Inequalities in early childhood development (ECD) tend to persist into adulthood and amplify across the life course. To date, little research on inequalities in early childhood care and development in low/middle-income countries has been available to guide governments, donors and civil society in identifying which young children and families should be targeted by policies and programmes to improve nurturing care that could prevent them from being left behind.
Using data from 135 Demographic and Health Surveys and Multiple Indicator Cluster Surveys between 2010 and 2018, we assessed levels and trends of inequalities in exposure to risks of stunting or extreme poverty (under age 5; levels in 85 and trends in 40 countries), early attendance of early care and education programmes (36-59 months; 65 and 17 countries), home stimulation (36-59 months; 62 and 14 countries) and child development according to the Early Childhood Development Index (36-59 months; 60 and 13 countries). Inequalities within countries were measured as the absolute gap in three domains-child gender, household wealth and residential area-and compared across regions and country income groups.
63% of children were not exposed to stunting or extreme poverty; 39% of 3-4-year olds attended early care and education; and 69% received a level of reported home stimulation defined as adequate. Sub-Saharan Africa had the lowest proportion of children not exposed to stunting or extreme poverty (45%), attending early care and education (24%) and receiving adequate home stimulation (47%). Substantial gaps in all indicators were found across country income groups, residential areas and household wealth categories. There were no significant reductions in gaps over time for a subset of countries with available data in two survey rounds.
Available data indicate large inequalities in early experiences and outcomes. Efforts of reducing these inequalities must focus on the poorest families and those living in rural areas in the poorest countries. Improving and applying population-level measurements on ECD in more countries over time are important for ensuring equal opportunities for young children globally.
儿童早期发展(ECD)方面的不平等现象往往会持续到成年期,并在整个生命周期中扩大。迄今为止,关于低收入和中等收入国家儿童早期保育和发展方面不平等现象的研究很少,无法为政府、捐助者和民间社会提供指导,以确定哪些幼儿和家庭应成为政策和方案的目标,以便改善养育护理,防止这些幼儿落后。
利用 2010 年至 2018 年期间来自 135 次人口与健康调查和多个指标群集调查的数据,我们评估了面临发育迟缓或赤贫(五岁以下儿童)风险、早期参加早期保育和教育方案(36-59 个月儿童;65 个国家和 17 个趋势)、家庭刺激(36-59 个月儿童;62 个国家和 14 个趋势)以及根据幼儿发展指数(36-59 个月儿童;60 个国家和 13 个趋势)评估儿童发展的程度方面的不平等状况。各国内部的不平等状况是按照三个领域(儿童性别、家庭财富和居住地区)的绝对差距来衡量的,并与区域和国家收入组别进行了比较。
63%的儿童未面临发育迟缓或赤贫风险;39%的 3-4 岁儿童参加了早期保育和教育;69%接受了报告称充分的家庭刺激。撒哈拉以南非洲地区未面临发育迟缓或赤贫风险(45%)、未参加早期保育和教育(24%)以及未接受充分家庭刺激(47%)的儿童比例最低。在国家收入组别、居住地区和家庭财富类别方面,所有指标都存在巨大差距。在有两轮调查数据的部分国家中,没有发现这些差距随着时间的推移而显著缩小。
现有数据表明,幼儿的早期经历和结果存在很大差异。减少这些不平等现象的努力必须集中在最贫穷的家庭和最贫穷国家的农村地区。随着时间的推移,在更多国家提高和应用幼儿期发展方面的人口水平衡量标准,对于确保全球幼儿享有平等机会非常重要。
