Alcohol Use and Its Relation with Demographic, Environmental, and Psychological Factors among Adolescents in Nabawan, Sabah.

Background: Adolescence is an essential stage of a child's development, transitioning them into adulthood. During this time, they are vulnerable to various social issues, such as experimenting with alcohol, among others. Although alcohol consumption was proven to be detrimental to physical and cognitive development toward adulthood, and almost one in 10 Malaysian adolescents aged 13 years and above are current drinkers, studies concerning the driving factors are still scarce. This cross-sectional study aimed to determine alcohol use among 244 adolescents in Nabawan, Sabah. Methods: This study assessed the associations between alcohol use and three potential factors: demographic, environmental, and psychological. Respondents who were selected through stratified proportionate random sampling answered a set of assessment tools. Results: Results showed that 30.7% (95% confidence interval [CI], 24.91-36.48) of Nabawan adolescents use alcohol. Analysis revealed that older age adolescents 18 years and 19 years, respectively (adjusted odds ratio [aOR], 3.93; P=0.021; aOR, 5.38; P=0.003), having parents (aOR, 4.11; P=0.001) and peers (aOR, 11.57; P<0.001) who consume alcohol were significantly associated with alcohol use. Unexpectedly, good parental monitoring (aOR, 2.46; P=0.019) and discussing serious problems with parents (aOR, 3.86; P=0.001) were significantly associated with alcohol use. Conclusion: Conclusively, policies on alcohol-related harm reduction and prevention should be developed, especially school-based programs, programs addressing family functioning, and parent-child communication, among others, should be further looked into. Future research on the school environment, adolescents' drinking motives, and the development of practical adolescent-friendly alcohol screening tools are recommendations for improvements.

The incidence, and spatial trends of cholera in Sabah over 15 years: Repeated outbreaks in coastal areas.

Vibrio cholerae remains a notable public health challenge across Malaysia. Although the Malaysian state of Sabah is considered a cholera-affected area, gaps remain in understanding the epidemiological trends and spatial distribution of outbreaks. Therefore, to determine longitudinal and spatial trends in cholera cases data were obtained from the Sabah State Health Department for all notified cases of cholera between 2005-2020. A cholera outbreak is defined as one or more confirmed cases in a single locality with the evidence of local transmission. All records were geolocated to village level. Satellite-derived data and generalised linearized models were used to assess potential risk factors, including population density, elevation, and distance to the sea. Spatiotemporal clustering of reported cholera cases and zones of increased cholera risk were evaluated using the tau statistic (τ) at 550m, 5km and 10km distances. Over a 15-year period between 2005-2020, 2865 cholera cases were recorded in Sabah, with a mean incidence rate of 5.6 cases per 100,000 (95% CI: 3.4-7.9). From 2015-2020, 705 symptomatic cases and 727 asymptomatic cases were reported. Symptomatic cases primarily occurred in local Malaysian populations (62.6%, 441/705) and in children and adolescents under 15-years old (49.4%, 348/705). On average, cases were reported in areas with low population density (19.45 persons/km2), low elevations (19.45m) and near coastal areas. Spatiotemporal clustering of cholera cases was identified up to 3.5km, with increased village-level cholera risk within 500m and 5 days of initial case presentation to a health facility (Risk Ratio = 9.7, 95% CI: 7.5-12.4). Cholera incidence has high spatial and temporal heterogeneity within Sabah, with some districts experiencing repeated outbreaks. Cholera cases clustered across space and time, with village-level risk of cholera highest within 5 days and within close proximity to primary case villages, suggesting local transmission.

Survival Rate and Prognostic Factors for Colorectal Cancer in Sabah, Borneo, Malaysia: A Retrospective Cohort of a Population-Based Study.

BACKGROUND: Colorectal cancer is a major public health problem with significant number of cases and death in the population. This study aimed to determine the 5-year overall survival rate and the prognostic factors for colorectal cancer patients in Sabah. METHODS: This was a retrospective cohort study conducted using secondary data from Malaysian National Cancer Registry (MNCR) database. A 5-year overall survival and the median survival time were determined with Kaplan-Meier survival curve. Cox regression analysis was done to determine the prognostic factors on survival. RESULTS: A total of 1,152 patients were included in this study. The majority of the patients had colon cancer and presented at late stage (stage III and IV) as compared to early stage (stage I and II). From the analysis, the 5-year overall survival for colorectal cancer was 23.2% (95% CI: 21.8, 24.6) and the median survival time was 16 months (95% CI: 14.3, 17.7).  Higher survivals are seen in males (23.6%, 95% CI: 20.4, 24.7), aged 50-74 years old (24.2%, 95% CI: 22.4, 26.0), Chinese (25.5%, 95% CI: 23.0, 28.0), lived in Keningau (25.6%, 95% CI: 20.8, 30.4), colon as primary tumor site (24.5%, 95% CI: 22.5, 26.4), diagnosed with stage I (55.6%, 95% CI: 48.7, 62.5) and received surgery with chemotherapy or radiotherapy (31.3%, 95% CI: 27.8, 34.8). The significant prognostic factor was the stage at diagnosis. Patients with stage IV colorectal cancer (HR: 11.18; 95% CI: 3.48, 35.93) had eleven times risk of dying as compared to stage I. CONCLUSION: The survival rate for colorectal cancer patients in Sabah was comparatively lower than other states in Malaysia and in some Asian countries. Those patients who presented at later stage had poorer survival. Health promotion and community-based screening program should be emphasized in addition to encouraging early diagnosis to improve survival.

