Introduction: Monitoring changes in energy and nutrient intakes of the population
over the course of time is essential to help healthcare providers develop effective
dietary policies. The aim of this study was to assess the changes in the nutrient
intake and Recommended Nutrient Intake (RNI) achievements by using the data
obtained from the Malaysian Adult Nutrition Surveys (MANS) that were carried out
in 2003 and 2014. Mis-reporting of energy intake was taken into account. Methods:
Dietary data were obtained from MANS 2003 and MANS 2014, which involved a
combined total of 4,044 randomly selected respondents, aged 18-59 years, using
a single 24-hour diet recall. Energy and nutrients calculations were based on the
Malaysian Food Composition database using the Nutritionist Pro software. The
results were compared against the RNI for Malaysia to assess dietary adequacy.
Results: The proportions of calories derived from macronutrients were within the
recommendations for a healthy diet. The consumption of protein, fat, calcium, iron
and vitamin A was significantly higher in 2014 than in 2003. The consumption
of protein, iron, vitamin C, and vitamin A was found to exceed the RNIs in 2014.
However, carbohydrate and sodium intakes had significantly decreased. Despite the
decrease, sodium intake still exceeded RNI recommendations. Conclusion: Signs
of changing energy and nutrient intakes were found, including increases in protein
and fat intakes since 2003, and decreased carbohydrates. This could be an alarming
indicator of the tendency to eat energy dense food among the population.
Introduction: Under-reporting of energy intake is a common cause of bias
in nutritional studies. This study was aimed at examining the extent of underreporting of energy intake and its related characteristics among respondents in
the Malaysian Adult Nutrition Survey (MANS) 2003 and MANS 2014. Methods:
The present study analysed energy intakes of 9,624 adults aged 18-59 years from
the MANS in year 2014 (2,890 respondents) and 2003 (6,734 respondents) using
a single 24-hour diet recall. Basal metabolic rates (BMR) were calculated from the
age- and gender-specific equations of Schofield. Under-reporting was defined as an
energy intake:BMR ratio of
Interventions to counter the influence of television food advertising amongst children are important. Thus, reliable and valid instrument to assess its effect is needed. The objective of this study was to determine the reliability and validity of such a questionnaire. The questionnaire was administered twice on 32 primary schoolchildren aged 10-11 years in Selangor, Malaysia. The interval between the first and second administration was 2 weeks. Test-retest method was used to examine the reliability of the questionnaire. Intra-rater reliability was determined by kappa coefficient and internal consistency by Cronbach's alpha coefficient. Construct validity was evaluated using factor analysis. The test-retest correlation showed moderate-to-high reliability for all scores (r = 0.40*, p = 0.02 to r = 0.95**, p = 0.00), with one exception, consumption of fast foods (r = 0.24, p = 0.20). Kappa coefficient showed acceptable-to-strong intra-rater reliability (K = 0.40-0.92), except for two items under knowledge on television food advertising (K = 0.26 and K = 0.21) and one item under preference for healthier foods (K = 0.33). Cronbach's alpha coefficient indicated acceptable internal consistency for all scores (0.45-0.60). After deleting two items under Consumption of Commonly Advertised Food, the items showed moderate-to-high loading (0.52, 0.84, 0.42 and 0.42) with the Scree plot showing that there was only one factor. The Kaiser-Meyer-Olkin was 0.60, showing that the sample was adequate for factor analysis. The questionnaire on television food advertising is reliable and valid to assess the effect of media literacy education on television food advertising on schoolchildren.
Introduction Overweight and obesity is a major public health problem in Malaysia. This study aims to determine the prevalence of overweight and obesity among the Malaysian adult population and their association with socio-demographic characteristics (gender, ethnic, and age groups).
Methods A total of 17,257 adults aged 18 years and older (8,252 men, 9,005 women)
were assessed for BMI status, with a response rate of 97.8%, through a household survey from the National Health and Morbidity Survey (NHMS), conducted in all states of Malaysia in 2011.
Results All socio-demographic factors were consistently associated with higher chance of being overweight (except gender and location) and obesity (except location and household income). The identified risk of overweight were
Indian (aOR: 1.8, 95% CI: 1.2-2.8), aged 50-59 years (aOR: 2.8, 95% CI: 2.0-3.9), widower (aOR: 1.6, 95% CI: 1.3-2.0), subject with secondary education (aOR: 1.2, 95% CI: 1.0-1.4), Homemaker/unpaid worker (aOR:
1.3, 95% CI: 1.1-1.4), and with high household income group (aOR: 1.3, 95% CI: 1.2-1.6). The identified risk of obesity were women (aOR: 1.4, 95% CI: 1.2-1.6), Indian (aOR: 1.7, 95% CI: 0.9-3.2), aged 30-39 years (aOR: 3.6,
95% CI: 2.4-5.5), widower (aOR: 1.2, 95% CI: 0.9-1.6), subjects with primary education (aOR: 1.2, 95% CI: 0.9-1.6), Homemaker/unpaid worker (aOR: 1.3, 95% CI: 1.1-1.6), and with middle household income group (aOR: 1.3, 95% CI: 1.2-1.6).
Conclusions Our data indicate a high prevalence of overweight and obesity in the
population. Several sociodemographic characteristics are associated with both overweight and obesity. This study highlights the serious problem ofoverweight and obesity among Malaysia adults. Documentation of these problems may lead to research and policy agendas that will contribute both to our understanding and to the reduction of these problems.
