Introduction: Polypharmacy and potentially inappropriate prescribing (PIP) are increasingly recognised as important contributors to medication -related harm among older adults. However, published national data on the prevalence of polypharmacy and PIP in Brunei Darussalam are unavailable. The objectives of this study was to determine the prevalence of polypharmacy and PIP among adults aged 65 years and above in Brunei Darussalam using Screening Tool of Older Persons ’ potentially inappropriate Prescriptions (STOPP) version 2 criteria. Materials and Methods: A retrospective cross -sectional study was conducted using data from the Brunei Healthcare Information Management System (Bru -HIMS). A stratified proportional random sample of 2,000 older adults with documented medical encounters in 2016 was selected. Polypharmacy was defined as the concurrent use of five or more medications. PIP was assessed using STOPP version 2 criteria. Descriptive statistics were used to summarise prescribing patterns. Results: Of the 2000 older adults included (mean age 73.0 ± 6.6 years), 1,181 (59.1%) had polypharmacy. Among those with polypharmacy, 1,057 (89.5%) could be assessed using STOPP criteria, and 206 (19.5%) had at least one PIP. The most frequently identified PIPs involved prolonged use of proton pump inhibitors for uncomplicated peptic ulcer disease at full therapeutic dosage for more than eight weeks, where dose reduction, discontinuation, or transition to maintenance therapy (e.g. H2 receptor antagonists) is indicated, prescribing without evidence -based indication, duplication of drug classes, use of ACE inhibitors or angiotensin receptor blockers in patients with hyperkalaemia, and use of first -generation antihistamines. Conclusion: Polypharmacy and PIP are common among older adults in Brunei Darussalam. The findings highlight the need for systematic medication review and deprescribing strategies to optimise pharmacotherapy and improve medication safety in older populations

Introduction: Poor appetite is prevalent among older adults and may negatively
impact on their overall health. This is especially true for institutionalised residents.
Despite this, there is a paucity of research on appetite and its associated factors
among institutionalised residents, which signified the present study. Methods: A
cross-sectional study was conducted among elderly residents at long-term care
facilities in the state of Selangor, Malaysia to ascertain their appetite status and its
associated factors. Results: A total of 97 residents with mean age of 74.2±8.4 years
old were recruited. They comprised 61.9% females and 38.1% males. More than
50% had poor appetite with early satiety. There were 63.0%, 82.4%, and 94.8% who
had poor oral health, poor sleep quality, and depression, respectively. Ethnicity
(OR=2.73; 95% CI=1.00-7.44; p=0.049) was the only factor that predicted poor appetite
among older adults in long-term care facilities, with Malay residents having poorer
appetite than their Chinese and Indian counterparts. Conclusion: The prevalence
of poor appetite was high among residents staying at long-term care facilities in
Selangor, Malaysia, especially among Malays. This issue deserves further studies
to identify the specific underlying factors contributing to poor appetite among older
adults from different ethnicities. Acknowledging the high prevalence of poor appetite
among older adults and its possible unfavourable outcomes, appropriate nutrition
interventions are therefore needed to address this issue among institutionalised
elderly.

Introduction: Premarital sexual is a sexual and reproductive health concern among adolescents in Malaysia. Guided
by the constructs of the Social Cognitive Theory (SCT), this study aimed to determine the moderating role of gender
on premarital sexual practices among the late adolescents in Kuantan, Pahang. Methods: Probability sampling was
utilized to sample the late adolescents from tertiary educational centres. Confirmatory factor analysis (CFA) was conducted to verify the factor structure of the observed variables, with the interrelationship between variables were studied using structural equation modelling (SEM). Moderation analysis was completed via multigroup analysis (MGA).
Results: A response rate of 72.2% was obtained, with 390 adolescents aged 18 to 19 years old participated in the
study. The total mean for premarital sexual practices was 1.14 ± 0.47, with highest mean observed for masturbation
(1.33 ± 0.83). Attitude (β = -0.111, p = 0.021), religiosity (β = -0.014, p = 0.032) and high-risk activities (β = 0.999,
p < 0.001) illustrated significant relationships with premarital sexual practices. A moderated regression analysis
showed significant interactive effects between gender and premarital sexual practices, with negative association
between attitude and religiosity with premarital sexual practices were found among male respondents. Conclusion:
This empirical study demonstrated significant moderation effect of gender between attitude and religiosity with premarital sexual practices among targeted late adolescents’ population in Pahang, Malaysia. Any efforts to tackle issue
related to premarital sexual practices among similar population should be directed towards male adolescents with
lower religiosity score.

