Noise Induced Sleep Disturbance in Adult Population: Cross Sectional Study in Skopje Urban Centre
Journal Title: Macedonian Journal of Medical Sciences (MJMS) - Year 2009, Vol 2, Issue 3
Abstract
Aim. To evaluate sleep disturbance caused by environmental noise in residents of Skopje urban centre and to quantify the probability for sleep disturbance related to night-time noise exposure. Methods. Cross sectional study with noise measurements for determination of noise exposure indicator L night. A randomised sample was selected from adult population and directly interviewed with questionnaire for assessment of sleep disturbance. Results. 510 questionnaires were collected and the response rate was 72%, 8% of the population sample reported a high level of sleep disturbance and 18% reported a moderate level of sleep disturbance. The most frequent sources of noise were neighbourhood and road traffic. The most disturbed age group were individuals 51-65 years old, who were significantly more disturbed (p=0.010) than the age group of 41-50 years old. Differences in sleep disturbance were significant only for the group exposed to Lnight ≥ 56 dBA (Wald = 4.31; p = 0.04). Exposure to L night above 56 dBA had OR = 2.2 (95% CI 1.1 - 4.7) or double significant increase probability for sleep disturbance, compared with control group of subjects exposed to Lnight ≤ 45 dBA. Conclusion. Night time noise exposure above the established limit values significantly increased the risk for sleep disturbance. These findings induce necessity for reducing noise exposure, especially during night-time and for taking preventive measures.
