Обзор

This study evaluates the effectiveness of a web-based obesity management program HealthyWeightCoaching (HWC), within a HealthyWeightHub.fi (HWH) platform. HWC is a 12-month intervention within a real-life clinical setting. The program includes a combination of nutrition, physical activity, and cognitive behavioral approaches, with a strong basis in acceptance and commitment therapy. In addition to the automated, interactive program, HWC includes a personal coach allocated to each patient. The patients are enrolled through referrals from primary care, occupational health, other hospitals, or from private health care units nationwide in Finland.

Подробное описание

Obesity is one of the major public health problems globally and it increases the risk of many obesity-associated diseases. Treatment of obesity requires long-term interventions, but nevertheless, it is challenging to provide long-term treatment when resources in real-life health care systems are limited. New cost-effective and accessible intervention methods are needed.

The modern treatment of obesity is based on behavioral changes that modify one´s daily lifestyle, which, according to recent research, are effective especially in the prevention of diabetes. However, little is known about the utilization and effectiveness of online programs using novel interactive technologies.

The aim of this study is to evaluate the effectiveness of a real-life web-based obesity management program (HealthyWeightCoaching, HWC) on weight loss, health, quality of life, and factors predicting long term success in treating overweight adult patients.

Healthy Weight Coaching is a novel 12-month intervention within a real-life clinical setting. The program includes a combination of nutrition, physical activity, and cognitive behavioral approaches, with a strong basis in acceptance and commitment therapy. The program is structured around weekly exercise modules.

In addition to the automated, interactive program, HWC includes a personal coach allocated to each patient. The patients are enrolled through referrals from primary care, occupational health, other hospitals, or from private health care units nationwide in Finland. The program is free for the patient to use.

The 12-month intervention is followed by a 5-year monitoring period. Questionnaires on health, quality of life, and lifestyle are collected at 0, 3, 6, 9, and 12-month time points. Body weight is collected by weekly logs. The recruitment is ongoing as the program is currently used in clinical practice.
