A framework for evidenced-based reviews of interventions for supportive social environments

Using photovoice to explore social determinants of obesity in two underserved communities in the southeast

Over the past 25 years, the adult obesity rate in the U.S. has increased 70%, with obesity placing a disproportionate chronic disease burden on African Americans. Using Photovoice methodology, this study aimed to: (1) explore the social determinants contributing to obesity from the perspectives of residents of two low-income municipalities in Birmingham, Alabama with varying levels of segregation, (2) better understand residents' perceptions of contributors to obesity in their communities, and (3) examine residents' perceptions of interventions that might be effective in promoting positive change. Focus groups (N=10) segmented by race and community were conducted by trained moderators. Transcriptions were analyzed by theoretical thematic analysis. The study design and data analysis analyses were guided by a conceptual framework based on the Social Determinants of Obesity model. Findings from this study lend support to the efficacy of the conceptual framework as a multilevel approach describing obesity disparities in the south. Regardless of community and race, participants believed that elements of their built environment, such as fast food restaurants and unsafe walking conditions, contributed to obesity, and that schools and churches should play an active role in addressing the issue.

Accessing and Recruiting a Community-Based Sample of Men of Mexican Origin to Explore Intimate Partner Violence

INTRODUCTION

Vulnerable populations are at greater risk for the burden of disease and negative health outcomes including alcohol abuse, high-risk sexual behavior, and intimate partner violence (IPV). Moreover, health disparities experienced by vulnerable populations are mediated by socioeconomic, ethnic, and racial factors. Risk factors for IPV perpetration are exacerbated by cultural and gender norms, particularly among men of Mexican origin.

PURPOSE

To discuss research methods used in a community-based sample of men of Mexican origin and ways to overcome recruitment barriers through community engaged approaches.

DISCUSSION

Barriers can impede sampling, recruitment, and enrollment of vulnerable populations (e.g., IPV) but can be overcome. Strategies include: qualitative research methods, identifying key informants, and community engagement approaches, such as listening to the concerns of the community, incorporating the community's knowledge to inform and improve the study, and building rapport to establish trust.

CONCLUSION

Conducting research within vulnerable populations can be challenging but can be mitigated by incorporating multiple strategies. Thus, allowing researchers to gain access and valuable insight into traditionally underrepresented and understudied populations.

[Health problems and social vulnerability in immigrants admitted for an infectious disease: a case-control study]

BACKGROUND

Health resources needed by immigrants have increased steadily in the last few years. Studying health problems and social vulnerability in immigrants would help to improve the health care quality.

PATIENTS AND METHODS

A case-control study performed in the Hospital Clinic of Barcelona. Immigrant patients admitted with infectious diseases from October 2002 to September 2003 were included. Controls were paired by age, gender and HIV infection. Clinical (emergency room attendance, days and number of admission to hospital, amount of clinical procedures and drugs used during the admission, etiological and microbiological diagnosis and post-admission control) and social vulnerability variables (social worker consultation, health care card, relatives or friends caregiver, drug use, language barrier and discharge document of the nurse) were analyzed.

RESULTS

One hundred and two patients (51 cases and 51 controls, all of them males) were studied. A total of 56% were HIV-1 infected in both groups. The number of diagnostic or therapeutic procedures was higher in the immigrant group (p = 0.02), a lower proportion of patients had a final etiologic diagnosis (82% vs 98%, p = 0.021) and the number of post-discharge controls was lower (55% vs 77%, p = 0.04). Immigrants had a higher social vulnerability index than the Spanish population and 35% could not speak Spanish, French or English. The number of immigrants with health care card was lower (63% vs 94%, p < 0,0001) and a higher number needed to be admitted to a social-health care center after discharge (16% vs 2%, p = 0.01).

DISCUSSION

Social vulnerability influences the etiological diagnosis, the number of diagnostic and therapeutic procedures during the admission to the hospital and post-discharge control of immigrant population.

Projected health impact of the Los Angeles City living wage ordinance

STUDY OBJECTIVE

To estimate the relative health effects of the income and health insurance provisions of the Los Angeles City living wage ordinance.

SETTING AND PARTICIPANTS

About 10 000 employees of city contractors are subject to the Los Angeles City living wage ordinance, which establishes an annually adjusted minimum wage (7.99 US dollars per hour in July 2002) and requires employers to contribute 1.25 US dollars per hour worked towards employees' health insurance, or, if health insurance is not provided, to add this amount to wages.

DESIGN

As part of a comprehensive health impact assessment (HIA), we used estimates of the effects of health insurance and income on mortality from the published literature to construct a model to estimate and compare potential reductions in mortality attributable to the increases in wage and changes in health insurance status among workers covered by the Los Angeles City living wage ordinance.

RESULTS

The model predicts that the ordinance currently reduces mortality by 1.4 deaths per year per 10,000 workers at a cost of 27.5 million US dollars per death prevented. If the ordinance were modified so that all uninsured workers received health insurance, mortality would be reduced by eight deaths per year per 10,000 workers at a cost of 3.4 million US dollars per death prevented.

CONCLUSIONS

The health insurance provisions of the ordinance have the potential to benefit the health of covered workers far more cost effectively than the wage provisions of the ordinance. This analytical model can be adapted and used in other health impact assessments of related policy actions that might affect either income or access to health insurance in the affected population.

Feasibility and benefits of a parent-focused preschool child obesity intervention

OBJECTIVES

This field study tested the feasibility and benefits of a program to promote 6 targeted parental behaviors to prevent obesity in children served by the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC).

METHODS

Two WIC sites participated in a nonrandomized, controlled 1-year prospective study to assess parents' self-reported behavior changes.

RESULTS

Statistical analyses of preintervention and postintervention assessments of parental behavior demonstrated significant changes in 2 behaviors: frequency of offering the child water and frequency of engaging in active play with the child. In both cases, the intervention proved effective in increasing the desired behavior.

CONCLUSIONS

The findings demonstrate the feasibility of changing parental behaviors through multidimensional education in a WIC clinic setting.

Health disparities among vulnerable populations: evolution of knowledge over five decades in Nursing Research publications

BACKGROUND

Considerable attention has been focused recently on conducting research on the health disparities experienced by some Americans as the result of poverty, ethnicity, and/or marginalized social status. Nursing research has a major role to play in developing this body of knowledge.

PURPOSE

The purpose of this paper is to review the contributions that Nursing Research made through its publications over the last five decades in developing the body of tested knowledge about health disparities in vulnerable groups and to analyze the progress made.

METHODS

Criteria for reviewing the literature were established. All Nursing Research publications between 1952 and 2000 were searched manually, indexes of each year's bound volumes were reviewed, and computer searches were conducted. Included in the review were research reports, research briefs, and methodology articles.

RESULTS

Seventy-nine papers were found that met basic criteria for inclusion. The number of relevant publications increased each decade, with a sizable increase in numbers since 1990, and may be related to the social, political, and economic climate of each decade. The research questions asked and the methods used became more complex over time.

CONCLUSIONS

Nursing Research has made a significant contribution in disseminating the body of tested knowledge related to the health disparities experienced by vulnerable populations and the methodologies associated with vulnerable populations research. Areas for future research are community-based studies, intervention studies that provide tangible resources, and methodologic approaches that involve participants in the research process.
