摘要: ObjectiveTo assess the effectiveness of multiple cleaning and disinfection interventions in the homes and kindergartens, in reducing gastrointestinal and respiratory illnesses of children.
MethodsFrom October 2010 to September 2011, we performed a prospective, controlled study in China. 408 children under 5 years old were recruited and group randomized into intervention and control groups. Families and kindergartens in the intervention group were provided with antibacterial products for hand hygiene and surface cleaning or disinfection for one year. Each child’s illness symptoms andsick leave were recorded every day.
ResultsA total of 393 children completed the study, with similar baseline demographics in each of the 2 groups.Except for abdominal pain, the odds of symptoms(fever, cough and expectoration, runny nose and nasal congestion, diarrhea), illness (acute respiratory illness and gastrointestinal illness), and sick leave per person each month were significantly reduced by interventions. The rates of fever, diarrhea, acute respiratory illness, gastrointestinal illness and sick leave per person per year were significantly decreased as well.
ConclusionNot only the acute respiratory and gastrointestinal illness but the sick leave rate in children were significantly reduced by multiple interventions.
