  1. 1- and 6-month characteristics of 123 Hispanic mother-infant dyads from the Southern California Mother’s Milk Study. Data are reported mean and standard deviation (SD) unless otherwise noted. Breastfeeding frequency at 6 months of age is shown dichotomized as ≥ 7 or < 7 times per day. Total subcutaneous fat is the sum of the four infant skinfold thickness measures in millimeters. The Central:Total subcutaneous fat variable is the sum of the suprailiac and subscapular skinfold thicknesses divided by all four skinfold measures
