Background and Objective:
Healthcare for the elderly represents a challenge for Health Services (HS) at global, national and regional levels. It is known that Physical Activity (PA) during leisure decreases the frequency of HS utilization, leading to a decrease in expenses and being able to help control utilization in public emergency situations. However, the influence that each PA domain can provide is still uncertain. Thus, the purpose of this study was to analyze how the different domains of PA and PA-Total are related to the HS utilization.

Methods:
Cross-sectional data from 1019 participants of the Health Survey of the City of São Paulo-Brazil (ISA-Capital), aged 60 years or older (59.7% female; mean age 69.7 ± 7.7 years), were used. Respondents were classified in each domain of PA and PA-Total (IPAQ-long) and HS utilization (preventively, emergency and hospitalization). For the relationship between the PA domains and time of use of the HS, Spearman's correlation was used. Then, controlling for sociodemographic characteristics, lifestyle habits, quality of life and chronic diseases, using weightings for probalistic and complex samples, Poisson regression analysis.

Results:
There was a positive correlation between HS-preventive with PA-Total (r=0.098; p<0.01) and HS-emergency with PA-Transportation (r=0.158; p<0.01). Thus, the more you practice PA (Total and Transportation) the frequency of HS utilization is decreased. When controlling the analysis, active in PA-total and PA-leisure have 48% (PR=1.48; 95%CI 1.03-2.13) and 35% (PR=1.35; 95%CI 1.06-1.72) of probability of reporting that they consulted preventive in 3 months or more than their inactive peers. Actives in PA-Total have a 50% (PR=0.50; 95%CI 0.29-0.86) probability of not reporting hospitalization in the last 12 months when compared to inactive.

Conclusions:
The importance of PA in Healthcare and the support for the implementation of public health policies aimed at increasing the level of PA in the population are highlighted.
