Psychosocial predictors of adherence to nutritional recommendations and growth outcomes in children with cystic fibrosis

This study aimed to elucidate the relationship between maternal psychosocia l factors related to dietary adherence and growth outcomes in their childre n with cystic fibrosis (CF). Twenty-five children with CF and mild lung dis ease, aged 7-12 years, were weighed and measured and completed detailed foo d records. Mothers completed questionnaires that measured general nutrition al knowledge, nutritional knowledge specific to CF, coping strategies, diet ing behaviors, self-efficacy about the ability to provide the correct diet, and attitudes and beliefs about CF. Of the cohort, only 16% adhered to the dietary recommendations. Dietary adherence was positively correlated with weight. Maternal nutritional knowledge specific to CF significantly predict ed children's dietary adherence score. There was a significant negative cor relation between the child's weight and mothers who were dieting successful ly. Other psychosocial factors assessed were not related to dietary adheren ce. Improving the mother's knowledge about nutritional needs in CF appears worthwhile and may have an impact on growth. (C) 1999 Elsevier Science Inc.
