title: A summary index of infant and child feeding practices is associated with child growth in urban Shanghai.
abstract: BACKGROUND
  Recently, an infant and child feeding index (ICFI) constructed on brief recalls of breastfeeding, feeding frequency and food diversification was assumed to provide long-term prediction about child feeding practices. The aim of this study was to investigate the association between the cross-sectional ICFI (CS-ICFI) or longitudinal ICFI (L-ICFI) and child anthropometric indices in downtown Shanghai, China.
  
  
  METHODS
  The prospective cohort study included 180 infants aged 5-7 mo with their main caregivers who were visited 3 times every 6 months over 12 months. A CS-ICFI was constructed for each visit by using data on feeding practices based on 24-h and 7-d recalls. An L-ICFI was constructed with use of the 3 CS-ICFIs. The associations between ICFI and length-for-age z score (LAZ), weight-for-age z score (WAZ), and weight-for-length z score (WLZ) were examined. The stability of the CS-ICFI was assessed by using repeatability coefficient (RC).
  
  
  RESULTS
  The L-ICFI was positively associated with LAZ and WAZ at Visit 3(beta = 0.151, P = 0.040 and beta = 0.173, P = 0.024, respectively). Moreover, the CS-ICFI at Visit 1 was positively associated with LAZ, WAZ and WLZ (beta = 0.160, P = 0.029; beta = 0.191, P = 0.009; beta = 0.176, P = 0.020) at Visit 3, and the CS-ICFI at Visit 3 was also positively associated with LAZ (beta = 0.176, P = 0.016). Stability of the CS-ICFI was shown by the value of 0.14 (95% CI: 0.07, 0.31) of the RC, which differed significantly from 0 (P < 0.05).
  
  
  CONCLUSIONS
  The ICFI constructed on brief recalls based on cross-sectional studies can be used to evaluate the effects of child feeding practice on child growth.
