Ethics approval and consent to participate

: The SHIP-1 data were requested from the Community Medicine Research Alliance of the University Medicine Greifswald. SHIP-1 was approved by the ethics committee of the University Medicine Greifswald (registration number: III UV 73/01).The approval and the handover of the SHIP-1 data through the Community Medicine Research Alliance include the consent for publication as long as data protection is respected. For the representation of the participants’ residences on the maps, the geographical coordinates of the participants were spatially noised to preclude identification of individual participants. After performing the network analyzes, random numbers are generated and added or subtracted to the exact x and y coordinates to pseudonymize the geographic coordinates. This produces incorrect coordinates which lie in a square of 50 m edge length. Therefore, the identification of the participants’ addresses is not possible.
