Brief summary
This research program aims to investigate the clinical, physiological, metabolic and molecular effects of lifestyle change in patients with systemic lupus erythematosus with high cardiovascular risk. This 6-month parallel-group randomized controlled trial aims to investigate the feasibility and efficacy of a newly developed lifestyle change intervention - through recommendations for structured and unstructured physical activity and healthy eating - on increasing physical activity level and improving eating habits. Potential effects of the intervention on cardiovascular and cardiometabolic risk factors, health-related quality of life, symptoms of anxiety and depression, sleep quality and immune function will be investigated. Gold-standard techniques and a variety of analyses will be performed to access the potential mechanisms involved in response to this intervention.
Interventions
BEHAVIORALLiving well with Lupus
The lifestyle change intervention will involve two constructs: increasing the level of physical activity and improving eating habits, each with its own specific domains and goals. It will be based on a structured program of physical exercises and selection of individualized goals in the domains of transportation, leisure and work to reduce sedentary behavior with the aim of increasing the level of physical activity, as well as establishing changes in dietary aspects, involving consumption domains, structure, behavior and eating attitude using nutritional counseling techniques.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Risk cardiovascular score | 6 months | assessed by measures of five standard variables (HDL cholesterol, triglycerides, fasting blood glucose, waist circumference and blood pressure - average of systolic and diastolic blood pressures). Z-score = \[(50 - HDL cholesterol)/sd + (triglycerides - 150)/ sd\] + \[(fasting blood glucose - 100)/ sd\] + \[(waist circumference - 88)/ sd\] + \[(blood pressure - 115)/ sd\]. Higher score values represent higher risk. \*sd: standard deviation. Higher Z-score represent higher risk. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Waist circumference (cm) | 6 months | assessed by measuring tape positioned at the midpoint between the last floating vertebra and the iliac crest. |
| Total cholesterol, HDL cholesterol, LDL cholesterol and triglycerides | 6 months | assessed by blood sample analysis and combined to determine lipid profile |
| Insulin sensitivity | 6 months | assessed by oral glucose tolerance test (OGTT) |
| Systolic and Diastolic blood pressure | 6 months | assessed by auscultatory method with mercury sphygmomanometer |
| Physical activity level | 6 months | assessed by thigh-mounted accelerometer (ActivPAL™ micro) |
| Food consumption | 6 months | assessed by three 24-hour food recall in non-consecutive days (being one of the days on the weekend) |
| Visceral fat | 6 months | assessed by tomography |
| Peak oxygen consumption, as assessed by a cardiopulmonary exercise test | 6 months | — |
| Endothelial function | 6 months | assessed by flow-mediated vasodilatation (FMD) |
| Disease activity | 6 months | The activity of the disease, which will be impaired by safety, will be assessed by the presence of anti-dsDNA, using the ELISA technique and confirmation by indirect immunofluorescence in Crithidia luciliae and assessed by the questionnaire Systemic lupus erythematosus disease activity index 2000 (SLEDAI-2000). Total score ranges from 0 to 105. Higher scores represent higher disease activity. |
| Damage index | 6 months | assessed by Systemic Lupus International Collaborating Clinics/ American College of Rheumatology - Damage Index. Total score range from 0 (no damage) to 46 (maximum damage). |
| Global health status | 6 months | assessed by the Visual Analogic Scale (0 and 10 scale). Higher values represent worst global health status. |
| Patients' perceptions of the intervention | 6 months | assessed by focus group. A semi-structured script composed of open questions about intervention positive and negative points, barriers for physical activity practice and changes in food consumption, perceptions of health improvement or worsening (physical and psychological aspects), well-being, motivation to maintain the changes made, perspectives regarding health and disease. |
| Body mass index (BMI) | 6 months | assessed by weight (kg) and height (m) that will be combined to report BMI in kg/m\^2 |
| Quality of Life assessed by Systemic Lupus Erythematosus Quality of Life Questionnaire ( SLEQOL) [followed by its scale information in the Description] | 6 months | score ranges from 40 to 280 with higher scores represent worst life quality. |
| Physical functioning assessed by Timed-Stands | 6 months | evaluates the maximum number of stand-ups that a subject could perform from a standard height (i.e., 45 cm) armless chair within 30 s |
| Physical functioning assessed by Timed Up-and-Go | 6 months | evaluates the time required for the subject to rise from a standard arm chair, walk towards a line drawn on the floor three meters away, turn, return, and sit back down again |
| Physical functioning assessed by handgrip test | 6 months | Patients will be instructed to squeeze the dynamometer as hard as possible |
| Fatigue | 6 months | assessed by Fatigue Scale (FACIT). The final score can vary from 0 to 52, where higher final score representing higher level of fatigue. |
| Anxiety | 6 months | assessed by sub-scale of Hospital Anxiety and Depression Scale (HADS), called HADS-A. Total score ranges from 0 to 21. Where higher final score representing higher level. |
| Depression | 6 months | assessed by sub-scale of Hospital Anxiety and Depression Scale (HADS), called HADS-D. Total score ranges from 0 to 21. Where higher final score representing higher level. |
| Sleep quality assessed by data obtained from Actigraph (Actigraph GT3x) | 6 months | Data from actigraph will come as these measures: Total Sleep Time (hours/day), Sleep Efficiency (%), Sleep Onset Latency (min), and Wake After Sleep Onset (min), and this data will be considered to determine the sleep quality. |
| C-reactive protein (PCR) | 6 months | assessed by analysis of blood sample |
| Erythrocyte sedimentation rate | 6 months | assessed by analysis of blood sample |
| Inflammatory markers (blood biochemistry) | 6 months | assessed by serum cytokines |
| Follow-up | Between 7 and 28 months after the completion of the intervention | investigate the long-term effects of the intervention on maintenance of lifestyle behaviors and its effects on health |
| Quality of Life assesment assessed by the Short-Form Health Survey-36 (SF36) [followed by its scale information in the Description] | 6 months | maximum score is 100, with higher scores representing better life quality |
