Objective To determine the effect of asthma on bone mineral density (BMD) in children who were newly diagnozed. Methods A total of 190 children with asthma at the beginning of treatment were collected from our respiratory department during May 2010 to June 2011. Their height and weight were mea-sured and recorded
and BMD was measured with ultrasound bone analyzer. The results were compared with those of 166 healthy children at the same age in the
Child Health Clinic of our hospital in the same period. Results 95% confidence interval (95%
CI
) of Z-Score in the asthma group was lower than in control group
with significant difference (
t
=7.229
P
=0.000). There was significant difference in the speed of sound (SOS) between the asthma group and control group (
F
=20.040
P
=0.000). SOS value of moderate and severe asthma group was lower than that of mild group (
P
<
0.05)
which had no significant difference with that of control group (
P
=0.410). There was no difference between moderate and severe asthma groups (
P
=1.000). The course of asthma was negatively correlated with BMD (
r
=-0.442
P
<0.01). Compared with the control group
the value of height and weight in asthma group was decreased at different degrees. The value of height and weight was significantly lower in severe group than in mild-moderate group and control group (
P
<
0.05). Conclusion Asthma may have influence on children’s height
