Meeting physical activity recommendations for colon cancer prevention among Japanese adults: prevalence and sociodemographic correlates.

BACKGROUND Although physical activity is associated with a lower risk of colon cancer, few studies have described the physical activity required for colon cancer prevention in various sociodemographic subgroups. The current study examined the prevalence and sociodemographic correlates of attaining the 2 recommended physical activity criteria for colon cancer prevention among Japanese adults. METHODS The sample included 5322 Japanese adults aged 20 to 79 years. Seven sociodemographic attributes (eg, gender, age, education level, employment status) and the International Physical Activity Questionnaire were assessed via an Internet-based survey. The odds of meeting each physical activity criterion by sociodemographic variables were calculated. RESULTS Overall, 23.8% of the study population met the criterion of ≥ 420 minutes of moderate-intensity activity, and 6.4% met the criterion of ≥ 210 minutes of vigorous activity. Being male, highly educated, employed, living with another person, being married and having a higher household income were significantly correlated with the attainment of recommendations. CONCLUSIONS Participants who met the 2 activity recommendations differed in gender, education level, employment status, marital status, living conditions, and household income. The findings of the current study imply that strategies to promote more intense physical activity in all demographic groups may be necessary.
