Physical Activity and Gestational Weight Gain in Hispanic Women

Objective: Hispanic women have high rates of excessive and inadequate gestational weight gain (GWG) according to Institute of Medicine (IOM) guidelines. Observational studies suggest that physical activity may be associated with GWG but have been conflicting and were largely conducted in non-Hispanic white populations. Design and Methods We prospectively evaluated the association between physical activity and compliance with GWG guidelines, total GWG, and rate of GWG among 1,276 Hispanic participants in Proyecto Buena Salud, a cohort study in Western Massachusetts. The Pregnancy Physical Activity Questionnaire was used to assess pre, early, mid, and late pregnancy physical activity according to both intensity (i.e., sedentary, moderate, and vigorous) and type (i.e., housework/caregiving, occupational, and sports/exercise). Results: A total of 26.9% of women gained within IOM guidelines, 21.2% had inadequate GWG, and 51.9% experienced excessive GWG. Overall, we did not observe statistically significant associations between type or intensity of physical activity during pre, early, mid, and late pregnancy and inadequate or excessive GWG, total GWG, or rate of GWG. Conclusions: In this prospective cohort study of Hispanic women, after controlling for important risk factors, pregnancy physical activity did not appear to be associated with GWG

Prenatal Depression and Risk of Short Interpregnancy Interval in a Predominantly Puerto Rican Population

Background: Short interpregnancy interval (IPI) is associated with risk of adverse pregnancy outcomes; however, few studies have evaluated the role of depression as a risk factor for short IPI. Puerto Rican women in the United States experience disparities in adverse birth outcomes and have the highest birth rates. Methods: We analyzed the association between prenatal depressive symptoms and IPI in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women in Western Massachusetts (2006–2011). Depression was measured using the Edinburgh Postnatal Depression Scale (EPDS) in early, mid, and late pregnancy. We calculated follow-up time as the difference between the date of delivery of the index pregnancy and the last menstrual period of the subsequent pregnancy using medical records and billing data. We defined short IPI as ≤18 months. Results: Of 1262 eligible women, 35% (n = 440) had at least probable minor depression (EPDS scores ≥13) and 25% (n = 315) had probable major depression (EPDS scores ≥15). Participants were followed for a median of 3.7 years (interquartile range = 1.4–6.0 years) and 240 (20.6%) participants experienced a short IPI. After adjusting for risk factors, women with probable minor depression (adjusted odds ratio [aOR] = 1.39, 95% confidence interval [CI] = 1.02–1.88) and probable major depression (aOR = 1.42, 95% CI = 1.02–1.97) during pregnancy had increased odds of short IPI. Conclusions: Prenatal depressive symptoms were common in this Puerto Rican population and were associated with a modest increase in odds of short IPI. Further examination of the pathways through which mental health may affect IPI in vulnerable populations is warranted

Risk Factors for Prenatal Depressive Symptoms Among Hispanic Women

Prior studies of risk factors for depressive symptoms during pregnancy are sparse and the majority have focused on non-Hispanic white women. Hispanics are the largest minority group in the US and have the highest birth rates

Correlates of High Perceived Stress Among Pregnant Hispanic Women in Western Massachusetts

Prenatal psychosocial stress has been associated with adverse pregnancy outcomes, even after controlling for known risk factors. This paper aims to evaluate correlates of high perceived stress among Hispanic women, a group with elevated rates of stress during pregnancy

Preliminary Findings from the Gulf War Women\u27s Cohort: Reproductive and Children\u27s Health Outcomes among Women Veterans

Reproductive outcomes, such as preterm birth, miscarriage/stillbirth, and pre-eclampsia, are understudied in veterans, particularly among Gulf War veterans (GWVs). During deployment, women GWVs were exposed to toxicant and nontoxicant exposures that may be associated with adverse reproductive and developmental outcomes. The data come from a survey of 239 participants from northeastern and southern U.S. cohorts of women veterans. The questionnaire collected information about the service history, current and past general health, reproductive and family health, demographic information, and deployment exposures. Odds ratios were computed with 95% confidence intervals between exposures in theater and reproductive/children\u27s health outcomes. GWVs experienced adverse reproductive outcomes: 25% had difficulty conceiving, and 31% had a pregnancy that ended in a miscarriage or stillbirth. Pregnancy complications were common among GWVs: 23% had a high-risk pregnancy, and 16% were diagnosed with pre-eclampsia. About a third of GWVs reported their children (38%) had a developmental disorder. Use of pesticide cream during deployment was associated with higher odds of all reproductive and developmental outcomes. The results demonstrate that GWVs experienced reproductive and children\u27s health outcomes at potentially high rates, and exploratory analyses suggest pesticide exposure as associated with higher odds of adverse reproductive outcomes. Future longitudinal studies of women veterans should prioritize examining reproductive and children\u27s health outcomes

Prepregnancy body mass index, gestational weight gain, and elevated depressive symptoms in a Hispanic cohort.

