Prevalence of malnutrition & anemia in preschool children; a single center study.

BACKGROUND: Malnutrition including undernutrition, overnutrition, and micronutrient deficiencies are considerable problems worldwide, with variable burdens among different communities. Its complications include physical and cognitive impairment, with the probability of irreversible lifelong consequences. We aimed to assess the prevalence of undernutrition, overweight, obesity, and anemia in preschoolers, being a risk group for developmental adverse events. METHODS: We recruited 505 healthy preschool children, with a male: female ratio of 1.05:1. Children with chronic diseases were excluded. We used anthropometry and complete blood count to screen for malnutrition and anemia. RESULTS: The mean age of the study group was 3.8 ± 1.4 years (1.02-7). The screening results were average in 228 (45.1%) children, while 277 (54.9%) children had either abnormal anthropometry, anemia, or both. We observed undernutrition in 48 (9.5%) children; among them, 33 (6.6%) were underweight, 33 (6.6%) wasted, and 15 (3%) were stunted, with no significant difference between children aged below or above five. We identified overnutrition in 125 (24.8%); 43 (8.5%) were overweight, 12 (2.4%) were obese, and 70 (13.9%) had a high body mass index Z score, not qualifying the definition of overweight. Anemia was diagnosed in 141 (27.9%) children and was significantly more frequent among older children without gender discrimination. About 10% (50 children) had both anemia and abnormal anthropometry. The frequency of abnormal anthropometry was comparable between children with anemia and those with normal hemoglobin. CONCLUSION: Malnutrition and anemia in preschoolers are still a heavy burden affecting about half of our study group, with an upward trend towards the overnutrition side. Anemia is still a moderate public health problem in preschoolers.

Infection with adenovirus, rotavirus, and coinfection among hospitalized children with gastroenteritis in an Egyptian university hospital.

Acute gastroenteritis is the main cause of mortality and morbidity in children worldwide. Studies stated that rotavirus and human adenovirus (HAdV) are common causes of nonbacterial gastroenteritis in children aged 0-5 years. The aim of this study was to determine the prevalence and the distribution of rotavirus, HAdV, and coinfections among hospitalized children with gastroenteritis below 7 years old and determine the prevalence of enteric HAdV among all HAdV gastroenteritis. The study was conducted on 150 children below 7 years old. Antigen detection for rotavirus and HAdV by ELISA and determination of enteric HAdV (serotype 40 and 41) by nested PCR and restriction endonucleases study were performed. Detection of rotavirus and HAdV antigens in 150 stool specimens from patients with gastroenteritis were 58% (87), 6.7% (10), and 8% (12) positive for rotavirus, HAdV, and coinfection, respectively. Out of 22 HAdV antigen-positive cases, 15 cases were positive by PCR for enteric HAdV, with the prevalence rate of enteric HAdV gastroenteritis among all HAdV gastroenteritis cases of 68%, a serotyping study by PCR detected serotype 40 in 46.7% of cases (7/15) and serotype 41 in 53.3% of cases (8/15) with no statistically significant difference between them. The study confirmed that rotavirus and HAdV are prevalent etiological agents of diarrhea in children below the school-age group, highlighting the necessity of the rotavirus vaccine in addition to the obligatory schedule of vaccines in Egypt. Also, it determined that the enteric HAdV gastroenteritis prevalence rate was 68% among all HAdV gastroenteritis.
