India - SAGE Physical Activity Validation Study 2010

Using the same study population from the 2005 SAGE Pilot, this 2010 sub-study on physical activity (measured using accelerometer and self-reported using the Global Physical Activity Questionnaire(GPAQ)) was conducted in a sample of 200: 72 men and 128 women between the ages of 49 and 90 years in Jodhpur, Rajasthan, India. Respondents wore ActiGraph (Pensacola, FL) GT3X accelerometers at the hip (~1 cm toward the midline from the iliac crest) for seven consecutive days, with the accelerometer set to record data for all three axes at 60 second epochs. Anthropometric dimensions (weight, height, body mass index]) were obtained following standard practices. The SAGE PA VALIDATION sub-study used a short survey questionnaire derived from the larger SAGE survey instrument and covered a range of topics, including economic well-being and work history, health state and functioning, preventive health behaviours, social cohesion, and time-use. The interview process also included a timed 4-meter walk and grip strength.
