The influence of family environment on the evolution of tobacco consumption in 2 trial towns and 2 control towns in Switzerland

: As part of a study on cardiovascular risk factor modification in four Swiss cities (National Research Program 1A, "Primary Prevention of Cardiovascular Disease in Switzerland") between 1977 and 1981, the influence of family members on changes in tobacco consumption was investigated. In this study there were two intervention cities, with a community health education program, and two reference cities. The net decrease of regular smokers was significantly more important in the intervention cities (-3.6%, p less than 0.05), however there was no significantly different pattern for family members. In contrast, there was a significant influence among adult family members both for the decrease (p = 0.0001) and the increase (p less than 0.005) in tobacco consumption.
