RT Journal Article T1 Residential surrounding greenspace and age at menopause: A 20-year European study (ECRHS) A1 Triebner, Kai A1 Markevych, Iana A1 Hustad, Steinar A1 Sánchez Ramos, José Luis AB Background: Menopause is associated with a number of adverse health effects and its timing has been reported tobe influenced by several lifestyle factors. Whether greenspace exposure is associated with age at menopause hasnot yet been investigated.Objective: To investigate whether residential surrounding greenspace is associated with age at menopause andthus reproductive aging.Methods: This longitudinal study was based on the 20-year follow-up of 1955 aging women from a large, population-based European cohort (ECRHS). Residential surrounding greenspace was abstracted as the average ofsatellite-based Normalized Difference Vegetation Index (NDVI) across a circular buffer of 300m around theresidential addresses of each participant during the course of the study. We applied mixed effects Cox modelswith centre as random effect, menopause as the survival object, age as time indicator and residential surrounding PB Elsevier SN 0160-4120 YR 2019 FD 2019-08 LK http://hdl.handle.net/10272/16687 UL http://hdl.handle.net/10272/16687 LA eng NO Triebner, K., Markevych, I., Hustad, S., Benediktsdóttir, B., Forsberg, B., Franklin, K.
