Abstract

Abstract: Introduction: Waste from swine industrial livestock operations (ILOs) produces air pollutants that have been associated with negative health outcomes among nearby residents. Methods: Using a repeated-measures design, we assessed the impact of odor emissions on sleep duration and awakenings, important components and determinants of health and quality-of-life. Study participants from 16 residential communities in eastern North Carolina hosting swine ILOs, from 2003 to 2005, completed twice-daily diaries in which they rated the strength of hog odors and indicated whether they were asleep or awake per hour for two weeks. Simultaneously, a monitoring trailer placed in a central location in each community measured the atmospheric concentration of hydrogen sulfide (H2S). Subject-conditional fixed-effects regression models were used to estimate associations between two markers of swine ILO pollutant exposures (H2S and swine odor) and two self-reported sleep outcomes (nightly sleep duration and awakening from sleep). Results: Among 80 participants, nightly (across a 12-hour period) swine odor was associated with lower-nightly sleep duration (mean difference = -14.3 minutes, 95% confidence interval -25.0 to -3.3 minutes) compared to odor-free nights and detection of nightly hydrogen sulfide was associated with a 23% increased hazard of awakening (Hazard ratio = 1.23, 95% confidence interval 0.98 to 1.55) compared to nights with no detection of hydrogen sulfide. Conclusion: These results suggest that emissions reductions and odor abatement are important public health goals in designing policy and technology solutions to the problems of livestock production and waste management.
