Objective This study aimed to estimate the prevalence of walking behavior and investigate demographic correlates of recommended physical activity levels with five domains (exercise, commuting, working, shopping, and other movement) of walking behavior among Japanese adults aged 30-49.
Methods The sample was 5,009 Japanese adults collected from the registrants of a Japanese social research company. The study design was a cross-sectional study using an Internet questionnaire. The dependent variable was meeting physical activity recommendation levels (more than 150 min/1week) . Independent variables were demographic variables (e.g., gender, age, educational level, household income level, hour per day with TV watching, and hour per day with internet usage) . Logistic regression analysis was utilized.
Results Of all participants, 45.5% of men and 44.8% of women met physical activity recommendations. Regardless of meeting recommended physical activity levels, they walked for exercise less than 20%. The characteristics of those who met the recommendation levels were higher education, long Internet use and having a small number of children for men, and higher education, higher income and having a small number of children for women. As compared with those who did not meet physical activity recommendations, in lifestyle time men walked for shopping and other movement and women walked for shopping.
Conclusion Commuting and shopping for men and shopping for women were identified as a key factor for increasing walking behavior. It would be necessary for women to develop an intervention program which considers demographic factors such as marital status, employment status and household children.
