Diet, physical activity, all-cause and cause-specific mortality: repeated measures considerations.

European journal of epidemiology·May 1, 2026·PMID 41849084

For clinicians interpreting lifestyle studies, this underscores that long-term patterns matter more than a one-time snapshot, and that repeated assessments provide a clearer picture of risk reduction.
