Abstract :
Background: Phthalates are a group of environmental endocrine disruptors and have been ubiquitously applied in
industrial field. Few studies had investigated how dietary intake was related with phthalate body burden in children.
To determine the relationship between phthalate body burden and dietary intake among school age children in
Shanghai, China.
Methods: Four hundred and thirty schoolchildren aged 8–16 years were recruited in a cross-sectional study with
18 months follow-up in Shanghai, China during 2010–2012. Data of questionnaire-based dietary intake were collected
and urinary phthalate concentrations were measured. Associations between frequency of dietary intake and phthalate
metabolite concentrations were evaluated by stepwise multiple linear regression model.
Results: Positive association was found between mono-butyl phthalate and seafood, and negative associations were
found between mono-butyl phthalate and dried fruits and vegetables. Egg consumption showed negative association
with all di-(2-ethylhexyl) phthalate-related metabolites.
Conclusions: Some food types were identified to be associated with phthalate body burden and diet might be a
source of phthalate exposure among Chinese schoolchildren.
