Pregnancy-related Health Behavior of Women with Congenital Heart Disease: Room for Behavioral Change Interventions

Adolescents' understanding of their congenital heart disease on transfer to adult-focused care

Adolescents with congenital heart disease (CHD) must take responsibility for their life and care. This requires that they have sufficient knowledge about their heart disease, treatment, and preventive measures. Thus, CHD-related education should be directed to adolescents. Research on adolescents' understanding and knowledge of CHD is limited. It is unknown what adolescents with CHD know about their heart defect, treatment, and preventive measures necessary to avoid complications. We addressed these questions in a descriptive cross-sectional study of 91 adolescents with CHD (53% males; median age 17 years). In the present study, we assessed the subjects' knowledge of CHD using the Leuven Knowledge Questionnaire for Congenital Heart Disease. The results showed that the patients had adequate knowledge (>80% correct answers) about the need for regular follow-up, their required diet, past treatment, and dental practices. They had moderate knowledge (50% to 80% correct answers) about the frequency of follow-up, occupational choices, medication regimen, and sexual activities. However, the patients had poor knowledge (<50% correct answers) of the name of their heart defect; the reasons for follow-up; the effects of competitive sports; the symptoms that reflect deterioration of their heart disease; the definition, characteristics, and risk factors of endocarditis; the possibility of recurrent episodes of endocarditis during their lifetime; the effect of smoking and alcohol on their heart disease; the hereditary nature of their condition; the suitability of intrauterine devices as contraceptives; the appropriateness of oral contraceptives; and the risks of pregnancy. In conclusion, the results of the present study have showed that the level of knowledge of adolescents with CHD has significant gaps.
