Prevalence of atherogenic dyslipidemia, related factors and level of lipid control in the general population of Galicia. GALIPEMIAS study. / Prevalencia de dislipemia aterogénica, factores relacionados y grado de control lipídico en la población general de Galicia. Estudio GALIPEMIAS.

OBJECTIVES: GALIPEMIAS is a study designed to establish the prevalence of familial dyslipidemia in the general population of Galicia. The objective of the present study was to assess the prevalence of atherogenic dyslipidemia (AD), its relationship with other cardiovascular risk (CVR) factors, and the degree of lipid control. METHODS: Cross-sectional study carried out in the general population over 18 years of age residing in Galicia and with a health card from the Galician Health Service (N=1,000). Selection of the sample by means of random sampling by conglomerates. The AD prevalence adjusted for age and sex and the related variables were analyzed. RESULTS: The prevalence of AD adjusted for age and sex was 6.6% (95% CI: 5.0-8.3%). Arterial hypertension, altered basal glycemia, type 2 diabetes mellitus and cardiovascular disease were more frequent in subjects with AD than in the rest of the population. 47.5% of the subjects with AD had a high or very high CVR. Lipid-lowering drugs were received by 38.9% (30.5% statins) of the participants with AD (46.1% of those with high and 71.4% of those with very high CVR). 25.4% of the subjects with AD had target LDL-c levels, all of them with low or moderate CVR. CONCLUSIONS: The prevalence of AD in the general adult population of Galicia is not negligible, and it was related to several CVR factors and cardiovascular disease. Despite this, this lipid alteration was underdiagnosed and undertreated.

Association of rhinitis with asthma prevalence and severity.

Asthma and rhinitis often co-exist in the same patient. Although some authors observed a higher prevalence and/or greater severity of asthma in patients with rhinitis, this view is not homogeneous and the debate continues. The aim of our study is to describe the prevalence of rhinitis in children and adolescents and to analyse their relationship with the prevalence of asthma. A multicentre study was conducted using the methodology of the International Study of Asthma and Allergies in Childhood (ISAAC). The target population of the study was all those school children aged 6-7 and 13-14 years from 6 of the main health catchment areas of Galicia (1.9 million inhabitants). The schools required were randomly selected, and all children in the targeted age ranges were included. Multiple logistic regression was used to obtain adjusted prevalence odds ratios (OR) between asthma symptoms of the schoolchildren and rhinitis prevalence. The results were adjusted for parental smoking habits, maternal education level, cat and dog exposure, and obesity. A total of 21,420 valid questionnaires were finally obtained. Rhinitis was associated with a significant increase in the prevalence of asthma in both age groups. The highest OR were 11.375 for exercise induced asthma (EIA) for children with recent rhinoconjunctivitis and 9.807 for children with recent rhinitis in 6-7 years old group. The prevalence OR's are higher in EIA and severe asthmatics. Rhinitis in children and adolescents is associated with a higher prevalence and severity of asthma.

Rationale, design and preliminary results of the GALIPEMIAS study (prevalence and lipid control of familial dyslipidemia in Galicia, northwest Spain).

AIMS: There is little information on the familial nature of dyslipidemias in the Spanish population. This knowledge could have potential diagnostic and treatment implications. The objective of the GALIPEMIAS study was to determine the prevalence of familial dyslipidemia in Galicia, as well as determine the degree of lipid control in the participants. Prevalence of atherosclerotic cardiovascular disease (ASCVD) was also estimated. This paper presents the design, methodology and selected preliminary results. METHODOLOGY: A cross-sectional study was performed in the population aged ≥18 years using cluster sampling and then random sampling. A sample of 1000 subjects was calculated and divided into three sequential phases with a specific methodology for each one. Phase I: selection of subjects from the general population and collection of informed consent documents; Phase II: collection of data from the digital clinical history to select subjects with dyslipidemia according to study criteria; Phase III: personal interview, blood analysis, family tree, and definitive diagnosis of dyslipidemia. Prevalence of different diseases and active medication was analysed. Corrected prevalence (to the reference population) of different risk factors and ASCVD was estimated. RESULTS: Phase I participation was 89.5%. We extracted complete information from 93% of the participants (Phase II). According to the study's own criteria, 56.5% (n = 527) of the participants had some form of dyslipidemia and almost 33.7% of them had familial dyslipidemia with autosomal dominant inherit pattern. The corrected prevalence of ASCVD was 5.1% (95% CI 3.1-7.2). CONCLUSIONS: Dyslipidemia was the most prevalent cardiovascular risk factor in our population with an autosomal dominant inheritance pattern in one out of every three dyslipidemia cases. Approximately, 5.1% of the sample population aged ≥18 has suffered an episode of ACVD.

