of prior research on pregnancy decision-making and the effects of 'unintended' pregnancies on people's health and well-being. The Attitudes and Decisions After Pregnancy Testing (ADAPT) study investigates the consequences for individuals unable to attain their pregnancy and childbearing preferences using an innovative nested prospective cohort design and novel conceptualisation and measurement of pregnancy preferences.

PARTICIPANTS

This paper describes the characteristics of the ADAPT Study Cohort, comprised of 2015 individuals aged 15-34 years, assigned female at birth, recruited between 2019 and 2022 from 23 health facilities in the southwestern USA.

FINDINGS TO DATE

The cohort was on average 25 years old. About 59% identified as Hispanic/Latine, 21% as white, and 8% as black, 13% multiracial or another race. Over half (56%) were nulliparous. About 32% lived in a household with income <100% of the federal poverty level. A significant minority (37%) reported a history of a depressive, anxiety or other mental health disorder diagnosis, and 30% reported currently experiencing moderate or severe depressive symptoms. Over one-quarter (27%) had ever experienced physical intimate partner violence, and almost half (49%) had ever experienced emotional abuse. About half (49%) had been diagnosed with a chronic health condition, and 37% rated their physical health as fair or poor. The 335 (17%) participants who experienced incident pregnancy over 1 year were similar to selected non-pregnant matched comparison participants in terms of age, racial and ethnic identity, and parity but were more likely to live with a main partner than comparison participants.

FUTURE PLANS

We will continue to follow participants who experienced incident pregnancy and non-pregnant comparison participants until 2026. Analyses will examine pregnancy decision-making and investigate differences in health and well-being by prepregnancy pregnancy desires and feelings after the discovery of pregnancy, offering new insights into the consequences of not attaining one's reproductive preferences.

Influence of Pregnancy Intention on Postpartum Contraceptive Choice at an Urban Academic Medical Center

OBJECTIVE

 This study aimed to describe postpartum contraception preferences in the context of pregnancy intention (PI).

STUDY DESIGN

 A prospective cohort study analyzing postpartum contraceptive choice (PCC) in 431 postpartum women who delivered at a single academic medical center. PCC in women with an unintended or mistimed pregnancy was compared to contraceptive choice in women with an intended pregnancy using the adapted National Survey of Family Growth categorization. Mistimed and unintended pregnancies were grouped for analysis. Generalized linear modeling estimated the relative influence of PI on PCC adjusting for maternal age, race, and parity.

RESULTS

 Nearly three out of four (71.9%) pregnancies were mistimed or unintended. These pregnancies were more likely in women who were non-Hispanic Black (62.3%), unmarried (86.3%), 18 to 24 years (51.3%), and insured by Medicaid or Medicare (82.1%), compared to women with an intended pregnancy, p-value <0.001. Women with mistimed or unintended pregnancy were 83% more likely to choose highly effective, user-independent methods compared to any other or no method, adjusted relative risk (aRR) = 1.83 (95% confidence interval [CI]: 1.36, 2.47), and more likely to desire voluntary sterilization, aRR = 2.70 (95% CI: 1.58, 4.59). Additionally, women with these pregnancies were 56% more likely to use user-independent methods compared to user-dependent methods, aRR = 1.56 (95% CI: 1.18, 2.06).

CONCLUSION

 Women with mistimed or unintended pregnancies are 83% more likely to choose highly effective postpartum contraception or voluntary sterilization, and thus initiatives are necessary to increase access and affordability to these methods before hospital discharge after delivery.

KEY POINTS

· Nearly three out of four pregnancies in this study were mistimed or unintended.. · Women with mistimed or unintended pregnancies are more likely to choose highly effective postpartum contraception or voluntary sterilization.. · Public health initiatives to improve access to family planning services and postpartum contraception, including surgery for bilateral tubal ligation before discharge from the hospital postdelivery, are important areas of focus to help attenuate the rates of unintended pregnancy in the United States..

A history of recurrent pregnancy loss is associated with increased perinatal complications, but not necessarily a longer birth interval: a population study spanning 18 years

STUDY QUESTION

Is there a difference in the time interval between the first and second live births among individuals with and without recurrent pregnancy loss (RPL)?

SUMMARY ANSWER

Primary RPL (two or more pregnancy losses before the first live birth) is associated with a shorter time interval between the first and second live births compared with individuals without RPL, but this association is reversed in patients with secondary RPL (RPL patients with no or one pregnancy loss before the first live birth).

WHAT IS KNOWN ALREADY

There is limited information regarding the ability to have more than one child for patients with RPL. Previous studies have investigated the time to live birth and the live birth rate from the initial presentation to clinical providers. Most of the previous studies have included only patients treated at specialized RPL clinics and thus may be limited by selection bias, including patients with a more severe condition.

STUDY DESIGN, SIZE, DURATION

We conducted a population-based retrospective cohort study of 184 241 participants who delivered in British Columbia, Canada, and had at least two recorded live births between 2000 and 2018. The aim was to study the differences in the time interval between the first and second live births and the prevalence of pregnancy complications in patients with and without RPL. Additionally, 198 319 individuals with their first live birth between 2000 and 2010 were studied to evaluate cumulative second live birth rates.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Among individuals with at least two recorded live births between 2000 and 2018, 12 321 patients with RPL and 171 920 participants without RPL were included. RPL was defined as at least two pregnancy losses before 20 weeks gestation. Patients with primary RPL had at least two pregnancy losses occurring before the first live birth, while patients with secondary RPL had no or one pregnancy loss before the first live birth. We compared the time interval from the first to second live birth in patients with primary RPL, those with secondary RPL, and participants without RPL using generalized additive models to allow for a non-linear relationship between maternal age and time interval between first and second live births. We also compared prevalence of pregnancy complications at the first and second live births between the groups using non-parametric Kruskal-Wallis H test and Fisher's exact test for continuous and categorical variables, respectively. We assessed the cumulative second live birth rates in patients with primary RPL and those without RPL, among participants who had their first live birth between 2000 and 2010. Cox proportional hazards model was used to estimate and compare hazard ratios between the two groups using a stratified modelling approach.

MAIN RESULTS AND THE ROLE OF CHANCE

The adjusted time interval between the first and second live births was the longest in patients with secondary RPL, followed by individuals without RPL, and the shortest time interval was observed in patients with primary RPL: 4.34 years (95% CI: 4.09-4.58), 3.20 years (95% CI: 3.00-3.40), and 3.05 years (95% CI: 2.79-3.32). A higher frequency of pregnancy losses was associated with an increased time interval between the first and second live births. The prevalence of pregnancy complications at the first and second live births, including gestational diabetes, hypertensive disorder of pregnancy, preterm birth, and multiple gestations was significantly higher in patients with primary RPL compared with those without RPL. The cumulative second live birth rate was significantly lower in patients with primary RPL compared with individuals without RPL.

LIMITATIONS, REASONS FOR CAUTION

This study may be limited by its retrospective nature. Although we adjusted for multiple potential confounders, there may be residual confounding due to a lack of information about pregnancy intentions and other factors, including unreported pregnancy losses.

WIDER IMPLICATIONS OF THE FINDINGS

The results of this study provide information that will help clinicians in the counselling of RPL patients who desire a second child.

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.

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.

Reproductive decision making in women with medical comorbidities: a qualitative study

BACKGROUND

A growing number of reproductive-age women in the U.S. have chronic medical conditions, increasing their risk of perinatal morbidity and mortality. Still, they experience unintended pregnancies at similar rates to low-risk mothers. We have limited understanding of how these individuals consider decisions about pregnancy and contraceptive use. The purpose of this study was to understand factors that influence reproductive decision-making among pregnant women with chronic medical conditions.

METHODS

We conducted 28 semi-structured interviews with pregnant women with pre-existing medical conditions admitted to a tertiary maternal hospital to examine factors influencing reproductive decision making. Maternal demographic characteristics, medical history, and pregnancy outcome data were obtained through participant surveys and abstraction from electronic health records. Interview transcripts were coded and analyzed using Dedoose® with both deductive and inductive content analysis.

RESULTS

Out of 33 eligible participants, 30 consented to participate and 28 completed interviews. The majority of participants identified as black, Christian, made less than $23,000 yearly, and had a variety of preexisting medical conditions. Overarching themes included: 1) Perceived risks-benefits of pregnancy, 2) Perceived risks-benefits of birth control, 3) Determinants of contraceptive utilization, and 4) Perceived reproductive self-agency. Contraception was viewed as acceptable, but with concerning physical and psychological side effects. Although some considered pregnancy as a health threat, more experienced pregnancy as positive and empowering. Few planned their pregnancies.

CONCLUSIONS

Preexisting health conditions did not significantly influence reproductive decision-making. Barriers to birth control use were generally based in patient value-systems instead of external factors. Interventions to improve uptake and use of birth control in this cohort should focus on improving care for chronic health conditions and influencing patient knowledge and attitudes toward contraception.

