Patient-Identified Barriers and Facilitators to Weight Loss in Obesity with OSAHS

Overview

This qualitative study used the Theoretical Domains Framework (TDF) to explore patient-perceived challenges and supportive factors influencing weight loss among individuals with obesity and obstructive sleep apnea-hypopnea syndrome (OSAHS). Key findings revealed that knowledge misconceptions, lack of behavioral skills, self-regulatory deficits, and environmental disruptions hinder weight management, while social support and structured professional guidance facilitate adherence.

Background

Obstructive sleep apnea-hypopnea syndrome (OSAHS) is a common disorder strongly linked to obesity, which exacerbates its severity and associated cardiovascular risks. Weight loss is a primary therapeutic strategy shown to improve OSAHS parameters and overall health. However, behavioral interventions often fail long-term due to complex cognitive, psychological, social, and environmental barriers, compounded by OSAHS-specific symptoms like excessive daytime sleepiness. The Theoretical Domains Framework (TDF) integrates multiple behavioral theories to systematically identify these multidimensional factors influencing health behavior change.

Data Highlights

Participants: 26 individuals with obesity and OSAHS (mean age 43.2 ± 9.9 years; 73.1% male) from a tertiary sleep clinic in China.
Methodology: Semi-structured interviews analyzed using abductive thematic analysis mapped onto all 14 TDF domains.
Key quantitative data: Over 70% of patients experience weight regain after initial loss; a 10% weight gain increases OSAHS risk by 32% and moderate-to-severe OSAHS likelihood sixfold.

Key Findings

• Knowledge misconceptions influenced treatment preferences and hindered effective weight loss strategies.
• Insufficient behavioral repertoire, rather than lack of motivation, was a primary barrier to successful weight management.
• Self-regulatory deficits manifested as passive drift from weight loss goals.
• Environmental disruptions caused feelings of helplessness, negatively impacting adherence.
• Social influences had dual effects: supportive family members enhanced adherence, but some well-intentioned behaviors undermined efforts.
• Facilitators included personal experience-based knowledge, health-related anxiety as motivation, and desire for structured professional guidance.

Clinical Implications

Clinicians should address patient misconceptions and focus on building behavioral skills to improve weight loss outcomes in OSAHS patients. Interventions must consider self-regulation support and environmental modifications to reduce helplessness. Incorporating family support while educating on potentially counterproductive behaviors can enhance adherence. Structured, personalized professional guidance is critical to sustain long-term weight management.

Conclusion

Applying the TDF to weight management in obesity with OSAHS identified multifaceted barriers and facilitators across capability, opportunity, and motivation domains. These insights support the development of comprehensive, theory-informed interventions tailored to this population’s unique challenges.
