Introduction: Sleep quality and physical activity can affect the mental and physical health of pregnant women and their babies in utero.
Methods: We investigated the feasibility of objectively assessing sleep quality and physical activity among resource-constrained, pregnant women in urban Lima, Peru. Twenty pregnant women were asked to complete written sleep logs and wear ActiSleep, a wristwatch-like device that records sleep quality (consecutive minutes of uninterrupted sleep) and physical activity (steps), for seven consecutive days. Sociodemographic data and pregnancy characteristics were also collected.
Results: Of twenty women, 13 (65%) had sufficient data collected for analysis. The mean age of study participants was 26.3 years (SD = 3.9), with a mean sleep duration of 6.9 h (SD = 1.4). The median time for sleep onset was 21:15. The mean time for sleep latency was 17.3 min; and wake after sleep onset was 116 min. The mean number of awakenings was 20.4 (SD = 6.7); and sleep efficiency was 77.9%. For physical activity, participants averaged of 6,029 steps per day (SD = 3,087).
Discussion: Objective assessment of sleep quality and physical activity among pregnant women in a resource-constrained setting was promising, despite modest data collection completeness. Wearable technology could be used in health interventions to improve sleep quality and physical activity among this population.
