BACKGROUND: Contact with family physicians by older adults may be linked to their physical fitness in addition to other health, behavioral, and sociodemographic determinants. We studied a stratified random sample of urban community-dwelling elderly patients in London, Ontario, Canada, to describe the interaction of physical fitness measures and a number of health and lifestyle behaviors and sociodemographic outcomes with family physician contact over 1 year. We hypothesized that physician contact would be associated with lower indices of physical fitness and that association would be similar to other known determinants of physician utilization. METHODS: Three hundred seventy-five noninstitutionalized elderly men (N = 185) and women (N = 190) ages 55 to 84 years were recruited from the municipal tax assessment list for the city of London (population 280,000). Four categories of independent variables were selected to reflect common determinants of health (physical fitness, self-reported and clinically measured health, lifestyle behaviors, and sociodemographics). The association between these categories of variables and self-reported contact with family physicians and a variety of health professionals was determined for the year prior to the study. RESULTS: Forty-six percent of the subjects had at least one physician contact in the month prior to the study and 79% within the previous year. None of the other health professions (including nursing, chiropractic, physiotherapy, homemaking, and dentistry) were contacted more than once in the previous year. Lifestyle and sociodemographic variables including activity habits, smoking, income, marital status, and education were not associated with physician contact, whereas poor self-reported cardiovascular health and use of cardiovascular and pulmonary medications were associated with physician contact. Interestingly, physical fitness variables including maximal aerobic capacity, grip strength, and hip flexibility were not associated with physician contact. CONCLUSIONS: The absence of an association among physical fitness, lifestyle, and sociodemographic variables and physician contact was not anticipated and may be due to the selection of individuals who were independent, active community dwellers. It may be that most of the physician contact in this relatively healthy and physically fit sample was preventive in nature, for example, monitoring common chronic disease states in the elderly including cardiovascular and pulmonary disease. This paper reports baseline data from a longitudinal study of the interaction between physical fitness and health outcomes in groups of older community-dwelling individuals. As this group ages further, it would be interesting to determine the use of the health care system in relation to their changing functional and health status. In particular, do chronic health conditions such as cardiovascular disease, which increase in prevalence with age, become modified through maintenance of physical fitness and does this impact on health service use?
