为了分析全国七岁汉族小学生营养状况,并为分地区制定营养改善干预措施提供依据,本文采用NCHS标准为参照值,作年龄别身高,年龄别体重,身高别体重营养状况的评价。结果表明:城乡男女各群体中营养不良儿均占30％左右,但大多数为轻度。西南,中南等地区身高发育迟滞者相对集中。我国学童中以低体重为主要表现的营养不良问题最为突出。超重和肥胖在部分地区患病率增长迅猛,应引起高度重视。建议营养不良的预防重点应放在农村,尤其是西南和中南地区;肥胖的预防和干预,重点应放在城市。
In order to analyze the nutritional status of Han nationality primary school students aged seven years in China and to provide the basis for formulating nutritional improvement interventions in different regions, this paper uses the NCHS standard as the reference value to evaluate the nutritional status of different height, age and body weight. The results showed that malnutrition among men and women in urban and rural areas accounted for about 30%, but most were mild. Southwest, South Africa and other regions of height retardation are relatively concentrated. The problem of malnutrition, which is mainly manifested by low weight in our school children, is most prominent. Overweight and obesity in parts of the rapid increase in prevalence should be given high priority. It is recommended that the prevention of malnutrition should be focused on rural areas, especially in the southwest and south-central regions; prevention and intervention for obesity should focus on cities.
