Health care expenditure burdens among elderly adults: 1987 and 1996.

OBJECTIVES: Concerns about the health care expenditure burdens of elderly adults underlie the ongoing debate over expanding Medicare benefits and strengthening Medicare+Choice. We examine burdens for this population using data from the 1987 National Medical Expenditure Survey (NMES) and the 1996 Medical Expenditure Panel Survey (MEPS). METHODS: We estimate how frequently elderly adults live in families whose health expenditures exceed 20% or 40% of their after-tax disposable incomes. Our methodology reduces bias due to errors in income while providing an intuitive measure of exposure to the risk of high burdens. RESULTS: Despite rapid increases in medical care prices, the percentage of elderly adults facing burdens over 20% of disposable income remained essentially constant at 20.9% in 1987 and 22.9% in 1996. The percentage with burdens exceeding 40% of disposable income was 7.3% in 1987 and 7.9% in 1996. High expenditure burdens were more prevalent among elderly adults who were poorer, older, female, higher risk, and covered only by traditional Medicare. Medicaid coverage helped to reduce burdens among the elderly poor, yet incomplete Medicaid take-up in 1996 left approximately 1.3 million elderly adults eligible for Medicaid but covered only by traditional Medicare. CONCLUSIONS: Our results highlight the widespread prevalence of high health care expenditure burdens among elderly adults and the varying extent to which insurance coverage helped to protect them from rising health care expenditures between 1987 and 1996.

Booming prescription drug expenditure: a population-based analysis of age dynamics.

BACKGROUND: Prescription drug expenditures in North America have nearly doubled in the past 5 years, creating intense pressure for all public and private benefits managers and policymakers. OBJECTIVE: The objective of this study was to describe age-specific drug expenditure trends from 1996 to 2002 for the Canadian province of British Columbia. STUDY DESIGN: This study shows changes in expenditures per capita quantified for 5 age categories: residents aged 0 to 19, 20 to 44, 45 to 64, 65 to 84, and 85 and older. The cost impacts of 7 determinants of prescription drug expenditures are quantified. DATA: This study describes population-based, patient-specific pharmaceutical data showing the type, quantity, and cost of every prescription drug purchased by virtually all residents of British Columbia. RESULTS: Population-wide expenditures per capita grew at a rate of 11.6% per annum. Growth was primarily driven by the selection of more costly drugs per course of treatment and increases in the number concomitant treatments received per patient. Population aging did not have a major impact on expenditures. However, expenditure per capita grew most rapid among residents aged 45 to 64, the cohort that expended most over the period. The aging of this demographic cohort may threaten the financial viability of age-based drug benefit programs.

Trends in prescription drug expenditures by Medicaid enrollees.

OBJECTIVE: As prescription drug expenditures consume an increasingly larger portion of Medicaid budgets, states are anxious to control drug costs without endangering enrollees' health. In this report, we analyzed recent trends in Medicaid prescription drug expenditures by therapeutic classes and subclasses. Identifying the fastest growing categories of drugs, where drugs are grouped into clinically relevant classes and subclasses, can help policymakers decide where to focus their cost containment efforts. METHODS: We used data from the Medical Expenditure Panel Survey linked to a prescription drug therapeutic classification system, to examine trends between 1996/1997 and 2001/2002 in utilization and expenditures for the noninstitutionalized Medicaid population. We separated aggregate trends into changes in population with use and changes in expenditures per user, and percent generic. We also highlighted differences within the Medicaid population, including children, adults, disabled, and elderly. RESULTS: We found rapid growth in expenditures for antidepressants, antipsychotics, antihyperlipidemics, antidiabetic agents, antihistamines, COX-2 inhibitors, and proton pump inhibitors and found evidence supporting the rapid take-up of new drugs. In some cases these increases are the result of increased expenditures per user and in other cases the overall growth also comes from an increase in the population with use. CONCLUSIONS: Medicaid programs may want to reassess their cost-containment policies in light of the rapid take-up of new drugs. Our analysis also identifies areas in which more information is needed on the comparative effectiveness of new versus existing treatments.

