Prevalence and correlates of roll-your-own smoking in Thailand and Malaysia: Findings of the ITC-South East Asia Survey

Young D, Yong HH, Borland R, Ross H, Sirirassamee B, Kin F, et al.

Nicotine Tob Res, 2008 May;10(5):907-15.

Roll-your-own (RYO) cigarette use has been subject to relatively limited research, particularly in developing countries. This paper seeks to describe RYO use in Thailand and Malaysia and relate RYO use to smokers' knowledge of the harmfulness of tobacco. Data come from face-to-face surveys with 4,004 adult smokers from Malaysia (N = 2,004) and Thailand (N = 2000), collected between January and March 2005. The prevalence of any use of RYO cigarettes varied greatly between Malaysia (17%) and Thailand (58%). In both countries, any RYO use was associated with living in rural areas, older average age, lower level of education, male gender, not being in paid work, slightly lower consumption of cigarettes, higher social acceptability of smoking, and positive attitudes toward tobacco regulation. Among RYO users, exclusive use of RYO cigarettes (compared with mixed use) was associated with older age, female gender (relatively), thinking about the enjoyment of smoking, and not making a special effort to buy cheaper cigarettes if the price goes up. Finally, exclusive RYO smokers were less aware of health warnings (RYO tobacco carries no health warnings), but even so, knowledge of the health effects of tobacco was equivalent.

Fulltext Importance of hypertension and social isolation in causing sleep disruption in dementia

Eshkoor SA, Hamid TA, Nudin SS, Mun CY

Am J Alzheimers Dis Other Demen, 2014 Feb;29(1):61-6.
PMID: 24085252 DOI: 10.1177/1533317513505136

This study aimed to determine the effects of diabetes mellitus (DM), hypertension (HT), heart disease, social isolation, and sociodemographic factors on sleep in the elderly patients with dementia. Samples included 1210 noninstitutionalized, Malaysian elderly patients with dementia. The multiple logistic regression analysis was applied to estimate the risk of sleep disturbances among respondents. Approximately 41% of the patients experienced sleep problems. The results showed that age (odds ratio [OR] = 1.02), social isolation (OR = 1.33), and HT (OR = 1.53) significantly increased sleep disruption in respondents (P .05). It was concluded that age, social isolation, and HT increased sleep disruption but education and ethnic non-Malay reduced the risk of sleep problems. Moreover, HT was the most important variable to increase sleep disturbances in the elderly patients with dementia.

Factors Associated With Antidepressant Dosing in Asia: Findings From the Research on Asian Psychotropic Prescription Study

Rajaratnam K, Xiang YT, Tripathi A, Chiu HF, Si TM, Chee KY, et al.

J Clin Psychopharmacol, 2016 Dec;36(6):716-719.
PMID: 27753726

In this study, we sought to examine factors associated with dosing of antidepressants (ADs) in Asia. Based on reported data and clinical experience, we hypothesized that doses of ADs would be associated with demographic and clinical factors and would increase over time. This cross-sectional, pharmacoepidemiological study analyzed data collected within the Research Study on Asian Psychotropic Prescription Pattern for Antidepressants from 4164 participants in 10 Asian countries, using univariate and multivariate methods. The AD doses varied by twofold among countries (highest in PR China and RO Korea, lowest in Singapore and Indonesia), and averaged 124 (120-129) mg/d imipramine-equivalents. Average daily doses increased by 12% between 2004 and 2013. Doses were significantly higher among hospitalized patients and ranked by diagnosis: major depression > anxiety disorders > bipolar disorder, but were not associated with private/public or psychiatric/general-medical settings, nor with age, sex, or cotreatment with a mood stabilizer. In multivariate modeling, AD-dose remained significantly associated with major depressive disorder and being hospitalized. Doses of ADs have increased somewhat in Asia and were higher when used for major depression or anxiety disorders than for bipolar depression and for hospitalized psychiatric patients.

