Subjective social status predicts smoking abstinence among light smokers.

Objectives: To determine if community subjective social status (SSS) predicted smoking abstinence through 26 weeks postrandomization among 755 African American light smokers of low SES (socioeconomic status).

Methods: Participants were enrolled in a double-blind, placebo-controlled, randomized clinical trial, which examined the efficacy of nicotine gum and counseling for smoking cessation.

Results: Results indicated that SSS predicted smoking abstinence over time [P=.

Analysis of femoral artery intima-media thickness during the cardiac cycle.

Background: Variations in the intima-media thickness (IMT) of the carotid artery during the cardiac cycle are well established. The change in femoral IMT during the cardiac cycle is largely unknown. This study focuses on the variation of femoral IMT, vessel diameter, and cross-sectional area (CSA) of the IMT during the cardiac cycle.
