Introduction: with the aging process, the individual is undergoing changes, which are associated with chronic non-communicable diseases, may bring harm quality of life and functional capacity of the elderly. Understanding pulmonary changes of aging and the factors that influence pulmonary function, we can act to reduce their impact on functional capacity of the elderly. A parameter to assess lung function, which is diminished in the elderly, is a measure of the maximum pressure ventilation, which measures the strength of the ventilatory muscles, which is altered both by changes in the musculoskeletal system and in the respiratory system by aging. Objective: to determine the maximal ventilatory pressures from elderly Multidimensional Study of the Elderly in Porto Alegre (EMIPOA) – Brazil, and analyze its relationship with socio-cultural, economic, anthropometric, quality of life, activities of daily living and physical activity. Materials and Methods: this is a cross-sectional study by analysis of a database of a population-based sample of elderly EMIPOA. We evaluated 396 people, between the years 2005 and 2006, where he responded to an evaluation questionnaire with demographic information, perception of health and other information about diseases. The variables were measured by a pressure transducer for maximum ventilatory pressures, and the instruments used were International Physical Activity Questionnaire (IPAQ), Diabetes Self Care Scale (DSCS), World Health Organization Quality of Life (WHOQOL-Bref), the Barthel Index, Timed Up and Go Test (TUG test) and functional reach. Results: the values of MIP and MEP obtained for the study population were respectively 62,1± 28cmH2O and 83,8±35,9 cmH2O, men had higher values than the women (PIM = 76,9± 29,9cmH2O versus 54,5± 23,7cmH2O; p <0. 001 and PEM=111,2 ± 37,4 cmH2O against 69,7 ±25,5 cmH2O; p <0,001). Some variables had significant differences of influence in both maximum pressure ventilation, such as schooling (p=0,008), income (p<0,001), need for help in at least one usual activity (PIM p = 0,003 and PEM p = 0,036), chronic diseases, physical activity, self-perception of health, independence and quality of life. Conclusion: the study showed that the measures assesses ventilatory muscle strength change with aging and also directly from some variables such as income, level of independence, physical activity level, quality of life and functional capacity.
