Objective. To evaluate the nutritional status of children from 12 to 36 months of age in Kimdong, a rural district in Hungyen Province, Northern Vietnam, in 2017. Subjects and Methods. A cross-sectional study was carried out on 327 children aged 12-36 months. The data collected included anthropometric measurement, serum hemoglobin (Hb), and vitamin D concentration. Blood analysis was done at the Center Laboratory of Hungyen Obstetrics and Pediatrics Hospital. Underweight, stunted, and wasted children were classified based on z-scores cut-off less than -2 SD of weight for age (WAZ), height for age (HAZ), and weight for height (WHZ), respectively. Overweight and obese children were defined if WHZ was more than + 2SD. Anemic child was applied when Hb concentration was less than 110 g/L while vitamin D deficiency was termed for level less than 20 ng/L. Results. The prevalence of underweight, stunted, wasted, and overweight/obese children was 7.6%, 23.5%, 6.7%, and 1.2%, respectively. The prevalence of anemia and vitamin D deficiency was 33.3% and 47.7%, respectively. Malnutrition, anemia, and vitamin D deficiency were not statistically different by sex. Malnutrition and vitamin D deficiency were not statistically different by age group but anemia by age groups was significantly different. Conclusions. Stunting is still prevalent in children aged 12-36 months in Kimdong. Moreover, anemia and vitamin D deficiency also affected children in this area. Some interventions should be conducted to improve the nutritional status of children in Kimdong district.

Mục tiêu: Nghiên cứu nhằm mô tả đặc điểm lâm sàng, cận lâm sàng của 81 trẻ gái dậy thì sớm trung ương (DTSTƯ) tại Bệnh viện Trẻ em Hải Phòng từ tháng 1 năm 2018 đến tháng 10 năm 2019. Đối tượng và phương pháp nghiên cứu: Đối tượng nghiên cứu gồm 81 trẻ gái được chẩn đoán là DTSTƯ. Phương pháp nghiên cứu mô tả một loạt ca bệnh. Các trẻ gái được lựa chọn vào nghiên cứu theo phương pháp thuận tiện không xác suất. Kết quả nghiên cứu: Phần lớn (61,73%) dậy thì sớm phát hiện khi trẻ được 6-8 tuổi với lý do đến khám bệnh là vú to (82,71%) và có kinh nguyệt dưới 3 tháng. 100% đối tượng có tuyến vú giai đoạn Tanner 2 trở lên, 16,05% có lông mu, 11,11% có kinh nguyệt và chiều cao tăng thêm 2,05 ± 0,98 cm. Đối tượng có tuổi xương lớn hơn tuổi thực trung bình tại thời điểm khám bệnh là 21,9 ± 2,71 tháng. Hơn một nửa (55,56%) trẻ gái có chiều cao tử cung trên 34 mm. Hầu hết (87,7%) trẻ được làm test GnRH, 100% các trường hợp LH < 0,3 UI/L đều được làm test GnRH. 100% các trường hợp nghiên cứu của chúng tôi là dậy thì sớm trung ương vô căn. Kết luận: Trẻ gái DTSTƯ thường xuất hiện 6-8 tuổi biểu hiện vú to và kinh nguyệt. Tuổi xương cao hơn tuổi thực, bề cao tử cung trên 34 mm, thường vô căn.

Introduction. Acute diarrhea caused by group A rotavirus (RVA) is a leading cause of morbidity and mortality globally in children less than 5 years old. Acute diarrhea caused by RVA is often manifested by loose/watery stool leading to different degrees of dehydration. The detection of risk factors, diagnosis, and prompt treatment of acute diarrhea caused by RVA is critical. We aimed to describe clinical epidemiological features of acute diarrhea caused by RVA and its associated risk factors. Subjects and Method. We conducted a cross-sectional study that included 321 children under 5 years old with acute diarrhea at Haiphong Children’s Hospital, Vietnam, from 1 August 2019 to 31 July 2020. Results. Among the 321 children included in our analysis, 221 (68.8%) children were positive for RVA. Males represented 61.1% of cases, 41.2% of children were in the 12-<24-month age group, and the majority of cases were among children in suburban areas (71.5%). Clinical manifestations included loose and watery stool (100%), vomiting-fever-loose/watery stool (57.9%), vomiting-loose/watery stool (83.2%), fever-loose/watery stool (58.8%), dehydration (30%), hyponatremia (22.1%), hypernatremia (1.4%), and hypokalemia (15%). Risk factors for acute diarrhea caused by RVA included history of diarrhea, not exclusive breastfeeding in the first 6 months, living area, maternal education, and income. Conclusions. Acute diarrhea due to RVA was very prevalent in children under 5 years old. Clinical manifestations included a high prevalence of loose/watery stools/day and dehydration with electrolyte disorder. Mothers should exclusively breastfeed their children for the first 6 months to avoid the risk of acute diarrhea caused by RVA.
