A study conducted by the College of Medicine, National Cheng Kung University, Taiwan, and published in the January 2012 journal of Clinical and Developmental Immunology “aimed to examine the association between the length of use of feeding bottles or pacifiers during childhood and the prevalence of respiratory and allergic morbidities. A large-scale questionnaire survey was performed in day care centers and kindergartens (with children’s ages ranging from 2 to 7 years) in southern Taiwan, and a total of 14,862 questionnaires completed by parents were finally recruited for data analysis.”  This is the first study that shows the potential risk  of using plastic products and their effects on the health of young children in Asian countries, and that ” a longer period of use of feeding bottles indicated a higher risk of diseases/symptoms among preschool children after adjustment for various confounders, including the children’s age, gender, gestational age, birth weight, length of time being breastfed, the age first given infant formula or complementary foods, family history, parental educational levels, and smoking status, as well as the problem of indoor water damage.”  To read the study, click here.
