    Latinos are the largest minority group in the United States and experience persistent disparities in access to and quality of health care. (1) To determine the relationship between nativity/immigration status and self-reported quality of care and preventive care. (2) To assess the impact of a usual source of health care on receipt of preventive care among Latinos. Using cross-sectional data from the 2007 Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic Healthcare Survey, a nationally representative telephone survey of 4,013 Latino adults, we compared US-born Latinos with foreign-born Latino citizens, foreign-born Latino permanent residents and undocumented Latinos. We estimated odds ratios using separate multivariate ordered logistic models for five outcomes: blood pressure checked in the past 2 years, cholesterol checked in the past 5 years, perceived quality of medical care in the past year, perceived receipt of no health/health-care information from a doctor in the past year, and language concordance. Undocumented Latinos had the lowest percentages of insurance coverage (37% vs 77% US-born, P < 0.001), usual source of care (58% vs 79% US-born, P < 0.001), blood pressure checked (67% vs 87% US-born, P < 0.001), cholesterol checked (56% vs 83% US-born, P < 0.001), and reported excellent/good care in the past year (76% vs 80% US-born, P < 0.05). Undocumented Latinos also reported the highest percentage receiving no health/health-care information from their doctor (40% vs 20% US-born, P < 0.001) in the past year. Adjusted results showed that undocumented status was associated with lower likelihood of blood pressure checked in the previous 2 years (OR = 0.60; 95% CI, 0.43–0.84), cholesterol checked in the past 5 years (OR = 0.62; 95% CI, 0.39–0.99), and perceived receipt of excellent/good care in the past year (OR = 0.56; 95% CI, 0.39–0.77). Having a usual source of care increased the likelihood of a blood pressure check in the past 2 years and a cholesterol check in the past 5 years. In this national sample, undocumented Latinos were less likely to report receiving blood pressure and cholesterol level checks, less likely to report having received excellent/good quality of care, and more likely to receive no health/health-care information from doctors, even after adjusting for potential confounders. Our study shows that differences in nativity/immigration status should be taken into consideration when we discuss perceived quality of care among Latinos.

      Given the persistence of health and health-care disparities among Latinos in the United States and evidence that discrimination affects health and health care, an investigation of the relationship between perceived discrimination and quality of health care among Latinos is warranted. To examine the relationship of perceived discrimination (in general and in regard to doctors and medical personnel) with self-reported quality of health care and doctor-patient communication in a nationally representative Latino population sample. Participants were 1,067 Latino adults aged ≥18 years living in the US selected via random-digit dialing. Telephone interviews were conducted in 2008 during Wave 2 of the Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic Healthcare Survey. US-born Latinos were twice as likely to report general discrimination as foreign born: 0.32 SD versus −0.23 SD (P < 0.001) on the Detroit Area Survey (DAS) discrimination scale. Higher DAS discrimination was associated with lower self-reported quality of care in US-born Latinos [OR = 0.5; 95% CI (0.3, 0.9); P = 0.009]. For foreign-born Latinos, report of any doctor or medical staff discrimination was associated with lower quality of care [OR = 0.5; 95% CI (0.3, 0.9); P = 0.03], but the DAS was not. For US-born Latinos, doctor discrimination and higher DAS were jointly associated with worse doctor-patient communication. For foreign-born Latinos, the effect of discrimination on doctor-patient communication was significantly smaller than that observed in US-born Latinos. Given the association between perceived discrimination and quality of care, strategies to address discrimination in health-care settings may lead to improved patient satisfaction with care and possibly to improved treatment outcomes.

