Abstract: Background: Adherence to recommendations for physical activity (PA) among adults in the United States is reported as poor, particularly among low-income Latinos. In particular, Latina women are at increased risk for inactivity and chronic illness, but national health survey reports aggregate data across demographic strata, limiting descriptive information that could guide targeted PA promotion. The purpose of the study was to determine PA patterns among a low-income group of Latina women in the southwestern United States. Methods: As part of a large community intervention trial to increase cancer prevention behaviors, PA data were collected from 1,006 Latina women using a modified version of the Arizona Activity Frequency Questionnaire. Findings: The weekly PA mean across all exercise types was calculated to be 9.3 ± 16.4 hours, which is substantially higher than the daily PA recommendation of 30 minutes most days of the week. The highest daily PA means were associated with occupational activities: Cleaning, 2.7 hours; walking, 2.5 hours; lifting, 1.9 hours; and light yard work, 1.0 hours. Conclusions: In this sample of low-income Latina women, the average PA hours per week exceed the current PA recommendations. Data collection instruments used in this population could more accurately assess PA if they included a wider range of activities and specific questions about work-related activity.
