Daytime napping linked to increased diabetes risk

Daytime napping, regardless of duration is associated with an increased risk for diabetes; however, the risk is highest with a nap duration of more than 90 minutes, according to study findings published in Journal of Diabetes.
Chongqi Jia, MD, of the department of epidemiology at Shandong University in China, and colleagues evaluated data from the 2011 to 2012 China Health and Retirement Longitudinal Study on 12,277 Chinese adults (mean age, 59.2 years; 5,920 men) to determine the association between prediabetes and napping.
Participants reported daytime napping through a questionnaire and were divided into non-nappers (0 minutes), short nappers (< 30 minutes), moderate nappers (31 to 90 minutes) and long nappers (> 90 minutes).
Overall, nearly half (46.61%) of participants reported no napping, 16.76% reported short napping duration, 25.44% reported moderate napping duration, and 11.19% reported long napping duration.
The prevalence of diabetes and prediabetes was higher in the napping groups compared with the no napping group. Short nap duration (OR = 1.42; 95% CI, 1.05-1.91), moderate nap duration (OR = 1.31; 95% CI, 1.05-1.65) and long nap duration (OR = 1.72; 95% CI, 1.31-2.25) were all associated with an increased risk for diabetes compared with no napping in the univariate model. Any duration of afternoon napping was associated with a risk for prediabetes; however, moderate napping duration was not statistically significant.
The risk for diabetes was 20% higher in the short nap duration group, 18% higher in the moderate nap duration group and 61% higher in the long nap duration group compared with the no nap group.
“Our results suggest that elderly people with long napping habits may be a high-risk population for diabetes, and we should pay more attention to this population for diabetic prevention and treatment,” the researchers wrote. “Further physiological and cohort studies are necessary to confirm our findings and demonstrate potential mechanisms.” – by Amber Cox
