Application of the Kessner and Kotelchuck prenatal care adequacy indices in a preterm birth population

Risk factors for late preterm and term stillbirth: A secondary analysis of an individual participant data meta-analysis

OBJECTIVE

Identify independent and novel risk factors for late-preterm (28-36 weeks) and term (≥37 weeks) stillbirth and explore development of a risk-prediction model.

DESIGN

Secondary analysis of an Individual Participant Data (IPD) meta-analysis investigating modifiable stillbirth risk factors.

SETTING

An IPD database from five case-control studies in New Zealand, Australia, the UK and an international online study.

POPULATION

Women with late-stillbirth (cases, n = 851), and ongoing singleton pregnancies from 28 weeks' gestation (controls, n = 2257).

METHODS

Established and novel risk factors for late-preterm and term stillbirth underwent univariable and multivariable logistic regression modelling with multiple sensitivity analyses. Variables included maternal age, body mass index (BMI), parity, mental health, cigarette smoking, second-hand smoking, antenatal-care utilisation, and detailed fetal movement and sleep variables.

MAIN OUTCOME MEASURES

Independent risk factors with adjusted odds ratios (aOR) for late-preterm and term stillbirth.

RESULTS

After model building, 575 late-stillbirth cases and 1541 controls from three contributing case-control studies were included. Risk factor estimates from separate multivariable models of late-preterm and term stillbirth were compared. As these were similar, the final model combined all late-stillbirths. The single multivariable model confirmed established demographic risk factors, but additionally showed that fetal movement changes had both increased (decreased frequency) and reduced (hiccoughs, increasing strength, frequency or vigorous fetal movements) aOR of stillbirth. Poor antenatal-care utilisation increased risk while more-than-adequate care was protective. The area-under-the-curve was 0.84 (95% CI 0.82-0.86).

CONCLUSIONS

Similarities in risk factors for late-preterm and term stillbirth suggest the same approach for risk-assessment can be applied. Detailed fetal movement assessment and inclusion of antenatal-care utilisation could be valuable in late-stillbirth risk assessment.

Maternal Dietary Diversity and Birth Weight in Offspring: Evidence from a Chinese Population-Based Study

Studies on the association between maternal dietary diversity and birth weight in offspring are limited, and the impact of such an adjustable factor on birth weight requires investigation to promote neonatal health. This study used data from a larger-scale population-based survey conducted in northwest China to evaluate the association of maternal dietary diversity with neonatal birth weight with a generalized estimating equation model. The results found that maternal dietary diversity was positively associated with neonate birth weight. Furthermore, a higher minimum dietary diversity for women (MDD-W) score during pregnancy was related to a lower risk of low birth weight (LBW) in offspring. The mothers with the highest MDD-W score had a 38% (OR = 0.62, 95% CI: 0.43-0.89) lower risk of LBW than those with the lowest score. Similarly, the mothers with the highest animal-based food dietary diversity score (DDS) had 39% (OR = 0.61, 95% CI: 0.38-0.98) lower risk of LBW in offspring compared with those with the lowest animal-based food DDS. Moreover, the ratio of animal-based food DDS to non-animal-based food DDS could play an important role in predicting neonate birth weight. In conclusion, increasing maternal dietary diversity would improve birth weight in offspring, especially by increasing the intake of animal-based foods among the Chinese population.

Prenatal and Birth Care of Roma Women

BACKGROUND

The reproductive health of Roma women has been poorly studied. It is important to determine the follow-up care received by Roma women from pregnancy to the first postpartum visit, together with neonatal outcomes, to improve prenatal care and maternal-child outcomes.

OBJECTIVE

The aim of this study was to examine differences in prenatal care and maternal-infant outcomes between Roma and non-Roma women.

METHODS

A retrospective longitudinal study was conducted in 122 pregnant women (28 Roma and 94 non-Roma women) recruited from seven primary care centers in three districts of Asturias (Spain). Sociodemographic variables, prenatal control, birth characteristics, feeding, and neonatal outcomes (gestational age, weight, and APGAR [appearance, pulse, grimace, activity, and respiration]) were collected from the electronic medical records. Prenatal care was assessed using three indices: the Kessner index, the Modified Adequacy of Prenatal Care Utilization Spanish Index, and an ad hoc index that considered adherence to the recommendations for pregnant women in Spain.

