Purpose: To investigate 1) the association between television (TV) viewing and arterial stiffness (AS); and 2) whether any such association is independent of other lifestyle risk factors (RFs), most notably vigorous habitual physical activity (HPA), and/or is explained by TV-time-related adverse associations with biological RFs.
Methods: We investigated repeated measures (at ages 32 and 36) of TV time and other RFs among 373 subjects in whom stiffness of 3 large arteries was assessed with ultrasonography at age 36. Generalized estimating equations were used to determine the average differences in TV time between subjects across sex-specific tertiles (T1-3) of the inversed carotid, brachial and femoral distensibility (DC) and compliance (CC) coefficients, and the carotid Young’s elastic modulus (Einc).
Results: Compared with subjects in T1 (less stiff), those in T3 (stiffer arteries) of the carotid DC, CC and Einc spent more time (in min/day) [19.9 (95%CI:5.9;33.9), 16.7 (2.3;31.1) and 17.6 (3.7;31.5), respectively] on TV viewing during the 4 preceding years (Table, model 1). These differences were independent of vigorous HPA and other lifestyle RFs (model 2–3), and only in part (up to 31%) explained by TV-time-related associations with biological RFs (model 4). Qualitatively similar results were found for femoral, but not brachial, stiffness estimates.
Discussion: TV time is associated with higher levels of carotid and femoral stiffness in young adults, independently of HPA and other RFs. Promotion of more physical activity but also less sedentarism (two distinct behaviours) should, therefore, be encouraged to prevent AS and related sequelae.
