st: ANOVA for quartiles

Dear Statalisters,
I intend to perform an ANOVA to compare the means of a variables across quartiles of BMI ( body mass index) in two genders (male and female ).
Example: Male Female
BMI Q1 : 5.2 5.1
BMI Q2 : 5.6 5.4
BMI Q3 : 6.3 6.8
BMI Q3 : 7.7 7.9
I want to compare these values across the quartiles using ANOVA, and look for significance in both genders separately.
bysort bmi_quartiles gender : oneway bmi
There seems to be something wrong in this script. I am quite naive to STATA and not sure as to how to go about with this.
Advice of any sort will be very helpful.
Best regards,