RESULTS

Compared with non-Roma women, advanced maternal age (≥35 years) and primigravida were less common among Roma women. Roma women visited the dentist less often, smoked more, and underwent group B streptococcus screening less frequently. No differences were found in the number of prenatal visits between Roma and non-Roma women. Consequently, there were no differences between the Kessner index and the Modified Adequacy of Prenatal Care Utilization Spanish Index. Using the ad hoc index, the non-Roma women more frequently had adequate prenatal visits. There were no differences in birth characteristics, type of feeding, and neonatal outcomes.

DISCUSSION

Overall, prenatal care was slightly worse in Roma women; however, this did not imply worse neonatal health outcomes. Both study groups had similar birth characteristics and immediate puerperium, including feeding.

Levels and determinants of quality antenatal care in Bangladesh: Evidence from the Bangladesh Demographic and Health Survey

BACKGROUND

Assessing the quality of antenatal care (ANC) is imperative for improving care provisions during pregnancy to ensure the health of mother and baby. In Bangladesh, there is a dearth of research on ANC quality using nationally representative data to understand its levels and determinants. Thus, the current study aimed to assess ANC quality and identify the sociodemographic factors associated with the usage of quality ANC services in Bangladesh.

METHODS

Secondary data analysis was conducted using the last two Bangladesh Demographic and Health Surveys (BDHSs) from 2014 and 2017-18. A total of 8,277 ever-married women were included in the analysis (3,631 from 2014 and 4,646 from 2017-18). The quality ANC index was constructed using a principal component analysis on the following ANC components: weight and blood pressure measurements, blood and urine test results, counselling about pregnancy complications and completion of a minimum of four ANC visits, one of which was performed by a medically trained provider. Multinomial logistic regression was used to determine the strength of the association.

RESULTS

The percentage of mothers who received all components of quality ANC increased from about 13% in 2014 to 18% in 2017-18 (p < 0.001). Women from the poorest group, those in rural areas, with no education, a high birth order and no media exposure were less likely to receive high-quality ANC than those from the richest group, those from urban areas, with a higher level of education, a low birth order and media exposure, respectively.

CONCLUSION

Although the quality of ANC improved from 2014 to 2017-18, it remains poor in Bangladesh. Therefore, there is a need to develop targeted interventions for different socio-demographic groups to improve the overall quality of ANC. Future interventions should address both the demand and supply-side perspectives.

Adverse birth outcomes in New York City women: Revisiting the Hispanic Paradox

In the United States, African American or non-Hispanic Black infants experienced worst birth outcomes whereas Hispanic and Asian infants have intermediate or similar outcomes compared with non-Hispanic white infants. The findings of better birth outcomes for Hispanic women have been coined the "Hispanic Paradox" given their low education, income, and access to care. New York City (NYC) has a great racial/ethnic diversity with implications for neighborhood racial/ethnic composition on birth outcomes by protecting women from psychosocial stress via social support that may buffer against racial/ethnic discrimination and/or racism. Data from 2012 to 2018 were used to examine the association of NYC women's race/ethnicity and neighborhood racial/ethnic minority composition with adverse birth outcomes (low birthweight [LBW], small for gestational age [SGA], preterm birth and infant mortality); and whether the association between mother's race/ethnicity and each birth outcome differed by neighborhood racial/ethnic composition. Multilevel logistic regression was used to control for the clustering of outcomes within neighborhoods. Black, Asian, and American Indian women have poorer birth outcomes than white women. Infants of Mexican American, Central American, and South American women were less likely to be of LBW whereas the opposite was true for infants of Cuban and other Hispanic women compared with infants of white women. When compared with white women, Mexican American, and South American women were less likely to have an SGA infant whereas Puerto Rican and other Hispanic women were more likely to have an SGA infant. All Hispanic women were more likely to have a preterm birth than white women whereas for infant mortality, greater odds of dying were observed for infants of Puerto Rican, Dominican, and other Hispanic women. Higher neighborhood racial/ethnic minority composition was associated with greater odds of having an adverse outcome. Finally, we observed heterogeneity of the associations between mother's race/ethnicity and birth outcomes by neighborhood racial/ethnic minority composition.

Evaluation of a telemedicine program managing high-risk pregnant women with pre-existing diabetes in Arkansas's Medicaid program

OBJECTIVE

We aim to evaluate the effects of the telemedicine program, High-Risk Pregnancy Program at University of Arkansas for Medical Sciences (UAMS), on health services utilization and medical expenditures among pregnant women with pre-existing diabetes and their newborns.

