INTRODUCTION: Malaysia participated in the second phase of the Global Adult Tobacco Survey (GATS) in 2011. GATS, a new component of the Global Tobacco Surveillance System, is a nationally representative household survey of adults 15 years old or above. The objectives of GATS Malaysia were to (i) systematically monitor tobacco use among adults and track key indicators of tobacco control and (ii) track the implementation of some of the Framework Convention of Tobacco Control (FCTC)-recommended demand related policies.
METHODS: GATS Malaysia 2011 was a nationwide cross-sectional survey using multistage stratified sampling to select 5112 nationally representative households. One individual aged 15 years or older was randomly chosen from each selected household and interviewed using handheld device. GATS Core Questionnaire with optional questions was pre-tested and uploaded into handheld devices after repeated quality control processes. Data collectors were trained through a centralized training. Manuals and picture book were prepared to aid in the training of data collectors and during data collection. Field-level data were aggregated on a daily basis and analysed twice a week. Quality controls were instituted to ensure collection of high quality data. Sample weighting and analysis were conducted with the assistance of researchers from the Centers for Disease Control and Prevention, Atlanta, USA.
RESULTS: GATS Malaysia received a total response rate of 85.3% from 5112 adults surveyed. Majority of the respondents were 25-44 years old and Malays.
CONCLUSIONS: The robust methodology used in the GATS Malaysia provides national estimates for tobacco used classified by socio-demographic characteristics and reliable data on various dimensions of tobacco control.

Introduction Elderly are often associated with multiple social and health problems. Family members are important in helping them doing their daily activities. For elderly diabetics, family support has a role in diabetes management and glucose control. The aim of this study is to explore the perceptions of elderly diabetics regarding the role of family support on their glucose control.
Methods This qualitative technique was a part of the study on glucose control and its associated factors among elderly diabetics. It was conducted from February until May 2009 in Kulim. Ten respondents were purposively sampled based on their glucose control. HbA1c 6.5% or less was considered as good glucose control. In depth interview, using semi-structured interview guide was used in this study. The conversation had been taped, transcribed to verbatim and analyzed manually using thematic analysis.
Results All ten respondents perceived that family support did not play a role on their glucose control. They believed that self-awareness and self-determination were important to control the glucose level. Those with good glucose control practiced healthy diet, and not affected by food prepared by their family members compared to those with poor glucose control. However, both groups claimed that, they did not receive much advice from their family members and no special food was prepared for them. Conclusions Elderly diabetics should be motivated on self-determination and focusing on good glucose control. Health education should be given to patients and their family members to increase their diabetes knowledge especially on useful advice and proper food preparation. It could motivate the elderly diabetics to control their glucose level.
Introduction Food labeling regulation has been implemented to enable consumers, including those with chronic diseases to make healthy informed choices before purchasing pre-packaged foods. The purpose of this study is to determine the prevalence of obese adults in Malaysia who practice reading food labels. It explored types of labels read and understanding of the information.
Methods Findings presented in this study were captured from the secondary analysis of National Health and Morbidity Survey’s (NHMS, 2006) food label study which focused only on obese adults (BMI > 30 kg/m2) aged 18 and above. This nation-wide cross sectional study was conducted from April to August 2006 using an interview-based questionnaire. Complex data analysis was done using Stata version 12.0.
Results There were 4565 obese respondents with the mean age of 33 ± 9.7 (18-60 years old). About 54.7% completed high-school and 9.9% were higher degree
holders. Prevalence of obese adults who claimed to read label was 80.5% (95%CI: 79.3, 81.6). Findings showed significant results in reading and understanding labels among all age group categories, Malay, Indian and other Bumiputras, all education categories and married respondents. Expiry date was the highest percentage being read (74.5%), followed by fat content (15.3%), vitamin (11.8%) and carbohydrate (10.9%).
Conclusions The obese population in Malaysia claimed to read and understand the food label but did not focus on specific macronutrients related to their health
condition. Findings can be used to implement effective education programmes targeting the relevant groups to instill an awareness to read, understand and use the label information as one of the means in combating obesity.

