Noise and sleep quality: study among physical education instructors

Abstract

This study investigated the association between noise and impaired sleep quality in 150 physical education instructors, in bodybuilding gyms. Two questionnaires were applied: evaluation of subjective sleep quality and analysis of explanatory variables. Noise exposure was analyzed. For the data analysis, was used the technique of non-conditional logistic regression, to obtain the values of the adjusted odds ratios (OR) of the significant variables. Two proper adjustment models stood out. The first model presented the significant variables: incorrect performance of the meals (OR = 2.58, 95% CI 1.08 to 6.02); skin color – black ou brown (OR = 0.53, 95% CI 0.25 to 1.12) and exposure to noise level above or equal to 80 dB(A) (OR = 1.90; 95% CI 0.87 to 4.12). The second model presented the significant variables: incorrect performance of the meals (OR = 2.35, 95% CI 0.1 to 5.56); exposure level standardized above or equal to 80 dB(A) (OR = 2.03, 95% CI 0.92 to 4.47) and use 0of drugs for depression/anxiety (OR = 0.26; 95% CI 0.53 to 1.33). This research identified the variables that were significantly associated with impaired sleep quality, as exposure to noise, contributing to the adoption of preventive measures.
