This study focuses on Beijing community residents aged 60 and above, aiming to understand how urinary function (like bladder or kidney function) and multiple health problems (such as high blood pressure, diabetes) affect each other as people age-since current studies often only look at single diseases and don't cover this group well. To join, participants need to be a 60+ Beijing community resident who can answer simple questions; those with serious mental illnesses or expected lifespan under 1 year can't take part. The study starts with a baseline check (asking about the participants' health, habits, doing blood/urine tests or urinary function assessments, and possibly collecting small blood/urine samples). After that, the investigators will follow up every 6-12 months (via phone or clinic to update health info) and repeat key checks yearly; people with lower cognitive ability will be checked every 3 months. The investigators will also record new illnesses, mobility issues (like falls), or death. The study has passed ethical review-participants will get clear info before joining, can quit anytime, and participants' data will stay private; participants will also get free health check reports and basic advice. For participants, this means regular health monitoring; for everyone, it'll help make tools to spot high-risk groups (like a community app), design better help (e.g., exercise plans), and push for yearly urinary health checks in communities.
