This study purposed to examine the difference in the prevalence of obesity at each stage among people with and without disabilities considering the severity and type of disability.
The study targeted a total of 1,315,967 people, including 68,418 disabled and 1,247,549 non-disabled, who completed the national health screenings. Logistic analysis and average marginal effect analysis were conducted in three stages (pre-obesity, obesity, severe obesity). Those analyses were conducted considering the severity and type of disabilities.
People with disabilities were more likely to be at all stages of obesity than non-disabled people. In severely disabled people, the probability of obesity was higher than non-disabled people at all stages of obesity, but mildly disabled people had a higher only in the severe obesity stage, no difference in obesity stage, and a low in the pre-obesity stage. In physical and mental disabilities, the probability of obesity was higher than non-disabled people at all stages of obesity, but external physical function and internal organs disabled had a lower in the obesity and pre-obesity stage, and no difference in severe obesity stage.
This study found that people with disabilities had a higher relationship with obesity than people without disabilities. In addition, severity and types of disabilities have different effects on the stage of obesity. Therefore, it is necessary to care about the health inequality and health of disabled people considering their severity and types of disabilities.
