Eating behaviors among chinese older adults: A qualitative study using the capability, opportunity, motivation, and behavior model
Objective
This study explored the mechanisms underlying eating behaviors among Chinese older adults using the COM-B model, which conceptualizes behavior through Capability, Opportunity, and Motivation components.
Methods
A qualitative descriptive design was adopted. Semi-structured interviews were conducted with 20 community-dwelling older adults in Zhenjiang, Jiangsu Province, China, from October to December 2024. Thematic analysis was employed to analyze the data.
Results
Four major themes were identified: Restrictive Eating, Emotional Eating, Nutritional Literacy, and External Eating. Dietary patterns were influenced by physical health conditions, emotional states, family dynamics, and digital barriers to food information access.
Conclusions
Eating behaviors among older adults are shaped by complex and interconnected factors across individual, social, and environmental domains. Interventions promoting healthy aging should integrate strategies to enhance capability, optimize opportunity, and strengthen motivation.
