本文利用身高标准体重法（全国标准）评价广西2市4县4乡21所中小学12339名7－18岁青少年儿童的现时营养状况，乡青果表明总的营养不民率为39．06％，营养过剩（超重、肥胖）率为4.04％，均高于本地报道的资料[1]。女生营养不良率为45．85％明显高于男生的33．58％（P＜0．01）；城市学生的营养不良率（38．32％）高于县城（33．50％）和乡村（29.61％）学生（P＜0．01）。表明城市青少儿的体格发育较乡村有瘦长的趋势。 This article uses the height standard weight method (national standard) to evaluate the current nutritional status of 12339 adolescents aged 7-18 in 21 primary and secondary schools in 4 counties, 4 townships and 2 towns in Guangxi. The results show that the overall nutrition rate is 39.06% The prevalence of overnutrition (overweight and obesity) was 4.04%, both higher than those reported locally [1]. The rate of malnutrition among girls in urban areas was 45.85%, significantly higher than that in boys (33.58%) (P <0.01). The rate of malnutrition in urban students was higher than that in urban areas (33.50%) and rural areas 29.61%) students (P <0.01). It shows that the physical development of urban youth tends to be more slender than that of rural areas.