Pregnancy intention and preconception contraceptive behaviors and substandard prenatal care in France

OBJECTIVE

Evaluate the association between a combined measure of time-based pregnancy intention and preconception contraceptive behavior and suboptimal prenatal care.

POPULATION AND METHOD

Women delivering a live birth in all maternity units during one week in March 2016 were interviewed in the postpartum ward (N = 13,132). Multinomial logistic regression models were used to assess the association between the indicator of pregnancy intention and substandard prenatal care (late initiation of care and less than the recommended number of prenatal visits (<60% recommended)).

RESULTS

83.6% of women had timed pregnancies, 4.7% had mistimed pregnancies but discontinued contraception to conceive, 8.0% had mistimed pregnancies without discontinuing contraception to conceive and 3.7% had unwanted pregnancies. Women with timed pregnancies or mistimed pregnancies despite discontinuing contraception to conceive were more socially advantaged than those who had an unwanted pregnancy or a mistimed pregnancy without discontinuing contraception to conceive. 3.3% of women had a substandard number of prenatal visits and 2.5% had delayed prenatal care initiation. The adjusted odds ratios (aOR) of substandard prenatal visits were high among women with unwanted pregnancies (aOR=2.78; 95% confidence interval [1.91-4.05]) and women with mistimed pregnancies who had not discontinued contraception to conceive (aOR=1.69; [1.21-2.35]) compared to women with timed pregnancies. No difference was observed for women with mistimed pregnancies who discontinued contraception to conceive (aOR=1.22; [0.70-2.12]).

CONCLUSION

Using routinely collected information on preconception contraception allows a more nuanced assessment of pregnancy intentions that can help caregivers identify women at greater risk of substandard prenatal care.

Longitudinal study of pregnancy intention and its association with pregnancy occurrence among female sex workers in Benin and Mali

BACKGROUND

The intention of becoming pregnant has an evident impact on the prenatal and postnatal period. For female sex workers (FSWs) in West Africa, among whom pregnancies are frequent as are HIV and sexually transmitted infections, a better understanding of their pregnancy intention and its influence on pregnancy occurrence could help prevent unwanted pregnancies and adverse effects on wanted pregnancies.

METHODS

We recruited 330 FSWs in Benin and 322 in Mali and followed them for 12 months. We evaluated their pregnancy intention at recruitment and 6-month follow-up, using a multidimensional prospective measure that we developed. We assessed pregnancy occurrence with a pregnancy test and a retrospective questionnaire at 6 and 12 months. A Cox proportional hazard model was used to estimate the association between intention and pregnancy. We carried out an analysis to take losses to follow-up into account using the inverse of probability of censoring weights and a cluster analysis to corroborate that the multidimensional measure of pregnancy intention fitted the data.

RESULTS

407 FSWs were included in the first 6-month analysis and 284 at 12 months. Mean age was 30.9 years. The pregnancy intention distribution was similar between the two periods: 15.2% in the first period and 16.3% in the second had a positive intention. One out of four were ambivalent and almost 60% (57.7% and 56.3%) had a negative intention. For 38.2% of the FSWs, the intention changed between the two periods. The global incidence rate (to first event) was 19.1 pregnancies per 100 person-years. There was a borderline significant trend (p = 0.0529) of decreased pregnancy incidence with decreasing intention. Compared to positive intention, the adjusted hazard ratio (aHR) for ambivalent and negative intentions were 0.71 [95% confidence interval (95% CI) 0.32-1.60] and 0.46 (95% CI 0.21-1.01), respectively.

CONCLUSION

The level of pregnancy intention influences its occurrence among FSWs and nearly one out of six wants a baby despite working in the sex trade. Programmatically, early identification of these women could facilitate provision of quality antenatal and postnatal care. Given other health risks associated with sex work this care may decrease potential risks of adverse maternal, fetal and neonatal outcomes.

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.

Shared Decision-Making: The Way Forward for Postpartum Contraceptive Counseling

There are multi-level barriers that impact uptake of postpartum contraception and result in disparities, including clinical barriers such as provider bias. Fortunately, clinicians have direct control over their contraceptive counseling practices, and thus reducing structural barriers is actionable through high quality contraceptive counseling that equips patients with the knowledge and guidance they need to fulfill their reproductive desires. Yet, many commonly employed contraceptive counseling strategies, like One Key Question and WHO tiered contraceptive counseling, are not patient-driven, do not account for the important nuances of contraceptive choices, and are not focused specifically on the postpartum period. Given the history of eugenics and reproductive coercion in the US, supporting patient through their contraceptive decision-making process is especially vital. Additionally, contraceptive preferences vary based on patient-level factors and fluctuate over time and counseling should account for such differences. Shared contraceptive decision-making occurs when patients provide input on their values, desires, and preferences and clinicians share medical knowledge and evidence-based information without judgement. This approach is considered the most ethically sound form of counseling, as it maximizes patient autonomy. Shared decision-making also has clinical benefits, including increased patient satisfaction. In sum, shared contraceptive decision-making should be universally adopted to promote ethical, high-quality care and reproductive autonomy.

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.

Comparison of Pregnancy Preferences Preceding vs Year 1 of the COVID-19 Pandemic

Importance

Understanding how the COVID-19 pandemic affected people's desire to avoid pregnancy is essential for interpreting the pandemic's associations with access to reproductive health care and reproductive autonomy. Early research is largely cross-sectional and relies on people's own evaluations of how their desires changed.

Objective

To investigate longitudinal changes in pregnancy desires during the year before and the first year of the COVID-19 pandemic.

Design, Setting, and Participants

In this cohort study, participants reported their pregnancy preferences at baseline and quarterly for up to 18 months between March 2019 and March 2021. An interrupted time series analysis with mixed-effects segmented linear regression was used to examine population-averaged time trends. People were recruited from 7 primary and reproductive health care facilities in Arizona, New Mexico, and Texas. Participants were sexually active, pregnancy-capable people aged 15 to 34 years who were not pregnant or sterilized. Data analysis was performed from September 2021 to January 2022.

Exposures

Continuous time, with knots at the onset of the first (July 1, 2020, summer surge) and second (November 1, 2020, fall surge) COVID-19 cases surges in the Southwest.

Main Outcomes and Measures

Preferences around potential pregnancy in the next 3 months, measured using the validated Desire to Avoid Pregnancy (DAP) scale (range, 0-4, with 4 indicating a higher desire to avoid pregnancy).

Results

The 627 participants in the analytical sample had a mean (SD) age of 24.9 (4.9) years; 320 (51.0%) identified as Latinx and 180 (28.7%) as White. Over the year before the first case surge in the US Southwest in summer 2020, population-averaged DAP scores decreased steadily over time (-0.06 point per quarter; 95% CI, -0.07 to -0.04 point per quarter; P < .001). During the summer 2020 surge, DAP scores stopped declining (0.05 point per quarter; 95% CI, -0.03 to 0.13 point per quarter; change in slope, P < .001). During the fall 2020 surge, however, DAP scores declined again at -0.11 point per quarter (95% CI, -0.26 to 0.04 point per quarter; change in slope, P = .10). Participants aged 15 to 24 years and those who were nulliparous and primiparous experienced greater declines in DAP score before the summer surge, and greater reversals of decline between summer and fall 2020, than did those who were aged 25 to 34 years and multiparous.

Conclusions and Relevance

These findings suggest that the COVID-19 pandemic onset was associated with the stalling of a prior trend toward greater desire for pregnancy over time, particularly for people earlier in their reproductive lives.

The role of pregnancy acceptability in maternal mental health and bonding during pregnancy

BACKGROUND

Pregnancy is an important time for women's mental health and marks the foundations of the emerging bond between mother and baby. This study aimed to investigate the role of pregnancy acceptability and intendedness in maternal mental health and bonding during pregnancy.

METHODS

Data were collected from a community sample of 116 Australian pregnant women (M = 29.54, SD = 5.31) through a series of self-report questionnaires pertaining to mental health and antenatal bonding.

RESULTS

Lower pregnancy acceptability was correlated with higher depression, anxiety and total distress, lower physical and environmental quality of life and lower antenatal bonding. Women who reported their pregnancy was intended reported higher physical quality of life than those who reported their pregnancy was unintended. The relationship between total distress and antenatal bonding was moderated by women's degree of pregnancy acceptability (low versus high). For women with low acceptability, higher distress was associated with lower bonding, but there was no such association for women with high pregnancy acceptability. The moderation model examining associations between distress and pregnancy acceptability explained 15% of the variance in antenatal bonding scores.

CONCLUSION

Consideration of women's appraisal of their pregnancy acceptability may provide a valuable framework for identifying individuals who may be at risk for mental health and bonding difficulties.

Desire, acceptability, and expected resolution: A latent class analysis of current pregnancy orientation in the United States

BACKGROUND

Scant research has examined latent and contextual dimensions of pregnancy intentions, conventionally classifying unintended pregnancies as mistimed (wanted later) or unwanted (not wanted at all). Being at risk of mistimed pregnancy likely encompasses a broad spectrum of emotions and expectations regarding pregnancy and merits further exploration.

