The pattern in prevalence and sociodemographic factors of smoking in Malaysia, 2011-2019: Findings from national surveys.

INTRODUCTION: Smoking is a major contributor to morbidity and mortality worldwide, with Malaysia no exception. Through the Ministry of Health and other ministries in the government of Malaysia, numerous anti-smoking measures have been introduced to prevent and control smoking in the country. Continuous monitoring of smoking prevalence in the community is essential in order to evaluate the effectiveness of anti-smoking policies. This study aims to update the sociodemographic factors associated with smoking in the past decade in Malaysia. METHODS: The study utilized data from three national household surveys in Malaysia, namely the Global Adult Tobacco Survey (GATS) 2011, the National Health and Morbidity Survey (NHMS) 2015 and the National Health and Morbidity Survey (NHMS) 2019. These surveys adopted a multistage stratified sampling design that represents the population in Malaysia. Smoking status was determined based on the GATS protocol and definitions. Complex sample design estimates and complex multivariable logistic regression were used in the analysis. RESULTS: A total of 4250, 21410 and 11111 respondents aged ≥15 years participated in GATS 2011, NHMS 2015 and NHMS 2019, respectively, with a response rate between 85% and 87%. The prevalence of smoking was 23.1% (95% CI: 21.2-25.2) in 2011, 22.8% (95% CI: 21.9-23.8) in 2015 and 21.3% (95% CI: 19.9-22.8) in 2019. The prevalence was consistently higher in males (40.5-43.9%), adults aged 25-44 years (25.4-29.0%), Malay (22.6-24.7%), other ethnicities (30.0-35.0%), and the self-employed (33.7-44.6%). Multiple logistic regression analysis showed that the adjusted odds ratio (AOR) of smoking was higher in males, in younger and middle age groups, Malays, and those with lower education level. CONCLUSIONS: There were slight changes in the sociodemographic factors of smoking in the past decade in Malaysia. Stern measures and more aggressive strategies are needed to address all the risk factors in controlling smoking behavior in the country.

Factors Associated with the Acceptability of Mass Drug Administration for Filariasis: A Systematic Review.

Mass drug administration (MDA) has been implemented as a tool to eliminate lymphatic filariasis. Acceptability among susceptible populations is crucial to achieving MDA effective coverage. This systematic review aims to present and systematically determine the factors associated with the acceptability of MDA. Articles related to factors associated with acceptability were collected electronically from three different databases (Scopus, Web of Science, and PubMed). Four pairs of independent reviewers screened the titles and abstracts of the collected data, stored in EndnoteX7, against the inclusion criteria. Afterwards, the included articles have been critically appraised to assess the quality of the studies using the Mixed Method Appraisal Tool (MMAT). Of the 68 articles identified, 11 were included in the final review. Knowledge, awareness, attitude and perceptions, communications, delivery and accessibility of MDA, gender, and age are the factors associated with MDA acceptability. Community acceptance remains a challenge in the implementation of MDA. To expand MDA coverage in all endemic countries, there is a strong need to address the factors influencing community acceptance of MDA.

Polysubstance use among adolescents in Malaysia: Findings from the National Health and Morbidity Survey 2017.

BACKGROUND: Polysubstance use is defined as the use of more than one non-prescribed licit or illicit substance either concurrently or simultaneously. This study aimed to determine the prevalence of single substance users and polysubstance users and 'their associated factors among adolescents in Malaysia. METHODS: This study was a secondary data analysis from the National Health and Morbidity Survey (NHMS) 2017, a cross-sectional survey conducted among Malaysian school-going adolescents aged 13 to 17. The NHMS utilised a two-stage stratified cluster sampling. Multivariate Multinomial Logistic Regression analysis was applied. RESULTS: The overall prevalence of single substance use and polysubstance use among adolescents were 17.2% and 5.1% respectively. The multinomial model showed a higher likelihood of being single or polysubstance user among male (single user OR = 3.0, poly user OR = 4.6), others Bumiputeras vs Malay (single user OR = 1.7, poly user OR = 5.3), those who live with a single parent (single user OR = 1.2, poly user OR = 1.4), involved in truancy (single user OR = 1.7, poly user OR = 3.6) and being bullied (single user OR = 1.3, poly user OR = 3.4), those who had lack of peer support (single user OR = 1.3, poly user OR = 1.4), poor parental bonding (single user OR = 1.4, poly user OR = 1.8), depression (single user OR = 1.4, poly user OR = 3.2) and those who had no close friend (single user OR = 1.3, poly user OR = 2.7). CONCLUSION: Our study highlighted multiple significant associated factors of single and polysubstance use among adolescents in Malaysia. This result can assist in the development of specific intervention and prevention programs targeting high-risk groups.

Risk Factors for Illicit Drug Use Among Malaysian Male Adolescents.

This study was carried out to determine the prevalence of illicit drug use and its associated factors among male adolescents in Malaysia. Data of 13 135 adolescents were extracted from the National Health and Morbidity Survey 2017, a cross-sectional survey among school-going adolescents in Malaysia aged between 13 and 17 years, using a 2-stage stratified cluster sampling. A complex sample design analysis and multiple logistic regression analysis were applied. The overall prevalence of lifetime illicit drug use among male adolescents was 6.6%. The multivariable model showed that illicit drug use among male adolescents were associated with younger age, rural school area, marital status of parent, current smoker, ever having sex, truancy, involved in physical fight, and lack of peer support. The findings from this study can assist community and relevant authorities in their efforts to combat illicit drug usage among adolescents using intervention programs that diminishes risk factors and enhances the protective factors.
