This article looks into colonias, two or three generation homes in the United States where Mexican Americans live, specifically in Texas starting in the 1960s to present. Topics include the extent of official recognition of colonias with a focus on Pharr and McAllen, the impact of floods, and how the colonias' residents have organized themselves into communities to work together for inclusion.

This article engages with the consequences of overlapping environmental (in)justice, economic precarity, and informality as it relates to postflood survival in the colonias of Texas' Rio Grande Valley. Based on focus groups and interviews, this research reveals the slow and incremental character of adaption by historically disenfranchised communities. This "poco a poco"—or "bit by bit"—adaptive process reflects three main dimensions: the impacts of predatory lending and debt, the prioritization of immediate needs and its long-term consequences, and the precarity of slow postdisaster recuperation. The enduring precarity experienced by colonia residents results from a multifaceted marginalization including environmental racism, economic exclusion, and structural inequities ranging in scale from regional to familial. The concept of poco a poco postflood survival offers a nuanced understanding of responses to environmental vulnerability by marginalized groups and demonstrates the importance of small, microlevel processes enabling postdisaster survival.

This study examines literacies practiced in bilingual households located in emerging communities along the Texas-Mexico border known as border colonias. Drawing on theoretical notions of space as geographic and temporal, the simultaneity of global and local forces at work in colonias, and expressions of agency that are "in between" accommodation and resistance, we focus on the forms and practices of literacy that bilingual families are engaging in to satisfy financial and religious needs in Spanish and English. Through interviews and home visits with parents in two colonias, this qualitative study found diverse and interesting uses of written Spanish that can support children's biliteracy development even as the use of written Spanish is discouraged in schools and parents are ambivalent about the use of Spanish literacy for academic purposes. We identify four themes--what children learn through Spanish; child language socialization; biliteracy and human capital; and demographic and economic change--and identify possibilities for learning and research among this understudied population.

Context: Little is known about substance use and treatment utilization in rural communities of the United States/Mexico border. Purpose: To compare substance use and need and desire for treatment in rural colonias and urban areas of the border. Methods: Interviews were conducted in 2002-2003 with a random sample of adults living in the lower Rio Grande Valley of Texas, adjacent to the Mexican border. The present analysis compares responses from 400 residents of rural colonias to those of 395 residents of cities and towns in the same geographic region. Findings: While the prevalence of drug use and drug-related problems was similar in both areas, binge drinking and alcohol dependence were higher in rural colonias than in urban areas and remained so after taking demographic and neighborhood variables into account. An increase in illicit drug use and substance-related problems in rural but not urban areas was seen when comparing results from this study with those of a previous survey conducted in 1996. The percentage of adults in potential need of treatment and the percentage motivated to seek it were similar in both urban and rural areas. However, colonia residents were more likely than their urban counterparts to be recent immigrants and to have lower incomes and educational attainment, factors that can increase the barriers they face in getting needed services. Conclusions: Rural areas are "catching up" with urban areas in problematic substance use. Given the potential barriers to accessing treatment services in rural areas, efforts should be focused on reaching those residents.

This study describes the prevalence of alcohol and drug use, abuse, and dependence among adults on the Texas-Mexico border in 2002-2003. The findings are based on survey responses from a random sample of 1,200 adults living in households in three communities: El Paso, a densely populated city in west Texas; the less dense urbanized areas of the lower Rio Grande Valley in south Texas; and rural or semirural colonias--unregulated settlements characterized by lack of basic public services--in south Texas. The findings revealed similarity in drug use across the three sites but higher rates of binge drinking and alcohol dependence in the colonias. Border alcohol and drug use appeared similar or lower than use among residents of Texas as a whole or Hispanics nationwide; however, problems of abuse and dependence appeared somewhat higher on the border.

Critical to resolving the problem of health disparities among Latinos is examining the needs within ethnic subpopulations. This paper focused on the unique challenges encountered by one ethnic subpopulation -- Latinos of Mexican descent living in colonias. Findings reaffirm the importance of looking within ethnic subpopulations to understand the complexities of health disparities. This paper reports on data collected measuring access to health care among Latinos of Mexican descent living in several colonias in two southern Texas counties. Observations are based on data gathered from a nonprobability sample obtained through a face to face questionnaire focusing on health care access. Persons living in two Texas counties near the US border were included in this sample, and demographic data were compared to county, state and national statistics to examine the comparability of the sample to similar populations. Findings from this snowball sample, N=271, suggested lower rates of health insurance coverage compared to the Latino population nationwide, decreased patterns of preventive screenings for blood pressure, diabetes, cholesterol, cancers (ie, breast, cervical, and prostate), and regular access to health care in Mexico by slightly more than half the sample. Seeking care in Mexico may be a viable solution for many indigent people of Mexican descent living in close geographic proximity to the border because it surmounts the political, cultural, linguistic, or economic barriers to health care services in the United States. Nonetheless, there are longer term questions regarding quality of care and health and wellness for this group of people.

Purpose: This study describes the perceptions of brain health among older Spanish-speaking Mexican Americans who reside in colonia areas of the Lower Rio Grande Valley of Texas. Design and Methods: In 2007, 33 Mexican American older adults (9 men and 24 women) were recruited by "promotoras" (community health workers) from clusters of "colonias" in Hidalgo County to participate in focus group discussions conducted in Spanish. After participants completed a 19-item questionnaire (in Spanish), a bilingual and bicultural researcher from the community, trained as a moderator, conducted 4 focus groups using a semistructured interview guide, culturally modified with the assistance of "promotoras". All discussions were audio recorded; audio recordings were transcribed verbatim in Spanish and then translated into English. Analyses were conducted in English. Results: Almost 85% had less than a high school education and 100% reported a household income less than $20,000/year. Groups attached cultural meaning to aging well. The idea of "staying straight in the mind" resonated as a depiction of brain health. Participants also mentioned the types of activities they could do to stay "right in the mind." Implications: Particular attention must be focused on development of programs that provide satisfying culturally appropriate activities for older participants and the delivery of health messages that take into consideration culture and language.