METHOD

Using a national sample from GfK's online KnowledgePanel of women aged 15-39 considered at risk of mistimed pregnancy in 2017 (n = 1278), we conducted a latent class analysis to assess underlying patterns of current pregnancy orientation using three items: pregnancy desire, pregnancy acceptability, and expected pregnancy resolution. As class structure varied by relationship status (serious or not), we stratified analyses by relationship status.

RESULTS

Among women in serious relationships, three classes emerged: "No," "Slightly okay," and "Acceptable." For those not in serious relationships, there were two classes: "Strong no" and "Ambiguous." Overall, the classes indicate varied patterns of wantedness, acceptability, and anticipated resolution to potential pregnancy.

CONCLUSIONS

This analysis reinforces that the construct of mistimed pregnancy is too restrictive to reflect the inherent diversity of prospective pregnancy orientation. The combination of relationship type as a grouping variable for stratified analyses, financial hardships' impact, and the overall effect of increasing age on increasing interest in pregnancy suggest the importance of locating pregnancy intentions within the broader reproductive life course. Scholars, clinicians, and public health programs should allow for multidimensionality of pregnancy perspectives, locate them within the broader life course, and acknowledge the potential impacts of stratified relationship formation on eventual pregnancy intentions.

Environmental factors in declining human fertility

A severe decline in child births has occurred over the past half century, which will lead to considerable population declines, particularly in industrialized regions. A crucial question is whether this decline can be explained by economic and behavioural factors alone, as suggested by demographic reports, or to what degree biological factors are also involved. Here, we discuss data suggesting that human reproductive health is deteriorating in industrialized regions. Widespread infertility and the need for assisted reproduction due to poor semen quality and/or oocyte failure are now major health issues. Other indicators of declining reproductive health include a worldwide increasing incidence in testicular cancer among young men and alterations in twinning frequency. There is also evidence of a parallel decline in rates of legal abortions, revealing a deterioration in total conception rates. Subtle alterations in fertility rates were already visible around 1900, and most industrialized regions now have rates below levels required to sustain their populations. We hypothesize that these reproductive health problems are partially linked to increasing human exposures to chemicals originating directly or indirectly from fossil fuels. If the current infertility epidemic is indeed linked to such exposures, decisive regulatory action underpinned by unconventional, interdisciplinary research collaborations will be needed to reverse the trends.

Getting Intentional about Intention to Use: A Scoping Review of Person-Centered Measures of Demand

In recent years, there has been much reflection on the measures used to assess and monitor contraceptive programming outcomes. The meaning and measurement of intention‐to‐use (ITU) contraception, however, has had less attention and research despite its widespread inclusion in many major surveys. This paper takes a deeper look at the meaning and measurement of ITU around contraception. We conducted a scoping review guided by the following questions: What is the existing evidence regarding the measurement of ITU contraception? What definitions and measures are used? What do we know about the validity of these measures? We searched databases and found 112 papers to include in our review and combined this with a review of the survey instruments and behavioral theory. Our review found growing evidence around the construct of ITU in family planning programming and research. However there are inconsistencies in how ITU is defined and measured, and this tends not to be informed by advances in behavioral theory and research. Further work is needed to develop and test measures that capture the complexity of intention, examine how intention differently relates to longer‐range goals compared to more immediate implementation, and demonstrate a positive relationship between ITU and contraceptive use.

["Risk it"-why women who do not intend to get pregnant do not use contraception : Results of the BZgA study "Women's lives 3. Family planning in women's lives"]

Hintergrund

Trotz allgemein bekannten Verhütungsmethoden und flächendeckendem Zugang zu Verhütungsmitteln lässt sich beobachten, dass Frauen in westlichen Industriegesellschaften auch bei fehlender Schwangerschaftsabsicht oftmals nicht verhüten und schwanger werden.

Ziel der Arbeit

Die in diesem Beitrag durchgeführten Analysen zielen darauf ab, die Verbreitung des Phänomens der Nichtanwendung von Verhütung für Deutschland einzuschätzen und ein besseres Verständnis für die Gründe zu gewinnen, warum Frauen eine unbeabsichtigte Schwangerschaft riskieren.

Material und Methoden

Anhand von quantitativen Befragungsdaten zu 17.400 Schwangerschaften und von 116 offenen qualitativen Interviews aus der im Auftrag der Bundeszentrale für gesundheitliche Aufklärung (BZgA) durchgeführten Studie „frauen leben 3. Familienplanung im Lebenslauf von Frauen“ sind Aussagen zur Verbreitung der Nichtverwendung von Verhütungsmethoden trotz fehlender Schwangerschaftsabsicht und zu den dahinterliegenden Gründen möglich.

Ergebnisse

Die angegebenen Gründe für die Nichtverwendung von Verhütung lassen sich 3 sehr unterschiedlichen Motivlagen zuordnen: a) Spielen mit einem Kinderwunsch, was von knapp einem Drittel genannt wird, b) individuelle und strukturelle Hürden, wie z. B. gesundheitliche Vorbehalte oder zu hohe Kosten, und c) irrtümliche Annahme, nicht schwanger werden zu können. Es zeigt sich, dass diese Motive je nach biografischer Situation unterschiedlich verbreitet sind.

Diskussion

Die Ergebnisse weisen auf die Notwendigkeit eines differenzierteren Verständnisses unbeabsichtigter Schwangerschaften und zwar sowohl in der Forschung als auch der Prävention hin.

Als Limitation und damit als Bedarf für künftige Forschungen erweist sich, dass im Rahmen der Studie der Einfluss des (Sexual‑)Partners auf das Verhütungsverhalten der Frauen und auf die Gewolltheit der Schwangerschaft anhand der erhobenen Daten nicht untersucht werden kann.

Male-female concordance in reported involvement of women in contraceptive decision-making and its association with modern contraceptive use among couples in rural Maharashtra, India

OBJECTIVE

Women's involvement in contraceptive decision-making increases contraceptive use and reduces unmet need, but study of this has been limited to women's self-reports. Less research is available examining couple concordance and women's involvement in contraceptive decision-making as reported by both men and women.

STUDY DESIGN

We carried out a cross-sectional study using data from rural India (N = 961 young married couples). Using multivariable regression we examined the association between concordance or discordance in spousal reports of wife's involvement in contraceptive decision-making and modern contraceptive use, adjusting for demographics, intimate partner violence, and contraceptive use discussion.

RESULTS

More than one third (38.3%) of women reported current modern contraceptive use. Report of women's involvement in contraceptive decision-making showed 70.3% of couples agreed that women were involved, jointly or alone (categorized as Concordant 1), 4.2% agreed women were not involved (categorized at Concordant 2), 13.2% had women report involvement but men report women were uninvolved (categorized as Discordant 1), and 12.2% had women report uninvolvement but men report that women were involved (categorized as Discordant 2). Discordant 2 couples had lower odds of modern contraceptive use relative to Concordant 1 couples (adjusted RR = 0.61, 95% CI 0.45-0.83). No other significant differences between Concordant 1 couples and other categories were observed.

CONCLUSION

One in four couples indicated discordance on women's involvement in contraceptive decision making, with Discordant 2 category having lower odds of contraceptive use. Couples' concordance in women's involvement in contraceptive decision-making offers a target for family planning research and interventions to better meet their needs.

Does the Impact of Motherhood on Women's Employment and Wages Differ for Women Who Plan Their Transition Into Motherhood?

Women's ability to control their fertility through contraception and abortion has been shown to contribute to improvements in education and employment. At the same time, their employment and wages decline substantially when they transition to motherhood. About one-third of births are unintended, and it is unknown whether the impact of motherhood on employment, hours, and wages is smaller for women who planned their transition into motherhood compared with those who did not. To explore this, we examine fixed-effects models that estimate labor market outcomes using panel data from the National Longitudinal Survey of Youth, 1979-2014. We estimate models for Black and White women and find that the relationship between motherhood and employment is significantly more negative among White women who plan their transition into motherhood than among those who have an unplanned first birth. Among those who remain employed, we find that those with a planned first birth work fewer hours and have lower wages relative to those with unplanned births. We do not find significant evidence that the association between motherhood and labor market outcomes differs by fertility planning among Black women. Prior research shows how women's choices are structurally constrained by sociocultural norms and expectations and by a labor market that may not readily accommodate motherhood. In this context, our findings may reflect differences in women's motherhood and employment preferences and their ability to act on those preferences. Our analysis also makes a novel contribution to the large body of research that associates unplanned births with negative outcomes.

The association of pregnancy control, emotions, and beliefs with pregnancy desires: A new perspective on pregnancy intentions

CONTEXT

Standard pregnancy intentions measures do not always align with how people approach pregnancy. Studies that have investigated beyond a binary framework found that those with "ambivalent" feelings towards pregnancy are less likely to use contraception consistently, but the reasons for this are unclear. We sought to gain a nuanced understanding of pregnancy desires, and how perceptions about pregnancy are associated with contraceptive use.

