Description
Nearly three in ten Kazakh adults sleep poorly, finds a 2026 national survey led by Yerlan Ismoldayev. Interviewers collected Pittsburgh Sleep Quality Index data from 5,872 adults aged 18 to 69 during the first survey wave after the country adopted a single time zone.
The weighted share with poor sleep was 28.1%, driven mainly by trouble falling asleep and disturbed nights rather than medication use. Odds ran higher for women, older adults, city dwellers, smokers, heavy drinkers, and people with diabetes. Depressive symptoms carried the strongest link, an adjusted odds ratio of 4.26. Rural residents slept better, and several regions fared worse than the North. The authors frame the results as a baseline for sleep health policy.
