Barriers and Facilitators of Physical Activity in People Living With HIV: A Systematic Review of Qualitative Studies

Abstract

Background

Most people living with HIV (PLWH) are sedentary. This study aimed to synthesize the findings of qualitative studies to understand barriers and facilitators of physical activity (PA) among PLWH, categorized using the Capability, Opportunity, Motivation-Behavior (COM-B) model and Theoretical Domains Framework (TDF).

Methods

Systematic searches of four databases were conducted to identify eligible studies. Thematic synthesis was used to inductively code, develop, and generate themes from the barriers and facilitators identified. Inductive data-driven themes were deductively categorized using the relevant domains of the COM-B model and the TDF.

Results

Fourteen articles were included. The most prominent TDF domain for barriers was skills, particularly symptoms/health issues such as fatigue and pain, while the most prominent TDF domain for facilitators was reinforcement, particularly experiencing benefits from PA.

Conclusion

The breadth of factors identified suggests the need for comprehensive strategies to address these challenges effectively and support PLWH in adopting and sustaining PA routines.

Introduction

According to the World Health Organization (WHO), approximately 39 million people worldwide were estimated to be living with human immunodeficiency virus (HIV) by the end of 2022; in the United States, the number is approximately 1.2 million.¹ Due to the introduction of effective antiretroviral therapy (ART), life expectancy in people living with HIV (PLWH) has significantly improved, leading to HIV being increasingly considered a chronic disease.² While the life expectancy of PLWH has increased, they tend to live with a higher burden of chronic diseases.³ Compared to their non-HIV-infected counterparts, PLWH are at an elevated risk for various comorbid conditions, including cardiovascular diseases (CVDs) and cognitive impairment, primarily due to prolonged HIV-associated inflammation, psychological distress, and side effects of ART.^4,5 Studies have shown that PLWH are 50% more likely to develop CVD⁶ and 58% more likely to develop dementia,⁷ conditions that can often interfere with medication adherence⁸ and are associated with higher mortality rates.⁹

Physical activity (PA) is an established lifestyle intervention that plays a crucial role in promoting overall well-being.¹⁰ Among PLWH, substantial research evidence has revealed the benefits of PA, including increased fitness, improved cardiovascular outcomes, enhanced mental health, and better quality of life.¹¹ To achieve substantial health benefits, PA needs to be performed regularly and maintained across the lifespan. The WHO guidelines recommend at least 150 min of moderate-intensity aerobic PA per week, along with muscle-strengthening activities on two or more days per week.¹² However, globally 50% to 80% of PLWH do not meet the guidelines.^13-15 To encourage participation in PA among PLWH, understanding barriers and facilitators of participation in PA in PLWH is an essential first step.

A series of studies have employed quantitative methodologies to identify correlates of participation in PA in PLWH, as exemplified in a recent quantitative systematic review by Vancampfort et al.¹⁶ Their review included 45 survey studies and highlighted factors associated with PA participation among PLWH. Older age, lower educational level, decreased CD4+ T cells/mm³, exposure to antiviral therapy, body pain, and depression emerged as primary barriers to PA. Conversely, higher cardiorespiratory fitness, greater self-efficacy, perceived benefits, and enhanced health motivation were identified as significant facilitators of PA. Although these quantitative studies have generated important objective correlates of PA, they do not allow in-depth consideration of barriers and enablers that are important to participants. To complement this understanding, qualitative research methodologies can offer valuable insights into participants’ perspectives.¹⁷ Over the past decade, emerging studies have used qualitative investigations to understand the PLWH's views on barriers and enablers of PA participation. However, a synthesis of these qualitative studies is still lacking to produce larger interpretive representations of studies examined and to inform health-related policy and practice.

The Theoretical Domains Framework (TDF) encompasses 14 theoretical domains synthesized from 33 behavior change theories and 84 theoretical constructs in a single framework.¹⁸ This framework comprehensively explores influences on behaviors and aligns with the Capability, Opportunity, Motivation-Behavior (COM-B) model, delineating how capability, opportunity, and motivation interact to shape behavior (Figure 1).¹⁹ By aligning the TDF with COM-B, one can elucidate how TDF domains interplay to impact behavior, facilitating the identification of potential behavior change techniques to inform interventions. The TDF is recommended for identifying and categorizing barriers and facilitators to behavior change and has been widely applied in clinical and community settings.^20,21 It has been increasingly used in systematic reviews as a structured coding framework for understanding barriers and facilitators of behavior change.^22,23

To provide guidance to policymakers and health care professionals, this study aimed to undertake a qualitative systematic review to understand barriers and facilitators influencing the participation of PA among PLWH, categorizing these using the TDF domains. The outcomes of this study will complement quantitative evidence, enhancing our comprehensive understanding of the factors influencing PA engagement among PLWH. Additionally, it will offer valuable insights for developing interventions, providing strategies to address the unique challenges that PLWH face in maintaining an active lifestyle.

Methods

This review was prospectively registered with PROSPERO (CRD42024516815) and is reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines (Supplemental File 1).

