ABSTRACT

OBJECTIVE: To document sleep duration and sleep quality among a sample of Marshallese adults and to examine if sleep duration and quality are associated with type 2 diabetes, body mass index (BMI), and self-reported health in the Marshallese population.

DESIGN: Cross-sectional analysis of a staff-administered survey.

SETTING: Thirty Marshallese churches in Arkansas and Oklahoma.

PARTICIPANTS: The study includes 378 Marshallese participants, 56.6% female, with a mean age of 42.4 years (±11.6). Recruitment was limited to participants who were considered overweight, with a BMI >25 kg/m2.

MEASURES: Staff-administered surveys were used to collect data on sleep duration, sleep quality, and self-reported health. Clinical measures were collected by trained research personnel using standard tools and protocols. Kruskal-Wallis tests, Spearman’s correlations, and nonparametric tests of trends were used to evaluate differences in HbA1c, BMIc, and self-reported health by sleep duration and quality. Multivariable analyses were used to test the associations, controlling for sociodemographic factors.

RESULTS: Fifty-four percent of the participants reported something other than normal sleep duration and 52.4% reported at least 1 night of difficult or interrupted sleep in the previous 2-week period. Longer sleep duration was associated with lower HbA1c and poorer sleep quality was associated with higher HbA1c. Poor sleep quality was associated with lower self-reported health. However, neither sleep duration nor quality was associated with BMI. The associations were found independent of sociodemographic factors.

CONCLUSION: This is the first study to document sleep duration and sleep quality, as well as the first study to examine the relationship between sleep and HbA1c, BMI, and self-reported health in Marshallese adults with a BMI >25 kg/m2. This research will be used to help develop sleep interventions to address type 2 diabetes health disparities in the Marshallese community.

Ebola Survivor Infected Years Ago May Have Started New Outbreak

Genetic sequences of virus samples from the current patients were compared to those from the 2014-16 outbreak and were found to be so similar that they had to be closely related, researchers said. The report, posted online on Friday, involved researchers from the Guinea Ministry of Health, other labs in […]
