“…The factors involved with the onset and perpetuation of asthma are not well understood but most authorities regard allergic, infective and psychological factors as important (Williams cr «/.. 1958: Ford, 1969. On the basis of the skin test results of the Lufa Primary School.…”

Summary Asthma in the New Guinea Highlands is of interest because of its reported rarity. In the Eastern Highlands, seventy‐one cases of asthma were investigated over a 12 month period. In addition, a whole village community of 2000 people was examined for wheezing illness. In children and adolescents asthma was extremely uncommon with no case being identified in the community study and the youngest hospital case being 10 years old. The prevalence of active asthma in adults was estimated to be 0.2–0.3%. Compared with European countries, the age at onset was much later with 58% starling after the age of 30 years. The sex ratio was almost equal. Cutaneous sensitivity to allergens was assessed using the prick lest. In asthmatics, reactions to D. pteronyssinus were positive in all cases. Multiple sensitivities were common and did not diminish with increasing age at onset. In 335 unselected controls of all ages, 19% were positive to allergens, 14% of them to D. pteronyssinus. D. pteronyssinus was identified in ail house dust samples from both village and urban dwellings. Asthma occurred in both traditional and European‐influenced environments, but the importance of social change remains uncertain.

“…It has therefore been suggested that they are better regarded as forming part of a single diagnostic entity, chronic obstructive lung disease (Ciba Guest Symposium, 1959;Mitchell and Filley, 1964;Burrows et al, 1965). This concept has been criticized as implying 'diagnostic defeatism' (Scadding, 1971), in that asthnma and chronic bronchitis can usually be distinguished fairly easily and probably involve different pathological processes (Ford, 1969). A survey of asthmatic characteristics in the community was therefore undertaken in order to clarify the clinical picture of these diseases.…”

. (1975). Thorax, 30,[663][664][665][666][667][668]. A community survey of asthmatic characteristics. A survey was undertaken among adults aged 20-44 years in a South Wales town. Persons with a history of wheezing with breathlessness and in the absence of a cold were identified by postal questionnaires and seen at a clinic, together with a sample of subjects without these symptoms. The response rates for the first and second stages of the survey were 99 6 % and 91 0 % respectively, and 574 subjects were ultimately seen.Asthmatic patients (those receiving treatment within the previous year) had some airways obstruction at rest, which increased after exercise. They also had strong allergic tendencies, as shown by personal and family history, skin tests, and serum IgE levels. The ex-asthmatics (those not receiving treatment within the previous year) showed these tendencies to a lesser extent. A larger group gave a history of wheezing but stated that they had never had asthma; in their response to exercise and allergic traits they resembled the control group rather than the asthmatics, and appeared to have the features of chronic bronchitis. Asthma and chronic bronchitis would therefore seem to be distinct clinical entities within the population studied.

“…If by aetiology, asthma can be classified as either extrinsic or intrinsic (Ogilvie, 1962;Ford, 1969), children with both asthma and eczema may be similar to those with an 'allergic tendency' who suffer the more extrinsic form of the disease.…”

. Asthma in schoolchildren. The frequency of asthma in 10 971 schoolchildren between the ages of 5 and 14 years was reported by their parents to be 3 8%. Of these, 20'7% were said to have had bronchitis, 5 9% pneumonia, and 4 7% eczema. Asthma was reported more commonly in boys than girls and was greatest in children of social classes I and II. One-third of the children were reported to have had their first attack before the age of 2 years. Few (18 %) first attacks started after the age of 5 years. There was no evidence that bronchitis predisposed to the later development of asthma, or vice versa. Within each age-sex group children with a history of asthma had lower peak expiratory flow rates than children who gave no such history. These differences in PEFR were greater than for children with a history of bronchitis.The likelihood that chronic bronchitis has its origins in childhood has been emphasized by several population studies (Lunn, Knowelden, and
