RESUMO
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.
RESUMO
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.
