Table 2 List of the 40 examined traits available in the UK Biobank. Each lifestyle indicator of interest from UK Biobank participants is shown alongside its field identification number. Each indicator was analyzed in two groups according to sex. All indicators were divided into one of three categories, defined by traits related to regular social interaction (social domain), traits related to personality (personality domain), and traits related to demographic standing and environment (demographic domain).
