[Effect of parental longevity and smoking on the pulmonary function in elderly persons]. / Znaczenie dlugowiecznosci rodziców oraz wplyw palenia tytoniu na czynnosc pluc w wieku podeszlym.

The significance of smoking habits and long age of parents on lung function in a large population of elderly people (559 males and 1073 females) living in the city of Cracow were analyzed. The lung function parameters correlated negatively with age of analyzed subjects (males and females). Mean values of FVC in men from long living families were 400 ml higher in comparison with other subjects, while the mean FEV1 was 330 ml higher. Such differences were not seen in females. Smoking also affected negatively lung function in the analyzed subjects. Chronic cough and sputum production did not hamper lung function, if such variables as age, height and smoking habits were not included in the analysis.

[Predictive value of ventilatory indices in elderly subjects]. / Wartosci nalezne wskazników wentylacji pluc u osób w wieku starszym.

Epidemiological studies of Kraków citizens enabled to calculate spirometric predictive values of elderly subjects. The study group was composed of 341 males and 843 females, aged 65-89 years. In every subject anthropomorphic and spirometric (FVC, FEV1.0, FEV0.5) calculations were carried out. Using the multiple regression analysis predictive indices of normal spirometric values were calculated. Monograms were also made, allowing easy access to normal values.
