A blog to promote debate and discussion around current issues of interest to the network. David MacKintosh, one of the founders of the network, writes a weekly blog piece, all editions of which can be found here. We also invite contributions to the blog from others with ideas and opinions on issues relating to health behaviours and urban health and wellbeing. If you would like to contribute, please send your post to us for consideration at [email protected] - if accepted for publication, your blog will be posted here on the GPHN website, as well as being included in the weekly GPHN alerts sent to all those in the network.
