Alcohol consumption is a risk factor for various diseases, especially non-communicable diseases (NCDs) and injuries. The reduction of the harmful use of alcohol is mentioned in Target 3.5 of the Sustainable Developmental Goals (SDG). This study aimed to determine factors associated with current alcohol drinking among Malaysians aged 15 years and above. Data from the National Health and Morbidity Survey (NHMS) 2019, a cross-sectional nationwide survey using a two-stage stratified random sampling design, was used. Current alcohol drinking was defined as having consumed any alcoholic beverage in the past 12 months. Descriptive statistics and multiple logistic regression analysis were employed. The prevalence of current drinkers was 11.5%; 95% CI: 9.8, 13.5. The majority (65%) consumed alcoholic beverages in Category 2, which is mainly beer. Current drinkers consumed alcohol mostly once a month (59.0%), one or two drinks (71.1%), on a typical day. Most respondents had six or more drinks less than once a month (27.6%). Sex, age, ethnicity, education, employment, and smoking were found to be significantly associated with current alcohol drinking. Marital status, locality of residence, and household income were not significantly associated. Alcohol drinking is a problem among certain vulnerable groups and should be tackled appropriately.

Background: Malaysia has the highest rate of diabetes mellitus (DM) in the Southeast Asian region, and has ongoing air pollution and periodic haze exposure. Methods: Diabetes data were derived from the Malaysian National Health and Morbidity Surveys conducted in 2006, 2011 and 2015. The air pollution data (NO_x, NO₂, SO₂, O₃ and PM₁₀) were obtained from the Department of Environment Malaysia. Using multiple logistic and linear regression models, the association between long-term exposure to these pollutants and prevalence of diabetes among Malaysian adults was evaluated. Results: The PM₁₀ concentration decreased from 2006 to 2014, followed by an increase in 2015. Levels of NO_x decreased while O₃ increased annually. The air pollutant levels based on individual modelled air pollution exposure as measured by the nearest monitoring station were higher than the annual averages of the five pollutants present in the ambient air. The prevalence of overall diabetes increased from 11.4% in 2006 to 21.2% in 2015. The prevalence of known diabetes, underdiagnosed diabetes, overweight and obesity also increased over these years. There were significant positive effect estimates of known diabetes at 1.125 (95% CI, 1.042, 1.213) for PM₁₀, 1.553 (95% CI, 1.328, 1.816) for O₃, 1.271 (95% CI, 1.088, 1.486) for SO₂, 1.124 (95% CI, 1.048, 1.207) for NO₂, and 1.087 (95% CI, 1.024, 1.153) for NO_x for NHMS 2006. The adjusted annual average levels of PM₁₀ [1.187 (95% CI, 1.088, 1.294)], O₃ [1.701 (95% CI, 1.387, 2.086)], NO₂ [1.120 (95% CI, 1.026, 1.222)] and NO_x [1.110 (95% CI, 1.028, 1.199)] increased significantly from NHMS 2006 to NHMS 2011 for overall diabetes. This was followed by a significant decreasing trend from NHMS 2011 to 2015 [0.911 for NO₂, and 0.910 for NO_x]. Conclusion: The findings of this study suggest that long-term exposure to O₃ is an important associated factor of underdiagnosed DM risk in Malaysia. PM₁₀, NO₂ and NO_x may have mixed effect estimates towards the risk of DM, and their roles should be further investigated with other interaction models. Policy and intervention measures should be taken to reduce air pollution in Malaysia.

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....

Introduction: Polysubstance useis the use of more than one non-prescribed licit or illicit substance at one time. This is a common phenomenon, but little is known about the severity and the various substances used by adults in Malaysia.Objective: To determine the pattern of polysubstance use and its associated factors among general adults in Malaysia.Methodology: This was a secondary data analysis from the National Health and Morbidity Survey (NHMS) 2019), a cross-sectional population survey with a two-stage stratified random sampling design. A total of 10,472 Malaysians aged 18 years and above participated in this survey. Polysubstance use was defined as concurrent use of more than one substance, either alcohol, tobacco, or drugs (opioids, marijuana, amphetamine/ methamphetamine or kratom). A latent class analysis (LCA) was used to identify the membership of polysubstance groups. The association of class membership with demographic profiles was examined using Multinomial Logistic Regression analysis.Results: Fit indices (AIC = 16458.9, BIC = 16443.6) from LCA supported 3 classes solution: Class 1; “moderate-drug” group primarily combination used of tobacco and alcohol (2.4%), Class 2; “high-drug” group using multiple substance including kratom (0.3%) and Class 3; “low-drug” group reporting minimal alcohol and tobacco use or non-user (97.3%). The multinomial model showed young adults (18–40 years) had a higher likelihood of being polysubstance users both for moderate-drug class (OR = 4.1) and high-drug class (OR = 3.9) compared to older age (≥60 years). Chinese (OR = 18.9), Indian (OR = 23.3), Indigenous Sabah & Sarawak (OR = 34.6) and others ethnicity (OR = 8.9) showed higher odds of being moderate-drug users than Malays. The greater odds of moderate-drug use for males (OR = 35.5), working groups (OR = 1.5) and low education level group (OR = 3.2).Conclusion: Our study highlights patterns and demographics related to the use of polysubstances among adults in Malaysia. These results would help formulate specific prevention programmes for these high-risk groups.