Fulltext Predictors of sexual risk behaviour among adolescents from welfare institutions in Malaysia: a cross sectional study

Farid ND, Rus SC, Dahlui M, Al-Sadat N, Aziz NA

BMC Public Health, 2014;14 Suppl 3(Suppl 3):S9.
PMID: 25437631 DOI: 10.1186/1471-2458-14-S3-S9

BACKGROUND: In welfare institutions, it is essential to address the health-related needs of adolescent populations who often engage in sexual activities. This study examines the association between individual and interpersonal factors concerning sexual risk behaviour (SRB) among adolescents in welfare institutions in Malaysia.
METHODS: Data were derived from a cross-sectional study of 1082 adolescents in 22 welfare institutions located across Peninsular Malaysia in 2009. Using supervised self-administered questionnaires, adolescents were asked to assess their self-esteem and to complete questions on pubertal onset, substance use, family structure, family connectedness, parental monitoring, and peer pressure. SRB was measured through scoring of five items: sexual initiation, age of sexual debut, number of sexual partners, condom use, and sex with high-risk partners. Multivariate logistic regression analysis was used to examine the various predictors of sexual risk behaviour.
RESULTS: The study showed that 55.1% (95%CI = 52.0-58.2) of the total sample was observed to practice sexual risk behaviours. Smoking was the strongest predictor of SRB among male adolescents (OR = 10.3, 95%CI = 1.25-83.9). Among females, high family connectedness (OR = 3.13, 95%CI = 1.64-5.95) seemed to predict the behaviour.
CONCLUSION: There were clear gender differences in predicting SRB. Thus, a gender-specific sexual and reproductive health intervention for institutionalised adolescents is recommended.

Old World screwworm fly, Chrysomya bezziana, occurs as two geographical races

Hall MJ, Edge W, Testa JM, Adams ZJ, Ready PD

Med Vet Entomol, 2001 Dec;15(4):393-402.
PMID: 11776458

A morphological and molecular analysis was undertaken with the objective of identifying markers for geographical populations of Old World screwworm flies, Chrysomya bezziana Villeneuve (Diptera: Calliphoridae). The morphological analysis involved 192 adult flies from 14 countries, and the molecular analysis involved 45 larvae or adults from 14 populations in 11 countries. Principal components and cluster analysis of 10 morphological characters indicated that flies from Papua New Guinea (PNG) were a distinct group and most similar to flies from nearby Asian islands (Java, Sabah). There was poor resolution of other geographical regions, but some support for clustering of flies from Africa or India. Cladistic analysis of mitochondrial DNA sequences gave strong support for recognizing two races of Old World screwworm, one from sub-Saharan Africa and the other from the Gulf region and Asia. This latter race could be further divided into two lineages, i.e. one from mainland Asia (from Iraq to the Malay Peninsula) and the other from two islands of PNG.

PMID: 34882716 DOI: 10.1371/journal.pone.0260675

Type 2 diabetes mellitus (T2DM) is increasingly known as a risk factor of hepatocellular carcinoma (HCC). In this study, we determined the risk factors associated with HCC in T2DM patients. This was a matched case-control study conducted at two hepatobiliary referral centres in a developing country. Patients' sociodemographic, clinical, and biochemical characteristics between 1 January 2012 and 30 June 2018 were extracted from the electronic medical records and analysed using multivariate logistic regression analysis. A total of 212 case-control pairs were included. Significant risk factors included Chinese and Malay ethnicities that interacted with viral hepatitis (adjusted odds ratio [AOR] = 11.77, 95% confidence interval [CI]: 1.39-99.79) and (AOR = 37.94, 95% CI: 3.92-367.61) respectively, weight loss (AOR = 5.28, 95% CI: 2.29-12.19), abdominal pain/ discomfort (AOR = 6.73, 95% CI: 3.34-13.34), alcohol (AOR = 4.08, 95% CI: 1.81-9.22), fatty liver (AOR = 3.29, 95% CI: 1.40-7.76), low platelet (AOR = 4.03, 95% CI:1.90-8.55), raised alanine transaminase (AOR = 2.11, 95% CI: 1.16-3.86). and alkaline phosphatase (ALP) levels (AOR = 2.17, 95% CI: 1.17-4.00). Statins reduced the risk of HCC by 63% (AOR = 0.37, 95% CI: 0.21-0.65). The identification of these factors aids the risk stratification for HCC among T2DM patients for early detection and decision-making in patient management in the primary care setting.