Belaga District, in the heart of Borneo, is probably the most remote district in Sarawak. Although Belaga town is now accessible by land (50% are timber camp unsealed road) from Bintulu, the journey takes 5 hours and transport cost is high. Accessibility to Belaga by river is also subject to weather conditions and the town often gets cut off during the dry season and also during the wet season. All these pose immense challenges to the delivery of health care services to the people of Belaga and greatly reduce their accessibility to even basic health services. Access to specialist services is even more challenging as it is only available in Sibu and Bintulu; and visiting clinics in Belaga are infrequent due to the shortage of specialists and difficult transport. (Copied from article).
To date, there has been no systematic research that investigates the rural community awareness and attitudes towards pandemic influenza H1N1 and its prevention measures in the context of Sarawak. There is also no systematic study about whether the initiatives to educate the public undertaken by the government and other agencies have empowered the rural communities to practice an effective self-care within the context of community, that assist to curb the potential spread of this disease. Our research aims to address these limitations. In this paper, we report a survey finding about the awareness and attitudes of the Serian community with regard to this area of research interest. We also investigate the relevant sources of information that the community relies on in understanding about the influenza and how it can spread. Overall, the outcomes of the survey reveal that a majority of our respondents has a relatively low level of knowledge and awareness particularly about the characteristics of the illness and how H1N1 virus can transmit. With regard to prevention measures, a majority of them reported good understanding and awareness about the effective self-care practices that can help to curb the potential spread of the influenza. The top five sources to obtain information about the influenza were: information from family, relatives, friends or neighbours; radio; TV; newspapers; and government health talk seminar or campaigns. The research outcomes can offer pragmatic contributions that can benefit the health campaigners and policy makers.
The increase in car usage due to economic prosperity has led to increase in occupant injuries. One way to reduce the injuries encountered by road accident victims is by implementing the rear seatbelt (RSB) law. Rear seatbelt wearing has been proven to save lives. In Malaysia, the implementation of the restraint system for front occupant has started in the 70's. However, the rear seatbelt enforcement law only came in 2009, after six months of an advocacy program. Prior to the introduction of the rear seatbelt law, rear seatbelt wearing rate was rather low, started to increase gradually during the advocacy period and jumped to the highest level after two month of the enforcement. This paper attempts to assess the effectiveness of the rear seatbelt intervention in reducing injuries among passenger car occupants in Malaysia using the generalized linear model (GLM). In GLM procedure, the dependent variable is the number of people from passenger vehicles that sustained severe and slight injuries, for the study period. The study period selected covers six months before implementation, six months during advocacy program, and six months after the law is implemented. The independent variables considered are enforcement and balik kampung activities (both are dummy variables) and time effect. Our results suggest that RSB intervention (p-value= 0.0001) had significantly reduced the number of people sustained serious and slight injuries by about 20%. The implementation of change in the RSB law has benefited not only in reducing the number of injuries but also result to great impact to the health outcomes.
Introduction In Malaysia although mortality rate among women of reproductive ages has
reduced over the years, the reduction has been stagnant for the past ten years.
In order to achieve the 5th Millennium Development Goal, several measures
need to be taken including a proper implementation of pre-pregnancy
services in this country. This study explores the awareness, intention and
usage of pre-pregnancy care (PPC) services and its determinant among
women of reproductive ages in Kedah, Malaysia.
Methods This is a qualitative study, which consisted of a focus group discussion
(FGD) among women in the ages of 18 to 45 years old from all ethnic groups
who attended four government clinics in the state of Kedah. The mothers
were chosen through purposive sampling from twelve districts that were
selected through a multistage random sampling. A semi-structured
questionnaire was utilized during the FGD. The results from the FGD were
recorded verbatim and thematic analysis was finalized once saturation of
information from respondents was achieved.
Results These are two themes was identified, namely personal reasons and reasons of
service and there are several subthemes under two main themes. Under the
Personal reason themes, the subthemes including awareness and intention to
used the services, knowledge, perception, social support and history of
medical illness. While under pre-pregnancy care services themes, the
subthemes including the promotion of the services, the communication
relationship with the health staff, the waiting time and also the accessibility
of the service.
Conclusions As a conclusion, there is still part of society who was unaware of prepregnancy
services and its importance in reducing maternal mortality rate as
well as producing good pregnancy outcome. Information and knowledge on
pre-pregnancy care services should be disseminated among community
members through various means including roadshows and pre wedding
workshops.

