简要总结
This study evaluates the association between sedentary behaviour, physical activity, and the cardiometabolic health of Multiple Sclerosis via several cardiovascular, metabolic and anthropometric parameters.
详细描述
Multiple sclerosis (MS) is an autoimmune, inflammatory and neurodegenerative disorder of the central nervous system, predominantly affecting young to middle-aged adults. The disease manifests in a broad spectrum of associated sensory, motor and psychological dysfunction, and there is a large variability in symptoms between (and within) persons with MS (PwMS). This can (partly) be explained by the co-existence of cardiometabolic (CM) diseases, such as hypertension, dyslipidaemia, insulin resistance or diabetes. More specifically, the presence of one or more of these CM diseases has been associated with a worsening of disability, independent of the timing of their development (at MS symptom onset, diagnosis, or later in the disease course). Therefore, the prevention and/or treatment of these CM comorbidities also warrant attention in MS rehabilitation.
In most studies PwMS and HC were matched on age, sex, height and weight. Importantly, differences in physical activity (PA) and sedentary behaviour (SB) were never taken into account, while this might be a relevant matching risk factor between groups. Moreover, Ranadive et al. found a significant worse vascular function in PwMS compared to HC, but differences were accounted for by low PA in PwMS. This might mean that PwMS can completely attenuate their increased CM risk by increasing their PA. However, this conclusion was only based on a statistical correction, there was a large difference in PA between groups and other confounding factors (such as PA intensity, smoking and nutrition intake) were not taken into account.
Therefore, the present study aims to investigate the relation between CM health and different intensities of PA and SB in PA-matched PwMS and HC. When CM health is comparable between PwMS and HC with similar PA levels, this shows the importance of including PA and SB measures and interventions as early as possible in MS treatment before automatically starting CM medication because PwMS are known to have multiple risk factors.

结局指标
主要结局
Waist circumference
时间窗: After 7 days of physical activity monitoring
Waist circumference will be measured to the nearest 0.1cm using a flexible metric measuring tape with participants barefoot (in underwear) in standing position. Waist circumference is measured at the midpoint between the lower rib margin and the top of the iliac crest.
Hip circumference
时间窗: After 7 days of physical activity monitoring
Hip circumference will be measured to the nearest 0.1cm using a flexible metric measuring tape with participants barefoot (in underwear) in standing position. Hip circumference is measured at the widest circumference of the hip at the level of the greater trochanter.
Concentration of total cholesterol
时间窗: After 7 days of physical activity monitoring
Blood analysis
Concentration of low density lipoprotein cholesterol (LDL-cholesterol)
时间窗: After 7 days of physical activity monitoring
Blood analysis
Respiratory gas exchange ratio (RER)
时间窗: After 7 days of physical activity monitoring
Cardiopulmonary exercise test on an electronically braked cycle ergometer is performed. With the aid of continuous pulmonary gas exchange analysis RER is collected breath-by-breath and averaged every ten seconds.
Concentration of Insulin
时间窗: After 7 days of physical activity monitoring
Blood analysis of insulin during OGTT
Concentration of high density lipoprotein cholesterol (HDL-cholesterol
时间窗: After 7 days of physical activity monitoring
Blood analysis
metabolic syndrome (MetS) risk score
时间窗: After 7 days of physical activity monitoring
A continuous metabolic syndrome risk score will be calculated using the waist circumference, HDL concentration, systolic blood pressure, triglycerides and fasting glucose levels, as described by Gurka et al. (2014). A higher score indicates worse health. Because this is a continuous scale, there is no minimum and maximum value.
Body weight
时间窗: After 7 days of physical activity monitoring
Body weight (in underwear) is determined using a digital-balanced weighting scale to the nearest 0.1 kg
Height
时间窗: After 7 days of physical activity monitoring
Body height is measured to the nearest 0.1cm using a wall-mounted Harpenden stadiometer, with participants barefoot
DEXA (Dual Energy X-Ray)
时间窗: After 7 days of physical activity monitoring
body fat mass and lean tissue mass using Dual Energy X-ray Absorptiometry
Concentration of glucose
时间窗: After 7 days of physical activity monitoring
Concentration of glucose measured in blood analysis during OGTT
Concentration of triglyceride
时间窗: After 7 days of physical activity monitoring
Blood analysis
Concentration of inflammatory markers
时间窗: After 7 days of physical activity monitoring

Reactive hyperaemia index (RHI)
时间窗: After 7 days of physical activity monitoring
Vascular endothelial function will be assessed by non-invasive peripheral arterial tonometry using the EndoPAT™ 2000 device. The reactive hyperaemia index reflects the reactive hyperaemia response, and is calculated as the ratio of the average peripheral arterial tone (PAT) signal in the posthyperemic phase to the baseline PAT signal in the occluded arm, with normalization to the ratio of the PAT signal in the control arm to account for any systemic hemodynamic changes.
Homeostatic model assessment for insulin resistance (HOMA-IR)
时间窗: After 7 days of physical activity monitoring
An oral glucose tolerance test will be performed for assessment of whole body insulin sensitivity using the homeostatic model assessment for insulin resistance (HOMA-IR). The HOMA-IR is calculated from the fasting insulin and glucose concentration.sensitivity and beta cell function. The following parameters are calculated: homeostatic model assessment for insulin resistance, whole-body insulin sensitivity index, insulinogenic index and the area under the curve for glucose and insulin.
Insulinogenic index
时间窗: After 7 days of physical activity monitoring
An oral glucose tolerance test will be performed for assessment of beta cell function by calculation of the insulinogenic index. The insulinogenic index is calculated from both insulin and glucose concentrations.
Cardiac autonomic function
时间窗: After 7 days of physical activity monitoring
Cardiac autonomic function will be operationalized as heart rate variability by means of continuous beat-to-beat heart rate signal measurements. time domain and frequency domain analysis of the R-R intervals will be performed
Systolic and Diastolic blood pressure
