Housing and Neighborhood Characteristics and Latino Farmworker Family Well-Being

Pesticide Exposure among Latinx Children in Rural Farmworker and Urban Non-Farmworker Communities: Associations with Locality and Season

This study uses repeated measures to document the pesticide exposure of rural and urban Latinx children (age eight at baseline), and to compare these children in terms of the frequency and concentration of their exposure to a large set of pesticides, accounting for season. We used silicone wristbands worn for one week up to ten times at quarterly intervals from 2018 to 2022 to assess pesticide exposure in children from rural farmworker (n = 75) and urban non-farmworker (n = 61) families. We determined the detection and concentrations (ng/g) of 72 pesticides and pesticide degradation products in the wristbands using gas chromatography electron capture detection and gas chromatography mass spectrometry. The most frequently detected pesticide classes were organochlorines, pyrethroids, and organophosphates. Controlling for season, organochlorine or phenylpyrazole detections were less likely for rural children than for urban children. Detections of organochlorines, pyrethroids, or organophosphates were lower in spring and summer versus winter. Controlling for season, urban children had greater concentrations of organochlorines, while rural children had greater concentrations of pyrethroids and Chlorpyrifos. Pesticide concentrations were lower in winter and spring compared with summer and fall. These results further document that pesticides are ubiquitous in the living environment for children in vulnerable, immigrant communities.

A decade of research on housing and health: a systematic literature review

This paper provides a systematic review of the evidence linking housing and health. This involved a review of 59 peer-reviewed journal papers, that included case studies on the health impacts of housing and were published in English, in the past decade (2010-2020). Our systematic review of the literature suggested most of the research on the health impacts of housing employed quantitative methodology, were conducted in the Global North and were published in Medical and Health Sciences journals. Research findings demonstrated four key areas through which housing impacts health: neighbourhood or context, physical building, housing market and housing policy. This paper provides valuable information to researchers for future research directions on the associations between housing and health and to decision-makers and planners for planning healthy cities.

Global food systems transitions have enabled affordable diets but had less favourable outcomes for nutrition, environmental health, inclusion and equity

Over the past 50 years, food systems worldwide have shifted from predominantly rural to industrialized and consolidated systems, with impacts on diets, nutrition and health, livelihoods, and environmental sustainability. We explore the potential for sustainable and equitable food system transformation (ideal state of change) by comparing countries at different stages of food system transition (changes) using food system typologies. Historically, incomes have risen faster than food prices as countries have industrialized, enabling a simultaneous increase in the supply and affordability of many nutritious foods. These shifts are illustrated across five food system typologies, from rural and traditional to industrial and consolidated. Evolving rural economies, urbanization and changes in food value chains have accompanied these transitions, leading to changes in land distribution, a smaller share of agri-food system workers in the economy and changes in diets. We show that the affordability of a recommended diet has improved over time, but food systems of all types are falling short of delivering optimal nutrition and health outcomes, environmental sustainability, and inclusion and equity for all. Six ‘outlier’ case studies (Tajikistan, Egypt, Albania, Ecuador, Bolivia and the United States of America) illustrate broad trends, trade-offs and deviations. With the integrated view afforded by typologies, we consider how sustainable transitions can be achieved going forward.

Altered Default Mode Network Associated with Pesticide Exposure in Latinx Children from Rural Farmworker Families

Pesticide exposure has been associated with adverse cognitive and neurological effects. However, neuroimaging studies aimed at examining the impacts of pesticide exposure on brain networks underlying abnormal neurodevelopment in children remain limited. It has been demonstrated that pesticide exposure in children is associated with disrupted brain anatomy in regions that make up the default mode network (DMN), a subnetwork engaged across a diverse set of cognitive processes, particularly higher-order cognitive tasks. This study tested the hypothesis that functional brain network connectivity/topology in Latinx children from rural farmworker families (FW children) would differ from urban Latinx children from non-farmworker families (NFW children). We also tested the hypothesis that probable historic childhood exposure to pesticides among FW children would be associated with network connectivity/topology in a manner that parallels differences between FW and NFW children. We used brain networks from functional magnetic resonance imaging (fMRI) data from 78 children and a mixed-effects regression framework to test our hypotheses. We found that network topology was differently associated with the connection probability between FW and NFW children in the DMN. Our results also indicated that, among 48 FW children, historic reports of exposure to pesticides from prenatal to 96 months old were significantly associated with DMN topology, as hypothesized. Although the cause of the differences in brain networks between FW and NFW children cannot be determined using a cross-sectional study design, the observed associations between network connectivity/topology and historic exposure reports in FW children provide compelling evidence for a contribution of pesticide exposure on altering the DMN network organization in this vulnerable population. Although longitudinal follow-up of the children is necessary to further elucidate the cause and reveal the ultimate neurological implications, these findings raise serious concerns about the potential adverse health consequences from developmental neurotoxicity associated with pesticide exposure in this vulnerable population.

