War-Affected South Sudanese in Settings of Preflight, Flight, and Resettlement: a Systematic Review and Meta-analysis of Trauma-Associated Mental Disorders.

Background: South Sudanese have experienced prolonged exposure to conflict and displacement regionally and globally, with studies in different settings yielding vastly inconsistent rates of trauma-associated mental disorders. This systematic review and meta-analysis aimed to synthesize the methodological approach and quality, trauma exposure, risk and protective factors, and aggregate available data on the prevalence of trauma-associated mental disorders among South Sudanese in different settings to gain better understanding of the impact of war trauma in this population.

Methods: Guided by the new (2020) Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement, we conducted a systematic review and meta-analysis of all studies published from 1981 to 2021.

Factors Associated with Mental Health Service Use Among Children with ADHD from Adolescence to Early Adulthood.

Childhood attention-deficit/hyperactivity disorder (ADHD) is common and is associated with lifelong adverse outcomes. Little is known about factors associated with mental health service use (MHSU) among children with ADHD from adolescence to early adulthood. This retrospective cohort study aims to investigate factors associated with MHSU among children with ADHD from adolescence to early adulthood using secondary data from Waves I to III of the National Longitudinal Study of Adolescent Health (n = 554).

The moderating role of depression in the association between hypertension during pregnancy and birth outcomes.

Objective: Investigate how hypertension during pregnancy (HDP) and depression during pregnancy (DDP) independently and jointly affect infant birth outcomes.

Methods: This population-based, retrospective cohort study included a sample of 68,052 women who participated in PRAMS 2016-2018 survey. Poisson regression was used for adjusted relative risks (aRRs).

Racial/Ethnic Differences in the Association Between Food Security and Depressive Symptoms Among Adult Foreign-Born Immigrants in the US: A Cross-Sectional Study.

Foreign-born immigrants are at greater risks of both food insecurity and depressive symptoms, while the association between the two has yet to be elucidated. Our sample includes 6,857 adults aged 20 years and older from the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2016. Multivariable logistic regression was used to examine whether the association between food security and depressive symptoms varies across race/ethnicity among US foreign-born immigrants.

Gestational Age of Delivery in Pregnancies Complicated by Diabetes.

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. 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.

Driving Factors of Preterm Birth Risk in Adolescents.

 We examined rates of spontaneous and indicated preterm births (S-PTB and I-PTB, respectively) and clinical risk factors for PTB in adolescents.  This is a population-based, retrospective cohort using 2012 U.S.

Pregnancy Outcomes after Preeclampsia: The Effects of Interpregnancy Weight Change.

Objective: This study aimed to examine the effects of interpregnancy weight change on pregnancy outcomes, including recurrent preeclampsia, preterm birth, small-for-gestational age (SGA), large-for-gestational age (LGA), and cesarean delivery, among women with a history of preeclampsia. We also evaluated whether these associations were modified by prepregnancy body mass index (BMI) category in the first pregnancy (BMI < 25 vs. ≥25 kg/m) and if associations were present among women who maintained a healthy BMI category in both pregnancies.

Racial disparities in U.S. maternal influenza vaccine uptake: Results from analysis of Pregnancy Risk Assessment Monitoring System (PRAMS) data, 2012-2015.

Background: Pregnant women are at increased risk of hospitalization, serious complications, poor pregnancy outcomes, and mortality from influenza. Prior research suggests that there are racial/ethnic disparities in vaccination coverage and that a healthcare provider vaccination recommendation is associated with significantly higher vaccine uptake than without such a recommendation. The purpose of this study is to examine racial/ethnic disparities in healthcare providers' recommendations for pregnant women to receive the influenza vaccine and in vaccine uptake.

Effect of interpregnancy interval after a first pregnancy complicated by placental abruption, on adverse maternal and fetal outcomes in a second pregnancy.

For women who suffer from abruption in the first pregnancy, the extent to which birth spacing has an impact on maternal and fetal outcomes in a second pregnancy remains unclear. To examine the effect of interpregnancy interval (IPI) after a first pregnancy complicated by placental abruption, on adverse maternal and fetal outcomes in a subsequent pregnancy. This was a population-based retrospective cohort study using maternally-linked Missouri birth registry from 1989 to 2005 ( = 2069).

The Difference in Sibling Birthweight and Neonatal Death: A Population-Based Cohort Study.

Background: There has been a call for customized rather than population-based birthweight standards that would classify smallness based on an infant's own growth potential. Thus, this study aimed to examine the association between the difference in sibling birthweight and the likelihood of neonatal death among second births in a U.S.

Ambient air pollution the risk of stillbirth: A prospective birth cohort study in Wuhan, China.

Background: Recent studies suggest that ambient air pollution exposure during pregnancy is associated with stillbirth occurrence. However, the results on the associations between ambient air pollutants and stillbirths are inconsistent and little is known about the gestational timing of sensitive periods for the effects of ambient air pollutants exposure on stillbirth.

Objective: This study aimed to examine whether exposure to high levels of ambient air pollutants in a Chinese population is associated with an increased risk of stillbirth, and determine the gestational period when the fetus is most susceptible.

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.

Sex and age differences in the associations between sleep behaviors and all-cause mortality in older adults: results from the National Health and Nutrition Examination Surveys.

Objective: Our aim was to examine sex- and age-specific relationships of sleep behaviors with all-cause mortality rates.