U.S. border colonias are peri-urban settlements along the U.S.-Mexico border. Residents often face substandard housing, inadequate septic and sewer systems, and unsafe or inadequate household water. As of 2015, an estimated 30% of over 5 million U.S. colonia residents lacked access to clean drinking water, suggesting health complications. This scoping review identifies a very limited existing set of research on water and sanitation insecurity in U.S.-Mexico border colonias, and suggests value in additional focused research in this specific context to address health challenges. Preliminary health data indicates that due to water insecurity, colonia residents are more likely to contract gastrointestinal diseases, be exposed to carcinogenic compounds from contaminated water, and experience psychosocial distress. These widespread health issues in colonias are exacerbated by historical and ongoing socioenvironmental injustices in the U.S.-Mexico border region and their relation to the poor health outcomes.

Mosquitoes and the diseases they transmit continue to place millions of people at risk of infection around the world. Novel methods of vector control are being developed to provide public health officials with the necessary tools to prevent disease transmission and reduce local mosquito populations. However, these methods will require public acceptance for a sustainable approach and evaluations at local settings. We present our efforts in community engagement carried out in colonias of the Lower Rio Grande Valley in south Texas for mosquito surveillance, control, and ecological projects. Along the US-Mexico border the term colonia refers to impoverished communities that are usually inhabited by families of Hispanic heritage. The different engagements were carried out from September 2016 to February 2019; during this time, we had three distinct phases for community engagement. In Phase 1 we show the initial approach to the colonias in which we assessed security and willingness to participate; in Phase 2 we carried out the first recruitment procedure involving community meetings and house-to-house recruitment; and in Phase 3 we conducted a modified recruitment procedure based on community members' input. Our findings show that incorporating community members in the development of communication materials and following their suggestions for engagement allowed us to generate culturally sensitive recruitment materials and to better understand the social relationships and power dynamics within these communities. We were able to effectively reach a larger portion of the community and decrease the dropout rate of participants. Progress gained with building trust in the communities allowed us to convey participant risks and benefits of collaborating with our research projects. Community engagement should be viewed as a key component of any local vector control program as well as for any scientific research project related to vector control. Even in the face of budgetary constraints, small efforts in community engagement go a long way., (© 2022. The Author(s).)

Physical activity (PA) is beneficial for child health; however, few children meet PA guidelines. Social relationships impact child PA behaviors; however, little is known about this effect in Mexican-heritage populations. This study aims to understand associations between self-reported play networks and PA among Mexican-heritage children. Mexican-heritage children from colonias along the Texas-Mexico border (n = 44; 54.5% girls; mean age = 9.89 years, SD = 0.97) reported information on up to 5 people they played with most often. Linear regression was used to analyze the relationship between composition of children's social network and minutes of moderate- to vigorous-intensity PA (MVPA) and sedentary minutes per day measured by accelerometers. Children who reported a higher percentage of friends as opposed to family members attained significantly more minutes of MVPA per day (β = .27, P = .04). Children who reported playing with individuals in their network more often (β = ‒.28, P = .03) were sedentary for fewer minutes per day. Increasing the connections between children in the neighborhood or community, as well as increasing a child's frequency of active play, may be promising approaches to increasing MVPA and decreasing sedentary behaviors among Mexican-heritage children., Competing Interests: The authors have no conflicts of interest to report., (Copyright © 2021 Wolters Kluwer Health, Inc.

This study examined differences in mother-reported physical activity (PA) and screen time (ST) based on child sex and mothers' perceptions of PA resources for Mexican-heritage (MH) children residing in Texas-Mexico border colonia s. Mothers with children 8 to 10 years old (n = 335) from colonias in south Texas reported if there were places for their child to be physically active and their child's hours of PA and ST per day during the week and weekend. Two-way ANCOVAs examined differences in child PA and ST based on presence of PA places and child sex. Only 46.0% of mothers (n = 159) reported places for their child to be physically active; with no significant difference based on sex. Mothers' perceptions of a place to play was differentially beneficial for girls' weekday PA and ST. Findings suggest a need to increase perceived and/or actual access to PA places in colonias communities, particularly for girls. [ABSTRACT FROM AUTHOR]

Several Texas communities along the Mexican border, including the Lower Rio Grande Valley (LRGV), are home to low-income Hispanic populations, many of whom live in underserved communities known as colonias. These areas have high incidences of neurocognitive disorders, dementia, and Alzheimer's disease (AD); health care strategies that are culturally and linguistically appropriate for the area are needed. We aim to build capacity to reduce risk, facilitate treatment, and provide caregiver support for affected individuals. However, gaining trust of communities and presenting information about research studies in a way that is culturally appropriate is critical for engagement of underserved communities. This brief report examines our work with local community health workers.(CHWs), promotores in Spanish, to establish contact with, engage, mobilize, and educate the Hispanic communities of the LGRV. Lessons from the succesful experience of training promotores in autism spectrum disorder in the LRGV highlight the importance of specifically addressing outreach in health fairs, clinic vists and referral as well as adequate selection, training, management, and support of the promotores as critical aspects. To initiate and sustain recruitment of older adults and care partners in research studies of AD and other dementias in the RGV, we have incorporated these aspects as components of the promotores training and engagement model, which has been developed and implemented by researchers and their colleagues at the School of Medicine at the University of Texas Rio Grande Valley., Competing Interests: Competing Interests: None declared., (Copyright © 2020, Ethnicity & Disease, Inc.)

Despite growing health disparities in Latino populations related to lack of physical activity (PA), little is known regarding the impact of social networks on PA and sedentary behavior among a sample of Latino fathers residing in functionally rural colonias . Fathers wore accelerometers and responded to questions regarding their self-efficacy and characteristics of who they were active with most often. Fathers ( n = 47) attained a mean of 73.3 min of moderate-to-vigorous PA (SD = 23.8) per day and were sedentary for a mean of 364.0 min (SD = 74.4) per day. In total, fathers reported 205 alters and significantly more family members (M = 3.60, SD = 1.64) than friends (M = 0.77, SD = 1.37). Sedentary time was positively associated with number of peers and inversely related to the number of children reported. Minutes of moderate-to-vigorous PA was significantly associated with greater self-efficacy and number of family members reported. This study contributes to the evidence by further examining PA correlates of Latino fathers from functionally rural colonia communities. Additionally, this study supported both family systems theory and the socio-ecological model as it details the interpersonal and familial influences of PA behavior. Thus, supports for family activity promotion and programs which impact familial norms and activity at the family level may be particularly useful.

