title: One-year follow-up of quality of life in adults with untreated growth hormone deficiency.
abstract: OBJECTIVE
  The aim of the study was to evaluate the impact on health-related quality of life (HRQoL) in untreated GHD patients using the disease-specific Assessment of Growth Hormone Deficiency in Adults (AGHDA) questionnaire.
  
  
  METHODS
  A cohort of 356 consecutive adult GHD patients, diagnosed after the age of 18 years, from the endocrinology units of 37 Spanish hospitals were included over a 6-month period in a longitudinal observational quality-of-life study. In addition, patients' HRQoL scores were compared to those obtained from a random sample of 963 subjects from the general population recruited by trained interviewers in a 6-month period and matched by age and sex to figures of the 1991 Spanish census.
  
  
  METHODS
  Patients were evaluated at baseline and after 12-months. Socio-demographic and health variables such as age, sex, level of education, income level, number of chronic diseases and self-reported health status were recorded at baseline and follow-up visits. Patients underwent physical and analytical examination and completed the AGHDA questionnaire. A survey including socio-demographic, self-reported health status and the AGHDA questionnaire was administered at the individuals' homes.
  
  
  RESULTS
  Mean score for patients at baseline was 9.4 (CI = 8.4-10.4) and at 12 months 10 (CI = 8.8-11). HRQoL was worse in the case of older patients with a low level of education, lower income levels, reporting having an associated chronic disease and poor self-reported health status (P < 0.01). Untreated GHD patients maintain or slightly worsen their HRQoL after 12 months of follow-up, with high individual variability. Although AGHDA scores worsened during the observation period, differences were not statistically significant. AGHDA mean score in controls was 5.49 (CI = 5.27-5.71). Comparison of the mean AGHDA scores between patients and controls previously standardized by level of education and age were statistically different (P < 0.01), indicating that patients declared a worse HRQoL than the general population except for those aged 60-69 years. GHD patients presented a deterioration in HRQoL almost double that of the general population.
  
  
  CONCLUSIONS
  These results permit comparison of patients' scores against reference scores with regard to the desirable effect of treatment. Future use of the AGHDA questionnaire in clinical trials should try to establish a relationship between biological and HRQoL changes.
