Background: The relationship between childhood and adulthood socioeconomic status (SES) and long-term frailty trajectories is unclear. We aimed to assess the frailty index (FI) dynamic trajectories and examine the associations between childhood and adulthood SES and frailty trajectories.
Methods: We included 7321 participants aged 45 and older from the 2011-2020 China Health and Retirement Longitudinal Study (CHARLS).
Background: Previous studies using a single obesity indicator cannot fully assess the association between body shape and mortality. We aimed to investigate the association between complementary anthropometric measures and all-cause mortality risk.
Methods: We combined National Health and Nutrition Examination Survey (NHANES) data from 2011 to 2016 with mortality data up to December 31, 2019.