METHODS

We used non-probability quota sampling based on sex, age, and geographic region for a web-based survey of heterosexual men and women, aged 21-44 years, who could become pregnant/impregnate and were not currently pregnant (n = 1,477; 51% female). The survey was created using unique items informed by recent literature. Bivariate and multivariable analyses explored relationships between various perceptions about pregnancy with pregnancy desires categorized as: wanting a pregnancy, not wanting a pregnancy, and not trying but would be okay with a pregnancy. We conducted a sub-group analysis of those who were not trying but would be okay with a pregnancy (n = 460), using descriptive statistics to examine how consistent contraceptive use was associated with emotions and beliefs about avoiding pregnancy.

RESULTS

After adjustment, those who felt that pregnancy may not always be avoidable, but instead determined by fate/higher power, or a natural process that happens when it is meant to, were significantly more likely (aOR: 1.83, 95% CI: 1.05-3.36; aOR: 2.21, 95% CI: 1.29-3.76, respectively) to report not trying but being okay with pregnancy, whereas those with negative feelings about a pregnancy were less likely to feel okay about a pregnancy (aOR: 0.11, 95% CI: 0.08-0.15), versus not wanting a pregnancy. In the sub-group analysis, those who felt pregnancy was determined by fate/higher power or a natural process were more likely to report not using contraception consistently (70%, 68%, respectively).

CONCLUSIONS

Those who state they are not trying but would be okay with pregnancy may not use contraception consistently because of beliefs that pregnancy is predetermined. Our findings support less categorical and more multidimensional approaches to measuring fertility intentions, with important implications for reproductive health service provision.

Certainty and intention in pregnancy decision-making: An exploratory study

OBJECTIVE

Abortion is often characterized as an inherently difficult decision, despite research demonstrating high decision certainty among abortion patients. Minimal research has examined decision certainty among people planning to continue a pregnancy. We examined whether women seeking abortion experience lower decision certainty than those planning to continue pregnancies and whether certainty differs by pregnancy intendedness.

STUDY DESIGN

We administered the decisional conflict scale (DCS) to pregnant women (n = 149) at 8 U.S. primary and reproductive health clinics. Using Poisson regression models adjusted for sociodemographic and pregnancy characteristics, we evaluated differences in DCS scores (<25/100 vs ≥25/100) by pregnancy decision and whether pregnancy intention modified the effect of pregnancy decision on certainty.

RESULTS

Over one-half (58%) of respondents planned to have an abortion, 32% to continue the pregnancy, and 10% were unsure. DCS scores were low overall (median 9.4/100; IQR: 1.6, 25.0), indicative of high certainty, and the percentage scoring ≥25/100, reflecting any uncertainty, did not differ by pregnancy decision (23% abortion vs 19% continuing, p = 0.55). In a multivariable model, there was no statistically significant interaction between pregnancy decision (abortion vs continuing pregnancy) and intention. However, the predicted percentage reporting any uncertainty among respondents with intended pregnancies was comparable among those decided on abortion (13%) and continuing the pregnancy (16%). Among those with unintended pregnancies, these figures were 25% among those decided on abortion vs 36% among those continuing.

CONCLUSION

Levels of certainty about a pregnancy decision were high and appeared to depend more on whether the pregnancy was intended or unintended than on the pregnancy decision itself.

IMPLICATIONS

Similar levels of uncertainty among individuals who decided to have an abortion versus continue a pregnancy challenge the narrative that abortion is a particularly difficult medical and personal decision. The prevalence of some uncertainty among respondents continuing pregnancies suggests voluntary options counseling may be useful for some patients in prenatal care settings.

Association of Pregnancy Contexts with Depression and Low Social Support in Early Pregnancy

CONTEXT

Research into the relationship between pregnancy intention and perinatal depression or low social support is limited. Women's perspectives on pregnancy and their associations with perinatal depression could help in developing targeted efforts for screening and intervention.

METHODS

In 2014-2015, 161 women seeking pregnancy testing or abortion care at clinics in New Haven, Connecticut, were surveyed. They were asked about pregnancy context (intentions, planning, wantedness, desirability, timing and happiness), and the Edinburgh Depression Screen (EDS) and the Modified Kendler Social Support Index (MKSSI) were used to identify possible antenatal depression and low social support, respectively. Multivariable logistic regression analysis was employed to examine associations between pregnancy context and these outcomes.

RESULTS

On average, participants were 27 years old and at nine weeks' gestation. One-fifth reported a previous diagnosis of depression or anxiety, and 22% and 33% screened positive for depression (EDS scores of 13 or higher and 10 or higher, respectively); 52% received low social support (MKSSI score of 3.2 or less). Regression analysis found that pregnancies described as unintended, poorly timed or undesired were associated with depression at the higher cutoff (odds ratios, 3.2-4.5); all unfavorable pregnancy measures were associated with depression at the lower cutoff. Ambivalence regarding pregnancy timing, intention, wantedness and desirability was associated with increased odds of depression by either EDS score. Unplanned pregnancies and those about which the woman was ambivalent were associated with low social support.

CONCLUSIONS

Findings support the need to screen women for depression early in pregnancy and to integrate assessments of pregnancy context into the evaluation of potential risk factors.

Contraceptive use and the intention to become pregnant among women attending the Brazilian Unified Health System

OBJECTIVE

to analyze the use of contraceptive methods and the intention to become pregnant among women attending the Brazilian Unified Health System.

METHOD

a cross-sectional study conducted with 688 women aged 18-49 years old, attending the Family Health Strategy Facilities in the eastern part of the city of São Paulo, Brazil, who were awaiting medical or nursing consultation. Data were obtained through interviews with a structured instrument, allocated in tablets. The analysis was conducted with "strong desire to avoid pregnancy" as the dependent variable. Chi-square and multiple logistic regression were used, calculated in Stata 14.2.

RESULTS

56.5% used some contraceptive method, covariates of the strong desire to avoid pregnancy were marital status (OR=0.49; CI95%=0.33-0.74), parity - two and more children (OR=15.9; IC95%=4.29-59.1); and pregnancy planning - planned (OR=0.69; IC95%=0.73-0.94) and ambivalent (OR=2.94; IC95%=1.30-3.83). There was no statistical difference between the strong desire to avoid pregnancy and the type of contraceptive used.

CONCLUSION

women with a strong desire to avoid pregnancy used basically the same types of contraceptive methods as women in general, which shows that they have not been supported to achieve their reproductive preferences.

Asthma prevalence among women aged 18 to 44 in the United States: National health and nutrition examination survey 2001-2016

Objective: To provide updated prevalence estimates of asthma and asthma medication use for women of childbearing age in the United States.Methods: Using data from 11,383 women aged 18-44, including a subset of 1,245 pregnant women, enrolled in the National Health and Nutrition Examination Survey (2001-2016), we assessed the age-adjusted prevalence of self-reported diagnosed asthma. For women aged 18-44, we stratified by year, demographics, and other characteristics. Furthermore, we assessed asthma medication use among women aged 18-44 with asthma.Results: After age-adjustment, 9.9% (95% confidence interval (CI) 9.2%, 10.7%) of women aged 18-44 and 10.9% (95% CI 7.2%, 14.6%) of pregnant women reported having asthma. Asthma prevalence was highest in 2015-2016 (12.0% 95% CI 9.8%, 14.3%) and lowest in 2003-2004 (8.6% 95% CI 6.4%, 10.8%). Women aged 18-44 with Medicaid or State Children's Health Insurance Program insurance coverage (16.8% 95% CI 14.5%, 19.2%), obesity (14.4% 95% CI 12.9%, 15.8%), diabetes (18.7% 95% CI 12.1%, 25.2%), hypertension (16.6% 95% CI 14.2%, 19.0%), and current smokers (12.8% 95% CI 11.4%, 14.2%) had the highest asthma prevalence. Of women with asthma, 38.3% (95% CI 34.5%, 42.1%) reported using asthma medications in the past 30 days.Conclusions: Among women of childbearing ages, asthma burden varies across demographic and clinical characteristics and has increased in recent years.

Pregnancy intentions and contraceptive uptake after miscarriage

OBJECTIVE

To identify factors associated with contraceptive uptake among participants in a miscarriage management clinical trial.

STUDY DESIGN

We performed a secondary analysis of a multi-center, randomized controlled trial of medical management regimens for miscarriage between 5 and 12 completed weeks. Pregnancy intention was measured by patient report after miscarriage diagnosis. Participants were offered contraception in accordance with standard clinical care once their miscarriage was completed. We analyzed participants as a cohort and fit a multivariable model to describe demographic characteristics and pregnancy intentions independently associated with contraceptive uptake.