Many of the six million residents of unincorporated communities in the United States depend on well-water to meet their needs. One group of unincorporated communities is the colonias, located primarily in several southwestern U.S. states. Texas is home to the largest number of these self-built communities, of mostly low-income families, lacking basic infrastructure. While some states have regulations that mandate minimum infrastructure for these communities, water and sewage systems are still lacking for many of their residents. Unprotected wells and self-built septic/cesspool systems serve as the primary infrastructure for many such colonias. This research was designed to probe how wells and septic/cesspool systems are influenced by heavy rainfall events. Such events are hypothesized to impact water quality with regard to human health. Inorganic and microbiological water quality of the wells in nine colonias located in Nueces County, Texas, were evaluated during dry and wet periods. Nueces County was selected as an example based on its flooding history and the fact that many colonias there depend entirely on well-water and septic/cesspool systems. The results demonstrate that well-water quality in these communities varies seasonally with respect to arsenic (up to 35 μg/L) and bacterial contamination (Escherichia coli), dependent on the amount of rainfall, which leaves this population vulnerable to health risks during both wet and dry periods. Microbial community analyses were also conducted on selected samples. To explore similar seasonal contamination of well-water, an analysis of unincorporated communities, flooding frequency, and arsenic contamination in wells was conducted by county throughout the United States. This nationwide analysis indicates that unincorporated communities elsewhere in the United States are likely experiencing comparable challenges for potable water access because of a confluence of socioeconomic, infrastructural, and policy realities., Competing Interests: Declaration of competing interest The authors certify that they have no affiliations with or involvement in any organization or entity with any financial interest (such as honoraria; educational grants; participation in speakers' bureaus; membership, employment, consultancies, stock ownership, or other equity interest; and expert testimony or patent-licensing arrangements), or non-financial interest (such as personal or professional relationships, affiliations, knowledge or beliefs) in the subject matter or materials discussed in this manuscript., (Copyright © 2020 Elsevier B.V.

Breast cancer is the second leading cause of cancer death among women of all ethnicities. Though the disease is not a primary concern within male populations male perceptions and beliefs of breast cancer screening may contribute to a partner's or loved one's decision to engage in regular mammograms or clinical breast examinations. The current study seeks to explore a comparative analysis of breast cancer knowledge, beliefs, susceptibility, and barriers to female breast cancer and breast cancer screening among Hispanic men and women residing in the Colonias of South Texas. Using a multistage systematic sampling design, 2,812 men and women were surveyed from the two South Texas Counties; Maverick and Val Verde. Individuals between the ages of 20 and 75 (n = 2360) were included in the analysis. T-tests and linear regression models were used to examine gender differences in, knowledge, beliefs, susceptibility, and barriers to breast cancer and breast cancer screening. Significant differences were found between males and females across all measures. Regression analysis demonstrates Hispanic women hold more favorable beliefs about breast cancer and early detection, display higher perceived barriers to clinical breast examinations and mammography, and view themselves more susceptible to the development of breast cancer than their male counterparts. Results framed within a cultural context suggest outreach efforts within South Texas Colonias should consider inclusion of male family members in efforts to increase favorable views toward and engagement in regular breast cancer screening.

Community asset mapping ( CAM) is the collective process of identifying local assets and strategizing processes to address public health issues and concerns and improve quality of life. Prior to implementing a community-based physical activity intervention with Latinas in the Texas Lower Rio Grande Valley, promotoras [community health workers] conducted 16 interactive sessions in 8 colonias. The analysis of the transcribed CAM recordings and on-site observational data resulted in the construction of Living in Limbo as the thematic representation of these Latinas' social isolation and marginalization associated with pervasive poverty, undocumented immigration status or lack of citizenship, their fears emanating from threats to physical and emotional safety, and the barriers created by lack of availability and access to resources.

In this article, we compare colonias in Texas and California and evaluate the federal policy relating to them. In Texas, designated colonias are recently subdivided but unregulated housing settlements that lack infrastructure. California's designated colonias are old communities, with varying demographics, infrastructure needs, and jurisdictional authority. Because subdivisions are strongly regulated in California, we did not expect to find designated colonias there. In actuality, there are over 30. However, federal policy is based on Texas colonias, and we argue that it is too broad because it fails to distinguish between inherently distinct areas and investment needs. Paradoxically, the federal criteria for defining colonias are also too narrow. Many locally designated colonias in California do not qualify for funding because they are not close to the Mexican border or exceed the population ceiling. Ironically, some of the colonias that fail to qualify have the worst housing conditions. [ABSTRACT FROM AUTHOR]

Colonias, which are unincorporated border settlements in the United States, have emerged in rural areas without the governance and services normally provided by local government. Colonia residents live in poverty and lack adequate health care, potable water, and sanitation systems. These conditions create substantial health risks for themselves and surrounding communities. By 2001, more than 1,400 colonias were identified in Texas. Cooperation with several Federal and Texas state agencies has allowed the U.S. Geological Survey (USGS) to improve colonia Geographic Information System (GIS) boundaries and develop the Colonia Health, Infrastructure, and Platting Status tool (CHIPS). Together, the GIS boundaries and CHIPS aid the Texas government in prioritizing the limited funds that are available for infrastructure improvement. CHIPS's report generator can be tailored to the needs of the user, providing either broad or specific output. CHIPS is publicly available on the U.S. Geological Survey Border Environmental Health Initiative website at http://borderhealth.cr.usgs.gov. [ABSTRACT FROM AUTHOR]

Municipal underbounding is the systematic failure of cities to annex surrounding minority communities. Recent analyses of the phenomenon in the United States have focused on small White Southern towns with African American communities along the jurisdictional fringe. This paper applies similar logic to the study of the exclusion of colonias in the Lower Rio Grande Valley (LRGV) of Texas. These low-income informal settlements, located in the hinterlands of cities, have historically had high rates of poverty, poor housing quality, and insufficient infrastructure and utility service. Using TIGER/ Line files (GIS shapefiles), Summary Files of the U S decennial censuses, and ArcGIS technology this project explores the prevalence of the municipal underbounding of colonias. In order to place the issue of municipal annexation in context, the paper begins with a description of regional demographic and socioeconomic characteristics, municipal growth, and annexation patterns in the LRGV. The paper then explores the extent to which colonias have been selectively excluded from annexation using logistic and autologistic regression. The results suggest that census blocks that contain colonias are less likely to be annexed than are other census blocks; in addition, those census blocks that contain colonias with poor infrastructure appear to have odds of being annexed that are lower still. The paper concludes with a discussion of the policy implications of these findings. [ABSTRACT FROM AUTHOR]

