Outcomes of a 12-month web-based intervention for overweight and obese men.

Background: This study assessed the effect of a 1-year internet-based weight loss intervention for men.

Methods: Four hundred forty-one overweight and obese men were randomized to intervention or delayed treatment. Participants completed a Web-based assessment of diet and physical activity behaviors and weekly tailored Web modules addressing weight-related behaviors.

A review of eHealth interventions for physical activity and dietary behavior change.

Objective: To review eHealth intervention studies for adults and children that targeted behavior change for physical activity, healthy eating, or both behaviors.

Data Sources: Systematic literature searches were performed using five databases: MEDLINE, PsychInfo, CINAHL, ERIC, and the Cochrane Library to retrieve articles.

Study Inclusion And Exclusion Criteria: Articles published in scientific journals were included if they evaluated an intervention for physical activity and/or dietary behaviors, or focused on weight loss, used randomized or quasi-experimental designs, measured outcomes at baseline and a follow-up period, and included an intervention where participants interacted with some type of electronic technology either as the main intervention or an adjunct component.

Body image and self-esteem among adolescents undergoing an intervention targeting dietary and physical activity behaviors.

Purpose: To determine the effect of a one-year intervention targeting physical activity, sedentary, and diet behaviors among adolescents on self-reported body image and self-esteem. Health promotion interventions can lead to awareness of health risk and subsequent adoption of beneficial changes in behavior. However, it is possible that interventions targeting behaviors associated with childhood obesity may also increase the likelihood of unhealthy eating and physical activity obsessions and behaviors.

Patterns of sedentary behavior among adolescents.

Objective: Reducing certain sedentary behaviors (e.g., watching television, using a computer) can be an effective weight loss strategy for youth.

Psychosocial correlates of dietary intake among overweight and obese men.

Objectives: To investigate the relationship between theoretically based psychosocial constructs and dietary components among overweight men.

Methods: Participants were 441 men (BMI M = 34.2).

Psychosocial correlates of fruit, vegetable, and dietary fat intake among adolescent boys and girls.

Objective: This study examined whether hypothesized psychosocial correlates of behavior change (family/peer influence, pros, cons, self-efficacy, parent/child change strategies, and household eating rules) are associated with consumption of fruits, vegetables, and dietary fat among adolescent boys and girls.

Design: This cross-sectional study used questionnaires to assess psychosocial variables and multiple 24-hour recall interviews to assess dietary intake (daily servings of fruits and vegetables and percentage energy intake from dietary fat).

Subjects: In this study, 878 adolescents (53.

Randomized controlled trial of a primary care and home-based intervention for physical activity and nutrition behaviors: PACE+ for adolescents.

Objective: Many adolescents do not meet national guidelines for participation in regular moderate or vigorous physical activity (PA); limitations on sedentary behaviors; or dietary intake of fruits and vegetables, fiber, or total dietary fat. This study evaluated a health care-based intervention to improve these behaviors.

Design: Randomized controlled trial.

Prevention of eating disorders and obesity via the internet.

Internet technology has been expanding rapidly and has had a dramatic impact on how people communicate, learn and share information. This article presents applications of internet technology to the psychological domain, particularly in the prevention and treatment of eating disorders and obesity. Information regarding advantages and disadvantages of computerized interventions are discussed and several examples of randomized controlled trials with this technology are presented.

Prevalence, characteristics, and correlates of teasing experiences among overweight children vs. non-overweight peers.

Objective: Information regarding the prevalence, nature, sources, and psychosocial correlates of teasing was obtained for overweight (OV) children (10 to 14 years of age) vs. non-overweight (non-OV) peers. It was hypothesized that weight-related teasing would be negatively correlated with self-esteem in specific domains and with enjoyment of physical/social activities and positively correlated with loneliness, bulimic behaviors, body dissatisfaction, and enjoyment of sedentary/isolative activities.

An ecological framework for cancer communication: implications for research.

The field of cancer communication has undergone a major revolution as a result of the Internet. As recently as the early 1990s, face-to-face, print, and the telephone were the dominant methods of communication between health professionals and individuals in support of the prevention and treatment of cancer. Computer-supported interactive media existed, but this usually required sophisticated computer and video platforms that limited availability.

An interactive psychoeducational intervention for women at risk of developing an eating disorder.

This study evaluated a synchronous Internet-delivered intervention (chat room) for improving eating habits and body image in college-age women at risk for developing an eating disorder. Sixty at-risk women (mean age = 18.9, SD = 2.

Diet, physical activity, and sedentary behaviors as risk factors for overweight in adolescence.

Background: The proportion of overweight adolescents has increased, but the behavioral risk factors for overweight youth are not well understood.

Objective: To examine how diet, physical activity, and sedentary behaviors relate to overweight status in adolescents.

Design And Setting: Baseline data from the Patient-Centered Assessment and Counseling for Exercise Plus Nutrition Project, a randomized controlled trial of adolescents to determine the effects of a clinic-based intervention on physical activity and dietary behaviors.

Computer and Internet applications for psychological treatment: update for clinicians.

Computers and the Internet have the potential to be used to deliver psychological treatments. This article provides a selective review of applications involving little or no therapist contact, applications involving asynchronous and synchronous communication with providers, and applications that have been used as adjuncts to standard psychotherapy. Data on the efficacy of these applications most strongly support using the Internet to complete and submit behavioral assignments, to obtain social support from peers, and to receive education, feedback, and support from therapists in the form of e-mail or chatroom communications.

Overweight children's barriers to and support for physical activity.

Objective: As the epidemic of overweight increases among youth, research needs to examine factors that may influence children's participation in weight-related health behaviors. This study examined overweight children's perceived barriers to and support for physical activity compared with nonoverweight children.

Research Methods And Procedures: Barriers to and support for physical activity were examined among 84 overweight children attending a summer fitness camp or a university-based weight loss clinic.

Preliminary evaluation of a multicomponent program for nutrition and physical activity change in primary care: PACE+ for adults.

Background: Patient-centered Assessment and Counseling on Exercise plus nutrition (PACE+) is an intervention based in primary care settings to help patients change physical activity and dietary behaviors.

Methods: One hundred seventy-three adults were assessed before and after a 4-month intervention. All patients completed a computerized assessment and created tailored "action plans" to change one physical activity and one nutrition behavior that they then discussed with their provider.
