Adolygiad Systematig
Dywed yr awduron:
"This Cochrane review aimed to assess the effectiveness of the Health Promoting Schools (HPS) framework in improving the health and well‐being of students and their academic achievement."
Dywed yr awduron:
"The reviewers included 67 eligible cluster trials, randomising 1443 schools or districts. This is made up of 1345 schools and 98 districts. The studies tackled a range of health issues: physical activity (4), nutrition (12), physical activity and nutrition combined (18), bullying (7), tobacco (5), alcohol (2), sexual health (2), violence (2), mental health (2), hand‐washing (2), multiple risk behaviours (7), cycle‐helmet use (1), eating disorders (1), sun protection (1), and oral health (1). The quality of evidence overall was low to moderate as determined by the GRADE approach. 'Risk of bias' assessments identified methodological limitations, including heavy reliance on self‐reported data and high attrition rates for some studies. In addition, there was a lack of long‐term follow‐up data for most studies.
The reviewers found positive effects for some interventions for: body mass index, physical activity, physical fitness, fruit and vegetable intake, tobacco use, and being bullied. Intervention effects were generally small but have the potential to produce public health benefits at the population level. The reviewers found little evidence of effectiveness for standardised body mass index and no evidence of effectiveness for fat intake, alcohol use, drug use, mental health, violence and bullying others; however, only a small number of studies focused on these latter outcomes. It was not possible to meta‐analyse data on other health outcomes due to lack of data. Few studies provided details on adverse events or outcomes related to the interventions. In addition, few studies included any academic, attendance or school‐related outcomes. The reviewers therefore cannot draw any clear conclusions as to the effectiveness of this approach for improving academic achievement."
Dywed yr awduron:
"The authors conclude that the results of this review provide evidence for the effectiveness of some interventions based on the HPS framework for improving certain health outcomes but not others. More well‐designed research is required to establish the effectiveness of this approach for other health topics and academic achievement."
