Abstract

Background
Prolonged diarrhea, defined as diarrhea lasting longer than 7 days, is known to negatively impact children's growth and development. However, studies of the risk factors of prolonged diarrhea remain limited. Purpose: This study aimed to analyze the risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea.
Methods
This 1-year nested case-control study was conducted at Fatmawati General Hospital in 2021–2022. Participants were selected using a consecutive sampling method from among children under 2 years of age with acute diarrhea within the previous 2–4 days. Children with diarrhea that lasted 7 days were considered positive for prolonged diarrhea, whereas those with acute diarrhea were considered negative. Children with comorbidities such as malnutrition were excluded. Clinical information including age, breastfeeding history, antibiotic exposure history, and nutritional status was recorded. Complete blood count, blood zinc levels, Rotavirus, adenovirus, and norovirus serology, alpha-1 antitrypsin (AAT) levels, and stool analysis were acquired as laboratory data.
Results
There were 62 subjects in the study and control groups. Overall, the median age was 12 months (6–24 months); most patients were boys. A history of antibiotic use (odds ratio [OR], 15.860; 95% confidence interval [CI], 5.286–47.591; P<0.001), zinc deficiency (OR, 4.758; 95% CI, 1.711–13.229; P=0.003), and elevated fecal AAT levels (OR, 2.677; 95% CI, 1.046–6.850; P=0.040) were the main risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea.
Conclusion
A history of antibiotic use, zinc deficiency, and elevated fecal AAT levels were the main risk factors for prolonged diarrhea in children under 2 years of age with acute diarrhea. Thorough testing and appropriate antibiotic use are required to prevent prolonged diarrhea in children under 2 years of age.
