ABSTRACT
Introduction: Sleep is essential for life and proper organism process functioning. Numerous studies had shown the time we spend sleeping has decreased significantly in the last two decades. This reduction has been described in both adults and children. There are many evidences of the effect of sleep restriction in humans; we know that adversely affects behaviour, cognition, immune system, food intake, etc. Childhood is particularly vulnerable to the harmful effects of sleep restriction; affects the aspects already mentioned and also harms development. Sleep restriction also increases appetite which can bring the subject to overweight or obese.
Objective: The objective of this research was to evaluate the number of sleep hour of Mexican children and adolescents and determine their impact on body mass index.
Method: It is an analytical, transversal and observational study.
Results: The result showed a decreased of the total sleeping time recommended for each group; children between 8-11 years old sleep an average of 8.8 hours; while children entre 12 and 14 sleep 8 hours. The sleeping time differs from weekdays to weekend, 10.3 and 10 respectively. A significant negative correlation between body mass index and total sleep time was observed in children between 12 and 14 years old.
Conclusions: With this approach we can conclude that Mexican children sleep less than necessary. Finally in children between 12 and 14 years, this sleep restriction is associated with overweight and obesity.
