  1. aΔh2 = male % h2 – female % h2. The null hypothesis that Δh2 = 0 is equivalent to the null hypothesis that the sex-specific heritabilities are equal
  2. VPA: vigorous physical activity; MPA: moderate physical activity; WK: walking; ST: sitting time; TPA: total physical activity; WT: watching television