Eligibility Criteria

The inclusion criteria for this review were: (1) a diagnosis of HIV, regardless of the assessment method used, (2) participants aged 18 years or older, (3) studies utilizing qualitative research methods, and (4) studies investigating the barriers and facilitators of PA participation. For this review, a barrier was defined as “a circumstance or obstacle that keeps people or things apart or prevents communication or progress,” while a facilitator was defined as “a person or thing that makes something possible.”²⁴ Studies were excluded if they were not published in peer-reviewed journals or not written in English.

Search Strategy

A systematic search was conducted on February 29, 2024. Four databases (MEDLINE, CINAHL, SPORTDiscus, and EMBASE) were searched from inception to present. Search terms included “HIV,” “human immunodeficiency virus,” “AIDS,” “acquired immunodeficiency syndrome,” “Physical activity,” “Exercise,” “Walking,” “Activities of daily living,” “Barrier,” “Obstacle,” “Challenge,” “Facilitator,” “Enabler,” “Determinant,” “Influences,” “Attitudes,” “Experiences,” and “Adherence.” Two review authors (DS and YJY) independently conducted the literature search. Any discrepancies were resolved by a third review author (JW). The full search strategies for Medline are presented in Supplemental File 2.

Methodological Quality Appraisal

The quality assessment was conducted using the Critical Appraisal Skills Program checklist for qualitative studies.²⁵ The assessment covered domains such as research design, sampling and selection bias, attrition bias, performance bias, data collection, data analysis, and ethical considerations (Supplemental File 3). Each domain was evaluated by answering questions, with responses categorized as positive (+), negative (−), or not reported (NR). Quality was rated as strong (no risk of bias or risk of bias in one of the assessed domains), moderate (risk of bias in two domains), or weak (risk of bias in three or more domains). DS and YJY independently conducted the quality assessment. Any discrepancies were discussed and resolved, and consensus was reached on the final quality assessment ratings by both reviewers.

Data Collection

For each eligible study, study characteristics, participant's characteristics, and reported barriers and facilitators to PA were extracted using a self-designed standardized form. DS extracted data from all included studies, and YJY reviewed the extraction. Any disagreements were resolved through discussion.

Data Synthesis

Data were analyzed and synthesized using a data-driven bottom-up approach. Thomas and Harden's method of thematic synthesis²⁶ was employed to inductively code, develop, and generate themes from the barriers and facilitators identified across the included studies. Inductive data-driven themes were deductively categorized using the relevant domains of the COM-B model and the TDF. Frequency of reporting was utilized to determine how often the barriers and facilitators were discussed across the included studies. Two review authors (DS and YJY) independently coded the barriers and facilitators identified in the included studies to the relevant COM-B constructs and TDF domains, guided by the operational definitions prespecified by the authors (DS and YJY) (Supplemental File 4), based on definitions from Cane et al.¹⁸ Any discrepancies were resolved by a third review author (JW).

Ethical Approval and Informed Consent

Ethics approval and informed consent were not required for this systematic review.

Capability-Related Barriers

In terms of physical capability-related barriers, symptoms and health issues, including fatigue^{28,29,31,33,35,37} and pain,^28,29,35,39 were the most frequently cited barriers to PA participation among PLWH. Other symptoms and health issues affecting their ability of PLWH to engage in PA included medication side effects,^31,36 limited fitness capability,^29,35,36 comorbidities,^31,33,34,36 digestive issues,^29,33 respiratory issues,²⁹ dermatological symptoms,³⁷aging,³¹and stress.³⁸ Substance use was also identified as a barrier to PA in one study³⁴ (TDF skills). In terms of psychological capability-related barriers, lack of familiarity with PA^35,36 and knowledge regarding the use of PA equipment³⁶ was identified as barriers (TDF knowledge). People living with HIV also expressed difficulty memorizing a routine³⁶ (TDF memory) and easily falling out of an exercise routine³³ (TDF behavioral regulation) as additional barriers to engaging in PA.

Opportunity-Related Barriers

In terms of physical opportunity-related barriers, the most frequently cited barrier to PA among PLWH was lack of time.^{28,29,31-33,35,37} People living with HIV also expressed the lack of tailored programs,^28,31³⁵and instructions from providers^28,32,33,36 as barriers within this domain.

Capability-Related Facilitators

Physical capability-related facilitators included reduced fatigue and pain^29,31 (TDF skills). In terms of psychological capability-related facilitators, awareness of the benefits of PA^29,32 and knowledge of how to promote PA³⁴ were cited as facilitators to PA participation (TDF knowledge). The ability to develop a PA routine, including adjusting daily habits over time^36,40 and combining PA with other behaviors,³⁵ was identified as a facilitator (TDF behavioral regulation). Additionally, the absence of adverse effects of cognitive problems on exercise was identified as a facilitator (TDF memory, attention, decision processes).