Using the SF-12 health status measure to improve predictions of medical expenditures.

BACKGROUND: Relatively few studies have used self-reported health status in models to predict medical expenditures, and many of these have used the SF-36. OBJECTIVES: We sought to examine the ability of the briefer SF-12 measure of health status to predict medical expenditures in a nationally representative sample. METHODS: We used data from the 2000-2001 panel of the Medical Expenditure Panel Study. Respondents (n = 5542) completed the SF-12 in a questionnaire. Interviews obtained data on demographics and selected chronic conditions. Data on expenditures incurred subsequent to the interview were obtained in part from provider records. We examined different regression model specifications and compared different statistical estimation techniques. RESULTS: Adding the SF-12 to a regression model improved the prediction of subsequent medical expenditures. In a model with only age and gender, adding the SF-12 increased R from 0.06 to 0.13. The coefficients for the Physical Component Summary (PCS) and the Mental Component Summary (MCS) of the SF-12 for this model were -0.045 (P < 0.01) and -0.012 (P < 0.01), respectively. In a model including demographic characteristics, chronic conditions, and previous expenditures, adding the SF-12 increased the R from 0.26 to 0.29. The coefficients for the PCS and the MCS for this model were -0.025 (P < 0.001) and -0.005 (P = 0.15), respectively. A single general health status question performed almost as well as the full SF-12. Models estimated using ordinary least squares had undesirable properties. In terms of R, a generalized linear model (GLM) with a Poisson variance function was consistently superior to a GLM with a gamma variance function. CONCLUSIONS: Information on self-reported health status is useful in predicting medical expenditures. The extent to which the SF-12 adds predictive power over a comprehensive array of diagnostic data remains to be examined.

Impacts of informal caregiver availability on long-term care expenditures in OECD countries.

OBJECTIVE: To quantify the effects of informal caregiver availability and public funding on formal long-term care (LTC) expenditures in developed countries. DATA SOURCE/STUDY SETTING: Secondary data were acquired for 15 Organization for Economic Cooperation and Development (OECD) countries from 1970 to 2000. STUDY DESIGN: Secondary data analysis, applying fixed- and random-effects models to time-series cross-sectional data. Outcome variables are inpatient or home heath LTC expenditures. Key explanatory variables are measures of the availability of informal caregivers, generosity in public funding for formal LTC, and the proportion of the elderly population in the total population. DATA COLLECTION/EXTRACTION METHOD: Aggregated macro data were obtained from OECD Health Data, United Nations Demographic Yearbooks, and U.S. Census Bureau International Data Base. PRINCIPAL FINDINGS: Most of the 15 OECD countries experienced growth in LTC expenditures over the study period. The availability of a spouse caregiver, measured by male-to-female ratio among the elderly, is associated with a $28,840 (1995 U.S. dollars) annual reduction in formal LTC expenditure per additional elderly male. Availability of an adult child caregiver, measured by female labor force participation and full-time/part-time status shift, is associated with a reduction of $310 to $3,830 in LTC expenditures. These impacts on LTC expenditure vary across countries and across time within a country. CONCLUSIONS: The availability of an informal caregiver, particularly a spouse caregiver, is among the most important factors explaining variation in LTC expenditure growth. Long-term care policies should take into account behavioral responses: decreased public funding in LTC may lead working women to leave the labor force to provide more informal care.

Medicare expenditures for residents in assisted living: data from a national study.

