Social inequalities in limitations caused by chronic diseases and disabilities in Brazil: the 2013 National Health Survey

The main exposure was the economy class, classified into five categories, ranging from A (richest) to E (poorest). We estimated a logistic regression model adjusted for economy class and confounding variables, considering the complex sample design and alpha = 5%. Around 15.5% of individuals reported having Limit.

Comparing social classes, 19.5%, 21.9%, 16.1%, 11.1%, and 7.7% individuals belonging to class E, D, C, B and A reported the outcome. The adjusted model showed greater odds of individuals in class D + E, and D, reporting LIMIT than individuals of class A + B (reference). Public policies for health care and social welfare for people with disabilities should focus on social classes E and D.
