Cigarette smoking, blood pressure and pulse rate in the Jerusalem Lipid Research Clinic Prevalence Study.

The relationship between cigarette smoking and blood pressure (BP) and pulse rate (PR) was studied in a sample of 1,242 Jerusalem youngsters and 1,703 adults. Confounding effects of age, body mass, ethnic origin and season were controlled in the analysis. Both mean systolic (SBP) and diastolic blood pressure (DBP) were lower in smokers than in nonsmokers, with greater differences in both generations in females (women 4.5 mm Hg, P = 0.004 and girls 3.9 mm Hg, P less than 0.001 for SBP; women 2.3 mm Hg, P = 0.024 and girls 2.6 mm Hg, P = 0.002 for DBP) than among the males (men 1.5 mm Hg, P = 0.15 and boys 2.0 mm Hg, P = 0.022 for SBP; men 1.3 mm Hg, P = 0.05 and boys 1.8 mm Hg, P = 0.01 for DBP). The relative odds of being in the upper age, ethnic and body mass index-adjusted quintiles of SBP for nonsmokers were 1.3, 1.9, 2.1, and 3.5 for men, boys, women, and girls, respectively. For DBP they were 1.3, 1.7, 1.1, and 2.1, respectively. No significant trends for BP varying with number of cigarettes smoked were noted in either adults or youngsters. Only adult male smokers had slightly higher PRs. The relatively small differences in BP may be of pharmacologic or psychobehavioral interest, but do not counter the well-described deleterious effects of cigarette smoking.
