However, the acin telomere length and was not statistically significant. Step 2 tual rate of loss and the factors governing interindividual variability in the rate of loss in similarly aged persons are still   Parenting appears to be especially important unclear (Benetos et al., 2001; Frenck, Blackburn, & Shannon,   High-risk parents are less likely to respond sensitively to 1998; Hewakapuge, van Oorschot, Lewandowski, & Baindurchildren’s distress and synchronously in positive interactions.
