Excess body weight and obesity associated with sleep duration and it’s quality among the population aged 25—44 years

Resultado clave

Men sleeping 5–6 hours had 2.29 times higher odds of overweight/obesity than those sleeping 9–10 hours (p=0.04), with sleep duration linked to increased obesity risk.

Resumen

Objective. To establish the association of anthropometric indicators and duration and quality of sleep among young residents (25—44 years) in Novosibirsk. Materials and methods. Screening of a representative sample of the population aged 25—44 of the Oktyabrsky district of Novosibirsk was carried out on the basis of the Research Institute of Internal and Preventive Medicine — branch of the Institute of Cytology and Genetics, Siberian Branch of the Russian Academy of Sciences in 2013—2017 (403 men, mean age 34±0.4 years, response was 71%, and 531 women, mean age 35±0.4 years, response — 72%). The screening examination program is implemented in accordance with the protocol of the WHO MONICA1 international program. Results. Men with sleep duration of 5—6 hours had a higher median body mass index (BMI) of 26.98 kg/m2 than men with 9—10 hours of sleep — 24.43 (p=0.036). Median waist-to-hip ratio (WC/HC) of 0.91 was higher in men with 6 hours of sleep than with 8 hours — 0.90 (p=0.049). In the multifactor model, a probability of overweight or obesity was 2.29 times higher in men with sleep duration of 5—6 hours (p=0.04) than in those who slept 9—10 hours and had a low close contact index (OR=4.6; p=0.017). This probability increased by 2.13 times (p=0.048) with the increase in age by 1 year. The chance of being overweight or obese was higher in subjects of both sexes with a low close contact index (OR=2.45; p=0.025) and low social connection index (OR=0.37; p=0.019). With each year the chance increased by 64% (OR=1.64; p=0.033). Statistically significant differences in BMI, WC/HC and self-assessment of sleep quality for individuals of both sexes as well as in men and women separately were not identified. Conclusion. The association between the occurrence of overweight or obesity and short duration of sleep has been established.
