Description

The Physical Activity History (PAH) can be used to rapidly measure a person's exercise and physical activity level. It gives moderately detailed information which can be used to estimate a patient's risk for a variety of medical conditions.

Data collection:

(1) amount of time spent on heavy intensity activities

(2) amount of time spent on moderate intensity activities

 Heavy Intensity Activity Intensity in METS/min Cutpoint for Frequent Participation jog or run 8 2 hours/week vigorous racket sports 8 3 hours/week bicycle faster than 10 miles per hour 6 2 hours/week swimming 6 2 hours/week vigorous exercise class 6 3 hours/week vigorous dancing 6 3 hours/week non-job activity (shoveling, weight-lifting, moving heavy objects) 6 3 hours/week vigorous job activity (lifting, carrying, digging) 5 5 hours/week other strenuous sports (basketball, football, skating, skiing) 8 3 hours/week

where:

• MET = metabolic equivalent.1 MET/min is approximately equal to 1 kilocalorie for a 70 kg man

 Moderate Intensity Activity Intensity in METS/min Cutpoint for Frequent Participation non-strenuous sports (softball, shooting baskets, volleyball, ping pong) 4 3 hours/week take walks, hikes, walk to work 4 4 hours/week bowling or golf 3 3 hours/week home exercises, calisthenics 4 3 hours/week home maintenance and gardening (carpentry, painting, raking, mowing) 4 5 hours/week

 Time Spent in Activity during the past year Participation in Activity < 1 hour per month nonparticipation 1 hour up to cutpoint infrequent cutpoint or higher frequent

heavy score in exercise units =

= SUM for all heavy activities ((intensity in NETS/min) * ((number of months of infrequent activity) + (3 * (number of months of frequent activity))))

moderate score in exercise units =

= SUM for all moderate activities ((intensity in METS/min) * ((number of months of infrequent activity) + (3 * (number of months of frequent activity))))

total score in exercise units =

= (heavy score) + (moderate score)

 Total Activity Score Female Male low <= 149 <= 278 low to moderate 150 - 284 279 – 468 moderate to high 285 - 467 469 – 699 high >= 468 >= 700
