A total of 752 adolescent girls aged 12-18 years wererecruited from several schools by using a random cluster sampling method. A valid andreliable food frequency questionnaire (FFQ) was used to obtain the dietary intakes ofthe girls.

Results: Three major dietary patterns wereidentified based on the principal component analysis (PCA), including healthy, western,and traditional dietary patterns. No significant associations were found between thequartiles of healthy (OR: 1; 95 CI 0.62-1.59, P trend = 0.75), western (OR: 1.3; 95CI 0.8-2.10, Ptrend= 0.16) or traditional (OR: 0.62; 95 CI 0.69-1.82, Ptrend = 0.64)dietary patterns and sleep insomnia. In addition, there were no significant relationshipsbetween the quartiles of healthy (OR: 0.85; 95 CI 0.54-1.69, P trend = 0.84), western(OR: 0.81; 95 CI 0.49-1.32, Ptrend = 0.55) or traditional (OR: 1.07; 95 CI 0.66-1.74,Ptrend = 0.9) dietary patterns and daytime sleepiness.
