Change in physical activity among subjects initially in the “active” group** over 4–8 months follow-up, EC participants vs. controls (n=33)
| EC participants n=20 | Controls n=13 | p value unadjusted | p value adjusted * | |||
|---|---|---|---|---|---|---|
| Baseline | Follow-up | Baseline | Follow-up | |||
| Physical activity/week in mean minutes/week | 690 | 430 | 530 | 160 | 0.62 | 0.49 |
| Physical activity/week in mean kcal/week | 2,970 | 1,840 | 2,130 | 640 | 0.92 | 0.37 |
| Walking for exercise/week1 (mean kcal/week) | 480 | 140 | 720 | 90 | 0.21 | 0.54 |

| Exercise/week3 (mean kcal/week) | 250 | 60 | 30 | 10 | 0.16 | 0.13 |
| Leasure activity/week4 (mean kcal/week) | 70 | 30 | 10 | 0 | 0.35 | 0.91 |
| Percentage who are active** | 100% | 65% | 100% | 20% | 0.02 | 0.17 |
Means were calculated as geometric means.
*Adjusted by age, gender, race, education and health status in a multivariate linear regression model
**Active individuals were defined as those who, at baseline, reported at least ten episodes in the last 2 weeks of moderate physical activity of at least 30 min duration, while inactive or “low activity” individuals were those with less activity.
1) Walking for exercise; 2) House hold chores was comprised of moderately strenuous housework, mowing the lawn, raking the lawn; 3) Exercise was comprised of hiking, jogging, biking, exercise cycle, aerobics/aerobic dance, calisthenics/general exercise, and swimming; and 4) Recreational activity was comprised of dancing, bowling and golf.