Abstract: Owner-occupied housing is the norm in the low-income, informal settlements along the US–Mexico border known as colonias. As a result, renters and renting have been largely overlooked by both scholars and policymakers. Using GIS technology and data provided by the US Census Bureau from 2000 to 2011, this article is the first to 1) document the growth of renting in these settlements in recent years and the nature and extent of the rental market, and 2) explore important differences between owner and renter households and the myriad ways in which colonia renters are more vulnerable than homeowners. The results suggest that renting in colonias is largely informal and occurs primarily in single-unit homes, many of which were built via self-help by the owner and have since been converted to rental property. As a result of these findings, it is argued that renting in colonias more closely resembles the rental market in informal settlements throughout the developing world than it does the rental market elsewhere in Texas, and thus the rise of renting in colonias presents unique challenges that merit attention by both scholars and policymakers. The article concludes by drawing upon insights from research on renting in the developing world in order to highlight key policy priorities regarding renting in colonias. [Copyright &y& Elsevier]

Along the Texas border with Mexico, more than 400,000 people live in over 2,000 informal self-help settlements known ascolonias. These exceedingly low-income, largely Latino settlements have historically suffered from severe health risks, poor infrastructure and housing conditions, and physical and social isolation. Researchers and policymakers have focused extensively on what I call “first-generation policy priorities.” This has primarily entailed efforts to regularize title and infrastructure, support self-help home improvement forcoloniahomeowners, and prevent the growth of new informal settlements along the border region. I provide a comprehensive review of existing research oncoloniasto document the myriad ways in which housing and infrastructure conditions and titling practices have changed since these settlements first proliferated throughout the border region in the second half of the 20th century. These changes necessitate a rethinking of the policy priorities forcoloniasand informal settlements throughout the state. In particular, I argue thatcoloniasmust be recast to recognize the significant improvements that have taken place but also the long-term and sometimes severe problems that persist. These “second-generation policy priorities” include the development of sustainable forms of governance, regulation, and finance to address ongoing infrastructure investment needs incolonias; supporting access to and upkeep of safe and affordable renter- and owner-occupied housing through both self-help and contractor-led projects; ensuring long-term title clarity; and promoting community organizing in new and aging settlements.

This study examines breast cancer knowledge, attitudes and screening behaviors of Hispanic women living in the South Texas colonias of Maverick and Val Verde Counties. We used the Health Belief Model to analyze the effects of HBM constructs on clinical breast exam (CBE) and mammogram screening. Using a multistage systematic sampling approach we interviewed women living within these colonias. Logistic regression analysis was used to predict CBE and mammography screening behaviors. The results indicate that knowledge, susceptibility, barriers and source of health information were statistically significant in predicting CBE among these women. In addition, background variables such as marital status and health insurance were also significant in predicting CBE. Findings further indicate that source of health information, barriers, and health insurance significantly predicts mammography screening behaviors. Results suggest that for women living in colonias along the South Texas Border socio-demographic variables play a significant role in CBE and mammography utilization. [ABSTRACT FROM AUTHOR]

Objective: An innovative academic‐community partnership studied daily decisions in communities of mostly Spanish‐speaking, low‐income residents of colonias in Hidalgo County, TX, about risk of exposure to fish contaminated by PCBs at an Environmental Protection Agency (EPA) Superfund site. Design and Sample: The team used focus group interviews with colonia residents and content analysis to assess knowledge of risk related to the Superfund site, the Donna Reservoir and Canal System. Results: (1) many lacked knowledge of the Superfund site contamination; (2) a few participants fished at the lake, knew people who did so, and consumed the catch, but most participants feared going there; (3) some participants remember receiving messages saying not to fish at the site, although they recalled nothing about contamination, but most participants knew of no such messages; (4) many use cell phones to get local information through personal networks and several Spanish‐language news sources, but they have no consistent, culturally tailored local information source. Conclusions: The findings indicate the need for further efforts to design culturally tailored means of communication and messages to inform local communities widely about the dangers related to the Superfund site and thus decrease health disparities resulting from consuming fish from the site.

• A law introduced in 1995 created a logical dependency between critical infrastructure services—namely, water, wastewater, and energy— in attempt to improve conditions in colonias. • This statewide policy impacted communities differently, as demonstrated with varying parameter associated across counties and expressed anecdotally by promotoras and decision-makers. • In general, the law is perceived by promotoras and decision-makers to have improved the living conditions in colonias, but much more can be done at a local level. • The lack of patterns among associated parameters across counties suggests that each county has been affected differently by implemented policy. • There is a need for a uniformly recognized definition for colonias - and in general, urban slums - that include energy/electricity. A subset of peri-urban and urban subdivisions, known as colonias, often lack access to infrastructure services. One way to improve services in these communities is through policy and laws, such as one enacted in Texas in 1995. This particular law aims to encourage in-place upgrading of infrastructure in colonias by using as leverage the residents' prioritization of energy service in households above other services. This law imposed a logical dependency; it required residents—prior to connecting to energy services—to first register their platted land and then connect to water and wastewater services. Now two decades later, this study assesses what built-environment parameters are associated with water and wastewater access, and which thereby impact energy access. The study also assesses the perceived burden and efficacy of this law on border colonia residents. Helped by publicly available data and semi-structured interviews, this work explores infrastructure services using hypothesis testing and qualitative methods. In this analysis, we look at three Texas counties——and the 1297 colonias contained therein. Findings from this study suggest decision makers should focus not just on those policies and laws in place but also on localized, tailored county/city-level efforts to increase access.

