Maximum carotid and aortic intima-media thickness and brachial artery flow-mediated dilation were measured in 494 adolescents using high-resolution ultrasound. Serum lipid, lipoprotein, and apolipoprotein (Apo) A-I and B concentrations were determined using standard methods. Exposure to tobacco smoke was measured annually between ages 8 and 13 years using serum cotinine concentrations, analyzed with gas chromatography. To define longitudinal exposure, cotinine values of children having serum cotinine measured 2 to 6 times during follow-up were averaged and divided into tertiles (exposure groups): low (n=160), intermediate (n=171), and high (n=163). Adolescents with higher longitudinal exposure to tobacco smoke had increased carotid intima-media thickness (exposure groups [mean\u00b1SD]: low, 0.502\u00b10.079 mm; intermediate, 0.525\u00b10.070 mm; high, 0.535\u00b10.066 mm;\n            <jats:italic>P<\/jats:italic>\n            &lt;0.001) and increased aortic intima-media thickness (exposure groups: low, 0.527\u00b10.113 mm; intermediate, 0.563\u00b10.139 mm; high, 0.567\u00b10.126 mm;\n            <jats:italic>P<\/jats:italic>\n            =0.008). The flow-mediated dilation decreased when cotinine level increased (exposure groups: low, 10.43\u00b14.34%; intermediate, 9.78\u00b14.38%; high, 8.82\u00b14.14%;\n            <jats:italic>P<\/jats:italic>\n            =0.004).
