Overweight and obesity among children at risk of intellectual disability in 20 low and middle income countries

The prevalence of significant cognitive delay among 3- to 4-year-old children growing up in low- and middle-income countries: results from 126 nationally representative surveys undertaken in 73 countries

BACKGROUND

We sought to (1) update estimates of the prevalence of significant cognitive delay (SCD) among nationally representative samples of young children overall, and in upper-middle, lower-middle and low-income countries; (2) investigate whether variation in prevalence between countries was systematically associated with national wealth and other country characteristics; (3) investigate the stability of prevalence estimates over time; (4) examine the correlation between SCD and 2019 Global Burden of Disease estimates on the prevalence of the impairment of developmental intellectual disability under 5 years of age; and (5) investigate the extent to which risk of SCD within countries varies with child age and gender, maternal education and household wealth.

METHODS

Secondary analysis of data collected in 126 nationally representative Multiple Cluster Indicators Surveys (MICS) conducted under the supervision of UNICEF in 73 countries involving a total of 396 596 3- to 4-year-old children.

RESULTS

The overall prevalence of SCD was 9.7% (95% CI 8.6-10.9%). Between-country variation in prevalence was strongly related to national wealth, the Human Development Index, the Human Inequality-adjusted Development Index and the Multidimensional Poverty Index, but not income inequality. In the 46 countries in which more than one survey was available prevalence estimates were reasonably stable over time (r = 0.80, P < 0.001). There were strong independent associations between increased risk of cognitive delay and younger child age, lower levels of maternal education and lower levels of household wealth (but not male gender). There was only a weak association across countries between the estimated prevalence of SCD and Global Burden of Disease estimates of the under 5 prevalence of the impairment of developmental intellectual disability.

CONCLUSIONS

UNICEF's MICS data are readily (and freely) available to researchers and provide a cost-effective opportunity for researchers who are concerned about better understanding the situation of young children growing up in the world's LMICs with a marked loss of developmental potential in areas of cognition and learning.

Understanding the contribution of intellectual disability nurses. Paper 2 of 4 - Survey

The objective was to identify ID nursing interventions and their impact on the health and healthcare of people with IDs. Data was collected using an online survey questionnaire from a voluntary response and snowball sample of 230 participants. Thematic, descriptive statistical, and inferential statistical analyses were undertaken. We identified 878 interventions that could be undertaken by ID nurses from 7 countries. We categorised the interventions into five themes: effectuating nursing procedures, enhancing impact of ID services, enhancing impact of mainstream services, enhancing quality of life, and enhancing ID nursing practice. Findings demonstrate that ID nurses play important roles in improving the health and healthcare experiences of people with IDs.

Prevalence and factors associated with overweight and obesity among Spanish students attending special education schools

BACKGROUND

Some studies suggest that children and adolescents with intellectual disability (ID) are at elevated risk of obesity. The objective was to determine the prevalence of and factors associated with overweight and obesity among students attending special education schools in Cantabria, Spain.

METHODS

Cross-sectional design. A sample of n = 220 students with intellectual disability attending seven special education schools was selected using convenience sampling. Body mass index was classified into four categories according to the International Obesity Task Force (IOTF) criteria: underweight; normal weight; overweight; obesity.

RESULTS

The prevalence of overweight/obesity was 40.9% (95% CI: 34.6-47.5). Obesity was more frequent among females (26.0%) than males (9.8%), with an OR = 3.23 (95% CI: 1.53-6.85). Participants with Down syndrome showed an increased risk of obesity compared to other conditions (p = .005).

CONCLUSIONS

The prevalence of overweight/obesity among children, adolescents and young adults with intellectual disability was remarkably high, with females in general and students of both sexes with Down syndrome at particularly high risk.

Obesity in youth and adults with intellectual disability in Europe and Eurasia

BACKGROUND

Information about obesity among people with intellectual disability comes mostly from small-scale, national samples in high-income countries. There are limited data from transnational studies.

METHOD

BMI scores had been obtained for over 25,000 youth and adults with intellectual disabilities drawn from 60 European and Eurasian countries. Their height and weight had been measured using standardized procedures when they attended Special Olympics Healthy Athletes events.

RESULTS

Binary logistic regression identified higher levels of obesity for athletes living in high-income countries, and for adult females, for those aged 30 years and over, and also for youth aged 8-13 years.

CONCLUSIONS

Participation in sports does not appear to have protected these athletes from obesity. Arguably, this remains the most pressing health issue for people with intellectual disability, particularly in Western Europe.

Securing rights and nutritional health for persons with intellectual disabilities - a pressing challenge

Persons with intellectual disabilities (ID) are dependent on nutritional policies that have so far not been addressed in a systematic and health-promoting manner in Norway and other nations with a high socioeconomic standard. In many poor countries, such issues have not even been raised nor addressed. Nutritional issues facing persons with ID include the risk of both underweight and overweight. Deficiency in energy, vitamins, essential fatty acids and micronutrients can increase the risk of additional health burdens in already highly vulnerable individuals. According to the World Health Organization, the obesity rates have tripled worldwide the last decades, and recent studies suggest that the prevalence of obesity is even higher for persons with ID than in the general population. This implies additional burdens of life style diseases such as diabetes and hypertension for adults with ID. According to the Diagnostic and Statistical Manual of Mental Disorders (DSM)-5, this group is characterized by intellectual difficulties as well as difficulties in conceptual, social, and practical areas of living. Their reduced intellectual capacity implies that they often have difficulties in making good dietary choices. As a group, they are dependent upon help and guidance to promote a healthy life style. To improve their health, there is a need for improved national services and for more research on lifestyle and nutritional issues in persons with ID. From a human rights perspective, these issues must be put on the agenda both in relevant UN fora and in the respective nations' health policies.
