Eating behavior: The influence of age, nutrition knowledge, and Mediterranean diet.

BACKGROUND

Student life during the university period is characterized by many changes in eating behaviors and dietary patterns due to adaptation to a new environment, study stress, lack of proper time management, and busy class schedules. These unhealthy actions may be detrimental to cognitive processing and influence academic performance, which is related to professional success.

AIM

To assess different eating patterns in Portuguese university students and relate them to several sociodemographic variables.

METHODS

Cross-sectional information about eating behavior was assessed using the Dutch Eating Behavior Questionnaire in 169 students between 18 and 50 years of age, from the and from different academic courses, some related to health sciences. Mediterranean diet adherence was also assessed using a validated 14-item questionnaire.

RESULTS

According to the analyses of the 169 participants included in the sample, 33 presented restrained eating behavior, with 73 presenting external and 63 emotional. In the same line of thought, 62.10% of nutrition sciences students presented emotional eating behavior and overall it was observed that these students were more likely to have emotional eating behavior. Otherwise, presenting restrained eating behavior was statistically associated with being older and having higher Mediterranean diet adherence.

CONCLUSIONS

Studying nutrition sciences was associated with having emotional eating behavior. Older students and those who adhere more closely to the Mediterranean diet were associated with having restrained eating behavior.
