Body image and physical activity among Latina and African American women.

OBJECTIVES: Obesity in African American (AA) and Hispanic or Latina (HL) women has been partly attributed to low physical activity (PA) and cultural influences on body image. The purpose of this study was to determine the relationship among body mass index (BMl=kg/m2), body image perception (perceived and desired) and PA. DESIGN: The current study is a cross-sectional, secondary data analysis of the Health Is Power (HIP) project (1R01CA109403). SETTING: Women residing in Harris County, Houston and Travis County, Austin, Texas were recruited to participate in the study. PARTICIPANTS: Over four hundred (N=410) AA (N=262) and HL (N=148) women participated in the HIP project and were included in the current study. MAIN OUTCOME MEASURES: BMI, Pulvers' body image, PA and demographic data were collected from each participant. RESULTS: Women (mean age=45.2 yrs) were educated (44% college graduates) and obese (mean BMI =34.6 kg/m2). Less than half perceived themselves correctly regardless of actual weight and ethnicity (P<.001). Nearly three-fourths of AA (73.9%) and less than half of HL (42.9%) women who were normal weight desired to be obese, and only 39.4% of AA and HL women desired to be normal weight. Women varied on measures of PA (P<.05). Regression analyses showed objectively measured PA was significantly associated with BMI and ethnicity (P<.01). CONCLUSIONS: Results reveal dichotomous distortion in body images. Women need strategies to perceive normal weight as desirable for health and beauty, leading to increased PA and reducing obesity.

Education for the public health profession: a new look at the Roemer proposal.

Demands for a high level of professionalism in public health practice, and concomitant strengthening of public health education to match 21st-century community challenges provide an opportunity to reconsider the current paradigm for professional degrees in public health. In this article, we consider whether the currently typical public health education meets the requirements of a professional education, examine the current state of public health education, and provide a rationale for renewed emphasis on the doctor of public health (DrPH) degree. We also present one potential three-year DrPH curriculum to stimulate further discussion, while acknowledging the multiple challenges that face any school of public health moving to implement such an education.

Professionalism and ethics in the public health curriculum.

As the public's health-care needs increase in complexity, renewed attention is being given to the ethical dimensions of public health decision-making and the development of public health ethics as a bounded area of teaching and research. This article provides an overview of approaches to public health ethics and decision-making, and suggests ways to incorporate the professionalism competencies into the teaching of public health practice. The teaching of ethics language, concepts, and tools for decision analysis helps to prepare students for the inevitable ethical choices they will have to make in their professional practice. The teaching of ethics and professionalism and the experiences of professionals enrich each other and foster the critical link between education and practice.

Migration history, health behaviors, and cardiovascular disease risk factors in overweight Mexican-American women.

PURPOSE: This research examined whether the migration history of overweight Mexican-American women had an independent effect on cardiovascular risk factors, or whether it was mediated by health behavior changes. DATA AND METHODS: Cross-sectional data from 390 overweight, non-diabetic Mexican-American women (aged 18 to 65 years), all recruited from Starr County, Texas, were used for this analysis. Migration history was inferred from birthplaces of subjects and relatives, and length of residence in the United States. Health behaviors included tobacco and alcohol use, sleeping, exercise, and dietary practices. The cardiovascular disease risk factor variables (CDRFVs) studied were plasma glucose, abdominal obesity, blood pressures, and blood lipids. A migration history score (MHS) was developed from factor analysis, almost equally contributed to by the 9 migration history variables. Healthy habits were defined by 6 variables, and 3 factors (blood pressures, lipids/glucose, and body fat/glucose) were used for the CDRFVs. FINDINGS AND CONCLUSION: MHS was correlated positively with socioeconomic status, and negatively with family stress. Older women had healthier drinking and sleeping habits. Women with a higher migration history score exhibited poorer exercise habits, and increased blood pressures. After adjusting for the effect of healthy exercise habits on blood pressures, the impact of migration history on blood pressures became non-significant (P>.05), leading to the conclusion that healthy exercise behaviors mediated the negative relationship of MHS with blood pressures. Age was independently positively correlated with all CDRFVs. Age also weakly moderated the negative relationship of MHS and healthy exercise habits.

Health promotion attitudes and practices of Texas nurse practitioners.

PURPOSE: The purpose of this descriptive cross-sectional survey was to examine the health promotion attitudes and practices of Texas nurse practitioners (NPs). DATA SOURCES: Original research utilizing the Health Promotion Practices of Nurse Practitioners Instrument developed by the researcher and completed by 442 Texas NPs. CONCLUSIONS: Overall, Texas NPs have positive attitudes toward health promotion and are supportive of health promotion practices. However, the findings of this study indicate that improvement can be made in the adoption of certain health promotion practices. IMPLICATIONS FOR PRACTICE: The growing number of NPs providing care to patients can significantly impact public health through consistent health promotion in clinical practice.

Clinical, sociodemographic, and local system factors associated with a hospital death among cancer patients.

OBJECTIVE: The study was conducted to examine factors associated with hospital deaths among a group of cancer patients. PATIENTS AND METHODS: A retrospective chart review of the M. D. Anderson Cancer Center Tumor Registry was conducted. Participants were all adult cancer patients, residents of the State of Texas diagnosed and treated since January 1, 1990, and who died during the years 1999 and 2000. The study outcome was the site of death. MAIN RESULTS: The inclusion criteria were met by 866 patients of whom 504 (58%) died in a hospital. The group included 489 (56%) men. A number of 641 (74%) were White, 104 (12%) Hispanic, 92 (11%) Black, and 29 (3%) of other origin. The majority, 501 (58%), had been diagnosed with stage IV disease, and the median survival time was 14 months. Multivariate logistic regression analysis showed patients diagnosed with hematologic cancers to be significantly more likely (p<0.001) of dying in hospitals, odds ratio [OR 2.88] and confidence interval [95% CI 1.79-4.63], women diagnosed with breast and gynecological cancers were significantly less likely (p=0.03) of dying at hospitals odds ratio [OR 0.64] and confidence interval [95% CI 0.42-0.96], when compared with patients diagnosed with other cancers. Lower household income per zip code of residency was marginally associated (p=0.06) with hospital deaths. CONCLUSIONS: The study identified groups of cancer patients at risk of hospital death. These results should account when planning the allocation of hospital palliative care services as well as when informing policy decisions about health care financing and delivery of these services.

Ethical issues in conducting migrant farmworker studies.

Migrant farmworkers should be considered a vulnerable population because they work in a hazardous industry, are often members of an ethnic minority, have known difficulty in accessing health care, and are often of lower socioeconomic status. For these reasons, too, it is extremely important to conduct health-related research with this often-underserved group. However, because migrant farmworkers are vulnerable, investigators must be especially vigilant in protecting them from the potential harms of research and in ensuring that the special ethical issues that arise in research with this population are identified and addressed for every project. In response to the National Cancer Institute's concerns about the feasibility of conducting epidemiologic studies among migrant farmworkers, researchers undertook four feasibility studies near the Texas-Mexico border. Each study raised different, complex ethical questions that challenged the investigators, but whose resolution turned out to be crucial to the success of the studies.
