Enhancing the Efficacy of Behavior Therapy for Obesity. Effects of Aerobic Exercise and a Multicomponent Maintenance Program
This study tested whether the efficacy of behavior therapy for obesity might be improved by the programmatic additions of an aerobic exercise regimen during treatment and a multicomponent maintenance program following treatment. Moderately obese volunteers were randomly assigned to one of four conditions in a 2 × 2 factorial design. Two treatment conditions (behavior therapy or behavior therapy plus aerobic exercise) were crossed with two post-treatment conditions (no further contact or a multicomponent maintenance program). The exercise regimen consisted of 80 min per week of brisk walking or stationary cycling. The maintenance program included client-therapist contact by telephone and mail and peer self-help group meetings. At posttreatment, clients in the behavior therapy plus aerobic exercise condition lost significantly more weight than those who received behavior therapy only. Over an 18-month follow-up period, maintenance program participants demonstrated significantly better weight-loss progress than clients in the no-further-contact condition.

- "The patients who exercised put on 4.8 kg as compared with 6 kg in the controls. A number of studies (Perri et al., 1986; Pedersen and Saltin Sikand et al., 1988; King et al., 1989; Pavlou et al., 1989; van Dale et al., 1990; Wadden et al., 1998) have assessed patients (n 5 475) who were randomized to a weight-loss program with or without physical training . After 1–2 years, the training group had put on an average of 4.8 kg as compared with 6.6 kg in the control group. "

ABSTRACT: Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

ABSTRACT: Social support is important to achieve beneficial changes in risk factors for disease, such as overweight and obesity. This paper presents the theoretical and practical framework for social support, and the mechanisms by which social support affects body weight. The theoretical and practical framework is supported with a literature review addressing studies involving a social support intervention for weight loss and weight loss maintenance. A major aspect in social support research and practice is the distinction between structural and functional support. Structural support refers to the availability of potential support-givers, while functional support refers to the perception of support. Interventions often affect structural support, for example, through peer groups, yet functional support shows a stronger correlation with health. Although positive correlations between social support and health have been shown, social support may also counteract health behaviour change. Most interventions discussed in this review showed positive health outcomes. Surprisingly, social support was clearly defined on a practical level in hardly any studies, and social support was assessed as an outcome variable in even fewer studies. Future social support intervention research would benefit from clear definitions of social support, a clear description of the intended mechanism of action and the actual intervention, and the inclusion of perceived social support as a study outcome.

ABSTRACT: This study evaluated the effectiveness of two posttreatment programs designed to enhance the maintenance of weight loss. Eighty-five obese clients were randomly assigned to either (a) behavior therapy plus a peer-support maintenance program, (b) behavior therapy plus a therapist-contact maintenance program, or (c) behavior therapy only. At a 7-month follow-up session, the therapist-contact program resulted in significantly greater maintenance of weight loss compared with the peer support and behavior therapy only conditions. However, by the time of an 18-month follow-up assessment, overall relapse rates were equivalent across conditions. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