Rural Latino health and the built environment: a systematic review

Objective: This study systematically reviewed literature examining the influence of the rural built environment on Latinos' health outcomes and behaviour in the United States. A secondary aim of the study was to identify strategies developed to address challenges in the rural built environment affecting Latinos' health.Design: This study followed the reporting guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Articles included in the final analysis clearly linked Latino health outcomes to characteristics of the rural built environment.Results: Of the nearly 2,500 articles identified in the initial search, the final review included approximately 146 full-text sources. The majority of the articles focused on aspects of Latinos' physical (n = 68), behavioural (n = 43), and mental health (n = 23).Conclusions: Rural Latino neighbourhoods in the United States possess limited access to health care, internet, transportation, and recreation infrastructure, which negatively impacts health outcomes and behaviours. Strategies developed to mitigate these issues include but are not limited to: the use of telecommunications to distribute health information; the use of community health workers and mobile clinics to increase awareness and availability of select health services; the use of worksite trainings and adaptations to the workplace; and the promotion of safety net programmes, such as the Supplemental Nutrition Programme for Women, Infants and Children (WIC). This review supports the need for a more robust research agenda documenting the health experiences of rural Latinos of various nationalities, age groups, and genders.

Pesticide exposure among Latinx children: Comparison of children in rural, farmworker and urban, non-farmworker communities

Personal pesticide exposure is not well characterized among children in vulnerable, immigrant communities. We used silicone wristbands in 2018-2019 to assess pesticide exposure in 8 year old Latinx boys and girls in rural, farmworker families (n = 73) and urban, non-farmworker families (n = 60) living in North Carolina who were enrolled in the PACE5 Study, a community-based participatory research study. We determined the detection and concentrations (ng/g) of 75 pesticides and pesticide degradation products in the silicone wristbands worn for one week using gas chromatography electron capture detection and employed gas chromatography mass spectrometry. Differences by personal and family characteristics were tested using analysis of variance or Wilcoxon Rank Sum tests when necessary. Pesticide concentrations above the limit of detection were analyzed, and reported as geometric means and 95% confidence intervals (CI). The most frequently detected pesticide classes were organochlorines (85.7%), pyrethroids (65.4%), and organophosphates (59.4%), with the most frequently detected specific pesticides being alpha-chlordane (69.2%), trans-nonachlor (67.7%), gamma-chlordane (66.2%), chlorpyrifos (54.9%), cypermethrin (49.6%), and trans-permethrin (39.1%). More of those children in urban, non-farmworker families had detections of organochlorines (93.3% vs. 79.5, p = 0.0228) and pyrethroids (75.0% vs. 57.5%, p = 0.0351) than did those in rural, farmworker families; more children in rural, farmworker families had detections for organophosphates (71.2% vs. 45.0%, p= 0.0022). Children in urban, non-farmworker families had greater concentrations of alpha-chlordane (geometric mean (GM) 18.98, 95% CI 14.14, 25.47 vs. 10.25, 95% CI 7.49, 14.03; p= 0.0055) and dieldrin (GM 17.38, 95% CI 12.78 23.62 vs. 8.10, 95% CI 5.47, 12.00; p= 0.0034) than did children in rural, farmworker families. These results support the position that pesticides are ubiquitous in the living environment for children in vulnerable, immigrant communities, and argue for greater effort in documenting the widespread nature of pesticide exposure among children, with greater effort to reduce pesticide exposure.

Environmental Health Threats to Latino Migrant Farmworkers

Approximately 75% of farmworkers in the United States are Latino migrants, and about 50% of hired farmworkers do not have authorization to work in the United States. Farmworkers face numerous chemical, physical, and biological threats to their health. The adverse effects of these hazards may be amplified among Latino migrant farmworkers, who are concurrently exposed to various psychosocial stressors. Factors such as documentation status, potential lack of authorization to work in the United States, and language and cultural barriers may also prevent Latino migrants from accessing federal aid, legal assistance, and health programs. These environmental, occupational, and social hazards may further exacerbate existing health disparities among US Latinos. This population is also likely to be disproportionately impacted by emerging threats, including climate change and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Latino migrant farmworkers are essential to agriculture in the United States, and actions are needed to protect this vulnerable population.

