Prevalencia y condicionantes de la obesidad en la población infantojuvenil de Cataluña, 2006-2012

BACKGROUND AND OBJECTIVE To estimate the prevalence of obesity and overweight in children aged 2 to 14 years in Catalonia, its trends between 2006 and 2010-2012, and to evaluate social determinants and lifestyle associated with obesity. MATERIAL AND METHODS A cross-sectional study, using the data from 4,389 surveys from Catalonia Health Surveys of the years 2006 and 2010-2012, was conducted. Obesity and overweight were determined by World Health Organization criteria. Socioeconomic position, parents education, usual diet and activity, and hours of sleep were assessed. RESULTS The prevalence of obesity and overweight were: 15.4 and 20.2% in 2010-2012. The prevalence of obesity was higher in boys (15.5%) compared to girls (12.8%) (P<.05), and higher in children ranging from 2 to 9 years old (17.5%) than children aged 10 to 14 years (7.7%) (P<.05). In 2006, the prevalence of obesity and overweight were similar to the prevalence in 2010-2012. Obesity was more frequent in children with parents with a low socioeconomic position and/or a primary or elementary parents education. CONCLUSIONS During the last 5 years (2006-2012), child obesity and overweight have remained stable in Catalonia, yet they are relatively high in Europe. Public health programmes against obesity must consider conducting an intersectional action taking social determinants and family life styles into account.

Encuestas de salud: luces y sombras

Surveys are relevant tolls to analyze social changes and its methods are appropriate to know about the distribution of perceptions and behaviors of different phenomena related to health and disease. Health surveys (HS) are usually focused on areas like social and demographic characteristics, health related behaviors, health status and health services utilization. They provide with information that is not possible to reach through other systematic data sources and are crucial to assist decision making in health policy. HS provide data from the general population which is complementary of that obtained through other procedures and takes into account the various dimensions and connections of health and health system. They are very important in health planning because of its adaptability different need, circumstances or population groups, and in all cases, when properly used, they provide with new knowledge that can be shared. Among its limitations it must be emphasized its reduced capacity to catch all the complexity of social phenomena, its high cost, and the need of a very strong work to coordinate different expert teams and its poor capacity to offer accurate estimates when little geographic areas or low prevalence phenomena are studied. The areas and opportunities for innovation in the design, data gathering and data analysis of HS are actually various and there is a need to try to optimize all its potentialities to get a better knowledge about populations’ health and social reality.

Prevalencia y carga de defectos visuales en Cataluña

The aim of this work is to determine the prevalence of visual impairment in Catalonia and analyze inequalities in vision. Cross sectional study in the population having ≥ 15 years of age (7,881 men and 8,045 women) based on data from the Encuesta de Salud de Cataluna 2006. Logistic regression models were used to calculate the adjusted odds ratio by age, civil state, level of studies, income and working situation with a confidence interval (CI) of 95%. A 4.7% (CI 95% 4.4-5.0) of the population of Catalonia, a 5.3% of female (CI 95% 4.8-5.8), and 4.1% of men (CI 95% 3.7-4.5) state that they have poor vision. The most unfavourable situations of self-reported poor vision by the Catalan population correspond to the elderly and women with lower levels of both studies and income.

Riesgo individual y poblacional en salud mental en Cataluña

Resumen Los trastornos mentales son problemas de salud con un fuerte impacto social, sanitario, economico y una importante repercusion en la calidad de vida de las personas que los padecen y de sus familias. El objetivo de este articulo es medir la prevalencia de los trastornos mentales en Cataluna y comparar los cambios observados en los resultados obtenidos entre 1994 y 2006 de la Encuesta de Salud de Cataluna a partir del Goldberg General Health Questionnaire. La poblacion con probabilidad de padecer un trastorno mental en el momento de la entrevista es similar en 1994 (12,6%) y 2006 (11,6%), con una prevalencia superior en las mujeres. Paradojicamente, entre la poblacion sin riesgo es donde se concentran los casos declarados de depresion y/o ansiedad, sentirse ansioso o deprimido, consumir antidepresivos, visitar al psiquiatra o tener un estado de salud regular o malo. Los resultados concuerdan tanto con la paradoja del riesgo como con la paradoja de la prevencion, hechos a tener en cuenta en las estrategias preventivas.Mental health disorders are health problems with a high health, social and economic impact and with relevant effects on the quality of life of both the patients and their families. The objective of this article is to measure the prevalence of mental disorders in Catalonia and to analyze changes the changes in the results obtained in the Goldberg General Health Questionnaire in the Catalan Health Survey editions developed in 1994 and 2006. The prevalence of population at risk of suffering of a mental health disorder does not differ in both years (12.6% in 1994 and 11.6% in 2006). Women showed a higher risk than men in both surveys. Paradoxically, it is amongst the people without risk where the highest number of cases of depression, anxiety, antidepressant use, psychiatry visits or bad perception of health was declared. The results agreed with the risk and prevention paradox and are relevant at the time of designing strategies for mental health disorders prevention.

Impacto de los trastornos crónicos en la esperanza de vida de la población de Cataluña en 1994 y 2006

This paper analyzes the changes in the prevalence of selected chronic conditions and their impact on the life expectancy in the population of Catalonia. The chronic conditions selected are: hypertension, diabetes, stroke, heart diseases, chronic bronchitis, asthma, chronic allergies, musculoskeletal system diseases, and anxiety/depression. The prevalence of these diseases is estimated from data collected by the Health Survey of Catalonia in 1994 and 2006. The most frequently chronic conditions among the Catalan population are the musculoskeletal disorders, the high blood pressure and the depression and/or anxiety. By the analysis of the changes in the life expectancy free of chronic disorders, this study shows the impact of these disorders in the life expectancy. The burden of the chronic morbidity in our community, and its impact on the health systems, requires further studies to increase the knowledge of this phenomenon.
