Survey on Nutritional Status and Analysis of Related Factors Among Middle School Students in Changsha

Objective To investigate the nutritional status of middle school students in Changsha and the related factors, and to provide scientific evidence for exploring measures for intervention. Methods Four middle schools in Changsha urban area were randomly selected and their students aged 11 to 18 years were recruited to measure the body height and weight, and the nutritional status was assessed by the method of weight for height. Results There were higher prevalences of obesity(14.0%), underweight(40.9%), and malnutrition(5.6%), but an unreasonable lower rate of normal body weight in Changsha adolescents in 2006. The ratios of obesity(17.8% vs 10%, P<0.001 ), underweight(43.1% vs 38.6%, P<0.001) and malnutrition(7.0% vs 4.1%, P<0.001) were significantly higher in boy students than that of girl students. Conclusion The prevalences of obesity and malnutrition are so severe that scientific and effective measures of intervention should be taken to control the disadvantageous complexion.
