Objective: Prior studies indicate that inadequate and excessive gestational weight gain (GWG) are associated with poor maternal and infant outcomes, and that stress and anxiety may contribute to GWG. However, these studies often failed to use validated measures of stress and anxiety, measured only total GWG, and were limited to largely non-Hispanic White populations. We explored the association between stress and anxiety and GWG., Methods: We used data from 1,308 participants in Proyecto Buena Salud, a prospective cohort of predominantly Puerto Rican women 18-40 years of age (2006-2012). We measured stress with the Perceived Stress Scale and anxiety with the State-Trait Anxiety Scale, and abstracted GWG from medical records., Results: The average GWG was 31.0 ± 16.1 pounds. More than one-half of participants (51.8%) exceeded Institute of Medicine guidelines for GWG. After adjusting for age and pre-pregnancy body mass index, women in the highest quartiles of stress and anxiety in early pregnancy had approximately 4 lbs lower GWG (β = -3.89; SE = 1.54; p = .012 and β = -4.37; SE = 1.54; p = .005, respectively) as compared with those in the lowest quartiles. Similarly, women in the highest quartiles of mid/late pregnancy stress and anxiety had lower GWG (β = -3.84 lbs; SE = 1.39; p = .006, and β = -3.51 lbs; SE = 1.38; p = .011, respectively) and a lower rate of GWG in the second and third trimesters (β = -0.117 lbs/week; SE = 0.044; p = .008 and β = -0.116 lbs/week; SE = 0.043; p = .007, respectively), compared with those in the lowest quartiles., Conclusions: High stress and anxiety were associated with lower GWG. Interventions to decrease stress and anxiety during pregnancy should include counseling on maintaining healthy GWG., (Copyright © 2020 Jacobs Institute of Women's Health. Published by Elsevier Inc.

Objective/Background : Poor sleep during pregnancy is common and is associated with pregnancy complications. Physical activity (PA) is associated with better sleep in nonpregnant populations. However, studies among pregnant women are sparse, conflicting, and none have been conducted among Hispanic women, who face a disproportionate burden of poor sleep and pregnancy complications. Therefore, our objective was to examine the relationship between intensity- and domain-specific PA, respectively, on sleep quality and duration among Hispanic pregnant women. Participants : We evaluated these associations among participants ( n  = 251) in Estudio PARTO, an ongoing randomized controlled trial aimed at reducing type 2 diabetes among women at high risk. Methods : We assessed the cross-sectional relationship between PA (via Pregnancy PA Questionnaire) and sleep quality and duration (via Pittsburgh Sleep Quality Index) using baseline data (26.5 ± 6.9 weeks gestation). Results : In multivariable logistic models, household and caregiving activities were associated with higher odds of very poor sleep quality (OR = 2.69; 95% CI = 1.04 to 7.04) and with short (vs. medium) sleep duration (OR = 2.85; 95% CI = 1.07 to 7.56). In contrast, occupational PA was associated with lower odds of very poor sleep quality (OR = 0.39; 95% CI = 0.17 to 0.89). Light-intensity PA was associated with lower odds of long (vs. medium) sleep duration (OR = 0.13; 95% CI = 0.03 to 0.52). There were no statistically significant relationships between PA in any other domain and sleep. Conclusions : Prospective studies will be critical in evaluating the potential adverse impact of household and caregiving activities on poor sleep quality.

Purpose: To examine the effect of a prenatal exercise intervention on gestational weight gain (GWG) and to update meta-analyses., Design: Randomized controlled trial and meta-analysis., Setting: Obstetrical practices in a Western Massachusetts hospital., Patients: We analyzed 241 ethnically diverse pregnant participants at high risk for gestational diabetes in the Behaviors Affecting Baby and You (B.A.B.Y.) study. A total of 118 participants were randomized to an exercise intervention group and 123 to a comparison health and wellness intervention group., Intervention: A 12-week individually tailored, motivationally matched program designed to increase the compliance with guidelines for exercise during pregnancy (30 min/day)., Measures: The GWG and compliance with 2009 Institute of Medicine (IOM) guidelines for GWG abstracted from medical records., Analysis: Unadjusted logistic regression, intent-to-treat. Results were added to the existing meta-analyses using a random effects model., Results: Women randomized to the exercise group had a lower mean GWG than the comparison group (-0.97 kg, P value = .39) and were less likely to exceed IOM guidelines (odds ratio = 0.69, 95% confidence interval [CI] 0.34-1.40), but results were not statistically significant. Meta-analyses yielded a -0.63 kg (95% CI -1.17 to -0.08, P = .02) reduction in GWG and a 20% reduction in odds of exceeding IOM guidelines (95% CI 0.73 to 0.89) for the exercise intervention., Conclusion: Findings from this randomized trial among ethnically diverse women contribute to the results of meta-analyses supporting exercise as a means of attenuating GWG.

