Abstract:
INTRODUCTION Over the last 40 years, high smoking prevalence has been reported throughout Cuba, including in Cienfuegos city in the central part of the island. OBJECTIVES Determine smoking prevalence and potential associated risk factors in Cienfuegos city for 2010-2011. METHODS A descriptive cross-sectional study was conducted in Cienfuegos city in the context of CARMEN (Collaborative Action for Risk Factor Prevention & Effective Management of Non-communicable Diseases), a PAHO multi-country initiative for a multidimensional approach to chronic non-communicable diseases. Participants totaled 2193 (aged 15-74 years), randomly selected through complex probabilistic three-stage sampling. Variables examined in relation to smoking included age, sex, skin color, civil status and educational level. RESULTS Approximately 25% of those surveyed were smokers (30.3% of men and 21.0% of women). For men, prevalence was highest in the groups aged 25-34 and 55-64 years; for women, in the group aged 45-54 years. Concerning skin color, smoking rates were higher among black and mestizo persons (29.5%); and concerning civil status, higher among those who were separated, widowed or divorced (30.0%). Smoking prevalence fell with higher educational level; in keeping with that trend, the university-educated group had the lowest prevalence (16.2%). CONCLUSIONS Although one in four Cienfuegos residents aged ≥15 years smoked in 2010-2011, prevalence there is lower than in previous surveys. Knowledge of differences observed in age, sex, skin color, civil status and educational level can be useful for planning future smoking prevention and control actions.
