An R, et al. - This systematic review aimed to investigate whether obesity could affect children's school attendance through its detrimental impact on their physical and mental health. In this meta-analysis, the clinicians found that among children with overweight and obesity, the odds of being absent from school was 27% and 54% higher than among their normal weight counterparts, respectively. Future studies were needed to adopt an experimental study design and accurate measures on school attendance and delineated the underlining pathways linking childhood obesity to school absenteeism through obesity-related illnesses and psychosocial problems.
