METHODS: An analytical cross-sectional study using purposive sampling method was conducted at eight thalassemia societies in Peninsular Malaysia. 260 respondents comprised of patients and caregivers were assessed with two separate sets of questionnaires.
RESULTS: Knowledge on dietary iron among the respondents was unsatisfactory, despite them having good knowledge on thalassemia disorder. Female patients were found to have better dietary knowledge, attitude and practice compared to males. The percentage of caregivers with good attitude and good practice were significantly higher compared to adult patients. Caregivers with children on iron chelators were noted to have better dietary attitude and practice. Thalassemia knowledge and children on vitamins were found to be the predictors of dietary knowledge among the patients and caregivers respectively.
CONCLUSION: The level of knowledge on dietary iron among the patients and caregivers was unsatisfactory in spite of their attitude and practice towards dietary iron were good. Effective delivery of dietary information to the patients and caregivers is essential to enable them to choose a healthy diet for their condition.
OBJECTIVE: We aimed to identify a posteriori dietary patterns for Chinese, Malay, and Indian ethnic groups in an urban Asian setting, compare these with a priori dietary patterns, and ascertain associations with cardiovascular disease risk factors including hypertension, obesity, and abnormal blood lipid concentrations.
METHODS: We used cross-sectional data from 8433 Singapore residents (aged 21-94 y) from the Multi-Ethnic Cohort study of Chinese, Malay, and Indian ethnicity. Food consumption was assessed using a validated 169-item food-frequency questionnaire. With the use of 28 food groups, dietary patterns were derived by principal component analysis, and their association with cardiovascular disease risk factors was assessed using multiple linear regression. Associations between derived patterns and a priori patterns (aHEI-2010-Alternative Healthy Eating Index-2010, aMED-alternate Mediterranean Diet, and DASH-Dietary Approaches to Stop Hypertension) were assessed, and the magnitude of associations with risk factors compared.
RESULTS: We identified a "healthy" dietary pattern, similar across ethnic groups, and characterized by high intakes of whole grains, fruit, dairy, vegetables, and unsaturated cooking oil and low intakes of Western fast foods, sugar-sweetened beverages, poultry, processed meat, and flavored rice. This "healthy" pattern was inversely associated with body mass index (BMI; in kg/m2) (-0.26 per 1 SD of the pattern score; 95% CI: -0.36, -0.16), waist circumference (-0.57 cm; 95% CI: -0.82, -0.32), total cholesterol (-0.070 mmol/L; 95% CI: -0.091, -0.048), LDL cholesterol (-0.054 mmol/L; 95% CI: -0.074, -0.035), and fasting triglycerides (-0.22 mmol/L; 95% CI: -0.04, -0.004) and directly associated with HDL cholesterol (0.013 mmol/L; 95% CI: 0.006, 0.021). Generally, "healthy" pattern associations were at least as strong as a priori pattern associations with cardiovascular disease risk factors.
CONCLUSION: A healthful dietary pattern that correlated well with a priori patterns and was associated with lower BMI, serum LDL cholesterol, total cholesterol, and fasting triglyceride concentrations was identified across 3 major Asian ethnic groups.
DESIGN: Food choice was assessed using the validated New Zealand Adolescent FFQ. Principal components analysis was used to determine dietary patterns. Trained research assistants measured participants' height and body mass. Cardiorespiratory fitness was assessed in a subset of participants using the multistage 20 m shuttle run. The level and stage were recorded, and the corresponding VO2max was calculated. Differences in mean VO2max according to sex and BMI were assessed using t tests, while associations between cardiorespiratory fitness and dietary patterns were examined using linear regression analyses adjusted for age, sex, school attended, socio-economic deprivation and BMI.
SETTING: Secondary schools in Otago, New Zealand.
SUBJECTS: Students (n 279) aged 14-18 years who completed an online lifestyle survey during a class period.
RESULTS: Principal components analysis produced three dietary patterns: 'Treat Foods', 'Fruits and Vegetables' and 'Basic Foods'. The 279 participants who provided questionnaire data and completed cardiorespiratory fitness testing had a mean age of 15·7 (sd 0·9) years. Mean VO2max was 45·8 (sd 6·9) ml/kg per min. The 'Fruits and Vegetables' pattern was positively associated with VO2max in the total sample (β=0·04; 95%CI 0·02, 0·07), girls (β=0·06; 95% CI 0·03, 0·10) and boys (β=0·03; 95% CI 0·01, 0·05).
CONCLUSIONS: These results indicate that increase in cardiorespiratory fitness was associated with a healthier dietary pattern, suggesting both should be targeted as part of a global lifestyle approach. Longitudinal studies are needed to confirm this association in relation to health outcomes in New Zealand adolescents.
DESIGN: A qualitative study involving twelve focus groups.
SETTING: Two secondary schools in the district of Hulu Langat in Selangor, Malaysia.
PARTICIPANTS: Seventy-two adolescents aged 13-14 years.
RESULTS: Adolescents had some understanding regarding healthy eating and were able to relate healthy eating with the concepts of balance and moderation. The adolescents' perceptions of healthy and unhealthy eating were based on food types and characteristics, cooking methods and eating behaviours. Facilitators for healthy eating were parents' control on adolescents' food choices, feeling concern about own health and body, being influenced by other's health condition, and knowledge of healthy or unhealthy eating. On the other hand, barriers for healthy eating were the availability of food at home and school, taste and characteristics of foods, and lack of knowledge on healthy or unhealthy foods.
CONCLUSIONS: The findings contribute to a better understanding of the adolescents' concept of healthy eating, as well as the facilitators and barriers to practising healthy eating. Future interventions should include a method of promoting the immediate benefits of healthy eating, the way to cope with environmental barriers for healthy eating, and increasing the availability of healthy food choices at home and in the school environment. The health and nutrition education programmes should also focus on educating parents, as they can be role models for adolescents to practise more healthful behaviours.
