Both　telomere　length　and　alcohol　consumption　have　an　important　impact　on　biological　age　and　carcinogenesis.　Researchers　have　conducted　many　efforts　to　study　the　relationship　between　alcohol　consumption　and　telomere　length　yet　reached　no　consensus.　In　this　paper,　a　meta-analysis　is　performed　and　relevant　investigation　results　from　previous　literature　are　integrated.　Twenty-one　works　of　literature　published　between　2000　and　2016,　which　comprise　27　analyses　with　a　total　samples’　size　of　35,891,　meet　our　screening　conditions.　Whether　the　relationship　between　alcohol　consumption　and　telomere　length　is　significant,　this　issue　varies　with　study　type　(cohort,　case-control,　or　cross-sectional)　and　study　population　(Europe,　Asia,　American,　or　Australia).　It　is　deduced　by　combined　evidence　that　alcohol　consumption　is　associated　with　telomere　length　(with　Fisher’s　combined　p-value　=　3.52E-8　and　Liptak’s　weighted　p-value　=　8.24E-3).　In　the　future,　the　consistent　standardised　quantifications　of　alcohol　consumption　and　telomere　length　will　avail　further　aggregation　of　the　evidence　from　various　studies.　Copyright　©　2021　Inderscience　Enterprises　Ltd.
