Study design and participants
The data reported are from the cross-sectional, observational study, Estrogenic Regulation of Muscle Apoptosis (ERMA) (data set: https://doi.org/10.17011/jyx/dataset/83491). The study data collection has been described in detail in Kovanen et al.10 Briefly, out of the 6 878 randomly selected women aged 47 to 55 years living in Central Finland, 3 064 women returned written consent and prequestionnaire that included questions on symptoms of pelvic floor disorders. Exclusion criteria included conditions or use of medications affecting ovarian function, self-reported body mass index [BMI] > 35 kg/m2, and medications or symptomatic diseases affecting muscle functions. From the eligible participants, 1 393 gave fasting blood samples and 1 102 of them answered to the main questionnaire survey that included eating behaviour questions. Four questionnaires were lost due to technical errors. Therefore, the final sample size of the present study is 1 098. The study was conducted according to the Declaration of Helsinki and was approved by the Ethics Committee of the Central Finland Health Care District (KSSHP Dnro 8U/2014) before the onset of data collection.
