The Relationship Between Lack of Sleep and Excessive Weight

Abstract

Sleep is necessary for the body to function properly, so the duration and quality of sleep are significant for human health. Several studies have found that sleep is vital in regulating physiological functions such as energy balance, appetite, and body weight. Several studies also show increased appetite due to decreased leptin levels and increased ghrelin levels due to lack of sleep. Poor sleep quality reduces activity and results in excess body weight. The aim of this research was to see the relationship between lack of sleep and the incidence of excess body weight at Junior High School of Bakti Mulya 400, South Jakarta, Indonesia. The method used in this research was a correlational descriptive method. The research was conducted on 72 students of Bakti Mulya 400 Middle School. Body height was measured using a microtome and body weight was measured using a weight scale. Body Mass Index is calculated using the formula according to WHO. Respondents were asked to fill out a questionnaire. Data entry and analysis continued using spss 23 program. Based on the results of research on 36 people with a Body Mass Index of 18.5-22.9, 12 people didn’t get enough sleep, and 24 people got enough sleep. Meanwhile, of 36 people with a Body Mass Index > 23, there were 21 people didn't get enough sleep, and 15 got enough sleep. The conclusion from the research results is that sleep duration has a significant relationship with excess body weight, but sleep quality does not have a substantial relationship with excess body weight.
