Demographic and Economic Correlates of Health in Old Age

In this paper we examine disparities in the ability to function among older Americans. We place special emphasis on two goals: (I) understanding the quantitatively large socioeconomic status-health gradient, and (2) the persistence in health outcomes over long periods. We find that there exist strong contemporaneous and long-run feedbacks from health to economic status. In light of these feedbacks, it is important to distinguish among alternative sources of income and the recipient of income in the household. This research also demonstrates that health outcomes at old age are influenced by health attributes of past, concurrent, and future generations of relatives. Finally, we find that the demographic and economic differences that exist among them explain functional health disparities by race and ethnicity, but not by gender.

SOCIOECONOMIC, CULTURAL, AND BEHAVIORAL FACTORS AFFECTING HISPANIC HEALTH OUTCOMES

Evidence suggests that social and economic factors are important determinants of health. Yet, despite higher porverty rates, less education, and worse access to health care, health outcomes of many Hispanics living in the United States today are equal to, or better than, those of non-Hispanic whites. This paradox is described in the literature as the epidemiological paradox or Hispanic health paradox. In this paper, the authors selectively review data and research supporting the existence of the epidemiological paradox. They find substantial support for the existence of the epidemiological paradox, particularly among Mexican Americans. Census undercounts of Hispanics, misclassification of Hispanic deaths, and emigration of Hispanics do not fully account for the epidemiological paradox. Identifying protective factors underlying the epidemiological paradox, while improving access to care and the economic conditions among Hispanics, are important research and policy implications of this review.

Appropriateness of the Decision to Transfer Nursing Facility Residents to the Hospital

OBJECTIVES: To develop and test a standardized instrument, the purpose of which is to assess (1) whether skilled nursing facilities (SNFs) transfer residents to emergency departments (ED) inappropriately, (2) whether residents are admitted to hospitals inappropriately, (3) and factors associated with inappropriate transfers.

RACE, ETHNICITY, AND NIH RESEARCH AWARDS

NIH research project grants from 2000 to 2006 show evidence of racial/ethnic disparities in the probability of receiving an award. We investigated the association between a U.S. National Institutes of Health (NIH) R01 applicant’s self-identified race or ethnicity and the probability of receiving an award by using data from the NIH IMPAC II grant database, the Thomson Reuters Web of Science, and other sources. Although proposals with strong priority scores were equally likely to be funded regardless of race, we find that Asians are 4 percentage points and black or African-American applicants are 13 percentage points less likely to receive NIH investigator-initiated research funding compared with whites. After controlling for the applicant’s educational background, country of origin, training, previous research awards, publication record, and employer characteristics, we find that black applicants remain 10 percentage points less likely than whites to be awarded NIH research funding. Our results suggest some leverage points for policy intervention.

The Prevalence of Functional Limitations and Disability in Older Persons in the US: Data from the National Health and Nutrition Examination Survey III

OBJECTIVE: To provide estimates by sex and age and by sex and race/ethnicity of the proportion of older Americans who have difficulty with functional limitations and daily activities.

Insurance coverage for prescription drugs: effects on use and expenditures in the Medicare population.

BACKGROUND Although most of the elderly are covered by Medicare, they potentially face large out-of-pocket costs for their health care because of excluded services. Aside from nursing home care, the exclusion of prescription drugs is one of the most significant. Several earlier policy initiatives have proposed adding prescription drug coverage to the Medicare program. To determine the effects of such an expansion, one must account for the potential increase in the demand for prescription drugs from providing insurance coverage. METHODS The study uses a new data source, the RAND Elderly Health Supplement to the 1990 Panel Study of Income Dynamics (PSID). The endogenity of insurance coverage is tested using instruments that exploit the longitudinal nature of the data. Equations are estimated on 910 persons (> or = 66 years) using a two-part model. RESULTS Insurance coverage for prescription drugs significantly increases the probability of use, but not of total expenditures, among those who use prescription drugs. However, insurance coverage significantly lowers out-of-pocket expenditures, thereby decreasing the financial burden on elderly households associated with prescription drug use. Medicaid coverage has effects that are smaller than those for private insurance, but the magnitude is less precisely estimated. These findings imply that if prescription drug coverage were added to Medicare, expected expenditures on drugs would rise by on average

Health status, health insurance, and health care utilization patterns of immigrant Black men.

OBJECTIVES We examined racial/ethnic differences in the seroprevalence of selected infectious agents in analyses stratified according to risk categories to identify patterns and to determine whether demographic, socioeconomic, and behavioral characteristics explain these differences. METHODS We analyzed data from the third National Health and Nutrition Examination Survey, comparing differences among groups in regard to the prevalence of infection with hepatitis A, B, and C viruses, Toxoplasma gondii, Helicobacter pylori, and herpes simplex virus type 2. RESULTS Racial/ethnic differences were greater among those in the low-risk category. In the case of most infectious agents, odds associated with race/ethnicity were almost 2 times greater in that category than in the high-risk category. CONCLUSIONS Stratification and adjustment for socioeconomic factors reduced or eliminated racial/ethnic differences in the prevalence of infection in the high-risk but not the low-risk group, wherein race/ethnicity remained significant and might have been a surrogate for unmeasured risk factors.