Impacto do tabagismo parental sobre a asma infantil / Impact of parental smoking on childhood asthma

OBJETIVO: Avaliar a exposição da população infantil à FCA em nossa comunidade e sua relação com os sintomas de asma. MÉTODOS: Foi realizado um estudo transversal usando o questionário de estudo ISAAC em crianças e adolescentes da nossa comunidade. Pelo questionário, fez-se a definição por "já ocorreu sibilância", "asma atual", "asma grave" e "asma induzida pelo exercício". O tabagismo parental foi classificado em quatro categorias mutuamente excludentes: 1) nenhum dos pais fuma; 2) somente a mãe fuma; 3) somente o pai fuma; e 4) ambos os pais fumam. Calculou-se a odds ratio da prevalência de sintomas de asma, de acordo com a exposição à FCA, usando regressão logística. RESULTADOS: Foram incluídas, no total, 10.314 crianças e 10.453 adolescentes. Mais de 51% das crianças e adolescentes foram expostos à FCA em casa. A FCA se associa a uma prevalência mais alta de sintomas de asma, particularmente se a mãe ou ambos os pais fumam. CONCLUSÕES: A prevalência da FCA continua a ser alta em nossa comunidade, embora com uma tendência para diminuição nos últimos 15 anos. A FCA se associa a uma prevalência mais alta de asma.

OBJETIVE: To evaluate the exposure to environmental tobacco smoke (ETS) of the childhood population in this community and its relationship with asthma symptoms. METHODS: A cross-sectional study was conducted using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire on children and adolescents in this community. The symptoms "wheezing ever", "current asthma", "severe asthma", and "exercise-induced asthma" were defined by this questionnaire. Parental smoking was classified into four mutually exclusive categories: 1) no parent smokes; 2) only the mother smokes; 3) only the father smokes; and 4) both parents smoke. The odds ratio of the prevalence of asthma symptoms according to ETS exposure was calculated using logistic regression. RESULTS: A total of 10,314 children and 10,453 adolescents were included. Over 51% of the children and adolescents were exposed to ETS at home. ETS is associated with a higher prevalence of asthma symptoms, particularly if the mother or both parents smoke. CONCLUSION: The prevalence of ETS is still high in this community, although there has been a decreasing tendency in the last 15 years. ETS is associated with higher prevalence of asthma.

Exposure to paracetamol and asthma symptoms.

BACKGROUND: Paracetamol is one of the factors that have been associated with the observed increase in asthma prevalence in the last few years. The influence of environmental or genetic factors in this disease may be different in some countries than in others. The purpose of this study was to analyse the relationship between the paracetamol consumption and asthma prevalence in our community. METHODS: A cross-sectional study was conducted on more than 20,000 children and adolescents in Galicia, Spain. The International Study of Asthma and Allergies in Childhood methodology was used to collect the information on asthma symptoms in children, paracetamol consumption, body mass index (BMI), pets in the home, education level of the mother and parental asthma and smoking habits. The influence of paracetamol consumption on the prevalence of asthma symptoms was calculated using logistic regression, adjusted for the other parameters included in the study. RESULTS: After adjusting for gender, BMI, having a cat or dog, maternal education, parental asthma and smoking, in 6- to 7-year-old children, the consumption of paracetamol during the first year of life is associated with asthma [odds ratio (OR) 2.04 (1.79-2.31) for wheezing at some time]. Paracetamol consumption in the previous year leads to a significant increase in the probability of wheezing at some time [OR 3.32 (2.51-4.41)] in young children and adolescents [OR 2.12 (1.68-2.67)]. CONCLUSIONS: Paracetamol consumption is associated with a significant increase in asthma symptoms. The effect is greater the more often the drug is taken.

