Anthropometricmeasurements were performed to obtain linear growth status.Data were analyzed by using odd ratio (OR). The first step wasperformed univariately to assess the effect of data variables.Henceforth, factors which significantly influence the growthwill be assesed by multivariate calculation.Results Normal linear growth status was found in 109 (66.1%)exclusively breastfed compared with 56 (33.9%) nonexclusivelybreastfed children. Univariate analyzes showed that factorsthat influenced children normal linear growth were exclusivebreast-feeding (OR: 2.44; 95%CI: 1.58;3.78), industrial productporridge as complementary food (OR: 1.65; 95%CI: 1.00;2.72),and frequency of illnesses <6x/year (OR: 1.57; 95%CI: 1.02;2.42).The result of multinomial logistic regression analyzes showed thatexclusive breast-feeding became the only factor that influencechildren linear growth (OR: 2.254; 95%CI: 1.438;3.533).Conclusion Exclusive breast-feeding has significant positive effect onlinear growth of children.
