茶是一些地区和民族婴儿饮食中普遍使用的饮料,为了评价饮茶对婴儿小细胞性贫血发生的影响,我们调查了122名年龄在6～12月内接受常规血液检验的健康婴儿,发现贫血(Hb<11g/dl-48.4％),小红细胞症(MCV<70μm~3-21.3％)及小细胞性贫血(19％)的发病率均较高。饮茶婴儿患小细胞性贫血的百分率(32.6％)明显高于不饮茶婴儿(3.5％),每日饮茶量50～750m1(中位数250ml),饮茶者血红蛋白平均水平显著低于不饮茶者(10.5±1.2g/dl与11.2±0.8g/dl.P<0.02),红细胞平均容积的平均水平也显著低于不饮
Tea is a popular drink for some regions and ethnic infants. In order to evaluate the effect of tea drinking on infantile small cell anemia, we investigated 122 healthy infants undergoing routine blood tests from June to December and found anemia (Hb <11g / dl-48.4%), the incidence of microcytosis (MCV <70μm ~ 3-21.3%) and small cell anemia (19%) were higher. The percentage of infantile anemia in tea infants (32.6%) was significantly higher than that in non-infants (3.5%), with a daily drinking volume of 50-750 ml (median 250 ml). The average level of hemoglobin in tea drinkers was significantly lower The average level of mean red blood cell volume was also significantly lower in non-tea drinkers (10.5 ± 1.2 g / dl vs 11.2 ± 0.8 g / dl, P <0.02)
