Objectives . To determine the effect of consumption of a lipid-based nutrient supplement (LNS) on hemoglobin levels, anemia and anthropometric indicators in children aged six to eleven months old in five districts in the province of Ambo in the region of Huanuco, Peru.
A pre-experimental, pre-post study was performed. The study population included children aged six to eleven months old in 19 health facilities in five districts with very high vulnerability to chronic malnutrition in the province of Ambo, Huanuco. Data from 147 children who received the lipid-based nutrient supplement (LNS) from six to eleven months old were obtained.
The mean hemoglobin significantly increased by 0.67 g/dL (p<0.05), the proportion of anemia dropped by 27 percentage points (p<0.001) and the mean z score for height/age decreased by 0.12 (p<0.05). No significant differences for z scores of weight/age and weight/height at the end of the study were found. The LNS had an adherence greater than 90%, and less than 10% of children in the study reported discomfort during consumption.
LNS supplementation achieved improved hemoglobin levels and reduced the prevalence of anemia in children under twelve months, which might constitute an effective alternative to prevent and control childhood anemia.
目的。确定食用脂质营养补充剂(LNS)对秘鲁瓦努科地区安博省五个区6至11个月大儿童的血红蛋白水平、贫血情况和人体测量指标的影响。
进行了一项实验前、实验后的研究。研究人群包括瓦努科省安博省五个极易患慢性营养不良的区的19个卫生设施中6至11个月大的儿童。获取了147名6至11个月大接受脂质营养补充剂(LNS)的儿童的数据。
平均血红蛋白显著增加0.67 g/dL(p<0.05),贫血比例下降27个百分点(p<0.001),身高/年龄的平均z评分下降0.12(p<0.05)。研究结束时,年龄别体重和身高别体重的z评分未发现显著差异。LNS的依从性大于90%,研究中不到10%的儿童在食用期间报告有不适。
补充LNS可提高12个月以下儿童的血红蛋白水平并降低贫血患病率,这可能是预防和控制儿童贫血的有效替代方法。
