Environmental Concerns for Children with Asthma on the Navajo Nation.

ABSTRACT: RATIONALE:Navajo children living on the reservation have high rates of asthma prevalence and severity. Environmental influences may contribute to asthma on the Navajo Nation and are inadequately understood. OBJECTIVES:We performed a comprehensive, integrative literature review to determine the environmental factors that may contribute to increased asthma prevalence and severity among Navajo children living on the reservation. METHODS:A systematic search was conducted in four databases regarding the environmental risk factors for asthma in Navajo children living on the reservation. Relevant studies between 1990 and 2017 were examined. Nonexperimental literature was also integrated into the review to describe the environmental injustices that have historically, disproportionately, and systematically affected the Navajo people, thus contributing to respiratory disparities among Navajo children. RESULTS:Eight studies met inclusion criteria for systematic review; however, limited research regarding environmental risk factors specific to asthma and Navajo children living on the reservation was identified. Our integrative review indicated both indoor and outdoor environmental risk factors commonly found on the Navajo reservation appear to be important determinants of asthma. CONCLUSIONS:Future research should examine indoor and outdoor air pollution from wood-burning stoves and cook stoves, coal combustion, tobacco and traditional ceremonial smoke, diesel exhaust exposure from long bus rides, indoor allergens, ambient pollutants, and regional dusts. Comprehensive mitigation efforts created in partnership with the Navajo Nation are necessary to address less-recognized risk factors as well as the common risk factors known to contribute to increased childhood asthma prevalence and severity.

Project description:Background:American Indians and Alaska Natives experience diet-related health disparities compared with non-Hispanic whites. Navajo Nation's colonial history and remote setting present unique challenges for healthy food access. Objective:This study aims to understand the impact of the Healthy Navajo Stores Initiative (HNSI) on fruit and vegetable purchasing on Navajo Nation. Methods:We conducted a cross-sectional survey of 692 customers shopping at 28 convenience stores, trading posts, and grocery stores on Navajo Nation. Individual- and household-level sociodemographic data and food purchasing behaviors were collected. Descriptive and bivariate analyses for customers' individual- and household-level characteristics were conducted using chi-squared tests. The impact of individual-, household-, and store-level factors on fruit and vegetable purchasing was assessed using multiple logistic regression modeling. Results:Store participation in the HNSI was significantly associated with customers' purchase of produce. Customers experienced 150% higher odds of purchasing produce if they shopped in participating stores, compared with nonparticipating stores (P < 0.001). Store type was strongly associated with customers' purchase of fruits or vegetables. Customers shopping at a grocery store had 520% higher odds of purchasing produce than did customers shopping at convenience stores (P < 0.001). Customers shopping at trading posts had 120% higher odds of purchasing fruits or vegetables than did customers shopping at convenience stores (P = 0.001). Conclusions:Our findings reveal increased produce purchasing at stores participating in the HNSI. Customers were significantly more likely to purchase fruits or vegetables in stores enrolled in a healthy store intervention than in nonenrolled stores, after controlling for quantity of produce stocked and store type. Customers shopping in grocery stores and trading posts were significantly more likely to purchase produce than customers shopping in convenience stores. These findings have implications for food access in rural tribal communities.
