Introduction Food labeling regulation has been implemented to enable consumers, including those with chronic diseases to make healthy informed choices before purchasing pre-packaged foods. The purpose of this study is to determine the prevalence of obese adults in Malaysia who practice reading food labels. It explored types of labels read and understanding of the information.
Methods Findings presented in this study were captured from the secondary analysis of National Health and Morbidity Survey’s (NHMS, 2006) food label study which focused only on obese adults (BMI > 30 kg/m2) aged 18 and above. This nation-wide cross sectional study was conducted from April to August 2006 using an interview-based questionnaire. Complex data analysis was done using Stata version 12.0.
Results There were 4565 obese respondents with the mean age of 33 ± 9.7 (18-60 years old). About 54.7% completed high-school and 9.9% were higher degree
holders. Prevalence of obese adults who claimed to read label was 80.5% (95%CI: 79.3, 81.6). Findings showed significant results in reading and understanding labels among all age group categories, Malay, Indian and other Bumiputras, all education categories and married respondents. Expiry date was the highest percentage being read (74.5%), followed by fat content (15.3%), vitamin (11.8%) and carbohydrate (10.9%).
Conclusions The obese population in Malaysia claimed to read and understand the food label but did not focus on specific macronutrients related to their health
condition. Findings can be used to implement effective education programmes targeting the relevant groups to instill an awareness to read, understand and use the label information as one of the means in combating obesity.

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.