Objectives To examine associations between depression and preterm birth and small-for gestational age (SGA) among women of predominantly Puerto Rican descent, a population who experiences disparities in adverse birth outcomes and one of the highest infant mortality rates in the United States. Methods Proyecto Buena Salud (PBS) was a prospective cohort study conducted from 2006 to 2011 at a large tertiary care center in Western Massachusetts. Caribbean Islander (i.e., Puerto Rican and Dominican Republic) women were interviewed in early, mid and late pregnancy. Among 1262 participants, associations between depression, assessed using the Edinburgh Postnatal Depression Scale, and risk of preterm birth and small-for-gestational age (SGA) were evaluated. Results Women with at least probable minor depression [odds ratio (OR) = 1.77 (95% confidence interval (CI) = 1.02, 3.07)] or probable major depression [OR = 1.82 (95% CI = 1.01, 3.25)] in mid-pregnancy had an increased risk of SGA compared to non-depressed women in adjusted analyses. Borderline significant associations were observed between increasing levels of depressive symptom scores in early and mid-pregnancy [OR = 1.05 (95% CI = 1.00, 1.11) and OR = 1.04 (95% CI = 1.00, 1.09), respectively] and each additional trimester of exposure to probable major depression across mid- to late pregnancy [OR = 1.66 (95% CI = 1.00, 2.74)] and SGA. Late pregnancy depression was not associated with SGA; depression during pregnancy was not associated with preterm birth. Conclusions for Practice In this population of predominantly Puerto Rican women, mid-pregnancy depression increased risk for SGA. Findings can inform culturally appropriate, targeted interventions to identify and treat pregnant women with depression.

Introduction Latinas in the United States on average have poorer birth outcomes than Whites, yet considerable heterogeneity exists within Latinas. Puerto Ricans have some of the highest rates of adverse outcomes and are understudied. The goal of this study was to determine if acculturation was associated with adverse birth outcomes in a predominantly Puerto Rican population. Methods We conducted a secondary analysis of Proyecto Buena Salud, a prospective cohort study conducted from 2006 to 2011. A convenience sample of pregnant Latina women were recruited from a tertiary care hospital in Massachusetts. Acculturation was measured in early pregnancy; directly via the Psychological Acculturation Scale, and via proxies of language preference and generation in the United States. Birth outcomes (gestational age and birthweight) were abstracted from medical records (n = 1362). Results After adjustment, psychological acculturation, language preference, and generation was not associated with odds of preterm birth. However, every unit increase in psychological acculturation score was associated with an increase in gestational age of 0.22 weeks (SE = 0.1, p = 0.04) among all births. Women who preferred to speak Spanish (β = -0.39, SE = 0.2, p = 0.02) and who were first generation in the US (β = -0.33, SE = 0.1, p = 0.02) had significantly lower gestational ages than women who preferred English or who were later generation, respectively. Similarly, women who were first generation had babies who weighed 76.11 g less (SE = 35.2, p = 0.03) than women who were later generation. Discussion We observed a small, but statistically significant adverse impact of low acculturation on gestational age and birthweight in this predominantly Puerto Rican population.

Objectives To estimate the associations of moderate and vigorous intensity exercise during pregnancy with the rate of gestational weight gain (GWG) from gestational diabetes (GDM) diagnosis to delivery, overall and stratified by prepregnancy overweight/obesity. Methods Prospective cohort study with physical activity reported shortly after the GDM diagnosis and prepregnancy weight and post-diagnosis GWG obtained from electronic health records (n = 1055). Multinomial logistic regression models in the full cohort and stratified by prepregnancy overweight/obesity estimated associations of moderate and vigorous intensity exercise with GWG below and above the Institute of Medicine's (IOM) prepregnancy BMI-specific recommended ranges for weekly rate of GWG in the second and third trimesters. Results In the full cohort, any participation in vigorous intensity exercise was associated with decreased odds of GWG above recommended ranges as compared to no participation [odds ratio (95 % confidence interval): 0.63 (0.40, 0.99)], with a significant trend for decreasing odds of excess GWG with increasing level of vigorous intensity exercise. Upon stratification by prepregnancy overweight/obesity, significant associations were only observed for BMI ≥ 25.0 kg/m(2): any vigorous intensity exercise, as compared to none, was associated with 54 % decreased odds of excess GWG [0.46 (0.27, 0.79)] and significant trends were detected for decreasing odds of GWG both below and above the IOM's recommended ranges with increasing level of vigorous exercise (both P ≤ 0.03). No associations were observed for moderate intensity exercise. Conclusions for Practice In women with GDM, particularly overweight and obese women, vigorous intensity exercise during pregnancy may reduce the odds of excess GWG., Competing Interests: The authors have no relevant conflict of interest to disclose.

