The association between overweight and socio-economic status in children and adolescents is weak and not statistically significant.9 We speculate that obese children and adolescents have more physical and psychological complaints than healthy-weight individuals, causing them to visit their physicians more frequently. If they visit the practice more frequently, obese patients are more likely to be included in a survey of consecutive patients, thereby explaining the higher prevalences of obesity in primary care patients. Perhaps obese children or their parents are more worried about their health and therefore more likely to visit the physician for minor complaints. However, no association has been found between obesity and mental illness, although research regarding such an association is considered inconclusive at this time.10
Conclusions
The prevalences of obesity for children and adolescents presenting for care in Michigan primary care practices are higher than the state and national prevalences. Further studies using larger sample sizes, random sampling, and more settings are necessary to confirm or refute our findings. If this prevalence of obesity in primary care patients is confirmed, explanations for the differences should be explored.
