ecently, we reported that the association between sleep duration and obesity. Also, the vitamin D deficiency is common in
elderly population and is associated with obesity. We analyzed the combined interaction between serum level of vitamin
D and sleep duration on the obesity-related variables among 3,757 Korean elderly population using Korean National Health
and Nutrition Examination Survey. The average age was 71.61 years (65~97 years) and serum vitamin D was 19.03ng/mL
(4.11~53.54ng/mL). The obesity-related variables, such as BMI (P=0.001), WC (P=0.014), FG (P=0.016) and TG (P=0.019),
were significantly higher in vitamin D insufficient than in sufficient group. There were significant difference in interaction
between serum level of vitamin D and sleep duration on obesity-related variables, such as BMI (P=0.004) and risk for obesity
(P<0.001). Subjects who were vitamin D insufficient status and short sleep duration had higher BMI than those who were
vitamin D sufficient status and proper sleep duration. Using vitamin D sufficient status and proper sleep duration as a reference,
the subjects with vitamin D sufficient status showed no difference in the risk of obesity, regardless of sleep duration. However,
among subjects who were vitamin D insufficient status, the risk of obesity showed increased trend with proper sleep duration
compared with short sleep duration [1.293 (95% CI = 1.10-1.657) for proper sleep duration vs. 1.374 (95% CI = 1.066-1.770)
for short sleep duration].
