Abstract:

Sleep is an important part of human health and life. Worldwide, decreased sleep duration was a common problem among adolescents. Insufficient sleep contributes to academic, behavior, mood, and health problems in childhood, that creates a big impact on the future. Decrease sleep and its effect on BMI of children is a focus of many studies globally. OBJECTIVE: To determine the association of decreased sleep duration and body mass index (BMI) of adolescents residing at Barangay 143, Caloocan City. METHODOLOGY: Cross-sectional analytical design was used in this study. The study was conducted at Barangay 143, Caloocan City. A total of 70 adolescents ages 10-19 years old were selected via simple random sampling technique to participate in the study. Exclusion criteria were those who have medical conditions that can adversely affect BMI, previously hospitalized, have infectious diseases, and those who had recent intake of medications that can affect metabolism (eg. corticosteroids). Subjects were given 3 sets of questionnaires, and were categorised as adequate or inadequate sleepers, adequate or inadequate physical activity, and no mental health disorder or has mental disorder. Weight and height were recorded using standard weighing scale, and tape measure to compute for each subject’s BMI. RESULTS: Results showed that thirty-six percent (36%) of the subjects had adequate sleep, and 64% had inadequate sleep. Results also showed that there was no significant association between sleep duration, and BMI among adolescents, with p-value of 0.06. However, specific analysis showed that there was a significant difference in the proportion of subjects with extreme BMI among those with adequate and inadequate sleep. Multivariate analysis of data on the predictors of BMI showed that increasing age was a significant predictor of BMI(p-value <0.05), but inadequate sleep failed to produce a significant association. Crude OR of sleep duration and BMI showed that inadequate sleep has a higher odds of being underweight (OR 2.64), but was not statistically significant. Use of social media was the most common reason for subject’s sleeping late at night. CONCLUSION: Decreased sleep duration appears to have no direct association with BMI.