Mohd Ashri MH, Abu Saad H, Adznam SNΆ

Nutrients, 2021 Jun 29;13(7).
PMID: 34210072 DOI: 10.3390/nu13072248

The use of dietary supplements is prevalent among many groups worldwide. However, few studies have examined their use among government employees. The aim of this cross-sectional study was to determine the association among sociodemographic characteristics, body weight status, and energy intake with dietary supplement use among government employees in Putrajaya, Malaysia. Simple random sampling was used to select a sample of 460 government employees from six ministries in Putrajaya, Malaysia. The data used in this study were collected through anthropometric measurements (height, weight, % body fat, waist and hip circumferences), a self-administered questionnaire (sociodemographic characteristics and dietary supplements use), and an interviewer-administered questionnaire (24-hour dietary recall; fruit and vegetable intake). The results indicated that the prevalence of dietary supplement use was 55.4%, with vitamin C (38.4%) being the most popular type of dietary supplement. Health issues (80.8%) were the most common reason for usage, internet (59.2%) was the main source of information, and pharmacies (71.8%) were the most indicated places to purchase dietary supplements. A multivariate analysis showed that participants who were female, married, had better monthly income, lived within a smaller household size, had a normal body mass index, classified as having unhealthily high body fat percentage, did not skip breakfast, and consumed at least five servings of fruits and vegetables per day were significantly more likely to use dietary supplements. In conclusion, health-conscious groups were more prone to consume dietary supplements, and due to the high prevalence of dietary supplement use, dissemination of accurate scientific information regarding dietary supplements is highly recommended among government employees.

Chan MTV, Wang CY, Seet E, Tam S, Lai HY, Chew EFF, et al.

JAMA, 2019 May 14;321(18):1788-1798.
PMID: 31087023 DOI: 10.1001/jama.2019.4783

IMPORTANCE: Unrecognized obstructive sleep apnea increases cardiovascular risks in the general population, but whether obstructive sleep apnea poses a similar risk in the perioperative period remains uncertain.
OBJECTIVES: To determine the association between obstructive sleep apnea and 30-day risk of cardiovascular complications after major noncardiac surgery.
DESIGN, SETTING, AND PARTICIPANTS: Prospective cohort study involving adult at-risk patients without prior diagnosis of sleep apnea and undergoing major noncardiac surgery from 8 hospitals in 5 countries between January 2012 and July 2017, with follow-up until August 2017. Postoperative monitoring included nocturnal pulse oximetry and measurement of cardiac troponin concentrations.
EXPOSURES: Obstructive sleep apnea was classified as mild (respiratory event index [REI] 5-14.9 events/h), moderate (REI 15-30), and severe (REI >30), based on preoperative portable sleep monitoring.
MAIN OUTCOMES AND MEASURES: The primary outcome was a composite of myocardial injury, cardiac death, heart failure, thromboembolism, atrial fibrillation, and stroke within 30 days of surgery. Proportional-hazards analysis was used to determine the association between obstructive sleep apnea and postoperative cardiovascular complications.
RESULTS: Among a total of 1364 patients recruited for the study, 1218 patients (mean age, 67 [SD, 9] years; 40.2% women) were included in the analyses. At 30 days after surgery, rates of the primary outcome were 30.1% (41/136) for patients with severe OSA, 22.1% (52/235) for patients with moderate OSA, 19.0% (86/452) for patients with mild OSA, and 14.2% (56/395) for patients with no OSA. OSA was associated with higher risk for the primary outcome (adjusted hazard ratio [HR], 1.49 [95% CI, 1.19-2.01]; P = .01); however, the association was significant only among patients with severe OSA (adjusted HR, 2.23 [95% CI, 1.49-3.34]; P = .001) and not among those with moderate OSA (adjusted HR, 1.47 [95% CI, 0.98-2.09]; P = .07) or mild OSA (adjusted HR, 1.36 [95% CI, 0.97-1.91]; P = .08) (P = .01 for interaction). The mean cumulative duration of oxyhemoglobin desaturation less than 80% during the first 3 postoperative nights in patients with cardiovascular complications (23.1 [95% CI, 15.5-27.7] minutes) was longer than in those without (10.2 [95% CI, 7.8-10.9] minutes) (P

Role of Individual, Family, and Peers in Sexual Initiation Among Late Adolescents Attending Institutions of Higher Learning in Malaysia

