The focus of this study was to determine if there were patterns or trends in physical activity levels of adults in Indiana for even numbered years between 1986 - 1996. The research was a secondary analysis of data collected by the Behavioral Risk Factor Surveillance System over a ten year period for 12,682 respondents. Questions and hypotheses were examined for demographical variables of age, gender, race, marital status, income, and educational level compared to respondents being classified into one of four physical activity classifications: inactive, irregular, regular, or regular and vigorous.The data were analyzed using mean, multiple regression, and chi-square. Overall patterns and trends showed an increase since 1992 in the percentage of adults in Indiana being classified as sedentary and not meeting national guidelines for recommended levels of physical activity. There were significant differences (p=.000) between all of the demographical variables and physical activity classifications. / School of Physical Education
