IMPORTANCE Accumulating evidence suggests that bariatric surgery improves survival among patients with severe obesity, but research among veterans has shown no evidence of benefit. OBJECTIVE To examine long-term survival in a large multisite cohort of patients who underwent bariatric surgery compared with matched control patients. DESIGN, SETTING, AND(More)
We examined prevalence and predictors of trauma among HIV-infected persons in the Deep South using data from the Coping with HIV/AIDS in the Southeast (CHASE) study. Over 50% of CHASE participants were abused during their lives, with approximately 30% experiencing abuse before age 13, regardless of gender. Caregiver characteristics were associated with(More)
BACKGROUND AND OBJECTIVES Early detection of CKD is important for slowing progression to renal failure and preventing cardiovascular events. Automated laboratory reporting of estimated GFR (eGFR) has been introduced in many health systems to improve CKD recognition, but its effect in large, United States-based health systems remains unclear. DESIGN,(More)
Importance Bariatric surgery induces significant weight loss for severely obese patients, but there is limited evidence of the durability of weight loss compared with nonsurgical matches and across bariatric procedures. Objectives To examine 10-year weight change in a large, multisite, clinical cohort of veterans who underwent Roux-en-Y gastric bypass(More)
OBJECTIVES To analyze the effect of smoking, smoking cessation, and other modifiable risk factors on mobility in middle-aged and older Americans. DESIGN Panel study; secondary data analysis. SETTING United States (national sample). PARTICIPANTS The Health and Retirement Study (HRS) includes data on 12,652 Americans aged 50 to 61 in four waves(More)
BACKGROUND Behavioral weight-loss treatment can improve health, yet it is underutilized. Factors leading to initiation of weight-loss treatment are not well characterized. In particular, it is unknown whether changes in obesity-related health status contribute to weight-loss treatment initiation. PURPOSE To determine if recent weight change or diagnosis(More)
PURPOSE With ethical requirements to the enrollment of lower risk subjects, osteoporosis trials are underpowered to detect reduction in hip fractures. Different skeletal sites have different levels of fracture risk and response to treatment. We sought to identify fracture sites which cluster with hip fracture at higher than expected frequency; if these(More)
BACKGROUND Influenza is a common and serious public health problem among the elderly. The influenza vaccine is safe and effective. METHODS The purpose of the study was to determine whether frequencies of receipt vary by race, age group, gender, and time (progress from 1995/1996 to 2000), and whether any racial differences remain in age groups covered by(More)
OBJECTIVE To determine whether health insurance expansions via a Medicare buy-in might plausibly increase mammography screening rates among women aged 50-64. DATA SOURCES Two waves of the Health and Retirement Study (HRS) (1994, 1996). STUDY DESIGN A longitudinal study with most explanatory variables measured at the second wave of HRS (1994); receipt of(More)
