目的 :研究和探讨宁夏农村哺乳期妇女及婴幼儿的铁营养状况。方法 :采用营养状况调查和实验室检测等方法对宁夏农村哺乳期妇女及婴幼儿进行抽样研究。结果 :宁夏农村乳母的Hb均值为 131 5g/L ,Hb异常者比例为 30 2 %。但随着产后时间的延长 ,Hb水平明显回升 (r =0 .832 8,P <0 0 5 )。 0～ 6月婴儿的Hb均值为 118 8g/L ,Hb含量低于 110g/L者 (3月龄以下者以Hb低于 10 0g/L计 )占有较高的比例 (39 2 % )。另外 ,随着哺乳期的延长 ,乳母血清中铁元素含量有显著的增加趋势 (r =0 .182 3,P <0 0 1) ,乳汁中铁元素虽也有所增加 ,但并无显著的统计学意义 (P >0 0 5 )。结论 :在农村加强合理营养方面的宣传教育 ,以提高乳母的有关营养素摄入水平及母乳喂养率 ,改善乳母及婴儿的铁营养状况。
OBJECTIVE: To study and explore the status of iron nutrition in lactating women and infants in rural Ningxia. Methods: The nutritional status of the survey and laboratory tests and other methods in Ningxia rural lactating women and infants were sampled. Results: The mean value of Hb in rural nursery in Ningxia was 131 5g / L and the proportion of abnormal Hb was 30 2%. But with the extension of postpartum time, the level of Hb obviously rose (r = 0.8328, P <0.05). From June to June, the mean Hb of infants was 118.8 g / L, while the Hb content was less than 110 g / L (39.2% of patients under 3 months of age with Hb less than 100 g / L). In addition, with the extension of lactation, lactate serum iron content increased significantly (r = 0.182 3, P <0 0 1), iron in milk, although it also increased, but no significant statistical significance (P> 0 0 5). CONCLUSION: Publicity and education on strengthening reasonable nutrition in rural areas is to raise the level of nutrient intake and breastfeeding rate of nurse, and improve the iron nutrition status of nurse and infant.