Background: The proportion of women entering pregnancy overweight or obese has been rising and, in turn, is associated with adverse maternal and fetal outcomes. Gestational weight gain (GWG) exceeding Institute of Medicine (IOM) guidelines further increases health risks and has been independently associated with postpartum weight retention. Hispanic women are disproportionately affected by overweight and obesity, but have had limited access to interventions that promote healthy lifestyles due to cultural, socioeconomic, and language barriers. Therefore, the overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce excess GWG, increase postpartum weight loss, and improve maternal metabolic status among overweight/obese Hispanic women., Methods/design: Overweight/obese Hispanic women are recruited in early pregnancy and randomly assigned to a Lifestyle Intervention (n = 150) or a Comparison Health and Wellness (control) intervention (n = 150). Multimodal contacts (i.e., in-person, telephone counseling, and mailed print-based materials) are used to deliver the intervention from early pregnancy (12 weeks gestation) to 6 months postpartum, with follow-up to 1 year postpartum. Targets of the intervention are to achieve IOM Guidelines for GWG and 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 includes strategies to address the specific social, cultural, and economic challenges faced by low-income Hispanic women. Assessments are conducted at baseline (~10 weeks gestation), mid pregnancy (24-28 weeks gestation), late pregnancy (32-34 weeks gestation) and postpartum at 6-weeks, 6-months, and 12-months by bicultural and bilingual personnel blinded to the intervention arm. Efficacy is assessed via GWG, postpartum weight loss, and biomarkers of glycemic control, insulin resistance, and cardiovascular disease risk factors. Changes in physical activity and diet are measured via 7-day accelerometer data and 24-h dietary recalls at each assessment time period., Discussion: Hispanic women are the fastest growing minority group in the U.S. and are disproportionately affected by overweight and obesity. 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: NCT01868230 May 29, 2013.

Objectives: Our objective was to assess the associations among prepregnancy Body Mass Index (BMI), gestational weight gain (GWG), and elevated depressive symptoms across pregnancy., Methods: We evaluated these associations among 1,090 participants in Proyecto Buena Salud, a prospective cohort study of Hispanic (predominantly Puerto Rican) women in Western Massachusetts. BMI and GWG were self-reported; GWG was classified according to the 2009 Institute of Medicine guidelines. Depressive symptoms were assessed in early, mid-, and late pregnancy using the 10-item Edinburgh Postnatal Depression Scale (EPDS). We defined elevated depressive symptoms as EPDS scores ≥13 and ≥15., Results: In multivariable, longitudinal modeling, overweight (25.0 to <30 kg/m2) women had an odds ratio of 0.53 (95% CI [0.31, 0.90]) for EPDS scores ≥13 and 0.51 (95% CI [0.28, 0.91]) for EPDS scores ≥15 compared to normal weight women. We did not observe an association between GWG or an interaction between BMI and GWG, in predicting elevated depressive symptoms., Conclusions: Our findings provide preliminary support for an association of prepregnancy overweight status and lower depressive symptoms across pregnancy in Hispanic women. Future research should focus on potential social and cultural differences in perceptions of weight and weight gain in the perinatal period and how these influence psychological health., (PsycINFO Database Record (c) 2015 APA, all rights reserved.)

Objective: We reviewed studies of maternal depression and preterm birth (PTB), low birthweight (LBW) and small-for-gestational-age (SGA) in the context of methodological differences between studies and potential limitations., Methods: We conducted a literature search of PubMed (1996-2011) for English-language studies of maternal depression and (1) PTB and gestational age (GA), (2) LBW and birthweight (BW) and (3) SGA. Thirty-six studies met eligibility criteria., Results: Elevated depression levels, particularly in early- to mid-pregnancy, appear to increase risk of PTB and SGA. Findings suggest an increased risk for LBW, but were less consistent. Methodological differences and limitations likely contributed to conflicting findings. A wide range of depression measures were used with the majority of studies utilizing measures not designed, or validated, for pregnant women. Studies failed to assess depression at multiple pregnancy time points, thus constraining the ability to assess the impact of duration and pattern of exposure to depression. Antidepressant use and co-morbid psychosocial factors were rarely considered as potential confounders or effect modifiers., Conclusions: Studies suggest that depression during pregnancy may be an important risk factor for PTB and SGA, and possibly LBW. Improved study methodology is needed to elucidate the consequence of maternal depression on adverse birth outcomes.

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., Methods: 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 was prospectively evaluated. 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., (Copyright © 2013 The Obesity Society.)

Purpose: In this review, we provide researchers and practitioners with an overview of the physical activity and pregnancy literature to promote prenatal physical activity, improve measurement, further elucidate the role of activity in reducing maternal health complications, and inform future research., Method: We examined past and present physical activity and pregnancy studies and highlight key papers with a focus on maternal health outcomes to best inform physical activity promotion efforts., Results: We discuss: (a) historical overview of prenatal physical activity relative to the physical activity guidelines, how they have changed over time, and how evidence of the effect of prenatal activity on maternal/fetal health outcomes has affected clinical recommendations; (b) existing tools and challenges associated with measuring prenatal physical activity; (c) empirical evidence on multilevel determinants of prenatal activity to guide future intervention work; (d) empirical evidence of prenatal activity on adverse maternal outcomes (gestational diabetes mellitus, preeclampsia, excessive gestational weight gain) from observational and intervention studies; and (e) summary/recommendations for future research and practice., Conclusions: The physical activity and pregnancy literature has evolved over the past 50 years, and there is sufficient empirical evidence to support the promotion of moderate-to-vigorous prenatal physical activity for maternal health benefits. Future studies and interventions should be carefully designed, theoretically driven, and include validated and reliable activity measures. Researchers and practitioners should also consider the multifaceted determinants and outcomes of prenatal physical activity and intervene to promote physical activity before, during, and after pregnancy.

