The Household Food Insecurity and Health Outcomes of U.S.–Mexico Border Migrant and Seasonal Farmworkers

Emerging evidence suggests chronic household food insecurity has an adverse effect on health. This study examined the prevalence, predictors and health outcomes associated with food insecurity in 100 migrant and seasonal farmworker (MSFW) households living on the U.S.–Mexico border. Data were collected using the U.S. Food Security Scale, California Agricultural Worker’s Health Survey, and objective anthropometric, clinical and biochemical indicators. Food insecurity affected 82% of households; 49% also had hunger. Household food insecurity was predicted by the presence of minor children in the home and low maternal education. Food insecure households were more likely to have at least one member affected by symptoms of depression (deprimido), nervios (an ethnospecific condition), learning disorders, and symptoms suggestive of gastrointestinal infection. Although not directly associated with food insecurity, adult obesity, central body adiposity, elevated blood pressure, and blood lipid and glucose disturbances were common. These findings highlight the significant food security and health challenges faced by border area MSFW families.     

The “Latina Epidemiologic Paradox”: Contrasting Patterns of Adverse Birth Outcomes in U.S.-Born and Foreign-Born Latinas

BackgroundThe “Latina epidemiologic paradox” postulates that despite socioeconomic disadvantages, Latina mothers have a lower risk for delivering low birth weight (LBW) babies than non-Latina Whites. However, these patterns may be changing over time and may differ depending on the mother's birthplace and legal status in the United States. This study investigates differences in risk for three birth outcomes among Whites, U.S.-born Latinas, and foreign-born Latinas.MethodsWe undertook a cross-sectional study of rates of LBW, preterm, and small-for-gestational-age (SGA) births among 196,617 women delivering live, singleton births in Utah from 2004 to 2007. Each group was compared using logistic regression.ResultsU.S.-born Latinas had a similar or greater risk for all three outcomes when compared with Whites. Foreign-born Latinas had lower risk for preterm birth (odds ratio [OR], 0.85; 95% confidence interval [CI], 0.80–0.90) compared with Whites, but not for LBW and SGA; foreign-born Latinas had a lower risk for LBW (OR, 0.82; 95% CI, 0.74–0.92), preterm birth (OR, 0.81; 95% CI, 0.74–0.89), and SGA (OR, 0.91; 95% CI, 0.83–0.99) compared with U.S.-born Latinas. Among foreign-born Latinas only, there was no difference in risk between documented (i.e., those who had a legal social security number) and undocumented women for LBW, preterm birth, or SGA.ConclusionsThese data support the existence of a variation of the “Latina paradox” among Latinas according to birthplace, where U.S.-born Latinas do not experience better birth outcomes than Whites, but foreign-born Latinas experience better birth outcomes for several endpoints compared with U.S.-born Latinas. Prevention efforts may prove more effective by considering the different composition of risk factors among foreign- and U.S.-born Latina populations.     

Evidence into Policy and Practice? Measuring the Progress of U.S. and U.K. Policies to Tackle Disparities and Inequalities in U.S. and U.K. Health and Health Care

Health policy in both the United States and the United Kingdom has recently shifted toward a much greater concern with disparities and inequalities in health and health care. As evidence for these disparities and inequalities mounts, the different approaches in each country present specific challenges for policy and practice. These differences are most apparent in the mechanisms by which the progress of such policies is measured. This article compares the United States' and United Kingdom's strategies to gauge the challenges for policymakers in order to inform policy and practice. A cross-national comparison of selected measurement mechanisms identifies lessons for policy and practice in both countries.     

Review of U.S. Health Resources and Services Administration’s Find a Health Center Locator

In addition to questions about diagnoses, wellness guidelines, and treatment concerns, librarians are sometimes confronted with questions about access to care from uninsured clients. The U.S. Health Resources & Services Administration (HRSA) provides an easy-to-use online “Locator” service for its network of Federally Qualified Health Centers serving low income and/or uninsured individuals across the country. This Locator tool is an important resource for consumer health librarians serving uninsured individuals.

The Feminization of Aging: How Will This Impact on Health Outcomes and Services?

We conducted an integrative review to identify issues and challenges that face aging women and to distinguish areas for future research. We found that many older women continue to face inequities related to health and often are invisible within the discourse of aging policy. In this article we argue for a greater focus on the unique needs of women, a gendered approach to policy and intervention development, and promotion of the health of women across the life span. Policymakers, health care workers, and researchers need to consider the perspective of gender as well as age when implementing and evaluating effective interventions.     

