Introduction: Child malnutrition continues to be a major public health problem in developing countries. This study aims to determine the current nutritional status of Malaysian school children using the anthropometric indicators of weight for age (WAZ), height for age (HAZ), and body mass index for age (BAZ). Methods: A nationwide school-based survey was undertaken in all Malaysian
states and territories, which included 18,078 children aged 8-10 years attending 445 primary schools. The software WHO AnthroPlus was used to calculate zscores for the nutritional status (WAZ, HAZ and BAZ) of the target population relative to the World Health Organization (WHO) 2007 reference. Results: The national prevalence of underweight among school children was 13.6% and in
rural areas, this rate was nearly double that of urban areas. The national prevalence rate for stunting was 10.9%, double among rural school children compared to their urban counterparts. As for thinness, the national prevalence was 6.5%. Using the WAZ indicator, we found that the national prevalence of overweight children was 7.6%. Additionally, we found that urban areas showed a higher
prevalence of overweight children (8.8%) than rural areas (5.9%). Conclusion: The findings of this study indicate that Malaysian school children face the burden of malnutrition, suffering from both undernourishment and overweight. Malaysia must make a concerted effort to overcome the problems of malnutrition among children.
Introduction Physical activity assessment in children is the first step in assessing the
relationship between activity and health, as well as the determinants of
childhood physical activity and changes in activity level.Physical Activity
Questionnaire for Older Children (PAQ-C) is self- administered
questionnaire to assess physical activity among older children. The objective
of this study was to determine the validity and reliability of Physical Activity
Questionnaire for Older Children in Malay language PAQ-C (M).
Methods The validation study was done among 73 students aged 10 to 17 years old.
The PAQ-C was translated into Malay language using forward and backward
translation. The evaluation of the psychometric properties included internal
consistency, test-retest reliability and criterion validity. Reliability of PAQ-C
(M) was determined using Cronbach alpha and intra-class correlation
coefficient (ICC). The PAQ-C (M) was administered twice in one week
interval to assess test-retest reliability. Criterion validity was assessed
between PAQ-C (M) and 3 Day Physical Activity Recall (3DPAR).
Results The internal consistency of PAQ-C (M) assessment calculated in this study
was α = 0.75 and α = 0.77 for assessments one and two, respectively. The
ICC between individual items of PAQ-C (M) was 0.59 to 0.91, indicating
moderate to good correlation. The Spearmen correlation coefficient between
PAQ-C (M) and 3DPARwas acceptable (r=0.60, p
There are several methods available for assessment of sodium intake, including dietary and urinary excretion, which are fraught with methodological difficulties. Therefore, the aim of this study was to validate dietary and urinary excretion methods against 24-hour urinary excretion method in estimating sodium intake in Malaysian adults. A cross-sectional study has been carried out between November to December 2015. About 1568 adults aged 18 to 59 years old have participated from 16 study sites located in the 13 states and two federal territories of Malaysia. The study collected basic socio-demographic data and habitual dietary intake by Food Frequency Questionnaire (FFQ). Respondents were also asked to complete a two-day food intake diary (2FD) and collect their 24-hours urine and spot urine using standard protocols. A total of 1116 adults successfully completed the survey, yielding a response rate of 71%. Sodium intake from 24-hour urine excretion was estimated at 2585.9mg/day which is above the recommendation by World Health Organization (WHO). The 2FD showed the nearest mean estimate to the reference method but the spot urine with Tanaka’s predictive equation showed the least bias. The estimation of sodium from spot urine alone or with Kawasaki’s predictive equation and FFQ method showed poor mean estimates and a large bias compared to the reference method. The 2FD and spot urine with Tanaka’s prediction equation can be good alternatives for estimating daily sodium intake at the population level but not at the individual level.