RESEARCH DESIGN AND METHODS

The study sample was selected from the Arkansas Medicaid claims linked to infant birth/death certificates and UAMS telemedicine records from 2013 through 2016. We used propensity score matching based on participants' characteristics to create three groups - UAMS telemedicine care, UAMS in-person care, and non-UAMS prenatal care. We compared inpatient and outpatient care services, medication use and caesarean section rates, severe maternal morbidity, infant mortality and preterm birth rates and medical expenditures.

RESULTS

The UAMS telemedicine group had fewer inpatient admissions (1.18 vs 1.31; 95% CI: -0.27, 0.00), lower insulin use rates (41.86% vs 59.88%; 95% CI: -29.00%, -7.05%) and lower maternal care expenditures ($7,846 vs $10,644; 95% CI: -$4,089, -$1,507) compared with the UAMS in-person care group. Women receiving UAMS telemedicine had more prenatal care visits (10.45 vs 8.57; 95% CI: -2.96, -0.81), higher insulin use rates (41.86% vs 26.74%: 95% CI: 4.63%, 25.60%) and similar maternal care expenditures ($7,846 vs $7,051), compared with those receiving non-UAMS in-person care. Caesarean section, severe maternal morbidity, and infant mortality rates were similar across the three groups.

CONCLUSION

UAMS telemedicine was associated with improved utilization of prenatal care among pregnant women with pre-existing diabetes. Telemedicine services did not differ from usual in-person services in clinical outcomes and medical expenditures.

Gestational Age of Delivery in Pregnancies Complicated by Diabetes

Background: The recommended gestational age to deliver pregnancies complicated by diabetes ranges from 34 to 39 weeks of gestation. The objective of this study was to determine the optimal gestational age for delivery of patients with diabetes to minimize perinatal death. Methods: We extracted a population-based cohort of singleton, nonanomalous infants of diabetic pregnancies from the Missouri birth registry for the period January 1, 1989 to December 31, 2005 and compared perinatal outcomes of planned deliveries at 37, 38, 39, and 40 weeks to expectant management. Planned deliveries were identified by induction or cesarean delivery without documented medical or obstetric indications. The primary outcome was perinatal death, defined as stillbirth or neonatal death within 28 days of birth. Secondary outcomes were independent stillbirth, independent neonatal death, and a composite adverse neonatal event of assisted ventilation >30 minutes, birth injury, seizures, or 5-minute Apgar score ≤3. Groups were compared using t test and chi-square as appropriate. Results: In 4,905 diabetic pregnancies reaching 37 weeks, 1,012 (20.6%) patients were insulin dependent. Overall, the risk of perinatal death at any gestational age examined was low (3/1,000 births or lower), as was the risk of the adverse perinatal outcome (<2%). When only patients who were insulin dependent were included in the analysis, the risk of perinatal death at any gestational age remained low at 6 per 1,000 births or fewer. Conclusion: Delivery as early as 37 weeks is reasonable for women who have diabetes, although the absolute risk of perinatal death is low at 37 to 39 weeks.

Exploration of the Effects of Rural Obstetric Unit Closures on Birth Outcomes in North Carolina

PURPOSE

Closures of rural labor and delivery (L/D) units have prompted national and state-based efforts to assess the impact on birth outcomes. This study explores local effects of L/D closures in rural areas of North Carolina (NC).

METHODS

This is a retrospective cohort study of birth outcomes of 4,065 women in 5 rural areas of NC with L/D unit closures between 2013 and 2017. Outcomes were abstracted from birth certificate data from the NC Vital Statistics Reporting System. Localized outcomes 1 year prior to L/D unit closure were compared with outcomes 1 and 2 years post closure, including: (1) birth location and demographics, (2) change in travel patterns for birth, and (3) birth outcomes, including rates of labor induction, cesarean deliveries, maternal morbidity, and neonatal outcomes.

FINDINGS

Before closures, 25%-56% of deliveries occurred outside county of residence. Commercially insured and college-educated women were more likely to deliver out-of-area. Closures increased travel distance to delivery hospital an average of 7-27 miles. In 2 areas, cesarean delivery rates decreased despite an increase in labor inductions. There was also variability between areas in prenatal care adequacy and breastfeeding.

CONCLUSIONS

We found that L/D unit closures in rural NC disproportionately affected women on Medicaid. The impact showed area-specific variability, highlighting effects potentially masked by statewide or national analyses. Implications for future L/D closures would be eased by regional coordination and planning to mitigate negative effects, and state and national policies should address the excess burden placed on vulnerable populations.

