Abstract Background As the popularity and demonstrated effectiveness of Health and Wellness Coaching (HWC) continue to grow to address chronic disease prevalence worldwide, delivery of this approach in a group format is gaining traction, particularly in healthcare. Nonetheless, very little empirical work exists on group coaching and there are currently no published competencies for Group Health and Wellness Coaching (GHWC). Methods We used a well-established two-phase (Development and Judgment) process to create and validate GHWC competencies with strong content validity. Results Seven highly qualified Subject Matter Experts systematically identified and proposed the GHWC competencies, which were then validated by 78 National Board Certified Health and Wellness Coaches (NBC-HWCs) currently practicing GHWC who rated the importance and use frequency of each one. The validation study led to 72 competencies which are organized into the structure and process of GHWC. Conclusions GHWC requires not only coaching skills, but significant group facilitation skills to guide the group process to best support members in maximizing health and well-being through self-directed behavioral change. As the presence of HWC continues to grow, it is imperative that GHWC skill standards be accepted and implemented for the safety of the public, the effectiveness of the intervention, and the value analysis of the field. Such standards will guide curriculum development, allow for a more robust research agenda, and give practical guidance for health and wellness coaches to responsibly run groups. High quality standards for GHWC are particularly needed in health care, where a Level III Current Procedural Terminology (CPT®) code for GHWC has been approved in the United States since 2019 and reimbursement of such has been approved by the Centers for Medicare and Medicaid for 2024.

Cigarette smoking is irrefutably the strongest risk factor for lung cancer; however, approximately 25% of cases worldwide occur among nonsmokers. The age-adjusted annual incidence rate of lung cancer in Shanghai, a region where relatively few women smoke cigarettes, is one of the highest in the world. To help further elucidate the etiology of lung cancer among nonsmokers, the authors examined hormonal factors among women who were lifetime nonsmokers. They analyzed data from the prospective Shanghai Womens Health Study, which recruited Chinese women aged 40–70 years between 1996 and 2000 from selected urban communities. The current analysis included 71,314 women (n = 220 cases) who were lifetime nonsmokers and had no history of cancer at baseline. Later age at menopause (≥51 vs. <46 years; hazard ratio (HR) = 0.63, 95% confidence interval (CI): 0.40, 1.00), longer reproductive period (≥36 vs. <31 years; HR = 0.60, 95% CI: 0.39, 0.93), higher parity (≥4 vs. 0 children; HR = 0.42, 95% CI: 0.19, 0.90), and intrauterine device use (HR = 0.59, 95% CI: 0.41, 0.86) were associated with decreased risks of lung cancer. This large prospective study suggests a potential role for hormonal factors in the etiology of lung cancer among nonsmoking women. [ABSTRACT FROM AUTHOR]
