Neurodevelopmental disability (NDD) is increasingly acknowledged as one of the important causes of disease burden in low income countries. None the less, there is a dearth of data on the burden of NDD and its determinants in these settings. We aimed to establish the prevalence and factors associated with NDD among infants in Eastern Uganda.
We assessed 487 infants aged 9-12 months within Iganga-Mayuge Health Demographic Surveillance Site in Eastern Uganda using the Malawi Developmental Assessment Tool. The tool has four domains: gross motor, fine motor, language and social domains. An infant failed a domain if she/he failed more than two parameters of the expected at his/her age. We interviewed mothers on factors that could influence the infants' neurodevelopmental outcomes. Data were analysed using STATA version 14. We used odds ratios and 95% confidence intervals to assess statistical significance of associations.
Of the 487 infants, 62(12.7%) had an NDD in at least one of the domains. The most affected was social behaviour where 52(10.7%) infants had an NDD. Severe impairment was seen among 9(1.8%) infants with NDD in either three or four domains. Factors associated with NDD at multivariate logistic regression included: parity of more than three children (aOR = 1.8, 95% CI: 1.02-3.18); failure to cry at birth (aOR = 3.6, 95% CI: 1.46-9.17) and post-neonatal complications (aOR = 4.15, 95% CI: 1.22-14.10). Low birth weight, immediate and exclusive breast feeding were not significantly associated with NDD.
We found a high NDD burden among infants particularly in the social behaviour domain. To optimise the socio-neural development of infants, programs are needed to educate and work with families on how to engage and stimulate infants. Existing immunisation clinics and community health worker strategies provide an excellent opportunity for stemming this burden.
神经发育障碍(NDD)日益被认为是低收入国家疾病负担的重要原因之一。然而,这些国家关于 NDD 负担及其决定因素的数据却很少。我们旨在确定乌干达东部婴儿 NDD 的患病率和相关因素。
我们在乌干达东部的伊甘加-马尤盖卫生人口监测点评估了 487 名 9-12 个月大的婴儿,使用马拉维发育评估工具进行评估。该工具包含四个领域:粗大运动、精细运动、语言和社交领域。如果婴儿在其年龄的预期中未能通过两个以上参数,则该婴儿在该领域失败。我们采访了母亲,了解可能影响婴儿神经发育结果的因素。数据使用 STATA 版本 14 进行分析。我们使用比值比和 95%置信区间来评估关联的统计学意义。
在 487 名婴儿中,有 62 名(12.7%)在至少一个领域存在 NDD。受影响最严重的是社交行为,其中 52 名(10.7%)婴儿存在 NDD。有 9 名(1.8%)婴儿在三个或四个领域均存在严重障碍。多变量逻辑回归分析显示,与 NDD 相关的因素包括:多胎(产次大于 3 次)(aOR=1.8,95%CI:1.02-3.18);出生时不哭(aOR=3.6,95%CI:1.46-9.17)和新生儿后期并发症(aOR=4.15,95%CI:1.22-14.10)。低出生体重、立即和纯母乳喂养与 NDD 无显著相关性。
我们发现婴儿的 NDD 负担很高,特别是在社交行为领域。为了优化婴儿的社会神经发育,需要开展相关项目,教育和指导家庭如何与婴儿互动和刺激婴儿。现有的免疫接种诊所和社区卫生工作者策略为减轻这一负担提供了极好的机会。