Opportunity-Related Facilitators

The physical opportunity-related facilitators included environmental opportunity such as availability of facilities,^32,34,35 walkable community environment,³⁷ leisure²⁸ and convenient activities,³⁵ favorable weather,³⁴ and a nonjudgmental training atmosphere.³⁴ Tailored PA programs adapted to fatigue or other concurrent conditions^27,29,39 and a gradual approach,³⁹ as well as technology support such as feedback messages³⁰ and technology-empowered self-monitoring^36,40 were also facilitators. Professional's support^33,34,39 and financial support^29,34 (TDF environmental context and resources) were also noted. In terms of social opportunity, social support from family and friends,^{27-29,31,32,34-37,40} involvement in an organization,^28,29,31,37 and having a pet²⁹ were identified as significant facilitators to PA participation (TDF social influences).

Motivation-related facilitators

In terms of automatic motivation-related facilitators, experiencing the physical benefits of being active was the most cited motivator for PLWH (TDF reinforcement). These benefits included reduced fatigue/increased energy,^{29,31,32,34,36,39} improved functional capability,^28,33-36,39 clearer thinking,^31,34,39 and better sleep.³⁴ Mental health benefits such as improved mood^31,33-36,39 and elevated motivation,³³ as well as social benefits such as prevention of isolation^33,34,39 and improved relationship,³⁴ were also noted. Some PLWH expressed interest or enjoyment^28,29,33,35 and a sense of accomplishment^31,34 in being physically active (TDF emotion), viewing PA as a crucial self-management component^27,32,34 (TDF social/professional/identity). A positive attitude toward PA^27,36 was also identified as a facilitator (TDF optimism). In terms of reflective motivation-related facilitators, self-efficacy^{29,32,34,35,40} was frequently cited as a facilitator to engaging in PA (TDF beliefs about capabilities). Goal setting as a behavioral change strategy was used by some PLWH to facilitate PA engagement^29,31,36,40 (TDF goals). Belief in the health benefits of PA^29,32,36 was also a strong facilitator. Motivators to PA participation included desire to stay healthy,^31,36,40 social interaction,^34,36 resistance to aging,³⁴ aesthetics,³⁵ admiration,²⁹ and distraction.²⁹ Moreover, some PLWH expressed an intention to participate in PA because they prioritized it over other activities,^36,39 integrated it into their daily lives³⁹ and therapy routines,^29,34 and maintained an active lifestyle as a personal norm³³ (TDF intention).

Discussion

This systematic review represents the first comprehensive synthesize of qualitative research on barriers and facilitators to PA among PLWH, mapping these factors to the COM-B and TDF. Our findings underscore the multifaceted nature of factors influencing PA engagement, which can act as both barriers and facilitators depending on individual contexts. Importantly, facilitators identified by PLWH inform strategies aimed at supporting PA engagement.

Regarding barriers, the most prominent TDF domain identified was skills, particularly symptoms and health issues such as fatigue and pain. These findings align with a previous quantitative systematic review of PA correlates for PLWH¹⁶ indicating that physical capability-related barriers among PLWH, including comorbidities, treatment side effects, and pain, consistently hinder PA among PLWH. People living with HIV advocated for tailored PA programs accommodating their physical capabilities,^27,29,39 viewing these as facilitators to PA. The domain of environmental context and resources emerged as the second most prominent barrier, highlighting issues such as inadequate facilities and time constraints. Addressing this domain through resource provision, including facilities and tailored programs, is crucial.⁴¹ Additionally, wearable devices and mobile phones were endorsed as potential facilitators for future PA programs.^30,36,40

Social influence was the third most prominent barrier domain, with lack of social support being a significant hindrance. Conversely, positive social support from family and friends emerged as the most cited facilitator to PA perceived, underscoring the importance of educating support networks about PA's benefits.

In terms of facilitators, reinforcement, social influences, and environmental context and resources were the most prominent TDF domains. Experiencing benefits from PA, such as improvements in physical health, mental well-being, and social connections, was highlighted as a crucial form of reinforcement. This positive reinforcement also influenced intention and optimism, as per the COM-B model,¹⁹ suggesting that emphasizing positive outcomes and providing role model experiences could enhance engagement. Goal setting emerged as another prominent facilitator, emphasizing its role as a key behavioral change strategy.⁴²

Strengths and Limitations

Regarding strengths, firstly, this study complements the findings of previous reviews that focused solely on quantitative studies by including qualitative research. This inclusion deepens the understanding of the barriers and facilitators of PA engagement from the perspective of PLWH. Additionally, the application of a theoretical framework to classify the barriers and facilitators impacting PLWH's PA engagement enhances the robustness of this review. This systematic approach may aid researchers and professionals in selecting appropriate behavioral change techniques for designing future PA programs.

As for limitations, firstly, most studies were conducted in North America. This regional focus may limit the generalizability of findings, as barriers and facilitators of PA for PLWH in other jurisdictions could differ. Additionally, since many included qualitative studies utilized thematic analysis, our coding of barriers and facilitators may be constrained by the interpretations and analyses of the primary studies.

Conclusion

In conclusion, this qualitative systematic review advances our understanding of theoretical factors influencing PA among PLWH. Given the challenges of inadequate PA guideline adherence among PLWH, these findings provide actionable insights for researchers, policymakers, and practitioners to develop targeted, theory-based interventions supporting PA adoption and maintenance among PLWH.