Looking Beyond “Affordable” Health Care: Cultural Understanding and Sensitivity—Necessities in Addressing the Health Care Disparities of the U.S. Hispanic Population

Health disparities are pervasive in the United States; but among Hispanics, access to health care is encumbered by poverty, lack of insurance, legal status, and racial or minority status. Research has identified certain aspects of Hispanic culture, values, and traditions contributing to the nature of the Hispanic patient-doctor relationship and the quality of the health care service. Current educational efforts by nonprofit organizations, government, health professionals, and pharmaceutical manufacturers fail to address the needs for accessible and appropriately culture-sensitive information when approaching the diverse Hispanic community. Understanding Hispanics’ consumptive practices and expectations surrounding medications is critical to the success of many treatment regimens. Recommendations are presented to address this health care issue.     

The Role of Clinics in Determining Older Recent Immigrants’ Use of Health Services

Immigrants are ineligible for federally-funded Medicaid in the U.S. until at least 5 years after arrival. There is little information on where they receive care in light of this restriction. Using Blinder–Oaxaca decomposition, this study examines whether the setting in which older recent immigrants receive care (i.e., health clinic, emergency room or doctor’s office) explains delays in care. Among older adults with a usual source of care, 13.5% of recent immigrants had not seen a health professional in the past year compared to 8.6% of non-recent immigrants and 6.3% of native-born. Approximately 23% of these differences is attributable to recent immigrants’ tendency to receive care in clinics and community health centers. Even when older recent immigrants manage to find a usual source of care, it is of lower quality than that received by their non-recent immigrant and native-born counterparts.     

The “pumpgate” incident: Stigma against lactating mothers in the U.S. workplace

ABSTRACT

Studies conclude that breastfeeding for six months is associated with better lifelong health for the mother and the child. Mothers in the U.S. returning to work after maternity leave report difficulty with the need to take frequent breaks to pump breastmilk so many stop breastfeeding. Factors discouraging pumping breastmilk in the workplace motivated a content analysis of public comments posted in response to a legal deposition that occurred in January of 2011 in which an attorney who was a new mother was challenged about taking a break to pump breastmilk. A total of 899 public comments posted on Yahoo in 2015–2016 in response to this earlier incident were analyzed for content. Of these, only 336 mentioned breastfeeding. Overall, 148 comments showed support for breastfeeding or pumping breastmilk at work, while 182 comments showed moderate to strong disapproval (six unclassified). The majority of disapproving comments were critical of pumping breastmilk in the workplace. Implications of these findings for the duration of breastfeeding after returning to work are discussed.     

Dietary Saturated Fats and Health: Are the U.S. Guidelines Evidence-Based?

The last decade has seen nearly 20 papers reviewing the totality of the data on saturated fats and cardiovascular outcomes, which, altogether, have demonstrated a lack of rigorous evidence to support continued recommendations either to limit the consumption of saturated fatty acids or to replace them with polyunsaturated fatty acids. These papers were unfortunately not considered by the process leading to the most recent U.S. Dietary Guidelines for Americans, the country’s national nutrition policy, which recently reconfirmed its recommendation to limit saturated fats to 10% or less of total energy intake, based on insufficient and inconsistent evidence. Continuation of a cap on saturated fat intake also fails to consider the important effects of the food matrix and the overall dietary pattern in which saturated fatty acids are consumed.     

Exposure of the U.S. Population to Acrylamide in the National Health and Nutrition Examination Survey 2003–2004

Background

The lifelong exposure of the population to acrylamide has raised concerns about the possible health effects of the chemical. Data on the extent of exposure to acrylamide and its primary metabolite, glycidamide, are needed to aid in the assessment of potential health effects.

Objectives

The aim of this study was to assess human exposure to acrylamide and glycidamide in the general U.S. population through the measurement of hemoglobin adducts of acrylamide (HbAA) and glycidamide (HbGA).

Methods

HbAA and HbGA were measured in 7,166 subjects from the National Health and Nutrition Examination Survey. Stratified HbAA and HbGA data were reported by sex, age groups, race/ethnicity (Mexican American, non-Hispanic black, non-Hispanic white), and smoking status based on serum cotinine levels. Covariate-adjusted geometric means for each demographic group were calculated using multiple regression analysis.

