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).

Epidemiology of Lymphatic Filariasis Antigen and Microfilaria in Samoa, 2019: 7-9 Months Post Triple-Drug Mass Administration.

The elimination of lymphatic filariasis (LF) as a public health problem remains an ongoing challenge in the Pacific region. This study reports on antigen (Ag) and microfilaria (Mf) prevalence in Samoa in 2019, 7-9 months after the completion of the first round of triple-drug mass drug administration (MDA). It evaluates the effectiveness of the intervention for reducing Ag prevalence to below a 2% threshold, and how this differs between 5-9-year-olds and ≥10-year-olds.

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.
