Gestational weight gain and increased risk of cesarean delivery across body mass index categories.

Background: Unnecessary cesarean delivery can have negative implications for both mothers and infants. In the United States, the proportion of women undergoing cesarean delivery exceeds the acceptable World Health Organization proportion. Reducing cesarean deliveries is a national goal of Centers for Disease Control and Prevention Healthy People 2030, the American College of Obstetricians and Gynecologists, and the Alliance for Innovation on Maternal Health.

Sociodemographic factors associated with prenatal care utilization in Arkansas, United States.

Objectives: This study examines prenatal care utilization differences in Arkansas.

Methods: Birth records data from the National Center for Health Statistics were used. The study population consisted of singleton live births in Arkansas from 2014 to 2022.

Prolonged nightly fasting in older adults with memory decline: A single-group pilot study exploring changes in cognitive function and cardiometabolic risk factors.

Introduction: Older age significantly increases risk for cognitive decline. A growing number of older adults (≥ 65 years) experience cognitive decline that compromises immediate and/or long-term health. Interventions to mitigate cognitive decline are greatly needed.

Health impacts of a remotely delivered prolonged nightly fasting intervention in stressed adults with memory decline and obesity: A nationwide randomized controlled pilot trial.

Objective/goals: Cognitive decline is intricately linked to various factors such as obesity, stress, poor sleep, and circadian rhythm misalignment, which are interrelated in their impact on cognitive health. Irregular food-intake timing further compounds these issues. The practice of prolonged nightly fasting (PNF) may help synchronize food intake with circadian rhythms, potentially mitigating adverse effects of cognitive decline and associated factors.

Behavioral and sociodemographic correlates of sleep duration among children in Samoa.

Objectives: To describe sleep duration, adherence to sleep recommendations, and behavioral and sociodemographic correlates of sleep among Samoan children.

Methods: In a longitudinal cohort study of Samoan children aged 2-9years (n = 481; 50% female), primary caregivers reported usual number of hours of nighttime sleep during 2015, 2017/2018, and 2019/2020 data collection waves. Associations between behavioral and sociodemographic characteristics and sleep duration were assessed using generalized linear and mixed effect regressions.

Characterization of sleep apnea among a sample of adults from Samoa.

Sleep apnea is a global public health concern, but little research has examined this issue in low- and middle-income countries, including Samoa. The purpose of this study was to examine the sample prevalence and characteristics of sleep apnea using a validated home sleep apnea device (WatchPAT, Itamar) and explore factors that may influence sleep health in the Samoan setting. This study used data collected through the ("Good Health") study, which investigated the impact of the body mass index (BMI)-associated genetic variant rs373863828 in on metabolic traits in Samoan adults (sampled to overrepresent the obesity-risk allele of interest).

Prediction of neonatal survival among Pacific Islander preterm births in the US.

Objective: Predicting neonatal survival is essential for targeting interventions to reduce neonatal mortality. Pacific Islanders have been underrepresented in existing prediction tools and have unique, maternal obesity-related risk factors for both preterm birth and neonatal mortality. Using neonatal sex, birth weight, and gestational age, we developed a graphical tool for neonatal survival among Pacific Islander singletons in the United States.

A genome-wide association study of anti-Müllerian hormone (AMH) levels in Samoan women.

Study Question: Can a genome-wide association study (GWAS) and transcriptome-wide association study (TWAS) help identify genetic variation or genes associated with circulating anti-Müllerian hormone (AMH) levels in Samoan women?

Summary Answer: We identified eleven genome-wide suggestive loci (strongest association signal in 19-946163-G-C [ = 2.32 × 10⁻⁷]) and seven transcriptome-wide significant genes ( [all with a < 2.50 × 10⁻⁶]) associated with circulating AMH levels in Samoan women.

Shaping childhood obesity: behavioral and environmental risk factors associated with body mass index trajectories between 2 and 9 years in Samoan children.

Background/objective: Pacific children are at high obesity risk, yet the behavioral and environmental factors that contribute to obesity development in this setting remain poorly understood. We assessed associations between childhood risk factors for obesity with body mass index (BMI) trajectories between ages 2-9 years in Samoa.

Subjects/methods: In a prospective cohort of 485 children from 'Upolu, we measured weight and height at ages 2-4 (2015), 3.

A group prenatal care intervention reduces gestational weight gain and gestational diabetes in American Samoan women.

Objective: The objective of this study was to determine the preliminary effectiveness of an intervention to mitigate adverse pregnancy outcomes associated with pre-pregnancy obesity in American Samoa.

Methods: We enrolled n = 80 low-risk pregnant women at <14 weeks' gestation. A complete case analysis was conducted with randomized group assignment (group prenatal care-delivered intervention vs.

