Purpose: A meta-analysis on sleep duration and patterns in patients with diabetes in China.
Design and methods: Two investigators independently carried out a systematic literature search in both international and Chinese databases.
Findings: A total of 47 studies with 98 911 patients were included. The pooled mean sleep duration was 7.15 hours/day in patients with diabetes and 7.49 hours/day in healthy controls. The estimated percentage of short sleep duration of less than 6 hours/day was 23.0% in patients with diabetes and 12.3% in healthy controls, while the proportion of short sleep duration of less than 7 hours/day was 38.0% in patients with diabetes and 14.1% in healthy controls.
Practice implications: Short sleep duration was common in Chinese patients with diabetes.
