Introduction: There is limited data on childhood obesity and its impact on children from diverse cultural backgrounds. This study is aimed at determining the association between obesity, self-esteem and health-related quality of life (HRQOL) among Malaysian urban primary school children of different ethnicity. Methods: A cross-sectional study was conducted involving 311 children aged 11-13 years from primary schools in Kuching, Sarawak. Self-esteem and healthrelated quality of life (HRQOL) were measured using the Lawrence Self-esteem Questionnaire (LAWSEQ) questionnaire and the Paediatric Quality of Life Inventory (PedsQL), respectively. Body weight and height were taken and body mass index for age calculated. Results: The prevalence of overweight and obesity among the children were 18.2% and 15.2% respectively. Parent-proxy and child self-reported PedsQL scores were higher for normal weight children compared to thin and obese children, but lower than overweight children. At the subscale level, only parent-proxy PedsQL scores in psychosocial health and emotional component were significantly different between overweight and obese children (p=0.019, p=0.02). The Self-esteem score was significantly correlated with parent and child PedsQL scores. Although obesity was associated with lower HRQOL among children, both parent and child PedsQL scores among the overweight group were higher than that for the normal weight group. Overweight and obesity did affect quality of life and self-esteem of children in this study, particularly in the areas of psychosocial and emotional health. Conclusion: Policy makers and programme managers should take into consideration the impact of obesity on children and parents in designing intervention programmes.

Surgical traineeship has traditionally been based on a master apprentice model where learning takes place in the operating theatre. This approach has changed over the past few years with greater emphasis on surgical training taking place within the surgical skills laboratory. We developed a high fidelity simulator, the Image-guided Robotic Assisted Surgical simulator (IRAS) with an incorporated robotic guidance feature. The robot system is developed to mimic the process of an experienced surgeon physically holding a trainee's hands to demonstrate maneuvering of the laparoscopic instruments. We aimed to assess the efficacy of incorporating robotic guidance into this high fidelity surgical simulator. Forty-two participants (13 surgical residents and 29 medical students) were recruited. Participants had one practice run for familiarisation and subsequently performed the virtual laparoscopic cholecystectomy (LC) once. Among the medical students, they were ransomised to either a control or intervention group. They were tasked to perform a second- and third-timed LC assessment. Participants were asked to rate the simulator using a 5-point Likert scale Questionnaire. IRAS rated favourably in hand-eye coordination and training bimanual dexterity (mean score: 4.1 and 4.0 among students, 3.4 and 3.4 among residents) though it faired suboptimally in realism. At baseline, residents were statistically faster compared to students (overall time: 418.9 vs 586.8 seconds,= 0.001). Participants randomised to the intervention group consistently scored better. However, their overall time were not statistically significant from the control group. The robotic guidance capability of the IRAS is a key advantage of this simulator platform over the conventional platform.

Introduction: This is a preliminary result of an on-going randomised cross-over trial to compare the effects of consuming yellowstripe scad (YSS) and salmon, both rich in omega-3 fatty acids, on lipid profile, fasting glucose, body weight status, and blood pressure among healthy overweight adults. Methods: Fifty healthy overweight Malaysians aged 21-55 years were recruited voluntarily through advertisements. During the first period of intervention, subjects were randomised equally to receive eight weeks of either steamed whole YSS fish (YSS group) or salmon fillet (salmon group), three days per week, obtaining approximately 7000 mg EPA+DHA per week. The diets were switched after an eight-week washout period. Lipid profile, fasting glucose, body mass index, and blood pressure were evaluated before and after each intervention period. Results: The mean ages of YSS group (n=25) and salmon (n=25) group were 30.6?±9.1 and 27.9?±7.1 years respectively. Both groups had no statistically significant differences on socio-demographic characteristics (p>0.05). After the first intervention period, there was a significant increase in total cholesterol within the YSS group (p<0.05) but not within the salmon group (p>0.05). Both YSS and salmon groups had significantly higher HDL-cholesterol levels after 8 weeks compared to baseline (p<0.05). There was no significant between-group difference in all the variables after eight weeks (time x group interaction, p>0.05). However, there was a significant effect of time on diastolic blood pressure (p<0.05). Conclusion: These preliminary findings indicate that YSS and salmon may have similar beneficial effects on HDL-cholesterol level among healthy overweight adults. The second intervention period is on-going to confirm these finding

Introduction: The present study aimed to determine the prevalence of hypertension and itsassociation with nutritional status (body mass index, body fat percentage, and visceral fat) amongstudents in a public university in Sarawak, Malaysia.Methods: This was a cross-sectional study among undergraduate students aged 18 years old andabove. Anthropometric measurements, such as weight, height, body composition, and bloodpressure measurements, were collected. Hypertension was defined as equal or more than 140/90mmHg. Statistical analyses were done using IBM SPSS version 20.Results: A total of 354 respondents participated in the study. Mean age for the respondents was21 years (SD 1.18 years). About 40% of the respondents were overweight or obese. Prevalence ofhypertension was 8.2%. Mean systolic blood pressure was 119.1mmHg (SD14.36mmHg), and themean diastolic blood pressure was 72.6mmHg (SD 9.73mmHg). There is a significant associationbetween male gender (odds ratio =3.519, 95% CI is 1.886-6.566), body fat percentage (odds ratio=1.944, 95% CI is 1.050-3.601), visceral fat (odds ratio = 2.830, 95% CI is 1.346-5.951), andfamily history of hypertension (odds ratio= 2.366, 95% CI is 1.334-4.194) and hypertension.Conclusion: The prevalence of hypertension was less than 10% and is associated with malegender, body composition, and family history of hypertension.
