Efeito do ultrassom de baixa frequência utilizado para redução de adiposidade localizada sobre o perfil lipídico em mulheres

Abstract

Low-frequency ultrasound (LFUS) has been used for body contouring as an effective and non-invasive procedure, however, possible changes in plasma lipid profile after treatment are not well understood. The aim of this study was to evaluate the use of USBF on the behavior of lipid profile and blood lipid biomarkers. Twenty women aged 24 to 45 years were randomly divided into 2 groups: USBF Group (n=10; treated with USBF) and Placebo Group (n=10; treated with USBF turned off). Laboratory blood tests were performed before the procedures (T1) and 48 hours after the procedures (T2) to evaluate the lipid profile with biomarkers: triglycerides, cholesterol, HDL, LDL and non HDL. The VIBRIA MAXX equipment (HTM ELECTRONICS, Amparo, SP, Brazil) was used, with a frequency of 40 KHz, continuous mode and intensity of 3 W/cm². The application was performed by scanning, for about 3 minutes in each quadrant, totaling 30 minutes of treatment time. The interventions were performed 3 times a week, with 48-hour intervals between sessions, until a total of 10 sessions. In the placebo group, the procedures were the same, however, the USBF equipment remained turned off during the application. A quality of life questionnaire for body treatment adapted from Body-QoL® was applied after the interventions. The laboratory evaluations showed a significant increase in LDL only in the USBF group (p < 0.05), however, the values remained within the normal range. The results of this study indicated that the analysis of body satisfaction using the BODY QUOL® questionnaire was effective. The domain: body satisfaction, of the BODY QUOL® questionnaire showed a statistically significant difference (p < 0.05) between the group treated with USBF and the control group. Therefore, we can conclude that the use of USBF has been shown to be a safe and effective technique for the treatment of localized fat, as it maintained lipid profile levels within the normal range and improved the quality of life of patients who underwent the technique.
