Background:Pedometers are becoming widely accepted for physical activity measurement. To use step data effectively, an index which categorizes steps/day by < 5000, ≥ 5000, ≥ 7500, ≥ 10,000, and ≥ 12,500 steps/day has been previously proposed. However, evidence is insufficient to validate this index compared with health outcomes. This study examined the association of steps/day categories with cardiovascular (CVD) risk.Methods:Cross-sectional data from the National Health and Nutrition Survey of Japan 2006, including 1166 men and 1453 women aged 40–64 years, were analyzed to calculate odds ratios (OR) for having CVD risk including overweight/obesity, blood pressure, high density lipoprotein cholesterol, hemoglobin A1c, and clustered risk factors by steps/day categories.Results:Among men, inverse gradient associations between steps/day categories and CVD risk (overweight/obesity, blood pressure, HbA1c, and clustered risk factors) were observed. Among women, those taking ≥ 5000 steps/day had substantially lower risk of overweight/obesity and high blood pressure compared with those taking < 5000 steps/day. However, additional decreases of OR by taking more steps were modest among women.Conclusions:CVD risk was generally lower with higher steps/day categories. Given the limitations of cross-sectional design, further studies, especially using longitudinal designs, are needed to precisely calibrate the association between steps/day and CVD risk.

Background:Information on specific types of physical activities in which US adults participate is important for community and program development to promote physical activity.Methods:Prevalence of participation and average time spent for 33 leisuretime aerobic activities and 10 activity categories were calculated using self-reported data from 22,545 participants aged ≥ 18 years in the National Health and Nutrition Examination Survey 1999–2006.Results:Overall, 38% of US adults reported no leisure-time physical activities, and 43% reported 1 or 2 activities in the past 30 days. Walking was the most frequently reported activity for both men (29%) and women (38%). Among walkers, the average time spent walking was 198 minutes/week for men and 152 minutes/week for women. The most reported activities for men after walking were bicycling and yard work, and for women were aerobics and dance. For most activity categories, participation was lower among adults aged ≥ 65 years than among younger adults, and among Mexican Americans and non-Hispanic blacks than among non-Hispanic whites. Participation in most categories increased with increasing educational attainment.Conclusions:Participation in physical activity differs by types of activities and demographic characteristics. Physical activity promotion programs should take these differences into account when developing intervention strategies.
