WENDY Study: Investigating Gynecological and Metabolic Health in Women Aged 33-37

Overview

The WENDY study is a large, population-based cohort study conducted in Finland involving 1918 women aged 33 to 37. It comprehensively assesses gynecological and metabolic health through clinical measurements, biological samples, ultrasound, questionnaires, and mobile app follow-up, with data linkage to national registers and birth cohort data.

Background

Gynecological conditions such as heavy menstrual bleeding, PCOS, and endometriosis significantly impact women's quality of life but are often underrecognized and diagnosed late. Metabolic disorders increasingly affect gynecological health, highlighting the need for integrated research. Previous cohort studies have not focused extensively on gynecological and metabolic health combined or allowed extensive register linkage from birth onward. The WENDY study addresses these gaps by providing a unique, comprehensive data set to improve understanding and diagnostics in women's health.

Data Highlights

Key Findings

• The study included 1918 women aged 33-37, with 81% from the Northern Finland Birth Cohort 1986.
• Data collection involved clinical exams, biological samples, ultrasound, extensive questionnaires, and mobile app follow-up for menstrual cycle and cognitive testing.
• 98% of participants consented to linkage with Finnish national registers, enabling comprehensive longitudinal analyses.
• The cohort data can be linked from fetal stage through adulthood, providing a unique life-course perspective on gynecological and metabolic health.
• The study addresses gaps in recognition and diagnosis of gynecological conditions by integrating metabolic and reproductive health data.

Clinical Implications

The WENDY study's comprehensive data set enables improved understanding of the prevalence and impact of gynecological and metabolic conditions in women during their fertile years. Clinicians can leverage these insights to enhance early diagnosis, tailor interventions, and promote health awareness. The linkage to national registers and longitudinal data supports development of novel diagnostic tools and targeted therapies.

Conclusion

The WENDY study represents one of the largest and most detailed population-based investigations into women's gynecological and metabolic health, offering valuable data to improve diagnostics, treatment, and health outcomes for women in mid-adulthood.