OBJECTIVE: To provide preliminary data on Medicare expenditures for assisted living facility (ALF) residents and to investigate whether ALF characteristics were related to Medicare expenditures for ALF residents. DATA SOURCES/STUDY SETTING: Data from the National Study of Assisted Living for the Frail Elderly conducted in 1998-1999. This analysis was restricted to the 40 percent of ALFs in that sample that adhered to the assisted living (AL) philosophy by offering more than minimal levels of services and privacy. This study involved the approximately 1,200 residents who remained in an ALF from baseline to follow-up data collection. Six months of postbaseline Medicare claims were acquired for 545 of these residents, who did not differ significantly from the larger sample. DATA COLLECTION: Baseline individual and facility data were collected in personal interviews with residents and a combination of personal and telephone interviews with facility staff. Medicare claims data were acquired from the Centers for Medicare and Medicaid Services. STUDY DESIGN: Cross-sectional analyses using logistic and ordinary least squares regression techniques were used to determine the relationships among individual and facility characteristics and Medicare utilization and expenditures. PRINCIPAL FINDINGS: On an annualized basis, AL residents incurred Medicare costs of approximately US dollars 4,800. Just less than 15 percent of AL residents accounted for over 75 percent of total Medicare costs. Both the likelihood of utilizing Medicare-covered services and the intensity of service use were largely unaffected by the characteristics of the ALF in which residents lived. Utilization was largely a function of individual characteristics. The only exception to this general finding was that those individuals who utilized services and resided in smaller ALFs had significantly lower average expenditures than did individuals in larger ALFs. CONCLUSIONS: These preliminary data imply that both the level and distribution of Medicare expenditures among ALF residents were similar to those among the general community-dwelling Medicare beneficiary population. No significant relationships were observed between ALF characteristics and Medicare expenditures, except the effect of facility size. This result may imply that how the AL industry eventually defines itself in terms of services and amenities, other than size, may have little impact on Medicare expenditures for ALF residents. However, this is a single, initial study, so caution must be exercised when considering the implications of these results.

Government expenditures at the end of life for short- and long-stay nursing home residents: differences by hospice enrollment status.

OBJECTIVES: To examine end-of-life government expenditures for short- and long-stay Medicare- and Medicaid-eligible (dual-eligible) nursing home (NH) hospice and nonhospice residents. DESIGN: A retrospective cohort study. SETTING: Six hundred fifty-seven Florida NHs. PARTICIPANTS: Dual-eligible NH residents who died in Florida NHs between July and December 1999 (N=5,774). MEASUREMENTS: Nursing home stays of 90 days or less were considered short stays (n=1,739), and those over 90 days were long stays (n=4,035). Three diagnosis groups were studied: cancer without Alzheimer's disease or dementia, Alzheimer's disease or dementia, and other diagnoses. Eligibility and expenditure claims data for 1998 and 1999 were merged with vital statistics and NH resident assessment data to determine diagnoses, location of death, hospice enrollment, eligibility, and expenditures. RESULTS: Twenty percent of short-stay (n=350) and 26% of long-stay (n=958) NH decedents elected hospice; of these, 73% of short-stay and 58% of long-stay NH residents had hospice stays of 30 days or less. Overall, mean government expenditures in the last month of life were significantly less for hospice than nonhospice residents (7,365 dollars; 95% confidence interval (CI)=7,144-7586 dollars vs 8,134 dollars; 95% CI=7,896-8,372 dollars), but 1-month expenditures were only significantly lower for hospice residents with short NH stays, not for those with long NH stays. CONCLUSION: Overall, hospice care in NHs does not appear to increase government expenditures. Because significantly lower expenditures are observed for short-stay NH hospice residents, policy restricting access to Medicare hospice for Medicare skilled nursing facility residents may represent a missed opportunity for savings.

A need-based model to project national dental expenditures.