RESULTS

Of 244 participants with available contraceptive outcomes, 121 (50%) stated that this pregnancy was planned, and 218 (90%) stated that they had planned to continue the pregnancy to term. Ninety-seven participants (40%) initiated contraception: 33 (14%) selected a long-acting reversible method, 44 (18%) a short-acting reversible method, and 20 (8%) condoms or emergency contraception, while 147 (60%) declined contraception after miscarriage completion. In the multivariable model, unplanned pregnancy (aRR 2.13, 95% CI: 1.45-3.13) and lack of intention to continue the pregnancy (aRR 1.61, 95% CI: 1.18-2.20) were independently associated with contraceptive uptake. Of participants who declined contraception, 85 (57%) did so in order to conceive again. Nearly one-quarter of participants who declined contraception described the index pregnancy as unplanned, but after miscarriage planned to conceive a new pregnancy.

CONCLUSION

Patients with unplanned pregnancy who miscarried were twice as likely to initiate contraception as those with planned pregnancy, however pregnancy intentions sometimes changed after miscarriage.

IMPLICATIONS

Miscarriage management represents an important opportunity to clarify pregnancy goals and provide contraceptive counseling. Although unplanned pregnancy correlates with contraceptive uptake, we do not recommend using this clinically to predict contraceptive need. Future research should examine how best to measure pregnancy intention and its relationship to the experience of miscarriage.

Fertility Intentions and Clinical Care Attendance Among Women Living with HIV in South Africa

Poor HIV care retention impedes optimal treatment outcomes in persons living with HIV. Women trying to become pregnant may be motivated by periconception horizontal and vertical transmission concerns and thus more likely to attend HIV care visits than women not trying to conceive. We estimated the effect of fertility intentions on HIV care attendance over 12 months among non-pregnant, HIV-positive women aged 18-35 years who were on or initiating antiretroviral therapy in Johannesburg, South Africa. The percentage of women attending an HIV care visit decreased from 93.4% in the first quarter to 82.8% in the fourth quarter. Fertility intentions were not strongly associated with care attendance in this cohort of reproductive-aged women; however, attendance declined over time irrespective of childbearing plans. These findings suggest a need for reinforced efforts to support care engagement and risk reduction, including safer conception practices for women wishing to conceive.

Stability of Retrospective Pregnancy Intention Reporting Among Women with Unwanted Pregnancies in the United States

Objectives Retrospective assessment of pregnancy intention may be unreliable as women's perceptions of a past conception can change over time. We compared the stability of retrospective pregnancy intention reporting over 5 years among women who sought and either received, or were denied, an abortion. Methods We recruited women from 30 abortion facilities across the United States in 2008-2010. Participants, some who received abortions and others who were denied care because they presented beyond facilities gestational limits, were followed prospectively for 5 years (n = 827). At enrollment and semiannually from year-2 to year-5, women completed the London Measure of Unplanned Pregnancy (LMUP), a six-item measure (scored 0-12), regarding the index pregnancy. We used multivariable mixed-effects models to assess the stability of retrospective reports of index pregnancy intendedness and compared trajectories by group, accounting for site and participant clustering. Our hypotheses were that intention would tend towards "more intended" over time among women denied abortions, who carried the pregnancies to term, and remain stable among women who received the abortion. Results Baseline LMUP scores were low (mean: 2.8) and similar by study group. Scores increased among women denied the abortion by year-2 (from 2.9 to 3.5; p < 0.001) and were steady through year-5. For women having near-limit abortions, reported intentions were steady between baseline (mean: 2.7) and year-2 (2.8), and declined thereafter through year-5 (to 2.5; p < 0.001). Conclusions Women somewhat shifted their perceptions of their intentions in correspondence with the pregnancy outcome. Retrospective estimates may underestimate the degree to which births result from unintended pregnancy.

Exploring Multiple Dimensions of Young Women's Fertility Preferences in Malawi

INTRODUCTION

Standard survey measures of fertility preferences, such as the desire for and preferred timing of future births, do not capture the complexity of individuals' preferences. New research focuses on additional dimensions of emotions and expectations surrounding childbearing. Few quantitative studies, however, consider the influence of all three dimensions of fertility preferences concurrently.

METHODS

Using longitudinal survey data from the Tsogolo la Thanzi project (2009-2012) in Malawi, this study employed logistic regression analysis to investigate the influence of young women's emotions, expectations, and a standard measure of fertility preferences on pregnancy and modern contraceptive use.

RESULTS

Young women experienced high unmet need; across survey waves, over three-quarters of women who desired a child in more than 2 years were not currently using modern contraceptives and over three-quarters of women who thought a pregnancy in the next month would be bad news (garnered from a measure of emotions surrounding pregnancy) were not currently using modern contraceptives. In regression models including all three measures of fertility preferences, each was significantly associated with the likelihood of a future pregnancy. The standard measure and emotions measure were significantly associated with modern contraceptive use.

DISCUSSION

Emotions and expectations surrounding pregnancy and childbirth appear to be distinct and salient aspects of fertility preferences in addition to the standard measure. A better understanding of the multidimensional nature of fertility preferences will help individuals define and achieve their reproductive goals and obtain appropriate services. Furthermore, future research should incorporate new measures of fertility preferences into surveys internationally.

Pregnancy Intendedness by Maternal Disability Status and Type in the United States

CONTEXT

Societal views about sexuality and parenting among people with disabilities may limit these individuals' access to sex education and the full range of reproductive health services, and put them at increased risk for -unintended pregnancies. To date, however, no national population-based studies have examined pregnancy -intendedness among U.S. women with disabilities.

METHODS

Cross-sectional analyses of data from the 2011-2013 and 2013-2015 waves of the National Survey of Family Growth were conducted; the sample included 5,861 pregnancies reported by 3,089 women. The proportion of pregnancies described as unintended was calculated for women with any type of disability, women with each of five types of disabilities and women with no disabilities. Multivariate logistic regression analyses were conducted to examine the relationship of disability status and type with pregnancy intendedness while adjusting for covariates.

RESULTS

A higher proportion of pregnancies were unintended among women with disabilities than among women without disabilities (53% vs. 36%). Women with independent living disability had the highest proportion of unintended pregnancies (62%). In regression analyses, the odds that a pregnancy was unintended were greater among women with any type of disability than among women without disabilities (odds ratio, 1.4), and were also elevated among women with hearing disability, cognitive disability or independent living disability (1.5-1.9).

CONCLUSIONS

Further research is needed to understand differences in unintended pregnancy by type and extent of disability. People with disabilities should be fully included in sex education, and their routine care should incorporate discussion of reproductive planning.

Is Periconceptional Substance Use Associated with Unintended Pregnancy?

Background: To evaluate the relationship between periconceptional (period before and/or after conception) substance use and unfavorable pregnancy contexts, including unintended pregnancy.

Materials and Methods: This is a cross-sectional analysis of English- or Spanish-speaking women aged 16–44 years with pregnancies <24 weeks' gestation presenting to pregnancy testing clinics and enrolled between June 2014 and June 2015. Participants self-reported periconceptional substance use (tobacco, alcohol, marijuana, and other illicit substances during the 3 months before enrollment), and pregnancy “contexts,” including pregnancy intention, wantedness, planning, timing, desirability, and happiness. Multivariable logistic regression was performed adjusting for potential confounding variables.

Results: We enrolled 123 women, averaging 27 ± 6 years, and mean gestational age 7.5 ± 3.0 weeks. Most participants were black, non-Hispanic (37%), or Hispanic (46%), and chose to complete the study in English (69%). Sixty-five percent participants reported use of one or more substances during prior 3 months: alcohol (54%), tobacco (31%), and marijuana (21%). In multivariate analysis, periconceptional alcohol use was associated with increased odds of unintended or ambivalent pregnancy and unwanted or mixed feelings regarding pregnancy (odds ratios [OR] = 3.29, 95% confidence interval [CI] 1.08–10.08 and OR = 2.81, 95% CI 1.07–7.36, respectively). Weekly or daily tobacco use was associated with unhappiness about pregnancy (OR = 7.56, 95% CI 1.65–34.51) and undesired or unsure pregnancy (OR = 4.00, 95% CI 1.14–14.06).

Conclusions: Periconceptional alcohol or tobacco use demonstrates increased odds of specific unfavorable pregnancy contexts, including pregnancy described as undesired, unintended, unwanted, and unhappiness with pregnancy. Primary prevention of periconceptional substance use and the negative effects of alcohol and tobacco may be improved by increasing contraception access for women at risk for unfavorable pregnancy contexts.

Is Preconception Substance Use Associated With Unplanned or Poorly Timed Pregnancy?

OBJECTIVE

Unplanned and poorly timed pregnancies are associated with adverse maternal and neonatal outcomes. Further understanding of preconception substance use with unplanned and poorly timed pregnancy is warranted.

METHODS

Data were analyzed from a prospective study enrolling women early in pregnancy. Preconception tobacco, alcohol, marijuana, opioid, and cocaine use was ascertained. Participants reported whether their current pregnancy was planned and whether it was a good time to be pregnant. Multivariable logistic regression modeling generated risk estimates for preconception substance use, and pregnancy planning and timing, adjusting for confounders.

