Abstract

PURPOSE
The aim of this study was to evaluate thyroid dysfunction in obese children in Korea. METHOD: We measured body mass index and thyroid hormone in obese, overweight, and normal weight children who visited a pediatric clinic in Jeonju, Korea, from January 2009 to September 2012.
RESULTS
The free thyroxoine (FT4) level of the obese group (16.35 +/- 2.79 pmol/L) was lower than levels of the overweight (17.65 +/- 2.31 pmol/L) and normal weight (17.28 +/- 2.35 pmol/L; P=0.012) groups. The average value of FT4 in severely obese children (15.71 +/- 1.68 pmol/L) was lower than those of mildly and moderately obese children (16.40 +/- 2.88 pmol/L). We found no significant difference in thyroid stimulating hormone level between the obese group and normal weight group.
CONCLUSION
The FT4 level is lower in obese children than in normal weight children.