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.
METHODOLOGY: This study utilized the data from the National Health and Morbidity Survey (NHMS) 2019, a cross-sectional survey that applied two-stage stratified cluster sampling. Questionnaires pertained to ever heard, knowledge, and practised of Malaysian Healthy Plate were asked along with another questionnaire. Complex sample analysis was applied to fit with the study design.
RESULTS: Estimated 16.9 million (79.6%) adults in Malaysia were never heard of the Malaysian Healthy Plate Concept in 2019. Never heard of this concept was significantly associated with sex (men, aOR 0.265), ethnicity (other ethnicities, aOR 1.79), an education level (no education, aOR 9.59; primary, aOR 3.50; secondary, aOR 1.70), occupation (private, aOR 2.16; self-employed, aOR 2.31; retirees, aOR 1.69; student, aOR 2.31; unpaid workers, aOA 2.35; not working, aOR 2.86), non-diabetes aOR 1.43, and low fruit and vegetable intake person aOR 1.86. Meanwhile, another 20.4% or an estimated 4.3 million adults who were ever heard of Malaysian Healthy Plate. Among those who are ever heard, 80.8% (3.5 million) correctly interpreted or understood the concept and among those who ever heard and understood the concept, only 70.5% (2.5 million) have been practising it daily or occasionally.
CONCLUSIONS: Four-fifth of adults never heard of the 'Malaysian Healthy Plate' and among those who ever heard, the understanding and practising of the concept were probably unsatisfactory. Multisectoral collaboration is an urge to fasten the promotion to spark awareness and educate the public to practice the concept to promote healthy eating and a healthier nation.
METHODS AND ANTICIPATED RESULTS: A cluster randomized controlled study will be conducted, involving 250 Middle Eastern adolescents, in Arabic schools in Malaysia. The participants will be randomly assigned to the intervention and control groups. While the intervention group participates in six weeks of fortnightly six sessions (45 minutes per session), the control group will carry on with their regular curriculums, and normal physical activity routines. The variables which will be evaluated include anthropometric measurements, knowledge, attitude, daily routines, physical activity, sedentary behaviour, food assessment, eating attitudes test-26, and a structured questionnaire based on the HBM. Data will be collected from the intervention and control groups at baseline, post-intervention, and two months following the intervention. Data analysis will be performed by way of the SPSS Statistics software version 26. The generalized estimating equation (GEE) will be used, to test the effect of the intervention program, with regards to the selected variables (outcomes), between and within-group at baseline, as well as six weeks and two months following intervention, after adjusting for clustering. Outcomes will be assessed at each time point, along with a derived average over all three-time points; thus, ensuring that both the cumulative and overall effects are determined.
CONCLUSIONS: This trial will provide useful information for improving the knowledge, attitude, and practices of Middle Eastern adolescents, with regards to body weight status, physical activity level, nutrition status (BMI and dietary intake), and disordered eating. This will go a long way, towards ensuring their adherence to appropriate physical activities, and a healthy diet, to keep non-communicable diseases at bay.
TRIAL REGISTRATION: This study is registered at NCT: NCT05694143.
SUBJECTS/METHODS: The height, weight, and WC of four-hundred-and-ninety adults (n = 490) in Malaysia were measured using standard procedures. The three-day 24-hour dietary recalls were conducted on 422 out of the 490 adults and their dietary intakes were evaluated in detail. The selected dietary intake variables were used to determine the associations with the obesity indicators.
RESULTS: Among the participants, 52.8% were overweight or obese. After data analysis, the mean energy intake was 1,550 kcal/day, in which male participants had a significantly higher energy and macronutrients intake than females. Protein consumption and its percentage of energy contribution exceeded the recommended range. The consumption of fruits, vegetables, and milk and milk products were lower than the recommended number of servings for a healthy diet. The male participants consumed significantly more servings of carbohydrate-based foods, meat, and fats, oils, and sweets than females. Among the selected dietary intake variables, only the carbohydrate intake was negatively associated with the BMI (Estimate b = -0.008) and WC measurements (Estimate b = -0.019) after adjusting for covariates.
CONCLUSIONS: This study evaluated the dietary intakes of a sample of Malaysian adults and its association with the obesity indicators. The results highlight the need for improvements and modifications of the dietary intake of Malaysians to reduce the overweight and obesity rates.
OBJECTIVE: This study assessed the diet quality of households by their type of engagement in homestead aquaculture and/or horticulture. Socio-demographic determinants of diet quality were also studied.
METHOD: Diet quality was assessed using a nutrient adequacy ratio (NAR), based on the preceding 7 days' dietary recall at the household level. Adult male equivalent units (AMEs) were used for age- and sex-specific intra-household distribution of household intakes. Mean adequacy ratios (MAR) were computed as an overall measure of diet quality, using NAR.
RESULTS: Better diet quality (mean ± SD) was associated with households engaged in both homestead aquaculture and horticulture (0.43 ± 0.23; p < 0.001) compared to only one type of agriculture (0.38 ± 0.20) or none (0.36 ± 0.20). Tukey's post-hoc test confirmed significant differences in diet quality between both and either engagement (0.05 ± 0.01, p < 0.001), both and no engagement (0.07 ± 0.01, p < 0.001), and either and no engagement households (0.02 ± 0.01, p < 0.001). Beyond farm production of nutrient-rich foods, generalized estimating equations showed that diet quality was influenced by the higher educational level and occupation of adult household members, higher daily per capita food expenditure, sex, family size and region.
CONCLUSIONS: Projects that promote and support household engagement in both homestead aquaculture and horticulture have the potential to improve the diet quality of households.