Earlier Bedtimes Mediate the Effect of a Brief Behavioral Sleep Intervention on Children's Weight Status.

Whether the effect of a brief behavioral sleep intervention on child weight status resulted from observed differences in sleep duration and/or bedtimes was assessed. Findings demonstrate that the intervention's beneficial effect on weight status was due to earlier bedtimes, suggesting the potential importance of earlier bedtimes for obesity prevention.

Needs of social isolation, loneliness, and intergenerational interventions in the United States: a scoping review.

Social isolation and loneliness are major health concerns for older adults in the United States. This scoping review examines the effectiveness of intergenerational interventions aimed at reducing social isolation and loneliness among older adults in the United States, specifically through programs that engage university students from healthcare-related fields in one-on-one settings with older adults, as reports of lacking geriatric training of healthcare students causes older adult neglect to persist in the healthcare workforce. The importance of addressing these issues is underscored by significant health risks and substantial economic burdens, with social isolation and loneliness potentially increasing mortality and costing Medicare an estimated $6.

Comparing Gender Congruency in Nonsurgical versus Postsurgical Top Surgery Patients: A Prospective Survey Study.

Background: Gender dysphoria can result in reduced quality of life. Treatments include hormone replacement therapy (HRT) and gender-affirming surgery. Our study compared congruency, satisfaction, and discrimination in patients who underwent top surgery and HRT versus HRT alone.

Noncommunicable disease risk behaviors and protective factors among children in Samoa: Retrospective trend analysis of global school-based health surveys in 2011 and 2017.

Pacific Island countries experience a high prevalence of noncommunicable diseases (NCDs), which may be prevented by reducing risk behaviors and strengthening protective factors in childhood and adolescence. To better inform preventative interventions, our objective was to use publicly available data from the Global School-based Student Health Survey (GSHS), to provide cross-sectional and trend estimates for the prevalence of NCD risk and protective factors among school-aged children in 2011 and 2017 in Samoa. Two waves of cross-sectional data included 4,373 children (51.

Associations between fasting glucose rate-of-change and the missense variant, rs373863828, in an adult Samoan cohort.

Background: The A allele of rs373863828 in CREB3 regulatory factor is associated with high Body Mass Index, but lower odds of type 2 diabetes. These associations have been replicated elsewhere, but to date all studies have been cross-sectional. Our aims were (1) to describe the development of type 2 diabetes and change in fasting glucose between 2010 and 2018 among a longitudinal cohort of adult Samoans without type 2 diabetes or who were not using diabetes medications at baseline, and (2) to examine associations between fasting glucose rate-of-change (mmol/L per year) and the A allele of rs373863828.

The milk study protocol: A longitudinal, prospective cohort study of the relationship between human milk metabolic hormone concentration, maternal body composition, and early growth and satiety development in Samoan infants aged 1-4 months.

Background: Current research suggests that energy transfer through human milk influences infant nutritional development and initiates metabolic programming, influencing eating patterns into adulthood. To date, this research has predominantly been conducted among women in high income settings and/or among undernourished women. We will investigate the relationship between maternal body composition, metabolic hormones in human milk, and infant satiety to explore mechanisms of developmental satiety programming and implications for early infant growth and body composition in Samoans; a population at high risk and prevalence for overweight and obesity.

Screening for Hypertension in adolescents living with HIV: Protocol for a cluster randomized trial to improve guideline adherence.

Background: Although AIDS-related deaths have reduced with increased access to antiretroviral care, cardiovascular disease-related morbidities among persons living with HIV are rising. Contributing to this is the higher incidence of Hypertension among Persons Living with HIV. The duration of exposure to the virus and antiretroviral drugs plays a vital role in the pathogenesis, putting perinatally infected children and adolescents at higher risk than behaviorally-infected ones, supporting the calls for increased surveillance of Hypertension among them.

Accelerometer-Based Estimates of Physical Activity and Sedentary Time Among Samoan Adults.

Background: The prevalence of obesity-related cardiometabolic disease in Samoa is among the highest globally. While physical activity is a modifiable risk factor for obesity-related disease, little is known about physical activity levels among adult Samoans. Using wrist-worn accelerometer-based devices, this study aimed to characterize physical activity among Samoan adults.

Child routines moderate a brief behavioral intervention to enhance sleep in school-aged children.

Objective: To examine whether child routines (the consistency or variation in children's daily routines, household responsibilities, discipline routines, and homework routines) moderated the effectiveness of a brief behavioral intervention to enhance sleep in school-aged children.

Methods: Secondary analysis was conducted with a subset of 66 families with short sleeping (≤9.5 hr/day) children, 8-11 years old (female = 68%; mean age = 9.
