Abstract
Objective: To investigate differences in dietary intake variables and anthropometric measurements in healthy young adult women of healthy body mass index (BMI) with high and low scores of cognitive eating restraint (CER), disinhibition (DI), and hunger.

Design: Cross-sectional study in which the Eating Inventory was completed along with the Block Food Frequency Questionnaire and anthropometric measurements using standard procedures and dual-energy X-ray absorptiometry, respectively.

Participants: 65 healthy young adult women.

Setting: This research was conducted in the Bone Laboratory on the campus of the Virginia Polytechnic Institute and State University, Blacksburg, Virginia.

Statistical analyses: Independent t-tests, Pearson correlation coefficient analyses, and general linear regression models.

Results: Women with high CER scores (n=32; mean±SD CER score=13.1±2.4) consumed more fruits per day (2.4±0.9 svg/d) compared to women with low CER scores (n=33; CER score=4.5±3.0; fruits=1.8±1.1 svg/d; p<0.05). Women with high hunger scores (n=35; hunger score=7.5±2.2) consumed less fruits per day (1.8±0.9 svg/d) compared to women with low hunger scores (n=30; hunger score=3.0±1.1; fruits=2.4±1.1 svg/d; p<0.05). Women with high compared to low CER scores had higher body weight (p<0.05), BMI (p<0.05), fat mass (p<0.05), and body fat percentage (p<0.05), while women with high (n=31; DI score=7.6±2.5) compared to low (n=34; DI score=2.9±1.0) DI scores were taller (p<0.05). Hunger predicted estimated daily dietary intakes of total energy (p<0.05), protein (p<0.01), and fat (p<0.01), while CER (p<0.05) and DI (p<0.05) predicted estimated daily dietary fruit intake.

Conclusion: In healthy young adult women, eating characteristics can distinguish between some dietary intake patterns and anthropometric measurements. Hunger is a predictor of estimated energy, protein, and fat intake in these women.
