To study the relationship between adenoid hypertrophy, tonsillar hypertrophy and overweight or even obesity in children.

A total of 799 children aged 2 to 12 years with tonsillar and adenoid hypertrophy from January 2015 to December 2019 in the Department of Otolaryngology Head Neck Surgery, the Sixth Medical Center of Chinese PLA General Hospital were selected. The body mass index (BMI) was calculated according to the height and weight measured routinely at the time of admission. The difference of BMI between children and normal children of the same age, and the correlation between adenoid, tonsil hypertrophy and obesity were compared. Chi-square test was used to compare the surgical children′s BMI of different genders with normal children of the same age, and Spearman rank correlation was used to analyze the correlation between BMI and adenoid and tonsil hypertrophy.

The Spearman correlation coefficient between tonsil hypertrophy and BMI was 0.078, P=0.077, the Spearman correlation coefficient between adenoid hypertrophy and BMI was -0.058(P=0.100). χ ² test showed that the proportion of overweight and obesity in school-age children (7~12 years old) was significantly higher than that in preschool children (2~6 years old), and the difference was statistically significant (χ²_male=22.386, P_male<0.001, χ²_female=4.478, P_female<0.001).

There is no obvious correlation between adenoid hypertrophy, tonsil hypertrophy and overweight or obesity in children, but the probability of children overweight or obesity increases with age, and the proportion of obesity in children aged 7-12 years is higher.
