  1. LBW infant defined as delivery of any infant weighting less than 5 ½ pounds at birth. Breastfeeding defined as breastfeeding any infant for 1 month or more. CVD deaths defined as death with heart disease (I00–I09, I11, I13 and I20-I51) or cerebrovascular disease (I60-I69) identified as the leading cause of death. CVD deaths + surrogate CVD defined as CVD deaths and deaths with diabetes or hypertension as a secondary cause of death
  2. Percent data are weighted by the sampling weights % ± standard error
  3. The groups of women with and without a pregnancy-related risk factor do not add up to the column total due to missing data for that risk factor. (LBW missing, n = 168; Breastfeeding missing, n = 143)
  4. CVD, cardiovascular disease; LBW, low birthweight