Background: Small cigarette pack sizes contain less than 20 cigarette sticks in a pack. Smaller packs may suggest lower costs, increasing affordability among lower-income users, especially the younger generation, which could lead to tobacco-related diseases and economic costs, including human capital lost results from tobacco-attributable morbidity and mortality. This concern has caused many countries to ban the sale of single cigarette sticks or kiddie packs. However, small cigarette pack sizes were proposed recently to be reintroduced by the tobacco industry with an excuse to prevent consumers from buying illicit cigarettes. This would demean efforts in combating tobacco consumption based on the existing tobacco control policies to prevent minors from purchasing cigarettes. Given the competing influences of affordability and availability of tobacco on consumption and the dearth of evidence-based review on the impact of pack size on smoking, this systematic review was conducted to identify the link between kiddie packs and smoking specifically on the initiation of smoking, urge/tendency to buy cigarettes among the general population and attempt to reduce cigarette consumption and prevalence of smoking using kiddie packs among current smokers. Methods: We include all studies except for reviews, guidelines, conference papers, commentaries, editorials, or opinion pieces. A database search was conducted in PubMed, EMBASE, CENTRAL, Web of Science and Scopus on 27 November 2021. The results were presented in the form of narrative synthesis under four groups: initiation of smoking; urge/tendency to buy cigarettes; the prevalence of smoking, and attempt to reduce cigarette consumption. The literature search identified 1601 articles, of which 21 articles had met the inclusion criteria. The methodological quality of all included articles was determined using a validated 16-item quality assessment tool (QATSDD). The average quality score for all papers was 34.8%. Discussion: Given the diverse study settings of the articles and despite the challenges of the methodological quality of some articles, this review provides some evidence that kiddie packs may increase the urge/tendency to buy cigarettes and mixed evidence on the attempt to reduce cigarette consumption. This review also found some evidence that kiddie pack purchasing among teenage smokers was higher compared to adults. However, we are uncertain about the link between kiddie packs and smoking initiation. Nevertheless, since most studies were of low quality, further high-quality studies are needed to conclude about the impact of kiddie packs on smoking to assist the policymakers and stakeholders in formulating new policies and strengthening existing strategies related to the kiddie packs.

Adolescents frequently face emotional and social challenges that make them particularly vulnerable to feelings of loneliness. This study aimed to determine the national prevalence of loneliness among Malaysian secondary school students and to identify the psychosocial and familial factors associated with it. A cross‐sectional study was conducted using a multi‐stage stratified cluster sampling design to ensure the representativeness of all secondary school students from Form 1 to Form 5 in Malaysia. A total of 239 secondary schools were chosen, and 33,523 students participated. The Malaysia Global School‐based Student Health Survey (GSHS) 2012 self‐administered questionnaire was used. The students who responded “most of the time” or “always” to feeling lonely during the past 12 months were categorized as lonely. Multiple logistic regression was used to identify the associated factors. The prevalence of loneliness among secondary school students in Malaysia was 16.2%, with females having the highest prevalence at 20.8%. Multiple logistic regression revealed that students with depression symptoms had a ninefold higher likelihood of feeling lonely. Poor parental or guardian connectedness and bonding were significantly associated with feeling lonely. Furthermore, students whose parents are separated had a 40% higher risk of experiencing loneliness. Loneliness among secondary school students was more evident in those with depression symptoms. Addressing loneliness among secondary school students in Malaysia necessitates a concerted effort to prevent the occurrence of all modifiable factors contributing to this issue.
