Reducing the prevalence of cigarette smoking among adults is a key health p
romotion target in counties where tobacco consumption is the major preventa
ble cause of ill health. This study describes the patterns and predictors o
f smoking cessation in a representative British survey of women aged 16 to
65. Ir examines the influence on quitting of five factors: socio-economic s
tatus; domestic circumstances; psychological health; tobacco dependence; an
d pregnancy status. Smoking status was measured at the point of recruitment
to the study and at I gear and 2 year follow-up interviews Quit rates at b
oth follow-up points were significantly related to three of the factors: so
cio-economic status; tobacco dependence; and pregnancy status Tobacco depen
dence, as measured by average daily cigarette consumption, was the most pow
erful predictor of a woman's chances of being an ex-smoker at both the I ye
ar and 2 year follow-up interviews. The implications of the findings for he
alth promotion policy are discussed.
