Associations of lifetime cumulative estrogen exposure with lifecourse social exposures, cognitive decline, and dementia risk among postmenopausal White, Black, and Latina women
Cumulative estrogen exposure is socially patterned. We found that lifecourse social factors and estrogen exposure synergistically contribute to women's late-life cognitive health outcomes. Understanding how sex-linked biology and gender-related social forces intertwine is essential for developing interventions to decrease dementia risk among women
Mediators of educational differences in dementia risk later in life
Despite a well-known inverse association between education and dementia risk, the mediating mechanisms are not well understood. We explored how lifestyle and health risk factors across the life-course mediate the relationship between education and dementia among adults aged 70 + years. We included 7,655 participants with dementia diagnoses and education information, using a historical cohort design linking prospective exposure data across the lif…
Number of children and risk of dementia
BACKGROUND: Findings on the link between the number of children and dementia risk are inconsistent, mostly studied in females, suggesting pregnancy-related changes may be a key factor in this association. METHODS: The Adult Changes in Thought Study is a cohort of adults aged ≥65 years from Kaiser Permanente Washington. The primary exposure was the number of children (0, 1, 2, 3 or ≥4), and the outcome was an incident dementia diagnosis. Cox propo…
Marital Histories and Associations With Later-Life Dementia and Mild Cognitive Impairment Risk in the Hunt4 70+ Study in Norway
Objectives: Earlier studies suggest that being married in later life protects against dementia, and that being single in old age increases the risk of dementia. In this study, we examine midlife marital status trajectories and their association with dementia and mild cognitive impairment (MCI) at ages 70 plus using a large population based sample from Norway. Methods: Based on a general population sample linked to population registries ( N = 8706…
Continuity of Care and Mental Health Service Use Among Medicaid-enrolled Youths
BACKGROUND: Recent reports of increased national estimates of pediatric psychiatric emergency department (ED) visits and psychiatric hospitalizations emphasize the need to research these utilization patterns. OBJECTIVES: To assess the patient-provider continuity of care (CoC) and compare the risk of psychiatric ED visits or hospitalization according to the CoC level. RESEARCH DESIGN: A cohort design was applied to Medicaid administrative claims d…
Utilization of Screening Mammograms in the Medicare Population Before and After the Affordable Care Act Implementation
Objective: This study examined screening mammograms in women aged 65 to 74 years and 75+ years before and after the Affordable Care Act (ACA) implementation. Method: This repeated cross-sectional study of community-dwelling women age 65+ years without a history of breast cancer or mastectomy utilized the Medicare Current Beneficiary Survey and Medicare fee-for-service claims data from 2001 to 2013. We used covariate-adjusted logistic regression w…
Quantifying the Cost of Disability Transitions in Medicare
Interventions aimed at preventing disability progression and efforts to restore functional capacity are promising strategies for containing costs and generating savings for Medicare. Future research is needed to assess the longer term impact of disability in association with the progression of chronic conditions
Characterization of Dementia and Alzheimer’s Disease in an Older Population
Objectives. We estimated dementia incidence rates, life expectancies with and without dementia, and percentage of total life expectancy without dementia. Methods. We studied 3605 members of Group Health (Seattle, WA) aged 65 years or older who did not have dementia at enrollment to the Adult Changes in Thought study between 1994 and 2008. We estimated incidence rates of Alzheimer’s disease and dementia, as well as life expectancies with and witho…
Health Care Spending and Utilization by Race/Ethnicity Under the Affordable Care Act’s Dependent Coverage Expansion
Objectives. We estimated the effect of the ACA expansion of dependents’ coverage on health care expenditures and utilization for young adults by race/ethnicity. Methods. We used difference-in-difference models to estimate the impact of the ACA expansion on health care expenditures, out-of-pocket payments (OOP) as a share of total health care expenditure, and utilization among young adults aged 19 to 26 years by race/ethnicity (White, African Amer…
Associations Between Poor Sleep Quality and Psychosocial Stress with Obesity in Reproductive-age Women of Lower Socioeconomic Status
An Introduction to Macro-Level Spatial Nonstationarity
Type II diabetes is a growing health problem in the United States. Understanding geographic variation in diabetes prevalence will inform where resources for management and prevention should be allocated. Investigations of the correlates of diabetes prevalence have largely ignored how spatial nonstationarity might play a role in the macro-level distribution of diabetes. This paper introduces the reader to the concept of spatial nonstationarity-var…
Patterns in trouble sleeping among women at mid-life
BACKGROUND: Although trouble sleeping is a common problem among women at mid-life, patterns in trouble sleeping relating to social and health-related risk factors are unclear. This analysis describes the dynamics of trouble sleeping among women at mid-life. METHODS: The National Survey of Health and Development is a nationally representative study of births in 1946 in England, Scotland, and Wales followed up through mid-life. Multistate life tabl…
