目的了解广西城乡6~17岁少年儿童膳食营养状况。方法从2002年“中国居民营养与健康状况调查”的广西调查数据库中抽取6~17岁少年儿童共929人的膳食摄入资料,分析儿童青少年膳食与营养的现状。结果广西城市少年儿童热能及蛋白质的摄入基本上达DRIs的要求,而农村少年儿童的热能和蛋白质只达到DRIs的76.37%~89.18%和70.02%~75.22%。少年儿童存在严重的乳类摄入不足,城市少儿乳类的平均每日摄入量达中国营养学会推荐的42.19%,而农村少年基本是无乳类摄入。城市少年儿童钙的标准平均每人每天摄入仅达到DRIS的41.25%~43.38%,农村更是仅达到25.69%~28.31%。结论广西儿童少年尤其是农村少年儿童膳食供给不足,营养状况存在明显的缺乏,应加强学校健康教育,科学指导学生健康饮食,合理改善膳食结构,做到均衡营养。
Objective To understand the nutritional status of children aged 6 ~ 17 in Guangxi urban and rural areas. Methods A total of 929 dietary intake data of children aged 6-17 years from Guangxi survey database of 2002 China National Survey on Nutrition and Health Status were collected to analyze the diet and nutrition status of children and adolescents. Results The intake of caloric and protein in urban children and adolescents in Guangxi basically reached the requirements of DRIs, while the heat and protein of rural children reached only 76.37% ~ 89.18% and 70.02% ~ 75.22% of the DRIs in Guangxi. Children and adolescents have serious milk intake deficiencies. The average daily intake of urban children’s milk reaches 42.19% recommended by the Chinese Nutrition Society, while that of rural teenagers is basically non-dairy intake. The standard calcium intake for urban children averaged only 41.25% -43.38% of DRIS per person per day, and only reached 25.69% -28.31% in rural areas. Conclusions Children and adolescents in Guangxi, especially rural children, have inadequate dietary supply and lack of nutrition status. They should strengthen their health education in schools, scientifically guide students to healthy diet, improve their dietary structure rationally, and achieve balanced nutrition.
