Evolution of the US nonmetropolitan mortality disadvantage by sex, state, and year, 1999‐2019
PURPOSE: To examine disparities in nonmetropolitan and metropolitan mortality by state and sex from 1999 to 2019. METHODS: We calculate age-standardized mortality rates for nonmetropolitan and metropolitan areas by state and sex and compute age-standardized differences in these rates within each state and relative to the national average. We further estimate the number of excess deaths in nonmetropolitan areas by state. These are deaths that woul…
Trends in Obesity Care Among US Adults, 2010–2021
BACKGROUND: Obesity is a major contributor to mortality in the United States. Clinical guidelines emphasize the need for multimodal treatment, but novel treatments may be changing care-seeking behavior. OBJECTIVE: To characterize obesity treatment access patterns and factors associated with obesity care from 2010 to 2021 in the United States. RESEARCH DESIGN: This multiyear cross-sectional study was conducted using Medical Expenditure Panel Surve…
Affordable Health Insurance Options for Small Business and Low-Wage Workers Remains Elusive
Low-wage workers and those employed by small businesses are least likely to be offered health insurance coverage and they are over-represented among the uninsured. Two new forms of health reimbursement arrangements (HRAs) that allow employers to help fund individual market coverage for workers have been touted as breakthrough strategies to help fill this gap. Despite several years of experience and low adoption, little is known about employer und…
Covid-19 and All-Cause Mortality by Race, Ethnicity, and Age Across Five Periods of the Pandemic in the United States
Racial/ethnic and age disparities in COVID-19 and all-cause mortality during 2020 are well documented, but less is known about their evolution over time. We examine changes in age-specific mortality across five pandemic periods in the United States from March 2020 to December 2022 among four racial/ethnic groups (non-Hispanic White, non-Hispanic Black, Hispanic, and non-Hispanic Asian) for ages 35+. We fit Gompertz models to all-cause and COVID-1…
The role of context in shaping the relationship between physical health and suicide over the life course
U.S. suicide rates are at a thirty-year high while physical health, as measured by life expectancy and pain, has declined, particularly for those without a college degree. We investigate how these patterns may be related by exploring the role of physical health problems in suicide deaths using 2019 data from the National Violent Death Reporting System. We estimate multilevel logistic regression models to examine (1) how individual risk factors ar…
Increases in BMI and chronic pain for US adults in midlife, 1992 to 2016
Recent unprecedented increases in mortality and morbidity during midlife are often ascribed to rising despair in the US population. An alternative and less often examined explanation is that these trends reflect, at least in part, the lagged effects of the obesity epidemic. Adults in midlife today are more likely to live with obesity and have a greater cumulative exposure to excess adiposity during their lifetime than any previous generation. Pri…
The Secret Menu in Health Care
In addition to the prices they negotiate with private health insurers, most providers also have a cash price schedule for patients who have the wherewithal to ask and are willing to pay in full when they receive a service. This is the first study that estimates the potential cost saving of allowing privately-insured consumers to observe both in-network negotiated prices and cash prices, which is of particular interest given the growing importance…
Practice Patterns of Physicians and Nurse Practitioners in Primary Care
BACKGROUND: Primary care practices increasingly include nurse practitioners (NPs), in addition to physicians. Little is known about how the patient mix and clinical activities of colocated physicians and NPs compare. OBJECTIVES: To describe the clinical activities of NPs, compared with physicians. RESEARCH DESIGN: We used claims and electronic health record data from athenahealth Inc., on primary care practices in 2017 and a cross-sectional analy…
Considerations for Measuring the Impact of Policy-Relevant Research
Philanthropy, and the research and analysis it supports, has an important role to play in informing policy and making government more effective. Yet all too often, foundations and other research funders struggle to understand whether and how their investments have affected policy. This article highlights the findings of an 18-month pilot project conducted by AcademyHealth to help the Robert Wood Johnson Foundation better understand the impact of …

The Fragmentation of Hospital Use Among a Cohort of High Utilizers
BACKGROUND: Use of multiple hospitals by patients with multiple chronic conditions (MCC) may undermine emerging care coordination initiatives. OBJECTIVE: The aim of this study was to assess the prevalence and correlates of fragmented hospital use among high users with MCC and derive implications for care management. RESEARCH DESIGN: Using all-payer hospital billing data, we follow a 2-year cohort of patients with at least 2 inpatient stays, ident…
Method Choice in Nonfatal Self-Harm as a Predictor of Subsequent Episodes of Self-Harm and Suicide
Objectives. We examined time-varying and time-invariant characteristics of nonfatal intentional self-harm episodes in relation to subsequent episodes of self-harm and suicide. Methods. We conducted a follow-up cohort study through 2007 of 3600 patients discharged from hospitals in New Jersey with a primary diagnosis of intentional self-harm in 2003. We determined repetition of self-harm from hospital records and suicide from state registers. Resu…
Mobility of the Foreign-Born Population in the United States, 1995–2000
This study uses the 2000 PUMS to examine mobility among the foreign-born population and the role of the gateway states. Between 1995 and 2000, net domestic migration of the foreign-born population to gateway states was negative. Yet the rate of out-migration from gateway states was lower than that from non-gateway states. Overall, the findings do not support the idea that gateway states are “losing their hold” on their foreign-born population. Ye…

Telecommuting and the Demand for Urban Living
With recent advances in communications technology, telecommuting appears to be an increasingly viable option for many workers. For urban researchers, the key question is whether this growing ability to telecommute is altering residential location decisions and leading households to live in smaller, lower-density and more remote locations. Using the Work Schedules supplement from the 1997 Current Population Study, this paper explores this question…
Immigration and Net Migration in New York City 1980–90
The relationship between immigration and the net migration of the native‐born is an important component of the overall impact of immigration. Prior analyses of cross‐sectional state and Metropolitan Statistical Area data suggest that a negative relationship exists, particularly among those with relatively little education. At the national level, much attention has been paid to the potential ethnic segregation of the population as primarily non‐Wh…
Contemporary American Attitudes toward U.S. Immigration
This article aims to contribute to an understanding of contemporary American attitudes toward immigration.... The paper uses data from a CBS News/New York Times poll conducted in June 1993. Respondents were asked whether they would like to see the level of immigration to the United States increased, decreased or kept the same. We test several hypotheses about factors influencing respondents' attitudes, including the importance of previously unexa…
Using surname data in U.S. Puerto Rican mortality analysis
Evidence suggests that among mainland-born decedents, Hispanic (particularly Puerto Rican) origin may have been underreported in states that have added an ancestry item to their death certificates. This study uses the 1980 Census Bureau Spanish-surname list to code surnames on New York City death certificates. By examining the correspondence between surname type and the response to the ancestry item, we identify potential underreporting of Hispan…
Mortality among Three Puerto Rican Populations
This study attempts to explain similarities and differences in the mortality experience of three population groups: Puerto Ricans on the island commonwealth, Puerto Rican born persons in New York City and Puerto Rican born persons in the rest of mainland United States. Mortality is much higher among Puerto Ricans in New York City than among those residing elsewhere. Much of the difference is due to excess mortality caused by cirrhosis of the live…

Differential mortality by ethnicity and nativity
This paper compares the mortality experience of foreign- and native-born Irish, Italians, and Jews in New York City in 1979-81. In most cases, denominator data were not available, so proportional mortality analysis was used. An estimation procedure was undertaken to show the degree to which standardized proportional mortality ratios approximate relative standardized mortality measures. Major and lifestyle-related causes of death were examined, as…