Introduction: Khat chewing has been a common habit throughout the Horn of Africa and the Arabian Peninsula for
thousands of years. It is estimated that more than 20 million people in Africa and the Arabian Peninsula are adolescents. This study aimed to assess the knowledge, attitude, and self-efficacy of khat chewing among adolescents in
Mogadishu, Somalia. Method: A cross-sectional study with a sample of 284 adolescents was used. A self-administered pretested questionnaire was used after obtaining an ethical approval from Universiti Putr Malaysia. Data were
coded, entered, and statistically analyzed. Results: The prevalence of khat chewing among respondents was 10.2%.
Almost more than half of the participants had poor knowledge (184, 64.8%) and self-efficacy (154, 54.2%), while
140 (49.3%) respondents had positive attitudes. Significant predictors of the students’ knowledge of khat chewing
included monthly income of more than 500$ (AOR: 2.145), family history such as cousin (AOR=0.347), fathers
with a high school (AOR=1.75) and a college degree (AOR=2.21). Significant predictors of the students’ attitude
towards khat chewing included family income of 100-299 USD (AOR=0.5), fathers’ with a high school (AOR=2.5)
and college (AOR=2.4). Significant predictors of the students’ self-efficacy to resist khat chewing included family
income of 100- 300$ (AOR=2.25), fathers with a high school (AOR=2.6), and khat accessibility that is fairly difficult
(AOR=0.63) and fairly easy (AOR=0.55). Conclusion: The study highlights the need for increased awareness and education about the adverse effects of khat chewing and the importance of addressing social norms and peer pressure
in shaping adolescent attitudes toward Khat.

Introduction: The instructor-led CPR training method has been used for over 4 decades. However, nurses’ knowledge and skills are still low. Instructor-led CPR training is an extremely capital-intensive programme that requires more time, workforce, and space, thus serving as an impediment to effective learning among the prospective nurses’ trainees. Self-directed training method is suggested to improve the knowledge and skills of CPR among healthcare practitioners due to the low cost and flexibility. This study aims to evaluate the effectiveness of self-directed method in improving nurses’ knowledge and skill retention from baseline to post-test, one, three-, and six months. Method: A two-arm double-blinded randomised controlled trial will be conducted in two referral hospitals. The control group
training consists of a one-day session taught by AHA-certified instructors, whereas the intervention group training entails participants learning on computers in a simulation lab for seven days. A generalised estimated equation model will be used for statistical analysis. Discussion: Through the self-directed training method, participants will have significantly better knowledge and skills of CPR compared to the conversational training method across the time points. Self-directed training method is a simple, cost-effective and flexible method, which can facilitate the training of more nurses in the acquisition and retention of knowledge and skills, especially for those who prefer to learn at their own
pace. Trial Registration: Registration Code: UDUTH/NHREC/30/012/2019 and NHREC/28/01/2020/AKTH/EC/2934

Introduction: Malaria is a vector-borne disease caused by the bites of infected female mosquitoes that transmit the
parasite to humans. In Guinea, the entire population is at risk of malaria infection. The objective of this study is to
develop, implement and evaluate the effectiveness of the Malaria Free Zone program using the Health Belief Model
(HBM) to improve malaria prevention knowledge, attitudes, and practices among university students in Conakry,
Guinea. Methods: The study design is a clustered randomized controlled trial (RCT). Students are selected using the
clustered sampling method, with each university representing one group, either the intervention or control group.
The sample size is 113 university students from each group. The content of the Malaria Free Zone program includes
eight sessions, which are based on the HBM constructs. This program takes approximately 6 hours and 30 minutes
to complete. Respondents are required to complete a questionnaire over four time points. Generalized Estimating
Equation (GEE) will be used to determine the effectiveness of the Malaria Free Zone program on malaria prevention
knowledge, attitudes, and practices, adjusted with covariates. Conclusion: It is expected that there will be a significant difference in knowledge, attitude, and practice of malaria prevention in the post-test, 2-week and 2-month
follow up of the intervention group after the Malaria Free Zone program. Students in the intervention group will have
significant higher knowledge, attitude and practice of malaria prevention compared to students in the control group.

