Factors Associated with Cigarette Consumption in a High Socioeconomic Level Peruvian District

Objective: To identify and classify the socioeconomic factors associated with cigarette consumption in a high socioeconomic level district in Peru. Methods: A cross-sectional study using data from the “Health and Determinants Census of the San Borja District” (2021–2022) with 49,082 respondents. The analysis focused on individuals who answered whether they had smoked cigarettes in the past 12 months. Variables such as cigarette consumption, sex, age, educational level, marital status, employment status, and others were analyzed using binary logistic regression and Chi-Squared Automatic Interaction Detection (CHAID) decision tree analysis. Results: The smoking rate was 3.70%. Adults without a partner were 1.46 times more likely to smoke. Those living in shared apartments were 1.38 times more likely, and individuals without their own home were 2.01 times more likely. Men were 2.574 times more likely to smoke than women. The CHAID decision tree revealed that job instability was a key factor for men, while economic crises and household criminal incidents were significant for women. Conclusions: Job instability in men and precarious living conditions in women were associated with cigarette consumption. The main socioeconomic profile of cigarette smokers included being male, not owning a home, and being single.
