Since smoking causes 80-90% of lung cancers in both men and women, it is important to look at smoking behaviour.
Young men and people with less education are more likely to smoke, tobacco advertising targets these groups.
Men tend to smoke to increase positive feelings while women smoke to shield negative feelings. This is consistent with research that indicates that more female smokers than male smokers are depressed - an estimated 80% of women with a history of depression are addicted to tobacco.
Early predictors of smoking at 18-19 years of age include lower parental education, one parent household, drinking alcohol at ages 11-12 and a higher drive for thinness at ages 11-12.
Among adolescent females, eating disorder symptoms, weight control attempts and thoughts about weight are prospectively related to smoking initiation. These factors were not predictive of smoking initiation in males