This study sought to examine the reliability and validity of height measurements using a portable
stadiometer as compared to a mechanical scale. Samples from 142 adults aged 22 to 57 were taken during data collection in November 2014. There was a high degree of reliability for the inter-examiner, intraexaminer and inter-instrument aspects with regards to mean difference, the inter correlation coefficient (ICC) and Bland-Altman Plot. For the inter-examiner aspect, the height measurement taken by the first examiner was 0.01 cm higher than that by the second examiner with an ICC of 0.999. For the intraexaminer aspect, the difference was 0.1 cm; this was higher in the first measurement compared to the second. The ICC was also 0.999. For the inter-instrument aspect, measurement taken by stadiometer was 0.61 cm higher than the measurement taken by mechanical scale and the ICC was 0.997. The Bland-Altman plot showed a distribution of differences between measurements in the inter-examiner, intraexaminer and inter-instrument aspects that were close to zero within the narrow range of ±1.96SD. The technical error of measurement (TEM), coefficient of reliability (R) and coefficient of variation (CV) for the inter-examiner, intra-examiner and inter-instrument aspects were within the acceptable limits. This study suggests that the portable stadiometer is reliable and valid for use in community surveys.
Introduction: Changes in dietary habits are known to be associated with changes in health outcomes. This study determined food choices among Malaysian adults using secondary data of the Malaysian Adults Nutrition Survey (MANS) in 2003 and MANS in 2014.
Methods: A total of 6,742 and 3,000 adults aged 18 to 59 years participated in MANS 2003 and MANS 2014, respectively. Both studies used a semi-quantitative food frequency questionnaire (FFQ) to assess habitual food intake.
Results: Overall, the prevalence of adults consuming rice twice daily were 97.3% and 86.9% in 2003 and 2014, respectively. While the percentage of urban dwellers who consumed rice daily differed significantly between 2003 (96.7%) and 2014 (86.9%), the percentage remained quite similar among rural adults in 2003 (97.8%) and 2014 (96.3%). Other top ten food items consumed daily were sugar (2003, 58.5% vs 2014, 55.9%), marine fish (40.8% vs 29.4%), green leafy vegetables (39.9% vs 43.2%) and sweetened condensed milk (35.2% vs 29.3%). In both surveys, a higher percentage of men consumed rice, sugar and sweetened condensed milk on a daily basis compared to women, a higher proportion of whom daily consumed green leafy vegetables and marine fish. Majority of the adults reported drinking plain water daily. Other beverages taken daily were tea, coffee and chocolate-malt drinks.
Conclusion: Rice, sugar and sweetened condensed milk were among the top food items consumed daily in 2003 and 2014. Educational efforts to improve dietary intake of Malaysian adults is recommended.
Study name: Malaysian Adult Nutrition Survey (MANS-2003); Malaysian Adult Nutrition Survey (MANS-2014)
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.
Study name: National Health and Morbidity Survey (NHMS-2011)
Erectile dysfunction (ED) is a pervasive problem among men, often shrouded in silence and stigma. This manuscript analysed the National Health and Morbidity Survey 2019 data to identify the prevalence of moderate to severe ED among men aged 18 and above in Malaysia and describe its associated factors. Self-administered questionnaire on ED utilised a locally validated International Index of Erectile Function. Variables on sociodemographics, risky lifestyles and comorbidities were obtained via an interviewer-administered questionnaire. The prevalence was determined using complex sampling analysis, and logistic regression was used to determine the associated factors of ED. A sample of 2403 men aged ≥ 18 participated, with a moderate to severe ED prevalence was 31.6% (95% CI 28.8, 34.6). The mean (± SD) of the total score of IIEF-5 for overall respondents was 18.16 (± 4.13). Multiple logistic regression analysis revealed a significant association between moderate to severe ED among men aged 60 years and above, single or divorcee, men without formal, primary, and secondary education, non-government employees, unemployed, and retiree, as well as physically inactive men. Focused public health interventions are necessary to improve education in sexual health, increase health promotion programs, and promote healthy ageing across the population.
