This study examined the effectiveness of a 7-session (9 week) behavioral intervention aimed at increasing caloric intake on dietary calcium (Ca) intake in children with cystic fibrosis (CF). Diet diaries collected 2 weeks before and 2 weeks after treatment were reanalyzed for Ca intake in 44 children with CF ages 3 to 12 years of age. Paired t test analysis revealed a significant increase in mean daily dietary Ca pre- (1,006 mg/Ca/day) to posttreatment (1,467 mg/Ca/day), t(43) = 6.56, p < .001. Follow-up data on 15 participants demonstrated maintenance of these gains 12 months after treatment. Behavioral interventions appear promising for increasing dietary Ca intake in children with CF.