Introduction: Premarital sexual behaviour remains an important sexual and reproductive health issue among adolescents in Malaysia. It is also a prohibited act and considered sinful among the Muslims community. This study aimed
to identify the determinants of premarital sexual behaviour among the late adolescents age group in Pahang, Malaysia. Methods: An observational study was conducted among eligible late adolescents, which were recruited using
probability sampling method. Only those aged 18 to19 years old, and previously attended the public secondary
schools in Malaysia were included, with non-Malaysian, married and those who were absent during the data collection day were excluded. Data was collected using a valid and reliable set of questionnaires measuring the personal
(demographic profile, knowledge and attitude), behavioural (premarital sexual behaviour and high-risk activities)
and environmental (subjective norms and perceived parental communication) factors. Multiple logistic regression
analysis was conducted to identify the determinants of premarital sexual behaviour. Results: A total of 390 adolescents aged 18 and 19 years old participated in this study, with 82.3% of respondents reported never had premarital
sexual behaviour. Multiple logistic regression showed that the male and engagement in high-risk activities had higher
odds in premarital sexual behaviour respectively (AOR =11.649, 95% CI: 3.615,37.536, p <0.001; AOR=19.224,
95% CI: 7.820,47.262, p <0.001). Conclusion: Male gender and engagement in high-risk activities remained important risk factors towards the ongoing concern related to premarital sexual behaviour among adolescents in Malaysia.
Failure to address this issue should be explored and improve accordingly.

Introduction: There is a strong body of evidence advocating parent training programmes in the management of behavioral problems in children. In these programmes, attrition is a major challenge. We aimed to examine the sociodemographic and clinical profiles, parental motivation, and pre-intervention severity of children’s behavioural problems as rated by mothers who completed (PC) and mothers who dropped out (PD) of a parent training programme.
We also aimed to determine whether there was any change in their children’s behaviour scores before and after
intervention. We hypothesized that parent and child sociodemographic and clinical profiles, parental motivation,
and pre-intervention severity of children’s behavioural problems would be different between PC and PD, and that
children of PC would experience significant improvements in their behaviour. Methods: Data from a randomised
controlled trial (RCT) involving 35 mothers and children aged 6–12 years old with behavioural problems who were
enrolled in a parent training programme were examined. Child behaviour was measured using the Strength and Difficulties Questionnaire. Results: No significant differences were found between PC and PD in terms of the sociodemographic and clinical profiles, parental motivation, and pre- or post-intervention child behaviour. After programme
completion, PC (n=27) reported improvements in all the behaviour subscales; total difficulties (p<0.001), emotional
problem (p=0.004), conduct problem (p=0.001), hyperactivity symptoms (p<0.001), peer problems (p=0.036), and
prosocial behaviour (p=0.001). Conclusion: The parent training programme produces significant child behaviour
improvements in mothers who complete the programme. Nonetheless, the study has some limitations which restrict
the generalizability of these findings.

Introduction: Over the last decade, tuberculosis (TB) has remained the main cause of death from communicable
diseases in Malaysia. This study was aimed to determine the risk factors of unfavourable treatment outcomes (UTO)
among new TB cases in Hulu Langat. Methods: A cohort study was prospectively conducted among the new TB
cases registered in the government health clinics of Hulu Langat district. The event was defined as any one of the
UTO (default, transferred out, treatment failure and death) whichever came first. This data was analysed using SPSS
version 25.0. Survival pattern was assessed by Kaplan-Meier plots and Log rank test. Hazard ratios of unfavourable
TB treatment outcomes among the new TB cases at 95% confidence interval and level of significance set at 0.05 were
calculated using Cox proportional hazard model. Results: Of the 321 patients analysed, 80.4% (n=258) had favourable treatment outcomes and 19.6% (n=63) had UTO with 10.9% (n=35) transferred out, 6.9% (n=22) defaulted and
1.9% (n=6) died. There was no treatment failure. The mean survival time was 5.2 (SD=0.09) months. The risk factors
of hazard probability of UTO were male, ethnicity type Others, positive human immunodeficiency virus (HIV) status
and not done sputum at 2 months of treatment. Conclusion: Transferred out and default formed the bulk of the UTO
in Hulu Langat. New interventions to improve the existing TB prevention and control program should be planned in
the first three months of treatment.
