Self-reported information on adult physical activity levels has been collected at ages 31, 36, 43 and 53 years.


At ages 36 and 43, questions on the frequency and duration of participation in a range of leisure time activities and sports, outdoor activities and exercise (including work-related activity) in the previous month were collected by nurse interviewers during home visits.


Using data at age 36 years, a set of four physical activity variables have been derived (see Kuh et al 1992).  These are: physical activity during the working day; cycling and walking; heavy gardening and DIY; sports and recreational activities. Each of these variables categorises people into 3 groups from most active through to least active, except for physical activity during the working day which categorises people into 4 groups, with more details of how these categories are assigned given in the variable descriptions below.

At age 43 years a similar summary variable was derived for sports and recreational activities.


These derived variables have been recoded so that 0 is always least active, 1 is less active and 2 is most active (except for the physical activity during the working day variable, where an additional variable has been created to be coded in the same way but the 4 category variable is also available). 


In 1999, at age 53, a single, 3 part question on participation in sports, vigorous leisure activities or any exercises in spare time not including getting to and from work in the past 4 weeks was asked as part of the CAPI interview.  Cohort members reported whether or not they participated in any such activities, how many occasions in the last 4 weeks they had done these activities and the number of occasions on which exercise made them sweaty or out of breath. These variables were used to derive a 3 category variable equivalent to similar variables on sports and recreational activity at ages 36 and 43 years.