        In California, agriculture contributes about 9% of the state’s greenhouse gas (GHG) and 72% of ammonia (NH3) emissions due to fertilizer application, livestock manure management, and enteric fermentation. California climate legislation seeks to achieve carbon neutrality and reduce GHG emissions by 85% below 1990 levels by 2045. State legislation also emphasizes the importance of increasing carbon sequestration and reducing GHG flux from natural and working lands as well as reducing emissions in the dairy and livestock sector. Ensuring the success of these policies requires further research to determine the impact of management strategies on GHG fluxes. First, I conducted seasonal field measurements of methane (CH4) on the manure storage complex of a dairy farm in the San Joaquin Valley with a mobile platform before and after anaerobic digester installation. Digester implementation strongly reduced CH4 emissions by 45.8 to 91.2% compared to pre-digester levels and show temporal variability due to differences in meteorology, on farm management practices, and digester operation. The next study analyzes soil trace gas emissions from land application of liquid dairy manure and the effect of varying soil properties, manure NH4+, and moisture conditions across California. Nitrous oxide (N2O) and ammonia (NH3) emissions ranged from 0.01 to 1.9 μg N2O-N g soil-1 and 0.3 to 32.9 μg NH3-N g soil-1 respectively and were controlled by variability in soil properties. Soil moisture conditions and manure NH4+ interacted to increase emissions. Finally, I examine greenhouse gas emissions from the soil application of solid dairy manure across soil properties and temperature conditions and compare emissions after manure biochar application and to co-application with liquid manure. Manure biochar application saw 1.9-2.5 times less normalized carbon dioxide (CO2) emissions and 4.0-4.4 times less N2O emissions compared to conventional dried solid manure application while N2O emissions were 1.6-2.2 times greater with co-application with liquid manure anaerobic digestate depending on the soil. These findings indicate how several factors interact to impact trace gas emissions from these systems and the importance of these measurements to quantify the impact of changing management practices set to better air quality and mitigate climate change.

          Federally Qualified Health Centers--commonly referred to as Community Health Centers (CHCs)--serve as a safety net for people who did not gain health insurance under the Affordable Care Act (ACA), including those immigrants not eligible for Medicaid or health insurance exchange coverage. ACA-driven changes in health insurance coverage, funding, and related policy have created new challenges for these safety net organizations. This policy brief reports the findings from analyses of the U.S. HRSA Uniform Data System and interviews conducted in 2014-16 with the leadership of 31 CHCs. The CHCs were located in communities with high concentrations of immigrants and uninsured residents, in states that either expanded Medicaid (California and New York) or that chose not to expand it (Georgia and Texas). The study found that most CHCs now see more patients, including significant numbers without insurance. The ACA has brought new resources to CHCs but has also reinforced challenges, including the need for stable revenue streams, sufficient staffing support, and assistance in leveraging new reimbursement mechanisms. Policy recommendations to address these challenges include continuing core federal funding, insuring the remaining uninsured, addressing workforce challenges, and preparing CHCs for alternative payment mechanisms.

            Little is known about the relationship between spirituality healing and perceptions about the medical encounter among Latinos. To examine the association between spirituality healing and attitudes of self-reported perceptions about the medical encounter. A cross-sectional telephone survey. 3,728 Latinos aged ≥18 years residing in the United States from Wave 1 of the Pew Hispanic Center/Robert Wood Johnson Foundation Latino Health Survey. Dependent variables were ever prayed for healing (yes/no), ever asked others to pray for healing (yes/no), considered important spiritual healing (very vs. somewhat or not important), and ever consulted a ‘curandero’ (folk healer in Latin America) (yes/no). The primary independent variables were feelings about the last time seeing a Doctor (confused by information given, or frustrated by lack of information) and perception of quality of medical care (excellent, good, fair or poor) within the past 12 months. Six percent of individuals reported that they had ever consulted a curandero, 60% prayed for healing, 49% asked others to pray for healing, and 69% considered spiritual healing as very important. In multivariable analyses, feeling confused was associated with increased odds of consulting a curandero (OR = 1.58; 95% CI, 1.02–2.45), praying for healing (OR = 1.30; 95% CI, 1.03–1.64), asking others to pray for healing (OR = 1.29; 95% CI, 1.03–1.62), and considering spiritual healing as very important (OR = 1.30; 95% CI, 1.01–1.66). Feeling frustrated by a lack of information was associated with asking others to pray for healing (OR = 1.29; 95% CI, 1.04–1.60). A better perception of quality of medical care was associated with lower odds of consulting a curandero (OR = 0.83; 95% CI, 0.70–0.98). Feelings about the medical encounter were associated with spirituality healing, praying for healing, and asking others to pray for healing. Feeling confused and perception of poor quality of medical care were associated with consulting a curandero.

              Background

              The Centers for Disease Control and Prevention (CDC) has reported that the number of new cases of HIV infection has been underreported annually by at least 40,000 cases. In 2006, the CDC recommended that voluntary HIV counseling and testing (VCT) was given to all patients aged 13 to 64 years in ambulatory care settings. The purpose of this qualitative study was to explore primary care providers' (PCP) perspectives on and experiences of facilitators and barriers to offering VCT as part of annual screening.