Introduction The extensive and intensive use of pesticides in agricultural practices has exposed farmers to various hazards resulting in varying degrees of health
outcomes.
Methods We conducted a cross-sectional study among paddy farmers in Sabak Bernam district, Malaysia. The objective of this study was to gather baseline information on chlorpyrifos blood level and its relationship with pesticides exposure symptoms.
Results We detected chlorpyrifos in farmers’ blood in 7 percent of the respondents, with mean 7.29 nanogram per millilitre blood (sd 5.84 nanogram per millilitre). The percentage of farmers who experienced at least one pesticide exposure symptoms was 75 percent. However, we found no significant association between chlorpyrifos blood level and its exposure symptoms. The farmers had low scores on safe practice of pesticide use even though they have high marks on knowledge and attitude. We found no significant association between the scores on knowledge, attitude and practice on pesticide use and the chlorpyrifos blood level.
Conclusions The presence of pesticide exposure symptoms proved that most of the farmers were exposed to hazardous effects of pesticides. Specific trainings on safe use and handling of pesticides should be given on regular basis to these farmers to ensure they are protected from hazardous effects of pesticides exposure.
Dengue is a disease propagated by vectors namely Aedes spp. mosquitoes. One of the effective approaches to control dengue is through integrated vector management and intervention programs. COMBI or Communication for Behavioral Impact is a strategic approach to control the Aedes population as well as dengue cases. This study was conducted at Taman Desa Kolej, Nilai, Negeri Sembilan, an suburban residential area to determine the effectiveness of COMBI, by using questionnaire and entomological survey as well as implementation of an intervention program. We carried out activities such as the establishment of COMBI promoter team, clean up events, talk shows with the residential community and distributed pamphlets containing information about dengue. Results indicated significant difference (p
Introduction: Congenital malformations (CM) comprise a wide range of abnormalities of body structure or function that are present at birth and are of prenatal origin. It has contributed to a significant proportion of infant morbidity and mortality. The aims of this study were to determine the extent and investigate the relationship between CM and its associated demographic variables.
Methods: Data was extracted from Ministry of Health (MOH) database compiled from the reports on Stillbirth & Under 5 Mortality from year 2013 to 2014.
Results Out of 9,827 child death, 2,840 (28.9%) were classified under CM as defined under ICD-10 classification. Majority of those with CMs died at neonatal stage (62.7%) and among mothers aged between 20 to 35 years old (67.3%). The mean age of mothers among CM children was 30.8±6.5 years old. Approximately 5.8%, 6.7% and 3.3 % of total CM were neural tube defects, heart defects and hydrops fetalis respectively. The prevalence of CM in males was 15% higher than females. The difference were evident between CM and age of death of children under 5 years old (p<0.001) as well as between CM and maternal age groups (p<0.001).
Conclusions: CM is responsible for 28.9% of total causes of child death with higher occurrence of malformation in males. A significantly higher risk of CMs among mother aged between 20 to 35 years old was observed. This emphasises the importance of raising awareness and the need to strengthen appropriate response for surveillance and prevention program of common CM in Malaysia.

Introduction The use of dietary supplements had risen over the years among chronic
disease patients with most of it were of patients' own initiative. This study
aimed to describe the supplements use, assess the knowledge and attitude
towards supplements and its interaction with prescribed medication, and
determine whether knowledge and attitude towards supplements could
influence treatment adherence in chronic disease patients.
Methods A cross-sectional study was conducted among chronic disease patients in
Universiti Kebangsaan Malaysia Medical Center, Kuala Lumpur from
September to November 2016 upon their written informed consent. This
study consists of a collection of validated instruments that measured the use
of dietary supplements and its reason; the knowledge and attitude on dietary
supplements and supplements-drug interaction and medication adherence.
Results A total number of 250 respondents were interviewed and 72.4% was found to
use supplements of own initiatives. Most of the respondents were using
supplements to maintain health (78.8%), prevent health problems (72.4%)
and improve overall health (63.2%). It was found that respondents'
knowledge on supplement-drug interactions were not at the satisfactory level.
The treatment adherence was found not to be associated with knowledge and
attitude towards supplements nor numbers of supplements use.
