P>Title.
Obesity among adolescents: sedentary leisure time and sleeping as determinants.
Aim.
This paper is a report of a study of the association between various risk factors and obesity among adolescents.
Background.
Over the past 30 years, the prevalence of overweight and obesity in children and adolescents has nearly tripled. Physical inactivity, unbalanced diet, and unhealthy lifestyles may cause lifelong obesity.
Methods.
A representative, national cross-sectional study was carried out between 2006 and 2007 with 40 middle high schools with 384 classes. We used a three-stage stratified systematic sampling design with a probability proportionate to the size from the northern, middle, southern, and eastern areas in Taiwan. Questionnaires were completed by 8640 students (51 center dot 7% boys and 48 center dot 3% girls) aged between 13 and 16 years.
Results.
Obesity was identified in 7 center dot 2% of the participants and 16 center dot 1% were overweight. Using stepwise logistic regression, we found that those whose fathers or mothers were obese, watched television for more than 2 hours/day on weekdays and slept for less than 7 center dot 75 hours/day at weekends had a statistically significantly greater risk of obesity (females: ORs = 3 center dot 4, 4 center dot 2, 1 center dot 8, and 4 center dot 2, respectively; P < 0 center dot 05; boys: ORs = 2 center dot 3, 1 center dot 7, 1 center dot 4, and 1 center dot 6, respectively; P < 0 center dot 05).
Conclusion.
To help prevent obesity, strategies are needed to decrease adolescents sedentary leisure time and help them have sufficient sleep. Nurses can play a key role in health promotion in relation to childhood and adolescent obesity.
