Efeitos de uma intervenção de promoção de saúde mista sobre o nível de atividade física em servidores técnico-administrativos da Universidade Federal de Pelotas: estudo INVISTA

Abstract

The thesis consists of two main articles, the first being a systematic review on physical activity counseling and the second a study with original data collected from a health intervention. This review is published in an online journal, and presents a synthesis of studies on the subject, published between 2010 and 2020. The studies analyzed in this review reveal that health education through counseling was effective in promoting PA and health, supporting actions to prevent and combat the epidemic of physical inactivity. The original study evaluated the effect of a mixed health promotion intervention, with online advice on the level of physical activity (PA) and reduction of sedentary behavior (SB) of Technical-Administrative Educational Servers (TAEs), at the Federal University of Pelotas (UFPel). It is an research consortium INVISTA (Intervention for a Healthy Lifestyle and Active Work), which used advice in the form of lectures and folders related to nutritional aspects, PA and reduction of musculoskeletal pain (MSP). The objective of this study was to evaluate the effectiveness of this intervention on the level of PA. The project was approved by the Research Ethics Committee of the Higher School of Physical Education at UFPel, under opinion: 3,785,347. Servers were invited to participate in the INVISTA study and those who responded to the survey at baseline and enrolled in the course were considered Intervention Group (IG: 20). TAEs who only answered the questionnaire, but did not participate in the intervention, formed the Control Group (CG: 73). Counseling was carried out remotely, sending digital posters, and also, through eight lectures held every 15 days, through the e-Projeto-UFPel platform, from April to July 2022. Lectures, a summary of the topics addressed in the lectures and posters with advice on PA, healthy eating and MP were sent by email and made available on the course platform. A total of 93 TAEs answered the questionnaire at baseline and 83 after the intervention. There was a significant change in the way the servers work, predominantly hybrid at the beginning of the study to mostly presential, in the post-intervention. The results showed that the INVISTA intervention was not enough to modify PA in minutes/week in the IG, compared to the CG. We also observed an increase in sedentary behavior post-intervention. The change in work modality may have influenced these health behaviors, with those active in the pre-intervention period in the IG being 65.0% and in the CG 67.1%, in the post-intervention period they were active in the IG 45.0%. and in CG 57.5. This study tested remote intervention strategies in occupational health, with a population of technical-administrative employees.
