Abstract

International Journal of Exercise Science 8(3): 265-276, 2015. While there is strong evidence measuring the association between leisure time physical activity (LTPA) and socioeconomic status (SES) there are limited data on the relationship between cardiorespiratory fitness (CRF) and SES. The purpose of this cross-sectional study was to examine differences in CRF and LTPA between household income and individual education in young adults. A sample of 171 (males n=98, female n=73) young adults participated in the University of Pittsburgh-Physical Activity Study. Participants completed CRF testing. Demographic characteristics were assessed via interviewer administered standardized survey and LTPA was assessed using the interviewer administered Modifiable Activity Questionnaire. Participants were grouped by income and education level. Analysis of variance and general linear modeling was used to compare LTPA and CRF between groups. There were no differences in CRF between income levels (p=0.126) or education levels (p=0.990) for the total sample. There were no differences in LTPA between income levels (p=0.936) or education level (p=0.182) for the total sample. Results suggest that neither income nor education levels are indicators of CRF in this sample of young adults. Other environmental, sociological, or familial health mediators may have a strong effect on CRF in young adult males and females.