A Comparison of Weight-Related Behaviors of Hispanic Mothers and Children by Acculturation Level

Hispanic mothers and children in the United States experience a high prevalence of obesity, which may be affected by maternal acculturation level. Little is known about the association of acculturation on weight-related behaviors. This study describes differences in weight-related behaviors by acculturation level of Hispanic mothers residing in the U.S. and compares them to behaviors of White mothers. Acculturation level was determined using personal acculturation and acculturation environment variables. Cluster analysis of acculturation variables identified three groups of Hispanic mothers: low personal and environmental acculturation (n = 46), high personal and low environmental acculturation (n = 65), and high personal and environmental acculturation (n = 38). Results indicate that, compared to White mothers (n = 340), the least acculturated cluster of Hispanic mothers tended to model physical activity less often and the most acculturated exerted more pressure on children to eat. Mothers in the least acculturated cluster tended to rate children’s health status lower, indicate that children had greater fruit juice and less milk intakes, have more meals in locations associated with less healthy meals, and have the least space and supports for physical activity. Findings highlight relationships between maternal acculturation level and weight-related behaviors and suggest strategies for helping acculturating Hispanic mothers create healthier lifestyles and home environments.

Stability of Household and Housing Characteristics Among Farmworker Families in North Carolina: Implications for Health

Household and housing stability are important for health and well-being of individuals, particularly children. This analysis examines stability in household and housing over 2 years for North Carolina farmworker families with children. Mothers with a child aged 2-4 years in farmworker families (n = 248) completed interviews over 2 years. Household measures included number of adults and children, moves, and spouse absence. Housing measures included tenure, persons per bedroom, and kitchen facilities. Household and housing characteristics for participants retained in the study over 2 years (n = 221) were stable in number of persons, tenure, persons per bedroom, and kitchen facilities. Households were large with one-third having 3 or more adults, and one-quarter having 4 or more children. Most families rented houses (over 15 % owned), which were crowded. Participants lost to follow-up were similar to retained participants in household characteristics, but had worse housing characteristics. Comparative research on farmworker family household composition is needed.

Residential Environment for Outdoor Play Among Children in Latino Farmworker Families

Child health and development benefit from physical activity. This analysis describes the residential play environment for children aged 2-4 years in farmworker families, their parent-reported levels of play and media time, and the association of residential environment with play and media time. Mothers with a child aged 2-4 years in farmworker families (n = 248) completed interviews over 2 years. Outcome measures were daily outdoor play time and media time. Measures of the residential environment included physical and social components. The mean min/day for outdoor play was 81.8 (SD 57.3) at baseline, 111.4 (SD 90.1) at year 1 follow-up, and 103.6 (SD 76.2) at year 2 follow-up. The mean media min/day at baseline was 83.8 (SD 64.3), 93.7 (SD 80.3) min/day at year 1 follow-up, and 59.9 min/day (SD (45.6) at year 2 follow-up. One additional person per bedroom was associated with 6 fewer min/day with media. The addition of each age appropriate toy was associated with an additional 12.3 min/day of outdoor play. An additional type of inappropriate media was associated with 6.8 more min/day with media. These results suggest changes to the residential environment to improve physical activity among children in Latino farmworker families.

Anticipatory Guidance about Child Diet and Physical Activity for Latino Farmworker Mothers

BACKGROUND

This analysis describes farmworker child health care utilization, anticipatory guidance for child weight, and the association of anticipatory guidance with personal characteristics, practice characteristics, and child's health care utilization.

METHODS

Data are from interviews conducted with 221 North Carolina Latino farmworker mothers with a child aged 4-5 years.

RESULTS

Half of the children were healthy weight, 19.0% were overweight, and 28.5% were obese. Most (56.4%) had been with the usual practice for two years or longer; most had well-child visits less frequently than once per year (71.5%). Fewer children with well-child visits than without were obese (14.8% vs. 35.5%; p=.01). More children with obesity than with healthy weight or overweight received guidance messages; more children without a well-child care visit in the past 12 months received guidance messages.

CONCLUSIONS

Health care providers are addressing anticipatory guidance when the opportunity arises. Creative approaches to address disparate primary care for farmworker families are important.

Collecting Comparative Data on Farmworker Housing and Health: Recommendations for Collecting Housing and Health Data Across Places and Time

The substandard nature of the housing in which most farmworkers live has detrimental effects on their health, as well as on their children's health and development. However, little research has directly documented associations between farmworker housing and health; existing research is not always comparable due to differences in design and measurement. Comparative data can help determine actual causal links between housing characteristics and farmworker health and help to evaluate the efficacy of current housing policy. The goal of this paper is to provide guidelines promoting comparable research on farmworker housing and the association of this housing with health. This paper reviews general concepts relevant to measuring farmworker housing and health, issues that should be considered in designing farmworker housing and health research, data collection methods, and measures. It concludes with recommendations for a research agenda on farmworker housing and health.
