Dosing of Health and Wellness Coaching for Obesity and Type 2 Diabetes: Research Synthesis to Derive Recommendations.

Health and wellness coaching (HWC) is an effective intervention for lifestyle disease such as obesity and type 2 diabetes. The evolving HWC profession needs recommendations to guide clinical practice, particularly the appropriate dose of coaching. The purpose of this paper was to systematically review and synthesize HWC literature to derive HWC programming recommendations. Of 102 papers retrieved, 88 were retained with data extracted determining HWC session number, frequency, duration, program length, and total coaching load. Differential analysis yielded no statistical difference in programming variables for randomized control trials and other designs, nor for studies with significant findings v. those not finding statistical significance, allowing these data to be pooled. The HWC intervention for obesity was slightly more intense (15 sessions over 7-8 mo) than the diabetes programming (12 sessions over 9-10 mo). On average, HWC programming applied in the peer-reviewed literature was 12-15 sessions of 35-40 min duration over 7-9 months. These recommendations for HWC programming variables are put forth as initial practice guidelines and should be examined with comparative effectiveness study for optimization. HWC best practice guidelines for other patient groups (e.g., heart disease, cancer, and chronic pain) should also be studied once an adequate literature data base is available.

Compendium of the Health and Wellness Coaching Literature.

Health and wellness coaching (HWC) for lifestyle behavior change is emerging as a practice, role, and profession, in diverse health care, employee wellness, and community settings. Health care professionals apply HWC as a behavior change methodology for the prevention and treatment of diabetes, hypertension, hyperlipidemia, heart disease, cancer, and other chronic disorders. The purpose of this systematic review was to provide a comprehensive and organized compendium of HWC literature. To date, extant HWC literature remains scattered with no meaningful summary accessible. Lack of comprehensive summary stems from lack of consensus on HWC definition and standards. We applied a recently proposed, standardized definition of HWC to determine compendium inclusion criteria for peer-reviewed, data-based literature from relevant search engines (ie, PubMed, PsychInfo, and CINAHL). A systematic review process was executed and ultimately yielded 219 articles meeting HWC inclusion criteria. Of these, 150 were data-based and the remainder were expert opinion or review-style articles. A summary of results generally reveals HWC as a promising intervention for chronic diseases though further research is needed in most categories. The resulting HWC compendium organizes and describes the quantity and quality of available literature for the use and benefit of HWC practitioners and researchers.
