Table 3.

The proportion of deaths that might be prevented if all participants achieved at least the physical activity level indicated, the Allied Dunbar National Fitness Survey

Activity category^a	Population attributable fraction % (95 % CI)
Activity category^a	Whole population^b	Inactive population^c
Low	8.9 (4.2–13.4)	21.4 (10.2–31.1)
Moderate	15.1 (5.7–23.6)	24.1 (9.3–36.5)
Active	20.6 (6.9–32.3)	27.9 (9.6–42.5)

Adjusted for age, sex, social class, marital status, health authority, season, alcohol intake and smoking status

Assuming causality between physical activity and mortality, PAFs show the percentage of deaths that might be prevented if all participants achieved at least the physical activity level indicated

^aThe number of 20 min bouts of moderate/vigorous activity per month, where low: at least 1; moderate: at least 15; active: at least 30 ‘bouts’

^bThe proportion of deaths that might be prevented if all participants achieved at least the physical activity level indicated

^cThe proportion of deaths of inactive individuals that might be prevented if all inactive participants achieved the physical activity level indicated
