Women in sub-Saharan Africa play a key role in household food security. The income-generating activities of mothers are postulated to be related to the nutritional status of children.
The objective of the study was to examine whether maternal income-generating activities, maternal food production, and child care were determinants of the nutritional status of children in rural West Africa. The study hypotheses were that maternal income-generating activities and maternal food production are positively associated with children's dietary intake and anthropometry, and that maternal income-generating activities are not associated with child care.
Data were collected from a cross-sectional sample of mother-child pairs on maternal time use, child anthropometry, maternal food production, dietary intake, parasitic infection, and household, maternal, and child determinants of child nutritional status. The children were 12 to 36 months of age and included breastfed and nonbreastfed children. Food intake was assessed by the 24-hour recall method. The data were analyzed by multivariate regression and controlled for confounding variables.
Time spent by the mother in income-generating activities was negatively associated with children's animal protein intake and height-for-age (p < .05). Maternal cash crop production was positively associated with children's weight-for-height, whereas maternal staple food production was negatively associated with energy intake from non-breastmilk foods (p < .05). The negative relationships observed for children's animal protein intake and children's height-for-age were not mediated by any child-care variable. Maternal supervision of feeding was a positive predictor of children's animal protein intake. Giardia infection was negatively related to children's weight gain (p < .05).
Own-account cash crop farming by mothers benefits children's nutrition. Maternal income-generating activities in the context of extended families, sibling caretaking, and prolonged breastfeeding do not adversely affect child care.
撒哈拉以南非洲地区的女性在家庭粮食安全方面发挥着关键作用。据推测,母亲的创收活动与儿童的营养状况有关。
本研究的目的是检验母亲的创收活动、母亲的粮食生产和儿童照料是否是西非农村地区儿童营养状况的决定因素。研究假设为,母亲的创收活动和母亲的粮食生产与儿童的饮食摄入量和人体测量指标呈正相关,且母亲的创收活动与儿童照料无关。
从母婴对的横断面样本中收集数据,内容包括母亲的时间利用情况、儿童人体测量指标、母亲的粮食生产、饮食摄入量、寄生虫感染情况,以及影响儿童营养状况的家庭、母亲和儿童相关因素。儿童年龄在12至36个月之间,包括母乳喂养和非母乳喂养的儿童。通过24小时回忆法评估食物摄入量。对数据进行多元回归分析,并对混杂变量进行控制。
母亲用于创收活动的时间与儿童的动物蛋白摄入量和年龄别身高呈负相关(p < 0.05)。母亲的经济作物生产与儿童的身高别体重呈正相关,而母亲的主食生产与非母乳食品的能量摄入量呈负相关(p < 0.05)。在儿童动物蛋白摄入量和年龄别身高方面观察到的负相关关系未被任何儿童照料变量所介导。母亲对喂养的监督是儿童动物蛋白摄入量的一个积极预测因素。贾第虫感染与儿童体重增加呈负相关(p < 0.05)。
母亲自主经营经济作物种植对儿童营养有益。在大家庭环境、兄弟姐妹照料和长期母乳喂养背景下的母亲创收活动不会对儿童照料产生不利影响。