              Methods

              This was a descriptive, exploratory study where fifteen primary care providers were individually interviewed. Only community-based primary care providers were interviewed, and no obstetrician/gynecologists were enrolled, as VCT is standard of care in that specialty.

              Results

              Barriers included doubts about the CDC recommendation, time constraints, fear, and assumptions about age and marital status. Facilitators included normalizing HIV testing and the availability of resources and training. PCPs' role as an advocate and their professional style had the paradoxical potential of being both a barrier and a facilitator to VCT. Providers' ability to connect patients to community resources was linked to their persistence and experience.

              Conclusions

              Findings suggest more effort is needed by PCPs to facilitate HIV counseling and testing more frequently to their ambulatory care patients.

                Although exclusionary immigration policies are associated with fear of deportation and avoidance of public benefits, relationships between immigration enforcement policy and public charge policies are largely unknown. Using a California population-based survey of 1103 Asian and Latinx immigrants in 2018, we tested the relationship between immigrants experiences with law enforcement and their concern about public charge. Direct encounters with various forms of law enforcement, including being asked to show proof of citizenship by law enforcement, staying inside to avoid police or immigration officials, and having known someone who had been deported, were associated with immigrants avoidance of public benefits due to public charge concerns. Latinx immigrants were more likely to be concerns about public charge than Asians. Intersections among immigration policies deserve further consideration. There is a need to provide accurate and reliable information to immigrant communities about public benefits and advocate for inclusive immigration policies.

                  Background

                  Many conceptual frameworks that touch on immigration and health have been published over the past several years. Most discuss broad social trends or specific immigrant policies, but few address how the policy environment affects the context of settlement and incorporation. Research on the social determinants of health shows how policies across multiple sectors have an impact on health status and health services, but has not yet identified the policies most important for immigrants. Understanding the range and content of state-level policies that impact immigrant populations can focus health in all policies initiatives as well as contextualize future research on immigrant health.

                  Methods

                  Our framework identifies state-level policies across five different domains that impact the health of immigrants and that vary across states, especially for those without legal status. Our scan shows that immigrants are exposed to different contexts, ranging from relatively inclusive to highly exclusive; a number of states have mixed trends that are more inclusive in some areas, but exclusive in others. Finally, we examine how the relative inclusiveness of state policies are associated with state-level demographic and political characteristics.

                  Results

                  Contrary to the image that exclusive policies are a reaction to large immigrant populations that may compete for jobs and cultural space, we find that the higher the proportion of foreign born and Hispanics in the state, the more inclusive the set of policies; while the higher the proportion of Republican voters, the less inclusive.

                  Conclusions

                  Variation across immigrant policies is much larger than the variation in state demographic and political characteristics, suggesting that state-level policies need to be included as a possible independent, contextual effect, when assessing immigrant health outcomes. This policy framework can be particularly useful in bridging our understanding of how large macro processes are connected to the daily lives and health of immigrants.

                    To provide national prevalence estimates of usual source of healthcare (USHC), and examine the relationship between USHC and diabetes awareness and knowledge among Latinos using a modified Andersen model of healthcare access. Three thousand eight hundred and ninety-nine Latino (18-years or older) participants of the Pew Hispanic Center/Robert Wood Johnson Foundation Hispanic/Latino Health survey from the 48 contiguous United States. Cross-sectional, stratified, random sample telephone interviews. Self-reported healthcare service use was examined in regression models that included a past-year USHC as the main predictor of diabetes awareness and knowledge. Anderson model predisposing and enabling factors were included in additional statistical models. Significant differences in USHC between Latino groups were found with Mexican Americans having the lowest rates (59.7%). USHC was associated with significantly higher diabetes awareness and knowledge (OR=1.24; 95%CI=1.05-1.46) after accounting for important healthcare access factors. Men were significantly (OR=0.64; 95%CI=0.52-0.75) less informed about diabetes than women. We found important and previously unreported differences between Latinos with a current USHC provider, where the predominant group, Mexican Americans, are the least likely to have access to a USHC. USHC was associated with Latinos being better informed about diabetes; however, socioeconomic barriers limit the availability of this potentially valuable tool for reducing the risks and burden of diabetes, which is a major public health problem facing Latinos.
