Lower back pain profile in restaurant workers at a public university in southern Brazil

Abstract

The tasks that workers in university restaurants (URs) perform involves repetitive movements of the back, lifting excessive weight, remaining in a standing posture for prolonged periods of time, and, thus, an evaluation of the lumbar region of these workers is indicated. Therefore, the objective of this study was to outline the profile of lower back pain in workers from the URs of a Public University in the South of Brazil. This is a cross-sectional, observational, quantitative study, in which participants aged 18 to 59 years, of both sexes, who performed some function within the restaurants of a university in southern Brazil and who reported the presence of lower back pain were selected. Participants were evaluated by a sociodemographic questionnaire, a visual analogue scale (VAS) for pain, a range of motion (ROM) of the lumbar spine evaluation, and the Brazilian Start Back Screening Tool (SBST) questionnaire. Results are presented as absolute and relative frequencies, with a Spearman correlation, and numerical variables as mean and standard deviation or median, minimum, and maximum. Twenty-eight participants were included in the study, 71.4% of whom were women, with a mean age of 36.3 (±10.8) years old. The report of pain above 4 in the VAS was 71.4% of the participants and all had a decrease in ROM in all movements evaluated in the lumbar spine. Most (71.4%) had low risk for psychosocial factors by SBST. The profile of restaurant workers at the evaluated university is characterized by being primarily performed by women, and these workers presented severe pain and limited joint movements in their lumbar region.
