【摘要】目的 了解农村中学生贫血现状,观察铁强化酱油对中学生缺铁性贫血改善的效果,为制定青少年缺铁性贫血防治策略和措施提供科学依据。方法 选择汶上县在学校食堂就餐的中学生1684名,采用双盲安慰剂对照法进行为期6个月的铁强化酱油干预试验。观察指标主要是血红蛋白。干预组828例,每天食用乙二胺四乙酸铁钠酱油烹饪的饭菜;对照组856例,食用普通酱油(无乙二胺四乙酸铁钠)。分别于研究开始、干预后3、6个月三次检测血红蛋白含量。采用SPSS13.0统计软件,对血红蛋白水平进行重复测量方差分析,Cochran-Armitage趋势检验分析贫血患病率的变化。结果 食用铁强化酱油3、6 个月后,干预组的血红蛋白水平明显升高(F=101.12,P<0.01),贫血患病率显著降低(Z=-4.6230,P<0.01);对照组血红蛋白值干预前后无明显差异(F=0.91,P =0.3876),贫血患病率有所降低,但无统计学意义(Z=-1.0329,P=0.3016)。结论 铁强化酱油改善缺铁性贫血效果显著。

【Abstract】Objective To learn the anemia situation of rural middle school students, and evaluate the effect of anemia prevention through dietary supplementing of iron-fortified soy sauce, then to provide scientific basis for developing the strategies and measures to prevent iron-deficiency anemia in elementary and middle school student. Methods 1684 students who have the meal in the school canteen of the county Wenshang were chosen. We conducted a 6-month randomized placebo-controlled intervention trial in the students, using NaFe-EDTA fortified soy sauce. The main parameter of this study is hemoglobin. The intervention group (828) ate the dietary supplementing of iron-fortified soy sauce and the control group (856) ate the dietary supplementing of ordinary soy sauce. Changes of index were measured separately in the beginning, 3-month and 6-month of test. Analysising the dates by Spss 13.0 to learn the changes of the level of the hemoglobin. Results The levels of hemoglobin significantly increased after 3-month and 6-month of this trial(F=101.12,P<0.01),and the prevalence of anemia was significantly lower(Z=-4.6230,P<0.01)compared with the control group;there was no significant difference in control group (F=0.91,P =0.3876), and prevalence of anemia was lower, but there was no statistical significance(Z = -1 ......
