Title: Oral Health & Active Ageing                                                             


Our world is ageing and is ageing fast. In 2020 there were more than a billion people aged 60 and older, and many of them are living in China & South East Asia. In response to the aging population, The United Nations General Assembly declared 2021–2030 the’ Decade of Healthy Ageing’ in December 2020 with World Health Organization was asked to lead on its implementation. In this presentation we will review the dimensions and domains of oral health associated with active aging. The association between oral health and mortality – all cause mortality and disease-specific mortality. The impact of oral health on diet and nutrition – the specific oral health factors and methods for assessing nutritional status, as well as the evidence of the benefits of oral rehabilitation for improvement of nutritional status among those malnourished/ or ‘at risk’. There has been considerable research into how oral health contributes to ‘frailty’ and vice-versa, and much interest in ‘oral frailty’, how it develops and how to assess it. There has been a growing interest in the relationship between oral health and cognitive decline, the potential mechanisms at play, and much debate about the implications of this for geriatric care. There is limited evidence of how social networks and social capital affects older people’s oral health.  Specific examples from local studies will be provided with a wealth of evidence from the Chinese Longitudinal Healthy Longevity Study.