Background: Identifying risk factors that affect excess weight gain during pregnancy is critical, especially among women who are at a higher risk for obesity. The goal of this study was to determine if acculturation, a possible risk factor, was associated with gestational weight gain in a predominantly Puerto Rican population., Methods: We utilized data from Proyecto Buena Salud, a prospective cohort study of Hispanic women in Western Massachusetts, United States. Height, weight and gestational age were abstracted from medical records among participants with full-term pregnancies (n=952). Gestational weight gain was calculated as the difference between delivery and prepregnancy weight. Acculturation (measured via a psychological acculturation scale, generation in the US, place of birth and spoken language preference) was assessed in early pregnancy., Results: Adjusting for age, parity, perceived stress, gestational age, and prepregnancy weight, women who had at least one parent born in Puerto Rico/Dominican Republic (PR/DR) and both grandparents born in PR/DR had a significantly higher mean total gestational weight gain (0.9 kg for at least one parent born in PR/DR and 2.2 kg for grandparents born in PR/DR) and rate of weight gain (0.03 kg/wk for at least one parent born in PR/DR and 0.06 kg/wk for grandparents born in PR/DR) vs. women who were of PR/DR born. Similarly, women born in the US had significantly higher mean total gestational weight gain (1.0 kg) and rate of weight gain (0.03 kg/wk) vs. women who were PR/ DR born. Spoken language preference and psychological acculturation were not significantly associated with total or rate of pregnancy weight gain., Conclusion: We found that psychological acculturation was not associated with gestational weight gain while place of birth and higher generation in the US were significantly associated with higher gestational weight gain. We interpret these findings to suggest the potential importance of the US "obesogenic" environment in influencing unhealthy pregnancy weight gains over specific aspects of psychological acculturation.

Background: A growing body of evidence suggests that physical activity during pregnancy can reduce risk of pregnancy complications. However, factors influencing activity in pregnant Hispanic women, who have high rates of sedentary activity as compared to non-Hispanic whites, are not well characterized., Purpose: To assess patterns and correlates of physical activity among 1355 participants in Proyecto Buena Salud, a prospective cohort of pregnant Hispanic women in Massachusetts from 2006 to 2011., Methods: Analyses were conducted in 2012. Pre-, early-, mid-, and late-pregnancy physical activity were assessed using the Pregnancy Physical Activity Questionnaire. Women reported the frequency and duration of household/caregiving, occupational, sports/exercise, and transportation activities and were classified according to compliance with American College of Obstetricians and Gynecologists guidelines for physical activity., Results: Household/caregiving activity was the primary mode of pregnancy activity ranging from 56% to 60% of total activity while sports/exercise contributed the least (<10%). Compared to nulliparous women, women with two or more children were 85% less likely to become inactive at any time during pregnancy (OR=0.15, 95% CI=0.04, 0.56, p-trend <0.01). Women with one or more children increased their total physical activity on average 9.73±2.04 MET-hours/week and 12.04±2.39 MET-hours/week, respectively, with the onset of pregnancy (p<0.01). Those with the highest levels of total physical activity prior to pregnancy were 87% less likely to become inactive with the onset of pregnancy than those who were inactive prior to pregnancy (OR=0.13, 95% CI= 0.05, 0.29)., Conclusions: Findings can inform culturally appropriate interventions designed to reduce pregnancy complications through the promotion of physical activity during pregnancy., (Copyright © 2012 American Journal of Preventive Medicine.

Background: The ability to measure and track changes in risk-adjusted obstetric complication rates using administrative data underpins efforts to improve obstetric quality of care, but the validity of this approach has not been adequately evaluated. We sought to assess the validity of using composites of ICD-9-CM codes to identify selected categories obstetric complications and risk factors associated with complications., Methods: Patients with ICD-9-CM codes for obstetric trauma/laceration, infection, haemorrhage, episiotomy or obesity discharged between January 2009 and March 2010 were identified in the study hospital's administrative data. One hundred medical records with ICD-9-CM codes of interest were randomly selected for review from each of the five categories. An additional 60 medical records without the ICD-9-CM codes of interest served as controls for each category. Sensitivity and specificity for the selected categories was estimated using inverse proportional weighting to adjust for sampling based on presence of one of the ICD-9-CM codes of interest., Results: Weighted sensitivities ranged from 0.15 [95% CI 0.11, 0.20] for obesity to 1.00 for overall infection while specificities ranged from 0.994 [95% CI 0.987, 0.998] for obesity to 0.999 [95% CI 0.996, 1.000] for episiotomy. Obese patients were not reliably identified and it was not possible ascertain whether some diagnoses were present on admission., Conclusions: For selected categories of obstetric complication diagnoses, use of composite sets of ICD-9-CM codes may be a valid method to identify patients within these complication categories., (© 2012 Blackwell Publishing Ltd.)