RESULTS

Overall, 37.2% reported unplanned pregnancy, 13.0% poorly timed pregnancy, and 39.0% reported either unplanned and/or poorly timed pregnancy. Within 6 months preconception, one-fifth (20.2%) reported nicotine cigarette use. In the month before conception, 71.8% reported alcohol use, 6.5% marijuana, and approximately 1% opioid or cocaine use. Multivariable analysis demonstrated preconception opioid use was associated with increased odds of poorly timed pregnancy (odds ratio [OR] 2.87, 95% confidence interval [CI] 1.03-7.99). Binge drinking the month before conception was associated with increased odds of poorly timed pregnancy and unplanned pregnancy (OR 1.75, 95% CI 1.01-3.05; and OR 1.68, 95% CI 1.01-2.79, respectively). Marijuana use 2 to 3 times in the month preconception was associated with increased risk of unplanned pregnancy, and unplanned and/or poorly timed pregnancy compared with nonuse (OR 1.78, 95% CI 1.03-3.08; and OR 1.79, 95% CI 1.01-3.17, respectively). Preconception tobacco or cocaine use was not associated with unplanned or poorly timed pregnancy following adjustment.

CONCLUSIONS

We demonstrate increased odds of unplanned or poorly timed pregnancy among women with preconception binge drinking, marijuana use, and opioid use; however, no association is observed with other substances after multivariable adjustment, including tobacco. Further research to evaluate high-level preconception substance use and substance disorders with pregnancy planning and timing is warranted. Focused efforts optimizing preconception health behaviors and reducing risk of unplanned or poorly timed pregnancy are needed.

Pregnancy happiness: implications of prior loss and pregnancy intendedness

Objective: This study aimed to examine the interaction between pregnancy loss and pregnancy intentions on women's happiness about a subsequent pregnancy.Background: Anxiety about prior loss persist for women, even during subsequent pregnancies. It is unclear from prior research, whether a prior pregnancy loss shapes attitudes towards and feelings about a subsequent birth.Methods: Using data from the 2002-2013 National Survey of Family Growth (NSFG), we used logistic regression analyses to explore the implications of a prior pregnancy loss for happiness about a subsequent pregnancy that ends in a live birth. We compared births classified as on-time, mistimed, unwanted, and ambivalent.Results: Births were more likely to be characterised as on-time if they occurred following a pregnancy loss, and women were less likely to report being happy about a conception if they were ambivalent about the conception and experienced a previous loss. Overall, pregnancy loss alone was not associated with lower levels of happiness about a subsequent birth.Conclusions: Pregnancy loss can be a highly distressing experience, women's happiness about a subsequent pregnancy is not reduced due to prior pregnancy loss. Future research should explore why women who were ambivalent about pregnancy reported lower levels of happiness following a loss.

Comparison of unintended pregnancy at 12 months between two contraceptive care programs; a controlled time-trend design

OBJECTIVES

To compare unintended pregnancy rates at 12 months between women receiving structured contraceptive counseling plus usual contraceptive care and women receiving structured contraceptive counseling, healthcare provider education and cost support for long-acting reversible contraceptive (LARC) methods.

STUDY DESIGN

Using a controlled time-trend study design, we first enrolled 502 women receiving structured contraceptive counseling in addition to usual care ("Enhanced Care") and subsequently enrolled 506 women receiving counseling plus healthcare provider education and cost support for LARC methods ("Complete CHOICE") at three federally qualified health centers (FQHCs). Cost support included funds to health centers for "on-the-shelf" LARC methods and no-cost LARC methods for uninsured women. Participants completed in-person baseline surveys and follow-up surveys by telephone at 3, 6 and 12 months. We used Kaplan-Meier survival function to estimate 12-month unintended pregnancy rates and Cox proportional-hazards regression to compare unintended pregnancy rates between the two groups. We imputed pregnancy outcomes for women lost to follow-up (9%) prior to 12 months.

RESULTS

"Complete CHOICE" participants were less likely to report an unintended pregnancy at 12 months compared to "Enhanced Care"; 5.3 vs. 9.8 pregnancies per 100 women-years (p=.01). After adjusting for confounders (recruitment site, race, age and federal poverty level), women in "Complete CHOICE" had a 40% lower risk of unintended pregnancy at 12 months (adjusted hazard ratio 0.60; 95% confidence interval 0.37-0.99).

CONCLUSIONS

Contraceptive provision that includes cost support and healthcare provider education in addition to patient counseling reduced unintended pregnancy at 12 months compared to counseling plus usual contraceptive care.

IMPLICATIONS

A program of contraceptive care that includes comprehensive counseling; healthcare provider education; cost support; and on-the-shelf, long-acting reversible contraception can reduce unintended pregnancy compared to contraceptive counseling in addition to usual health center care in the FQHC setting.

The Misclassification of Ambivalence in Pregnancy Intentions: A Mixed-Methods Analysis

CONTEXT

Researchers have developed various measures of pregnancy ambivalence in an effort to capture the nuance overlooked by conventional, binary measures of pregnancy intention. However, the conceptualization and operationalization of the concept of ambivalence vary widely and may miss the complexity inherent in pregnancy intentions, particularly for young people, among whom unintended pregnancy rates are highest.

METHODS

To investigate the utility and accuracy of current measures of pregnancy ambivalence, a mixed-methods study was conducted with 50 young women and their male partners in northern California in 2015-2016. Survey data were used to descriptively analyze six existing pregnancy ambivalence measures; in-depth interviews addressing pregnancy desires and plans were deductively coded and thematically analyzed to understand why some participants appeared to be ambivalent from the survey data when their interview responses suggested otherwise.

RESULTS

Eighty participants would be considered ambivalent by at least one measure. After assessment of the interview data, however, these measures were deemed to have misclassified almost all (78) participants. Qualitative analysis revealed several themes regarding misclassification: conflation of current pregnancy desires with expected postconception emotional responses; acceptability of an undesired pregnancy; tempering of survey responses to account for partners' desires; perceived lack of control regarding pregnancy; and, among participants with medical conditions perceived to impact fertility, subjugation of pregnancy desires in the interest of self-protection.

CONCLUSIONS

Current approaches to measuring pregnancy ambivalence may fail to capture the intricacies of pregnancy intentions and may be ineffective if they do not account for young people's experiences, especially when used to inform clinical practice, programs and policy.

Psychometric Evaluation of an Instrument to Measure Prospective Pregnancy Preferences: The Desire to Avoid Pregnancy Scale

BACKGROUND

Existing approaches to measuring women's pregnancy intentions suffer important limitations, including retrospective assessment, overly simple categories, and a presumption that all women plan pregnancies. No psychometrically valid scales exist to prospectively measure the ranges of women's pregnancy preferences.

MATERIALS AND METHODS

Using a rigorous construct modeling approach, we developed a scale to measure desire to avoid pregnancy. We developed 60 draft items from existing research, assessed comprehension through 25 cognitive interviews, and administered items in surveys with 594 nonpregnant women in 7 primary and reproductive health care facilities in Arizona, New Jersey, New Mexico, South Carolina, and Texas in 2016-2017. We used item response theory to reduce the item set and assess the scale's reliability, internal structure validity, and external validity. Items were included based on fit to a random effects multinomial logistic regression model (partial credit item response model), correspondence of item difficulty with participants' pregnancy preference levels, and consistency of each item's response options with overall scale scores.

RESULTS

The 14 final items covered 3 conceptual domains: cognitive preferences, affective feelings, and practical consequences. Items fit the unidimensional model, with a separation reliability of 0.90 (Cronbach α: 0.95). The scale met established criteria for internal validity, including correspondence between each item's response categories and overall scale scores. We found no important differential item functioning by participant characteristics.

CONCLUSIONS

A robust measure is available to prospectively measure desire to avoid pregnancy. The measure can aid in identifying women who could benefit from contraceptive care and research on less desired pregnancy.

Report of the Office of Population Affairs' expert work group meeting on short birth spacing and adverse pregnancy outcomes: Methodological quality of existing studies and future directions for research

BACKGROUND

The World Health Organization (WHO) recommends that women wait at least 24 months after a livebirth before attempting a subsequent pregnancy to reduce the risk of adverse maternal, perinatal, and infant health outcomes. However, the applicability of the WHO recommendations for women in the United States is unclear, as breast feeding, nutrition, maternal age at first birth, and total fertility rate differs substantially between the United States and the low- and middle-resource countries upon which most of the evidence is based.

METHODS

To inform guideline development for birth spacing specific to women in the United States, the Office of Population Affairs (OPA) convened an expert work group meeting in Washington, DC, on 14-15 September 2017 among reproductive, perinatal, paediatric, social, and public health epidemiologists; obstetrician-gynaecologists; biostatisticians; and experts in evidence synthesis related to women's health.

RESULTS

Presentations and discussion topics included the methodological quality of existing studies, evaluation of the evidence for causal effects of short interpregnancy intervals on adverse perinatal and maternal health outcomes, good practices for future research, and identification of research gaps and priorities for future work.

