Accelerating progress on early childhood development for children under 5 years with disabilities by 2030

The likelihood of a newborn child dying before their fifth birthday (under-5 mortality rate) is universally acknowledged as a reflection of the social, economic, health, and environmental conditions in which children (and the rest of society) live, but little is known about the likelihood of a newborn child having a lifelong disability before their fifth birthday if he or she survives. Available data show that globally the likelihood of a child having a disability before their fifth birthday was ten times higher than the likelihood of dying (377·2 vs 38·2 per 1000 livebirths) in 2019. However, disability funding declined by 11·4% between 2007 and 2016, and only 2% of the estimated US$79·1 billion invested in early childhood development during this period was spent on disabilities. This funding pattern has not improved since 2016. This paper highlights the urgent need to prioritise early childhood development for the beneficiaries of global child survival initiatives who have lifelong disabilities, especially in low-income and middle-income countries, as envisioned by the Sustainable Development Goals agenda. This endeavour would entail disability-focused programming and monitoring approaches, economic analysis of interventions services, and substantial funding to redress the present inequalities among this cohort of children by 2030.

Global Burden of Childhood Epilepsy, Intellectual Disability, and Sensory Impairments

BACKGROUND

Estimates of children and adolescents with disabilities worldwide are needed to inform global intervention under the disability-inclusive provisions of the Sustainable Development Goals. We sought to update the most widely reported estimate of 93 million children <15 years with disabilities from the Global Burden of Disease Study 2004.

METHODS

We analyzed Global Burden of Disease Study 2017 data on the prevalence of childhood epilepsy, intellectual disability, and vision or hearing loss and on years lived with disability (YLD) derived from systematic reviews, health surveys, hospital and claims databases, cohort studies, and disease-specific registries. Point estimates of the prevalence and YLD and the 95% uncertainty intervals (UIs) around the estimates were assessed.

RESULTS

Globally, 291.2 million (11.2%) of the 2.6 billion children and adolescents (95% UI: 249.9-335.4 million) were estimated to have 1 of the 4 specified disabilities in 2017. The prevalence of these disabilities increased with age from 6.1% among children aged <1 year to 13.9% among adolescents aged 15 to 19 years. A total of 275.2 million (94.5%) lived in low- and middle-income countries, predominantly in South Asia and sub-Saharan Africa. The top 10 countries accounted for 62.3% of all children and adolescents with disabilities. These disabilities accounted for 28.9 million YLD or 19.9% of the overall 145.3 million (95% UI: 106.9-189.7) YLD from all causes among children and adolescents.

CONCLUSIONS

The number of children and adolescents with these 4 disabilities is far higher than the 2004 estimate, increases from infancy to adolescence, and accounts for a substantial proportion of all-cause YLD.

Intimate Partner Violence, Poverty, and Maternal Health Care-Seeking Among Young Women in Kenya: a Cross-Sectional Analysis Informing the New Sustainable Development Goals

BACKGROUND

Despite considerable achievements associated with the MDGs, under-five mortality, particularly in Sub-Saharan Africa, remains alarmingly high. Globally, intimate partner violence (IPV) affects one in three women within their lifetime. Little is known about the relationship between IPV and maternal care-seeking in the context of high rates of under-five mortality, particularly among young women and adolescent girls in low- and middle-income countries (LMICs).

METHODS

Data from the Kenya Demographic Health Survey (2008-2009) were limited to a sample of women aged 15-24 years (n=1,406) with a child under-five who had experienced IPV in the last 12 months. Using multivariate logistic regression, we constructed three models: 1) base model; 2) controlling for type of residence (urban/rural); and 3) controlling for wealth status and education attainment, to estimate odds ratios (ORs) for the association between IPV and ten maternal care-seeking behaviors.

RESULTS

Thirty-eight percent of the women had experienced some form of intimate partner violence in the last 12 months. Women who had experience IPV were less likely: 1) to complete a minimum of 4 antenatal visits after single IPV exposure (OR=0.61, 95% CI=0.44, 0.86 and after severe IPV (OR=0.80; 95% CI=0.44, 0.88) and 2) to deliver in health facility after severe IPV exposure (OR=0.74; 95% CI=0.54, 0.89), both adjusted for educational attainment and wealth status. Lower socio-economic status and living in a rural area were strongly associated with increased likelihood of IPV.

CONCLUSIONS

Intersectional approaches that consciously focus on, and creatively address IPV may be key to the success of reducing child mortality and improving maternal health outcomes. The implementation of joint programming and development of combination interventions to effectively reduce the risk of exposure to IPV and promote maternal care-seeking behavior are needed to improve child morbidity and mortality in LMICs.

Developmental disabilities among children younger than 5 years in 195 countries and territories, 1990-2016: a systematic analysis for the Global Burden of Disease Study 2016

BACKGROUND

The Sustainable Development Goals (SDGs) mandate systematic monitoring of the health and wellbeing of all children to achieve optimal early childhood development. However, global epidemiological data on children with developmental disabilities are scarce. The Global Burden of Diseases, Injuries, and Risk Factors Study 2016 provides a comprehensive assessment of prevalence and years lived with disability (YLDs) for development disabilities among children younger than 5 years in 195 countries and territories from 1990 to 2016.

