OBJECTIVES. Little is known about the health effects of living in close proximity to industrial swine operations. We assessed the relationship between estimated exposure to airborne effluent from confined swine feeding operations and asthma symptoms among adolescents who were aged 12 to 14 years. METHODS. During the 1999–2000 school year, 58169 adolescents in North Carolina answered questions about their respiratory symptoms, allergies, medications, socioeconomic status, and household…

Environmental Exposure to Confined Animal Feeding Operations and Respiratory Health of Neighboring Residents

The number of animal houses was a predictor of self-reported wheeze and decreased forced expiratory volume in 1 second, but not allergic rhinitis or specific sensitization, which may contribute to the burden of respiratory disease among their neighbors.

Air Pollution, Lung Function, and Physical Symptoms in Communities Near Concentrated Swine Feeding Operations

Pollutants measured near hog operations are related to acute physical symptoms in a longitudinal study using analyses that preclude confounding by time-invariant characteristics of individuals.

Estimated time-varying exposures to air emissions from animal feeding operations and childhood asthma.

Ambient Ammonia Exposures in an Agricultural Community and Pediatric Asthma Morbidity

Ammonia’s association with acute lung function decrements in children with asthma in the surrounding community may be causal or, alternatively, ammonia may be a marker for other pollutants from animal feeding operations associated with respiratory effects.

Air pollution from livestock farms, and asthma, allergic rhinitis and COPD among neighbouring residents

Investigation of associations between indicators of air pollution from livestock farms and asthma, allergic rhinitis and chronic obstructive pulmonary disease (COPD) among neighbouring residents found indicators of pollution were inversely associated with respiratory morbidity among neighbouringResidents.

Effects on Pulmonary Health of Neighboring Residents of Concentrated Animal Feeding Operations: Exposure Assessed Using Optimized Estimation Technique

Higher exposed participants were more likely to be sensitized against ubiquitous allergens as compared to lower exposed subjects and showed a significantly lower forced expiratory volume in 1 second.

Asthma prevalence and morbidity among rural Iowa schoolchildren.

Ecological associations between asthma prevalence and potential exposure to farming

The findings of this study are consistent with the hypothesis that certain farm exposures are protective against childhood asthma, and further research with individual-level data is needed to identify the specific protective exposures.

Relative scarcity of asthma and atopy among rural adolescents raised on a farm.

Current wheeze, airways hyperresponsiveness (AHR), and skin test positivity to inhaled allergens were all significantly less common among adolescents raised on the farm and these differences were especially pronounced in girls.

Respiratory morbidity in relationship to farm characteristics in swine confinement work: possible preventive measures.

To decrease the risk of respiratory morbidity the following preventive measures are proposed: discouragement of the use of disinfectants and of wood-shavings as bedding, and promotion of theUse of mechanical ventilation systems.

Asthma and Farm Exposures in a Cohort of Rural Iowa Children

The high prevalence of rural childhood asthma and asthma symptoms underscores the need for asthma screening programs and improved asthma diagnosis and treatment, and suggests theneed for awareness and prevention measures and more population-based studies to further assess environmental and genetic determinants of asthma among farm children.

Presence of asthma risk factors and environmental exposures related to upper respiratory infection-triggered wheezing in middle school-age children.

URI-TW in middle school children is most associated with reported allergen sensitivity, relative to other asthma risk factors and environmental exposures, and is useful in developing assessment, screening, and targeting strategies to improve asthma and wheezing management in children.

Who gets diagnosed with asthma? Frequent wheeze among adolescents with and without a diagnosis of asthma.

Undiagnosed frequent wheezing was independently associated with female gender, current smoking, exposure to household smoke, low socioeconomic status, allergies, and African American, Native American, and Mexican American race/ethnicity.

Occupational exposure and lung function measurements among workers in swine confinement buildings.

It is suggested that exposure to dust in swine confinement buildings may lead to respiratory impairment but further studies on larger population samples and different exposure conditions are required.

Intensive livestock operations, health, and quality of life among eastern North Carolina residents.

Quality of life was similar in the control and the community in the vicinity of the cattle operation but greatly reduced among residents near the hog operation, and respiratory and mucous membrane effects were consistent with the results of studies of occupational exposures among swine confinement-house workers and previous findings for neighbors of intensive swine operations.

Effects of tobacco smoke exposure on asthma prevalence and medical care use in North Carolina middle school children.

Even at low levels of exposure, childhood cigarette smoking and ETS are independently associated with asthmatic symptoms.
