目的了解孕产妇缺铁性贫血发病率,寻找影响孕产妇缺铁性贫血的有关因素。方法采用统一的方法进行调查问卷和血常规实验室检查,应用非条件Logistic回归对贫血的影响因素进行分析。结果 2 405例被调查对象中汉族2 115例(87.94%),回族265例(11.02%),其他少数民族25例(1.04%);贫血者(Hb〈110 g/L)630例,占26.20%。其中30~40岁孕产妇贫血占25.89%(435/1680),回族孕产妇患病率18.87%(50/265),已婚者患病率26.05%(620/2380),银川市常住人口患病率26.63%(450/1680),农民、家庭主妇、暂无职业者患病率分别为:34.15%(140/410)、38.46%(150/390)、27.27%(120/440),为高发人群。孕产妇的怀孕年龄、民族对患病率发生有统计学意义。孕次、流产次数、孕期、膳食结构为孕产妇缺铁性贫血的危险因素,民族、婚姻状况、地域、产检次数、月经量、避孕节育措施知识了解为其保护性因素。结论孕产妇缺铁性贫血患病率偏高,其年龄、婚姻状况、产检次数、民族、职业、孕次、孕期、膳食结构等对孕产妇贫血患病率有一定影响关系,进行有关的健康宣教可以减少其风险。
Objective To understand the prevalence of maternal iron deficiency anemia and find out the relevant factors.Methods A unified method was used to conduct questionnaires and routine blood tests,and the influencing factors of anemia were analyzed by unconditional Logistic regression. Results Among the 2 405 subjects,2 115( 87. 94%) were Han,265( 11. 02%) were Hui and 25( 1. 04%) were from other ethnic minorities.630 cases were in anemia( Hb110 g/l),accounting for 26.20 %.The maternal aged 30-40 years old accounted for 25.89%( 435/1 680),the Hui maternal was 18. 87%( 50/265) and married maternal was 26. 05%( 620/2380). The resident of Yinchuan was 26. 63%( 450/1680). The peasants,housewives and non-working people were 34. 15%( 140/410),38. 46%( 150/390) and 27. 27%( 120/440),respectively.They were in the high incidence.The pregnancy ages and ethnic background for prevalence rates were statistically significant. The number of pregnancy,abortion,pregnancy stages and dietary structure were risk factors for maternal iron deficiency anemia. The ethnic background,marital status,region,antenatal care,menstrual flow and contraceptive measures were protective factors. Conclusion The prevalence rate of maternal iron deficiency anemia was high.Their age,marital status,antenatal care,ethnic background,occupation,pregnancy times,pregnancy stages and dietary structure have an impact on the prevalence of maternal anemia.The health education can reduce the risk.