Both the planning and public health literature have discussed proximity to greenspaces as predominantly beneficial to health, based on studies mostly conducted in high-income regions. Understanding the health risks of proximity to greenspace and nature—where pathogens and wildlife coexist—is important, as nature-based solutions are increasingly called for to address complex urban challenges. This exploratory pilot study bridges planning and epidemiology approaches to develop a new method to analyze habitat and environmental factors associated with the risk of vector-borne Chagas disease in a low-income region, South Texas. Chagas disease is endemic in Latin America, where it affects between seven to eight million people and where environmental factors have been studied to limit the disease's spread. The disease is considered endemic in the southern United States, where little is known about environmental risks. In this pilot study, we developed a new methodology to analyze publicly available habitat and environmental secondary data, which could be used by planning departments. We applied the method to a prior pilot study, which determined a 19.6% prevalence level of T. cruzi (the agent of Chagas disease) among 209 domestic dogs. We geocoded the sample to 100 low-income residential locations, which yielded a 32% positivity rate, and collected secondary data surrounding each location. Logistical regression of factors yielded the following risks: adjacent unconstructed lots, and the presence of four or more dogs in a yard. Based on the results, we formulated vector control-based planning policy recommendations to prevent the spread of the disease. [Display omitted] [ABSTRACT FROM AUTHOR]

Our study investigates why low-income Mexican-American residents living in rural and periurban subdivisions (colonias) in South Texas, one of the poorest regions in the United States, are increasingly dependent upon water vending machines as the main source of drinking water despite continued water infrastructure development. We outline a relational framework that builds on current debates within nature-society scholarship to address this paradox. We demonstrate how institutional enclosure--the creation or repurposing of institutions that curtails public participation in water governance--paired with water quality discourses and daily practices, operate over time to enroll residents as neoliberal subjects. We focus our attention on the emergence of the 'water consumer', or the individual who purchases drinking water from the vending machine. This approach addresses the coproduction of political subjectivities in relation to institutional change and how subjectivity reconstitutes a new hydrosocial relationship mediated by the water vending machine. We argue for a relational approach that attends to the production of political subjectivities as central to, not as a result of, the neoliberalization of nature. [ABSTRACT FROM AUTHOR]

Background: Food insecurity is associated with detrimental physical, psychological, behavioral, social, and educational functioning in children and adults. Greater than one-quarter of all Hispanic households in the U.S. are food insecure. Hispanic families in the U.S. comprise 30% of households with food insecurity at the child level, the most severe form of the condition. Methods: Food security discordance was evaluated among 50 Mexican-origin children ages 6-11 and their mothers living in Texas border colonias from March to June 2010. Mothers and children were interviewed separately using promotora-researcher administered Spanish versions of the Household Food Security Survey Module and the Food Security Survey Module for Youth. Cohen's kappa statistic (?) was used to analyze dyadic agreement of food security constructs and level of food security. Results: Eighty percent of mothers reported household food insecurity while 64% of children identified food insecurity at the child level. There was slight inter-rater agreement in food security status (? = 0.13, p = 0.15). Poor agreement was observed on the child hunger construct (? = -0.06, p = 0.66) with fair agreement in children not eating for a full day (? = 0.26, p < 0.01) and relying on low-cost foods (? = 0.23, p = 0.05). Conclusions: Mother and child-reported household and child-level food insecurity among this sample of limited-resource Mexican-origin colonias residents far surpass national estimates. While the level of dyadic agreement was poor, discordance may be attributable to parental buffering, social desirability in responses, and/or the age of children included in the present analysis. Future research should continue to explore how food security is understood from the perspectives and experiences of children and adolescents. [ABSTRACT FROM AUTHOR]

Abstract: There is a paucity of studies acknowledging the existence of alternative food sources, and factors associated with food purchasing from three common alternative sources: vendedores (mobile food vendors), pulgas (flea markets), and vecinos/amigos (neighbors/friends). This analysis aims to examine the use of alternative food sources by Mexican-origin women from Texas-border colonias and determine factors associated with their use. The design was cross-sectional. Promotora-researchers (promotoras de salud trained in research methods) recruited 610 Mexican-origin women from 44 colonias and conducted in-person surveys. Surveys included participant characteristics and measures of food environment use and household food security. Statistical analyses included separate logistic regressions, modeled for food purchase from mobile food vendors, pulgas, or neighbors/friends. Child food insecurity was associated with purchasing food from mobile food vendors, while household food security was associated with using pulgas or neighbors/friends. School nutrition program participants were more likely to live in households that depend on alternative food sources. Efforts to increase healthful food consumption such as fruits and vegetables should acknowledge all potential food sources (traditional, convenience, nontraditional, and alternative), especially those preferred by colonia residents. Current findings support the conceptual broadening of the retail food environment, and the importance of linking use with spatial access (proximity) to more accurately depict access to food sources.

This article examines the idea of empowerment through food preparation and applies it to a specific context—that of the life of immigrant Mexican women from two South Texas settlement areas, or colonias. Based on ethnographic data gathered through participant observation by bilingual research teams of promotoras and formally educated health professionals embedded with participant families, we analyze the living situations of low-income Mexican women in the South Texas colonias, particularly their food procurement, storage, and preparation practices for their families. We acknowledge the existence of hegemonic gendered, economic, and racialized structures of domination that surround the women's role in food preparation. However, we also recognize food preparation as the domain in which otherwise oppressed and marginalized women, living a life of isolation filled with severe problems and uncertainties, exercise some degree of power and control within their lives and the well-being of their family members. Included are implications for further research on communal empowerment. [ABSTRACT FROM PUBLISHER]

Abstract: Accounts of the retail food environment have been limited by research that focused on supermarkets, grocery stores, and restaurants as the principal food sources for consumers. Little is known about alternative retail food sources, especially in rural and underserved areas such as the colonias along the South Texas border with Mexico. Many colonias are located near pulgas (flea markets). This is the first study to examine this alternative food source for colonia residents. This study''s purpose is to provide preliminary data on food availability in this unstudied element of the retail food environment. Five pulgas were identified for study by local informants. Two separate teams of two promotores (indigenous community health workers) conducted observations, wrote field notes, and surveyed vendors in each pulga. Traditional foods, prepared foods, and fresh fruits and vegetables were available in the observed pulgas. Traditional foods included staples, meal items, and snacks and sweets. Prepared foods were available in small stands run by independent operators, and each pulga had permanent restaurants that served prepared foods. A large variety of fresh fruits and vegetables were also available. An emphasis on supermarkets and grocery stores will provide an incomplete account of the retail food environment. Further studies should attempt to provide a more complete account by identifying alternative retail sources used by local residents. One such alternative retail food source, the pulga, provides a range of traditional food stuffs, prepared food items, and fruits and vegetables that complement conventionally studied aspects of the retail food environment.

