Structured physical activity resulted in a significantly lower likelihood of having poor sleep quality ( adjusted odds ratios ( aOR ) for PSQI > @ = @ , @ % confidence interval ( CI ) = @-@ @ ) , including fewer new cases ( aOR for PSQI > @ = @ , @ % CI = @-@ @ ) , than health education but not in resolution of prevalent cases ( aOR for PSQI @ = @ , @ % CI = @-@ @ ) .
