| 摘 要： | 采用铁剂与安慰剂组间相互对照的双盲干预试验研究方法,将80名19至44岁患有铁缺乏非妊娠期的女工随机分配于铁剂组或安慰剂组,跟踪10至12周,观察干预前后血生化指标,工作时间及业余时间总能量消耗,产量,生产效率的变化。 铁剂治疗后平均血红蛋白上升13g/L,血清铁蛋白上升20.3μg/L,红细胞游离原卟啉下降293μg/L,工作时间总能量消耗下降467kJ/d,生产效率增加0.32元/MJ。自身对照t检验及与安慰剂组比较的组间t检验均显示铁剂治疗前后以上各种变化显著。

| Abstract: | The double blind intervention trial was designed for this study. 80 non-pregnant, iron deficient women aged between 19 and 44 were randomly assigned to iron (60 or 120 mg elemental iron per day) or placebo treatment for 10 to 12 weeks. The changes in hematological parameters, total energy expenditure at work, production and production efficiency were observed.In iron-treated group, the mean hemoglobin increased on average by 13 g/L, serum ferritin increased by 20.3μg/L, free erythrocyte protoporphyrin decreased by 29.3μg/100ml, total energy expenditure at work decreased by 467kJ/d, production efficiency increased by 0.32 yuan/MJ. Both paired t-test and group t-test show that fore-mentioned changes are statistically significant. |