Promotoras are trusted members of underserved, at-risk Hispanic communities experiencing social and health inequities. As promotora-researchers, promotoras have the unique ability and opportunity not only to provide outreach and education but also to be actively engaged in conducting research in their communities and serve as a cultural bridge between the community and researchers. In this article, we present a case study of personal and collective empowerment of six promotora-researchers who participated in seven community-based participatory research projects. Data sources included debriefing interviews with the promotora-researchers, milestone tracking and documentation completed during and after each study, and observations by the principal investigator and project managers regarding the role of the promotora-researchers in these studies. We qualitatively analyzed the data to identify the processes and decisions that were developed and implemented in a series of projects, which resulted in promotora-researcher empowerment. We found that active engagement empowered promotora-researchers personally and collectively in all phases of the research study. Common elements that contributed to the empowerment of promotora-researchers were valuing promotora-researchers' input, enabling promotora-researchers to acquire and utilize new skills, and allowing promotora-researchers to serve as both researchers and traditional promotoras. Together, these elements enabled them to more fully participate in research projects, while allowing them to identify and address needs within their own communities.

Experience in colonias--informal communities in Texas characterized by the absence of water and sewer systems-demonstrates that a well-funded programme to subsidize infrastructure can falter if the incentives and management capacity of involved organizations do not support effective implementation. The Texas Legislature established the Economic Distressed Areas Programme (EDAP) in 1989 to subsidize service providers constructing water and sewer systems in colonias. A longitudinal assessment of EDAP found that the programme performed poorly until the late 1990s when the institutional context of the agency administering the programme changed. These changes led to a more effective set of incentives to implement the programme and improved performance. General lessons regarding programme performance are derived from the research results.

The qualitative study described in this article investigated perceptions about environmental factors influencing physical activity (PA) among children from underserved neighborhoods known as colonias in the U.S.-Mexico border. Ten focus groups were conducted with 67 Mexican- American colonia children ages 8 to 13 living in one of the poorest border counties in the U.S. Analyses indicated that PA among children was influenced by neighborhood characteristics, including litter, speeding cars, unleashed dogs, and dark streets. The children also underlined intrapersonal and social environmental factors. Findings may inform policy makers and public health professionals about ways to promote PA among underserved children through urban planning and programs focusing on PA-supportive infrastructure, neighborhood safety, and family- and home-based physical activities.

Background: Few studies have focused on the relationship between the retail food environment and household food supplies. This study examines spatial access to retail food stores, food shopping habits, and nutrients available in household food supplies among 50 Mexican-origin families residing in Texas border colonias. Methods: The design was cross-sectional; data were collected in the home March to June 2010 by promotoraresearchers. Ground-truthed methods enumerated traditional (supercenters, supermarkets, grocery stores), convenience (convenience stores and food marts), and non-traditional (dollar stores, discount stores) retail food stores. Spatial access was computed using the network distance from each participant's residence to each food store. Data included survey data and two household food inventories (HFI) of the presence and amount of food items in the home. The Spanish language interviewer-administered survey included demographics, transportation access, food purchasing, food and nutrition assistance program participation, and the 18-item Core Food Security Module. Nutrition Data Systems for Research (NDS-R) was used to calculate HFI nutrients. Adult equivalent adjustment constants (AE), based on age and gender calorie needs, were calculated based on the age- and gender composition of each household and used to adjust HFI nutrients for household composition. Data were analyzed using bivariate analysis and linear regression models to determine the association of independent variables with the availability of each AE-adjusted nutrient. Results: Regression models showed that households in which the child independently purchased food from a convenience store at least once a week had foods and beverages with increased amounts of total energy, total fat, and saturated fat. A greater distance to the nearest convenience store was associated with reduced amounts of total energy, vitamin D, total sugar, added sugar, total fat, and saturated fat. Participation in the National School Lunch Program (NSLP) was associated with lower household levels of total energy, calcium, vitamin C, sodium, vitamin D, and saturated fat. Spatial access and utilization of supermarkets and dollar stores were not associated with nutrient availability. Conclusions: Although household members frequently purchased food items from supermarkets or dollar stores, it was spatial access to and frequent utilization of convenience food stores that influenced the amount of nutrients present in Texas border colonia households. These findings also suggest that households which participate in NSLP have reduced AE-adjusted nutrients available in the home. The next step will target changes within convenience stores to improve in-store marketing of foods and beverages to children and adults. [ABSTRACT FROM AUTHOR]

Abstract: Applying the concept of microlending to housing is gaining momentum as a practical alternative for those who are on the margin of mainstream financial services. Microlending has been widely researched in the context of developing countries, but less is known about how – and if – it works on marginalized groups in developed countries, specifically in relation to housing. Using the case of South Texas colonias, this paper explores a microlending program for home improvements and its capacity to impact the local economy. Basic data comes from the Nuestra Casa lending program database (609 clients) and from face to face interviews with a randomly selected sample of 138 clients. Our findings show that this program targets and serves clients from the unbanked population, who do not have access to other lending alternatives; further, 70% of the current clients are living below the poverty threshold; defaults rates are found to be low, indicating a capacity to pay loans based on income-to-debt instead of loan-to-debt ratios; and finally, it positively impacts the local economy, since labor and materials necessary to implement the improvements, are purchased locally. These findings should give us policy guidelines to evaluate lending programs that attached to local economies and are suited to serve the target populations. [ABSTRACT FROM AUTHOR]

