Resumo
Objective
To examine the association between Body Mass Index (BMI) and self-rated health status among a representative sample of the Brazilian population.
Methods
This study consists of a secondary analysis of the existing 2019 Brazilian National Health Survey (PNS). Logistic regression models were then used to examine the association between self-reported health status and BMI, while controlling for obesity-related medical conditions and socio-demographic characteristics.
Results
The representative sample included 34,021 men and 34,430 women, comprising a total sample of 68,451. Men living with obesity (BMI ≥ 30 kg/m2) had, on average, a lower self-reported health status score (OR = 0.69, p < 0.01) compared to men within a healthy weight BMI range (18.5–25 kg/m2). Women living with obesity had, on average, a lower self-reported health status score (OR = 0.56, p < 0.01) compared to women within a healthy weight BMI range (18.5–25 kg/m2). There was also a statistically significant negative association (p < 0.01) between our obesity-related medical conditions and self-reported health for men and women. We also find some evidence of a non-linear association between BMI and health status for men.
