Description:Purpose:
The objective of this article is to review recent literature on the implications of agricultural factors including pesticides, animal/livestock production facilities, agricultural dust, endotoxin, biomass/crop burning, and nutritional factors with respiratory health, particularly in relationship to asthma and wheeze, of rural residents.
Methods:
PubMed, Embase, and CINAHL literature searches of years 2016–2021 were conducted with librarian assistance. Terms searched were rural population, rural health, small town, farming, agriculture, environmental pollution, biomass, pesticides, pollution, asthma, pulmonary disease, chronic obstructive pulmonary disease, chronic airflow obstruction, and adult. Articles were selected for inclusion after the literature search based on topic fit by author review.
Results:
Several studies suggest increased risk for asthma or wheeze with certain rural exposures, particularly for pesticides, livestock production facilities, agricultural dust, and biomass and crop burning. Endotoxin exposure yields variable consequences and may vary with timing of exposure. Studies also suggest a possible respiratory protective effect for specific nutritional factors, including a high omega-3 fatty acid diet and unpasteurized milk consumption.
Conclusion:
A complex network of environmental factors exist which may have detrimental effects on the respiratory health of rural residents. These factors include, but are not limited to, pesticides, livestock and animal production facilities, agricultural dust, endotoxin, and biomass and crop burning. In contrast, several dietary factors have been suggested as potentially protective for respiratory health in rural populations. Further investigations into these agricultural factors to prevent or minimize adverse respiratory effects in rural populations is warranted.
