Optimal nutritional intake plays a role in hormone activity, including reducing the incidence of premenstrual syndrome. This study aims to determine the relationship between percent body fat, adequate intake of carbohydrates, protein, and calcium on the incidence of premenstrual syndrome.

Data analysis using Spearman Rank Test.

Result: There was no correlation between body fat percentage and incidence of premenstrual syndrome (p>0,05). There was no correlation between adequate carbohydrate intake and the incidence of premenstrual syndrome (p>0,05). There was no correlation between adequate protein intake and the incidence of premenstrual syndrome (p>0,05). There was no correlation between adequate carbohydrate intake and the incidence of premenstrual syndrome (p>0,05).

Conclusion: There are no corellation between body fat percentage, adequate intake of carbohydrates, protein, and calcium on the incidence of premenstrual syndrome.
