Heritability of height from second trimester of pregnancy until the age of 36 months.
Values reflect heritability estimates (95% confidence interval). Model in the Generation R Study: height (SDS) = β0+β1 * mid-parental height (SDS). Here the slope ‘β1’ is equal to the heritability ‘h2’ [7]. Prenatally height is femur length (SDS). Postnatal growth is additionally adjusted for gestational age at birth. Model in the Netherlands Twin Register: Full twin model with additive genetic (A), shared environmental (C) and non-shared environmental (E) factors.
Figure 2.
Heritability of weight from second trimester of pregnancy until the age of 36 months.
Values reflect heritability estimates (95% confidence interval). Model in the Generation R Study: weight (SDS) = β0+β1 * mid-parental weight (SDS). Here the slope ‘β1’ is equal to the heritability ‘h2’ [7]. Prenatally weight is estimated fetal weight (SDS). Postnatal growth is additionally adjusted for gestational age at birth. Model in the Netherlands Twin Register: Full twin model with additive genetic (A), shared environmental (C) and non-shared environmental (E) factors.
