6 - Which statement is true:

C   - Underweight girls and not boys who inaccurately assessed their weight had higher odds of extreme weight management practices
D   - This study shows higher odds of extreme weight management practices among underweight boys who over-assess their weight thereby supporting recommendations to screen underweight boys (as has been done with underweight girls)
