 +At age 31, people were asked to rate their fitness level and to state how often they took part in several sports and exercise options.

 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.  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.

 At age 43 years a similar summary variable was derived for sports and recreational activities. 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 //(EXWORK82C)// has been created to be coded in the same way but the category variable is also available). +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 //(EXWORK82C)// has been created to be coded in the same waythe four-category variable is also available).

-In [[questionnaires:2009|2006-10]], at age 60-64, study members were asked to complete a pre-assessment questionnaire. This contained questions on physical activity associated with work and commuting, as well as frequency of undertaking a range of activities, such as sports, gym, team games, DIY, gardening and household chores in the last 12 months.  Study members were also invited to wear a CamNtech Actiheart monitor for seven days. The Actiheart has two clips which attach directly to standard ECG electrodes and was worn on the chest. It was used to measure activity levels and heart rates. +In [[questionnaires:2009|2006-10]], at age 60-64, study members were asked to complete a pre-assessment questionnaire which included questions based on the EPAQ2.

-In [[questionnaires:2015|2014-16]], at age 68-70, study members were given the option to complete an additional form and wear an accelerometer for seven days.  The separate activity questionnaire included questions on typical levels of activity, frequency of various activities, past activity, falls, joints and bones.  The accelerometer, Gulf Coast Data Concepts X16-1C, was worn on the hip and was used to measure movement and impact of activity during habitual physical activity. A time sheet was also completed so the times when the monitor was not worn could be documented.  +In [[questionnaires:2015|2014-16]], at age 68-70, study members were given the option to complete an additional form and wear an accelerometer for seven days.  The separate activity questionnaire included questions on typical levels and frequency of current activity, overall levels of physical activity throughout adult life, falls, joints and bones.  The accelerometer, Gulf Coast Data Concepts X16-1C, was worn on the hip and was used to measure movement and impact of activity during habitual physical activity. A time sheet was also completed so the times when the monitor was not worn could be documented.  \\  
 +Around 90% of participants chose to complete the physical activity questionnaire, with around half of those also agreeing to wear the actvity monitor.

 +**Please Note** that the physical activity standard basket contains only the most commonly-used summary variables on this topic. A large amount of physical activity data have been collected in adulthood, including frequencies and duration of many different types of exercise, activity related to work and everyday routines, and detailed accelerometry data.<html><p></html> If you are specifically interested in physical activity you are strongly advised to investigate this subject on [[skylark:skylark|Skylark]] to view the full, detailed variable metadata.<html><p></html>
