【摘要】 目的:探讨合理的膳食结构与儿童成长发育中身高、体质量、血红蛋白(hemoglobin,Hb)的关系。方法:按照常规营养调查法分别于1989和1999年对泰安市同一所幼儿园的163名和175名儿童进行膳食调查、体格检查及生化检验。结果:1999年的膳食结构更趋于合理。蛋白质、维生素B1、烟酸供给量均已达到或超过中国营养学会推荐每日膳食中营养素供给量(recommendeddietaryallowance,RDA);而钙(5岁男童为423mg,女童为416mg;6岁男童为448mg,女童为422mg)及维生素当量(5岁男童为448mg,女童为442mg;6岁男童为546mg,女童为542mg)仅约为RDA的50%及70%,还存在不足。1999年通过膳食结构改善后儿童身高、体质重、血红蛋白犤6.0～6.9岁男童分别为(118.5±4.7)cm,(21.2±4.1)kg,(131.5±8.8)g/L犦均较1989年犤(98.0±4.2)cm,(16.0±1.6)kg,(121.4±7.4)g/L犦有明显增加(t=4.4～20.8,P<0.01);贫血率由10年前的17.5%降至4.7%。结论:合理的膳食结构能使儿童发育过程中身高、体质量明显提高,贫血症状得到改善。更多还原