Exposure to Interpersonal Violence During Pregnancy and Its Association With Women's Prenatal Care Utilization: A Meta-Analytic Review

Inadequate prenatal care utilization has been proposed as a mechanism between exposure to violence during pregnancy and adverse maternal and fetal obstetric outcomes. Adequate prenatal care is important for identifying and treating obstetric complications as they arise and connecting pregnant women to supports and interventions as needed. There is some evidence that pregnant women experiencing relational violence may delay or never enter prenatal care, though this association has not been systematically or quantitatively synthesized. The present meta-analysis investigates the relationship between interpersonal violence during pregnancy and inadequate prenatal care utilization across two dimensions: (1) no prenatal care during gestation (k = 9) and (2) delayed entry into prenatal care (k = 25). Studies were identified via comprehensive search of 9 social science and health-related databases and relevant reference lists. Studies were included if (1) participants were human, (2) violence occurred in the context of an interpersonal relationship, (3) abuse occurred during pregnancy (including abuse within 12 months before the time of assessment during pregnancy), (4) the study was empirical, peer-reviewed, and included quantitative data, (5) prenatal care utilization data were available, (6) they were in English, and (7) they were not part of an intervention study. Results from random-effects models found that women abused during pregnancy were more likely to never enter care (odds ratio [OR] = 2.62, 95% confidence interval [CI] = [1.55, 4.42]) or to delay care (OR = 1.81, 95% CI [1.48, 2.23]). Sociodemographic, abuse-related, and methodological factors emerged as moderators. Practice, policy, and research implications are discussed.

Maternal exposure to low-to-medium altitude and birth outcomes: evidence from a population-based study in Chinese newborns

Despite high altitude was implicated in adverse birth outcomes, there remained a paucity of evidence on low-to-medium altitude effect. This study aimed to explore the association of low-to-medium altitude with birth outcomes. A population-based cross-sectional survey was performed using a stratified multistage random sampling method among women with their infants born during 2010-2013 in Northwestern China. Altitude was determined in meters based on the village or community of the mother's living areas. Birth outcomes involved birth weight, gestational age, and small for gestational age (SGA). Generalized linear models were fitted to investigate the association of altitude with birth outcomes. Moreover, the dose-response relationship between altitude and birth outcomes was evaluated with a restricted cubic spline function. A total of 27 801 women with their infants were included. After adjusting for potential confounders, every 100-m increase in the altitude was associated with reduced birth weight by 6.4 (95% CI -8.1, -4.6) g, the slight increase of gestational age by 0.015 (95% CI 0.010, 0.020) week, and an increased risk of SGA birth (odds ratio 1.03, 95% CI 1.02, 1.04). Moreover, there was an inversely linear relationship between altitude and birth weight (P for overall < 0.001 and P for nonlinear = 0.312), and a positive linear relationship between altitude and SGA (P for overall < 0.001 and P for nonlinear = 0.194). However, a nonlinear relationship was observed between altitude and gestational age (P for overall < 0.001 and P for nonlinear = 0.010). The present results suggest that low-to-medium altitude is possibly associated with adverse birth outcomes.

Quality assessment indicators in antenatal care worldwide: a systematic review

PURPOSE

To describe indicators used for the assessment of antenatal care (ANC) quality worldwide under the World Health Organization (WHO) framework and based on a systematic review of the literature.

DATA SOURCES

Searches were performed in MEDLINE, SciELO, BIREME and Web of Science for eligible studies published between January 2002 and September 2016.

STUDY SELECTION

Original articles describing women who had received ANC, any ANC model and, any ANC quality indicators were included.

DATA EXTRACTION

Publication date, study design and ANC process indicators were extracted.

RESULTS OF DATA SYNTHESIS

Of the total studies included, 69 evaluated at least one type of ANC process indicator. According to WHO ANC guidelines, 8.7% of the articles reported healthy eating counseling and 52.2% iron and folic acid supplementation. The evaluation indicators on maternal and fetal interventions were: syphilis testing (55.1%), HIV testing (47.8%), gestational diabetes mellitus screening (40.6%) and ultrasound (27.5%). Essential ANC activities assessment ranged from 26.1% report of fetal heart sound, 50.7% of maternal weight and 63.8% of blood pressure. Regarding preventive measures recommended by WHO, tetanus vaccine was reported in 60.9% of the articles. Interventions performed by health services to improve use and quality of ANC care, promotion of maternal and fetal health, and the number of visits to the ANC were evaluated in 65.2% of the studies.

CONCLUSION

Numerous ANC content indicators are being used to assess ANC quality. However, there is a need to use standardized indicators across countries and efforts to improve quality evaluation.

