Iodine status and thyroid function among Spanish schoolchildren aged 6-7 years: the Tirokid study.

I deficiency is still a worldwide public health problem, with children being especially vulnerable. No nationwide study had been conducted to assess the I status of Spanish children, and thus an observational, multicentre and cross-sectional study was conducted in Spain to assess the I status and thyroid function in schoolchildren aged 6-7 years. The median urinary I (UI) and thyroid-stimulating hormone (TSH) levels in whole blood were used to assess the I status and thyroid function, respectively. A FFQ was used to determine the consumption of I-rich foods. A total of 1981 schoolchildren (52 % male) were included. The median UI was 173 µg/l, and 17·9 % of children showed UI<100 µg/l. The median UI was higher in males (180·8 v. 153·6 µg/l; P<0·001). Iodised salt (IS) intake at home was 69·8 %. IS consumption and intakes of ≥2 glasses of milk or 1 cup of yogurt/d were associated with significantly higher median UI. Median TSH was 0·90 mU/l and was higher in females (0·98 v. 0·83; P<0·001). In total, 0·5 % of children had known hypothyroidism (derived from the questionnaire) and 7·6 % had TSH levels above reference values. Median TSH was higher in schoolchildren with family history of hypothyroidism. I intake was adequate in Spanish schoolchildren. However, no correlation was found between TSH and median UI in any geographical area. The prevalence of TSH above reference values was high and its association with thyroid autoimmunity should be determined. Further assessment of thyroid autoimmunity in Spanish schoolchildren is desirable.

Prevalence of obesity in 4-18-year-old population in the Basque Country, Spain.

The objective of the study was to estimate the prevalence of overweight and obesity in children and adolescents in the Basque Country, Spain. It consisted of an analysis of baseline data of the Nutrition Survey, a cross-sectional study, carried out in 2004-2005. The study population comprised child and adolescent living in the Basque Country. The analysis was carried out in a representative random sample of 1178 people aged 4-18 years. Anthropometric examinations were undertaken by trained observers using standardized methods and included measurements of weight and height. Subjects were classified into different body mass index categories, according to the International Obesity Task Force guidelines. A 5.4% of the population studied was obese; 6% of males and 4.7% of females, the highest in the 11-14 age group in boys (7.2%) and in the 4-6 age group in girls (12.5%). Overweight (22.9%) was slightly higher in girls. The highest prevalence of excess weight (overweight+obesity) was observed in girls aged 4-6 years (38.4%), decreasing with age. Subjects in the 15-18 age group rated 16.6%. Boys evidenced a higher excess weight rate in the 11-14 (32.9%) and 7-10 (32%) age groups; the lowest rate was found in the 4-6 age group. Prevalence of obesity was higher in the less privileged socio-economic strata (6.9% vs. 5.2%), for both boys and girls. However, this trend was observed only in girls for overweight (25.9% vs. 21.8%). This study shows a high prevalence of obesity and overweight in the studied population and similar to other European countries and regions.

Guía de Práctica Clínica para el Manejo del Sobrepeso y la Obesidad en Personas Adultas / Clinical Practice Guideline for the Management of Overweight and Obesity in Adults

La obesidad es una enfermedad crónica multifactorial de gran trascendencia sociosanitaria y económica y constituye un problema de salud pública. Causa o empeora un gran número de problemas relacionados con la salud: diabetes, enfermedad coronaria, hipertensión y determinados tumores. Se asocia con mayor riesgo de mortalidad cardiovascular, mayor prevalencia de alteraciones psicopatológicas, incremento del coste sanitario y disminución de la esperanza de vida. Actualmente en España, la prevalencia de exceso de peso afecta aproximadamente al 50% de la población. La Sociedad Española de Endocrinología y Nutrición (SEEN) ha elaborado una Guía de Práctica Clínica sobre el diagnóstico, la evaluación y el tratamiento del sobrepeso y de la obesidad en adultos estructurada en dos partes: 1) Definición y clasificación, epidemiología, etiopatogenia, complicaciones, beneficios de la reducción ponderal y evaluación del enfermo con sobrepeso u obesidad; 2) identificación de enfermos con riesgo de obesidad subsidiarios de tratamiento, objetivos de tratamiento y estrategias terapéuticas disponibles para conseguirlos, indicándose además, el grado de recomendación basado en la evidencia científica sobre cada uno de estos aspectos. Aun siendo la obesidad una enfermedad que debiera implicar no sólo a personal sanitario, sino también a autoridades políticas, agentes sociales, educadores e industria alimentaria entre otros, la SEEN ha querido desarrollar esta guía dados los evidentes aspectos endocrinológicos y metabólicos de este trastorno. Esta guía establece recomendaciones basadas en la evidencia científica para ayudar a tomar decisiones sobre el diagnóstico, la evaluación y el tratamiento del exceso ponderal en adultos y posibilitar una atención más homogénea y de calidad (AU)

Obesity is a chronic, multifactor disease with sizeable socio sanitary and economic consequences and is an issue in public health, mostly in developing countries. It causes or exacerbates a large number of health problems: diabetes, coronary heart disease, hypertension, and the incidence of certain cancers. It has been linked to a greater risk of cardiovascular mortality, a higher prevalence of psychopathology disorders and social maladjustment with a higher health care cost and shorter life-expectancy. In Spain, nowadays, the prevalence of overweight and obesity is nearly 50% of population. SEEN has developed a Clinical Practice Guide on diagnosis, evaluation and treatment of overweight and obesity in adult people with two sections: 1) Definition and classification of adult obesity, its epidemiology, etiopathogeny, complications, benefits of weight reduction and clinical evaluation of patients with overweight or obesity, and 2) Identification of patients with obesity risk subsidiary to weight reduction treatment, therapy goals and therapeutical strategies available to achieve them indicating as well the degree of recommendation based upon scientific evidence on each aspect. Although obesity is a disease which is supposed to involve not only medical but also political authorities, social agents, educators and food industry among others, SEEN decided to develop this Guide taking into account the evident endocrinological and metabolical aspects of this disorder. The Guide contains scientific evidencebased recommendations intended to help doctors making decisions on diagnose, evaluations and treatment of adult overweight so that a more homogeneous attendance with settled quality can be achieved (AU)