Abdul Samad S, Hairi NN, Ismail M

Asia Pac J Public Health, 2016 05;28(4):313-24.
PMID: 27122624 DOI: 10.1177/1010539516645158

This cross-sectional study aimed to determine the prevalence and the factors associated with sexual initiation among the late adolescents in 6 institutions of higher learning in Malaysia. A total of 1572 students completed self-administered questionnaires between April and September 2013. Hierarchical multivariate logistic regression analyses stratified by gender were employed to identify the correlates of sexual initiation. The analyses were further adjusted by sampling weights. The overall prevalence of sexual initiation was 9.8% (95% confidence interval [CI] = 8.3-11.6), 18.1% (95% CI = 15.1-21.5) among males, and 4.1% (95% CI = 2.9-5.9) among females. The risk factors identified in this study supported the influence of the individual, family, and peer factors in the social-ecological model on adolescents' behaviors. The findings suggest the need for risk-reduction strategies aimed at the individual, family, and peer levels as well as the importance of gender-specific focus in assuring better outcomes.

Parental smoking status, stress, anxiety, and depression are associated with susceptibility to smoking among non-smoking school adolescents in Malaysia

Lim KH, Chong Z, Khoo YY, Kaur J

Asia Pac J Public Health, 2014 Sep;26(5 Suppl):81S-90S.
PMID: 25038194 DOI: 10.1177/1010539514542426

Susceptibility to smoking is a reliable predictor of smoking initiation. This article describes its prevalence and associated factors among Malaysian school adolescents. Data were obtained from the Global School-Based Student Health Survey (GSHS) 2012, a nationwide representative sample of school adolescents. The overall prevalence of susceptibility to smoking was 6.0% and significantly higher among males (9.5%) compared with females (3.6%). Multivariable analyses revealed that males (adjusted odds ratio [aOR] 3.34, 95% confidence interval [CI] 2.70-4.18) and school adolescents of indigenous Sabahan or Sarawakian descents (aOR 1.62, 95%CI 1.21-2.18) were significantly more likely to be susceptible to smoking. Susceptible school adolescents had a slightly higher likelihood to have symptoms of stress (aOR 1.31, 95% CI 1.02-1.70), anxiety (aOR 1.19, 95% CI 1.01-1.40), depression (aOR 1.56, 95% CI 1.25-1.96), including those whose one or both parents/guardians were smokers (aOR 1.48, 95% CI 1.21-1.82; aOR 2.33, 95% CI 1.22-4.44, respectively). The findings from this study point out the need for proactive measures to reduce smoking initiation among Malaysian adolescents with particular attention toward factors associated with susceptibility to smoking.

Tee GH, Kaur G

Asia Pac J Public Health, 2014 Sep;26(5 Suppl):70S-80S.
PMID: 24965781 DOI: 10.1177/1010539514540468

Cigarette smoking in adolescent is a significant public health problem, leading to the risk of addiction, morbidity, and mortality in the long term. This study determined the prevalence and correlates of current smoking among adolescent school children. A nationwide school-based survey among 25 507 students between Forms 1 to 5 (aged 12-17) was conducted using a 2-stage cluster sampling design. The prevalence of current smoking was 11.5%. Multivariable logistic regression analysis revealed that current smoking was significantly associated with males (adjusted odds ratio [aOR] = 3.25; 95% confidence interval [CI] = 1.87, 4.98), current drinking (aOR = 2.34; 95% CI = 1.46, 3.74), drug used (aOR = 2.97; 95% CI = 1.24, 7.11), and being bullied (aOR = 1.41; 95% CI = 1.00, 1.98) at least once in the past 12 months. Smoking is associated with several behaviors that pose risks to adolescents, such as social issues and smoking-related health problems. Thus, early and integrated prevention programs that address multiple risk behaviors simultaneously are required.

