浙江德清农村社区已婚育龄女性饮茶与贫血的相关研究

目的了解中国浙江农村社区已婚育龄女性贫血状况及饮茶与其关系。方法采用流行病学现况研究设计,整群抽取浙江省德清县4个农村社区,面对面调查上述社区中20～49周岁的社区已婚育龄女性居民1425人。调查内容包括一般情况、健康状况、生活行为方式等。采用氰化高铁法测定血红蛋白。在SPSS11.0中进行数据分析,对于分类变量进行卡方检验;在二分类和多分类Logistic回归模型中检验饮茶与贫血的关联。结果在1425名调查对象中,平均血红蛋白(114.7±17.0)g/L,贫血患病率为63.3%,以轻中度贫血为主,20～30岁组、31～40岁组和41～49岁组的贫血患病率分别为63.5%、63.2%和63.4%,差异无显著性。饮茶者的平均血红蛋白水平高于非饮茶者(t=3.33,P=0.001);饮茶与贫血患病存在统计学关联,饮茶者贫血的校正OR=0.56(95%CI:0.45,0.70),进一步的分析中,饮茶对无论轻度、中度还是重度贫血均有不同程度的保护效应,其校正OR分别为0.57(95%CI:0.43,0.75)、0.57(95%CI:0.43,0.75)和0.28(95%CI:0.11,0.70)。结论转型期的浙江德清农村社区已婚育龄女性的贫血患病率依然较高,饮茶可能与其贫血有一定的关系。

Relationship between tea-drinking and anaemia of rural reproductive married women in a community-based cross-sectional study in China

Objective to determine the prevalence of anaemia and the relationship between tea-drinking and anaemia in reproductive married women in rural China. Method A cross-sectional study was carried out in four rural communities in Deqing County, Zhejiang Province, China. A total of 1425 reproductive married women at the ages of 20 to 49 years participated in this study and had a satisfactory measure of hemoglobin. Their general information, health status and lifestyle behaviors were collected. Hemoglobin was tested by Drabkin Method. Chi-square test, and binary and multinomial Logistic regression models were used for statistical analysis in SPSS 11.0. Result Among 1425 subjects, the average concentration of hemoglobin were 114.7 ± 17.0g/L, the prevalences of anaemia were 63.3% , and most were mild and moderate anaemia (Such prevalence were 63.5% , 63.2% and 63.4% respectively at the ages of 20 - 30 years, 31 -40years, and 41 - 49 years.) . Subjects with tea-drinking were higher in average concentration of hemoglobin than those of no tea-drinking (t = 3.33, P = 0.001) . There were significant associations between tea-drinking and anaemia OR was 0.56 (95% C/:0.45,0.73) . Further, such protective effects of tea-drinking were observed among subjects with different anaemia [ORs were 0.57 (95%C/: 0.43,0.75), 0.57 (95% 67: 0.43,0.75), and 0.28 (95%67: 0.11,0.70)] in mild, moderate and severe anaemia, respectively. Conclusion The prevalence of anaemia in reproductive married women in rural of China could be higher and tea-drinking could be a possible protective factor.