Pregnancy has been proposed as a critical period for the development of subsequent maternal overweight and/or obesity. Excessive gestational weight gain is, in turn, associated with maternal complications such as cesarean delivery, hypertension, preeclampsia, impaired glucose tolerance, and gestational diabetes mellitus. Although there is substantial evidence that targeting at-risk groups for type 2 diabetes prevention is effective if lifestyle changes are made, relatively little attention has been paid to the prevention of excessive gestational weight gain and impaired glucose tolerance during pregnancy. Latinos are the largest minority group in the United States, with the highest birth and immigration rates of any minority group and are disproportionately affected by overweight and obesity. However, due to cultural factors, socioeconomic factors, and language barriers, Latinos have had limited access to public health interventions that promote healthy lifestyles. Therefore, the objective of this article is to review the scientific evidence regarding the association between physical activity, dietary behaviors, and gestational weight gain and impaired glucose tolerance among Latinas. A second objective is to discuss how lifestyle interventions including weight management through diet and exercise could be successful in reducing the risk of excessive gestational weight gain and gestational diabetes mellitus. Finally, recommendations are provided for future lifestyle intervention programs in this population with a focus on translation and dissemination of research findings.

Background: Studies on the relationship between prenatal psychosocial risk factors and breastfeeding are sparse, particularly in Hispanic women., Methods: We evaluated this association among 424 participants in Proyecto Buena Salud, an ongoing prospective cohort of pregnant Hispanic women in Western Massachusetts. The Perceived Stress Scale (PSS), the State-Trait Anxiety Inventory (STAI), and the Edinburgh Postnatal Depression Scale (EPDS) were administered by bilingual interviewers in early pregnancy (mean 13.6 weeks gestation) and midpregnancy (mean 25.7 weeks gestation). Information on sociodemographic, behavioral, and acculturation factors was also collected. Breastfeeding intention was abstracted from medical records. Poisson regression was used to calculate prevalence risk ratios (PRR) and 95% confidence intervals (CI)., Results: A total of 274 (64.6%) women reported a positive intention to breastfeed. In multivariate analyses, women in the highest quartile of perceived stress (PRR 0.76, 95% CI 0.62-0.94) in early pregnancy and highest quartile of anxiety in early pregnancy (PRR 0.66, 95% CI 0.54-0.81) and midpregnancy (PRR 0.80, 95% CI 0.64-1.00) were less likely to intend to breastfeed compared to women in the lowest quartile. Women who had at least probable minor depression (EPDS score ≥13) (PRR 0.79, 95% CI 0.65-0.95) or probable major depression (EPDS score ≥15) (PRR 0.77, 95% CI 0.62-0.96) during midpregnancy were less likely to intend to breastfeed compared to women without depressive symptoms. Similarly, women with persistent depressive symptoms over pregnancy were 24%-33% less likely to intend to breastfeed compared to women without depressive symptoms., Conclusions: Psychosocial risk factors during pregnancy are important predictors of breastfeeding intention among Hispanic women.

Purpose: Prior studies of the association between physical activity and risk of hypertensive disorders of pregnancy have been conflicting, failed to assess total physical activity, and included few Hispanic women, the largest minority group in the United States with the highest birth rates., Methods: We examined this association among 1043 participants in the Latina Gestational Diabetes Mellitus Study, a prospective cohort of predominantly Puerto Rican prenatal care patients conducted from 2000 to 2004 in western Massachusetts. Physical activity before and in early pregnancy was assessed by bilingual interviewers using a modified version of the Kaiser Physical Activity Survey., Results: Fifty women (4.8%) were diagnosed with hypertensive disorders of pregnancy and 30 (2.9%) with preeclampsia. In multivariable analyses, there was a statistically significant trend of decreasing risk of hypertensive disorders with increasing sports/exercise in early pregnancy (P(trend) = 0.04). High levels of early pregnancy active living activity (odds ratio (OR) = 0.4, 95% confidence interval (CI) = 0.1-1.1, P(trend) = 0.07) and household/care giving activity (OR = 0.4, 95% CI = 0.1-1.3, P(trend) = 0.07) were associated with a 60% reduction in risk of hypertensive disorders relative to low levels; however, these associations were of marginal statistical significance. High levels of total physical activity (OR = 0.3, 95% CI = 0.1-1.0, P(trend) = 0.06) in early pregnancy were associated with a 70% reduction in the risk of hypertensive disorders relative to low levels; however, this association was also of marginal statistical significance. Prepregnancy physical activity was not associated with hypertensive disorders., Conclusions: These results in a Hispanic population, although based on small numbers of cases, corroborate previous studies suggesting that recreational activity in early pregnancy reduces the risk of hypertensive disorders of pregnancy.

