Limitations and Strengths
The present study had some limitations, as well. In addition to the lack
of generalizability, this study had a cross-sectional approach; then, no
causal relationships could be established among variables. Moreover,
polysomnographÂic recordings were not applied due to restrictions in
funding. Despite these limitations, this was the first study that
evaluated the associations of the DII scores with obesity and sleep
quality in young Iranian female. Moreover, we examined the Association
between DII score and anthropometric variables and PSQI score using
linear regression analysis and multivariable logistic regression in 3
different models.
