【Abstract】 Objective To analyze the changes in nutrition status of Guangxi Zhuang and Han students during 1995-2000 in order to provide a scientific basis for drawing up plans for improving nutrition status of children and youths in this area. Methods Nutritional screening was made in 8 groups of Guangxi students divided according to race, habitation and sex by using the new revised Chinese standards of weight for height and height for age. Dynamic changes in their nutrition status between 1995 and 2000 were analyzed. Results The nutrition status of Guangxi students was improved significantly in the past five years. The prevalence rate of malnutrition decreased evidently, especially in urban students of Zhuang nationality. However, regardless of race, rural students had still higher prevalence rate of malnutrition than their national counterparts, especially those in developed areas, and meanwhile they showed a 2-3 times higher rate of growth retardation than their national peers, indicating chronic malnutrition being the leading cause of short stature. Besides, the rapid increased rates of obesity and overweight were found among urban students of Han nationality in Guangxi. Conclusions The emphasis of student nutrition improvement should be placed on eliminating stunting and wasting due to malnutrition. On the other hand, more attention should be paid to preventing obesity and overweight.更多还原
