The Effects of Income Inequality and Income Level on Mortality Vary by Population Size in Texas Counties

OBJECTIVES This study uses the counties of Texas to empirically test the predictions of Wilkinsons theory on the role of income and inequality in explaining health differentials in populations. Wilkinson predicts (1) that health is affected more by income inequality than average income in areas with large population, and (2) that health is affected more by average income than income inequality in areas with small population. We investigate how large the population of a unit must be for income inequality within the unit to affect mortality. METHODS Measures of income inequality were computed from the 1990 U.S. census data and mortality was computed from Vital Statistics data. Poisson regressions estimated the age-adjusted relative risk of the top quintile relative to the bottom quintile for equality and for income among selections of Texas counties based on population size. County ethnic composition, educational level, and health care access were controlled for. RESULTS Among counties with populations greater than 150,000, the risk of death was lower in counties with more equal income distribution than in counties with less equal income distribution. Among counties with population less than 150,000, median income affected relative risk in counties with less than 30 percent Hispanics, but not in those with more than 30 percent Hispanics. CONCLUSIONS This study provides some support for the predictions of Wilkinsons theory.

Initiation of and Barriers to Prenatal Care Use Among Low-Income Women in San Antonio, Texas

Abstract Healthy People 2010 goals set a target of 90% of mothers starting prenatal care in the first trimester of pregnancy. While there are questions about the value of prenatal care (PNC), there is much observational evidence of the benefits of PNC including reduction in maternal, fetal, perinatal, and infant deaths. The objective of this study was to understand barriers to PNC as well as factors that impact early initiation of care among low-income women in San Antonio, Texas. A survey study was conducted among low-income women seeking care at selected public health clinics in San Antonio. Interviews were conducted with 444 women. Study results show that women with social barriers, those who were less educated, who were living alone (i.e. without an adult partner or spouse), or who had not planned their pregnancies were more likely to initiate PNC late in their pregnancies. It was also observed that women who enrolled in the WIC program were more likely to initiate PNC early in their pregnancies. Women who initiated PNC late in pregnancy had the highest odds of reporting service-related barriers to receiving care. However, financial and personal barriers created no significant obstacles to women initiating PNC. The majority of women in this study reported that they were aware of the importance of PNC, knew where to go for care during pregnancy, and were able to pay for care through financial assistance, yet some did not initiate early prenatal care. This clearly establishes that the decision making process regarding PNC is complex. It is important that programs consider the complexity of the decision-making process and the priorities women set during pregnancy in planning interventions, particularly those that target low-income women. This could increase the likelihood that these women will seek PNC early in their pregnancies.

African Americans and Women Have the Highest Stroke Mortality in Texas

BACKGROUND AND PURPOSE Hispanic American (HA), African American (AA), and non-Hispanic white (NHW) populations are well represented in Texas. The Texas HA population is 95% Mexican American, affording comparison with other Hispanic populations. From risk factor profiles we expected stroke mortality to be highest in AAs and HAs. We also expected stroke mortality to be considerably higher for men than for women based on previous data. METHODS We used International Classification of Diseases, 9th Revision, codes 430 to 438 to search Texas vital statistics data for the 5-year period from 1988 through 1992. Race/ethnic differences are presented in age- and sex-specific format to avoid masking the important interaction of age and sex with stroke mortality. RESULTS Women constituted 61% of the 40,346 stroke deaths in Texas during this period. The ratio of stroke deaths for women versus men approximates the ratio of women to men in the population. AAs had a threefold to fourfold increased stroke mortality relative to NHWs at young ages. At older ages, when stroke mortality is the highest, the stroke mortality rate in NHWs approached the stroke mortality rate of AAs. HAs had a significantly higher rate of stroke mortality at younger ages relative to NHWs but a significantly lower rate at older ages. CONCLUSIONS Measures to prevent stroke mortality should emphasize its predilection for young AAs and women. A rigorous surveillance project is needed to determine whether stroke mortality is underestimated in the HA population.

Community Readiness to Prevent Intimate Partner Violence in Bexar County, Texas

The purpose of this article is to describe the Community Readiness Model implemented by the San Antonio Safe Family Coalition in Bexar County, Texas, a coordinated community response to prevent intimate partner violence. The project used a participatory action process to (a) determine the citys and countys stage of readiness to prevent intimate partner violence; (b) identify differences in the city and county by dividing the area into sectors for the assessment; (c) engage the community in determining the accuracy and usefulness of the results of the assessment; (d) develop targeted strategies to move the city and county to a higher stage of readiness for prevention of intimate partner violence; and (e) evaluate the results of the project.

