The SENIOR Project—Study of Exercise and Nutrition in Older Rhode Islanders—is a National Institute on Aging-funded, 12-month multibehavioral health promotion intervention for community-dwelling older adults (n = 1277; mean age 75.7) to increase both exercise and fruit/vegetable consumption. This study is a 2x2 experimental design with the following groups: exercise only, nutrition only, exercise plus nutrition, and control group. Intervention components (based on the Transtheoretical Model of Health Behavior Change) are stage-tailored for each individual and include manuals, newsletters, expert system assessments/reports, and telephone coaching. Outcome data are collected at times 0, 12, and 24 months. Analyses of baseline and 12-month data only are presented (24-month data are not yet available). Baseline data were analyzed to examine the relationships among the stage of change for exercise and fruit/vegetable consumption with regard to participant stages of readiness to change and the characteristics of participants at different levels of readiness to change their exercise and/or nutritional behaviors. Pearson’s chi square analysis determined that the two stage of change measures were significantly associated (c2 (1) = 5.811, p = .016)—i.e., individuals in action/maintenance for one behavior were more likely to also be in action/maintenance for the other behavior—but the association was small (h2 = .067). At 12 months a total of 950 participants provided data. Results indicated that although the exercise intervention did increase physical activity, it may also have decreased fruit/vegetable consumption. Results will be interpreted within a multiple-behavior intervention framework focusing on overburdening, enhancement, and additivity hypotheses.