Objetivos: Determinar la prevalencia y variaciones geográficas de síntomas relacionados con asma enniños y adolescentes gallegos.Población y métodos: Estudio transversal según la metodología ISAAC (Internacional Study of Asthmaand Allergies in Childhood) mediante cuestionario escrito distribuido en el medio escolar. Se incluyeron10.371 niños de 6-7 años y 10.372 adolescentes de 13-14 años de todas las Áreas Sanitarias de Galicia. Seanalizaron las variaciones geográficas mediante un modelo de regresión logística.Resultados: Las sibilancias en los últimos 12 meses oscilaron en los pequeños, del 11,4 (Santiago) al 15,7%(Vigo) y en los adolescentes del 8,8 (Ourense) al 18,8% (Vigo). Según el género se observó una mayorfrecuencia en varones de 6-7 años (p < 0,001) y con tendencia a la significación estadística en las chicasde 13-14 años (p = 0,08). El riesgo (Odds ratio [OR]) de sibilancias en los últimos 12 meses, en el área demayor prevalencia con respecto a la de menor, fue 1,45 (intervalo de confianza [IC] del 95%: 1,12-1,88)en niños y 2,39 (IC 95%: 1,82-3,13) en adolescentes. La prevalencia de asma estimada para Galicia fue de13,6% en niños y 12,2% en adolescentes.Conclusiones: La prevalencia de sibilancias en los últimos 12 meses en las diferentes áreas gallegas essensiblemente superior al resto de ciudades españolas participantes en el ISAAC en los pequeños, siendomuy similar en los adolescentes, salvo en Vigo donde es sensiblemente superior. Encontramos un patróngeográficomuydefinido en los adolescentes, siendo mayores las prevalencias en la costa que en el interior(AU)

Objectives: To determine the prevalence and geographic variations of the symptoms associated withasthma in Galician children and adolescents.Population and methods: A cross-sectional epidemiological study following ISAAC (International Studyof Asthma and Allergies in Childhood) methodology, and using a written questionnaire distributed inschools. The study sample included 10,371 6-7 year-old children and 10,372 13-14 year-old adolescents,all of them from Galician Health Areas. A logistic regression model was used to analyse geographic variations. Results: In the 6-7 year-old group, wheezing in the last 12 months varied from 11.4% (Santiago) to 15.7%(Vigo) and in the adolescents varied from 8.8% (Ourense) to 18.8% (Vigo). The distribution by gender showeda predominant significance in 6-7 year-old males (P < .001), and near to be statistically significant in 13-14year-old females (P = .08). The risk (odds ratio [OR]) of wheezing in the last 12 months in the area withhighest prevalence in comparison with the area of lowest prevalence was 1.45 (95% Confidence Interval[CI], 1.12-1.88) for children and 2.39 (95% CI, 1.82-3.13) for adolescents. The estimated prevalence of asthmain the Autonomous Community of Galicia was 13.6% in younger children and 12.2% in adolescents.Conclusions: The prevalence of wheezing in the last 12 months in the different areas of Galicia is considerablyhigher than the rest of Spanish ISAAC cities in the 6-7 years group and very similar in the 13-14 yearsgroup, except in Vigo where it is considerably higher. We found a clearly defined geographic pattern inthe adolescent group, with higher prevalences in coastal areas than in the interior(AU)
