Resumen: Ekelund et al. (1) nicely showed that physical inactivity causes an approximate twofold increase in the numbers of deaths compared with those attributable to obesity [BMI (in kg/m2) .30] in a Euro- pean cohort (n 1/4 334,161) that was followed up to 12.4 y on average. Physical activity (PA) levels were estimated by using a standardized questionnaire or in-person interviews and were found to be inversely associated with all-cause mortality at all levels of BMI and waist circumference. Another important finding from their study is that substantial survival benefits may be achieved by fairly small amounts of moderate-intensity PA: that is, ;20 min/d of brisk walking, which is below the current PA recommendations of !30 min/d on most, if not all, days of the week (or !150 min/wk). These important findings in Caucasians are in line with those recently reported in an Asiatic cohort, in whom 15 min/d or 90 min/wk of moderate-intensity PA was associated with lower all-cause mor- tality, even for persons at risk of cardiovascular disease
