Nutrient Intake and Menopausal Symptoms in Perimenopausal Women

Perimenopause, the final years of a woman's reproductive life, may be symptomatic, affecting health and wellbeing. Lifestyle factors, such as diet, may alleviate these symptoms and improve health. Understanding nutrient intake at this stage of life is critical for tailoring dietary recommendations. This study investigated the nutrient intake of perimenopausal women in relation to adult guidelines and explored the associations between nutrients and symptoms.

Irish perimenopausal women were recruited (>40 years old). Participants reported symptom severity via the Menopause Rating Scale (MRS). They completed a 4-day food diary along with a physical activity (PA) and demographic questionnaire. Hierarchal multiple regression was used to test the relationship between MRS and nutrients. A one-sample t-test or Wilcoxon signed-rank test was used to compare nutrient intake to the guidelines.

Participants (n = 63) had a mean age of 47.8 ± 3.5 years, a body mass index (BMI) of 27.0 ± 3.9 kg/m² and an overall MRS score of 13.5 ± 6.9. Participants were not meeting dietary reference values (DRVs) for most nutrients, with intakes significantly below guidelines for fibre (p < 0.001), total vitamin D (p = 0.031), calcium (p < 0.001), and iron (p < 0.001), and exceeding guidelines for saturated fat (p < 0.001). Hierarchal multiple regression models (adjusted for BMI, age, marital status, and PA) showed that Vitamin E intake was a predictor of a higher urogenital sub-score (β = 0.405, p < 0.001).

There was variable adherence amongst midlife women to dietary guidelines, which may impact on both current and future health status. Public health initiatives are required to address this.
