Online Counseling to Enable Lifestyle-focused Obesity Treatment in Primary Care

Online Counseling to Enable Lifestyle-focused Obesity Treatment in Primary Care

With over half of the US population currently overweight and 31% of adults now obese, the primary care setting may represent an important source of weight-loss support, in the interest of cardiovascular prevention. Yet, although the US Preventive Services task force recommends that physicians screen all adult patients for obesity and offer intensive counseling and behavioral interventions to promote sustained weight loss for obese adults, the recommendation has not been widely implemented. The Internet may help overcome many of the barriers that have prevented intensive obesity counseling in the clinical setting. The aim of this study is to examine whether Internet-based interventions for developing healthier lifestyles can improve preventive health care in a cost-effective manner.

The study, Online counseling to enable lifestyle-focused obesity treatment in primary care, aims to translate an evidence-based lifestyle intervention into the primary care setting, using information technology to enable clinical lifestyle counseling. While the US Preventive Services Task Force (USPSTF) recommends that clinicians screen all adult patients for obesity and offer intensive counseling and behavioral interventions to promote sustained weight loss for obese adults, multiple barriers to intensive lifestyle counseling exist and the recommendation has not been widely implemented. By requiring physician referral, augmenting the health care team's access to behavioral expertise, and encouraging physician feedback to participating patients, we aim to integrate lifestyle issues into routine preventive medicine. We will examine change in weight, waist circumference, physical activity, quality of life, and will calculate intervention cost-effectiveness. We will ensure sustainability by using recruitment and adherence strategies that can be replicated in routine practice, and counseling staff who are representative of the educators employed in primary care practice. If an online strategy is effective, the extensive network of the University of Pittsburgh Medical Center Health System provides excellent infrastructure for supporting dissemination in the region. As such, this study may facilitate wide-spread adoption of current evidence-based preventive medicine guidelines recommending incorporation of intensive lifestyle interventions into primary care practice.
