BACKGROUND Health risks linked to obesity and the difficulty most have in achieving weight loss underscore the importance of identifying dietary factors that contribute to successful weight loss. METHODS This study examined the association between change in dietary energy density and weight loss over time. Subjects were 213 men and women with BMI of 30-39(More)
Using data from smokers (N = 591) who enrolled in an 8-week smoking cessation program and were then followed for 15 months, the authors tested the thesis that self-efficacy guides the decision to initiate smoking cessation but that satisfaction with the outcomes afforded by quitting guides the decision to maintain cessation. Measures of self-efficacy and(More)
This paper examines the relationships among reports of depressive symptoms, BMI and frequency of consumption of 30 foods in 4655 middle-aged women. Food was grouped into three categories: high-calorie sweet, high-calorie nonsweet, and low-calorie. Controlling for total energy intake, BMI and depressive symptoms were both inversely associated with a higher(More)
This study examines the hypothesis that highly favorable outcome expectations promote weight loss and hinder weight maintenance. To investigate the effects of outcome expectations and satisfaction with treatment outcomes on weight loss, 349 adults were randomly assigned to 1 of 2 weight loss programs that emphasize either (a) an "optimistic" message,(More)
OBJECTIVE Evaluate the association between obesity and depression among middle-aged women. METHODS A total of 4641 female health plan enrollees aged 40-65 years completed a structured telephone interview including self-reported height and weight, the Patient Health Questionnaire (PHQ) assessment of depression; a brief measure of rate was 62%. RESULTS(More)
OBJECTIVE We evaluated whether participation in a community-based group diabetes prevention program might lead to relative changes in composite 10-year coronary heart disease (CHD) risk for overweight adults with abnormal glucose metabolism. RESEARCH DESIGN AND METHODS We used the UK Prospective Diabetes Study engine to estimate CHD risk for(More)
OBJECTIVE Our primary objective was to test the thesis that the initiation of behavior change is dependent on favorable expectations, whereas maintaining a change in behavior is dependent on satisfaction with the outcomes afforded by behavior change. These hypotheses were tested in the context of a smoking cessation intervention. DESIGN Adult smokers were(More)
SUMMARY Data from a trial of a 26-session structured group behavioral weight loss intervention were used to examine how group attendance, weight loss, and changes in depression clustered within therapy groups. Participants were recruited via a population-based survey of female health plan members aged 40-65. The sample included 143 women attending 13(More)
Objective. Weight loss is the most effective approach to reducing diabetes risk. It is a research priority to identify factors that may enhance weight loss success, particularly among those at risk for diabetes. This analysis explored the relationships between self-efficacy, weight loss, and dietary fat intake among adults at risk for developing type 2(More)
