Short Sleep Duration as a Risk Factor for Obesity and Gingivitis in Kuwaiti Children
Objectives: It has been shown that insufficient sleep is related to hormonal disturbance and metabolic disruption leading to weight gain and obesity independent of the amount of caloric intake. Insufficient sleep triggers inflammation in different body organs. In this study we assessed short sleep duration as a potential risk factor for obesity and gingivitis among a cohort of Kuwaiti children.
Methods: Cross sectional data were collected from 8,275 children, 10-12 years old, from 185 elementary schools, representing the 6 governorates of Kuwait. Body weight analysis, sleep evaluation interviews, oral examination, and life style assessments were conducted by calibrated examiners in the selected schools.
Two outcomes were assessed using 2 multiple linear regression models. The first model examined waist circumference as the outcome representing abdominal obesity, with sleep duration as the main independent variable. The second outcome examined percentage of red gingival sites with sleep duration as the independent variable.
Other explanatory variables and potential confounders were considered in the 2 models to identify factors related to obesity and gingivitis.
Results: There was a significant association between increased waist circumference and short sleep duration (B= -0.4, P<0.005, CI= -0.6, -0.14), adjusting for gender and frequency of snacking. No significant association was found between trouble in breathing during sleep and obesity (B= 0.5, P >0.05, -0.8, 1,9) . We found a significant association between increased percentage of sites with gingivitis and short sleep duration (B= - 0.4, P<0.005, CI = -0.7, -0.13), adjusting for gender and frequency of snacking. TV viewing was significantly associated with both obesity and gingivitis (B= 0.37, P <0.005, CI= 0.14, 0.6), (B=1.3, P <0.005, CI= 2.1, 0.4), respectively. Gingivitis was positively and significantly associated with increased dental caries (B=0.3, P<0.0001, CI= 0.25, 0.34).
Conclusions: Short sleep duration is significantly associated with increased obesity and gingivitis in Kuwaiti children. Children who spent longer periods of time with screen-based activities were more likely to be obese and have gingivitis.
