My Body is Fit and Fabulous at School Phase II

To see changes in BMI z-score. Also called as BMI standard deviation scores, which measures relative weight adjusted for child age and sex. Weight in kilograms and height in meters will be combined to report BMI in kg/m^2. By using the value of BMI obtained, BMI z-score was calculated using World Health Organization (WHO) AnthroPlus 2007 software, with indication of overweight >+1.0 SD, obese >+2.0 SD and morbidly obese >+3.0 SD.

To see changes in percentage of body fat. It is the percentage of body weight that is made up of fat. It consists of both storage body fat and essential body fat. It was measured in light clothing without shoes and socks to the nearest 0.1 kg using a pre-calibrated body impedance analyser (InBody 770, Korea)

To see changes in Waist Circumference. Waist Circumference was measured twice to the nearest 0.1 cm over the skin midway between the tenth rib and the iliac crest at the end of normal expiration, using a non-extensible tape.

To see changes in Skeletal Muscle Mass. Skeletal Muscle Mass is the weight of muscles that connected to the bones in the body that were measured in light clothing without shoes and socks to the nearest 0.1 kg using a pre-calibrated body impedance analyser (InBody 770, Korea)

To see changes in HbA1c Level. HbA1c level was determined by cationic exchanged high performance liquid chromatography (Adams A1c HA-8160, Arkray Inc, Japan) and followed the National Glycohemoglobin Standardization Programme Guidelines.

To see changes in Fasting Plasma Glucose. Fasting Plasma Glucose was analysed by Randox Laboratories (Antrim, UK) using an auto chemical analyser (Dirui CS-400, China).

To see changes in Total Cholesterol. Total Cholesterol was analysed by Randox Laboratories (Antrim, UK) using an auto chemical analyser (Dirui CS-400, China). The cut-off value for high Total Cholesterol is 5.20 mmol/L.

To see changes in Triglycerides Level. Triglycerides Level was analysed by Randox Laboratories (Antrim, UK) using an auto chemical analyser (Dirui CS-400, China). The cut-off value for high Triglycerides Level is 1.70 mmol/L.

To see changes in HDL-C Level. HDL-C Level was analysed by Randox Laboratories (Antrim, UK) using an auto chemical analyser (Dirui CS-400, China). The cut-off value for low HDL-C Level is 1.03 mmol/L.

To see changes in LDL-C Level. LDL-C Level was analysed by Randox Laboratories (Antrim, UK) using an auto chemical analyser (Dirui CS-400, China). The cut-off value for high LDL-C Level is 2.84 mmol/L.

To see changes in Fasting Insulin Level. Fasting Insulin levels were measured using an automated enzyme immunoassay analyser (TOSOH AIA-360, Japan).

To see changes in HOMA-IR. HOMA-IR is calculated by multiplying the value of fasting insulin and fasting plasma glucose and divided by 22.5.

To see changes in TG:HDL-C Ratio. TG:HDL-C Ratio is calculated by dividing triglycerides levels with HDL-C levels.

To see changes in Physical Fitness Score. Physical Fitness Score was assessed using Modified Harvard Step Test. Physical Fitness Score was calculated with this formula: (Total duration in seconds/Total pulse rate at 0, 1 and 2 minutes) X 100. After the calculation of the physical fitness score, the subjects' physical fitness were categorized into 5 different categories. The first category was poor, where the score of their physical fitness score is below 54. The second was low average, as their physical fitness score falls between the range of 55 to 64. Next, high average with the score between 65 to 79 followed by the fourth category which was good i.e. between the ranges of 80 to 89. Lastly, the fifth category was excellent, where the subjects' physical fitness score were more than 90.

To assess their changes of Nutrition Knowledge using a pre-tested Nutrition Knowledge using a validated Nutrition Knowledge Questionnaire. The school children completed a 10-item True/ False/ Don't know Nutrition Knowledge questionnaire before and after intervention. The correct answer was given a score of 1 whereas for the wrong answer and I don't know was given a score of 0. The total score for every respondent was calculated from the correct responses with a maximum of 10 points which were then converted to percentages. Total scores for the knowledge items were then ranked into 3 tertiles; lowest (≤50%), middle (60%) and highest (70-100%).

To assess their changes of Nutrition Attitude using a pre-tested Nutrition Attitude Questionnaire. There were 15 questions for the attitude items. The attitude items were on a five-point Likert scale ranging from strongly disagree (1 point) to strongly agree (5 points). An intermediate (neutral) option was allocated 3 points. Total scores for the attitude items were then ranked into 3 tertiles; lowest (≤50%), middle (60%) and highest (70-100%).

To assess their changes of Nutrition Practice using a pre-tested Nutrition Practice Questionnaire. Assessment focused mainly on the key components that should be and commonly practiced by the school children. These included intake of fruit and vegetable, plain water, carbonated drinks, breakfast intake a swell as food commonly brought food from home and also food commonly purchased from the school canteen.

To assess their behavioural changes via Stage of Change of Weight Management by using a validated Trans Theoretical Model Questionnaire for weight management behaviour.

To assess their behavioural changes via Stage of Change of Fruit and Vegetable Intake by using a validated Trans Theoretical Model Questionnaire for fruit and vegetable intake behaviour.

To assess their changes of Health-Related Quality of Life using KINDL-R questionnaire. It contains 24 Likert-scaled items that are associated with 6 subscales namely physical well-being, emotional well-being, self-esteem, friend, family and school functioning. Total scores are obtained by adding the scores of all subscales. Higher scores represent better outcome. Range score from 15 to 75

To assess their changes of Well-Being using the Stirling Children Well-being Scale (SCWBS) questionnaire. It is comprised of two subscales which are positive outlook and positive emotional state. Total scores are obtained by adding the scores of all subscales. Higher scores represent better outcome. Range score from 24 to 120
