—The article by Dr Lee and colleagues¹ on intensity of physical activity and longevity provides additional evidence that physical activity is associated with improved survival. Some points, however, may require further clarification. Different criteria were used to categorize the energy expenditure in specific analytical approaches. Quintiles were shown in Table 1 and in the total energy expenditure multivariate analysis (range, <2524 to >13142 kJ/wk), eight categories were used when analyzing the age-adjusted associations with mortality (range, <2100 to > 14 700 kJ/wk, Table 2), and five categories were used in the multivariate models (range, <630 to >6300 kJ/wk, Tables 3 and 4). Consequently, it is impossible to match the results across the tables. This may confuse readers, and the reasons for presenting the data in such different groupings are not known.

Vigorous, but not nonvigorous, physical activities were associated with longevity. From a practical point of . . . [Full Text PDF of this Article]
