[Estimate of hypothyroidism prevalence in Lleida, Spain, based on thyroid hormone prescription]. / Estimación de la prevalencia de hipotiroidismo en lleida a partir de la prescripción de hormonas tiroideas.

BACKGROUND: Hypothyroidism is a common disease sometimes showing no specific symptoms, thus being difficult to diagnose. This study is aimed at estimating the prevalence of hypothyroidism in Lleida by way of thyroid hormone prescriptions and comparing the results with those from other regions. METHODS: A retrospective observational study. A total of 2,854 individuals undergoing thyroid hormone treatment through Social Insurance prescriptions. Moths of October-December 2001. VARIABLES: age, sex and healthcare region. RESULT: The prevalence of hypothyroidism for 2001 is 8.4 cases per 1000 inhabitants/day (IC 95%: 9.23-7.47). Average age: 60 (DS <:16.6). Age spread: 2.4@1000 among males and 12.4@1000 among females. By age groups: Under age 15:3., 6@1000, 15-64 age group, 6.8@1000 and those over age 64, 12.5@1000. The highest figures were found in the rural areas (Seu d'Urgell: 10.5@1000), and the lowest in urban areas (Example: 5.8@1000, Balafia: 5.4@1000) CONCLUSIONS: Hypothyroidism under treatment figure is, as in other studies, higher among females and predominant among those over 64 years of age. We however found prevalence values lower than the data from a prior populational study for the same region, indicating a possible underdiagnosing of this disease.

[Evolution in consumption of anti-depressants during the years 2002 to 2004]. / Evolución en el consumo de antidepresivos durante los años 2002 a 2004.

OBJECTIVE: To analyse the use of antidepressants from 2002 to 2004 and the length of treatment. DESIGN: Cross-sectional, descriptive study of antidepressant drugs prescribed through the National Health System during 2002-2004. SETTING: Lleida Health Region, Spain. PARTICIPANTS: A total of 54,890 patients received an antidepressant drug between 2002 and 2004. MEASUREMENTS: Age, sex, medicine, prescription period, centre. RESULTS: The prevalence of antidepressant treatment was: 8.4% in 2002 (368,976 inhabitants); 8.6% in 2003 (376,638 inhabitants); and 8.7% in 2004 (388,148 inhabitants). The increase in antidepressant treatment in 2004 over 2002 was 9.4%. Prevalence among men was 5.4% and women, 12.7%. The distribution according to antidepressant classes was: selective serotonin reuptake inhibitors, 73.7%; tricyclic antidepressants, 26.2%; heterocyclic antidepressants, 10%, and monoamine oxidase inhibitors, 0.1%. The duration of treatment was 1 to 3 months (43%), 4 to 12 months (22.7%), 13 to 24 months (14.4%), and over 24 months (19.9%). CONCLUSIONS: A steady increase in the use of antidepressants is being observed, predominantly new drugs. Regarding the length of treatment, a high proportion of patients are treated for under 4 months, which does not follow recent recommendations in the scientific literature for treatment of depression. This is a major element of inefficiency in the health system.
