Psychiatric treatment: A risk factor for obesity?

BACKGROUND

People with psychiatric diagnoses have increased physical health difficulties.

OBJECTIVE

To examine the physical growth parameters documented in children receiving psychiatric treatment.

METHODS

A chart review was performed on consecutive paediatric consultations in 1997 and 1998 on 34 children six to 12 years of age admitted to an intermediate-stay psychiatric inpatient service. Growth parameters of each child were plotted on standard growth curves. The prevalence of obesity (body mass index at or above the 95th percentile), absolute weight at or above the 95th and 50th percentiles, underweight status, tall and short stature, macrocephaly and microcephaly were calculated. The prevalence of atypical findings was compared with the expected prevalence of typical growth parameters in the general population. Risk factors for atypical growth parameters were recorded. An association between weight and specific medication use was explored.

RESULTS

It was found that 11.8% of the children were obese. It was also found that 23.5% of the children had weight at or above the 95th percentile, 79.3% had weight at or above the 50th percentile, 14.7% had macrocephaly and 79.4% had a head circumference above the 50th percentile; these results were statistically significant. The mean number of psychotropic medications prescribed was 6.4, although there was no significant association between higher weight and current medication type.

CONCLUSIONS

Children receiving inpatient psychiatric treatment were more likely to have higher weight than typical children. Monitoring growth parameters is an important component of the paediatric care of children with psychiatric diagnoses. Guidelines are required for obesity prevention and intervention in the context of the risk factors experienced by this high risk population.
