The studies showed that obese and overweight adolescents consume significantly more energy and macronutrients .
They are also more likely to skip their daily meals compared to their normal weight peers .
In most studies , the direction of the PA effect on body weight was unclear .
Some studies found that higher PA is associated with a lower risk of overweight and obesity .
Conclusions This review identified a lack of evidence and well-conducted prospect i ve studies on the effect of diet and PA on cardio-metabolic health of Malaysian adolescents
Background A sedentary lifestyle and an unhealthy diet are major factors in the increasing prevalence of obesity among Malaysian adolescents .
The purpose of this systematic review is to compile the evidence from observational and intervention studies among Malaysian adolescents to evaluate the associations between diet and physical activity ( PA ) as determinants of cardio-metabolic risk factors .
Physical activity, eating behaviour and body image perception among young adolescents in Kuantan, Pahang, Malaysia.
INTRODUCTION A cross-sectional study was conducted to determine physical activity , eating behaviour , body weight management knowledge , perception of body image and their association with  body weight status of adolescents . METHODS Respondents were 360 adolescents , aged between 13 to 14 years , from six r and omly selected secondary schools in Kuantan , Pahang . Physical  activity , eating behaviour , body weight management knowledge and perception of body image were measured by the  Physical Activity Question naire for Older Children ( PAQ-C ) , Eating Attitude Test-26 ( EAT-26 ) , Weight Management Knowledge Inventory ( WMKI ) and Contour Drawing Rating Scale ( CDRS ) , respectively . RESULTS Almost half of the respondents were categorised as having a normal BMI , while 30.3 % were severely thin and thin and 20.3 % were overweight and obese . Mean physical activity score was 2.06 + /- 0.45 with more males ( 35.0 % ) being physically active than females ( 17.3 % ) . Mean eating behaviour score was 15.41 + /- 10.37 , with 27.8 % of the respondents being at-risk for eating disorders . Mean weight management knowledge score was 5.35 + /- 1.80 , with more females ( 77.7 % ) having higher mean scores than males ( 42.3 % ) . Further , mean discrepancy score for body image perception was 1.24 + /- 0.99 , with 78.1 % of the respondents being dissatisfied with their current body size . Positive associations were found between eating behaviour ( r = 0.28 , p < 0.05 ) and body image ( r = 0.35 , p < 0.05 ) with BMI . Respondents with high eating behaviour scores and body image discrepancy scores were more likely to have greater BMI . CONCLUSION This study shows the need for healthy eating and body image intervention programmes to prevent overweight and obesity problems among adolescents
