Primary outcomePrimary: Sleep Quality Assessment 1 (GSS) — 3.4; 8.1; 5.2 score on a scale
Summary
Sleep is essential to health. Quality of sleep, measure through indexes of sleep, is related to the incidence of obesity, type 2 diabetes, cardiovascular disease, hypertension, and premature death. Sleep pattern changes as people age. They tend to have a harder time falling asleep and more trouble staying asleep than when they were younger. Studies have shown that food/nutrient intake may be associated with sleep duration, quality, and patterns. Singapore's population is aging rapidly and improving their indexes of sleep may result in their health promotion.