Conclusions Chronic disease patients mainly knew on the purpose of supplements for
health and wellness, but had less knowledge on supplement-drug interactions,
warranting patients' education on that particular field.
Introduction The health of newborns is inextricably linked to that of their mothers. Some
maternal factors can influence neonatal survival, particularly for low birth
weight babies who are more vulnerable to diseases than normal weight
babies. The aim of this study is to assess the impact of maternal factors on
neonatal mortality among low birth weight babies in Aceh Province,
Indonesia.
Methods Study design was unmatched case control. Data collected from 2010 to 2012
in 8 districts in Aceh province, Indonesia. Total sample was 500, divided into
250 LBW who died in neonatal period (case group) and 250 who did not die
in neonatal period (control group). There were 6 maternal variables analysed.
Results Three of six variables analysed were not associated with neonatal mortality
among LBW (P > 0.05); these were: maternal death, parity and education
level. The age of the mother had a significant association with neonatal
mortality among LBW (P < 0.05), but was not a determinant factor. The
maternal illness and birth interval were determinant factors of neonatal
mortality among LBW(P < 0.05); maternal illness (Adj OR= 2.6; 95 % CI:
1.68 - 4.0) and birth interval (Adj OR= 1.8; 95 % CI: 1.20 - 2.91).
Conclusions Maternal illness and birth interval were determinant factors of neonatal
mortality among LBW. Appropriate care throughout stages of pregnancy and
increasing women’s knowledge on high risk pregnancy are the key factors to
the decrease of the neonatal mortality related to the maternal factors.
Introduction: Validation of instruments is essential when assessing physical activity (PA). The aim of this study was to validate a Malay language version of the International Physical Activity Questionnaire (IPAQ-M) against Actical accelerometer and to determine its reliability and validity.
Methods: A total of 90 Malay adults aged 35-65 years old participating in The Malaysian Cohort project were recruited for this study. The IPAQ-M is comprised of 12 items, covering vigorous, moderate, walking, sitting and sleeping activities, and was administered on two occasions (Day 1 and Day 9) by interviewing the participants. Participants wore the Actical accelerometer for seven consecutive days between the two interview sessions. Results Validity tests showed that time spent in moderate-vigorous physical activity (MVPA) (min/wk) from IPAQ-M was significantly correlated with MVPA from accelerometer (rho=0.32, p<0.01). Time spent in vigorous activity (rho=0.44) and total activity (rho=0.36) from IPAQ-M were significantly correlated (p<0.01) with that measured by accelerometer, but no correlation was observed for sedentary behaviour. Reliability tests revealed significant correlations between the two interview sessions for all intensities of PA (rho=0.55 to 0.71, p<0.01). Bland-Altman plots showed that time spent in MVPA for IPAQ-M was significantly different from that measured by accelerometer (mean difference: 98.02 min/wk; 95% limits of agreement: -785.33 to 1317.83 min/wk; p<0.01). When classifying people into meeting PA recommendation, the agreement between the two instruments was fair (κ=0.22).
Conclusions The IPAQ-M has acceptable validity for MVPA, vigorous and total physical activity, and was reliable for assessing the physical activity of Malay adults.

Introduction The prevalence of non-communicable diseases (NCDs) in Malaysia shows a
rising trend that influences the society in many respects. Country specific
evidence is vital for effective intervention. The aims of this study were to
identify the role of gender and urbanisation status on NCDs prevalence and
its effect on health care demand, specifically doctor visits among elderly in
Malaysia. We focused on two of the highest occurrence NCDs in the country
– diabetes mellitus and hypertension.
Methods A total of 1,414 respondents aged 60 years and above were selected using a
multistage sampling for face-to-face interview. We started the analysis with
descriptive analysis of the prevalence, taking the effect of gender and
urbanisation status of residing area. We extended the study with parametric
analysis to find the effect of these health problems on the likelihood of doctor
visits as it reflects the equity for access and utilisation issues.
Results Results showed that there were no significant difference of prevalence by
gender and urbanisation for hypertension and diabetes mellitus. By utilising
probit model, we found that those with diabetes mellitus or hypertension,
controlling for other variables, were more likely to utilise doctor services.
Conclusion This result implies that the prevalence of NCDs may further increase demand
for health care, especially in the state with a high proportion of older age
groups.