METHODS

We estimated prevalence and YLDs for epilepsy, intellectual disability, hearing loss, vision loss, autism spectrum disorder, and attention deficit hyperactivity disorder. YLDs were estimated as the product of the prevalence estimate and the disability weight for each mutually exclusive disorder, corrected for comorbidity. We used DisMod-MR 2.1, a Bayesian meta-regression tool, on a pool of primary data derived from systematic reviews of the literature, health surveys, hospital and claims databases, cohort studies, and disease-specific registries.

FINDINGS

Globally, 52·9 million (95% uncertainty interval [UI] 48·7-57·3; or 8·4% [7·7-9·1]) children younger than 5 years (54% males) had developmental disabilities in 2016 compared with 53·0 million (49·0-57·1; or 8·9% [8·2-9·5]) in 1990. About 95% of these children lived in low-income and middle-income countries. YLDs among these children increased from 3·8 million (95% UI 2·8-4·9) in 1990 to 3·9 million (2·9-5·2) in 2016. These disabilities accounted for 13·3% of the 29·3 million YLDs for all health conditions among children younger than 5 years in 2016. Vision loss was the most prevalent disability, followed by hearing loss, intellectual disability, and autism spectrum disorder. However, intellectual disability was the largest contributor to YLDs in both 1990 and 2016. Although the prevalence of developmental disabilities among children younger than 5 years decreased in all countries (except for North America) between 1990 and 2016, the number of children with developmental disabilities increased significantly in sub-Saharan Africa (71·3%) and in North Africa and the Middle East (7·6%). South Asia had the highest prevalence of children with developmental disabilities in 2016 and North America had the lowest.

INTERPRETATION

The global burden of developmental disabilities has not significantly improved since 1990, suggesting inadequate global attention on the developmental potential of children who survived childhood as a result of child survival programmes, particularly in sub-Saharan Africa and south Asia. The SDGs provide a framework for policy and action to address the needs of children with or at risk of developmental disabilities, particularly in resource-poor countries.

Global burden of diseases, injuries, and risk factors for young people's health during 1990-2013: a systematic analysis for the Global Burden of Disease Study 2013

BACKGROUND

Young people's health has emerged as a neglected yet pressing issue in global development. Changing patterns of young people's health have the potential to undermine future population health as well as global economic development unless timely and effective strategies are put into place. We report the past, present, and anticipated burden of disease in young people aged 10-24 years from 1990 to 2013 using data on mortality, disability, injuries, and health risk factors.

METHODS

The Global Burden of Disease Study 2013 (GBD 2013) includes annual assessments for 188 countries from 1990 to 2013, covering 306 diseases and injuries, 1233 sequelae, and 79 risk factors. We used the comparative risk assessment approach to assess how much of the burden of disease reported in a given year can be attributed to past exposure to a risk. We estimated attributable burden by comparing observed health outcomes with those that would have been observed if an alternative or counterfactual level of exposure had occurred in the past. We applied the same method to previous years to allow comparisons from 1990 to 2013. We cross-tabulated the quantiles of disability-adjusted life-years (DALYs) by quintiles of DALYs annual increase from 1990 to 2013 to show rates of DALYs increase by burden. We used the GBD 2013 hierarchy of causes that organises 306 diseases and injuries into four levels of classification. Level one distinguishes three broad categories: first, communicable, maternal, neonatal, and nutritional disorders; second, non-communicable diseases; and third, injuries. Level two has 21 mutually exclusive and collectively exhaustive categories, level three has 163 categories, and level four has 254 categories.

FINDINGS

The leading causes of death in 2013 for young people aged 10-14 years were HIV/AIDS, road injuries, and drowning (25·2%), whereas transport injuries were the leading cause of death for ages 15-19 years (14·2%) and 20-24 years (15·6%). Maternal disorders were the highest cause of death for young women aged 20-24 years (17·1%) and the fourth highest for girls aged 15-19 years (11·5%) in 2013. Unsafe sex as a risk factor for DALYs increased from the 13th rank to the second for both sexes aged 15-19 years from 1990 to 2013. Alcohol misuse was the highest risk factor for DALYs (7·0% overall, 10·5% for males, and 2·7% for females) for young people aged 20-24 years, whereas drug use accounted for 2·7% (3·3% for males and 2·0% for females). The contribution of risk factors varied between and within countries. For example, for ages 20-24 years, drug use was highest in Qatar and accounted for 4·9% of DALYs, followed by 4·8% in the United Arab Emirates, whereas alcohol use was highest in Russia and accounted for 21·4%, followed by 21·0% in Belarus. Alcohol accounted for 9·0% (ranging from 4·2% in Hong Kong to 11·3% in Shandong) in China and 11·6% (ranging from 10·1% in Aguascalientes to 14·9% in Chihuahua) of DALYs in Mexico for young people aged 20-24 years. Alcohol and drug use in those aged 10-24 years had an annual rate of change of >1·0% from 1990 to 2013 and accounted for more than 3·1% of DALYs.

INTERPRETATION

Our findings call for increased efforts to improve health and reduce the burden of disease and risks for diseases in later life in young people. Moreover, because of the large variations between countries in risks and burden, a global approach to improve health during this important period of life will fail unless the particularities of each country are taken into account. Finally, our results call for a strategy to overcome the financial and technical barriers to adequately capture young people's health risk factors and their determinants in health information systems.
