Introduction: Skipping breakfast may contribute to poor academic and nutritional status among school children. The current study aimed to determine the effect of the ‘MAPAGI’ (Makan Pagi Bergizi) interactive video game on elementary student’s breakfast knowledge and attitude. Methods: This was a quasi-experimental equivalent group study with a pre-post test control group design. In total, 228 students aged 9-11 years were drawn by proportional stratified random sampling from two urban schools and were distributed equally into intervention (IG) and control groups (CG). Both groups were administered with similar printed media for 10-15 minutes. Video game was delivered only to IG for two consecutive days, 30 minutes each day. Pre-test (PT0) was performed a day before leaflet administration, while post-test was performed twice – after leaflet administration (post-test 1/ PT1) and a week after the last video game (post-test 2/PT2). Paired, independent t-test and analysis of covariance (ANCOVA) were employed to answer the research questions. Results: The mean changes (PT1-PT0 and PT2-PT0) in knowledge score for IG (4.82±2.53 and 3.25±2.47) significantly differed compared to CG (1.75±2.66 and 1.25±2.69). The mean changes in attitude score for IG (7.16±7.17 and 7.34±7.11) also significantly differed compared to CG (2.83±6.58 and 2.64±6.90). After adjustment for potential confounding factors, there was still a significantly greater score in children’s knowledge and attitude after a week’s administration of MAPAGI video game in IG. Conclusion: ‘MAPAGI’ improved school children’s knowledge and attitude, which may lead to the good behaviour of having breakfast.

Introduction: In Indonesia, anaemia is known to be extremely common in female adolescents. In addition, the problem of overweight/obesity in teenagers is becoming more prevalent, even in stunting locus areas. This study aimed to examine the correlation between body mass index (BMI) and haemoglobin levels among adolescent girls in Tangerang’s stunting locus area. Methods: This crosssectional study included 171 adolescent girls attending four junior and senior high schools in Tangerang’s stunting locus area. Adolescents who matched the inclusion criteria— healthy, having lived in Sukamantri for more than six months, and willing to participate were chosen by a multistage cluster sampling procedure. Body weight and fat were measured, and Z-score for BMI-for-age was determined. Haemoglobin levels were measured by the Mission Hb Testing System. Multiple linear regression test was applied for the analysis. Results: The prevalences of thinness/severe thinness, normal, and overweight/obesity were 5.3%, 70.8%, and 23.9%, respectively. There were 20% of anaemic girls. Among anaemic girls, there were 26% overweight/obese and no thin/very thin girls. A weak, negative correlation between BMI with haemoglobin levels was observed (R2=0.054, p<0.001). Conclusion: The correlation between BMI and haemoglobin level was weak in our sample of adolescent girls in the stunting locus area. The current study emphasised the importance of additional research that includes several haematological and inflammatory biomarkers to better understand the complex relationship between nutritional status and haemoglobin level.
