Influence of Probiotics on Atopy With Focus on Respiratory Allergic Diseases- Follow-up to 7 Years

The investigators had conducted an initial double-blind, placebo-controlled clinical trial (NCT00318695) to study the effects of probiotic supplementation from birth to 6 months of age in the incidence of atopic diseases at 2 years old. This is then further investigated up to 5 years of age in a follow-up study NCT00365469 to assess the longer term beneficial effects. This current study intends to follow-up for another 2 years until 7 years of age as this is critical in the evaluation of respiratory allergies in the form of clinical asthma and allergic rhinitis.
