Abstract summary 

The popularity of yoga has surged in recent years; however, yoga practitioners have remained a largely homogenous population. Research reflects that most practitioners are of a higher socioeconomic status. There are access barriers to yoga for lower income individuals, likely due to factors such as financial constraints and logistical challenges. The primary goal of this review was to synthesize literature on yoga research among low-income populations and better understand the feasibility and acceptability of such interventions. A secondary goal was to assess the consistency of metrics for reporting feasibility and acceptability across such studies using the CheckList Standardizing the Reporting of Interventions for Yoga (CLARIFY) guidelines as a framework. Third, the authors sought to propose additional standardized CLARIFY guidelines that may enhance reporting on the diversity of yoga research populations, adherence, and retention. The electronic databases PubMed, PsycINFO, Cochrane Central Register of Controlled Trials, and Google Scholar were searched in May 2022 using a prespecified search string. Articles assessing a yoga intervention in predominantly low-income adult populations were deemed eligible for inclusion. The search resulted in 512 potential articles. Eleven were deemed eligible for inclusion. The included studies reported mostly positive effects of yoga on the target outcome (i.e., pain/disability, quality of life/wellness, and psychiatric symptoms). Recruitment and retention data showed generally good attendance and high study completion rates. Common study design components included recruitment embedded within preexisting medical settings, proximal yoga locations, and mitigation of yoga-related costs. Finally, the authors noted inconsistency in the reporting of adherence, retention, and other sociodemographic characteristics of participants and yoga instructors (e.g., race, ethnicity, and income). Yoga may promote physical and mental health for low-income individuals. Important facilitators to access are noted, such as proximal study settings, as well as barriers such as the need for childcare that can be addressed in future research. In addition, several study design considerations could help address the specific needs of low-income participants in yoga research, such as compensating participants, recruiting within existing medical settings, and providing yoga-related equipment at no cost. Finally, the authors suggest specific ways to enhance reporting of study metrics related to socioeconomic diversity, by adding to the preexisting CLARIFY guidelines.
