First choice for use of health services by the adult population of the Federal District, Brazil, 2015: a cross-sectional study.

OBJECTIVE
to describe the first choice for use of health services and to analyze sociodemographic factors associated with seeking Primary Health Care (PHC) by the adult population of Brazil's Federal District in 2015.


METHODS
this was a population-based study, with 2,007 individuals, using a sample from the 2015 VIGITEL survey conducted by landline telephone, including questions on use of health services; we used logistic regression to identify factors associated with seeking PHC services.


RESULTS
participants' first choice was predominantly for private health services (57.6%), respondents reported seeking public health services less (39.5%), particularly PHC services (primary health centers: 24.6%); multivariate analysis showed that educational level (postgraduate [OR=0.15 - 95% CI 0.04;0.59] and high school [OR=0.37 - 95%CI 0.18;0.75]), and not having private health insurance (OR=27.77 - 95%CI 10.61;72.70) were variables associated with seeking PHC services.


CONCLUSION
individuals with low educational level and without private health insurance are those who mostly seek PHC services as their first choice in Brazil's Federal District.