A national model on need for dental treatment, as measured by the HANES survey of the National Center for Health Statistics, is described and applied to determine expenditures required to provide necessary dental services under third-party funding of a national dental program. Services have been divided into five components by type of service and age of the population and expenditures are projected for each year, 1980-84. Total expenditures are projected to increase from 18.98 billion dollars in 1980 to 26.42 billion in 1984. Separate projections are also provided for each component and each service. Expenditures derived from this model are compared to direct projections of trends taking place in the current dental care system. Only minor discrepancies in total expenditures are noted but there are large differences for individual services, notably in the areas of prevention and periodontal diseases. Separate comparisons with demand-based projections derived from the experience of the California Dental Service are also presented. Again, the major differences relate to expenditures for individual services, particularly crowns, for which demand expenditures outstripped need by a three-fold margin.

Country of birth, socioeconomic position, and healthcare expenditure: a multilevel analysis of Malmö, Sweden.

STUDY OBJECTIVE: The principle of equity aims to guarantee allocation of healthcare resources on the basis of need. Therefore, people with a low income and persons living alone are expected to have higher healthcare expenditures. Besides these individual characteristics healthcare expenditure may be influenced by country of birth. This study therefore aimed to investigate the role of country of birth in explaining individual healthcare expenditure. DESIGN: Multilevel regression model based on individuals (first level) and their country of birth (second level). SETTING: The city of Malmö, Sweden. PARTICIPANTS: All the 52 419 men aged 40-80 years from 130 different countries of birth, who were living in Malmö, Sweden, during 1999. MAIN RESULTS: At the individual level, persons with a low income and persons living alone showed a higher healthcare expenditure, with regression coefficients (and 95% confidence intervals) being 0.358 (0.325 to 0.392) and 0.197 (0.165 to 0.230), respectively. Country of birth explained a considerable part (18% and 13%) of the individual differences in the probability of having a low income and living alone, respectively. However, this figure was only 3% for having some health expenditure, and barely 0.7% with regard to costs in the 74% of the population with some health expenditure. CONCLUSIONS: Malmö is a socioeconomically segregated city, in which the country of birth seems to play only a minor part in explaining individual differences in total healthcare expenditure. These differences seem instead to be determined by individual low income and living alone.

Household out-of-pocket medical expenditures and National Health Insurance in Taiwan: income and regional inequality.

BACKGROUND: Unequal geographical distribution of medical care resources and insufficient healthcare coverage have been two long-standing problems with Taiwan's public health system. The implementation of National Health Insurance (NHI) attempted to mitigate the inequality in health care use. This study examines the degree to which Taiwan's National Health Insurance (NHI) has reduced out-of-pocket medical expenditures in households in different regions and varying levels of income. METHODS: Data used in this study were drawn from the 1994 and 1996 Surveys of Family Income and Expenditure. We pooled the data from 1994 and 1996 and included a year dummy variable (NHI), equal to 1 if the household data came from 1996 in order to assess the impact of NHI on household out-of-pocket medical care expenditures shortly after its implementation in 1995. RESULTS: An individual who was older, female, married, unemployed, better educated, richer, head of a larger family household, or living in the central and eastern areas was more likely to have greater household out-of-pocket medical expenditures. NHI was found to have effectively reduced household out-of-pocket medical expenditures by 23.08%, particularly for more affluent households. With the implementation of NHI, lower and middle income quintiles had smaller decreases in out-of-pocket medical expenditure. NHI was also found to have reduced household out-of-pocket medical expenditures more for households in eastern Taiwan. CONCLUSION: Although NHI was established to create free medical care for all, further effort is needed to reduce the medical costs for certain disadvantaged groups, particularly the poor and aborigines, if equality is to be achieved.

Physical activity, cardiovascular disease, and medical expenditures in U.S. adults.

