This study explores the correlates of sociodemographic factors, smoking, and caloric knowledge to body mass index awareness with a focus on Malaysia. Logistic regressions were estimated to examine sociodemographic factors associated with body mass index awareness. More than half of respondents were unaware of their body mass index (54.8%). Age was negatively associated with body mass index awareness. Adults without formal education were less likely to know their body mass index than those with tertiary‐level education. Adults were less likely to be aware of their body mass index if they engaged in smoking. Adults with knowledge of the definition of calories were more aware of their body mass index than others. The findings emphasize the urgent need for a forthcoming sociodemographic factors‐specific policy directed toward improving body mass index awareness to lower the prevalence of obesity in Malaysia.

Smoking is one of the main factors that causes various diseases. The objective of the present study is to investigate factors determining smoking behaviour among adults. The present study used instrumental variable (IV) regressions to estimate the effects of demographic and knowledge factors on participation decision and amount decision of smoking. Nationally representative data of a developing country (Malaysia) was used. Contrary to popular belief, knowledge was found to be positively associated with the propensity to smoke, as well as the amount of smoking. Age, gender, wealth index, educational level, ethnicity, marital status and house locality were significantly associated with smoking. Males were more likely to smoke and smoked more than females. Educational level reduced the likelihood and amount of smoking. Malays and married individuals were less likely to smoke than non-Malays and unmarried individuals. Urban dwellers smoked more cigarette relative to rural dwellers. In terms of policy implication, it is suggested that intervention measures directed toward reducing the prevalence of smoking should not pay too much attention to improving the knowledge of health effects of smoking among Malaysian adults. Anti-smoking policies must be designed carefully by taking into account of the demographic factors which are correlated with the likelihood and amount of smoking. The present study is the first of its kind that includes knowledge as a separate variable for analyses and uses IV regressions to analyse participation decision and amount decision of smoking.

Background: The rising prevalence of non-communicable diseases (NCDs) has become a serious public health issue. Among the multi-factorial drivers behind NCDs are modifiable health risk factors, most notably, physical inactivity. Objective: In response to the nearly global policy priority of encouraging regular participation in physical activity, the objective of the present study is to examine the factors that determine participation in physical activity among Malaysian adolescents. Methods: Nationally representative data consisting of a large sample size was used. A censored regression model was developed to estimate the likelihood of participation and time spent on physical activity. Results: There are significant relationships between physical activity and gender, ethnicity, self-rated academic performance, maternal education, household size and time spent on physical education. Conclusion: The present study provides new insights into the factors affecting physical activity participation among adolescents. Specifically, self-rated excellent aca demic performance, household size and physical education can increase the likelihood of being physically active. Evidence of the present study implies that policy makers should pay special attention to females, Chinese, adolescents with self-rated poor academic performance and adolescents who have low maternal education.

Objective: The identification of susceptible non-smoking adolescents is an essential step in reducing smoking initiation among adolescents. The aim of this study was to examine the prevalence and factors associated with smoking susceptibility among non-smoking school-going adolescents in Malaysia. Design: Cross-sectional study. Setting: Primary and secondary schools in Malaysia. Participants: 11 246 non-smoking school-going adolescents. Outcome measures: The prevalence and factors associated with smoking susceptibility among non-smoking school-going adolescents in Malaysia. Results: Approximately 14% of non-smokers were susceptible to smoking, and the prevalence of susceptibility was significantly higher among males, ever-smokers and e-cigarette users. The odds of susceptibility to smoking were higher among males, e-cigarette users, those aged 12 years and under and those who had ever smoked or tried cigarettes. Students from schools with educational programmes on the health effects of second-hand smoke (SHS) and who perceived smoking to be harmful were less likely to be susceptible to smoking. Conclusion: Smoking susceptibility is prevalent among school-going adolescents. A comprehensive approach that enhances or reinforces health education programmes on the adverse health effects of smoking and SHS among school children, that considers multiple factors and that involves all stakeholders is urgently needed to reduce the prevalence of smoking susceptibility among vulnerable subgroups, as identified from the present findings.

Chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) is associated with adverse effects. However, NSAIDs are among the most popular pain killers and easily available over the counter. This study aimed to determine the prevalence of NSAIDs use in Malaysian adults and among those with chronic diseases such as arthritis, kidney disease, hypertension, heart disease and asthma. It also examined the factors associated with NSAIDs use. Data from the National Health Morbidity Survey (NHMS) 2011, a nation-wide survey was analysed. A total of 18231 respondents aged 18 years and above responded to this module. Multivariate logistic regression was used to investigate the association between NSAIDs use and associated factors. The overall prevalence of NSAIDs use among Malaysian adults was 14.2% (95%CI 13.3-15.1). Of the respondents, 4.2% (95%CI 3.8-4.7) took NSAIDs once daily. NSAIDs use was highly associated with those who were ever-told to have arthritis (aOR: 3.03; 95%CI 2.60-3.52) and have difficulty of performing daily activities or work (aOR: 2.06; 95%CI 1.86-2.28). Those who were ever-told to have kidney disease (aOR: 2.36; 95%CI 1.74-3.20), ever-told to have asthma (aOR: 1.36; 95%CI 1.17- 1.58), ever-told to have heart disease (aOR: 1.34; 95%CI 1.08-1.65), known hypertension (aOR: 1.22; 95%CI 1.08-1.37) also were associated with NSAIDs use. By socio-demographic profiles, NSAIDs use was positively associated with those who have government benefit scheme or private health insurance (aOR: 1.44; 95%CI 1.31-1.58), higher education level (aOR: 1.35; 95%CI 1.20-1.51), higher household income (aOR: 1.26; 95%CI 1.11-1.44, aOR: 1.12; 95%CI 1.02-1.24), currently working (aOR: 1.25; 95%CI 1.13-1.39) and female (aOR: 1.17; 95%CI 1.07-1.28). NSAIDs use was less likely among those aged 60 years and above (aOR: 0.83; 95% CI 0.72-0.97), Chinese (aOR: 0.41; 95% CI 0.36-0.47) and ‘Others’ ethnicity (aOR: 0.82; 95% CI 0.67-0.99) compared to Malay ethnicity. NSAIDs use is prevalent in Malaysian adults and associated with co-morbidities and higher socio-demographic status, thus appropriate awareness should be promoted and highlighted in the community.

Estimating the factors affecting participation decisions of physical activity has continuously received significant research attention. However, the effects of income and demographic factors on physical activity intensity have seldom been studied thoroughly, especially in developing countries. To fill this research gap, the income and demographic determinants of the time spent on both vigorous- and moderate-intense physical activities among Malaysian adults are estimated using a censored regression model. The results are comparable to those in developed countries, such as the USA and Australia, which show that income, age, education level and being unemployed are negatively associated with the time spent on both vigorous- and moderate-intense physical activities. Compared to females, males spend more time on vigorous-intense physical activity but less time on moderate-intense physical activity. The present study suggests that acquiring a better understanding of the factors that can affect physical activity intensity is important for policy development.

Background: This study examines the effects of sociodemographic factors on participation in vigorous and moderate physical activity and how they vary across bodyweight group (underweight, normal, overweight, obese I, obese II). Methods: This study uses a nationally representative data with a sample of 10141 respondents. Bivariate and multivariate analyses are stratified by bodyweight group. The intensity of physical activity is measured using metabolic equivalent (MET). Vigorous physical activity has >6 MET, while moderate physical activity has ≤6 MET. Results: Several important findings are noteworthy. First, age has a positive impact on moderate physical activity among obese I individuals but a negative impact on moderate physical activity among obese II individuals. Second, education is significant in determining participation in all intensity levels of physical activity among obese I individuals. Third, higher income obese II individuals spend less time in vigorous physical activity than their lower income counterparts. However, higher income overweight and obese I individuals spend less time in moderate physical activity compared with those who have lower income. Fourth, overweight, obese I and obese II males spend more time in vigorous and total physical activity than their female counterparts, but they allocate less time for moderate physical activity. Conclusions: It appears that sociodemographic factors play an important role in determining participation in vigorous and moderate physical activity among overweight and obese adults. We conclude by discussing implications for policies directed towards promoting physically active lifestyle among overweight and obese adults who are unlikely to spend time in physical activity.