CONCLUSIONS

This report provides an overview of the presentations, discussions, and conclusions from the expert work group meeting.

Longitudinal patterns of unmet need for contraception among women living with HIV on antiretroviral therapy in South Africa

OBJECTIVES

Fertility intentions and contraceptive use are often not assessed in the context of clinical HIV care, representing a possible programming gap if women's family planning needs change over time. We aimed to identify longitudinal patterns of unmet need for contraception over a 12-month period among women living with HIV taking antiretroviral therapy (ART).

STUDY DESIGN

850 non-pregnant, HIV-positive women aged 18-35 on or initiating ART in Johannesburg, South Africa, were enrolled into a prospective cohort study in 2009-2010. Fertility intentions and contraceptive use were assessed during routine HIV care visits via an interviewer-administered questionnaire, and women were referred for on-site contraceptive counseling. We used group-based trajectory modeling to identify patterns of unmet need for contraception over 12 months, first in the entire population and then in a subset of recent ART initiators.

RESULTS

In the full population we identified four patterns of unmet need for contraception over one year. Half of the enrolled women were predicted to have a consistently high probability of unmet need, 22.9% a consistently low probability, 16.7% a decreasing probability, and 10.4% an increasing probability over time. Contraceptive method discontinuation and rapidly changing fertility intentions were the primary drivers of changing (increasing or decreasing) unmet need over follow-up. Results were similar in recent ART initiators.

CONCLUSIONS

Half of women were estimated to have a high probability of unmet need that persisted over time, and more than a quarter were estimated to experience patterns of changing unmet need over 12 months. Family planning needs should be assessed more regularly in HIV-positive women to prevent unintended pregnancies and support safer conception among women trying to conceive.

It's Not Planned, But Is It Okay? The Acceptability of Unplanned Pregnancy Among Young People

BACKGROUND

It is well-established that current measures of pregnancy intentions fail to capture the complexity of couples' lived experiences and decisions regarding reproductive decision making. Despite limitations, these measures guide programs, policy, and clinical practice. Herein, we explore prospective pregnancy acceptability, which captures whether individuals anticipate considering an unexpected pregnancy welcomed, manageable, or okay.

METHODS

Individual qualitative interviews were conducted with 50 young (ages 18-24 years) women and their male partners (N = 100) to elucidate prospective pregnancy desires and perspectives on pregnancy planning. Using a thematic approach, we analyzed data from a subsample (n = 88) of participants who did not currently desire a pregnancy.

RESULTS

Despite lack of pregnancy desire, 37 participants indicated that a pregnancy would be acceptable. Several themes emerged as reasons for pregnancy acceptability, including feeling prepared for children, relational stability, having knowledge of what it takes to parent, and taking a "whatever happens" approach toward pregnancy planning. Notably, a number of reasons for pregnancy acceptability were also described as reasons for lack of acceptability. For example, although many parents in the sample found pregnancy acceptable owing to their knowledge of the time and resources that raising children required, other parents found pregnancy unacceptable for this same reason.

CONCLUSIONS

Acceptability captures nuances of prospective views on pregnancy and what it means for young people's lives that current intentions language and framing often neglects. Additionally, acceptability may be a construct that resonates with the perspectives and lives of young people for whom the notion of active pregnancy planning is not salient.

Birth Planning and Women's and Men's Health in Malawi

Despite the frequency with which it occurs, we know little about unintended fertility in sub-Saharan Africa and even less about its implications for the health of the women and men who experience it. We use longitudinal data from southern Malawi to explore how young adults report on the planning of their births and to identify changes in their self-rated health and subjective well-being associated with having more- or less-planned births. Our data feature a comprehensive scale of pregnancy planning, the London Measure of Unplanned Pregnancy (LMUP), that extends beyond the conventional focus on timing-based pregnancy intentions to incorporate information about contraception, desires, intentions, partner discussion, and preconception preparations. Women and men have similar bimodal distributions on the LMUP, with the majority of births clearly unplanned or planned but a sizeable minority that falls in the middle. Change score models demonstrate that, for women, an unplanned birth is associated with a decline in self-rated health. In contrast, men whose births were ambivalently-planned experience a decline in subjective well-being. Our findings highlight the value of considering the full spectrum of birth planning and demonstrate the health consequences of unplanned fertility for both women and men in this sub-Saharan context.

Trends in Risk of Pregnancy Loss Among US Women, 1990-2011

BACKGROUND

Pregnancy loss can have physical and psychological consequences for women and their families. Though a previous study described an increase in the risk of self-reported pregnancy loss from 1970 to 2000, more recent examinations from population-based data of US women are lacking.

METHODS

We used data from the 1995, 2002, 2006-2010, 2011-2015 National Survey of Family Growth on self-reported pregnancy loss (miscarriage, stillbirth, ectopic pregnancy) among US women (15-44 years) who reported at least one pregnancy conceived during 1990-2011 that did not result in induced termination (n = 20 012 women; n = 42 526 pregnancies). Trends in the risk of self-reported pregnancy loss and early pregnancy loss (<12 weeks) were estimated, separately, by year of pregnancy conception (limited to 1990-2011 to ensure a sufficient sample of pregnancies for each year and maternal age group) using log-Binomial and Poisson models, adjusted for maternal- and pregnancy-related factors.

RESULTS

Among all self-reported pregnancies, excluding induced terminations, the risk of pregnancy loss was 19.7% and early pregnancy loss was 13.5% during 1990-2011. Risk of pregnancy loss increased by a relative 2% (rate ratio [RR] 1.02, 95% confidence interval [CI] 1.01, 1.02) per year in unadjusted models and 1% per year (RR 1.01, 95% CI 1.00, 1.02) during 1990-2011, after adjustment for maternal characteristics and pregnancy-related factors. In general, trends were similar for early pregnancy loss.

CONCLUSION

From 1990 to 2011, risk of self-reported pregnancy loss increased among US women. Further work is needed to better understand the drivers of this increase in reported pregnancy loss in the US.

Race and ethnicity may not be associated with risk of unintended pregnancy

OBJECTIVE

The objective was to use improved measures and methodology to investigate whether race and ethnicity are associated with unintended pregnancy.

STUDY DESIGN

Cross-sectional study of English- or Spanish-speaking women, aged 16-44, with pregnancies <24weeks' gestation recruited from pregnancy testing and abortion care sites in New Haven, CT, between June 2014 and June 2015. Participants completed self-assessments of race, ethnicity and multidimensional measures of pregnancy "context," including timing, intention, wantedness, desirability, happiness and planning (measured with the London Measure of Unplanned Pregnancy). Multivariable analysis was performed, adjusting for maternal demographics, language, recruitment site, substance use and medical conditions including history of depression.

RESULTS

Among 161 participants (mean age=27.2±6.6years), mean gestational age was 9±4.6weeks. Overall, 14% self-identified as White non-Hispanic, 37% Black non-Hispanic, 42% Hispanic and 7% multiracial. Most (85%) were unmarried, and 75% had at least one child. After adjustment, happiness about new pregnancies was more likely among Black non-Hispanic than White non-Hispanic women OR=5.66 (95%CI: 1.51-21.20). Neither race nor ethnicity was significantly associated with pregnancy intention, wantedness, planning, timing or desirability.

CONCLUSION

In a diverse cohort with multiple, antenatal measures of pregnancy context, neither race nor ethnicity is significantly associated with unintended pregnancy, as previous studies reported. Black non-Hispanic women were more likely to report happiness about new pregnancies than White non-Hispanic women. This study improves upon previous analyses that used retrospective and limited assessments of pregnancy intention, excluded women with miscarriages or abortions, and lacked adjustment for confounding.

IMPLICATIONS

Evaluation of multidimensional pregnancy contexts assessed antenatally is important and may capture the experiences of women more accurately, especially Black and Hispanic women.

Measuring health utility in varying pregnancy contexts among a diverse cohort of pregnant women

OBJECTIVE

To contribute to decision analysis by estimating utility, defined as an individual's valuation of specific health states, for different pregnancy contexts.

STUDY DESIGN

Cross-sectional analysis of data from pregnant women recruited at pregnancy testing clinics during June 2014-June 2015. Utility was measured using the visual analog scale (VAS), PROMIS GSF-derived utility, standard gamble (SG), and time-trade-off (TTO) approaches. Six dimensions of pregnancy context were assessed including: intention, desirability, planning, timing, wantedness, and happiness. Multivariable regression modeling was used to examine the associations between pregnancy context and utility while controlling for women's sociodemographic and health characteristics.

RESULTS

Among 123 participants with diverse characteristics, aged 27±6 years, with mean gestation of 7.5±3 weeks, few reported optimal pregnancy contexts. Mean utility of the pregnancy state varied across contexts, whether measured with VAS (0.28-0.91), PROMIS GSF-derived utility (0.66-0.75), SG (0.985-1.00) or TTO (0.9990-0.99999). The VAS-derived mean utility score for unintended pregnancy was 0.68 (95% CI 0.59, 0.77). Multivariable regression analysis demonstrated significant disutility of unintended pregnancy, as well as all other unfavorable pregnancy contexts, when measured by VAS. In contrast, PROMIS GSF-derived utility only detected a significant reduction in utility among ambivalent compared to wanted pregnancy, while SG and TTO did not show meaningful differences in utility across pregnancy contexts.