Influence of Acculturation on Risk for Gestational Diabetes Among Asian Women

Introduction

Asian women have a higher prevalence of gestational diabetes mellitus than women of other races/ethnicities. We aimed to compare the prevalence of gestational diabetes among Asian American women to other racial/ethnic groups and explore whether the higher occurrence of the disorder among Asian women can be explained by acculturation.

Methods

We conducted a population-based, cross-sectional study among 5,562 women who participated in the 2007 Los Angeles Mommy and Baby Study (LAMB) in Los Angeles County, California. All women included in this study had a live delivery in 2007 and did not have pre-pregnancy type I or II diabetes. We applied multivariate, weighted logistic regressions to compare gestational diabetes prevalence among racial/ethnic groups, adjusting for its known risk factors. We conducted mediation analysis to test whether the difference in prevalence across racial/ethnic groups could be explained by acculturation.

Results

Among the 5,562 women studied, the weighted prevalence of gestational diabetes was 15.5% among Asian American women, followed by 9.0% among non-Hispanic black women, 10.7% among Hispanic women, and 7.9% among non-Hispanic white women. Compared with non-Hispanic white women, Asian women had 2.44 (95% confidence interval [CI], 1.81–3.29; P < .001) times the odds of having gestational diabetes, independent of maternal age, education, marital status, income, prenatal care adequacy, prepregnancy BMI, and physical activity. Acculturation was negatively associated with having gestational diabetes (odds ratio [OR] = 0.93; 95% CI, 0.86–0.99) and explained 15.9% (95% CI, 11.38%–25.08%; P < .001) of the association between Asian race and the condition.

Conclusion

We found that Asian race was an independent risk factor for gestational diabetes, and higher acculturation may play a protective role against it in Asian American women.

Apgar score of 0 at 10 min and survival to 1 year of age: a retrospective cohort study in Washington state

OBJECTIVE

To determine 1-year survival in a cohort of newborns with an Apgar score of 0 at 5 and 10 min of age.

STUDY DESIGN

A retrospective cohort study of the Washington State Comprehensive Hospital Abstract Reporting System from 2005 to 2014.

RESULTS

Of 879,340 births, 199 (0.02%) had an Apgar score of 0 at 5 min, and 109 (0.01%) also had a score of 0 at 10 min. One-year survival was 46% for newborns with Apgar score of 0 at 5 and 10 min. One-year survival by gestational age was 4% for newborns <30 weeks, 38% for 30-35 weeks, and 67% for ≥36 weeks.

CONCLUSION

Survival at 1 year of age for newborns with an Apgar score of 0 at 5 and 10 min has improved, as compared with historic cohorts. Cautious optimism is warranted since morbidity-free survival could not be assessed.

Evaluating the quality of antenatal care and pregnancy outcomes using content and utilization assessment

Objective

To assess the adequacy of antenatal care (ANC) and its association with pregnancy outcomes using an approach that includes adequacy of both utilization and content.

Design

Retrospective cohort study.

Setting and Participants

Women attending ANC at public-funded primary health clinics where data were extracted from individual records.

Methods

Adequacy of utilization assessment was based on the concept of Adequacy of Prenatal Care Utilization index; adequacy of content assessed the recommended routine care received by the women according to local guidelines. Association between adequacy and pregnancy outcomes was examined using binary logistic regression.

Main Outcome Measures

Pregnancy outcomes included preterm birth and low birth weight.

Results

Sixty-three percent of women showed higher than recommended ANC utilization; 52% had <80% of recommended routine care content. Although not statistically significant, the odds of preterm birth was lower among women with adequate level of utilization compared with inadequate (adjusted odds ratios (aOR) = 2.34, 95% confidence interval (CI) 0.45-12.16) and intensive levels (aOR = 3.27, 95% CI 0.73-14.60). Regarding adequacy of content, women who received inadequate level of care content were associated with higher prevalence of preterm birth (aOR = 3.69, 95% CI 1.60-8.55).

Conclusion

The study shows inadequate content is associated with higher prevalence of preterm birth and suggests that inadequate utilization increases the risk of preterm birth. It demonstrates the relevance of using both utilization and content assessment in evaluating quality of ANC. Further studies are encouraged to review the methods used.

Attendance at prenatal care and adverse birth outcomes in China: A follow-up study based on Maternal and Newborn's Health Monitoring System

OBJECTIVE

to evaluate the independent association between attendance at prenatal care and adverse birth outcomes in China, measured either as the occurrence of preterm birth or low birth weight.

DESIGN

a follow-up study.

SETTING

the data was collected from maternal and newborn's health monitoring system at 6 provinces in China.