Frail Elders in an Urban District Setting in Malaysia: Multidimensional Frailty and Its Correlates

Sathasivam J, Kamaruzzaman SB, Hairi F, Ng CW, Chinna K

Asia Pac J Public Health, 2015 Nov;27(8 Suppl):52S-61S.
PMID: 25902935 DOI: 10.1177/1010539515583332

In the past decade, the population in Malaysia has been rapidly ageing. This poses new challenges and issues that threaten the ability of the elderly to independently age in place. A multistage cross-sectional study on 789 community-dwelling elderly individuals aged 60 years and above was conducted in an urban district in Malaysia to assess the geriatric syndrome of frailty. Using a multidimensional frailty index, we detected 67.7% prefrail and 5.7% frail elders. Cognitive status was a significant correlate for frailty status among the respondents as well as those who perceived their health status as very poor or quite poor; but self-rated health was no longer significant when controlled for sociodemographic variables. Lower-body weakness and history of falls were associated with increasing frailty levels, and this association persisted in the multivariate model. This study offers support that physical disability, falls, and cognition are important determinants for frailty. This initial work on frailty among urban elders in Malaysia provides important correlations and identifies potential risk factors that can form the basis of information for targeted preventive measures for this vulnerable group in their prefrail state.

Prevalence and correlates of depression among adolescents in Malaysia

Kaur J, Cheong SM, Mahadir Naidu B, Kaur G, Manickam MA, Mat Noor M, et al.

Asia Pac J Public Health, 2014 Sep;26(5 Suppl):53S-62S.
PMID: 25070697 DOI: 10.1177/1010539514544356

Depression among adolescents has been recognized as a major public health issue. The objective of this study was to determine the prevalence and correlates of depression among school-going adolescents in Malaysia. Data from the Malaysia Global School-based Health Survey (GSHS) 2012 were analyzed with additional data from the validated DASS21 (Depression, Anxiety, and Stress) questionnaire. The study revealed that 17.7% of respondents had depressive symptoms. Multivariate analysis further showed that feeling lonely (adjusted odds ratio [aOR] = 2.99; 95% CI = 2.57-3.47), Indian ethnicity (aOR = 2.00; 95% CI = 1.63-2.44), using drugs (aOR = 1.85; 95% CI = 1.21-2.82), and being bullied (aOR = 1.79; 95% CI = 1.60-1.99) were significantly associated with depressive symptoms. Lack of parental supervision, alcohol use, and tobacco use were also significant risk factors. Addressing depressive symptoms among adolescents may have implications for managing their risks of being bullied and substance use. This study also highlights the need to further investigate depressive symptoms among adolescents of Indian ethnicity.

Zulkifli SN, Low WY

Asia Pac J Public Health, 2000;12 Suppl:S58-66.
PMID: 11338741

A survey was conducted to assess student's sexual knowledge and attitudes using a questionnaire based on the Sex Knowledge and Attitude Test (SKAT-II) to compare medical and nursing students with students (non-medical/nursing) who registered for a sexual health course. 85 Sexual Health, 115 medical and 81 nursing students voluntarily participated in the survey. This study showed that all the student groups showed relatively low scores in knowledge. Furthermore, average knowledge scores differed significantly between the three student groups with medical students scoring highest and nursing students lowest. Besides student groups, several other factors were found to be significantly associated with Knowledge score namely, race, religion, age, perception of the importance of religion and the extent to which religious beliefs influence sexual attitudes. Furthermore, multivariate statistical analyses showed that among these factors, student group, race/religion and religious importance were significant predictors of sexual knowledge. Specifically, being a medical student was associated with higher scores relative to a non-medical student, being a Malay student was independently associated with a lower average score compared to other races, and perceiving religion as extremely important was associated with a lower score.

PMID: 19124319 DOI: 10.1177/1010539508317130

Osteoporosis is a silent disease and becomes clinically significant in the presence of fragility fracture. Identifying risk factors that are associated with osteoporosis in the community is important in reducing the incidence of fragility fracture. The aim of this study is to identify risk factors associated with fragility fracture in the Seremban District of Malaysia. This is a population comparison study between orthopedic ward patients and outpatients attending a community health clinic for 6 months. Epidemiological data and the possible risk factors for osteoporosis were collected by direct interview. This study demonstrates that advancing age, low body weight, smoking, lack of regular exercise, low consumption of calcium containing foods, and using bone depleting drugs (steroids, thyroid hormone, and frusemides) are major risk factors for fragility fracture. Most of these risk factors are modifiable through effective lifestyle intervention.

Variation in the prevalence, awareness, and control of diabetes in a multiethnic population: a nationwide population study in Malaysia

Rampal S, Rampal L, Rahmat R, Zain AM, Yap YG, Mohamed M, et al.

