Objective: To determine if vitamin D intake is associated with acute lower respiratory infections (ALRI) in children.
Methods: The vitamin D intakes of children younger than 5 years of age admitted to hospital with either bronchiolitis or pneumonia were compared to an unmatched control group of the same age without respiratory infection.
Caregivers of 197 children completed a questionnaire collecting information on demographic variables, ALRI risk factors and diet.
Associations of ALRI with vitamin D intake and other ALRI risk factors were determined.
Results: The mean vitamin D intake of children with ALRI was 48 IU/kg/d compared to 60 IU/kg/d in the control group.
When controlling for age, ethnicity, socio-economic status, northern residence, breastfeeding, immunizations and smoking contact, children with a vitamin D intake of less than 80 IU/kg/d were greater than 4 times more likely to have ALRI compared to children with a vitamin D intake exceeding 80 IU/kg/day (OR 4.9 , CI: 1.5, 16.4).
Conclusions: A higher vitamin D intake than currently recommended might be needed to offer protection against diseases such as ALRI.
Increased vitamin D supplementation could have important public health consequences, as bronchiolitis and pneumonia are the most common reasons for hospitalization in young children.

Very pleased to see that this study considered how much vitamin D the child was taking vs weight
various groups, such as in Poland recommend 100 IU/kg daily