Introduction Cervical cancer (CC) is the second most prevalent female cancer in Malaysia. Almost 70% of its’ causal factors are attributable to oncogenic human papillomavirus (HPV) types 16, 18 and other risk factors. HPV genotypes distributions are also noted to differ by geographical area.
Methods This was cross sectional study conducted in 2007, to determine the influencing factors of HPV positivity and prevalence of HPV infections among patients with cervical cancer in Universiti Kebangsaan Malaysia Medical Centre (UKMMC). Patients’ paraffin-embedded cervical tissues kept in the Pathology Department from 1999 to 2007 were randomly selected. A total of 81 medical records with complete information were chosen as samples and patients were contacted for consent. Tissue samples were further derived for PCR DNA for HPV genotyping. Analyses included descriptive statistics; bivariate χ2 test and correlation were used to determine relationship between factors and HPV positivity. Significance level of less than 0.05 was taken as statistically significant.
Results Mean age of cancer diagnosis was at 52 ± 12.2 years. Women of Chinese ethnicity was the highest ethnicity to be HPV positive at 65.4% and squamous cell carcinoma was more commonly found (59.3%) compared with other types of cancers. The prevalence of HPV positivity was 92.6% with type 16 being the most common (74.1%), followed by type 33 (30.9%) and 18 (22.2%). Multiple HPV infections were a common finding at 54.3%. Factors thought to influence positivity i.e. age of intercourse, number of sexual partners, number of parity, smoking status of patients and their partners, oral contraceptive usage, presence of chronic illnesses and cancer stage were not significantly associated with HPV positivity. Increased CC severity level was not associated with increased number of HPV infections (Pearson correlation 0.58; p =0.607).
Conclusions High HPV positivity at 92.6% was found among ICC patients. Factors thought to influence HPV positivity were not significant. The top three HPV genotypes were type 16 followed by type 33 and 18. However, local women HPV serotypes findings need to be replicated in a larger population sample.
Introduction Pneumococcal disease causes considerable morbidity and mortality,
including among adults. Adult pneumococcal vaccines help to prevent these
burdens, yet, they are underutilized. Our objective is to systematically collect
and summarize the available evidence on the potential factors that lead to
pneumococcal vaccination acceptance among of adult community.
Methods A systematic literature search was conducted involving studies published
from January 1999 to December 2015. The studies were identified by
searching electronic resources (PubMed/MEDLINE and Pro Quest database)
and manual searches of references. The keywords “vaccine/ immunization”,
“uptake/ coverage”, “determinant/ factor”, and “Streptococcus pneumoniae/
pneumococcus/ pneumococcal” were used. Final studies result and data were
reviewed by two independent authors. Disagreement was resolved through
discussion and consensus.
Results A total of 171 studies were identified, only 17 studies were included in final
discussion with 10 domains identified in the paper. 7 studies (41%) had
reported that the provider domain, patients’ perception and
socio-demographic factor have had the most effect on the pneumococcal
vaccination acceptance rate. In addition, only 18% (3) of reviewed papers had
highlighted that socio-economic was a factor influenced the pneumococcal
vaccination acceptance while 24% (4 studies) were attributed to the comorbid
domains.
Conclusions Healthcare provider and patients’ perception about pneumococcal vaccination
for adult population are significant domains which influence the acceptance
towards vaccination. Strong recommendations from healthcare provider for
pneumococcal vaccination would be an important step to increase vaccination
acceptance among the population.
Introduction Physical activity reduces risk of non-communicable diseases. Physical
activity prevalence is low due to barriers to physical activity. This study was
conducted to translate the Barrier to Physical Activity (BPA) questionnaire
into Malay and assess the reliability and validity of the translated version
among nurses.
Methods The Malay version of BPA was developed after translating the English
version of BPA through back to back translation process. The Malay BPA
was distributed among 306 volunteered nurses from 5 government hospitals
in Selangor state. Factor analysis, Cronbach’s alpha test and test – retest
reliability was conducted to determine psychometric properties of BPA.
