(1) Background: One of the most main dietary assessments is through a posteriori application. Although extensive research has incorporated dietary assessment of a population through a posteriori application, this study is the first to examine the Malaysian population and use an a posteriori method and principal component analysis (PCA) to assess the dietary patterns of the Malaysian population. The correlation between all dietary patterns derived via PCA and selected nutrient intake were determined in this sample of study; (2) Methods: A total of 3063 respondents (18 to 59 years old) covering Peninsular Malaysia, Sabah, and Sarawak, participated in this study. PCA was applied on the food frequency questionnaire collected from the respondents, and descriptive statistics and PCA were performed using SPSS version 21; (3) Results: Six patterns were identified: “traditional”, “ prudent”, “ modern”, “western”, “Chinese”, and “combination” diets. All together, these six patterns were able to explain 45.9% of the total variability. Few components derived from the factor loadings showed positive association with several nutrient markers. The traditional dietary pattern showed a moderate, positive correlation with total protein and total sugar intake, there was a significant moderate correlation between the prudent dietary pattern and dietary fibre, and there was a moderate positive association between the Chinese dietary pattern and total energy; and (4) Conclusions: The exploration of the PCA approach above may provide justification for assessment of dietary patterns rather than reliance on single nutrients or foods to identify potential connections to overall nutritional wellbeing as well as to explore the diet–disease relationship. However, study of pattern analysis must be conducted among the Malaysian population to produce validity and reproducibility for this dietary approach in light of the numerous methodological issues that arise when performing PCA.

The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index–based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes.

In 2016, World Health Organization (WHO) estimated more than 650 million obese adults, resulting in a country’s health burden. This study aims to determine the prevalence of obesity and its associated factors among Malaysian adults. A total of 5820 respondents, aged 18 to 59 years, from the National Health and Morbidity Survey 2019, were included for the data analysis. The prevalence of obesity was described and multivariate analyses were conducted to determine the factors associated with obesity. The prevalence of obesity among Malaysian adults was 20.1%, based on the findings from this study. Multivariate analyses showed that women, being Malays, Indians, and other Bumiputeras, were significantly associated with a higher risk of obesity. Besides, those diagnosed with diabetes mellitus and hypertension were also significantly associated with greater risk of obesity. This information is crucial for policy makers in formulating effective strategies or targeted programs in preventing obesity among Malaysian adults.

Malaysian Healthy Plate was launched in 2017 as a vital component of the Malaysian Ministry of Health’s “Quarter-Quarter-Half” program. It is predicted that this concept will bring positive change to the citizen’s dietary habits; however, the residents in rural areas may experience less exposure to this campaign, or lack of understanding to the concept of Malaysian Healthy Plate. Hence, this study aims to assess factors affecting the campaign’s awareness among the rural population in Malaysia. The National Health and Morbidity Survey (NHMS) 2019 focused on Non-Communicable Diseases (NCDs). Data collection was carried out from July to September 2019. Questionnaires that pertained to awareness, knowledge, and practice were included in this nationwide survey. Data collected from adults in rural areas aged 18 years old and above were used as respondents for the statistical analysis. Complex sample multiple logistic regression analysis was conducted to determine the association between the independent variables and awareness of the Malaysian Healthy Plate concept. About four fifths (83.2%) of rural adults in Malaysia were unaware of the Malaysian Healthy Plate concept after three years of implementation. The unawareness was significantly higher in males (91.3%), adults aged above 60 years old (91.8%), adults of others ethnicity (88.5%), those without formal education (95.2%), widows/widowers/divorcees (88.1%), retirees/adults who were not working (88.4%), and household income at the bottom 40% (B40) (85.0%). Unawareness of this concept was significantly associated with male gender (aOR = 4.12; 95% CI: 3.06–5.56); age, 40–59 years (aOR = 1.46; 95% CI:1.08–1.97); without formal education (aOR = 3.47; 95% CI:1.34–9.01); working in private sector (aOR = 2.75; 95% CI: 1.59–4.77); self-employed (aOR = 2.78; 95% CI: 1.58–4.87); retirees (aOR = 2.32; 95% CI: 1.23–4.36); and unpaid workers (aOR = 2.61; 95% CI: 1.51–4.51). Awareness of the Malaysian Healthy Plate concept is associated with rural adults being males, with older age, with lower socio-economic status, without partner, and without job. This study suggests that a more effective strategy is needed to increase the awareness of the Malaysian Healthy Plate concept among rural adults.

Introduction: Childhood obesity is a public health problem in Malaysia. Intake of sugar-sweetened beverages (SSB) is associated with obesity in children. There is a lack of studies on factors associated with SSB consumption in Malaysia. This study aimed to determine the sociodemographic factors associated with SSB consumption among Malaysian adolescents. Methods: Data of 2,021 students, aged 10-17 years on sociodemographic, SSB intake and anthropometrics were drawn from the school-based Adolescent Nutrition Survey 2017. A multistage stratified cluster sampling was used to obtain a nationally representative sample of primary and secondary school students. Body mass index (BMI)-for-age status was determined based on calculated z-score using the World Health Organization 2007 reference. SSB consumption was obtained from a food frequency questionnaire. Results: The prevalence of overweight and obesity among Malaysian adolescents were 16.6% and 14.7%, respectively. Malaysian adolescents consumed 1.4 cups of SSB per day. Rural children had a significantly higher SSB intake (1.5 cups) than urban (1.3 cups) children, while males (1.5 cups) had a significantly higher intake than females (1.3 cups). There were no significant differences in SSB consumption between thin, normal, overweight and obese adolescents. Conclusion: Almost all Malaysian adolescents consumed SSB during one month prior to the survey and the average amount consumed was 1.4 cups per day. Rural locality and male were associated with higher SSB consumption. There were differences in SSB consumption between Chinese and Malays, between Chinese and Indians, and between Chinese and Bumiputra Sarawak. There were no differences in consumption between the different BMI-for-age categories.
