Background/Aims: One of the diseases whose incidence is still high is worm infection, namely intestinal worms that are transmitted through the soil (soil transmitted helminthiasis). This study to analyze the incidence of Soil Transmitted Helminths Infection Based on Personal Hygiene and Defecation Treatment in Elementary School Children.

Methods: The research design used is an observational study with a case control study approach. The population in this study were all children diagnosed with worms from January to June 2021 as many as 60 cases and as many as 60 children who were not dewormed in the working area of the Bontonompo I Health Center, Gowa Regency. The sampling technique used was total sampling with inclusion and exclusion criteria. The data obtained were analyzed using the Chi-square test statistical formula with a degree of significance (α = 0.05) and to see clarity about the dynamics of the relationship between risk factors and effects seen through the value of the odds ratio (OR).

Results: The results of the study showed that Chi-square analysis with Pearson chi-square test between personal hygiene variables and the incidence of intestinal worms obtained a value of 0.000 < 0.05 (OR= 11,000, 95%CI 4.5-99.1). The defecation treatment variable also showed a significant relationship with a p value of 0.001 < 0.05 (OR= 5,000, 95%CI 4.5-99.1), so the alternative hypothesis was accepted. So that personal hygiene and defecation care are risk factors for the effect because OR > 1.

Conclusions: There is a relationship between personal hygiene and defecation care with the incidence of intestinal worms in children. Therefore, socialization about personal hygiene, treatment for defecation, and administration of deworming drugs is still carried out by the puskesmas in order to prevent an increase in the prevalence of worms in the future.
