Book of abstracts of the 6th CHRC Annual Summit

Dear Editor, I am enclosing a submission to the Portuguese Journal of Public Health entitled “Book of abstracts of the 6th CHRC Annual Summit”. This manuscript is intended to integrate a Supplement Issue especially dedicated to the 6th CHRC Annual Summit. This paper consists of 76 abstracts that have been presented at the Annual Summit on September 22nd and 23rd, 2025. All the abstracts passed through a double-blind review process performed by the Summit Scientific Committee, and only accepted abstracts were presented are in this book of abstracts. The Manuscript consists of a manuscript with 76 pages. All the abstracts are separated by a page break and sequentially ordered. The book of abstracts contains original data that have not previously been published, at least that was the commitment made by the authors. The editorial board declare there is no conflict of interest. I assume responsibility for keeping my co-authors from the editorial board informed of our progress through the editorial review process. Yours faithfully, Corresponding author: Jorge Bravo
