Healthy weight (at both age 18 and ≥70 years), overweight (at either or both times), non-obese (age 18 years) to obesity (age ≥ 70 years), obesity (age 18 years) to non-obese (age ≥ 70 years), and early and later life obesity (at age 18 and ≥70 years). n = number of observations; SD = standard deviation; p-Values are from ANOVA or Wilcoxon rank-sum tests (continuous), or Chi-square tests (categorical variables). SEIFA: the socioeconomic indexes for areas based on the Index of Relative Socioeconomic Advantage and Disadvantage, which is based on residential postcode.
