CHANGES IN RESPIRATORY INFECTION STATUS AND NUMBER OF DAYS ABSENT FROM SCHOOL DUE TO RESPIRATORY INFECTIONS AFTER PLASMA LC SUPPLEMENTATION IN CHILDREN AGED 6-9 YEARS OLD IN NINH BINH
Main Article Content
Abstract
Objective: To evaluate the effectiveness of Lactococcus lactis JCM 5805 supplementation on the incidence of respiratory and gastrointestinal infections and nutritional status in children aged 6-9 years” in 4 communes of Ninh Binh province. Methods: A placebo-controlled community trial to evaluate the effectiveness of improving respiratory tract infections after 8 weeks of using a product supplemented with Lactococcus lactis JCM 5805 (LC-Plasma) on 6-9 years old children in 4 communes of Ninh Binh province. There were 1,109 children 6-9 years old who satisfied the requirements, randomly divided into 2 groups of normal eating at home, the intervention group used products supplemented with Lactococcus lactis JCM 5805 (LC-Plasma) daily for 8 weeks, the control group was given a placebo. Results: the incidence, new incidence, number of episodes, number of days of illness, and incidence over time of respiratory infections in the intervention group tended to decrease compared with the placebo group, but there was no difference statistically significant difference between the 2 groups at the time after 4 weeks and after 8 weeks of intervention. The cumulative number of days of fever, cough, and runny nose in the 8 weeks of the intervention group was lower than the number of days in the placebo group (p<0.05). The number of days absent from school due to respiratory infections in the intervention group (33 days) was lower than the number of days absent in the placebo group (62 days) (p<0.01). Conclusion: Using a product containing 50mg Lactococcus lactis JCM 5805 (LC-Plasma) 7 days a week for 8 weeks has improved the cumulative number of days of respiratory infections, the cumulative number of days of absence from school due to infection respiratory bacteria in children 6-9 years old in Ninh Binh.