Methods: A retrospective cohort study was conducted among 5288 adults (≥50 years) from the 2005-2008 National Health and Nutrition Examination Surveys who were followed-up for 54.9 ± 1.

Diet quality and sleep quality among day and night shift nurses.

Aims: To determine whether night shift workers have a poorer diet quality and sleep quality when compared with day shift nurses.

Background: There is a dearth of research investigating the association between diet quality and sleep quality of day and night shift nurses.

Methods: Data on nurses (n = 103) working either a day or night shift from two Midwestern hospitals were obtained from August 2015 to February 2016.

Geographic variability in gestational weight gain: a multilevel population-based study of women having term births in Florida (2005-2012).

Purpose: We examined the extent of geographic variability in gestational weight gain (GWG), identified areas where women have suboptimal GWG, and evaluated whether individual- and area-level factors account for such variability.

Methods: We conducted a population-based cohort study including 1,385,574 women delivering term, singleton, and live births in Florida. We used a Bayesian, structured additive regression with a spatial function to analyze data from Florida's birth certificates (2005-2012) and ZIP code tabulation areas (ZCTAs; 2010 Census).

Gestational Weight Gain in the First Two Pregnancies and Perinatal Outcomes in the Second Pregnancy.

Background: Gestational Weight Gain (GWG) below or above the Institute of Medicine (IOM) recommendations increases the risk of adverse pregnancy outcomes. However, it remains unknown whether the risk of adverse outcomes is affected by GWG in a previous pregnancy. We examined associations between GWG in the index (second) pregnancy and pregnancy outcomes, including preterm delivery and small for gestational age (SGA), while taking into consideration GWG in the first pregnancy.

The Effects of Race and Ethnicity on the Risk of Large-for-Gestational-Age Newborns in Women Without Gestational Diabetes by Prepregnancy Body Mass Index Categories.

Objectives Children born large for gestational age (LGA) are at risk of numerous adverse outcomes. While the racial/ethnic disparity in LGA risk has been studied among women with Gestational Diabetes Mellitus (GDM), the independent effect of race on LGA risk by maternal prepregnancy BMI is still unclear among women without GDM. Therefore, the objective of this study was to assess the association between maternal race/ethnicity and LGA among women without GDM.

Symptoms of anxiety and depression during pregnancy and their association with low birth weight in Chinese women: a nested case control study.

This study is a nested case control study from a population-based cohort study conducted in Wuhan, China. The aim is to estimate the association between symptoms of depression during pregnancy (DDP), anxiety during pregnancy(ADP), and depression with anxiety during pregnancy (DADP) and low birth weight (LBW) and to examine the extent to which preterm birth (PTB) moderates these associations. Logistic regression analyses were used to model associations between DDP, ADP, and DADP and LBW.

Hourly peak PM concentration associated with increased cardiovascular mortality in Guangzhou, China.

Hourly peak concentration may capture health effects of ambient fine particulate matter pollution (PM) better than daily averages. We examined the associations of hourly peak concentration of PM with cardiovascular mortality in Guangzhou, China. We obtained daily data on cardiovascular mortality and hourly PM concentrations in Guangzhou from 19 January 2013 through 30 June 2015.

Neighborhood Conditions and Psychosocial Outcomes Among Middle-Aged African Americans.

Objective: We examined associations between observed neighborhood conditions (good/adverse) and psychosocial outcomes (stress, depressive symptoms, resilience, and sense of control) among middle-aged and older African Americans.

Methods: The sample included 455 middle-aged and older African Americans examined in Wave 10 of the African American Health (AAH) study. Linear regression was adjusted for attrition, self-selection into neighborhoods, and potential confounders, and stratified by the duration at current address (<5 vs ≥5 years) because of its hypothesized role as an effect modifier.

Age at First Birth and Psychiatric Disorders in Low-Income Pregnant Women.

Background: Young maternal age at first birth has been associated with poor mental health. However, few studies directly compared the prevalence of psychiatric disorders among adolescent versus adult mothers at first birth using a comprehensive diagnostic tool. This study examined the association between age at first birth and 22 current and lifetime psychiatric disorders in a cohort of low-income pregnant women.

Racial/Ethnic Differences in the Correlates of Mental Health Services Use among Pregnant Women with Depressive Symptoms.

Objectives To examine correlates of lifetime mental health services (MHS) use among pregnant women reporting prenatal depressive symptoms by race/ethnicity. Methods This cross-sectional population-based study included 81,910 pregnant women with prenatal depressive symptoms using data from the Florida Healthy Start prenatal screening program (2008-2012). Multivariable logistic regression was conducted to ascertain adjusted odds ratios and corresponding 95 % confidence intervals for racial/ethnic differences in the correlates of lifetime MHS use.

Changes in Body Mass Index and the Trajectory of Depressive Symptoms Among Rural Men and Women.

Purpose: This study examined the association between body mass index (BMI) changes over time and the risk of elevated depressive symptoms in a cohort of Midwestern rural adults.

Methods: The longitudinal study used data from a telephone survey in 2005 including 1,475 men and women enrolled in the Walk the Ozarks to Wellness Project from 12 rural communities in Missouri, Arkansas, and Tennessee. Multilevel random intercept mixed models were used to estimate adjusted odds ratios (aOR) and 95% confidence intervals (CI) for the association between BMI calculated from self-reported height and body weight and elevated depressive symptoms, adjusting for sociodemographic, behavioral, and medical variables.
