Initial engagement and attrition in a national weight management program: demographic and health predictors.

Inconsistent attendance and participant withdrawal limit the effectiveness of weight control programs, but little is known about predictors of initial and ongoing engagement. The purpose of this study was to identify these predictors with respect to the Veterans Affairs MOVE!® program, using medical record data. Logistic regression models were used to predict initial and ongoing engagement (n = 39,862 and 1985, respectively). Those who initially engaged in MOVE!® (vs. did not) were more likely to have high BMIs, to be female, live closer to the medical center, and receive health benefits from the VA; they also were less likely to use tobacco (ps < 0.02). Older veterans were more likely to continue to engage (p < 0.001), with trends toward continued engagement for those with (vs. without) benefits and higher BMIs (ps < 0.10). Findings highlight characteristics that may inform program improvements that promote ongoing engagement and prevent dropouts in a weight management programs.

Body mass index and depressive symptoms in primary care settings: examining the moderating roles of smoking status, alcohol consumption and vigorous exercise.

WHAT IS ALREADY KNOWN ABOUT THIS SUBJECT: Depressive symptoms and obesity are highly prevalent in primary care settings. Depressive symptoms and obesity are positively related; as body weight increases, individuals are more likely to display depressive symptoms. WHAT THIS STUDY ADDS: This study examines the moderating roles of health behaviours (alcohol use, smoking status and vigorous exercise) on the relationship between body mass index and depressive symptoms. Exercise attenuates the relationship between depressive symptoms and obesity. Primary care patients often report multiple health risk behaviours and symptoms, including obesity and depressive symptomatology. This study examined the relationship between body mass index (BMI) and depressive symptomatology among primary care patients and tested its moderation by health behaviours. Primary care patients (n = 497) completed self-report questionnaires. Using three multilevel models, we tested the moderation of health behaviours on the BMI-depressive symptoms relationship. After controlling for relevant covariates, BMI was positively related to depressive symptoms. Smokers reported more depressive symptoms (P < 0.01), whereas vigorous exercisers reported fewer (P < 0.001). Alcohol consumption was not related to depressive symptoms (P > 0.05). Only vigorous exercise significantly moderated the BMI-depression relationship (P < 0.05). BMI is positively related to depressive symptoms among patients who do not participate in vigorous activity, suggesting that vigorous activity reduces the risk for depressive symptoms among patients with higher BMI.

Behavioral activation and problem-solving therapy for depressed breast cancer patients: preliminary support for decreased suicidal ideation.

Major depressive disorder (MDD) is the most common psychiatric disorder in breast cancer patients. The prevalence of suicidal ideation in breast cancer patients is considerable, and relative to the general population, the prevalence of completed suicide is elevated, particularly in cancer patients with MDD. A major component of suicide prevention is effective treatment of MDD. Although some research has explored the utility of psychotherapy with breast cancer patients, only three trials have explored the benefits of behavior therapy in patients with well-diagnosed MDD and there has been no systematic investigation of the potential benefits of psychotherapy toward reducing suicidal ideation in breast cancer patients. As a follow-up to a recently completed randomized trial, this study examined the efficacy of 8 weeks of behavioral activation treatment for depression (BATD) and problem-solving therapy (PST) in reducing depression and suicidal ideation, as well as increasing hopefulness in breast cancer patients with MDD (n = 80). Across both treatments, GEE analyses revealed decreased depression and suicidal ideation and increased hopefulness at posttreatment, results that were maintained at 12-month follow-up. Moreover, follow-up patient contact at approximately 2 years posttreatment yielded no indication of completed suicide. Although these data are preliminary, BATD and PST may represent practical approaches to decrease suicidal ideation in depressed breast cancer patients.