Results Chronbach’s alpha coefficient was 0.79 for perceived benefits items and 0.51
for perceived barrier items (overall was 0.73). The ICC was 0.88 (95% CI:
0.78-0.93) for test-retest testing after 7 days. Two factors components were
yielded through exploratory factor analysis with eigenvalues of 3.9 and 2.0
respectively. Both the factors accounts for 31.4 % of the variance. Factor 1
included 14 items and explained 19.9% of the variance. Factor 2 consisted of
5 items and explained 11.5% of variance. CFA yielded two factor structures
with acceptable goodness of fit indices [x2/df = 23.99; GFI = 0.82, SRMR =
0.09; PNFI = 0.49 and RMSEA = 0.10 (90%CI = 0.09-0.11)].
Conclusions The Malay version of BPA had demonstrated satisfactory level of validity
and reliability to assess barriers to physical activity. Therefore, this
questionnaire is valid in assessing barriers to physical activity among
working population.
The aim of this study was to determine the profile of patients referred to a specialist oral medicine and oral pathology unit in Kuala Lumpur by reviewing clinical dental records received in Oral Pathology Diagnostic Service (OPDS) in Faculty of Dentistry, UKM from 2001 until 2010. A total of 547 archival biopsy clinical dental records were reviewed and analysed using SPSS version 17.0. Oral and maxillofacial diseases were frequently seen in female (1.3:1), young adults (30.0%) of Malay ethnicity (64.6%). Most of the acquired specimens were from dental specialists (n=451, 84.8%), particularly from oral and maxillofacial surgeons (OMFS) (n=349, 63.8%) compared to general dental practitioners (GDPs) (n=81, 14.8%). Almost all of the biopsy specimens were of soft tissue origin (n=462, 84.4%), derived from lining mucosa (n=197, 36.0%) and were biopsied excisionally (n=325, 59.4%) more often than by incisional biopsy (n=207, 37.8%). A large proportion of the oral and maxillofacial diseases were of reactive (n=188, 34.4%) and inflammatory (n=121, 22.1%) cause. Tumours are mainly benign (n=69, 12.6%) with only small cases are malignant (n=34, 6.2%). The most common histological diagnoses were accounted by mucocele (n=56, 10.2%), pyogenic granuloma (n=47, 8.6%), fibroepithelial polyp (n=38, 6.9%), radicular cyst (n=33, 6.0%) and periapical granuloma (n=29, 5.3%). This study characterizes the clinical profile of patients seen in our oral medicine and oral pathology unit. Present findings can be used as a reference to the clinicians and pathologists in effective patient management and organization in the future.
Introduction Anxiety and depression were known to bring detrimental outcome in patients
with ischemic heart disease (IHD). Notwithstanding their high prevalence
and catastrophic impact, anxiety and depression were unrecognized and
untreated. The aim of this study was to determine the prevalence of anxiety
and depression among IHD patients and the association of this condition with
clinical and selected demographic factors.
Methods This was a cross-sectional study on 100 IHD patients admitted to medical
ward in UKMMC. Patients diagnosed to have IHD were randomly assessed
using Hospital Anxiety and Depression Scale (HADS) and Perceived Social
Support (PSS) Questionnaire. Socio-demographic data were obtained by
direct interview. Fifteen percent of IHD patients in this sample were noted to
have anxiety, fourteen percent noted to have depression while thirty two
percent was noted to have both anxiety and depression. Patients’ age group
and the duration of illness were found to have significant association with
anxiety. Socio-demographic data were obtained by direct interview.
Results Fifteen percent of IHD patients in this sample were noted to have anxiety,
fourteen percent noted to have depression while thirty two percent was noted
to have both anxiety and depression. Patients’ age group and the duration of
illness were found to have significant association with anxiety. The other
clinical and selected demographic factors such as gender, race, marital status,
education level, occupation, co-existing medical illness and social support
were not found to be significantly associated with anxiety or depression
among the IHD patients.
Conclusions In conclusion, proper assessment of anxiety and depression in IHD patients,
with special attention to patients’ age and duration of illness should be
carried out routinely to help avert detrimental consequences.
Overweight and obesity are a serious public health problem globally. Healthcare workers in some countries have been reported to be having a high prevalence of being overweight despite them being well informed of the aetiology and risks of excessive body weight. However, the problem of being overweight and obese among Malaysian healthcare workers is still poorly understood. The aim of this study is to assess the prevalence and factors associated with overweight and obesity among healthcare workers in Pejabat Kesihatan Daerah (PKD) Melaka Tengah.
