A repeat survey was conducted in 2007 in the same Panchayat
area selected by cluster sampling technique. Each ward was
treated as a cluster similar to the baseline survey. From each of
the 12 wards it was decided to survey 250 individuals (125
males and 125 females) in the age group of 25e74 years. Instructions
were given to the volunteers to select approximately
500 individuals (males 250) from each 10 year age group of
25e74 years as per the WHO STEPS guidelines.32 We collected
data from 2517 individuals above the age of 30 years. The
interview schedule used for the post intervention survey was
the same as that of the baseline survey. All the measurement
tools were same for baseline and post intervention surveys
