Examining the role of acculturation in health behaviors of older Mexican Americans.

OBJECTIVES: To determine if acculturation is associated with smoking, alcohol use, and physical activity among older Mexican Americans. METHODS: Multivariate analyses of data from the Hispanic Established Populations for the Epidemiologic Studies of the Elderly (H-EPESE) were used. RESULTS: Those who were more proficient in English were more likely to be former or current smokers than nonsmokers and former or current drinkers than abstainers. In addition, those who had greater contact with Anglo-Americans were more likely to be former or current smokers than nonsmokers and former or current drinkers than abstainers. CONCLUSIONS: These results can assist health promotion programs in identifying those most at risk of engaging in negative health behaviors.

Neighborhood context and self-rated health in older Mexican Americans.

PURPOSE: To determine whether neighborhood characteristics are associated with self-rated health in older Mexican Americans. METHODS: Epidemiologic data on 3050 older Mexican Americans residing in the southwestern United States during 1993 and 1994 were merged with 1990 US Census data. All subjects were matched to one of 210 census tracts (neighborhoods). Multilevel ordinal logit models were used to examine relationships between self-rated health and individual- and neighborhood-level variables. RESULTS: After adjusting for individual characteristics, older Mexican Americans were more likely to rate their health poorer if they lived in neighborhoods that were economically disadvantaged, less populated by other Hispanics, or located within 50 miles of the US-Mexico border. In addition, residence in a border community moderated the relationship between self-rated health and neighborhood economic disadvantage. The effect of neighborhood economic disadvantage on poorer self-rated health was two to three times stronger for subjects living near the border region than subjects living further away from the border. CONCLUSIONS: This study demonstrates the importance of considering several dimensions of neighborhood context, especially for Mexican Americans. Residence in a border community and neighborhood economic disadvantage were important predictors of poorer self-rated health status. In addition, older Mexican Americans experience a health benefit from living in neighborhoods populated with other Hispanics.

Emergency department usage by uninsured patients in Galveston County, Texas.

The number of uninsured Texas residents who rely on the medical emergency department as their primary health care provider continues to increase. Unfortunately, little information about the characteristics of this group of emergency department users is available. Using an administrative billing database, we conducted a descriptive study to examine the demographic and clinical features of 17,110 consecutive patients without medical insurance who presented to the emergency department of the University of Texas Medical Branch in Galveston over a 12-month period. We also analyzed the risk of multiple emergency department visits or hospitalization according to demographic characteristics. Twenty percent of the study population made two or more emergency department visits during the study period; 19% of the population was admitted to the hospital via the emergency department. The risk of multiple emergency department visits was significantly elevated among African Americans and increased in a stepwise fashion according to age. The risk of being hospitalized was significantly reduced among females, African Americans, and Hispanics. There was an age-related monotonic increase in the risk of hospitalization. Abdominal pain, cellulitis, and spinal disorders were the most common primary diagnoses in patients who made multiple emergency department visits. Hospitalization occurred most frequently in patients with a primary diagnosis of chest pain, nonischemic heart disease, or an affective disorder. Additional studies of emergency department usage by uninsured patients from other regions of Texas are warranted. Such data may prove helpful in developing effective community-based alternatives to the emergency department for this growing segment of our population. Local policymakers who are responsible for the development of safety net programs throughout the state should find this information particularly useful.
