A urine-based age score helped predict future disease and death risk, beyond a person’s age in years. Researchers built the score using urine samples from a large general-population group. They measured small chemicals left behind as the body processes food and energy. Computer models used those measurements to estimate how old the body appeared. The team then tracked changes in the score over more than a decade. The score changed at different rates for different people. It also lined up with several health measures related to aging. It helped predict multiple future diseases and deaths from any cause. Those links remained after accounting for age in years. The source summary does not give the group’s size or the strength of these links. It also does not name the diseases involved. For this community, the type of age score matters. BioSocial’s Metabolic Age compares resting calorie burn with typical values at different ages. The study’s urine-based score measures something different, despite sharing the same name. These findings do not show that a calorie-burn-based score predicts the same risks. For members tracking their own numbers, that difference helps keep comparisons useful. Sharing how a score was measured gives community peers needed context. A change over time is easier to discuss when the measurement method stays consistent. This study did not test whether any habit could lower the urine score or reduce disease risk. What changes have you seen in your Metabolic Age, and how was it measured?