BACKGROUND: Physical inactivity is an established independent risk factor for cardiovascular disease (CVD), the leading cause of death and disability among U.S. adults. Information on the economic impact of CVD associated with inactivity is lacking, however, although it is needed to attract more resources for preventing CVD and promoting physical activity. PURPOSE: The objective of this study was to estimate the direct medical expenditures of CVD associated with inactivity. METHODS: A population-based analysis of direct medical expenditure was performed by linking the 1996 Medical Expenditure Panel Survey to the 1995 National Health Interview Survey. The study participants were adults (N = 2,472; ages > or = 19 years; not pregnant) in the noninstitutionalized, civilian population in 1996. Medical expenditures associated with inactivity were derived by comparing the medical expenditures between population groups stratified by physical activity and CVD status. RESULTS: In 1996, the prevalence of physical inactivity was 47.5%. The overall prevalence of CVD was 21.5% (16.7% in active persons, 23.6% in inactive persons, and 49.5% in persons with physical limitations). In this population, there were 7.3 million CVD cases. 1.1 million of them (15.3%) were associated with inactivity. The total medical expenditure of persons with CVD was US 41.3 billion dollars, of which US 5.4 billion dollars (13.1%) was associated with inactivity. Applying these percentages to the total health and economic burdens of CVD in the United States, there were 9.2 million CVD cases (US 23 .7 billion dollars direct medical expenditure) associated with inactivity in 2001. CONCLUSIONS: The high economic burden of inactivity-associated CVD demonstrates the need to promote physical activity among U.S. adults.

Prevalence, expenditures, utilization, and payment for persons with MS in insured populations.

OBJECTIVE: To determine the prevalence, expenditures, and utilization of enrollees with MS relative to all enrollees in privately insured, Medicare, and Medicaid populations. METHODS: The authors used insurer administrative billing data to identify persons with MS, their insured medical expenditures and utilization, and benchmark general insured population expenditures and utilization. Three samples of insurer billing data were analyzed: nationally representative samples for the privately insured (1994 through 1995) and Medicare (1996 though 1997) populations, and Medicaid data for disabled (1991 through 1996) populations from six states. RESULTS: Using 2 years of diagnoses on claims, the prevalence of MS in the privately insured population was 24 per 10,000, 36 per 10,000 in the Medicare population, and 71 per 10,000 in the Medicaid disabled population. Annual insured expenditures were $7,677 per privately insured enrollee with MS vs $2,394 for all privately insured enrollees, $13,048 per Medicare beneficiary with MS compared with $6,006 for all Medicare beneficiaries, and $7,352 per Medicaid disabled recipient with MS vs $4,088 per disabled recipient without MS. Home health expenditures were very high for Medicare beneficiaries with MS and nursing facility expenditures were very high for Medicaid disabled recipients with MS. A small proportion of enrollees with MS accounted for most expenditures. CONCLUSIONS: Insured enrollees with MS are two to three times more expensive than average insured enrollees. If the premiums that employers or governments pay health insurers and the capitation amounts that insurers pay health care providers do not account for these higher costs, a disincentive is created for the enrollment and care of persons with MS.

Health care for children and youth in the United States: 2001 annual report on access, utilization, quality, and expenditures.

OBJECTIVES: To provide an update on insurance coverage, use of health care services, and health expenditures for children and youth in the United States and new information on parents' perceived quality of care for their children and to provide information on variation in hospitalizations for children from a 24-state hospital discharge data source. METHODS: The data on insurance coverage, utilization, expenditures, and perceived quality of care come from the Medical Expenditure Panel Survey. The data on hospitalizations come from the Nationwide Inpatient Sample, which is part of the Healthcare Cost and Utilization Project. Both data sets are maintained by the Agency for Healthcare Research and Quality. RESULTS: In 2000, 64.5% of children were privately insured, 21.6% were insured through public sources, and 13.9% were uninsured. Children aged 15-17 years were more likely to be uninsured than children 1-4 years old. Children without health insurance coverage were less likely to use health care services, and when they did, their rates of utilization and expenditures were lower than insured children. Publicly insured children were the most likely to use hospital inpatient and emergency department (ED) care. Being black or Hispanic and living in families with incomes below 200% of the poverty line were associated with lower utilization and expenditures. A small proportion of children account for the bulk of health care expenditures: approximately 80% of all children's health care expenditures are attributable to 20% of children who used medical services. Although most parents report that their experiences with health care for their children are good, there are significant variations by type of insurance coverage. There are substantial differences in average length of hospitalization across the United States, ranging from 2.9-4.1 days, and rates of hospital admission through the ED, which vary across states from 10%-25%. Injuries are a major reason for hospitalization, accounting for 1 in 6 hospital stays among 10- to 14-year-olds. In the 10- to 17-year age group, more than 1 in 7 hospital stays are due to mental disorders. Among 15- to 17-year-olds, more than one third of all hospital stays are related to childbirth and pregnancy. The top 10 most common conditions treated in the hospital account for 40%-60% of all hospital stays. CONCLUSION: Children's use of health care services varies considerably by the type of health insurance coverage, race/ethnicity, and family income. Quality of care, as measured by parents' experiences of care, also varies by type of coverage. There is substantial variation in use of hospital services across states.