PARTICIPANTS

all pregnant women registered in the system at their first prenatal care visit. We included 40152 registered pregnant women who had delivered between October 2013 and September 2014.

MEASUREMENTS

attendance at prenatal care was evaluated using Kessner index. χ² tests were used to examine the correlations between demographic characteristics and preterm birth or low birth weight. The associations between attendance at prenatal care and birth outcomes were explored using multilevel mixed-effects logistic regression models.

FINDINGS

the prevalence for preterm birth and low birth weight was 3.31% and 2.55%. The null models showed region clustering on birth outcomes. Compared with women who received adequate prenatal care, those with intermediate prenatal care (adjusted OR 1.62, 95%CI 1.37-1.92) or inadequate prenatal care (adjusted OR 2.78, 95%CI 2.24-3.44) had significantly increased risks for preterm birth, and women with intermediate prenatal care (adjusted OR 1.31, 95%CI 1.10-1.55) or inadequate prenatal care (adjusted OR 1.70, 95%CI 1.32-2.19) had significantly increased risks for low birth weight. We found very significant dose-response patterns for both preterm birth (p-trend<0.001) and low birth weight (p-trend = 0.001).

KEY CONCLUSIONS AND IMPLICATION FOR PRACTICE

This study shows that attendance at prenatal care in China has independent effects on both preterm birth and low birth weight. Appropriate timing and number of prenatal care visits can help to reduce the occurrence of preterm birth or low birth weight.

Association between prenatal care utilization and risk of preterm birth among Chinese women

It is recognized that prenatal care plays an important role in reducing adverse birth. Chinese pregnant women with medical condition were required to seek additional health care based on the recommended at least 5 times health care visits. This study was to estimate the association between prenatal care utilization (PCU) and preterm birth (PTB), and to investigate if medical conditions during pregnancy modified the association. This population-based case control study sampled women with PTB as cases; one control for each case was randomly selected from women with term births. The Electronic Perinatal Health Care Information System (EPHCIS) and a questionnaire were used for data collection. The PCU was measured by a renewed Prenatal Care Utilization (APNCU) index. Logistic regression models were used to estimate odds ratios (OR) and the 95% confidence interval (95% CI). Totally, 2393 women with PTBs and 4263 women with term births were collected. In this study, 695 (10.5%) women experienced inadequate prenatal care, and 5131 (77.1%) received adequate plus prenatal care. Inadequate PCU was associated with PTB (adjusted OR: 1.41, 95% CI: 1.32-1.84); the similar positive association was found between adequate plus PCU and PTB. Among women with medical conditions, these associations still existed; but among women without medical conditions, the association between inadequate PCU and PTB disappeared. Our data suggests that women receiving inappropriate PCU are at an increased risk of having PTB, but it does depend on whether the woman has a medical condition during pregnancy.

Immediate postpartum glycemic control and risk of surgical site infection

OBJECTIVE

Nearly one-third of all births in the United States in 2013 were by cesarean delivery, with 6% complicated by diabetes. The purpose of this study was to correlate immediate postoperative hyperglycemia with wound morbidity in diabetic women who underwent cesarean delivery.

METHODS

This retrospective case-control study was performed at UC Irvine Health and Miller Women's & Children's Hospital Long Beach between 2009 and 2015. Subjects included women with at least Class B diabetes mellitus who underwent cesarean birth. Fasting and postprandial blood glucose levels (BGL) were recorded daily during postoperative days one through four. Outcomes included abscess formation, cellulitis, wound separation, fascial dehiscence, hospital readmission, secondary wound closure, antibiotic treatment, and a composite of the above.

RESULTS

Outcomes were evaluated for 176 subjects. Twenty-nine experienced wound complications. Women readmitted for wound complications and those with composite morbidity experienced significantly higher mean fasting BGL, however, BGL during the immediate postoperative setting were not predictive of wound morbidity.

CONCLUSION

In our cohort of diabetic women who underwent cesarean delivery, immediate postoperative hyperglycemia was not associated with wound morbidity.

Anatomy of Good Prenatal Care: Perspectives of Low Income African-American Women on Barriers and Facilitators to Prenatal Care

BACKGROUND

Although early, consistent prenatal care (PNC) can be helpful in improving poor birth outcomes, rates of PNC use tend to be lower among African-American women compared to Whites. This study examines low-income African-American women's perspectives on barriers and facilitators to receiving PNC in an urban setting.

METHODS

We conducted six focus groups with 29 women and individual structured interviews with two women. Transcripts were coded to identify barriers and facilitators to obtaining PNC; codes were reviewed to identify emergent themes.