Background: It has been recognized that the availability of foods in the home are important to nutritional health, and may influence the dietary behavior of children, adolescents, and adults. It is therefore important to understand food choices in the context of the household setting. Considering their importance, the measurement of household food resources becomes critical. Because most studies use a single point of data collection to determine the types of foods that are present in the home, which can miss the change in availability within a month and when resources are not available, the primary objective of this pilot study was to examine the feasibility and value of conducting weekly in-home assessments of household food resources over the course of one month among low-income Mexicano families in Texas colonias. Methods: We conducted five in-home household food inventories over a thirty-day period in a small convenience sample; determined the frequency that food items were present in the participating households; and compared a one-time measurement with multiple measurements. After the development and pre-testing of the 252-item culturally and linguistically-appropriate household food inventory instrument that used direct observation to determine the presence and amount of food and beverage items in the home (refrigerator, freezer, pantry, elsewhere), two trained promotoras recruited a convenience sample of 6 households; administered a baseline questionnaire (personal info, shopping habits, and food security); conducted 5 in-home assessments (7-day interval) over a 30-day period; and documented grocery shopping and other food-related activities within the previous week of each in-home assessment. All data were collected in Spanish. Descriptive statistics were calculated for mean and frequency of sample characteristics, food-related activities, food security, and the presence of individual food items. Due to the small sample size of the pilot data, the Friedman Test and Kendall's W were used to assess the consistency of household food supplies across multiple observations. Results: Complete data were collected from all 6 Mexicano women (33.2y ± 3.3; 6.5 ± 1.5 adults/children in household (HH); 5 HH received weekly income; and all were food insecure. All households purchased groceries within a week of at least four of the five assessments. The weekly presence and amounts of fresh and processed fruits and vegetables, dairy, meats, breads, cereals, beverages, and oils and fats varied. Further, the results revealed the inadequacy of a one-time measurement of household food resources, compared with multiple measures. The first household food inventory as a one-time measure would have mistakenly identified at least one-half of the participant households without fresh fruit, canned vegetables, dairy, protein foods, grains, chips, and sugarsweetened beverages. Conclusions: This study highlights the value of documenting weekly household food supplies, especially in households where income resources may be more volatile. Clearly, the data show that a single HFI may miss the changes in availability - presence and amount - that occur among low-income Mexicano households who face challenges that require frequent purchase of foods and beverages. Use of multiple household food inventories can inform the development and implementation of nutrition-related policies and culturally sensitive nutrition education programs. [ABSTRACT FROM AUTHOR]

Following the 1993 passage of the North American Free Trade Agreement (NAFTA), the Texas-Mexico border region has experienced rapid growth. Much of this growth has occurred in colonias which often lack proper sewage and water treatment systems. This manuscript reports on activities linking research with health promotion in these communities. Based on meetings that prioritized community concerns, a Safe Drinking Water module was developed and delivered to more than 200 families. Results from the testing demonstrated a significant improvement in correct answers. These data indicate that community health education can be an effective tool in improving health awareness.

Background: Nutritional health is essential for children's growth and development. Many Mexican-origin children who reside in limited-resource colonias along the Texas-Mexico border are at increased risk for poor nutrition as a result of household food insecurity. However, little is known about the prevalence of child hunger or its associated factors among children of Mexican immigrants. This study determines the prevalence of child hunger and identifies protective and risk factors associated with it in two Texas border areas., Methods: This study uses 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA) data from 470 mothers who were randomly recruited by promotora-researchers. Participants from colonias near two small towns in two South Texas counties participated in an in-home community and household assessment. Interviewer-administered surveys collected data in Spanish on sociodemographics, federal food assistance program participation, and food security status. Frequencies and bivariate correlations were examined while a random-effects logistic regression model with backward elimination was used to determine correlates of childhood hunger., Results: Hunger among children was reported in 51% (n = 239) of households in this C-HCFRA sample. Bivariate analyses revealed that hunger status was associated with select maternal characteristics, such as lower educational attainment and Mexican nativity, and household characteristics, including household composition, reliance on friend or neighbor for transportation, food purchase at dollar stores and from neighbors, and participation in school-based nutrition programs. A smaller percentage of households with child hunger participated in school-based nutrition programs (51%) or used alternative food sources, while 131 households were unable to give their child or children a balanced meal during the school year and 145 households during summer months. In the random effects model (RE = small town), increased household composition, full-time unemployment, and participation in the National School Lunch Program were significantly associated with increased odds for child hunger, while participation in Supplemental Nutrition Assistance Program (SNAP) and purchasing food from a neighbor were significantly associated with decreased odds for child hunger., Conclusions: This study not only emphasizes the alarming rates of child hunger among this sample of Mexican-origin families, but also identifies economic and family factors that increased the odds for child hunger as well as community strategies that reduced the odds. It is unsettling that so many children did not participate in school-based nutrition programs, and that many who participated in federal nutrition assistance programs remained hungry. This study underscores the importance of identifying the presence of child hunger among low-income Mexican-origin children in Texas border colonias and increasing access to nutrition-related resources. Hunger-associated health inequities at younger ages among colonia residents are likely to persist across the life span and into old age.

In 2011, an estimated 50.2 million adults and children lived in US households with food insecurity, a condition associated with adverse health effects across the life span. Relying solely on parent proxy may underreport the true prevalence of child food insecurity. The present study sought to understand mothers' and children's (aged 6-11 y) perspectives and experiences of child food insecurity and its seasonal volatility, including the effects of school-based and summertime nutrition programs. Forty-eight Mexican-origin mother-child dyads completed standardized, Spanish-language food-security instruments during 2 in-home visits between July 2010 and March 2011. Multilevel longitudinal logistic regression measured change in food security while accounting for correlation in repeated measurements by using a nested structure. Cohen's κ statistic assessed dyadic discordance in child food insecurity. School-based nutrition programs reduced the odds of child food insecurity by 74% [OR = 0.26 (P < 0.01)], showcasing the programs' impact on the condition. Single head of household was associated with increased odds of child food insecurity [OR = 4.63 (P = 0.03)]. Fair dyadic agreement of child food insecurity was observed [κ = 0.21 (P = 0.02)]. Obtaining accurate prevalence rates and understanding differences of intrahousehold food insecurity necessitate measurement at multiple occasions throughout the year while considering children's perceptions and experiences of food insecurity in addition to parental reports.

