[Association between self-reported state of health among adults and the location of the home: ordinal logistic regression analysis using PNAD 2008].

The urban environment influences human health and behavior, and a clearer understanding of the health determinants of populations living in cities is needed. Using data from the National Household Sampling Survey (PNAD) 2008, with ordinal logistic models incorporating the sampling plan, this study assessed the association between the location of the home (urban or rural) and the self-reported state of health of the adult Brazilian population, taking into account a set of individual and environmental factors inside and outside the home. The results indicated that after allowing for individual and environmental factors, the association between the location of the home and the self-reported state of health is changing (going from OR = 1.51 to OR = 0.96) and losing its statistical significance (p-value = 0.208). However, statistically significant interactions were observed between the location of the home and the following variables: sex, color/race, self-reported morbidity, possession of basic goods and percentage of households with adequate living conditions.
