Who is at low risk for cardiovascular disease ? An assessment of different definitions . BACKGROUND There is little information regarding the determinants and trends of the prevalence of low cardiovascular risk factor ( RF ) profile in the general population . The aim of this study was to assess the prevalence and trends of low RF profile in the Swiss population according to different definitions . METHODS Population-based cross-sectional studies conducted in 1984-1986 ( N=3300 ) , 1988-1989 ( N=3331 ) , 1992-1993 ( N=3133 ) and 2003-2006 ( N=6170 ) and restricted to age group 35-75 years . Seven different definitions of low RF profile were used to assess determinants , while two definitions were used to assess trends . RESULTS Prevalence of low RF profile varied between 6.5 % ( 95 % confidence interval : 5.9-7.1 ) and 9.7 % ( 9.0-10.5 ) depending on the definition used . This prevalence was higher than in other countries . Irrespective of the definition used , the prevalence of low RF profile was higher in women and in physically active participants , and decreased with increasing age or in the presence of a family history of cardiovascular disease . Using one definition , the prevalence of low RF profile increased from 3.8 % ( 3.1-4.5 ) in 1984-1986 to 6.7 % ( 6.1-7.3 ) in 2003-2006 ; using another definition , the results were 5.9 % ( 5.1-6.8 ) and 9.7 % ( 9.0-10.5 ) , respectively . CONCLUSION Switzerland is characterized by a high and increasing prevalence of low RF profile within the age group 35 to 75 , irrespective of the criteria used . This high prevalence might partly explain the low and decreasing trend in cardiovascular mortality rates .
