title: The impact of age and BMI on impairment due to disordered eating in a large female community sample.
abstract: The impact of age and BMI on functional impairment in eating disorders was assessed by the Clinical Impairment Assessment (CIA) scale in a representative community sample. The CIA was administered to 1080 women aged 16-50 years (M=36.2, SD=9.5) with a range of BMI from 13.5 to 55.0 (M=24.6, SD=4.9) randomly selected from the Norwegian National Population Register. The average global CIA score was 5.3 (SD=8.5). Impairment tended to decrease with age (r(s)=-.20, p<.01), yet increased with greater BMI (r(s)=.31, p<.01). Approximately 30% of the participants with obesity scored in the clinical range compared to 7% of the underweight and normal-weight participants. Data supported the utility and feasibility of the CIA as a measure of functional impairment secondary to weight, shape, and eating concerns. It is recommended that age and BMI be considered during the interpretation of CIA data.
