Assessing Sleep Architecture in Rural Eastern Cape Villagers of South Africa Using OURA Ring Data.

ABSTRACT:

Objectives

To examine the sleep architecture (proportion of Light, Rapid Eye Movement (REM), and Deep Sleep) of rural villagers using noninvasive, wearable ŌURA rings.

Methods

From June to August 2023, we collected sleep data from 30 participants (16 men, 14 women, 370 nights) using ŌURA rings. Regression models were used to investigate the effect of gender, age, household size, livestock presence, and temperature on sleep patterns and sleep architecture.

Results

Average Total Sleep Time (TST) in the community was 7.6 h (SD: 1.01). Average proportion (%) Light Sleep was 59.9%, % REM Sleep was 17.9%, and % Deep Sleep was 22.2%. Men who cared for livestock had significantly higher % Light Sleep and lower % REM sleep compared to men who did not have livestock. Presence o
