The increased prevalence of unhealthy eating habits and sedentary lifestyles among Malaysian adolescents has become a public health concern. The aim of this systematic review was to summarize evidence from observational studies related to diet and physical activity (PA) among Malaysian adolescents (13–18 years) and to recognize the associations between determinants of diet and PA and diet and PA behaviours. A systematic search for observational studies published from August 1990 through August 2017 was conducted via PubMed, Science Direct, Cochrane and Web of Science. A total of 18 studies met the inclusion criteria; these were independently extracted by two reviewers. Gender and ethnicity were the most commonly studied correlates of diet and PA; males were more physically active and they tended to have poorer diet quality and higher energy and macronutrient intakes in comparison to females; Malay adolescents had a lower diet quality and Chinese adolescents spent less time in PA compared to other ethnicities. However, the significance of these associations was often small or inconsistent. This review highlights the lack of longitudinal observational studies but summarizes the best available evidence for policymakers and public health practitioners to improve the diet and the level of PA in Malaysian adolescents.

Following fast increase in the incidence of type 2 diabetes among Iranians, diabetes self-care activities are important. This cross-sectional study was carried out to evaluate the knowledge, attitude and practices regarding diabetes among 100 Iranian type 2 diabetics (61 female, 39 male) aged between 37 to 66 years, attending the out-patient Diabetes Clinic at Golestan Hospital, Ahvaz, Iran. A face-to-face interview was done and a validated knowledge, attitude and practice (KAP) questionnaire was used to determine knowledge, attitude and practices of diabetes patients. The mean duration of diabetes among patients was 4.05 ± 1.4 years. Fifty three percent of patients had good glycemic control (HbA1c level (=<7%)). The results showed that attitude related to diabetes was acceptable in the majority; while knowledge and self-care practices were insufficient. The overall mean (± SD) score of the knowledge, attitude and practice of patients based on KAP questionnaire was in medium level (17.37± 2.23) in which total maximum possible score was 29. KAP score was low for 9 % of patients. There was significant association between low level of education (primary) or not having formal education with poor KAP score about diabetes compare to higher level of education [illiterate: OR=2.6, 95% CI= (0.23-30.80), primary: OR=0.23, 95% CI= (0.43-1.27), P<0.05]. While there was no significant association between the KAP scores and HbA1c level. As the consequence of low awareness of diabetes among patients affects their ability of self-care management and lead to negative impact on outcome of diabetes. Patients need to be educated on how to prevent diabetes complications. Health care providers should promote self-care activities in the process of diabetes education.

Objective: To conduct formative research using qualitative methods among stakeholders of secondary schools to explore their perceptions, barriers and facilitators related to healthy eating and physical activity (PA) among Malaysian adolescents.Design: A qualitative study involving eight focus groups and twelve in-depth interviews. Focus groups and interviews were recorded and transcribed verbatim. An inductive thematic analysis approach was used to analyse the data.Setting: Four secondary schools in Perak and Selangor states (two urban and two rural schools) in Malaysia.Participants: Focus groups were conducted with seventy-six adolescents aged 13–14 years, and in-depth interviews were conducted with four headmasters, four PA education teachers and four food canteen operators.Results: Stakeholders thought that adolescents’ misperceptions, limited availability of healthy options, unhealthy food preferences and affordability were important challenges preventing healthy eating at school. Low-quality physical education (PE) classes, limited adolescent participation and teachers’ commitment during lessons were perceived as barriers to adolescents being active at school. Affordability was the main challenge for adolescents from rural schools. Stakeholders perceived that a future school-based intervention should improve the availability and subsidies for healthy foods, provide health education/training for both adolescents and PE teachers, enhance active adolescent participation in PE and develop social support mechanisms to facilitate engagement with PA.Conclusions: These findings provide important insights into developing school-based lifestyle interventions to improve healthy eating and strengthening PA of Malaysian adolescents.

Nutritional status and dietary intake play a significant role in the prognosis of breast cancer and may modify the progression of disease. The aim of this study was to determine the influence of nutritional status on the quality of life of Iranian breast cancer survivors. Cross-sectional data were collected for 100 Iranian breast cancer survivors, aged 32 to 61 years, attending the oncology outpatient clinic at Golestan Hospital, Ahvaz, Iran. Nutritional status of subjects was assessed by anthropometric measurements, Patient-Generated Subjective Global Assessment (PG-SGA) and three non-consecutive 24-hour diet recalls. The European Organization of Research and Treatment of Cancer Quality of Life form (EORTC QLQ-C30) was used to assess quality of life. Ninety-four percent of the survivors were well-nourished, 6% were moderately malnourished or suspected of being malnourished while none were severely malnourished. Prevalence of overweight and obesity was 86%. Overall, participants had an inadequate intake of vitamin D, E, iron and magnesium according to dietary reference intake (DRI) recommendations. Survivors with better nutritional status had better functioning scales and experienced fewer clinical symptoms. It appears important to provide educational and nutritional screening programs to improve cancer survivor quality of life.
