Abstract
Introduction: Systolic hypertension (SHT) is an independent cardiovascular risk factor. Objectives: To study the prevalence of SHT and causal factors in a young population. Materiel: 27746 subjects, age 15-65 yr., untreated for hypertension (HT) from a cohort of 30.000 employees that had been formed to study the incidence of HT in the French working population (AIHFP). BP was measured at 5, 6 and 7 minutes rest while seated using a validated automatic sphygmomanometer. Risk factors were sought by questionnaire.
Results: Prevalence of SHT was defined by SBP > 140 and DBP< 90 mmHg. (See Table)

In young men SHT occurs in 5% and increases with age from 40 – 50 yr. The prevalence is negligible in young women and increases after 45-50yr to reach a prevalence around 10%. In men and in women the presence of isolated systolic HT is consistently greater than DHT. Multivariate analysis reveals risk factors for SHT in men to be body mass index (BMI), alcohol and tobacco consumption. Heart rate is higher in subjects with SHT ;
Conclusion: The term SHT is often considered only in the aged. The prevalence increases with age but is not uncommon in young men. This is important for risk factor management.
