Relationship Between Nutritional Status, Contact History, and BCG Immunization Status and Child TB in RSD Tidore City

Introduction: Children of all ages can get tuberculosis (TB), an infectious disease. With 500,000 child TB cases annually and 40–50% of the population in poor nations being categorized as children, child TB is a significant disease to research. This study's main goal was to ascertain how nutritional status, contact history, and BCG immunization status related to childhood tuberculosis at Tidore Hospital in 2025.  Methods: This kind of study used a cross-sectional design and was analytically descriptive. In December 2025, there were 80 children with tuberculosis who visited the polyclinic on a regular basis, making up the study's population. Contact history has a significance level of 0.000 <0.05 and a t value of 3.564 > t table 1.665. This indicates that the Child TB variable is significantly impacted by the contact history variable to some extent. The t count value for immunization status is 4.055 > t table 1.665, with a significance of 0.000 <0.05. This indicates that the Child TB variable is significantly impacted by the Immunization Status variable to some extent. The Nutritional Status hypothesis was tested, and the results reveal a t value of 3.044 > t table of 1.665 with a significance of 0.000 <0.05. This indicates that the Child TB variable is significantly impacted by the Nutritional Status variable to some extent.So the advice for health workers is that it is hoped that they will be more active in providing counseling or KIE, putting up poster media, and providing leaflets related to TB in children.
