Multiple Risk Factor Intervention Trial

Study Overview
=================
Brief Summary
-----------------
Ms. FIT pilot is a pilot study of a 3-arm RCT with equal recruitment and stratification of pre and postmenopausal women with risk factors for chronic disease to: 1) Canadian guidelines-based physical activity alone; 2) Canadian guidelines-based physical activity and healthy eating; or 3) stretching attention control. The purpose of this study is to evaluate the feasibility, acceptability, and preliminary efficacy of the interventions. The objectives are to: 1) pilot test the intervention delivery protocol in a real-world application (management and technical capabilities of the research group); 2) evaluate adherence and participant acceptability of a combined in-person and virtual intervention delivery in both pre and post-menopausal women; 3) identify the preliminary efficacy of the interventions on select cardiometabolic risk markers.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Physical activity intervention feasibility | Determined as an average adherence to physical activity guidelines of ≥100% measured via Garmin smartwatch | end of week 6 | 
| Diet quality intervention feasibility | Determined as a 5-point improvement in diet quality measured via healthy eating index from 3-day diet record | end of week 6 | 
| Intervention acceptability | Assessed via researcher-developed questionnaire | end of week 6 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Systemic insulin resistance | As assessed by the Matsuda Index calculated from an oral glucose tolerance test | 6 weeks | 
| Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) | calculated as: (fasting insulin*fasting glucose)/22.5 | 6 weeks | 
| Framingham 10-year risk (%) | Calculated using standardized scoring system | 6 weeks | 
| Lipid profile | analyzed from blood | 6 weeks | 
| C-Reactive Protein | analyzed from blood | 6 weeks | 
| Blood pressure | Measured after several minutes of supine rest | 6 weeks | 
| Aortic stiffness (central to femoral) | Measured via Shygmacor device | 6 weeks | 
| Brachial artery endothelial function | Measured via flow-mediated dilatation test | 6 weeks | 
| Cardiorespiratory fitness | Measured as peak volume of oxygen consumption via indirect calorimetry | 6 weeks | 
| Whole-body fat and fat free mass | Measured by BodPod | 6 weeks | 
| Body circumferences | Waist, hip and neck circumferences measured by inelastic tape | 6 weeks | 
| Depressive symptoms | measured by Beck Depression Inventory; score ranges from 0-63 with a higher score indicating more severe depression | 6 weeks | 
| Dietary intake | Assessed via ASA-24 3-day food records | 6 weeks | 
| Menopausal symptom presence and severity | assessed by The Menopause-specific Quality of Life (MENQOL) questionnaire. Each of four domains is constrained between 1 to 8 where a higher score indicates more symptoms. | 6 weeks | 
| Health-related quality of life | Assessed by RAND-36, where an independent score is provided for 8 scales ranging from 0 to 100 with a higher score indicating better quality of life | 6 weeks | 
| Psychosocial stress | assessed by the perceived stress scale where individual scores can range from 0 to 40 with higher scores indicating higher perceived stress | 6 weeks |
