Sustainable Development Goal 3 is one of the priorities in Hong Kong. SDG 3 addresses all major health priorities and seeks to ensure health and well-being for all at every stage of life. It also calls for more research and development, increased health financing, and strengthened capacity of all countries in health risk reduction and management. Overcoming diseases and ill health will require concerted and sustained efforts, focusing on population groups and regions that have been neglected. The 2020 COVID-19 pandemic is devastating health systems globally and threatens health outcomes already achieved. Older persons are considered as the vulnerable population as they are at a high prevalence of comorbidity and disabilities. They need sufficient health services to maintain health and to manage serious and continuing chronic illnesses. Therefore, strengthening the prevention and health service delivery for older people should receive more attention in all countries to achieve healthy ageing. The chapter will discuss how SDG 3 could benefit the elderly population and review how the governments, the healthcare profession and the community can and should cooperate to accomplish health improvement and quality of life among the elderly in Hong Kong, as a case presentation.
