Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Systolic Blood Pressure | Blood pressure at 12 months will be the primary outcome. Blood pressure will also be measured at baseline and at the 3-month mark to track blood pressure during the entire participation period. | 12 months | |
Secondary | Dyslipidemia | non-HDL cholesterol will be measured at 12-months. The same measurements will be taken at baseline and at the 3 month mark in order to track measurements throughout the entire participation period. | 12 months | |
Secondary | Percentage of Glycated Hemoglobin (Hemoglobin A1C) | Hemoglobin A1C will be measured at 12-months. The same measurements will be taken at baseline and at the 3 month mark in order to track measurements throughout the entire participation period. | 12 months | |
Secondary | Inflammation: C-reactive Protein | C-reactive protein will be measured at 12-months. The same measurements will be taken at baseline and at the 3 month mark in order to track measurements throughout the entire participation period. | 12 months | |
Secondary | Body Mass Index | Body mass index will be measured at 12-months with a height and weight ratio. The same measurements will be taken at baseline and at the 3 month mark in order to track measurements throughout the entire participation period. | 12 months | |
Secondary | Waist Circumference | Waist circumference will be measured at 12-months according to the National Institutes of Health (NIH) guidelines. The same measurements will be taken at baseline and at the 3 month mark in order to track measurements throughout the entire participation period. | 12 months | |
Secondary | Physical Activity | The International Physical Activity Questionnaire (IPAQ) Short 7-Day version will be collected as part of the 12 month outcome survey. The questionnaire will also be collected at baseline and 3 months to track changes over the entire study period. The IPAQ score reflects energy expenditure of physical activity, and is reported in units of 'met minutes' which means metabolic equivalent. The minimum value is zero and there is no maximum. Higher scores mean better levels of physical activity. | 12 months | |
Secondary | Salt Intake | A single question, "Are you currently watching or reducing your sodium or salt intake?" from the Behavioral Risk Factor Surveillance System 2013, which has a dichotomous 'yes/no' response, will be collected as part of the 12 month outcome survey. The question will also be collected at baseline, 3 months, and at 8 months, to track changes over the entire study period | 12 months | |
Secondary | Soda Intake | A single question from the California Health Interview Survey (CHIS) 2011-2012 will be collected as part of the 12-month outcome survey. The question is "During the past month, how often did you drink regular soda or pop that contains sugar?" The participant gives a number, and the frequency (per day, per week, or per month) is also recorded. The average daily servings of soda over the prior month is calculated, and the question is scored as a dichotomous variable of greater than or equal to 1 serving of soda per /day versus less than one serving of soda per day. The question will also be collected at baseline and at 3 months, to track changes over the entire study period | 12 months | |
Secondary | Fruit and Vegetable Intake | Two questions from the California Health Interview Survey (CHIS) 2011-2012 will be collected as part of the 12-month outcome survey. The questions are "During the past month, how many times did you eat fruit? Do not count juices" and "During the past month, how many times did you eat any other vegetables like green salad, green beans or potatoes? Do not include fried potatoes." For each question, the participant gives a number, and the frequency (per day, per week, or per month) is also recorded. Responses are converted to a number for day for each question, then summed across the two questions. The question is scored as a dichotomous variable of five or more servings of fruit and vegetables per day versus less than five servings of fruit and vegetables per day. The questions will also be collected at baseline and at 3 months, to track changes over the entire study period | 12 months | |
Secondary | Smoking | A single question from the California Health Interview Survey 2011-2012 Adult Questionnaire will be collected as part of the 12-month outcome survey. The question asks whether over the interval since the previous study interview, "were you smoking cigarettes every day, some days, or not at all?" The question will also be collected at baseline (with a time frame of over the prior year) and at 3 months, to track changes over the entire study period. The scoring for this outcome is dichotomous: "Smoking" = a response of 'every day' or 'some days', versus "Not smoking" = a response of 'not at all.' | 12 months | |
Secondary | Knowledge About Stroke Signs | An open-ended question about what the participant believes is a sign of a stroke ("What are the warning signs of a stroke? What else...what else?"), will be asked as a part of the 12 month survey. This question will also be collected at 3 months to track changes over the follow-up study period. Correct responses are numbness, weakness, difficulty speaking/understanding, vision disturbance, dizziness, and headache. Responses are scored as 0 correct, 1 correct, 2 correct, and 3 or more correct. | 12 months | |
Secondary | Knowledge About Stroke Risk Factors | An adaptation of an existing instrument will be collected as a part of the 12 month survey. An open-ended question about what the participant believes is a stroke risk factor ("I would like to ask you about stroke risk factors, those are the things that make it more likely for somebody to have a stroke. From anything you might have heard or read, what do you believe are the risk factors associated with stroke? What else...what else?", will be asked, then converted to three dichotomous variables: correct about at least 3 stroke risk factors versus less than three; correct about at least one stroke risk factor versus none correct; and reports that blood pressure is a stroke risk factor versus does not. This question will also be collected at baseline, 3 months, and 8 months to track changes over the entire study period. | 12 months | |
Secondary | Patient Perception of Quality of Stroke Preventative Care | An adaptation of the Consumer Assessment of Healthcare Providers and Systems (CAHPS) will be collected as a part of the 12 month questionnaire. It will also be collected at baseline and 3 month to track changes over the entire study period. The CAHPS question was "Did you receive from any of your medical care providers the help you needed to make changes in your habits or lifestyle that would improve your health or prevent illness?" Response choices are: 'Yes definitely' "Yes somewhat' or 'No definitely not'. | 12 months | |
Secondary | Vascular Events | The Questionnaire for Verifying Stroke Free Status (QVSFS) will be collected as part of the 12 month survey. It will also be collected at baseline and 3 months to track changes over the entire study period. This questionnaire will also be collected every 6 months for up to 24 months after the study is completed to check for vascular events. The scoring was dichotomous: at least one new event (stroke, transient ischemic attack, or heart attack) versus none over the 12-month follow-up period. | 12 months | |
Secondary | Medication Adherence - Global | A single item adapted from two questions published elsewhere will be administered at 12 months. The adapted item is "In the past week, how much of the time were you able to take your medications exactly as your doctor or nurse told you to?" Response choices are 'None of the time,' 'A little of the time,' "A good bit of the time,' 'Most of the time,' or 'All of the time.' This item will also be collected at Baseline, 3 Months, and 8 Months, to track changes over the entire study period. | 12 Months | |
Secondary | Medication Adherence - Blood Pressure Medication | A continuous measure of adherence as percentage of doses taken over the prior 7-day time period will be collected at 12 months and calculated for blood pressure medication, using a previously published formula. This will also be collected at 3 months, to track changes over the study period. | 12 Months | |
Secondary | Medication Adherence - Cholesterol Medication | A continuous measure of adherence as percentage of doses taken over the prior 7-day time period will be collected at 12 months and calculated for cholesterol medication, using a previously published formula. This will also be collected at 3 Months, to track changes over the study period. | 12 months | |
Secondary | Medication Adherence - Antithrombotic Medication | A continuous measure of adherence as percentage of doses taken over the prior 7-day time period will be collected at 12 months and calculated for antithrombotic medication, using a previously published formula. This will also be collected at 3 Months, to track changes over the study period. | 12 months | |
Secondary | Medication Adherence - Antidepressant Medication | A continuous measure of adherence as percentage of doses taken over the prior 7-day time period will be collected at 12 months and calculated for antidepressant medication, using a previously published formula. This will also be collected at 3 Months, to track changes over the study period. | 12 months |
