Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Exercise Behavior | The Godin Scale was used to assess weekly exercise frequency and intensity | 12 months | 
| Fruit & Vegetable Consumption | Total daily servings of reported fruits and vegetables (maximum of 10) were calculated using a composite measure that summed separate responses for fruits and vegetables. | 12 months | 
| Mammography Screening Behavior | We used responses to two questions to create a dichotomous measure of whether or not female respondents (all aged 50 to 70) received a mammogram in the past year. | 12 months | 
| Colorectal cancer screening | A measure of up-to-date colorectal cancer screening status was assessed using individuals' self-reports of recency of colonoscopy (within 10 years), sigmoidoscopy (within five years), and/or fecal occult blood test (FOBT) within one year. | 12 months |