To estimate the association between multiple domains of physical activity and risk of small-for-gestational-age (SGA) birth. We utilized data from 1,040 participants in the Latina Gestational Diabetes Mellitus Study, a prospective cohort of predominantly Puerto Rican prenatal care patients in Massachusetts. Physical activity was assessed by bilingual interviewers using a modified version of the Kaiser physical activity survey in early (mean = 15 weeks) and mid pregnancy (mean = 28 weeks). Physical activity (i.e., sports/exercise, household, occupational, and active living) in pre, early and mid pregnancy was categorized in quartiles. SGA was classified as <10th percentile of birth weight for gestational age. Pre- and early-pregnancy physical activity were not associated with SGA. In multivariable analyses, women with high total activity in mid-pregnancy had a decreased risk of SGA [risk ratio (RR) = 0.42; 95% confidence interval (CI) 0.21-0.82; p(trend) = 0.003] as compared to those with low total activity. Findings were similar for high household activity (RR = 0.69; 95% CI = 0.34-1.40; p(trend) = 0.26), active living (RR = 0.63; 95% CI = 0.35-1.13; p(trend) = 0.04), and occupational activity (RR = 0.79, 95% CI = 0.47-1.34; p(trend) = 0.26). High levels of sports/exercise were associated with an increased SGA risk without a significant dose-response association (RR = 2.14, 95% CI 1.04-4.39; p(trend) = 0.33). Results extend prior studies of physical activity and SGA to the Hispanic population.

Factors influencing gestational weight gain are incompletely understood, particularly among Hispanic women. We assessed medical, sociodemographic, behavioral, and psychosocial predictors of overall gestational weight gain, as well as gains below, within, or above the range recommended by the Institute of Medicine (IOM) within a prospective study of 770 Hispanic (predominantly Puerto Rican) prenatal care patients at a large tertiary care facility in Western Massachusetts. One third of women gained within the recommended range, 22% gained below, and 45% gained above the range. In multivariate analysis, women in the highest category of BMI (P(trend)<0.001) and parity (P(trend)<0.001) gained on average 9 lbs less than those in the lowest category. Increasing time in residence in the continental United States (P(trend)<0.01) as well as a number of prenatal care visits (P(trend)=0.03) were positively associated with weight gain. Overweight women (odds ratio (OR)=2.2, 95% confidence interval (CI) 1.3, 3.8) and those over age 30 years (OR=2.5, 95% CI 1.2, 5.0) were more likely to gain above the IOM range as compared to normal-weight women and those aged 20-24, respectively. Women with <10 years of residence in the United States were 50% less likely to gain above the IOM range as compared to third-generation women (95% CI 0.3, 0.9). Findings identify determinants of gestational weight gain which can form the basis of targeted interventions in this rapidly growing ethnic group.

Objective: Studies in predominantly non-Hispanic white populations have suggested that physical activity during pregnancy is associated with a reduced risk of gestational diabetes mellitus (GDM). There are few such studies in Hispanic women, a group at increased risk for GDM., Methods: We conducted a prospective cohort study of household/caregiving, occupational, sports/exercise, and active living habits and the risk of GDM among 1006 Hispanic (predominantly Puerto Rican) prenatal care patients in western Massachusetts from 2000 to 2004. Prepregnancy, early pregnancy, and midpregnancy physical activity was assessed using the Kaiser Physical Activity Survey., Results: A total of 33 women (3.3%) were diagnosed with GDM, and 119 women (11.8%) were diagnosed with abnormal glucose tolerance. There were no significant associations between GDM risk and occupational and active living activities in prepregnancy, early pregnancy, and midpregnancy or with a change in levels of household/caregiving, occupational, and active living activities from prepregnancy to during pregnancy. However, after controlling for age and prepregnancy body mass index (BMI), women in the highest quartile of prepregnancy (OR = 0.2, 95% CI 0.1-0.8, p(trend) = 0.03) and midpregnancy (OR = 0.2, 95% CI 0.1-0.8, p(trend) = 0.004) household/caregiving activities as well as midpregnancy sports/exercise (0.1, 95% CI 0.0-0.7, p(trend) = 0.12) had a reduced risk of GDM compared with women in the lowest quartile., Conclusions: Findings in this Hispanic population, although based on small numbers of cases, are consistent with prior research among predominantly non-Hispanic white populations.

Objectives: We explored whether higher levels of acculturation were associated with higher rates of cigarette smoking among pregnant Hispanic women residing in the United States., Methods: We evaluated data from the Latina Gestational Diabetes Mellitus Study, a prospective study of 1231 Hispanic prenatal care patients conducted from 2000 to 2004 in Massachusetts. Self-reported data on acculturation, cigarette smoking, and covariates were collected by bilingual interviewers using a questionnaire. We conducted logistic regression multivariate analyses to examine the impact of acculturation level on the odds of smoking., Results: Overall, 21% of women reported smoking during pregnancy. Acculturation was associated with elevated smoking rates in pregnant Hispanic women. US-born Hispanic women who preferred English had more than twice the odds of smoking compared with Puerto Rican or foreign-born Hispanic women who preferred Spanish (odds ratio [OR]=2.76, 95% confidence interval [CI] 1.36, 5.63)., Conclusions: Our findings suggest that higher-acculturated Hispanic women living in the United States are more likely to smoke cigarettes during pregnancy than are less-acculturated Hispanic women. These results will inform interventions aimed at reducing cigarette smoking during pregnancy among US Hispanic women.

