Delayed Effects of Obese and Overweight Population Conditions on All-Cause Adult Mortality Rate in the USA.

Currently, there are few studies separating the linkage of pathological obese and overweight body mass indices (BMIs) to the all-cause mortality rate in adults. Consequently, this paper, using annual Behavioral Risk Factor Surveillance System data of the 50 US states and the District of Columbia, estimates empirical regression models linking the US adult overweight (25 ≤ BMI < 30) and obesity (BMI ≥ 30) rates to the all-cause deaths rate. The biochemistry of multi-period cumulative adiposity (saturated fatty acid) from unexpended caloric intakes (net energy storage) provides the natural theoretical foundation for tracing unhealthy BMI to all-cause mortality. Cross-sectional and panel data regression models are separately estimated for the delayed effects of obese and overweight BMIs on the all-cause mortality rate. Controlling for the independent effects of economic, socio-demographic, and other factors on the all-cause mortality rate, our findings confirm that the estimated panel data models are more appropriate. The panel data regression results reveal that the obesity-mortality link strengthens significantly after multiple years in the condition. The faster mortality response to obesity detected here is conjectured to arise from the significantly more obese. Compared with past studies postulating a static (rather than delayed) effects, the statistically significant lagged effects of adult population BMI pathology in this study are novel and insightful. And, as expected, these lagged effects are more severe in the obese than overweight population segment. Public health policy implications of this social science study findings agree with those of the clinical sciences literature advocating timely lifestyle modification interventions (e.g., smoking cessation) to slow premature mortality linked with unhealthy BMIs.

Parent caregiving choices of middle-generation Blacks and Whites in the United States.

OBJECTIVE: This study compares how middle-generation caregivers and non-caregivers differ by race and explores racial differences in activities of daily living (ADL), instrumental activities of daily living (IADL), and financial assistance that middle-generation caregivers provide for their parents. METHOD: Using 2000 Health and Retirement Study data, racially stratified descriptive analyses and logistic regression models for ADL, IADL, and financial assistance are presented. RESULTS: Parental need and race influence support, with similar patterns of Black and White ADL support, but racial differences in IADL and financial support. Having more children motivates Whites to increase IADL support and reduce financial support; more children decreases Blacks' IADL support. Sibling caregiver networks influence IADL and financial support in ways that vary by race. The number employed is a key determinant for Blacks for all support, but only influences White ADL support. DISCUSSION: The findings of this article indicate the importance of sample stratification by race and that employment or other subsidies may aid the expansion of caregiving by middle-generation adults.

Healthy life expectancy for selected race and gender subgroups: the case of Tennessee.

OBJECTIVE: To analyze healthy life expectancy (HLE) for major racial and gender subgroups, based on the diverse population of Tennessee and compared with the United States. MATERIALS AND METHODS: We use life table methodology and the HLE calculation model of the National Center for Health Statistics (NCHS), using two databases for 2001: NCHS National Vital Statistics Reports life tables and CDC Behavioral Risk Factor Surveillance System (BRFSS) survey. RESULTS: For Tennessee, although average total life expectancy (TLE) is 73.6 years at birth, only 61.1 years of "good" health are expected. Substantial racial and gender differences are found in both TLEs and HLEs with black males having the lowest and white females the highest. Although females have longer TLE, they spend more years in an unhealthy state than males. CONCLUSIONS: The findings raise new challenges for researchers and health policy makers for accomplishing the dual goals of longer life expectancy and elimination of health disparities among population subgroups.

Where are the airlines headed? Implications of airline industry structure and change for consumers.

The airline industry is undergoing unprecedented change. This paper explores the consumer impacts of recent airline industry change, in the context of its oligopoly market structure and current industry environment. Economic and noneconomic events, increasing competition from low-fare carriers, technological developments, and changes in industry practices are transforming consumer travel and interaction with airlines. Consumers can anticipate more direct flights, increased price transparency, and increased fees and time cost of security.

Technical efficiency in the use of health care resources: a comparison of OECD countries.

Our paper analyzes technical efficiency in the production of aggregate health outcomes of reduced infant mortality and increased life expectancy, using Organization for Economic Cooperation and Development (OECD) health data. Application of data envelopment analysis (DEA) reveals that some countries achieve relative efficiency advantages, including those with good health outcomes (Japan, Sweden, Norway, and Canada) and those with modest health outcomes (Mexico and Turkey). We conclude the USA may learn from countries more economical in their allocation of healthcare resources that more is not necessarily better. Specifically, we find that the USA can substantially reduce inputs while maintaining the current level of life expectancy.

Is there equity in the home health care market? Understanding racial patterns in the use of formal home health care.

OBJECTIVE: This article explores whether the formal home health care (HHC) market is equitable or manifests unexplained racial disparities in use. METHODS: The database is the 1994 National Long Term Care Survey. We estimate logit regression models with a race dummy variable, race interaction terms, and stratification by race. We apply the Oaxaca decomposition technique to quantify whether the observed racial gap in formal HHC use is explained by racial differences in predisposing, enabling, need, and environmental characteristics. RESULT: We find numerous unique racial patterns in HHC use. Blacks with diabetes and low income have higher probabilities of HHC use than their White counterparts. Black older persons have a 25% higher chance of using HHC than Whites. Our Oaxaca analysis indicates that racial differences in predisposing, enabling, need, and environmental characteristics account for the racial gap in use of HHC. DISCUSSION: We find that the HHC market is equitable, enhancing availability, acceptability, and accessibility of care for older Black persons. Thus, the racial differences that we find are not racial disparities.

A bibliometric analysis of health economics articles in the economics literature: 1991-2000.

This paper describes and analyzes trends in health economics articles indexed in the economics literature from 1991 to 2000, demonstrating the robust state of publication in the field during the past decade. While articles, pages, and the number of journals increased, single authorship declined dramatically from almost half of articles published to only one-third, and papers with four or more authors increased three-fold. Over three-fourths of articles were analyses of healthcare markets or health production, while policy oriented articles constituted the third largest share. Author concentration ratios decreased almost by half and the Herfindhal-Hirschman index of author concentration declined from 14 in 1991 to only 4 in 1999.
