Flo Health Validates Perimenopause Symptom Scale in Clinical Study

Flo Health

Flo Health’s Perimenopause Symptom Scale (Peri-SS) has been validated as a reliable tool for assessing perimenopause symptoms, according to a new study published in Menopause.

The study included 1,255 American women ages 35 to 59 and evaluated the 16-item digital self-assessment tool, co-developed by Flo Health and Mayo Clinic, for its ability to identify and measure symptom severity.

During the validation study, women used Peri-SS to track the occurrence and severity of sexual, physical, psychological, and vasomotor symptoms. Responses were evaluated against established questionnaires, including the Menopause Rating Scale (MRS) and EuroQol 5-Dimension, 5-Level questionnaire (EQ-5D-5L), to assess the tool’s efficacy and usability. 

Flo Health uses the results to generate a personalized Peri Score, helping users understand the impact of their symptoms and track how they change over time.

“We are only now beginning to understand the ways perimenopause can impact a woman’s life, and the validation of the Peri-SS gives us a powerful, research-backed tool to more effectively assess symptom severity,” said Dr. Liudmila Zhaunova, Flo Health’s Director of Science and a lead author of the study. 

The findings add to growing efforts to develop standardized, research-backed tools for identifying and assessing perimenopause symptoms.
