Factors related to smoking behavior of students in higher education institutions, Chonburi Province

Abstract

This analytical cross-sectional study examined factors associated with smoking behavior among students in higher education institutions in Chonburi Province. A total of 296 students aged 18–30 years were recruited, and data were collected between July and October 2025 using a structured questionnaire covering demographics, smoking behavior, knowledge and attitudes toward smoking, stress, smoking among close contacts, exposure to online tobacco advertising, and accessibility of tobacco products. Data were analyzed using descriptive statistics and Spearman’s rank correlation coefficient, with statistical significance set at 0.05. Based on the demographic data of the sample, the majority were female (78.70%), with a mean age of 20.12 ± 1.91 years.

Regarding the study findings, the students demonstrated a high level of correct knowledge and positive attitudes toward smoking, while reporting a low level of stress (mean stress score = 1.93 ± 1.03).  The prevalence of ever smoking was 9.50% and current smoking was 6.10%, with 89.13% of current smokers using electronic cigarettes. Nearly half (49.30%) reported having close contacts who smoked, and 65.20% reported exposure to online tobacco advertising and easy access to tobacco products near their institutions. Factors significantly associated with smoking behavior (p < 0.05) included year of study (r = .21), knowledge about smoking (r = -.27), smoking among close contacts (r = .28), exposure to online tobacco advertising (r = .20), and accessibility of tobacco products (r = .31). Therefore, higher education institutions and relevant agencies should collaborate to promote proper smoking-related knowledge and attitudes among students. Smoking cessation services via peer and family networks should be implemented alongside strict smoke-free environment controls and restricted cigarette access around campuses to foster a sustainable smoke-free society.
