An additi<strong>on</strong>al model was c<strong>on</strong>structed to examine the relati<strong>on</strong>ship between infant<br />

feeding practices and ECC in infants (Table 5.15). Traditi<strong>on</strong>ally, these infant feeding<br />

methods have <str<strong>on</strong>g>of</str<strong>on</strong>g>ten been implicated in c<strong>on</strong>tributing to the <strong>on</strong>set <str<strong>on</strong>g>of</str<strong>on</strong>g> decay in the primary<br />

dentiti<strong>on</strong> <str<strong>on</strong>g>of</str<strong>on</strong>g> infants. Two variables for infant feeding were created to handle exclusive<br />

bottle feeding, exclusive breastfeeding, and mixed feeding methods, with mixed feeding<br />

serving as the reference category. The model also included sippy cup use. N<strong>on</strong>e <str<strong>on</strong>g>of</str<strong>on</strong>g> these<br />

variables were significantly associated with ECC.<br />