Health care for children and youth in the United States: 2002 report on trends in access, utilization, quality, and expenditures.

OBJECTIVE: To examine changes in insurance coverage, health care utilization, perceived quality of care, and expenditures for children and youth in the United States using data from 1987-2001. METHODS: Three national health care databases serve as the sources of data for this report. The Medical Expenditure Panel Survey (1996-2001) provides data on insurance coverage, utilization, expenditures, and perceived quality of care. The National Medical Expenditure Survey (1987) provides additional data on utilization and expenditures. The Nationwide Inpatient Sample (1995-2000) from the Healthcare Cost and Utilization Project provides information on hospitalizations. RESULTS: The percent of children uninsured for an entire year declined from 10.4% in 1996 to 7.7% in 1999. Most changes in children's health care occurred between 1987 and the late 1990s. Overall utilization of hospital-based services has declined significantly since 1987, especially for inpatient hospitalization. Several of the observed changes from 1987 varied significantly by type of health insurance coverage, poverty status, and geographic region. Quality of care data indicate some improvement between 2000 and 2001, which varies by insurance coverage. Overall, mean length of stay of hospitalizations did not change significantly from 1995 to 2000, but changes in the prevalence of hospitalizations and the length of stay associated with age-specific diagnoses were evident during this time period. CONCLUSIONS: Health care for children and youth has changed significantly since 1987, with most of the changes occurring between 1987 and 1996. Insurance coverage has improved, the site of care has shifted toward ambulatory sites, hospital utilization has declined, and expenditures on children as a proportion of total expenditures have decreased. Variation in these changes is evident by insurance status, poverty, and region.

Changing prescribing patterns and increasing prescription expenditures in Medicaid.

PURPOSE: Prescription drug expenditures are the most rapidly growing component of total health care expenditures and particularly affect state Medicaid programs. We determined the extent to which increasing prescription price and changing prescribing patterns contribute to rising prescription expenditures in Medicaid. METHODS: We conducted a claims-based analysis comparing annual prescription drug expenditures and prescribing patterns. Prescription drug and outpatient visit claims for all North Carolina Medicaid enrollees from 1998 through 2000 were included. We analyzed drugs individually by combining all prescriptions and expenditures for the same drug formulation, and we calculated the number of units dispensed per person-year of enrollment. RESULTS: Prescription drug coverage for 1 person-year cost 503 dollars in 1998 and 759 dollars in 2000, for an annual increase of 22.8%. The average number of prescriptions filled per person-year increased from 13.0 in 1998 to 15.5 in 2000. Increased prescribing for 6 drugs accounted for more than 25% of the total increase in expenditures. The price for the 15 most expensive drugs increased an average of 4.1% annually. CONCLUSIONS: Prices for existing drugs increased slightly during the study period, but the major cause of the increase in drug costs was an increase in the number of prescriptions for new and more expensive medications. Prescribing patterns in Medicaid differ somewhat from those in the private sector and partly reflect the population with low socioeconomic status and high health care needs that it serves. To help control rising prescription drug expenditures, efforts should be undertaken to improve appropriate and cost-effective prescribing.

