An exercise training program may be considered an alternative to antidepressants for treatment of depression in older persons. Although antidepressants may facilitate a more rapid initial therapeutic response than exercise, after 16 weeks of treatment exercise was equally effective in reducing depression among patients with MDD.

Results show preliminary efficacy and acceptability of the two active intervention arms (97.0% found the program helpful, 81.3% found the videos/handouts helpful, and 100% would recommend the program to others). Results indicate the potential for an innovative weight loss intervention that uses technology platforms (Facebook and text messaging) that are frequently used and already integrated into the cultural life of college students.

The Internet has the potential for delivering innovative, interactive physical activity (PA) interventions to large numbers of people. This study was designed to test the efficacy of an Internet intervention that consisted of a Web site plus 12 weekly e-mail tip sheets, compared with a waiting list control group. The Internet intervention was theory based and emphasized clear, graphical presentation of PA information. Sixty-five (30 intervention and 35 control) sedentary adult employees of several large hospitals (9 men and 56 women) were randomly assigned to 1 of the 2 study arms. Of the 65 participants, 57 completed the 1-month follow-up, and 52 completed the 3-month follow-up. At both 1 and 3 months, those in the intervention group were significantly more likely to have progressed in stage of motivational readiness for PA than participants in the control group: 1 month, c2(1, N =52) =4.05, p <.05; 3 months, c2(1, N =52) =6.45, p <.01. We hypothesized that at 1 and 3 months, the intervention group would exhibit significant increases relative to the control group on the number of minutes of moderate activity. At the 1-month assessment, the intervention group did exhibit significant increases, relative to the control group in moderate minutes, F(1, 54) =5.79, p <.05; however, at the 3-month assessment this difference was no longer significant. In addition, secondary analyses were conducted to examine total number of minutes of walking reported. At 1 month, the intervention group did exhibit significant increases, relative to the control group, in walking minutes, F(1, 54) =12.1, p <.001. At the 3-month assessment, amount of time spent in walking activity continued to be significantly higher for the intervention group compared with the control group, F(1, 48) =5.2, p <.05. These findings show that a theoretically based PA Web site and weekly e-mail tip sheets can have a short-term impact on PA motivation and behavior both at 1 and 3 months. As Internet access increases, and as bandwidth and other technical attributes of this medium improve, Web site delivered health behavior interventions will become increasingly useful in public health promotion.

Results suggest that both telephone and print enhance the adoption of physical activity among sedentary adults; however, print interventions may be particularly effective in maintaining physical activity in the longer term.

Background: Physical activity interventions tailored to individual characteristics and delivered via print produce greater increases in activity compared with nontailored interventions and controls. Using the Internet to deliver a tailored physical activity intervention offers an alternative to print that might be available to larger populations at a lower cost. Methods: Participants (N = 249 adults; mean [SD] age, 44.5 [9.3] years; and mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 29.4 [6.1]) were randomized to 1 of 3 physical activity interventions: (1) motivationally tailored Internet (tailored Internet, n=81), (2) motivationally tailored print (tailored print, n=86); and (3) 6 researcher-selected Web sites available to the public (standard Internet, n=82). Participants in the tailored Internet and tailored print arms received the same tailored intervention content. Participants were assessed at baseline and at 6 and 12 months. Results: At 6 months, participants in the tailored print arm reported a median of 112.5 minutes of physical ac-tivity per week, those in the tailored Internet arm reported 120.0 minutes, and those in the standard Internet arm reported 90.0 minutes (P=.15). At 12 months, the physical activity minutes per week were 90.0, 90.0, and 80.0 for those in the tailored print, tailored Internet, and standard Internet arms, respectively (P=.74). Results indicated no significant differences between the 3 arms.Conclusions: The use of tailored Internet, tailored print, and standard Internet as part of a behavior change program increased physical activity behavior similarly. Because the use of the Internet was not different from the print-based intervention, this may be an opportunity to reach more sedentary adults in a more cost-effective way.

Objective: Between 31 and 35% of the college-aged population is overweight or obese, yet few weight loss trials for this population have been conducted. This study examined the feasibility, acceptability, and initial efficacy of a technology-based 8-week weight loss intervention among college students. Design and Methods: Students (N ¼ 52) were randomly assigned to one of the three arms: Facebook (n ¼ 17); Facebook Plus text messaging and personalized feedback (n ¼ 18); Waiting List control (n ¼ 17), with assessments at 4 weeks and 8 weeks (post-treatment). Participants were 20.47 6 2.19 years old, 86.45 6 17.11 kg, with a body mass index of 31.36 6 5.3 kg/m 2 . Participants were primarily female (86.5%), and the sample was racially diverse (57.7% Caucasian, 30.8% African American, 5.8% Hispanic, and 5.7% other races). Results: The primary outcome was weight loss after 8 weeks (post-treatment); 96.0% of the participants completed this assessment. At 8 weeks, the Facebook Plus group had significantly greater weight loss (À2.4 6 2.5 kg) than the Facebook (À0.63 6 2.4 kg) and Waiting List (À0.24 6 2.6 kg) (both Ps < 0.05). Weight change at 8 weeks was not significantly different between the Facebook and Waiting List groups. Conclusions: Results show preliminary efficacy and acceptability of the two active intervention arms (97.0% found the program helpful, 81.3% found the videos/handouts helpful, and 100% would recommend the program to others). Results indicate the potential for an innovative weight loss intervention that uses technology platforms (Facebook and text messaging) that are frequently used and already integrated into the cultural life of college students.

Automated telephone-linked delivery systems represent an effective alternative for delivering physical activity advice to inactive older adults.

Background: This report examines the outcome data for Project PREVENT, a two-site randomized control trial designed to reduce behavioral risk factors for colorectal cancer among individuals who have been diagnosed with adenomatous colon polyps. Methods: The study sample included 1,247 patients with recent diagnosis of adenomatous colorectal polyps. Within 4 weeks following the polypectomy, participants completed a baseline survey by telephone, and were randomized to either Usual Care (UC) or the PREVENT intervention, which was designed to target multiple risk factors. The intervention consisted of a telephone-delivered intervention plus tailored materials, and focused on the six primary behavioral risk factors for colorectal cancer, including red meat consumption, fruit and vegetable intake, multivitamin intake, alcohol, smoking, and physical inactivity.
