Description

Obesity is a chronic and multifactorial disease, physiologically characterized by excessive storage of body fat, which may have as a risk factor certain social reasons, lifestyle, inappropriate food consumption, extremely restrictive diets, poor relationship with food, low levels of physical activity, among other aspects. (two) In Brazil, it is estimated that 6 in 10 Brazilians are overweight, which represents 96 million overweight people in the country. Furthermore, according to the World Obesity Federation, by the year 2035, 1 in 4 people (almost two billion) will live with obesity (BMI above 30 kg/m2). Therefore, obesity is the second most important risk factor for the global burden of chronic non-communicable diseases (NCDs), such as cardiovascular diseases , high blood pressure, diabetes, colon, rectum, breast cancer and cirrhosis. However, absence from work, psychological disorders, low self-esteem and social isolation require both a physical and psychological treatment perspective.

A population widely susceptible to weight gain are postmenopausal women. In a physiological context, postmenopause is the last phase of the climacteric period, the reproductive to non-reproductive period, beginning 12 months after the woman's last menstruation, and ending, on average, at 65 years of age. Evidence indicates that 50% of the female population, at this time, has metabolic syndrome, a strong tendency to accumulate visceral abdominal adiposity, seen by an increased abdominal circumference, changes in bone metabolism and greater susceptibility to chronic non-communicable diseases. Among the chronic diseases that develop during menopause are those related to the heart, with high blood pressure, diabetes and coronary disease being the protagonists of this unfavorable scenario, a fact already evidenced by some recent studies that point to women in menopause with a higher prevalence of central arterial stiffness.

Arterial stiffness is the mechanical distension stress induced by anterograde and retrograde systolic waves, which reduces the thickness and fragments elastin fibers, replaced by collagen and protein matrix, with less capacity to dampen pulse wave pressures, increasing the stiffness of the arterial walls and the speed of anterograde and retrograde (or reflex) pulse waves.

Arterial stiffness is assessed using Pulse Wave Velocity (PWV), an important marker of central artery stiffness, considered an early predictor of risk for hypertension and CVD, when PWV > 10 m/s. For every 1 m/s increase in PWV, there is an increase in the risk of cardiovascular death, cardiovascular events and death from all causes of around 14-15%.

A meta-analysis has already demonstrated that reducing body weight (average of 8% of initial body weight), achieved through diet and lifestyle changes, improved PWV. Both diet and regular exercise have an effect on PWV. reduction in PWV as a consequence of weight reduction, and reducing >7% of initial body weight has a more robust effect.

Therefore, the management of body weight during menopause, as well as other aspects of women's health, requires a broad spectrum of transdisciplinary action, with dietary and non-dietary interventions as psychological support and encouragement for a more active life. In this context, new technologies represent a comprehensive and accessible alternative for the use of multidisciplinary tools in body weight management, since technological advances have increasingly provided non-invasive methods for health management.

Therefore, the SlimTrack platform presents tools that help both in facing thoughts and emotions that are harmful to long-term weight loss, and with physical activities that promote body self-awareness, meeting the needs of physical activity, and dietary guidelines, contributing to a change in Lifestyle. At this moment, the platform is in the development process through a notice Call CNPq/SEMPI/MCTI nº 021/2021 - RHAE Program - Line 2 - Start-Ups, Process: 424509/2021-0 Creation of an interactive digital platform for the management and treatment of overweight and obesity - Non-Dietary Weight Loss (END), coordinated by Dr. Cláudia Fetter and Dr. Juliana Bertoletti. The first phase or MVP ( minimum viable product ) is made up of 3 stages of 7 days (total 21 days), is in the finalization phase to be made available to the public, scheduled for October 2023.

Therefore, in view of the above, as well as the current health scenario and its demands, especially regarding obesity and risk factors associated with health, this project intends to evaluate the effects of the SlimTrack ® Platform on adherence to the diet, variation body weight, anthropometric variables and arterial stiffness in postmenopausal women.
