Table 4 Relationship between cognitive tests at age 60–64 years and residual changes in BMI between three time periods: BMI36–43 = 36–43 years, BMI43–53 = 43–53 years, and BMI53–60 to 64 = 53–60 to 64 years

  1. Linear regression models were used to assess associations between variables. Significant associations (p < 0.05) are highlighted in bold
  2. aIndicates log transformed dependent variables. MODEL 1 adjusted for sex, education and childhood cognition; MODEL 2 = MODEL 1 + adjustments for socioeconomic position at age 53, systolic blood pressure and heart rate at age 60–64; MODEL 3 (fully adjusted) = MODEL 2 + adjustments for total cholesterol, smoking, diabetes, diabetes duration and levels of physical activity. In each model, inverse probability weighting was implemented to account for dropout due to death
  3. VMT verbal memory test, LSST letter search speed test, S-RT simple reaction time test, C-RT choice reaction time
