RESUMO

Objective: to investigate the association between different domains of physical activity and schooling among adult subjects. Methods: the present study had a crosssectional design. We carried out a household study of a sample of 890 adults aged 18 years or older living in the Ermelino Matarazzo district in the Eastern area of the city of Sao Paulo, Brazil. Physical activity during leisure and for locomotion/transportation was measured using the International Physical Activity Questionnaire (IPAQ), long version, and heavy cleaning at home and work-related physical activity were measured using sections of the System for Surveillance of Risk Factors and Protection against Chronic Diseases by Telephone Survey [Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico] (VIGITEL). Schooling was classified according to highest degree obtained, and later converted into years of study. Statistical analysis: we used Poisson regression to determine the association between physical activity in its different domains and schooling. Separate models were created for men and women. Dependent variables were as follows: active in leisure (150 min/week of moderate or vigorous physical activity), active for locomotion/transportation (150 min/week of walking or bicycling), active at work (working at least five days/week, substantial walking and/or load carrying during work), and active at home (unaided heavy home cleaning, at least one day in the previous week). The independent variable was schooling, in years of study (0-3, 4-7, 8-11, and 12 or more years), and age was used as an adjustment variable. Results: men were more active than women in leisure, locomotion/transportation, and work; however, women were more active at home. For physical activity during leisure, both men (PR=3.04 95 per centCI 1.00;9.31 and plinear trend=0.003 for the 12 years or more category), and women (PR=4.04 95 per centCI 1.33;12.20 and p-linear trend=0.006) with greater schooling showed a trend towards being more active during leisure. Regarding physical activity for purposes of locomotion/transportation, men with greater schooling (12 years or more) were protected against this type of activity (PR=0.26 95 per centCI 0.11;0.61 p-linear trend=0.002). As to heavy housecleaning, women with greater schooling were protected against this type of physical activity (PR=0.65 95 per centCI 0.43;1.00 p-linear trend=0.017 for the 12 years or more category). Conclusions: schooling was significantly and positively associated with physical activity during leisure among both sexes; however, it was inversely associated with physical activity as a form of locomotion/transportation among men and with heavy housecleaning among women. These results indicate that persons with greater schooling are more active in leisure and less active during locomotion/transportation and heavy housecleaning, and are important for a better understanding of these relationships in populations living in regions considered as of low socioeconomic level, such as Ermelino Matarazzo.
