Abstract
Background: Epidemiologic studies have shown that inadequate physical activity was associated with cancers in whites and other ethnic groups, but in Mexican-Americans data are limited. This study aimed to measure the association between physical activity and reported cancer risk in Mexican-Americans.
Methods: Participants were drawn from the Cameron County Hispanic Cohort (n=3,391), a randomly selected Mexican-American cohort in Texas on the US-Mexico border. Physical activity was assessed using the International Physical Activity Questionnaire. Cancer was self-reported by the participants as being told by a health care provider that they had cancer.
Results: Ninety-nine participants of the cohort (2.94%) reported a diagnosis of cancer. Compared to participants who did not meet US physical activity guidelines, subjects who met physical activity guidelines of 150 moderate and vigorous minutes per week (≥ 600 METs) reduced their risk for cancer by 87% (OR=0.13; 95% CI: 0.03-0.54), and subjects with total minutes per week of moderate and vigorous/strenuous activity greater than 745 METs decreased cancer risk by 86% [odds ratio (OR)=0.14; 95% confidence interval (CI): 0.03-0.60] comparing with their counterparts, after adjusting for age, gender, body mass index, smoking and alcohol drinking status, education and total portions of fruit and vegetable intake.
Conclusions: Meeting or exceeding recommended levels of moderate and vigorous physical activity was associated with a significantly reduced risk of reporting cancer by Mexican-Americans. Meeting or exceeding recommended levels of physical activity appears to be an effective target for cancer prevention and control among Mexican-Americans independent of BMI and other factors.
