Table 2 Descriptive statistics for feed-to-feed interval and duration in diary (first week of life), by feeding group, N=502

From: Do early infant feeding patterns relate to breast-feeding continuation and weight gain? Data from a longitudinal cohort study

   Feed-to-feed interval (h) Feed duration (min)
Feeding group a N Mean (s.d.) Range 25th Median 75th Range
BREAST 172 2.71 (0.66) 1.46–5.07 16.3 21.7 28.0 7–60
BOTTLE 278 3.25 (0.55) 1.53–5.23 15.3 21.4 28.8 4–58
MIXED 52 3.14 (0.55) 1.98–4.25 16.3 24.4 29.4 2–50
P   <0.001 (ANOVA) *   0.292 (Kruskal-Wallis)    
  1. aBREAST=exclusively breast-fed, BOTTLE=exclusively bottle-fed, MIXED=both breast and bottle fed, as recorded in diary.
  2. *Significant differences (P<0.001) in mean feed interval for BREAST vs BOTTLE and also for BREAST vs MIXED, LSD post hoc tests.
