Abstract

OBJECTIVES

To assess the nutritional status and dietary practices of 4-24-month-old children (under-twos) in a rural South African community.

DESIGN

Cross-sectional survey.

SETTING

A low socioeconomic rural African community (Ndunakazi), approximately 60 km north-west of Durban, KwaZulu-Natal, South Africa.

SUBJECTS

Children (n = 115), 4-24 months old who attended growth monitoring posts in the area.

RESULTS

Of these under-twos, 37.3% had low vitamin A status (serum retinol < 20 microg dl(-1)), 65.2% were anaemic, 43.2% had serum ferritin levels < 10 microg l(-1) (an indicator of low iron stores) and 15.3% were stunted. Breastfeeding was initiated by 99% of mothers. At the time of the survey, 80% of infants in the 4-12-month-old category and 56.9% of children in the 12-24-month-old category were being breastfed. Solid foods were introduced at 3.6 +/- 0.8 months. Food intake reflected a high intake of carbohydrate-rich foods, and irregular intakes of fruit and vegetables, especially those rich in vitamin A. Foods of animal origin were not consumed regularly. Of these under-twos, 15.9% experienced an episode of diarrhoea during 2 weeks prior to the survey.

CONCLUSION

These under-twos had a poor vitamin A and iron status. Nutrition education, intervention programmes and feeding schemes should address micronutrient deficiencies, with the focus on the quality of the diet, rather than quantity.

摘要

目的

评估南非农村社区4至24个月大儿童(两岁以下儿童)的营养状况和饮食习惯。

设计

横断面调查。

地点

南非夸祖鲁 - 纳塔尔省德班西北约60公里处的一个社会经济地位较低的农村非洲社区(恩杜纳卡齐)。

研究对象

该地区在生长监测点接受检查的4至24个月大儿童(n = 115)。

结果

在这些两岁以下儿童中,37.3%的儿童维生素A水平较低(血清视黄醇<20微克/分升),65.2%的儿童贫血,43.2%的儿童血清铁蛋白水平<10微克/升(铁储备低的指标),15.3%的儿童发育迟缓。99%的母亲开始进行母乳喂养。在调查时,4至12个月大的婴儿中有80%以及12至24个月大的儿童中有56.9%仍在接受母乳喂养。固体食物在3.6±0.8个月时开始添加。食物摄入量反映出富含碳水化合物的食物摄入量较高,而水果和蔬菜,尤其是富含维生素A的水果和蔬菜摄入量不规律。动物性食物摄入不规律。在这些两岁以下儿童中,15.9%在调查前2周内出现过腹泻。

结论

这些两岁以下儿童的维生素A和铁状况较差。营养教育、干预计划和喂养方案应解决微量营养素缺乏问题,重点是饮食质量而非数量。
