Traditional methods for determining crash responsibility – most commonly moving violation citations – may not accurately characterize at-fault status among crash-involved drivers given that: (1) issuance may vary by factors that are independent of fault (e.g., driver age, gender), and (2) these methods do not capture driver behaviors that are not illegal but still indicative… Continue reading Statistical implications of using moving violations to determine crash responsibility in young driver crashes

Validation of a polysomnographic score for REM sleep behavior disorder
STUDY OBJECTIVES: Rapid eye movement (REM) sleep behavior disorder (RBD) was described more than 2 decades ago, but only 1 report on 5 patients and 5 normal subjects has tested the effectiveness of a method by which relevant polysomnographic findings can be quantified. We sought to validate this method in a larger sample of patients… Continue reading Validation of a polysomnographic score for REM sleep behavior disorder
Diabetes-related change in physical disability from midlife to older adulthood: evidence from 1996-2003 Survey of Health and Living Status of the Elderly in Taiwan
One in five older adults in Taiwan have been diagnosed with diabetes. This study drew on disability data for 5121 nationally representative middle-aged and older adults from the 1996-2003 Survey of Health and Living Status of the Elderly in Taiwan (SHLSET). By employing cohort sequential design and multilevel models, it combined cross-sectional and longitudinal evidence… Continue reading Diabetes-related change in physical disability from midlife to older adulthood: evidence from 1996-2003 Survey of Health and Living Status of the Elderly in Taiwan
Racial differences in disability after stroke: results from a nationwide study
OBJECTIVE: We sought to characterize racial differences in disability among older stroke survivors. METHODS: A cross-sectional study of 806 self-reported stroke survivors from the 2011 National Health and Aging Trends Study was performed. Race was based on self-report. Primary outcome was activity limitations (requiring assistance with mobility, self-care, and household activities). Secondary outcome was participation… Continue reading Racial differences in disability after stroke: results from a nationwide study
Associations among cataract prevalence, sunlight hours, and altitude in the Himalayas
The relationship between cataract prevalence, altitude, and sunlight hours was investigated in a large national probability sample survey of 105 sites in the Himalayan kingdom of Nepal, December 1980 through April 1981. Cataract of senile or unknown etiology was diagnosed by ophthalmologists in 873 of 30,565 full-time life-long residents of survey sites. Simultaneously, the altitude… Continue reading Associations among cataract prevalence, sunlight hours, and altitude in the Himalayas
Clinical complexity in middle-aged and older adults with diabetes: The health and retirement study
Background: Some patients with diabetes may have health status characteristics that could make diabetes self-management (DSM) difficult and lead to inadequate glycemic control, or limit the benefit of some diabetes management interventions. Objective: To investigate how many older and middle-aged adults with diabetes have such health status characteristics. Design: Secondary data analysis of a nationally… Continue reading Clinical complexity in middle-aged and older adults with diabetes: The health and retirement study
