    Introduction: The increasing prevalence of adiposity is associated with the development of type 2 diabetes mellitus (T2DM). The two most popular methods to measure adiposity are body mass index (BMI) and waist-hip-ratio (WHR), which measure the overall and abdominal adiposity, respectively. The aim of this study was to determine whether BMI or WHR was more strongly associated with macronutrient intakes and lipid profiles in T2DM patients. Methods: In this cross-sectional study, a total of 210 T2DM patients, mean age of 56.73(SD 10.23) years, were recruited from Penang. Information on socio-demographic, body measurements (height, weight, waist circumference and hip circumference)and macronutrient intakes (three 24-hour dietary recalls) were recorded. Routine laboratory tests (fasting blood glucose, HbA1c, LDL, HDL, triglyceride and total cholesterol) were performed according to standard procedure. Results:Among the respondents, 84% had abdominal and 63% had overall adiposity respectively.There was a significant correlation between WHR and the total calorie(r=0.27; p

    Introduction: The consumption of ready-to-eat cereals (RTECs) has been associated with lower anthropometric status as well as a lower risk of childhood obesity. This relationship has not been investigated among school children in Malaysia. This study aimed to determine the association between consumption of RTECs and anthropometric status among primary school children in Kuala Lumpur. Method: In this cross-sectional study, a total of 208 school children aged 10 and 11 years were recruited from Kuala Lumpur, Malaysia. Information on socio-demographics, RTECs consumption and anthropometric measurements (height, weight and waist circumference) were obtained. Results: The overall median body mass index (BMI) and waist circumference (WC) were 17.95(IqR 6.45) kg/m2 and 57.35 (IqR 13.00) cm, respectively. The majority of the children (73%) consumed RTECs. The prevalence of obesity was 23.1%, with more boys (31%) than girls (17.4%) being obese. Meanwhile, 16.8% of the children were overweight. BMI (U=3335.50, z=-2.278, p=0.023) and WC (U=3273.50, z=-2.440, p=0.015) of those who consumed RTECs were significantly lower than those who did not consume RTECs. Meanwhile, children who did not consume RTECs were significantly more likely to develop abdominal adiposity than those who consumed RTECS, X2(2, N=208) =7.61, p=0.022. Conclusion: Children who consumed RTECs have significantly lower BMI and WC, as well as a lower chance of developing abdominal adiposity. Consumption of RTECs indicates an overall healthy lifestyle with an excellent nutritional profile to promote healthy body weight in children and decreased risk of childhood obesity.

    This study aimed to develop and validate whole grain KAP questionnaire among children. A
    guided self-administered questionnaire was developed. In this cross sectional study, a total
    of 207 children aged 9 to 11 years in Kuala Lumpur, Malaysia were recruited. Knowledge
    domain was considered as optimal level of difficulty and able to discriminate performance of
    good and poor children. Construct validity was assessed using exploratory factor analysis with
    principle components method and varimax rotation. Four factor-solutions emerged for attitude
    domain whereas 3 factor-solutions were constructed for practice domain. Internal consistency
    was acceptable for knowledge (KR20=0.70), attitude (CA=0.72) and practice (CA=0.73).
    Test-retest reliability intra-class correlation coefficients for knowledge, attitude and practice
    domains were 0.80, 0.78 and 0.79 (p
