RESUMEN
OBJECTIVE: Hypothyroidism is the most common condition linked to a hormone deficiency, nevertheless data on its prevalence are scarce in Spain. For that reason, we have estimated its prevalence through the registration of patients who had used thyroid hormones in Andalusia (South Spain). METHODS: Data of patients who had withdrawn levothyroxine under the public system during 2014 from the base of the Andalusian Health Service were considered. Prevalence were calculated with confidence intervals of 95% for each management area, stratified by sex and age groups, and differences between them were evaluated. RESULTS: 321,368 people (98% older than 18 years and 83% female) were identified as levothyroxine users and a prevalence of hypothyroidism of 3.95% (95%CI:3.94-3.96) was estimated for the general population. The condition was more common in females, in the older 18 years 7.81% (95%CI:7.80 to 7.82) compared to males 1.75% (95%CI:1.73-1.77) with a ratio of 4.5-fold. It increases in the population of women older than 45 years, 10.32% (95%CI:10.30-0.32) and in the over 60 years 11.37% (95%CI: 11.35-11.40). The prevalence in adult women in the western provinces is 7.38% (95%CI:7.36-7.40), in the eastern provinces 8.59% (95%CI:8.57-8.62) and in coastal areas 6.70% (95%CI: 6.68-6.72) compared to the mountainous ones, which is 8.91% (95%CI:8.88-8.94). CONCLUSIONS: The results denote a high prevalence of hypothyroidism in the adult population of Andalusia compared to the nearby countries, with a clear increased associated with females and age. Furthermore, the prevalence of the illness presents also a geographically-related variability.

BACKGROUND: Hypothyroidism (HT) is a common condition in clinical practice. There is a paucity of recent data on its prevalence in Spain, suggesting the need for an updated estimate and therefore the aim of this study was to determine its prevalence in the province of Cádiz. METHODS: We obtained data relative to medical prescriptions for group H03AA drugs issued in primary care centers attached to the Andalusian Health Service in the province of Cadiz in 2012. Prevalence was estimated on the basis of the defined daily dose (DDD), the prescribed daily dose (DDP) and treated patient records (TPR). We present the estimated prevalence and odds ratio by gender, with a confidence interval of 95%. RESULTS: Prevalence of HT in 2012 in the population aged 15 years and over in the province of Cadiz was 1.36% (CI95: 1.33%-1.38%) based on DDD; 2.60% (CI95: 2.54%-2.66%) based on DDP; and 3.10% (CI95: 2.85%-2.93%) based on TPR. Median age was 56 years (IQR: 43 to 68). Prevalence (TPR) by gender was 0.75% in men and 5.36% in women [OR 7.26 (CI95: 7.02-7.52)]. The greatest prevalence, 9.35%, was found in the group of women aged 51 to 70 years. CONCLUSIONS: Prevalence of HT in Cadiz is high, mainly affects women. Current prescribing systems allowed us to obtain TPRs, which have been shown to be a more valuable tool than DDDs for estimating HT prevalence.

Fundamento: El hipotiroidismo es la condición más común ligada a un déficit hormonal. A pesar de ello existe una escasez de datos en España sobre su su prevalencia. El objetivo fue estimar la prevalencia en Andalucía a través del registro de pacientes que consumieron hormona tiroidea durante el año 2014. Método: Se recuperaron los datos de las personas que habían retirado de la farmacia levotiroxina con cargo al sistema público durante 2014 de la base de datos del Servicio Andaluz de Salud. Se calcularon las prevalencias con sus intervalos de confianza del 95% para cada Área de Gestión, estratificadas por sexo y grupos etarios. Resultados: Se identificaron 321.368 personas (98% mayores de 18 años y 83% mujeres) consumidoras de levotiroxina y se estimó una prevalencia de hipotiroidismo del 3,95% (IC95%: 3,943,96) para población general. La condición era más común en la mujer, en mayores de 18 años un 7,81% (IC95 7,80 a 7,82) comparada con el hombre 1,75% (IC95 1,73 a 1,77) con una razón de 4,5. Aumenta en la población de mujeres mayores de 45 años, 10,32% (IC95 10,30 a 10,32) y más en las mayores de 60 años 11,37% (IC95%: 11,35 a 11,40). La prevalencia en mujer adulta de las provincias occidentales fue 7,38% (IC95%: 7,36-7,40), en las orientales de 8,59% (IC95%: 8,57-8,62) y en las áreas costeras fue de 6,70% (IC95%: 6,68-6,72) frente a las montañosas que fue 8,91% (IC95%: 8,88-8,94). Conclusión: Los resultados indican una elevada prevalencia de hipotiroidismo en la población adulta de Andalucía, con un claro predominio de la mujer y un incremento con la edad. Además, la prevalencia de la enfermedad también presenta una importante variabilidad geográfica (AU)

Fundamentos: El hipotiroidismo (HT) es una patología frecuente en la práctica clínica diaria. No existen datos recientes sobre su prevalencia en España. El objetivo de este trabajo fue conocer su prevalencia en la provincia de Cádiz. Métodos: Se estudió el consumo del grupo terapéutico H03AA realizado en receta oficial por las unidades de Atención Primaria (AP) de Cádiz, durante el año 2012. La prevalencia se estimó mediante tres métodos: la Dosis Diaria Definida (DDD), la Dosis Diaria Prescrita (DDP) y el Registro Pacientes en Tratamiento (RPT). Los resultados se presentaron según sexo y edad con intervalos de confianza del 95%. Resultados: La prevalencia de HT durante 2012 en población mayor de 15 años de la provincia fue del 1,36% (IC95: 1,33%-1,38%) mediante DDD, del 2,60% (IC95: 2,54%-2,66%) mediante DDP y del 3,10% (IC95: 2,85%-2,93%) mediante RPT. La mediana de edad fue de 56 años (rango intercuartílico 43 a 68 años). La prevalencia (RPT) por sexo fue de 0,75% en hombres y 5,36% en mujeres [OR 7,26 (IC95: 7,02-7,52)], siendo del 9,35% la correspondiente a mujeres de 51 a 70 años. Conclusiones: El método de estimación por RPT demuestra ser una herramienta más válida que el método DDD para evaluar la prevalencia de HT. El HT muestra, en nuestra provincia una prevalencia elevada con mayor afectación del sexo femenino (AU)
