Background & Aim: Bisphenol A (BPA) is a chemical substance used extensively world-wide in the manufacture of plastic
polymers. The environmental obesogen hypothesis suggests that early life exposure to endocrine disrupting chemicals such as
BPA may increase the risk for weight gain later in childhood. Recent reports stated that infants and children are mostly exposed
to BPA due to higher usage of plastic materials for food and drinks packaging and toys. Aim of this study is to find the relation
between BPA and obesity among Egyptian children.
Methods: BPA concentrations were measured in randomly collected urine samples of 297 Egyptian children 2-18 years old
of different social levels. Weight and height had been measured for all and the BMI had been calculated and correlated to the
urinary BPA concentration.
Results: The mean LOG total BPA in obese children (-0.28�±0.44 ng/ml) was significantly lower than that in non-obese
children (-0.12�±0.47 ng/ml) (p=0.047) and the mean LOG of adjusted BPA/gm of creatinine in obese children (2.44�±0.53) was
significantly lower than that in non-obese children (2.72�±0.53) (p=0.004). Also, correlations of total, conjugated, unconjugated
and log urinary BPA concentrations/gm of creatinine with indicators of obesity. Only the adjusted log transformed urinary
BPA level/gm of creatinine shows highly significant negative correlation with obesity indices including BMI-z score, waist
circumference and hip circumference (r=-.257, p=.002; r=-.267, p=.001; and r=-.281, p=.001 respectively). No significant
difference could be detected between obese and non-obese children as regard BPA.
Conclusion: Exposure to BPA as measured by total urinary BPA concentration was not a risk factor for obesity.