Our objective was to assess the associations among prepregnancy Body Mass Index (BMI), gestational weight gain (GWG), and elevated depressive symptoms across pregnancy

Physical activity and depressive symptoms during pregnancy among Latina women: a prospective cohort study

Abstract Background Latina women are at increased risk for antenatal depressive disorders, which are common during pregnancy and are associated with elevated risk for poor maternal health and birth outcomes. Physical activity is a potential mechanism to reduce the likelihood of depressive symptoms. The purpose of the study was to assess whether total and domain-specific physical activity in early pregnancy reduced risk for elevated antenatal depressive symptoms in mid-late pregnancy in a population of Latina women at high-risk for depression. Methods Data from 820 Latina participants in the prospective cohort study Proyecto Buena Salud was examined using multivariable logistic regression. Total, moderate/vigorous, and domain-specific physical activity (household/caregiving, occupational, sports/exercise, transportation) were assessed using the Pregnancy Physical Activity Questionnaire. The Edinburgh Postnatal Depression Scale was used to assess depressive symptoms and identify women with elevated symptoms indicative of at least probable minor depression and probable major depression. Results A total of 25.9% of participants experienced at least probable minor depression and 19.1% probable major depression in mid-late pregnancy. After adjusting for important risk factors, no significant associations were observed between total physical activity (4th Quartile vs.1st Quartile OR = 1.02, 95% CI = 0.61, 1.71; p-trend = 0.62) or meeting exercise guidelines in pregnancy (OR = 0.96, 95% CI = 0.65, 1.41) and at least probable minor depression; similarly, associations were not observed between these measures and probable major depression. There was a suggestion of increased risk of probable major depression with high levels of household/caregiving activity (4th Quartile vs 1st Quartile OR = 1.51, 95% CI = 0.93, 2.46), but this was attenuated and remained not statistically significant after adjustment. When we repeated the analysis among women who did not have elevated depressive symptoms in early pregnancy (n = 596), findings were unchanged, though a nonsignificant protective effect was observed for sport/exercise activity and probable major depression in fully adjusted analysis (OR = 0.63, 95% CI = 0.30, 1.33). Conclusion Among Latina women at high-risk for antenatal depression, early pregnancy physical activity was not associated with elevated depressive symptoms in mid-to-late pregnancy

Estudio Parto: postpartum diabetes prevention program for hispanic women with abnormal glucose tolerance in pregnancy: a randomised controlled trial – study protocol

Background: Diabetes and obesity have reached epidemic proportions in the U.S. with rates consistently higher among Hispanics as compared to non-Hispanic whites. Among Hispanic women diagnosed with gestational diabetes mellitus (GDM), 50% will go on to develop type 2 diabetes within 5 years of the index pregnancy. Although randomised controlled trials among adults with impaired glucose tolerance have shown that diet and physical activity reduce the risk of type 2 diabetes, such programs have not been tested in high-risk postpartum women. The overall goal of this randomised controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce risk factors for type 2 diabetes and cardiovascular disease among postpartum Hispanic women with a history of abnormal glucose tolerance during pregnancy. Methods/Design Hispanic pregnant women who screen positive for GDM will be recruited and randomly assigned to a Lifestyle Intervention (n = 150) or a Health & Wellness (control) Intervention (n = 150). Multimodal contacts (i.e., in-person, telephone, and mailed materials) will be used to deliver the intervention from late pregnancy (29 weeks gestation) to 12 months postpartum. Targets of the intervention are to achieve Institute of Medicine Guidelines for postpartum weight loss; American Congress of Obstetrician and Gynecologist guidelines for physical activity; and American Diabetes Association guidelines for diet. The intervention draws from Social Cognitive Theory and the Transtheoretical Model and addresses the specific cultural and environmental challenges faced by low-income Hispanic women. Assessments will be conducted at enrollment, and at 6-weeks, 6-months, and 12-months postpartum by trained bicultural and bilingual personnel blinded to the intervention arm. Efficacy will be assessed via postpartum weight loss and biomarkers of insulin resistance and cardiovascular risk. Changes in physical activity and diet will be measured via 7-day actigraph data and three unannounced 24-hour dietary recalls at each assessment time period. Discussion Hispanic women are the fastest growing minority group in the U.S. and have the highest rates of sedentary behavior and postpartum diabetes after a diagnosis of GDM. This randomised trial uses a high-reach, low-cost strategy that can readily be translated into clinical practice in underserved and minority populations. Trial registration NCT0167921

