Abstract

Childhood is a crucial period in life for the acquisition of healthy lifestyles, having ahuge influence on risk factors for chronic diseases. The current lifestyle changes have increased the risk for obesity. One of these changes is sleep duration. There is evidence that children are sleeping less than previous generations, and it has been suggested that this may be contributing to the increasing prevalence of obesity. Our aim is to assess the relationship between sleep duration and obesity, including some other related behaviors. Material and methods A representative sample of 2838 children of 8 years, living in Tuscany Region (Italy) was investigated in one nutritional surveillance study run in 2002. Nutritional status was evaluated by weight and height measures collected by standardized personnel, using IOTF reference methods. Lifestyles were obtained by questionnaire submitted to parents. Results The mean night sleep time for our sample was 9.3±0.8 hours, quite 1 hour less than the recommended time for this age. An inverse relationship between sleep duration and obesity has been found (p=0.000); showing a 41.9% prevalence of obese and overweight among children who slept less than 8 hours, against a 28.7 % in those who have more than 10 hours of sleeping. The sleep duration could also been related to sedentary behavior and nutritional aspects. Sedentary kids show less sleep duration respected non sedentary ones (9.1±0.8 hours vs 9.4±0.8; p=0.000). At the same time those children who had a short sleep duration (<8 h) report more snacks eating respecting those who sleep >10 h (p<0.001). A higher educational level of the mother has a positive influence on the sleep duration, with increasing values. Conclusions An inverse association between childhood sleep time and BMI has been found. It is also seemed that sleep restriction in childhood is related to the time inactive of the children and the snacks eating with a negative impact on obesity. Due to the educational level of the mothers could have an influence on sleep duration, it seems important to concentrate efforts on their knowledge and awareness improvement.
