<![CDATA[Wasting is a problem of acute malnutrition that affects growth, development, and increases the risk of morbidity and mortality in toddlers. The prevalence of wasting in the working area of the East Martapura Health Center is 21.4%, higher than the national average. This study aims to determine the relationship between birth weight history, breastfeeding, and infectious diseases in wasting toddlers aged 12-59 months in the working area of the East Martapura Health Center. This type of research is observational analytic with a case control approach. A sample of 96 toddlers consisting of 48 wasting toddlers (cases) and 48 non-wasting toddlers (controls) were taken using cluster random sampling. Data were collected through interviews, anthropometric measurements, and KMS/KIA documentation. Data analysis used the Chi-Square test. The results of the univariate analysis showed that toddlers with a history of LBW were 27%, did not receive exclusive breastfeeding 69.7%, and had a history of infectious diseases 75%. The results of the bivariate analysis showed a significant relationship between birth weight history and wasting (p=0.000; OR=6.689), breastfeeding with wasting (p=0.001; OR=4.956), and infectious diseases with wasting (p=0.018; OR=3.212). Toddlers with a history of LBW, not receiving exclusive breastfeeding, and having a history of infectious diseases have a higher risk of wasting. It is recommended that health centers improve education about exclusive breastfeeding and preventing infectious diseases in toddlers]]>
