The scope of this paper was to estimate the prevalence of multimorbidity in the city of S & atilde;o Paulo and to verify the factors associated with the utilization of the health services. It involved a population based cross-sectional study based on data from the Health Survey in the city of S & atilde;o Paulo, in which descriptive analysis was conducted, and logistic regression models were developed using multimorbidity and sociodemographic independent variables, living conditions and use of health services as the outcome. A total of 3,184 individuals aged 20 years or older participated, with a mean age of 43.8 years. The prevalence of multimorbidity was 50.7% among women, 62.5% among those who reported some health problem and 55.1% among those who had recourse to health services in the last 2 weeks. A higher prevalence was identified among those who used the health service due to a mental health problem (66.1%), and in those who reported higher health expenditures in the preceding month (55.4%). Multimorbidity was more frequently associated with aging, in the population with a higher economic status, with worse self-rated health, who frequented health services for 6 months or less, who reported a health problem, or who had a health plan and opted for polypharmacy.
