  1. Body mass index (BMI). Age, in years, as a continuous variable (Age). Age, in years, defined as under 65, or 65 and over, as a binary variable (Age ≥ 65). Serotonin-transporter-linked polymorphic region alone (5-HTTLPR); or combined with rs25531 SNP (5-HTTLPR + rs25531). Intron 2, 17 bp variable number of tandem repeats (STin2 VNTR); allelic model definitions described in Supplementary Table 2. Recessive allele (rec); dominant allele (dom). Text in bold indicates covariates included in the forward conditional regression model.
