A Multimodal Lifestyle and Mind-Body Intervention in Rural Primary Care: Implications for Metaflammation in an Appalachian Population.

Abstract

Background: Chronic metabolic diseases such as obesity, hypertension, type 2 diabetes, and mood disorders frequently cluster in under-resourced communities. Increasing evidence suggests these conditions may be influenced by persistent low-grade systemic inflammation (sometimes referred to as metaflammation), as well as cumulative physiologic stress and environmental constraints. Rural Appalachian populations experience a disproportionate burden of these conditions, often compounded by poverty, food deserts, limited healthcare access, and restricted availability of preventive services.

Objective: To describe clinical and functional outcomes of a multimodal lifestyle and stress-regulation intervention implemented within routine primary care in a rural Appalachian population with multimorbidity.

Setting: A rural primary care clinic serving an under-resourced Appalachian community in the United States.

Participants: Thirty adults with multimorbidity participated in a 12-week clinic-based intervention; 22 participants completed the program and were followed through six months.

Intervention: The intervention integrated lifestyle education, hydration optimization, nutrition awareness adapted to food-desert constraints, and mindfulness-based cognitive-somatic practices designed to support stress regulation and behavioral awareness.

Primary outcome measures: Clinical and patient-reported outcomes, including body weight, blood pressure, depressive symptoms (PHQ-9), anxiety symptoms (GAD-7), sleep quality, energy levels, cognitive clarity, medication burden, and available laboratory markers, including HbA1c and fasting glucose.

Results: Participants demonstrated improvements across metabolic, psychological, and functional domains. Mean PHQ-9 and GAD-7 scores decreased from approximately 18-22 at baseline to 6-9 at 12 weeks, with improvements largely sustained at six months. Weight reduction ranged from approximately 11-30 lb over the 12-week intervention period, with greater reductions observed among a subset of participants. Blood pressure and glycemic control improved, along with improvements in sleep quality, energy levels, and cognitive clarity.

Conclusions: The pragmatic lifestyle and stress-regulation intervention was associated with improvements across metabolic, psychological, and functional outcomes, indicating its potential as a complementary strategy for addressing chronic disease in underserved communities.
