PURPOSE: Residing in deprived areas may increase risk of mortality beyond that explained by a person's own SES-related factors and lifestyle. The aim of this study was to examine the relation between neighborhood socioeconomic deprivation and all-cause, cancer- and cardiovascular disease (CVD)-specific mortality for men and women after accounting for education and other important person-level risk factors. METHODS: In the longitudinal NIH-AARP Study, we analyzed data from healthy participants, ages 50-71 years at study baseline (1995-1996). Deaths (n = 33831) were identified through December 2005. Information on census tracts was obtained from the 2000 US Census. Cox models estimated hazard …

BACKGROUND: Colonoscopy may be less efficacious in reducing colorectal cancer mortality in the proximal compared with the distal colon. A greater likelihood for missed and recurrent adenomas in the proximal colon may contribute to this phenomenon.

OBJECTIVE: To examine whether a proximal adenoma is associated with the risk and location of missed and recurrent adenomas.

DESIGN: Prospective.

SETTING: Polyp Prevention Trial.

PARTICIPANTS: A total of 1864 patients with an adenoma at baseline underwent a follow-up colonoscopy 4 years later (adenoma recurrence). Of these, 1731 underwent a clearing colonoscopy 1 year after the baseline examination (missed adenoma).

MAIN OUTCOME MEASUREMENTS: Association …
