Impact of Oral Health on Potential Categories of Dietary Patterns in Chinese Older Adults: Based on the 2018 Chinese Longitudinal Healthy Longevity Survey Dataset

We identified four dietary patterns through LCA and noted that oral health status significantly affects dietary preferences among older adults. Adaptive eating behaviours influenced by cultural and socioeconomic factors aid in reducing the negative impact of oral health issues on diet. Our results indicated a dynamic, multifactorial relationship between oral health and dietary patterns in the older population, underscoring the necessity for integrated interventions combining oral care with dietary guidance.
