Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder characterized by reproductive and metabolic abnormality disorders. Dietary factors influence the body composition and hydration status, which may exacerbate PCOS symptoms. The aim of this study was to assess the associations between the habitual nutrient intake and bioelectrical impedance analysis parameters in Polish women with PCOS and healthy controls, in order to identify potential nutritional targets for a non-pharmacological intervention. This study involved 50 women aged 18-45 years (25 with PCOS and 25 healthy). Participants kept 7-day food diaries and their body composition was assessed using the SECA mBCA 515 analyzer. The nutrient intake was compared with EFSA recommendations. Women with PCOS had a higher body weight, waist circumference and body mass index, visceral adipose tissue, and fat mass index, despite no difference in their total energy intake. They consumed more omega-3 fatty acids (EPA + DHA) than the control group. Vitamin D deficiency and irregular supplementation were common in both groups. Body composition parameters such as the phase angle and ECW/TBW ratio correlated with the diet quality-especially with protein; fiber; and vitamin B2, B12, and folate levels. The obtained results showed significant differences in body compositions and the presence of a relationship between the nutrient intake and bioimpedance parameters in women with PCOS. These results emphasize the importance of a comprehensive nutritional and body composition assessment in planning dietary interventions in this group of patients.
多囊卵巢综合征（PCOS）是一种常见的内分泌和代谢紊乱疾病，其特征为生殖和代谢异常紊乱。饮食因素会影响身体成分和水合状态，这可能会加重PCOS症状。本研究的目的是评估波兰PCOS女性和健康对照者的习惯性营养素摄入量与生物电阻抗分析参数之间的关联，以便确定非药物干预的潜在营养靶点。本研究纳入了50名年龄在18至45岁之间的女性（25名患有PCOS，25名健康）。参与者记录了7天的饮食日记，并使用SECA mBCA 515分析仪评估了她们的身体成分。将营养素摄入量与欧洲食品安全局（EFSA）的建议进行了比较。尽管PCOS女性的总能量摄入量没有差异，但她们的体重、腰围、体重指数、内脏脂肪组织和脂肪质量指数更高。她们摄入的ω-3脂肪酸（EPA + DHA）比对照组更多。两组中维生素D缺乏和补充不规律的情况都很常见。身体成分参数，如相位角和细胞外液/总体液比值，与饮食质量相关，尤其是与蛋白质；纤维；以及维生素B2、B12和叶酸水平相关。获得的结果显示，PCOS女性的身体成分存在显著差异，且营养素摄入量与生物阻抗参数之间存在关联。这些结果强调了在为这组患者制定饮食干预计划时，进行全面营养和身体成分评估的重要性。