RESULTS

Barriers to obtaining PNC included structural barriers such as transportation and insurance, negative attitudes towards PNC, perceived poor quality of care, unintended pregnancy, and psychosocial stressors such as overall life stress and chaos. Facilitators of PNC included positive experiences such as trusting relationships with providers, respectful staff and providers, and social support.

CONCLUSIONS

Findings suggest important components in an ideal PNC model to engage low-income African-American women.

Factors associated with the quality of prenatal care: an approach to premature birth

OBJECTIVETo assess the quality of prenatal care in mothers with premature and term births and identify maternal and gestational factors associated with inadequate prenatal care.METHODCross-sectional study collecting data with the pregnant card, hospital records and interviews with mothers living in Maringa-PR. Data were collected from 576 mothers and their born alive infants who were attended in the public service from October 2013 to February 2014, using three different evaluation criteria. The association of prenatal care quality with prematurity was performed by univariate analysis and occurred only at Kessner criteria (CI=1.79;8.02).RESULTSThe indicators that contributed most to the inadequacy of prenatal care were tests of hemoglobin, urine, and fetal presentation. After logistic regression analysis, maternal and gestational variables associated to inadequate prenatal care were combined prenatal (CI=2.93;11.09), non-white skin color (CI=1.11;2.51); unplanned pregnancy (CI=1.34;3.17) and multiparity (CI=1.17;4.03).CONCLUSIONPrenatal care must follow the minimum recommended protocols, more attention is required to black and brown women, multiparous and with unplanned pregnancies to prevent preterm birth and maternal and child morbimortality.

Reassessing the impact of smoking on preeclampsia/eclampsia: are there age and racial differences?

OBJECTIVE

To investigate the association between cigarette use during pregnancy and pregnancy-induced hypertension/preeclampsia/eclampsia (PIH) by maternal race/ethnicity and age.

METHODS

This retrospective cohort study was based on the U.S. 2010 natality data. Our study sample included U.S. women who delivered singleton pregnancies between 20 and 44 weeks of gestation without major fetal anomalies in 2010 (n = 3,113,164). Multivariate logistic regression models were fit to estimate crude and adjusted odds ratios and the corresponding 95% confidence intervals.

RESULTS

We observed that the association between maternal smoking and PIH varied by maternal race/ethnicity and age. Compared with non-smokers, reduced odds of PIH among pregnant smokers was only evident for non-Hispanic white and non-Hispanic American Indian women aged less than 35 years. Non-Hispanic Asian/Pacific Islander women who smoked during pregnancy had increased odds of PIH regardless of maternal age. Non-Hispanic white and non-Hispanic black women 35 years or older who smoked during pregnancy also had increased odds of PIH.

CONCLUSION

Our study findings suggest important differences by maternal race/ethnicity and age in the association between cigarette use during pregnancy and PIH. More research is needed to establish the biologic and social mechanisms that might explain the variations with maternal age and race/ethnicity that were observed in our study.

Measuring adequacy of prenatal care: does missing visit information matter?

BACKGROUND

Kotelchuck's Adequacy of Prenatal Care Utilization (APNCU) Index is frequently used to classify levels of prenatal care. In the Finger Lakes Region (FLR) of upstate New York, prenatal care visit information late in pregnancy is often not documented on the birth certificate. We studied the extent of this missing information and its impact on the validity of regional APNCU scores.

METHODS

We calculated the "weeks between" a mother's last prenatal care visit and her infant's date of birth. We adjusted the APNCU algorithm creating the Last Visit Adequacy of Prenatal Care (LV-APNC) Index using the last recorded prenatal care visit date as the end point of care and the expected number of visits at that time. We compared maternal characteristics by care level with each index, examining rates of reclassification and number of "weeks between" by birth hospital. Stuart-Maxwell, McNemar, chi-square, and t-tests were used to determine statistical significance.

RESULTS

Based on 58,462 births, the mean "weeks between" was 2.8 weeks. Compared with their APNCU Index score, 42.4 percent of mothers were reclassified using the LV-APNC Index. Major movement occurred from Intermediate (APNCU) to Adequate or Adequate Plus (LV-APNC) leaving the Intermediate Care group a more at-risk group of mothers. Those with Adequate or Adequate Plus Care (LV-APNC) increased by 31.6 percent, surpassing the Healthy People 2020 objective.

CONCLUSIONS

In the FLR, missing visit information at the end of pregnancy results in an underestimation of mothers' prenatal care. Future research is needed to determine the extent of this missing visit information on the national level.

