16. Biosocial factors in the epidemiology of childhood asthma in a British national sample.
The relation between biosocial factors and childhood asthma in a British national sample (n = greater than 14 000) is examined. The presence of asthma was found to associate with sex of the child, parental age and occupation, housing type, and overcrowding as well as eczema and some infectious diseases. Discriminant analysis showed that it was possible to di

17. Respiratory symptoms questionnaire for asthma epidemiology: validity and reproducibility.
BACKGROUND: There is a need for a new respiratory symptoms questionnaire for use in epidemiological research in asthma. METHOD: A questionnaire was designed following a pilot study in 78 subjects. It contains nine questions on symptoms such as wheeze and difficulty with breathing in defined circumstances such as exercise and sleep. It was completed by 211 ad

18. A generic model for the assessment of disease epidemiology: the computational basis of DisMod II
Epidemiology as an empirical science has developed sophisticated methods to measure the causes and patterns of disease in populations. Nevertheless, for many diseases in many countries only partial data are available. When the partial data are insufficient, but data collection is not an option, it is possible to supplement the data by exploiting the causal r

19. Asthma, allergy, and atopy in three south-east Asian populations.
BACKGROUND--Whilst many recent reports have suggested a rise in the prevalence of asthma and allergic disease in Western countries, little is known about the epidemiology of these common conditions in south-east Asia. This study compared the prevalence of asthma and allergic disease amongst secondary school students in three south-east Asian populations--Hon

20. Identifying and managing adverse environmental health effects: 4. Pesticides
PESTICIDE EXPOSURE CAN CAUSE MANY DIFFERENT HEALTH EFFECTS, from acute problems such as dermatitis and asthma exacerbation to chronic problems such as chronic obstructive pulmonary disease and cancer. The resulting clinical presentations are undifferentiated, and specific knowledge of the links to environmental exposures is often required for effective diagn

21. A first trial of retrospective collaboration for positional cloning in complex inheritance: Assay of the cytokine region on chromosome 5 by the Consortium on Asthma Genetics (COAG)
The central problem of complex inheritance is to map oligogenes for disease susceptibility, integrating linkage and association over samples that differ in several ways. Combination of evidence over multiple samples with 1,037 families supports loci contributing to asthma susceptibility in the cytokine region on 5q [maximum logarithm of odds (lod) = 2.6

22. Descriptive epidemiology of bronchial reactivity in an adult population: results from a community study.
The bronchial response to inhaled histamine has been suggested as an epidemiological tool for assessing the prevalence of asthma, though the exact relationship between reactivity and asthma is unknown. Tests of bronchial reactivity to histamine were carried out in 511 subjects aged 18-64 years, randomly selected from the population in two areas of the South

23. Increase in hospital admissions for childhood asthma: trends in referral, severity, and readmissions from 1970 to 1985 in a health region of the United Kingdom.
Admissions to hospital for childhood asthma have continued to increase, but the reasons are unknown. Because the incidence of acute asthmatic attacks in the community greatly exceeds the admission rate, this increase could be a result of changes in medical practice shifting the balance of care towards the hospital without there being any underlying change in

24. Epidemiology of health and safety risks in agriculture and related industries. Practical applications for rural physicians.
Epidemiologic studies document that work in the agricultural sector is associated with many occupational health hazards. Exposure to organic dusts and airborne microorganisms and their toxins may lead to respiratory disorders. The burden of exposure-related chronic bronchitis, asthma, hypersensitivity pneumonitis, organic-dust toxic syndrome, and chronic air