Does gatekeeping control costs for privately insured children? Findings from the 1996 medical expenditure panel survey.

OBJECTIVE: Gatekeeping requirements were widely adopted by health insurers in an attempt to control costs in the mid-1990s, but empirical evidence demonstrating decreased health expenditures for children enrolled in such plans is lacking. METHODS: We analyzed data from 3254 children with private health insurance sampled in the 1996 Medical Expenditure Panel Survey (MEPS) to compare total per capita health expenditures among gatekeeping versus indemnity plan enrollees. This sample represents 40.4 million privately insured American children. Total expenditures were defined as payments from all sources, including third-party and out-of-pocket payments, but excluding administrative costs. MEPS data are based on information provided by patients, health care providers, and hospitals. Gatekeeping plans included all children enrolled in health maintenance organizations or other plans requiring a primary care gatekeeper. All others were considered indemnity plan enrollees. RESULTS: Mean total per capita annual expenditures for children in gatekeeping versus indemnity plans differed by <1% (887 dollars vs 881 dollars, respectively). Third-party payments by gatekeeping plans on behalf of their beneficiaries were 636 dollars versus 595 dollars by indemnity plans. Out-of-pocket payments were on average 62 dollars less for gatekeeping enrollees than for indemnity enrollees. After multivariate adjustment, mean per capita expenditures were approximately 4% lower for gatekeeping enrollees than for indemnity enrollees. CONCLUSION: In 1996, total per capita annual health expenditures for children in gatekeeping plans were approximately 8 dollars less than for those in indemnity plans. These data indicate that gatekeeping is not an effective cost-containment method for children.

Health care expenditures associated with overweight and obesity among US adults: importance of age and race.

OBJECTIVES: We estimated health care expenditures associated with overweight and obesity and examined the influence of age, race, and gender. METHODS: Using 1998 Medical Expenditure Panel Survey data, we employed 2-stage modeling to estimate annual health care expenditures associated with high body mass index (BMI) and examine interactions between demographic factors and BMI. RESULTS: Overall, the mean per capita annual health care expenditure (converted to December 2003 dollars) was $3338 before adjustment. While the adjusted expenditure was $2127 (90% confidence interval [CI]=$1927, $2362) for a typical normal-weight White woman aged 35 to 44 years, expenditures were $2358 (90% CI=$2128, $2604) for women with BMIs of 25 to 29.9 kg/m(2), $2873 (90% CI=$2530, $3236) for women with BMIs of 30 to 34.9 kg/m(2), $3058 (90% CI=$2529, $3630) for women with BMIs of 35 to 39.9 kg/m(2), and $3506 (90% CI=$2912, $4228) for women with BMIs of 40 kg/m(2) or higher. Expenditures related to higher BMI rose dramatically among White and older adults but not among Blacks or those younger than 35 years. We found no interaction between BMI and gender. CONCLUSIONS: Health care costs associated with overweight and obesity are substantial and vary according to race and age.

State health care expenditures under competition and regulation, 1980 through 1991.

OBJECTIVES: This paper examines health expenditure growth under two alternative policy approaches: competition-based managed care and state government rate regulation. METHODS: Data are presented on cumulative growth in real per capita health expenditures between 1980 and 1991 so as to compare California, a state with a pro-competitive policy, with the US average and with four states with established regulation programs. RESULTS: Real per capita expenditures for hospital services in the United States grew 54% between 1980 and 1991, while in California the growth was half the national rate, or 27%. Real per capita expenditures for physician services and drug expenditures in the United States grew by 82% and 65%, respectively, while in California these expenditures increased only 58% and 41%, respectively. California's growth rate was below that of all four regulatory states for all measures of health care cost inflation. CONCLUSIONS: On the basis of these findings, a properly structured competitive approach could play a significant role in controlling health expenditures in the United States.
