Assessment of parents´ knowledge regarding phenylketonuria and its affecting factors: a cross-sectional study.

INTRODUCTION

the management of phenylketonuria (PKU) is complex. Practical skills and knowledge of individuals taking care of PKU patients are important for treatment compliance. This study investigated parents´ knowledge about PKU and its affecting factors. The study group consisted of 62 parents of PKU patients.

METHODS

data were collected using a ready-made questionnaire on sociodemographic characteristics, PKU and dietary treatment. Total knowledge score (KS) was calculated by giving 5 points for each correct answer.

RESULTS

the study included 34 mothers and 28 fathers; 90.3% of patients were diagnosed during the newborn screening program, 6.5% between ages 1 and 2, and 3.2% at age 6 or after. Among all, 38.7% presented to their follow-up appointments with their mothers, 61.3% with both their parents and none with their father alone. Mothers answered all questions more accurately than fathers. Mothers´ and fathers´ mean KSs were 73.97 ± 12.72 and 53.04 ± 22.25, respectively. The highest KS was obtained among parents whose children were 13 years of age or older.

CONCLUSION

the presence of another family member, parents´ education level, working status and professional qualifications, previous training on PKU and family´s economic status were the affecting factors. Creating a PKU dietary plan requires knowledge and diligence. Patients and their parents should be periodically informed about the disease and dietary treatment in order to increase their level of knowledge.
