Inactivity, Obesity and Mental Health in the Spanish Population from 4 to 15 Years of Age

Abstract

Background: An active lifestyle and a good weight status are two major health determinants from a public health perspective. Aim: To evaluate the degree of association between physical activity, weight status and the emotional and mental health of Spanish schoolchildren. Method: Mental health status was assessed through the Strengths and Difficulties Questionnaire (SDQ), also leisure time physical activity and body mass index (BMI) in a total of 6 803 children from 4 to 15 years participating in the Spanish National Health Survey 2006. The degree of association between. these variables was estimated by a multinomial logistic regression analysis. Results: Among sedentary schoolchildren are more common mental health problems (OR 2.10), emotional problems (OR 1.84), conduct problems (OR 1.53), problems with peers (OR 2.35) and social relationship difficulties (OR 1.36). Obesity is associated with poor general mental health (OR 1.58), and obese schoolchildren show more often emotional problems (OR 1.52) and problems with peers (OR 2.43). Conclusions: In the Spanish schoolchildren, a healthy BMI is associated with increased mental well-being, although an active lifestyle is the best indi ator of a good mental health status.
