RESUMO
The purpose of the study was to evaluate the influence of body size and shape, and of fat distribution on respiratory functions in adult women. The sample consisted of 107 women aged 17-82 years. Height, weight, chest, waist and hip circumferences, abdominal, and subscapular and triceps skinfolds were examined. The BMI and WHR were calculated. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), peak expiratory flow (PEF), maximal expiratory flow (MEF75), forced expiratory time (FET) were used as measures of respiratory function. Positive correlations were found between z-scores of height and VC, FEV1, FVC, between WHR and VC, and between circumference and FET. Negative correlations were found between z-scores of BMI and VC, FEV1, between subscapular skinfold and VC, FEV1, FVC and between abdominal skinfold and VC. Stepwise multiple regression analysis showed that traits of body size and shape mostly influenced VC (32 %) and FVC (31 %). Body height and WHR significantly affected VC, while height and subscapular skinfold affected FVC. A significant association between fat distribution described by BMI, WHR, and skinfold thickness and respiratory parameters was observed. These results confirm a complex effect of body size and shape, and of fat distribution on respiratory function.

The study was carried out on 290 males with occupational organic dust exposition. In all bronchoprovocation test with Erwinia herbicola antigen were carried out. A positive test was seen in 16.2% of the studied subjects. Bronchial hyperreactivity to Erwinia herbicola allergen depended on living environs, occupational exposure and symptoms characteristic of allergic alveolitis.

A group of 153 patients with bronchial asthma were subjected to bronchial provocation and intracutaneous tests with allergen from the gram negative bacterium Erwinia herbicola which commonly occurs in organic dusts. Of this group, 80 persons were also examined with both tests with the allergen of Aspergillus fumigatus and 96 persons with the house dust extract. The frequency of positive skin reactions to the tested allergens was much greater than that of the positive bronchial reactions. No significant correlation was found to exist between the frequency and intensity of the bronchial and skin reactions except for delayed and late reactions to Erwinia herbicola. The authors conclude that bronchial provocation tests represent a much more specific and reliable method in the assessment of the clinical status of patients with extrinsic asthma than do skin tests.