Results

HbAA and HbGA levels ranged from 3 to 910 and from 4 to 756 pmol/g hemoglobin, respectively, with smokers having the highest levels overall. Tobacco smoke exposure in nonsmokers had a small but significant effect on HbAA and HbGA levels. Adjusted geometric mean levels for children 3–11 years of age were higher than for adults ≥ 60 years of age [mean (95% confidence interval): HbAA, 54.5 (49.1–51.5) and HbGA, 73.9 (71.3–76.6) vs. HbAA, 46.2 (44.3–48.2) and HbGA, 41.8 (38.7–45.2)]. Levels were highest in Mexican Americans [HbAA: 54.8 (51.9–57.8), HbGA: 57.9 (53.7–62.5)], whereas non-Hispanic blacks had the lowest HbGA levels [43.5 (41.1–45.9)].

Conclusions

U.S. population levels of acrylamide and glycidamide adducts are described. The high variability among individuals but modest differences between population subgroups suggest that sex, age, and race/ethnicity do not strongly affect acrylamide exposure. Adduct concentration data can be used to estimate relative exposure and to validate intake estimates.     

Exploratory Study of the Occupational Health and Health-Seeking of Migrant and Seasonal Farmworkers on the U.S.–Mexico Border

The U.S. migrant and seasonal farmworker (MSFW) workforce is aging. Aging causes functional changes that can affect work performance and increase injury/accident risk. It also has been linked with deferred health-seeking. The exploratory study was conducted to investigate occupational injuries and health-seeking in Hispanic MSFW on the U.S.-Mexico border. Data were collected using an abbreviated Spanish-version of the California Agricultural Worker Health Survey. Nearly 60% of the 141 participants were middle-aged or older. Musculoskeletal injuries and those consistent with agrochemical and environmental exposures were common. Farmworkers aged >40 years were 2.5-5 times more likely than younger MSFW to report persistent single and multiple injuries involving the knees, shoulder, feet, and hands. Except for neck and back injuries, few received any medical treatment. Although many self-treated with traditional home remedies, few used CAM practitioners. The study findings highlight the multiple workplace health and health-seeking challenges faced by aging immigrant MSFW.     

Urinary Concentrations of Metabolites of Pyrethroid Insecticides in the General U.S. Population: National Health and Nutrition Examination Survey 1999–2002

Background

Pyrethroid insecticides are the most commonly used residential insecticides in the United States.

Objectives

Our objective was to assess human exposure via biomonitoring to pyrethroid insecticides in a representative sample of the general U.S. population ≥ 6 years of age.

Methods

By using isotope-dilution high-performance liquid chromatography/electrospray chemical ionization/tandem mass spectrometry, we measured five urinary metabolites of pyrethroid insecticides in 5,046 samples collected as a part of the 1999–2002 National Health and Nutrition Examination Survey (NHANES). Univariate, multivariate, and Pearson correlation analyses were performed using SUDAAN and SAS software, incorporating the appropriate sample weights into the analyses. Multivariate analyses included age, sex, race/ethnicity, creatinine, fasting status, and urine collection time as covariates.

Results

We detected 3-phenoxybenzoic acid (3PBA), a metabolite common to many pyrethroid insecticides, in more than 70% of the samples. The least-squares geometric mean (LSGM) concentration (corrected for covariates) of 3PBA and the frequency of detection increased from 1999–2000 (0.292 ng/mL) to 2001–2002 (0.318 ng/mL) but not significantly. Non-Hispanic blacks had significantly higher LSGM 3PBA concentrations than did non-Hispanic whites and Mexican Americans in the 2001–2002 survey period and in the combined 4-year survey periods but not in the 1999–2000 survey period. Children had significantly higher LSGM concentrations of 3PBA than did adolescents in both NHANES periods and than adults in NHANES 1999–2000. Cis- and trans-(2,2-dichlorovinyl)-2,2-dimethylcyclopropane-1-carboxylic acid were highly correlated with each other and with 3PBA, suggesting that urinary 3PBA was derived primarily from exposure to permethrin, cypermethrin, or their degradates.

Conclusions

Pyrethroid insecticide exposure in the U.S. population is widespread, and the presence of its metabolites in the urine of U.S. residents indicates that children may have higher exposures than adolescents and adults.
