Although not sufficient to produce weight loss, the combination of web intervention and group sessions with telephone follow-up yielded improvements in sedentary behavior and in the use of behavior change strategies expected to lead to behavior change.

Purpose To describe the theoretical rationale, intervention design, and clinical trial of a two-year weight control intervention for young adults deployed via social and mobile media. Methods A total of 404 overweight or obese college students from three Southern California universities (Mage = 22(±4) years; MBMI=29(±2.8); 70% female) were randomized to participate in the intervention or to receive an informational web-based weight loss program. The intervention is based on behavioral theory and integrates intervention elements across multiple touch points, including Facebook, SMS, smartphone applications, blogs, and e-mail. Participants are encouraged to seek social support among their friends, self-monitor their weight weekly, post their health behaviors on Facebook, and e-mail their weight loss questions/concerns to a health coach. The intervention is adaptive because new theory-driven and iteratively tailored intervention elements are developed and released over the course of the two-year intervention in response to patterns of use and user feedback. Measures of body mass index, waist circumference, physical activity (PA), sedentary behavior (SED), diet, weight management practices, smoking, alcohol, sleep, body image, self-esteem, and depression occur at 6, 12, 18, and 24 months. Currently, all participants have been recruited, and all are in the final year of the trial. Conclusion Theory-driven, evidence-based strategies for PA, SED, and dietary intake can be embedded in an intervention using social and mobile technologies to promote healthy weight-related behaviors in young adults.

Objective-To evaluate the association between secondhand smoke (SHS) exposure and depression. Tobacco smoking and depression are strongly associated, but the possible effects of SHS have not been evaluated. Results-Serum cotinine-documented SHS exposure was positively associated with depressive symptoms in never-smokers, even after adjustment for age, race/ethnicity, gender, education, alcohol consumption, and medical comorbidities. The association between SHS exposure and depressive symptoms did not vary by gender, nor was there any association between SHS smoke exposure and depressive symptoms in former smokers. Methods-TheConclusions-Findings from the present study suggest that SHS exposure is positively associated with depressive symptoms in never-smokers and highlight the need for further research to establish the mechanisms of association.

Because intensifying and increasing cyclophosphamide two or four times that given in standard clinical practice did not substantively improve outcome, such therapy should be reserved for the clinical trial setting.

OBJECTIVEDifferences in the prevalence of cardiovascular disease (CVD) and its risk factors among occupational groups have been found in several studies. Certain types of workers (such as shift workers) may have a greater risk for metabolic syndrome, a precursor of CVD. The objective of this study was to assess the differences in prevalence and risk of metabolic syndrome among occupational groups using nationally representative data of U.S. workers.RESEARCH DESIGN AND METHODSData from 8,457 employed participants (representing 131 million U.S. adults) of the 1999–2004 National Health and Nutrition Examination Survey were used. Unadjusted and age-adjusted prevalence and simple and multiple logistic regression analyses were conducted, adjusting for several potential confounders (BMI, alcohol drinking, smoking, physical activity, and sociodemographic characteristics) and survey design.RESULTSOf the workers, 20% met the criteria for the metabolic syndrome, with “miscellaneous food preparation and food service workers” and “farm operators, managers, and supervisors” having the greatest age-adjusted prevalence (29.6–31.1%) and “writers, artists, entertainers, and athletes,” and “engineers, architects, scientists” the lowest (8.5–9.2%). In logistic regression analyses “transportation/material moving” workers had significantly greater odds of meeting the criteria for metabolic syndrome relative to “executive, administrative, managerial” professionals (odds ratio 1.70 [95% CI 1.49–2.52]).CONCLUSIONSThere is variability in the prevalence of metabolic syndrome by occupational status, with “transportation/material moving” workers at greatest risk for metabolic syndrome. Workplace health promotion programs addressing risk factors for metabolic syndrome that target workers in occupations with the greatest odds may be an efficient way to reach at-risk populations.

People with chronic disease generally reported better nutrition awareness and food label use and checking behaviors compared with those without chronic disease, but this did not translate into unequivocally better eating behaviors. New strategies are needed to improve the actual nutritional behaviors of persons with chronic disease.

When administered as a continuous 24-hour infusion, high-dose paclitaxel results in a higher tumor response rate than when administered as a 3-hour infusion but does not significantly improve event-free survival or survival. Paclitaxel as a 24-hour infusion results in increased hematologic toxicity and decreased neurosensory toxicity.

Background-Hearing loss has been associated with tobacco smoking, but its relationship with secondhand smoke is not known. We sought to investigate the association between secondhand smoke exposure and hearing loss in a nationally representative sample of adults.
