Parental and Peer Influences on Adolescent Smoking Initiation

Introduction The smoking habit is learnt and initiated in adolescence. Among daily smokers, over 85% attempted first cigarette at age of 18 ; almost 65% began smoking regularly by the same age. Malaysian National Health and Morbidity Survey in 2015 reported that 70% of adult smokers started smoking before the age of 18. Ample studies have documented that parents and peers are dominant factors contribute to smoking initiation among adolescents. This study aimed to determine the actual causation factors of smoking initiation among non-smoking school-going adolescents. Methodology Study Design: Prospective Cohort. Study Population: Non-smoking secondary school-going adolescents of form 1 (13 years), form 2 (14 years) and form 4 (16 years). Study Location: Kota Tinggi district, Johor. Sampling: Multistage, proportionate to size and cluster sampling . Respondents were followed-up for one year. Measures: Dependent variable -> smoking status at follow-up (Smoked at least once in past 30 days identified as current smokers). Independent variables -> ―Number of best friends who smoke‖ (0, 1-5), and ―parent(s) smoking status‖ (Yes/No). Data analysis: Descriptive analysis and Multivariable Logistic Regression was employed to determine the associated factors. Results Out of the 1682 non-smoking respondents at baseline, a total of 1282 (74.1%) participated at follow-up. Approximately 1 in 10 non-smoking Malaysian youth initiate smoking after a period of one year. Discussion • This was the first study to determine the factors influencing smoking initiation among non-smoking school-going adolescents in Malaysia. • About 1 in 10 non-smoking Malaysian youth initiated smoking after one year, which is higher than the 5% and 7% among cohorts reported in Portugal 4. • Smoking parent/s was more likely to influence smoking initiation among non-smoking adolescents, which was in consistent with the study among Taiwanese youth 5 that concluded that parents were the dominant role models for the smoking habit development among ...
