  1. y years, SD standard deviation, n number of subjects, BMI body mass index. The Grimby physical activity scale ranges from 1-6, least to hardest physical activity. A level of 4 corresponds to moderate exercise 1-2 hours a week, a level of 5 is equal to moderate exercise at least 3 hours a week, and a level of 6 is equal to hard or very hard exercise several times a week.
