Methods Infants aged 0-3 months who took physical examination were investigated from January 2019 to January 2020.Because of the difference on the standards for body length, weight, speed of sound (SOS) between boys and girls, the research objectives of different genders were compared seperately.According to the 2006 WHO Child Growth Standards, research objectives were divided into overweight group and normal group.The level of BMD between overweight group and normal group was compared.Then, the BMD level was compared between different genders in each group. Results There were no significant differences on the level of SOS between overweight group and normal group in boys and girls (P>0.05).Z value did not showed significant differences between boys and girls in overweight group and normal group (t=-1.23, -0.47,P>0.05). Conclusions No significant correlation has been found between overweight and BMD in 0 to 3-month-old children.However, further studies are warranted to explore the relationship between various influencing factors and BMD or between aging and BMD, thereby providing better guidance for clinical practice. %U https://manu41.magtech.com.cn/Jwk_zgetbjzz/EN/10.11852/zgetbjzz2020-0261
