Prevalence of severe hypercholesterolemia observed in different hospitals in Andalusia and Ceuta. / Prevalencia de hipercolesterolemias severas observadas en los distintos hospitales de Andalucía y Ceuta.

Severe hypercholesterolaemia is a major cardiovascular risk factor. Early detection and treatment can reduce the incidence of cardiovascular disease. Given the high prevalence of hypercholesterolaemia in Andalusia, the development of a screening strategy for its detection in Primary Care may be an efficient measure. OBJECTIVE: To identify patients in Primary Care with severe hypercholesterolaemia that may increase their cardiovascular risk by reviewing LDL-cholesterol results in computerised laboratory systems. MATERIAL AND METHODS: Observational, retrospective, multi-centre study in 16 hospitals in Andalusia and Ceuta. Anonymous analytical data were acquired from the different laboratory computer systems for the year 2018, and exclusively from Macarena Hospital for the year 2019. RESULTS: From a total of 1,969,035 determinations on≥18 years old, 2,791 patients (0.14%) were detected with LDL-cholesterol>250mg/dl and from a total of 2.327.211 determinations studied in children under 18 years old, 3,804 patients (0.16%) were detected with LDL-cholesterol>135mg/dL. The highest incidence of possible genetic hypercholesterolaemia in adults corresponded to the province of Seville with 23.6 cases/1,000 determinations, while in minors, the highest incidence corresponded to the province of Cadiz with 75 possible cases/1,000 determinations. A geographical triangle of greater prevalence is observed between the provinces of Seville, Huelva and Cadiz. CONCLUSIONS: The development of a screening strategy using a computerised review of LDL-cholesterol in Primary Care detects a large number of subjects with severe hypercholesterolaemia that could benefit from an early intervention.

Prevalencia de sobrepeso y obesidad en niños y adolescentes de 2 a 16 años / Prevalence of overweight and obesity in children and adolescents aged 2-16 years

Objetivos Calcular la prevalencia de obesidad y sobrepeso en niños y adolescentes de nuestra ciudad e investigar los factores asociados. Sujetos y métodos Estudio transversal de 1.317 niños y adolescentes de 2 a 16 años. Mediante muestreo probabilístico polietápico se seleccionaron 3 grupos: 411 de 12 a 16, 504 de 6 a 12 y 402 de 2 a 6 años. Se les calculó el índice de masa corporal y se definió obesidad y sobrepeso según la International Obesity Task Force. Se realizó un cuestionario de consumo de alimentos y de características clínicas y sociodemográficas. Los resultados se expresan como porcentajes (intervalos de confianza al 95%). Mediante regresión logística múltiple se estudió la asociación entre exceso de peso (obesidad y sobrepeso) y las distintas variables, calculando la odds ratio (OR) ajustada. Resultados El 9,5% (8,0-11,0) de los niños y adolescentes de 2 a 16 años son obesos y 22,4% (23,3-24,6) tienen sobrepeso. En el grupo de 12 a 16 años, el 8,5% (5,9-11,2) son obesos y el 20,5% (16,7-24,3) tienen sobrepeso, en el grupo de 6 a 12 años el 11,6% (8,9-14,3) y el 31,0% (27,0-35,0) y en el de 2 a 6 años el 8,0% (5,4-10,6) y el 13,6% (10,3-16,9), respectivamente. Se asocian con el exceso de peso la edad (OR 1,21; p<0,001), la obesidad materna (OR 10,99; p = 0,008), el peso al nacer mayor de 4kg (OR 2,91; p = 0,002) y la lactancia artificial exclusiva (OR 1,82; p = 0,005).Conclusión La obesidad y el sobrepeso infantil y juvenil son problemas extraordinariamente prevalentes en nuestra ciudad (AU)

Objectives To estimate the prevalence of obesity and overweight in children and adolescents in our city and to investigate the associated factors. Subjects and methods A cross-sectional study of 1317 children and adolescents aged 2-16 years. Multistage probability sampling was used to select three groups of subjects: 411 aged 12 to 16 years, 504 aged 6 to 12 years, and 402 aged 2 to 6 years. Body mass index was calculated, and obesity and overweight were diagnosed using the threshold levels of the International Obesity Task Force for children and adolescents. Parents were asked about eating habits, health, social, and demographic aspects. Results are given as percentages (95% confidence interval). The relationship between obesity and overweight and the different variables was studied using multiple logistic regression. The adjusted odds ratio (OR) was calculated. Results Among children and adolescentes aged 2-16 years, 9.5% (8.0%-11.0%) were obese and 22.4% (23.3%-24.6%) were overweight. Of subjects aged 12-16 years, 8.5% (5.9%-11.2%) were obese and 20.5% (16.7%-24.3%) were overweight. In the groups aged 6-12 years and 2-6 years, rates of obesity and overweight were 11.6% (8.9% -14.3%) and 31.0% (27.0-35.0) and 8.0% (5.4%-10.6%) and 13.6% (10.3%-16.9%) respectively. Obesity or overweight was associated to age (OR 1.21; P <0.001), maternal obesity (OR 10.99; P= 0.008), a birthweight higher than 4kg (OR 2.91; p 0.002), and formula feeding (OR 1.82; P= 0.005).Conclusion Obesity and overweight in children and adolescents are highly prevalent problems in our city (AU)

Iodine intake and prevalence of thyroid autoimmunity and autoimmune thyroiditis in children and adolescents aged between 1 and 16 years.

OBJECTIVES: To determine the status of iodine nutrition in children and adolescents in Almería, Spain. To calculate prevalence of thyroid autoimmunity (TA) and autoimmune thyroiditis (AT) in pediatric ages and to research into associated factors. METHODS: Cross-sectional epidemiological study. By a multistage probability sampling 1387 children and adolescents aged between 1 and 16 were selected. Physical examination was carried out including neck palpation. Parents were asked about eating habits as well as about social and demographic aspects. Urinary iodine, free thyroxine, TSH, antiperoxidase and antithyroglobulin antibodies were measured. TA was diagnosed when any antibody was positive and AT when autoimmunity was associated with impaired thyroid function or goitre. Results are shown using percentages (and its 95% confidence interval). To study associated factors we used multiple logistic regression, quantifying the relation with odds ratio (OR), and multiple lineal regression. RESULTS: Median urinary iodine concentration was 199.5 µg/l. The prevalences of TA and AT were 3.7% (2.4-5.0) and 1.4% (0.4-2.4). TA is associated with female sex (OR 2.78; P<0.001) and age (OR 1.30; P<0.001). Iodine status is associated with the intake of milk and dairy product (P<0.001) and vegetable (P=0.021) but not with use of iodized salt at home (P=0.1). CONCLUSIONS: The iodine supply in children and adolescents in our city is optimal. Milk and dairy products are the most important iodine sources. TA and AT are prevalent in pediatric ages in our city mainly in females and older subjects.
