用分层随机抽样方法对福建省10个县市的17196例0～5岁儿童进行营养不良调查。以年龄的作重分度并按全国九市男童标准衡量。结果显示：（1）福建省营养不良患病年轻度为24.67％，中度6．21％，重度0．92％，因地理位正、经济状况的不同，城市、平原、沿海山区各层的营养不良患病率由低到高，且存在显著性差异（P＜0．01）。（2）0～5岁营养不良患病率变化趋势为0～8个月较低，8～18个月最高，尔后下降。（3）父母文化程度、职业、婴儿喂养方式、辅食添加和疾病等13项因素影响营养不良的发生。因此，作者建议防治营养不良重点要放在边远贫困地区，并提出相应防治措施。
A stratified random sampling method was used to investigate malnutrition among 17,196 children aged 0 ~ 5 in 10 counties and cities in Fujian Province. Re-indexed by age and measured by boys in nine cities in the country. The results showed that: (1) The prevalence of malnutrition in Fujian province was 24.67%, moderate 6.21%, and severe 0.92% respectively. Due to the difference in geographical location and economic status, The prevalence of malnutrition was from low to high, and there was a significant difference (P <0.01). (2) The prevalence of malnutrition between 0 and 5 years old was lower from 0 to 8 months, highest from 8 to 18 months and then decreased. (3) The incidence of malnutrition is influenced by 13 factors such as parents’ educational level, occupation, infant feeding mode, supplementing food and illness. Therefore, the author suggests that the focus of prevention and treatment of malnutrition should be put on remote and impoverished areas and put forward corresponding prevention and control measures.