The Association of Eating Behaviour on the Growth of Children from the Interior Districts of Sabah, Malaysia.

Background: The double burden of malnutrition among children is an emerging public health problem, especially in developing countries. Eating behaviours have been hypothesised to contribute to both being underweight and overweight in children and adults. The objective of this study was to examine the association between the Child Eating Behaviour Questionnaire (CEBQ) subscale scores and body mass index (BMI) z-scores among Malaysian children under-5 years. Methods: This was a cross-sectional study conducted in 2020 by recruiting a sample of 500 children aged 24-59 months old from clinics located in the interior districts of Sabah, Malaysia. The CEBQ was completed by the mothers on behalf of the child to assess their eating behaviour traits. The height and weight of the child were measured using standardised instrument. The BMI-for-age percentile, z-scores for BMI-for-age, height-for-age and weight-for-age were determined and classified using World Health Organization AnthroPlus software. The relationship between the CEBQ subscale scores and BMI z-scores were evaluated using multiple linear regression models adjusting for potential confounders. Results: The prevalence of underweight, stunting and wasting were 20.2%, 29.2% and 5.6%, respectively, whereas the prevalence of overweight and obese was 5.0%. There were significant positive association between Food responsiveness, Emotional overeating, Enjoyment of food with BMI z-scores (p<0.05; unstandardised regression coefficient: 0.17 to 0.38). In contrast, there were significant negative association between Satiety responsiveness, Slowness of eating, Food fussiness with BMI z-scores (p<0.01; unstandardised regression coefficient: -0.35 to -0.36). Conclusion: These findings show that specific eating behaviours can influence the growth of children under-5 years. Therefore, policymakers should formulate a nutrition policy that incorporates behavioural assessment and behavioural intervention in the prevention and management of malnutrition among children in Malaysia.

Prevalence of occupational injury and determination of safety climate in small scale manufacturing industry: A cross-sectional study.

BACKGROUND: Occupational injuries are among the most important workplace issues. This study aims to determine the safety climate and prevalence of occupational injuries in the small-scale manufacturing industry. METHODS: A cross-sectional study with ten small scale manufacturers participated accounting for a total of 300 respondents. Data were collected from July to August 2020 using the NOSACQ-50 questionnaire. RESULTS: The prevalence of occupational injury for the past 12 months was at 18%. The most often injured body parts were hands and legs while among the most common injury types were open wound, burns and bleeding. The mean NOSACQ-50 scores for all dimensions are good. The associated factors are working hours per week, and compliance to SOP. There are differences in the mean scores of NOSACQ-50 between injured and non-injured workers across all dimensions. CONCLUSION: The safety climate among manufacturing industry employees is at a good level, while the prevalence of occupational injury is relatively low.

Relationship of self-reported body size and shape with risk for prostate cancer: A UK case-control study.

INTRODUCTION: Previous evidence has suggested a relationship between male self-reported body size and the risk of developing prostate cancer. In this UK-wide case-control study, we have explored the possible association of prostate cancer risk with male self-reported body size. We also investigated body shape as a surrogate marker for fat deposition around the body. As obesity and excessive adiposity have been linked with increased risk for developing a number of different cancers, further investigation of self-reported body size and shape and their potential relationship with prostate cancer was considered to be appropriate. OBJECTIVE: The study objective was to investigate whether underlying associations exist between prostate cancer risk and male self-reported body size and shape. METHODS: Data were collected from a large case-control study of men (1928 cases and 2043 controls) using self-administered questionnaires. Data from self-reported pictograms of perceived body size relating to three decades of life (20's, 30's and 40's) were recorded and analysed, including the pattern of change. The associations of self-identified body shape with prostate cancer risk were also explored. RESULTS: Self-reported body size for men in their 20's, 30's and 40's did not appear to be associated with prostate cancer risk. More than half of the subjects reported an increase in self-reported body size throughout these three decades of life. Furthermore, no association was observed between self-reported body size changes and prostate cancer risk. Using 'symmetrical' body shape as a reference group, subjects with an 'apple' shape showed a significant 27% reduction in risk (Odds ratio = 0.73, 95% C.I. 0.57-0.92). CONCLUSIONS: Change in self-reported body size throughout early to mid-adulthood in males is not a significant risk factor for the development of prostate cancer. Body shape indicative of body fat distribution suggested that an 'apple' body shape was protective and inversely associated with prostate cancer risk when compared with 'symmetrical' shape. Further studies which investigate prostate cancer risk and possible relationships with genetic factors known to influence body shape may shed further light on any underlying associations.