CONCLUSIONS

Unintended pregnancy is associated with significant patient-reported disutility, as is pregnancy occurring in other unfavorable contexts. VAS-based measurements provide the most nuanced measures of the utility for pregnancy in varying contexts.

IMPLICATIONS

Decision analyses, including assessments of the cost-effectiveness of pregnancy related interventions, should incorporate measures of the utility of pregnancy in various contexts.

"I Just Don't Know": An Exploration of Women's Ambivalence about a New Pregnancy

PURPOSE

We sought to examine how ambivalence manifests in women's lives after confirmation of a new pregnancy by exploring women's feelings, attitudes, and experiences regarding pregnancy intentions, the news itself, and related pregnancy decision making.

STUDY DESIGN

We recruited women aged 15 to 44 and at less than 24 completed weeks of gestational age from urban, walk-in pregnancy testing clinics in New Haven, Connecticut, from June 2014 to June 2015. We obtained quantitative and qualitative data via an enrollment survey and face-to-face, semistructured interviews, respectively. Transcripts were analyzed using framework analysis.

RESULTS

The sample included 84 women. Participants had a mean age of 26 years and were on average 7 weeks estimated gestational age at enrollment. Most identified as Black (54%) or Hispanic (20%), were unmarried (92%), and had at least one other child (67%). More than one-half (55%) described feelings of ambivalence regarding their current pregnancy. We identified ambivalence as a frequent and complex thread that represented distinct but overlapping perspectives about pregnancy: ambivalent pregnancy intentions, ambivalent response to new diagnosis of pregnancy, and ambivalence as uncertainty or conflict over pregnancy decision-making. Sources of ambivalence included relationship status, pregnancy timing, and maternal or fetal health problems.

CONCLUSIONS

This study improves on previous findings that focus only on ambivalence related to pregnancy intention or to decision making, and explores women's mixed, fluctuating, or unresolved feelings and attitudes about pregnancy before many participants had completed pregnancy decision making. Acknowledging and exploring sources of ambivalence regarding pregnancy may help health providers and policymakers to comprehensively support women with respect to both their experiences and reproductive goals.

Transitions in pregnancy planning in women recruited for a large prospective cohort study

STUDY QUESTION

Do the rates at which women transition among different intensities of pregnancy planning vary with age, marital status and race/ethnicity?

SUMMARY ANSWER

Rates of transition from low or moderate pregnancy probability groups (PPGs) to higher PPGs vary by age, marital status and race/ethnicity.

WHAT IS KNOWN ALREADY

The design of prospective studies of the effects of pre- and peri-conception exposures on fecundity, pregnancy and children's health is challenging because at any specific time only a small percentage of reproductive age women is attempting to conceive. To our knowledge, there has been no population-based, prospective study that repeatedly assessed pregnancy planning, which included women who were not already planning pregnancy at enrollment and whose ages spanned the female reproductive age range.

STUDY DESIGN, SIZE, DURATION

A longitudinal study was carried out that repeatedly assessed pregnancy probability in 12 916 women for up to 21 months from January 2009 to September 2010.

PARTICIPANTS/MATERIALS, SETTING, METHOD

We analyzed data from the National Children's Study Vanguard Study, a pilot study for a large-scale epidemiological birth cohort study of children and their parents. During the Vanguard Study, investigators followed population-based samples of reproductive age women in each of seven geographically dispersed and diverse study locations over time to identify when they sought to become pregnant, providing a unique opportunity to prospectively assess changes in pregnancy planning in a large sample of US women. At study entry and each follow-up contact, which occurred at 1, 3 or 6 month intervals depending on PPG, a questionnaire was used to assess behavior dimensions of pregnancy planning to assign women to low, moderate, high non-tryer and high tryer PPGs.

MAIN RESULTS AND THE ROLE OF CHANCE

Crude rates of pregnancy increased with higher assigned PPG, validating the utility of the instrument. The initial PPG and probabilities of transitioning from low or moderate PPG to higher PPG or pregnancy varied with age, marital status and race/ethnicity. Women aged 25 to <35 years had shorter times to transition to higher PPGs or to pregnant compared with women <25 years. Women who were not currently married had longer times to transition from any initial PPG to pregnant, high tryer or high non-tryer status than currently married women. Non-Hispanic Black (NHB) and Hispanic women had shorter time to transition from low or moderate to high non-tryer than non-Hispanic White (NHW) women. NHB women also had shorter time to transition from low to high tryer than NHW women. High tryers are more likely to be aged 25 to <30 years, to be married, and to be Hispanic, NHB or other race/ethnicity than women in the low PPG.

LIMITATIONS, REASONS FOR CAUTION

Loss to follow-up varied by age, marital status and race/ethnicity. Although weights were not developed for the Vanguard study, the self-weighting design minimizes the bias of unweighted analysis. Nonetheless, the SEs for some estimates may be under-estimated.

WIDER IMPLICATIONS OF THE FINDINGS

Our results show that demographic characteristics are strong predictors of women's behaviors toward pregnancy. The results further show that frequent follow-up assessments of pregnancy planning behavior in large numbers of women are required to recruit an unbiased sample of preconception women. These findings will be useful to investigators designing prospective studies of fecundability, pregnancy outcomes and children's health.

Pregnancy context and women's health-related quality of life

OBJECTIVE

The objective was to quantify the association of pregnancy context and health-related quality of life (HRQoL).

STUDY DESIGN

English- or Spanish-speaking women, aged 16-44, with pregnancies <24 weeks' gestation were enrolled in this cross-sectional study between June 2014 and June 2015. Participants completed self-assessments of pregnancy "context," including timing, intention, wantedness, desirability, happiness, and planning (measured with the London Measure of Unplanned Pregnancy). HRQoL was measured using the Patient Reported Outcomes Measurement Information System Global Short Form. Associations between measures of pregnancy context and HRQoL scores in the lowest tertile were examined using multivariable logistic regression to adjust for potential confounding variables.

RESULTS

We enrolled 161 participants (mean age=27.2±6.6 years). Only 14% self-identified as White, non-Hispanic; 42% Hispanic; 37% Black, non-Hispanic; and 7% multiracial. Most (79%) participants were unmarried, and 75% were parenting. Mean gestational age was 9±4.6 weeks. In unadjusted models, women reporting mixed feelings about wanting to have a baby, an undesired pregnancy or feeling unhappy about learning of their pregnancy more frequently had low mental and physical HRQoL compared to women reporting wanted, desired, happy pregnancies. Women with an unplanned pregnancy or pregnancy occurring at the wrong time also had lower physical HRQoL than women reporting pregnancies that were planned or happened at the right time. However, after multivariate adjustment, including history of depression, pregnancy contexts were not associated with low mental or physical HRQoL.

CONCLUSIONS

After adjusting for multiple confounders, pregnancy context is not significantly associated with HRQoL.

IMPLICATIONS

The focus on pregnancy intention in public health programs may not sufficiently assess multidimensional aspects of pregnancy context and may not align with patient-centered outcomes such as HRQoL.

Most Frequently Reported Prescription Medications and Supplements in Couples Planning Pregnancy: The LIFE Study

OBJECTIVE

To identify frequently reported prescription medications and supplements among couples planning pregnancy because there is a lack of descriptive information on these agents in women and men who are trying to conceive.

METHODS

Five hundred one couples enrolled in the Longitudinal Study of Infertility and the Environment, which took place between 2005 and 2009. Participants reported prescription medications as well as prescription and over-the-counter supplements used through interviews at study enrollment and through daily dairies during the 12-month follow-up. We identified prescription medications and supplements prospectively reported by ≥1% of women and men at baseline and from daily journal information grouped into 3-month preconception follow-up intervals while couples tried for pregnancy.

RESULTS

The 5 most reported prescription medications among women were levothyroxine (5.8%), cetirizine (2.6%), fluticasone (2.4%), escitalopram (1.8%), and fluoxetine (1.8%) and for men were lisinopril (2.0%), mometasone (2.0%), fexofenadine (1.8%), atorvastatin (1.6%), and montelukast (1.6%). The most reported supplements were multivitamins (63.3%, 43.5%) and fish oil (13.2%, 9.4%) for women and men, respectively, and prenatal vitamins (22.0%) for women. For women during the first 3 months of follow-up, prenatal vitamins (6.0%) and antibiotics (1.2%-2.6%) were among the most frequently started medications. During the next 3 months, clomiphene (4.5%) was the most frequently initiated medication.

CONCLUSIONS

Couples trying for pregnancy reported a variety of prescription medications and supplements, and they differed by gender. Preconception guidance should address medication and supplement use to avoid potential exposures associated with adverse reproductive and perinatal outcomes.
