Comparison of nutritional status between adults with and without disabilities: a population-based cross-sectional...

There has been a notable lack of effort to evaluate the nutritional status of persons with disabilities objectively and identify their nutritional challenges. This study aimed to assess whether nutritional inadequacies and imbalances are more pronounced in persons with disabilities compared to those without, using data from the 6th Korea National Health and Nutrition Examination Survey (2013).

The participants were classified into 387 persons with disabilities and 4,909 without disabilities. The 15 types of disabilities were categorized into 5 groups, and disability severity was classified as severe or mild. Nutrient intake and nutritional status were assessed using 24-h dietary recall data.

Compared to persons without disabilities, those with disabilities had significantly lower nutrient adequacy ratios for 8 of 10 nutrients, the exceptions being vitamins B1 and C (all P < 0.05). The likelihood of low overall nutrient adequacy based on the mean adequacy ratio was significantly higher among persons with disabilities (odds ratio [OR], 1.50; 95% confidence interval [CI], 1.11-2.04), with particularly elevated odds for those with severe, visual, and internal organ disabilities. Persons with severe disabilities had higher odds of consuming a diet with low nutrient density (OR, 1.59; 95% CI, 1.05-2.40) and of experiencing nutritional deficiency (OR, 2.21; 95% CI, 1.02-4.75) than those without disabilities. Additionally, the odds of consuming a high-carbohydrate diet, with > 70% of daily energy intake from carbohydrates, was 3.63-fold higher (95% CI, 1.40-9.42) among persons with mental disabilities.

Persons with disabilities faced significant nutritional inadequacies and imbalances compared to those without disabilities. Targeted nutrition interventions and disability-inclusive nutrition policies and practices are urgently needed to reduce these disparities.