Strategies for recruiting Hispanic women into a prospective cohort study of modifiable risk factors for gestational diabetes mellitus

BACKGROUND: The purpose of this article was to describe effective strategies for recruitment of Hispanic women into a prospective cohort study of modifiable risk factors for gestational diabetes mellitus (GDM). Although Hispanic women have two to four times the risk of developing GDM compared with non-Hispanic white women, few GDM prevention studies have included Hispanic women. METHODS: The study was conducted in the ambulatory obstetrical practices of Baystate Medical Center located in a socioeconomically and ethnically diverse city in Massachusetts. The study employed a range of strategies to recruit Hispanic women based on a review of the literature as well as prior experience with the study population. RESULTS: Over a period of 32 months, a total of 851 Hispanic prenatal care patients were recruited. Among eligible women, 52.4% agreed to participate. Participants were young (70% <25 years), with low levels of education, and on public health insurance (81.5%); 88% were unmarried. Study design features such as use of bilingual recruiters, a flexible recruitment process, training recruiters to be culturally sensitive, use of culturally tailored materials, prescreening participants, participant compensation, seeking the cooperation of clinic staff, and continuous monitoring of recruitment goals emerged as important issues influencing recruitment. CONCLUSIONS: Findings suggest that investigators can successfully recruit pregnant women from ethnic minority groups of low socioeconomic status into observational studies. The study provides culturally appropriate recruitment strategies useful for practice-based settings recruiting Hispanic research participation

Clinical and Economic Evaluation of a Proteomic Biomarker Preterm Birth Risk Predictor: Cost-Effectiveness Modeling of Prenatal Interventions Applied to Predicted Higher-Risk Pregnancies Within a Large and Diverse Cohort

Objectives: Preterm birth occurs in more than 10% of U.S. births and is the leading cause of U.S. neonatal deaths, with estimated annual costs exceeding $25 billion USD. Using real-world data, we modeled the potential clinical and economic utility of a prematurity-reduction program comprising screening in a racially and ethnically diverse population with a validated proteomic biomarker risk predictor, followed by case management with or without pharmacological treatment. Methods: The ACCORDANT microsimulation model used individual patient data from a prespecified, randomly selected sub-cohort (N = 847) of a multicenter, observational study of U.S. subjects receiving standard obstetric care with masked risk predictor assessment (TREETOP; NCT02787213). All subjects were included in three arms across 500 simulated trials: standard of care (SoC, control); risk predictor/case management comprising increased outreach, education and specialist care (RP-CM, active); and multimodal management (risk predictor/case management with pharmacological treatment) (RP-MM, active). In the active arms, only subjects stratified as higher risk by the predictor were modeled as receiving the intervention, whereas lower-risk subjects received standard care. Higher-risk subjects\u27 gestational ages at birth were shifted based on published efficacies, and dependent outcomes, calibrated using national datasets, were changed accordingly. Subjects otherwise retained their original TREETOP outcomes. Arms were compared using survival analysis for neonatal and maternal hospital length of stay, bootstrap intervals for neonatal cost, and Fisher\u27s exact test for neonatal morbidity/mortality (significance, p \u3c .05). Results: The model predicted improvements for all outcomes. RP-CM decreased neonatal and maternal hospital stay by 19% (p = .029) and 8.5% (p = .001), respectively; neonatal costs\u27 point estimate by 16% (p = .098); and moderate-to-severe neonatal morbidity/mortality by 29% (p = .025). RP-MM strengthened observed reductions and significance. Point estimates of benefit did not differ by race/ethnicity. Conclusions: Modeled evaluation of a biomarker-based test-and-treat strategy in a diverse population predicts clinically and economically meaningful improvements in neonatal and maternal outcomes
