ABSTRACT
Infant grows very fast. The critical period is started after the age of six months.This is because, in that period giving breastfeeding exclusively to the infant does notsufficiently fulfill the nutrition need. Growth interference in this period is closelyrelated with the infant's feedings. Therefore, if complementary feeding is not givencorrectly, it will cause the interference of optimal growth.The research result of complementary feeding increasing program finds thatthere is a big number of mothers who still do not understand about the way and theright time of complementary feeding. Based on SDKI's data, in 2002-2003, 47,9% ofthe infant were given pralacteal food and 50% of the infant had been givencomplementary feeding in the age of less than one month, and in the age of 2-3 monthsthe infant were given solid food. There has not ever been a research aboutcomplementary feeding being done in Bangka District.The aim of this research is to obtain the information about related factorsdealing with complementary feeding practices to the infant ages 0-12 months inSungailiat, Bangka District on 2008. The research uses quantitative approach and crosssectional design. The samples are mothers who have 0-12 months infant and live inSungailiat, Bangka District. The mothers are characterized as follows; breasting, neverbeen given MPASI donation from the government or complementary feeding programfor poor family, and able to participate in the research. The samples are taken by usinga rapid survey with cluster design. The cluster is a group of mothers who havehomogenic characteristic in the area of Integrated Health Service at Sungailiat. TheAnalisis faktor-faktor..., Desi Yanti, FKM UI, 2008sample number is 270 people and 30 clusters, which are chosen randomly. Therefore,each cluster needs 9 respondents.
