Why would anyone take the A4 skinny waist challenge?

The #A4waist challenge - in which women compare the size of their waists to the width of a standard A4 sheet of paper - started in China and prompted a huge online backlash. But what do some of the women who participated in the trend say - why did they take part?
It's been criticised as irresponsible and potentially unhealthy. The latest craze from China involves mostly women holding up sheets of paper and taking selfies - they "win" if the paper entirely obscures their waist. It's called the "A4 challenge" after the standard paper size that's just 21cm (8.3in) across.
