【摘要】 [目的]评价铁强化酱油对儿童少年贫血改善效果。[方法]按随机对照双盲法在幼儿园、小学、中学6 000名中选择3～18岁儿童少年,分干预组1 263例和对照组1 236例分别食用铁强化酱油和对照普通酱油,追踪观测6个月后,检测血红蛋白变化水平和贫血患病率。[结果]服用铁强化酱油6个月后,干预组男、女儿童少年的血红蛋白浓度升高明显,与食用前及对照组相比差异有统计学意义(P﹤0.05～0.001);干预组男、女儿童少年的贫血患病率明显降低,平均降低68.75%,与食用前相比差异有统计学意义(P﹤0.001),贫血儿童中改善率达到86.17%;铁强化酱油知晓率90.36%,可接受程度87.95%。[结论]铁强化酱油可明显改善和降低儿童少年贫血患病率,是一种有效预防控制儿童少年贫血的营养干预措施。更多还原

【Abstract】 [Objective]To evaluate the improvement effects of iron fortified soy sauce on children and adolescents with iron deficiency anemia(IAD).[Methods]By using randomized controlled double blind method,a total of 2 472 students aged from 3 to 18 were selected from 6 000 students in kindergarten,primary and middle schools,and were equally divided into intervention group treated with iron fortified soy sauce and control group treated with ordinary soy sauce.After longitudinal observation for 6 months,the changes of hemoglobin and the prevalence rate of anemia were examined.[Results]After taking iron fortified soy sauce for 6 months,the hemoglobin levels of boys and girls in intervention group increased obviously,which were significantly higher compared with pre-treatment and the control group(P﹤0.05~0.001).And the prevalence rates of anemia among boys and girls in intervention group medially decreased by 68.75%,which were markedly lower than pre-treatment(P﹤0.001).86.17% children with anemia got to be improved,the awareness rate of iron fortified soy sauce was 90.36%,and the receptivity achieved 87.95%.[Conclusions]The iron fortified soy sauce can obviously improve and reduce the prevalence rate of anemia of children and adolescents,it is one kind of effective nutrition intervention measure for controlling anemia of children and adolescents.更多还原
