Children with cystic fibrosis (CF) typically have similar nutritional intake as healthy peers, despite recommendations to consume more calories and fat. Body satisfaction may play a role in nutritional intake: females may be content with their smaller size despite recommendations for weight gain, while males may desire to be larger and more muscular, which is more congruent with medical advice. Females are especially at risk, given their propensity to desire a smaller body size, tendency for lower HRQOL, steeper trajectory of health decline and shorter life expectancy than males. This study evaluated body satisfaction in relation to nutritional adherence and HRQOL in youth with CF. Fifty-four individuals with CF (age 9-17) completed the Cystic Fibrosis Questionnaire-Revised (CFQ-R), the Figure Rating Scale, and a 24-hr diet recall interview with their caregiver. Twenty-four percent of youth were non-adherent with caloric goals, and 40.7% did not obtain the minimum recommendation for fat intake. Youth were classified as inconsistent with treatment goals (TI) if they desired a smaller body size or were content with their current size despite a BMI less than the 50th percentile; 44.8% of females were classified as TI, compared to only 8% of males. Statistical analyses were performed to evaluate the impact of gender and body satisfaction on HRQOL in youth with CF. Linear multiple regression models were fit; TI females had Emotional HRQOL scores 23 points lower than males. Results suggest that improving body satisfaction, especially for females, may help to improve overall quality of life and potentially impact nutritional adherence.
