“…Previous studies have investigated the demographic profile of SS users, regarding sex and age [ 11 , 17 , 18 , 22 , 23 , 24 , 25 , 26 , 27 , 28 ]. These researchers have reported sex-based and age differences in the distinctive subpopulations studied [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 ]. Sex-based differences have been considered an important area of debate [ 25 , 32 , 33 , 34 ], where some authors have reported that men tend to use more SS [ 7 , 8 , 22 , 25 , 27 ], and others have suggested a greater prevalence of SS use in women [ 8 , 29 , 30 ].…”
