Objective: To evaluate the effect of a mHealth intervention, at 3 and 12 months, on arterial stiffness and central hemodynamic parameters in a sedentary population with overweight and obesity. Methods: Randomised controlled clinical trial (Evident 3 study). 253 subjects were included: 127 in the intervention group (IG) and 126 in the control group (CG). The IG subjects were briefed on the use of the Evident 3 app and a smart band (Mi Band 2, Xiaomi) for 3 months to promote healthy lifestyles. All measurements were recorded in the baseline visit and at 3 and 12 months. The carotid-femoral pulse wave velocity (cfPWV) and the central hemodynamic parameters were measured using a SphigmoCor System® device, whereas the brachial-ankle pulse wave velocity (baPWV) and the Cardio Ankle Vascular Index (CAVI) were measured using a VaSera VS-2000® device. Results: Of the 253 subjects who attended the initial visit, 237 (93.7%) completed the visit at 3 months of the intervention, and 217 (85.3%) completed the visit at 12 months of the intervention. At 12 months, IG showed a decrease in peripheral augmentation index (PAIx) (−3.60; 95% CI −7.22 to −0.00) and ejection duration (ED) (−0.82; 95% CI −1.36 to −0.27), and an increase in subendocardial viability ratio (SEVR) (5.31; 95% CI 1.18 to 9.44). In CG, cfPWV decreased at 3 months (−0.28 m/s; 95% CI −0.54 to −0.02) and at 12 months (−0.30 m/s, 95% CI −0.54 to −0.05), central diastolic pressure (cDBP) decreased at 12 months (−1.64 mm/Hg; 95% CI −3.19 to −0.10). When comparing the groups we found no differences between any variables analyzed. Conclusions: In sedentary adults with overweight or obesity, the multicomponent intervention (Smartphone app and an activity-tracking band) for 3 months did not modify arterial stiffness or the central hemodynamic parameters, with respect to the control group. However, at 12 months, CG presented a decrease of cfPWV and cDBP, whereas IG showed a decrease of PAIx and ED and an increase of SEVR.2022http://zaguan.unizar.es/record/12119410.3390/nu14224758http://zaguan.unizar.es/record/121194oai:zaguan.unizar.es:121194info:eu-repo/grantAgreement/ES/ISCIII/PI16-00101info:eu-repo/grantAgreement/ES/ISCIII/PI16-00170info:eu-repo/grantAgreement/ES/ISCIII/PI16-00421info:eu-repo/grantAgreement/ES/ISCIII/PI16-00659info:eu-repo/grantAgreement/ES/ISCIII/PI16-00765info:eu-repo/grantAgreement/ES/ISCIII-RICAPPS/RD21-0016-0005info:eu-repo/grantAgreement/ES/ISCIII-RICAPPS/RD21-0016-0009info:eu-repo/grantAgreement/ES/ISCIII-RICAPPS/RD21-0016-0010info:eu-repo/grantAgreement/ES/ISCIII-RICAPPS/RD21-0016-0025info:eu-repo/grantAgreement/ES/MICINN-ISCIII-ERDF-ESF/FI17-00040-Investing in your futureinfo:eu-repo/grantAgreement/ES/MICINN-ISCIII-ERDF-ESF/PI16-00952-Investing in your futureNutrients 14, 22 (2022), 4758 [20 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