Background: Participation in physical activity during pregnancy may reduce the risk of gestational diabetes mellitus and preeclampsia and help prevent excess maternal weight gain. However, studies describing patterns and correlates of activity during pregnancy are sparse. The purpose of this cross-sectional study was to describe total physical activity (household/caregiving, occupational, leisure, sports/exercise, and transportation) and correlates of total physical activity in a racially and economically diverse sample of 233 prenatal care patients., Methods: Bilingual interviewers administered three 24-hour physical activity recalls among women in the first trimester (11%), second trimester (36%), and third trimester (53%) of pregnancy., Results: Median total energy expenditure (MET-hours/day) was similar among women in the first and second trimesters (33.4 and 33.8 MET-hours/day, respectively) and was slightly, but not statistically significantly, lower among women in the third trimester (32.6 MET-hours/day). Moderate intensity activity followed a similar pattern, being statistically significantly lower among women in the third trimester; vigorous intensity activity was low among women in each trimester of pregnancy. In terms of activity type, household/ caregiving activity was the largest contributor to both total and combined moderate and vigorous intensity energy expenditure among women in each trimester, constituting 24%-40% of total energy expenditure. Overall, total energy expenditure was highest in white non-Hispanic women and positively associated with increasing education and a history of previous live births (p < 0.01)., Conclusions: Results from this study highlight the importance of including household/caregiving and occupational activities in addition to sports/exercise activities in the assessment of total energy expenditure during pregnancy.

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. [ABSTRACT FROM AUTHOR]

Vitamin D deficiency is common during pregnancy and higher in Hispanic as compared with non-Hispanic white women. However, the association between vitamin D deficiency and adverse pregnancy outcomes remains unclear and may vary across ethnic groups, in part because of genetic variation in the metabolism of vitamin D. Few studies have included Hispanic women. Therefore, we investigated this association among 237 participants in the Behaviors Affecting Baby and You Study, a randomised trial of an exercise intervention among ethnically diverse prenatal care patients in Massachusetts. Baseline serum 25-hydroxyvitamin D (25(OH)D) was measured at 15·2 (sd 4·7) weeks’ gestation. Information on adverse pregnancy outcomes was abstracted from medical records. Mean 25(OH)D was 30·4 (sd 12·0) ng/ml; 53·2 % of participants had insufficient (<30 ng/ml) and 20·7 % had deficient (<20 ng/ml) 25(OH)D levels. After adjusting for month of blood draw, gestational age at blood draw, gestational age at delivery, age, BMI and Hispanic ethnicity, women with insufficient and deficient vitamin D had infants with birth weights 139·74 (se 69·16) g (P=0·045) and 175·52 (se 89·45) g (P=0·051) lower compared with women with sufficient vitamin D levels (≥30 ng/ml). Each 1 ng/ml increase in 25(OH)D was associated with an increased risk for gestational diabetes mellitus among Hispanic women only (relative risk 1·07; 95 % CI 1·03, 1·11) in multivariable analysis. We did not observe statistically significant associations between maternal vitamin D status and other pregnancy outcomes. Our findings provide further support for an adverse impact of vitamin D deficiency on birth weight in Hispanic women. [ABSTRACT FROM AUTHOR]

Objective To examine the association of gestational weight gain and dietary factors with abnormal glucose tolerance (AGT). Methods We conducted a prospective cohort study among 813 Hispanic prenatal care patients in Massachusetts. Gestational weight gain and oral glucose tolerance test results were abstracted from medical records. Dietary intake was assessed using a semi-quantitative food frequency questionnaire. Target weight gain was based on BMI-specific weekly weight gain rates established by the Institute of Medicine (IOM). Results We observed a statistically significant interaction between prepregnancy BMI and weight gain in relation to AGT ( P < 0.01). Class II/III (BMI ≥ 35 kg/m2) obese women who had a high rate of weight gain (>0.30 kg/week) or who exceeded target weight were 3--4 times as likely to develop AGT compared to women who gained within IOM ranges (OR = 4.2, 95% CI 1.1--16.0, OR = 3.2 95% CI 1.0--10.5, respectively). Increasing levels of saturated fat and fiber and decreasing levels of energy-dense snack foods and polyunsaturated fat:saturated fat ratio were significantly associated with increased risk of AGT, independent of gestational weight gain. Conclusions Weight gain among class II/III obese women and certain dietary components may represent modifiable risk factors for AGT. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Women with a history of gestational diabetes mellitus (GDM) are at high risk for developing type 2 diabetes (diabetes mellitus, DM). The American Diabetes Association recommends regular postpartum diabetes screening for women with a history of GDM, but the American College of Obstetricians and Gynecologists (ACOG) is not as directive. We sought to examine postpartum glycemic testing in women diagnosed with GDM. METHODS: We conducted an observational cohort study of women diagnosed with GDM at one of two large academic medical centers between 2000 and 2001. Kaplan-Meier estimates of the time from delivery to the first postpartum DM screening tests were determined, and predictors of postpartum DM screening were examined using Cox proportional hazards testing. RESULTS: Only 37% of eligible women underwent the postpartum diabetes screening tests recommended by the American Diabetes Association (fasting glucose or oral glucose tolerance test [OGTT]), with a median time from delivery to the first such testing of 428 days. By comparison, 94% of women underwent postpartum cervical cancer screening using a Papanicolaou (Pap) test, with a median time from delivery to Pap testing of 49 days. Even when random glucose testing was included in a broad definition of postpartum DM screening (random or fasting glucose, glycosylated hemoglobin, or OGTT), only two thirds of women (67%) received a postpartum glycemic assessment. CONCLUSION: In the population studied, only 37% of women with a history of GDM were screened for postpartum DM according to guidelines published by the American Diabetes Association. Efforts to improve postpartum DM screening in this high-risk group are warranted. [ABSTRACT FROM AUTHOR]

The article discusses a systematic review of postpartum lifestyle interventions conducted by J. Guo et al to prevent type 2 diabetes among women with a history of gestational diabetes mellitus (GDM). Finding of the systematic review highlight the need for larger studies that should address barriers to fully capitalize on pregnancy as a stress test and the diagnosis of GDM as an opportunity to intervene.

