Musculoskeletal problems in men and women by flexibility, endurance strength tertiles, school age physical activity, and adult physical activity
| Men | % with symptoms | Women | % with symptoms | |
|---|---|---|---|---|
| Values in parentheses are numbers. The number of subjects by tertile varies because at baseline not all subjects participated in both strength and flexibility tests, and not all subjects answered the questionnaire in 2001. Data for school age physical activity were missing for 12 men and seven women. Data for adult physical activity were missing for four men and five women. | ||||