Factors Affecting Continued Participation in Tuberculosis Contact Investigation in a Low-Income, High-Burden Setting.

SETTING: Outpatient clinics, Kota Kinabalu, Malaysia; January-April 2018. OBJECTIVES: To identify barriers to full participation in tuberculosis (TB) contact investigation. METHODS: Cross-sectional study of knowledge, perceptions, and behaviours among TB contacts. This study was conducted among contacts who attended an initial clinic visit to explore retention in care. During this first visit, contacts were approached for participation in a questionnaire at a follow-up visit. Contacts who consented but did not subsequently attend were interviewed at home. Associations between questionnaire findings and attendance were tested using logistic regression. RESULTS: Of the total 1436 identified contacts, 800 (56%) attended an initial clinic visit. Of 237 consenting TB contacts, 207 (87%) attended their follow-up appointment. In univariable analyses, the odds of attendance were highest for people notified to attend the TB clinic directly by a health inspector; close relatives of TB patients; non-students; people with higher incomes and smaller households; older individuals; males; and people not perceiving TB as stigmatising. In multivariable analysis, mode of notification to attend and having a close relative with TB remained significant. CONCLUSIONS: Health inspectors provide an effective role in TB contact investigation through direct personal communication to encourage the completion of the TB screening process, but this requires further integration with clinical processes, and with workplace and school-based investigations.

Factors Influencing Attitude Toward Organ and Tissue Donation Among Patients in Primary Clinic, Sabah, Malaysia.

INTRODUCTION: Worldwide, the gap between organ supply and demand has widened over the years. Malaysia has one of the lowest deceased organ donation rates. Success rate of organ or tissue procurement depends on not only the approach rate by health care providers but also the awareness among the public, whereby it can be a platform for family initiation of organ donation. The purpose of this study is to assess the knowledge of and determine the factors influencing attitude toward organ and tissue donation among patients in a primary clinic. METHODS: A cross-sectional analytical study was carried out. Self-administered questionnaires were given to 400 patients who registered at an outpatient clinic in April 2018. Convenience sampling was applied. RESULTS: Monthly income, education level, occupation, and knowledge level are significantly associated with attitude of the respondents toward organ and tissue donation. Occupation influenced attitude toward organ donation. Knowledge of organ donation and brain death both significantly affected attitude toward organ donation. CONCLUSION: The greater the knowledge of organ donation and brain death, the more positive impression or attitude toward organ donation. Education level and income are the main predictors that influence attitude toward organ donation. Hence, it is important for public health units to promote and deliver public education on organ donation, change public misconceptions, and work parallel with hospitals to increase organ donation rates in Sabah.

Clarifying the debate on population-based screening for breast cancer with mammography: A systematic review of randomized controlled trials on mammography with Bayesian meta-analysis and causal model.

BACKGROUND: The recent controversy about using mammography to screen for breast cancer based on randomized controlled trials over 3 decades in Western countries has not only eclipsed the paradigm of evidence-based medicine, but also puts health decision-makers in countries where breast cancer screening is still being considered in a dilemma to adopt or abandon such a well-established screening modality. METHODS: We reanalyzed the empirical data from the Health Insurance Plan trial in 1963 to the UK age trial in 1991 and their follow-up data published until 2015. We first performed Bayesian conjugated meta-analyses on the heterogeneity of attendance rate, sensitivity, and over-detection and their impacts on advanced stage breast cancer and death from breast cancer across trials using Bayesian Poisson fixed- and random-effect regression model. Bayesian meta-analysis of causal model was then developed to assess a cascade of causal relationships regarding the impact of both attendance and sensitivity on 2 main outcomes. RESULTS: The causes of heterogeneity responsible for the disparities across the trials were clearly manifested in 3 components. The attendance rate ranged from 61.3% to 90.4%. The sensitivity estimates show substantial variation from 57.26% to 87.97% but improved with time from 64% in 1963 to 82% in 1980 when Bayesian conjugated meta-analysis was conducted in chronological order. The percentage of over-detection shows a wide range from 0% to 28%, adjusting for long lead-time. The impacts of the attendance rate and sensitivity on the 2 main outcomes were statistically significant. Causal inference made by linking these causal relationships with emphasis on the heterogeneity of the attendance rate and sensitivity accounted for the variation in the reduction of advanced breast cancer (none-30%) and of mortality (none-31%). We estimated a 33% (95% CI: 24-42%) and 13% (95% CI: 6-20%) breast cancer mortality reduction for the best scenario (90% attendance rate and 95% sensitivity) and the poor scenario (30% attendance rate and 55% sensitivity), respectively. CONCLUSION: Elucidating the scenarios from high to low performance and learning from the experiences of these trials helps screening policy-makers contemplate on how to avoid errors made in ineffective studies and emulate the effective studies to save women lives.