The relationship between antenatal care and preterm birth: the importance of content of care

BACKGROUND

Antenatal care can play an important role in the prevention of preterm birth. Evaluation of antenatal care is usually based on the number of visits rather than the content of care, using tools such as the Adequacy of Prenatal Care Use index. This article presents an analysis of the relation between specific elements of antenatal care and the risk of preterm birth compared with considering the number of visits only.

METHODS

A prospective cohort study was conducted in the Brussels Metropolitan Region. In all, 333 women were consecutively recruited at the beginning of their antenatal care trajectory and followed until birth. Information on timing and content for every visit was recorded by structured interview. A new tool was developed to measure the antenatal care trajectory, which included Content and Timing of care in Pregnancy (CTP). Odds ratios (OR) (adjusted and unadjusted) for preterm birth were calculated for the Adequacy of Prenatal Care Use and CTP model.

RESULTS

The number of visits alone was not associated with preterm birth. In contrast, a significant association was found between the content and timing of care and preterm birth. Compared with the CTP lowest ('inadequate') category, women in the CTP 'sufficient' (OR 0.30; 95% CI 0.09-0.94) and CTP 'appropriate' (OR 0.21; 95% CI 0.06-0.68) category had a lower risk.

CONCLUSIONS

This study suggests that measurement of the content and timing of care of antenatal care using the new CTP tool is a better assessment of the risk of preterm birth than assessment of the number of antenatal visits alone.

The development and application of a new tool to assess the adequacy of the content and timing of antenatal care

BACKGROUND

Current measures of antenatal care use are limited to initiation of care and number of visits. This study aimed to describe the development and application of a tool to assess the adequacy of the content and timing of antenatal care.

METHODS

The Content and Timing of care in Pregnancy (CTP) tool was developed based on clinical relevance for ongoing antenatal care and recommendations in national and international guidelines. The tool reflects minimal care recommended in every pregnancy, regardless of parity or risk status. CTP measures timing of initiation of care, content of care (number of blood pressure readings, blood tests and ultrasound scans) and whether the interventions were received at an appropriate time. Antenatal care trajectories for 333 pregnant women were then described using a standard tool (the APNCU index), that measures the quantity of care only, and the new CTP tool. Both tools categorise care into 4 categories, from 'Inadequate' (both tools) to 'Adequate plus' (APNCU) or 'Appropriate' (CTP). Participants recorded the timing and content of their antenatal care prospectively using diaries. Analysis included an examination of similarities and differences in categorisation of care episodes between the tools.

RESULTS

According to the CTP tool, the care trajectory of 10,2% of the women was classified as inadequate, 8,4% as intermediate, 36% as sufficient and 45,3% as appropriate. The assessment of quality of care differed significantly between the two tools. Seventeen care trajectories classified as 'Adequate' or 'Adequate plus' by the APNCU were deemed 'Inadequate' by the CTP. This suggests that, despite a high number of visits, these women did not receive the minimal recommended content and timing of care.

CONCLUSIONS

The CTP tool provides a more detailed assessment of the adequacy of antenatal care than the current standard index. However, guidelines for the content of antenatal care vary, and the tool does not at the moment grade over-use of interventions as 'Inappropriate'. Further work needs to be done to refine the content items prior to larger scale testing of the impact of the new measure.

Adolescent pregnancy and gestational weight gain: do the Institute of Medicine recommendations apply?

OBJECTIVE

The purpose of this study was to examine the Institute of Medicine (IOM) guidelines for gestational weight gain in adolescents.

STUDY DESIGN

We studied a retrospective cohort using the Missouri Birth Certificate Registry and included subjects who were primiparous, who had singleton gestations, who were <20 years old, and who delivered at 24-44 weeks gestation. The exposure was defined as weight gain less than, within, or greater than IOM recommendations. Outcomes that were examined were small-for-gestational-age (SGA) infants, large-for-gestational age (LGA) infants, preterm delivery, infant death, preeclampsia, cesarean delivery, and operative vaginal delivery. The analysis was stratified by body mass index category.

RESULTS

In any body mass index category, inadequate weight gain was associated with increased odds of SGA infants, preterm delivery, and infant death. When subjects gained more than the IOM recommendations, the number of SGA infants decreased, with slight increases in the number of LGA infants, preeclampsia, and cesarean delivery.

CONCLUSION

Adolescents should be counseled regarding adequate weight gain in pregnancy. Further research is necessary to determine whether the IOM recommendations recommend enough weight gain in adolescents to optimize pregnancy outcomes.
