Background Current literature suggests that diet is involved in either the development of premenstrual syndrome (PMS) or contributes to symptom severity, but to date, there are no studies evaluating eating attitudes of adolescents with PMS. The aim of this study was to evaluate dietary intake and eating attitudes in adolescents with PMS. Methods This study was conducted with 383 adolescents (214 with and 169 without PMS), aged 13-19 years. PMS was diagnosed using the premenstrual syndrome scale (PMSS). The Food Frequency Questionnaire (FFQ) and 24-h dietary recall were used to assess dietary intake. The Eating Attitudes Test-26 (EAT-26) and Three Factor Eating Questionnaire-Revised 18 (TFEQ-R18) were used to evaluate eating attitudes. Anthropometrical measurements and bone mineral content were measured. Results PMS prevalence was 55.9% according to PMSS subscales. Disordered eating attitudes determined by EAT-26 was detected in 23.8% in the PMS group and 11.8% of the control group (p<0.05). In the PMS group, total TFEQ-R18 score, emotional eating behavior and uncontrolled eating behavior scores were significantly higher (p<0.001). Whereas no significant difference in dietary intake, anthropometrical measurements or bone mineral content was observed between the two groups. Conclusions This is the first study documenting that not dietary intake but eating attitudes can be associated with PMS in adolescents. It is important to understand the relationship between disordered eating behaviors and PMS as both conditions may trigger the other.
