Despite improvements in childhood undernutrition through integrated nutritional programs in South Africa, stunting among children remains persistent, and is attributed to poor socio-demographic status. This context has been implicated in disrupting mothers' decisions regarding effective infant feeding, ultimately meaning that children's nutritional demands remain unmet. In view of this, we conducted a cross-sectional study to determine the association between socio-demographic factors and infant and young child feeding (IYCF) practices and stunting among children under two years receiving primary health care in informal settlements in Gauteng, South Africa. A validated questionnaire was used to assess mothers' socio-demographic status and feeding practices using WHO core indicators. Stunting was defined as length-for age z-scores (LAZ) below -2 standard deviation, computed using WHO Anthro software version 3.2.2.1 using age, sex, and anthropometric measurements of children. Univariate and multivariate analyses were stratified by stunting to determine the relationship with socio-demographic, infant, and IYCF factors using STATA 17. The prevalence of stunting was 16% among surveyed children under two years (with a mean age of 8 ± 5 months) living in poor socio-demographic households. Poor feeding practices were characterized by delayed initiation of breastfeeding (58%), sub-optimal exclusive breastfeeding (29%), discontinued breastfeeding (44%), early introduction of solid foods (41%), and low dietary diversity (97%). Significant differences in terms of child's age, monthly household income, and ever being breastfed were observed (Chi square test and univariate analysis). After controlling for potential confounders, stunting was significantly associated with child's age [12-23 months: AOR = 0.35, 95% CI: 0.16-0.76], and monthly household income [ZAR 3000-ZAR 5000: AOR = 0.47, 95% CI: 0.26-0.86]. Despite the few aforementioned socio-demographic and IYCF factors associated with stunting, this study reiterates stunting as the commonest poor nutritional status indicator among children under two years, suggesting the presence of chronic undernutrition in these poverty-stricken informal settlements. A multisectoral approach to address stunting should be context-specific and incorporate tailor-made interventions to promote optimal infant-feeding practices. Conducting future nutrient assessments focusing on children is imperative.
尽管南非通过综合营养项目在儿童期营养不良问题上取得了进展,但儿童发育迟缓现象仍然持续存在,这归因于社会人口统计学状况不佳。这种情况被认为干扰了母亲们关于有效婴儿喂养的决策,最终意味着儿童的营养需求仍未得到满足。鉴于此,我们开展了一项横断面研究,以确定在南非豪登省非正式定居点接受初级卫生保健的两岁以下儿童中,社会人口统计学因素与婴幼儿喂养(IYCF)做法及发育迟缓之间的关联。我们使用一份经过验证的问卷,通过世界卫生组织的核心指标来评估母亲的社会人口统计学状况和喂养做法。发育迟缓被定义为年龄别身长Z评分(LAZ)低于-2个标准差,使用世界卫生组织Anthro软件3.2.2.1版,根据儿童的年龄、性别和人体测量数据进行计算。我们使用STATA 17软件,按发育迟缓情况进行分层单因素和多因素分析,以确定与社会人口统计学、婴儿及婴幼儿喂养因素之间的关系。在生活在社会人口统计学状况较差家庭的两岁以下受调查儿童中(平均年龄为8±5个月),发育迟缓的患病率为16%。不良喂养做法的特点包括母乳喂养开始延迟(58%)、纯母乳喂养不充分(29%)、停止母乳喂养(44%)、过早引入固体食物(41%)以及饮食多样性低(97%)。在儿童年龄、家庭月收入以及是否曾经接受母乳喂养方面观察到了显著差异(卡方检验和单因素分析)。在控制了潜在混杂因素后,发育迟缓与儿童年龄[12 - 23个月:调整后比值比(AOR)= 0.35,95%置信区间(CI):0.16 - 0.76]以及家庭月收入[3000兰特 - 5000兰特:AOR = 0.47,95% CI:0.26 - 0.86]显著相关。尽管上述与发育迟缓相关的社会人口统计学和婴幼儿喂养因素较少,但本研究重申发育迟缓是两岁以下儿童中最常见的不良营养状况指标,这表明在这些贫困的非正式定居点存在慢性营养不良问题。应对发育迟缓的多部门方法应因地制宜,并纳入量身定制的干预措施,以促进最佳的婴儿喂养做法。开展未来针对儿童的营养评估势在必行。
