Smoking behavior and its determinants among women in Concordia, Argentina.

Abstract

This study assessed smoking, sexual, and reproductive behaviors as determinants of smoking behavior in women from Concordia, Province of Entre Ríos, Argentina, a population with a low incidence of lung cancer and a high incidence of cervical cancer. Interviewers administered structured, close-ended questionnaires to 1,028 women, aged at least 15 years, living in a random sample of households. We calculated the prevalence of smoking-related variables by age group and used a multivariate logistic regression model to identify various behavioral determinants of smoking. Overall, 36% of the women reported having ever smoked, and 23% were current smokers. At least 50% of the women who ever smoked in each age group smoked less than 10 cigarettes per day. The main determinants of ever having smoked were single marital status (OR=1.64, 95% CI=1.01-2.66) and reporting two or more lifetime sexual partners (two or three: OR=2.25, 95% CI=1.63-3.07; four: OR=3.54, 95% CI=2.10-5.08). No association with socioeconomic level, reproductive characteristics, or variables related to health behavior was observed. We conclude that the prevalence of smoking was high, particularly among women aged 35-54 years, and was strongly associated with sexual behavior. Although women seem to be starting to smoke at younger ages compared with women in the past, the younger cohorts do not seem to be taking up the practice to the same extent as the older cohorts. Antismoking interventions and appropriate control measures are still necessary.