Background: The increasing numbers of colonias along the U.S.-Mexico border are characterized by disproportionately poor families of Mexican-origin, limited access to resources and health services, and heightened risk for obesity and diabetes. Despite consistent evidence supporting physical activity (PA) in prevention of chronic diseases, many individuals of Mexican-origin, including children, fail to meet PA recommendations. Environmental influences on PA, founded in ecological and social cognitive perspectives, have not been examined among children living in colonias. The purpose of this study was to identify and better understand (1) household and neighborhood environmental PA resources/supports, (2) perceived barriers to engaging in PA, and (3) PA offerings, locations, and transportation characteristics for Mexican-origin children living in colonias., Methods: Data for this study were collected by promotora-researchers (indigenous community health workers trained in research methods) using face-to-face interviews conducted in Spanish. The sample consists of 94 mother-child dyads from Texas border colonias in Hidalgo County. Interviews included questionnaire items addressing PA barriers, household and neighborhood environmental support assessments conducted with each dyad, and open-ended questions that were coded to identify availability and locations of PA opportunities and transportation options. Descriptive statistics were calculated and differences between genders, birth countries, and BMI categories of children were determined using chi-square tests., Results: All children were of Mexican-origin. The most frequently reported barriers were unleashed dogs in the street, heat, bad weather, traffic, no streetlights, and no place like a park to exercise. Prominent locations for current PA included schools, home, and parks. Common PA options for children were exercise equipment, running, playing, and sports. Environmental assessments identified exercise equipment (bicycles/tricycles, balls, etc.…), paved/good streets, yard/patio space, and social norms as the most frequent household or neighborhood resources within these colonias. Differences in PA barriers, options, and environmental resources for genders, birth countries, and BMI categories were detected., Conclusions: This study suggests that PA environmental resources, barriers, and opportunities for colonias children are similar to previous studies and distinctively unique. As expected, built resources in these communities are limited and barriers exist; however, knowledge of PA opportunities and available PA resources within colonias households and neighborhoods offers insight to help guide future research, policy, and PA initiatives.

Background: Food insecurity among Mexican-origin and Hispanic households is a critical nutritional health issue of national importance. At the same time, nutrition-related health conditions, such as obesity and type 2 diabetes, are increasing in Mexican-origin youth. Risk factors for obesity and type 2 diabetes are more common in Mexican-origin children and include increased intakes of energy-dense and nutrient-poor foods. This study assessed the relationship between children's experience of food insecurity and nutrient intake from food and beverages among Mexican-origin children (age 6-11 y) who resided in Texas border colonias., Methods: Baseline data from 50 Mexican-origin children were collected in the home by trained promotora-researchers. All survey (demographics and nine-item child food security measure) and 24-hour dietary recall data were collected in Spanish. Dietary data were collected in person on three occasions using a multiple-pass approach; nutrient intakes were calculated with NDS-R software. Separate multiple regression models were individually fitted for total energy, protein, dietary fiber, calcium, vitamin D, potassium, sodium, Vitamin C, and percentage of calories from fat and added sugars., Results: Thirty-two children (64%) reported low or very low food security. Few children met the recommendations for calcium, dietary fiber, and sodium; and none for potassium or vitamin D. Weekend intake was lower than weekday for calcium, vitamin D, potassium, and vitamin C; and higher for percent of calories from fat. Three-day average dietary intakes of total calories, protein, and percent of calories from added sugars increased with declining food security status. Very low food security was associated with greater intakes of total energy, calcium, and percentage of calories from fat and added sugar., Conclusions: This paper not only emphasizes the alarming rates of food insecurity for this Hispanic subgroup, but describes the associations for food insecurity and diet among this sample of Mexican-origin children. Child-reported food insecurity situations could serve as a screen for nutrition problems in children. Further, the National School Lunch and School Breakfast Programs, which play a major beneficial role in children's weekday intakes, may not be enough to keep pace with the nutritional needs of low and very low food secure Mexican-origin children.

Background: Trends of increasing obesity are especially pronounced among Mexican-origin women. There is little understanding of dietary patterns among U.S.- and Mexico-born Mexican-origin individuals residing in new-destination immigrant communities in the United States, especially behaviors related to obesity, such as consumption of sugar-sweetened beverages (SSB) and fast-food meals (FFM)., Methods: The study used survey data of 599 adult Mexican-origin women from the 610 women who completed the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA), which was completed in person by trained promotora-researchers in 44 colonias near the Texas border towns of Progreso and La Feria. Data included demographic characteristics (age, education, nativity or country of birth, household income, household composition, and employment status), access to transportation, self-reported height and weight, food and nutrition assistance program participation, and consumption of SSB and FFM. Descriptive statistics were calculated by nativity (U.S.-born vs. Mexico-born); multivariable linear regression models were estimated for correlates of consumption of SSB and FFM., Results: There are three major findings related to nativity. First, U.S.-born women consumed more SSB and FFM than Mexican-born counterparts in the same areas of colonias. Second, in the combined sample and controlling for other population characteristics, being born in Mexico was independently associated with FFM (fewer FFM), but not with SSB. Third, in analyses stratified by nativity, FFM and SSB were associated with each other among both nativity groups. Among Mexico-born women only, age, presence of a child, or being a lone parent was significantly associated with SSB; full-time employment, being a lone parent, and SSB consumption were each independently associated with increased frequency of FFM., Conclusions: Our analyses revealed differences in prevalence and correlates of SSB and FFM based on country of birth. Nativity, as a proxy for acculturation, may indicate the extent that immigrants have adopted behaviors from their new environment. However, nativity could also indicate limited accessibility to resources such as food/nutrition assistance programs, transportation, and proper documentation. Additionally, future research should focus on expanding our understanding of the meaning of nativity among individuals who share common contextual factors, but may have different life course experiences and resources needed to transition into a new place. Additional measures should be considered such as educational and occupational background, migration history, documentation status, and dietary acculturation, which may better explain heterogeneity within Hispanic subgroups.

The availability of an adequate household food supply is critical for the older population. There is little work that has examined food security and the influence of nativity on food security among older Mexican Americans living along the Texas-Mexico border. Using data from 140 older women (age ≥ 50 y) who participated in the 2009 Colonia Household and Community Food Resource Assessment (C-HCFRA), we examined demographic characteristics, health characteristics, food access and mobility, federal and community food and nutrition assistance programs, quality of food environment, food security, eating behaviors, and alternative food sources. 77% of participants experienced food insecurity, with 68% experiencing very low food security. Very low food security was associated with being born in Mexico, adjusting for household income and food assistance program participation. This article provides compelling evidence for enhanced research efforts that will better understand coping strategies and the use of food and nutrition assistance programs for reducing hardship associated with very low food security among older U.S.- and Mexico-born Mexican American women.