Asia Pac J Public Health, 2010 Apr;22(2):194-202.
PMID: 19443875 DOI: 10.1177/1010539509334816

The purpose of this study was to determine the association between different ethnic groups and the prevalence, awareness, and control of diabetes in Malaysia. A population-based cross-sectional study using multistage sampling was conducted in Malaysia. Diabetes is defined as having a fasting blood glucose > or =7 mmol/L or a self-reported diabetic on treatment. Among the 7683 respondents aged > or =30 years, the prevalence of diabetes mellitus was 15.2% (95% CI = 14.1, 16.4). Multivariate analysis showed that compared with Malays, Chinese had lower odds (adjusted odds ratio [aOR] 0.71; 95% CI = 0.56, 0.91) and Indians had higher odds of having diabetes (aOR 1.54; 95% CI = 1.20, 1.98). The odds of diabetes increased with age, family history of diabetes, body mass index, and lower education levels. Among those with diabetes mellitus, 45.0% were aware and 42.7% were under treatment. Among treated diabetics, 25.1% had their fasting blood sugar under control. There is a significant association between prevalence of diabetes and different ethnic groups.

Bone-related complications of transfusion-dependent beta thalassemia among children and adolescents

Mirhosseini NZ, Shahar S, Ghayour-Mobarhan M, Banihashem A, Kamaruddin NA, Hatef MR, et al.

PMID: 23475127 DOI: 10.1007/s00774-013-0433-1

Thalassemia and the blood transfusion complications associated with it predispose children to poor bone health. This study was conducted to determine the prevalence of bone-related abnormalities and identify the bone health predictors within this population. One hundred and forty transfusion-dependent beta thalassemic subjects 8-18 years old in Mashhad, Iran, participated in this cross-sectional study. Anthropometric measures, dietary intake, bone-related biomarkers and bone densitometry, were assessed. The incidence of underweight and short stature was 33.6 and 41.4 %, respectively, which were indicators of malnutrition among thalassemic subjects in this study. Low bone density was detected in the lumbar spine and femoral region in 82 and 52 % of subjects, respectively. Hypocalcemia and hypophosphatemia were seen in 22 and 18.2 %, whilst vitamin D deficiency was present in more than 85 % of thalassemic children and adolescents. The relationships between weight, height and other anthropometric indices, serum calcium and bone markers, intake of macronutrients, zinc and vitamin E with bone mineral density (BMD) and bone mineral content (BMC) in the lumbar spine and femoral area were positively related, indicating that better nutritional status were associated with higher BMD and BMC values. Puberty, gender and serum osteocalcin were negative predictors for BMD and BMC values, whereas age, weight and height were the positive predictors. High incidence of low bone density and deficit in other aspects of bone health among thalassemia patients makes routine bone health assessment necessary for this vulnerable group. Considering influencing factors, dietary counseling and preventive supplementation therapy for this high risk group of children and adolescents may be necessary, although this should be assessed by intervention studies.

Fulltext Seroprevalence of Sparganosis in Rural Communities of Northern Tanzania

Kavana N, Sonaimuthu P, Kasanga C, Kassuku A, Al-Mekhlafi HM, Fong MY, et al.

Am J Trop Med Hyg, 2016 Oct 05;95(4):874-876.
PMID: 27481059 DOI: 10.4269/ajtmh.16-0211

In this study, the seroprevalence of sparganosis and its relationship with sociodemographic factors in northern Tanzania have been assessed. A total of 216 serum samples from two rural districts, Monduli and Babati, were tested for sparganosis using an enzyme-linked immunosorbent assay. The seroprevalence of anti-sparganum IgG antibodies was 62.5% (95% confidence interval [CI] = 56.1-68.9) in all age groups. There were significant associations between district (relative risk [RR] = 1.95, 95% CI = 1.42-2.69), education (RR = 1.40, 95% CI = 1.15-1.70), and pet ownership with seropositivity (RR = 1.48, 95% CI = 1.02-2.16) based on univariate analysis. However, only the district was significantly associated with seropositivity (odds ratio = 4.20, 95% CI = 1.89-9.32) in binary logistic regression analysis. Providing health education to people residing in sparganosis-endemic areas is likely to improve the efficacy of preventative measures and reduce human disease burden.
