Cumulatively worm infections can cause nutritional loss of calories and proteins and blood loss that can cause anemia, inhibit physical development, mental, intellectual decline in children and work productivity, can decrease the body's resistance so easily affected by other diseases. The purpose of this study was to determine the relationship between hand washing habits and bathing habits with the incidence of worms. The research method used is cross sectional. The results of this study showed that there was a relationship between hand washing before eating and hand washing after  to the occurrence of worm infestation with p value of 0.02 and 0.04 respectively. The relationship of bathing habits also showed a statistical relationship with a p value of 0.03, whereas there was feces in the nails also showed a statistical relationship with a p value of 0.00. Conducting efforts to promote clean and good living behavior both at school and community. Improve the promotion of handwashing, especially handwashing with soap.

Method: This study uses a case control research design with the number of respondents each as many as 57 people. The sampling method used is total sampling Results: There is a statistical relationship between exclusive breastfeeding and the incidence of stunting. The p value is 0.01 with an OR value of 0.38. Meanwhile, maternal height has a p value of 0.84 (OR 1.08), family support has a p value of 0.49 (OR 0.49), exposure to cigarette smoke has a p value of 0.09 (OR 0.31) and socioeconomic has no statistical relationship. Conclusion: There is a relationship between exclusive breastfeeding and the incidence of stunting. Meanwhile, maternal height, family support, and exposure to cigarette smoke did not show a statistical relationship with the incidence of stunting Key words: Stunting, Toddler, psychosocial.
