Giovanni Viegi: Influence Statistics

BACKGROUND: Several studies conducted during the 1990s indicated an increase in the prevalence of symptoms of asthma; more recent investigations suggest that the trend is stabilizing or may even be reversing.

OBJECTIVE: We compared 2 cross-sectional surveys conducted in 1994 and 2002 in 8 areas in northern and central Italy, to evaluate prevalence changes for asthma, allergic rhinitis, and eczema.

METHODS: The International Study of Asthma and Allergies in Childhood methods and ...

BACKGROUND: Epidemiological studies have documented large international variations in the prevalence of asthma, and 'westernization' seems to play an important role in the development of the disease. The aims of this study were to compare the prevalence of respiratory symptoms in migrant and nonmigrant children resident in Italy, and to examine the effect of length of time living in Italy.

METHODS: Data were collected in a large cross-sectional study (SIDRIA-2) performed in 12 Italian ...

AIMS: To report on the relation between home mould and/or dampness exposure and respiratory disorders in a large sample of children and adolescents in Italy, accounting for age at time of exposure.

METHODS: 20,016 children (mean age 7 years) and 13,266 adolescents (mean age 13 years) completed questionnaires on indoor exposures and respiratory symptoms/diseases. Statistical analyses were adjusted for sex, age, questionnaire's compiler, area of residence, season of interview, parental ...

The authors studied the effects of relatively low doses of nitrogen dioxide and respirable suspended particulate matter (i.e., < 2.5 mu) on acute respiratory symptoms and on peak expiratory flow in 383 adults (15-72 yr of age) who lived in the Po River Delta area, located near Venice. During 2 wk-1 wk in winter and 1 wk in summer--the authors monitored each participant's house to measure nitrogen dioxide (in parts per billion) and respirable suspended particulate (microgram/m3) ...

OBJECTIVE: Asthma is a disease with elevated prevalence within the general population. Although general practitioners (GPs) are among the first health-care professionals to whom patients refer for their symptoms, there are few evaluations of this disease based on data provided by the GPs. The aim of this observational study is to assess the impact of asthma and comorbid allergic rhinitis on individual/social burden, quality of life, and disease control in asthmatic patients of Italian ...

BackgroundDue to the complex interplay among different urban-related exposures, a comprehensive approach is advisable to estimate the health effects. We simultaneously assessed the effect of “green”, “grey” and air pollution exposure on respiratory/allergic conditions and general symptoms in schoolchildren.MethodsThis study involved 219 schoolchildren (8–10 years) of the Municipality of Palermo, Italy. Data were collected through questionnaires self-administered by parents and children. ...

The major changes to our world are those involving the atmosphere and the climate, including global warming induced by anthropogenic factors, with impact on the biosphere and human environment. Studies on the effects of climate changes on respiratory allergy are still lacking and current knowledge is provided by epidemiological and experimental studies on the relationship between allergic respiratory diseases, asthma and environmental factors, like meteorological variables, airborne ...

Few data exist on respiratory effects of indoor air quality and comfort parameters in the elderly. In the context of the GERIE study, we investigated for the first time the relationships of these factors to respiratory morbidity among elderly people permanently living in nursing homes in seven European countries. 600 elderly people from 50 nursing homes underwent a medical examination and completed a standardised questionnaire. Air quality and comfort parameters were objectively assessed ...

Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre les MAladies Chroniques pour un VIeillissement Actif) and ARIA (Allergic Rhinitis and its ...

STUDY OBJECTIVES: To evaluate the distribution of airways obstruction in a general population sample.

METHODS: Cross-sectional epidemiologic survey of a general population sample living in Po Delta area (North Italy). Data on respiratory symptoms, diseases, and risk factors were collected through standardized interviewer-administered questionnaires. Lung function tests were performed, with criteria for defining airways obstruction based on the 1995 European Respiratory Society (ERS) ...

The effects of pet exposure on the development of respiratory symptoms have recently been the matter of vivid discussion. Our objective was to determine the effects of exposure to cat or dog in the first year of life on subsequent respiratory/allergic symptoms in children in a large Italian multicentre study. As part of the SIDRIA-2 Study (Studi Italiani sui Disturbi Respiratori dell'Infanzia e l'Ambiente 2002), the parents of 20016 children (median age 7 yr) provided information on ...

The purpose of this paper was to generate up-to-date information on the aetiology of community-acquired pneumonia (CAP) and its antibiotic management in adults across Europe. Structured searches of PubMed identified information on the aetiology of CAP and its antibiotic management in individuals aged >15 years across Europe. We summarise the data from 33 studies published between January 2005 and July 2012 that reported on the pathogens identified in patients with CAP and antibiotic ...

BACKGROUND: Community-acquired pneumonia (CAP) causes considerable morbidity and mortality in adults, particularly in the elderly.

METHODS: Structured searches of PubMed were conducted to identify up-to-date information on the incidence of CAP in adults in Europe, as well as data on lifestyle and medical risk factors for CAP.

RESULTS: The overall annual incidence of CAP in adults ranged between 1.07 to 1.2 per 1000 person-years and 1.54 to 1.7 per 1000 population and increased with age ...

Bronchial responsiveness (BR) was assessed by the methacholine challenge test in 1,694 subjects from a sample of the general population (aged 8 to 73 yr) enrolled in a prospective epidemiologic study on the natural history of chronic obstructive pulmonary disease (COPD). Information on respiratory symptoms and risk factors for COPD were obtained with a standardized questionnaire. The provocative dose causing a 10%, 15%, and 20% decrease in FEV1 was reached in 939 (55%), 658 (39%), and ...
