CONTEXT: Screening programs resulting in the early treatment of patients with
congenital hypothyroidism (CH) have successfully improved neurodevelopmental
outcome, but little is known about long-term health.
OBJECTIVES: The aim of the study was to assess health status, and socioeconomic
attainment, for a population-based registry of young adult patients.
DESIGN, SETTING, AND PARTICIPANTS: All 1748 eligible patients diagnosed during
the first decade after the introduction of neonatal screening in France were
invited to participate in this study at a median age of 23.4 yr. Completed
questionnaires were obtained from 1202 of the selected patients. The comparison
group included 5817 subjects from the last French Decennial Health Survey.
MAIN OUTCOME MEASURES: Health indicators including medical conditions, hearing
and visual status, sociodemographic characteristics, and quality of life were
RESULTS: Patients with CH were significantly more likely than their peers to
report associated chronic diseases (5.7 vs. 2.9%), hearing impairment (9.5 vs.
2.5%), visual problems (55.4 vs. 47.9%), and being overweight with a body mass
index of at least 25 kg/m(2) (22.8 vs. 15.7%) (P < 0.0001). Furthermore, fewer patients attained the highest socioeconomic category (14.6 vs. 23.1%) and were in full-time employment (39.9 vs. 44.8%) (P < 0.0001). They were more likely to still be living with their parents and had a lower health-related quality of life than their healthy peers, particularly for mental dimensions, with a mean difference for the mental summary component of 0.35 SD score (P < 0.0001). CH severity at diagnosis, treatment adequacy, and the presence of other chronic health conditions were the main determinants of educational achievement and health-related quality of life scores. CONCLUSION: These findings highlight the need for careful monitoring of neurosensory functioning, weight, and long-term treatment adequacy throughout childhood and adulthood.
