Background: Transportation noise leads to cardiovascular diseases. One pathway could relate to noise annoyance, impaired sleep, and reduced physical activity, which contribute to cardiometabolic diseases. We investigated the association between residential transportation noise annoyance and physical activity, cross-sectionally and longitudinally. Methods: We assessed 3,622 participants (age 38-80) that attended all visits (years 1991, 2001, and 2011) of the population-based Swiss SAPALDIA cohort. Physical activity was defined as being sufficiently active (>150 metabolic equivalents, MET-min/week, of self-reported moderate and vigorous activities) and as a 4-category outcome for remaining active/inactive or becoming active/inactive from visit 2 to 3. Noise annoyance was reported on an ICBEN-type 11-point scale for a) night-time road traffic, railway, aircraft (visit 3), b) 24-hour transportation noise (all visits), and c) long-term transportation noise, average of b) up to current visit. We used multivariate and multinomial logistic regression for cross-sectional and longitudinal analyses, respectively, adjusting for age, sex, socioeconomic status, lifestyles, body mass index, and consecutively for air pollution annoyance, study area, comorbidities, sleep deprivation, and noise sensitivity. We evaluated effect modification by sex, sleep deprivation, and noise sensitivity. Results: 16.4%, 7.4%, 3.1%, and 1.1% were annoyed (score ≥5) by transportation and night-time road, aircraft, and railway noise (visit 3), respectively. Cross-sectionally, noise annoyance to night-time road traffic and to transportation yielded a statistically significant 4% reduction in being physically active at visit 3. In longitudinal analyses, long-term transportation noise annoyance at visit 2 prevented from becoming or remaining active at visit 3 at equal rates (for fully adjusted model: RRs=0.98, 95%CI: 0.96-1.00, per 1-annoyance point) compared to remaining inactive. Estimated effect sizes were robust to all adjustment sets. Associations tended to be stronger among individuals reporting sleep deprivation. Conclusions: Transportation noise annoyance, especially from night-time road traffic, could contribute to cardiometabolic diseases through physical inactivity, particularly among individuals with impaired sleep.