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.

Objective: Prepregnancy body mass index (BMI) and gestational weight gain have been associated with hypertensive disorders of pregnancy, but previous studies have included few Latinas, a group at increased risk. Study Design: We examined these associations in the Latina Gestational Diabetes Mellitus Study, a prospective cohort of 1231 women conducted from 2000 to 2004. Results: In multivariable analysis, obese women (BMI > 29.0 kg/m2) had 2.5 times the risk of hypertensive pregnancy (95% confidence interval [CI], 1.3-4.8) and 2.7 times the risk of preeclampsia (95% CI, 1.2-5.8), compared with women whose BMI was 19.8 to 26.0 kg/m2. Women with excessive gestational weight gain had a 3-fold increased risk of a hypertensive disorder of pregnancy (95% CI, 1.1-7.2) and a 4-fold risk of preeclampsia (95% CI, 1.2-14.5), compared with women achieving weight gain guidelines. Conclusion: These findings suggest prepregnancy obesity and excessive weight gain are associated with hypertension in pregnancy in a Latina population and could be potentially modifiable risk factors.

OBJECTIVE: To examine the effect of an individually tailored, motivationally matched prenatal exercise intervention on gestational diabetes mellitus (GDM) and other measures of glucose intolerance among ethnically diverse prenatal care patients at increased risk for GDM. METHODS: The Behaviors Affecting Baby and You study randomized eligible women at a mean (standard deviation) of 18.2 (4.1) weeks of gestation to a 12-week individually tailored, motivationally matched exercise intervention or a comparison health and wellness intervention. The goal of the exercise intervention was to achieve the American College of Obstetricians and Gynecologists' guidelines for physical activity during pregnancy. Diagnosis of GDM, impaired glucose tolerance, abnormal glucose screen, and screening glucose values (mg/dL) were abstracted from medical records. A sample size of 352 women (176 per group) was planned to have 80% power to detect reductions in risk of 35% or larger. RESULTS: From July 2007 to December 2012, a total of 251 (86.5%) women completed the intervention; n=124 and 127 in the exercise and comparison interventions, respectively. Based on an intention-to-treat analysis, no statistically significant differences between the intervention groups were observed; the relative odds of GDM in the exercise group was 0.61 (95% confidence interval [CI] 0.28-1.32) as compared with the health and wellness comparison group. Odds ratios for impaired glucose tolerance and abnormal glucose screen were 0.68 (95% CI 0.35-1.34) and 0.86 (95% CI 0.51-1.47), respectively. The intervention had no effect on birth outcomes. CONCLUSION: In this randomized trial among ethnically diverse pregnant women at increased risk for GDM, we found that a prenatal exercise intervention implemented in the second trimester did not result in a statistically significant reduction in relative odds for GDM, impaired glucose tolerance, or abnormal glucose screen.

Abstract: Aims: Hispanic women are at increased risk of gestational diabetes mellitus (GDM) as compared to non-Hispanic white women. While smoking has been associated with increased risk of type 2 diabetes, studies of smoking and GDM are sparse and conflicting. Therefore, we evaluated the relationship between cigarette smoking and GDM in Hispanic women. Methods: We conducted a pooled analysis of two Hispanic datasets based in Massachusetts: the UMass Medical Health Care dataset and the Proyecto Buena Salud dataset. A total of 3029 Hispanic prenatal care patients with singleton gestations were included. Cigarette smoking prior to and during pregnancy was collected via self-report. Diagnosis of GDM was abstracted from medical records and confirmed by study obstetricians. Results: One-fifth of participants (20.4%) reported smoking prior to pregnancy, and 11.0% reported smoking in pregnancy. A total of 143 women (4.7%) were diagnosed with GDM. We did not observe an association between pre-pregnancy cigarette smoking and odds of GDM (multivariable OR=0.77, 95% CI 0.47, 1.25). In contrast, smoking during pregnancy was associated with a 54% reduction in odds of GDM (OR=0.46, 95% CI 0.22, 0.95). However, this association was no longer statistically significant after adjustment for age, parity, and study site (OR=0.47, 95% CI 0.23, 1.00). Conclusions: In this population of Hispanic pregnant women, we did not observe statistically significant associations between pre-pregnancy smoking and odds of GDM. A reduction in odds of GDM among those who smoked during pregnancy was no longer apparent after adjustment for important diabetes risk factors. [Copyright &y& Elsevier]