Cultivating a cycle of trust with diverse communities in practice-based research: A report from PRIME net

PURPOSE Practice-based research networks (PBRNs) are increasingly seen as important vehicles to translate research into practice, although less is known about the process of engaging diverse communities in PBRN research. The objective of this study was to identify strategies for successfully recruiting and retaining diverse racial/ethnic communities into PBRN research studies. METHODS This collaborative, multisite study engaged 5 of the 8 networks of the PRImary care MultiEthnic Network (PRIME Net) consortium that conducts research with traditionally underrepresented/underserved populations. We used a sequential, qualitative research design. We first conducted 1 key informant interview with each of 24 researchers experienced in recruiting research participants from 5 racial/ethnic communities (African American, Arab/Chaldean, Chinese, Hispanic, and Native American). Subsequently, we conducted 18 focus groups with 172 persons from these communities. RESULTS Participants’ comments indicated that successful recruitment and retention of underrepresented populations in PBRN studies is linked to the overall research process. This process, which we termed the cycle of trust, entailed developing and sustaining relationships of trust during 4 interrelated stages: before the study, during study recruitment, throughout study conduct, and after study completion. Participants identified a set of flexible strategies within each stage and called for close engagement with clinic and community partners. CONCLUSIONS Our participants suggest that approaches to research that lay a foundation of trust, demonstrate respect for community members, and extend beyond the enrollment and data collection phases are essential to enhance the participation of diverse populations in PBRN research. These findings offer the PBRN community a guide toward achieving this important goal.

Use of Community Engagement Strategies to Increase Research Participation in Practice-based Research Networks (PBRNs)

Purpose: Practice-based research networks (PBRNs) are increasingly encouraged to use community engagement approaches. The extent to which PBRNs engage clinic and community partners in strategies to recruit and retain participants from their local communities (specifically racial/ethnic communities) is the focus of this study. Methods: The design was a cross-sectional survey of PBRN directors in the United States. Survey respondents indicated whether their research network planned for, implemented, and has capacity for activities that engage clinic and community partners in 7 recommended strategies organized into study phases, called the cycle of trust. The objectives of the national survey were to (1) describe the extent to which PBRNs across the United States routinely implement the strategies recommended for recruiting diverse patient groups and (2) identify factors associated with implementing the recommended strategies. Results: The survey response rate was 63%. Activities that build trust often are used more with clinic partners than with community partners. PBRNs that adopt engagement strategies when working with clinic and community partners have less difficulty in recruiting diverse populations. Multivariate analysis showed that the targeting racial/ethnic communities for study recruitment, Clinical and Translational Science Award affiliation, and planning to use community engagement strategies were independent correlates of PBRN implementation of the recommended strategies. Conclusion: PBRNs that successfully engage racial/ethnic communities as research partners use community engagement strategies. New commitments are needed to support PBRN researchers in developing relationships with the communities in which their patients live. Stable PBRN infrastructure funding that appreciates the value of maintaining community engagement between funded studies is critical to the research enterprise that values translating research findings into generalizable care models for patients in the community.

Parents' perspectives on their children's health insurance: plight of the underinsured.

OBJECTIVES To determine the prevalence and correlates of childrens underinsurance within a primary care, practice-based research network. STUDY DESIGN A survey of 13 practices within the Southwestern Ohio Ambulatory Research Network using the Medical Expenses for Children Survey in 2009 and 2010 yielded a sample of 2972 parents of children >6 months old with health insurance in the previous 12 months. Data were analyzed using bivariate and loglinear model analyses. RESULTS Of the study children, 17.2% were classified as underinsured because of their inability to pay for ≥ 1 of their pediatricians recommendations for care in the past 12 months. In addition, 15.5% reported it was harder to get medical care for their child in the past 3 years, and 6.5% indicated that their childs health had suffered. Multivariate analysis reveals complex relationships among the 3 factors related to ability to obtain care and between these factors and sociodemographic and health status factors. Across education and income categories, the underinsured rate ranged from 57% to 93% for parents who reported their childs health had suffered. CONCLUSIONS One in 6 parents reported that their child was underinsured. A similar percentage reported that it had become more difficult to get needed medical care over the past 3 years. The relationship between the perception that an underinsured childs health has suffered is much stronger for the highest socioeconomic category in this sample than for the other categories; 93% of these families were underinsured in 2009. It is possible that high deductible features of insurance plans contribute to these circumstances.

Patterns in Vegetable Consumption: Implications for Tailored School Meal Interventions.

BACKGROUND Vegetable consumption is a challenging behavioral target; consumption rates are below recommended levels and when interventions produce improvements, increases in vegetable consumption are typically a fraction of the change in fruit consumption. We describe vegetable consumption within Ohio school meals and examine how fruit selection, the more popular item, impacts vegetable consumption. METHODS Fruit and vegetable waste was collected on 11,250 trays from 17 elementary and 16 middle/high schools, using the quarter-waste visualization method. RESULTS One in 4 students ate at least a one-fourth of a cup of vegetables with their school lunch. Consumption was the highest (30.8%) in elementary school buildings with a majority of regular priced meals. Fruit selection was associated with vegetable consumption (p < .001). Middle/high school students who consumed a fruit were 88% more likely to consume a vegetable as oppose to waste it (95% CI: 1.45-2.42). Fruit selection was also associated with not selecting a vegetable, but the association was of a lower magnitude (odds ratio 1.32; 95% CI: 1.06-1.64). Trends were similar in elementary schools. CONCLUSIONS Fruit and vegetable consumption should be approached as 2 distinct behaviors with particular attention given to vegetables. Fruit items can be leveraged, though, as a means to encourage vegetable selection.
