The prevalence of isolated systolic hypertension and risk of stroke in the elderly in Macau

Objective To investigate the prevalence of isolated systolic hypertension(ISH) and risk of stroke in the elderly in Macau. Methods The authors examined 5 177 subjects who were randomly sampled from several communities and the surveyed items included measurement of blood pressure, height,weight and some risk factors of hypertension and stroke.All the interviewers were trained before participating in the survey. Results The prevalence of defined ISH was 4 17%, and that of critical ISH was 4.90%, being higher in women than those in men; the prevalence of defined and critical ISH rose with increase of age.The increase was remarkable in women. The risk of stroke also rose with increase of age. Multivariate analysis showed stroke was positively related with age( P <0.05)and increase of systolic pressure( P <0.01). Conclusions ISH is much common in the elderly.It seriously endangers the health of aged people and is associated with higher relative risk of stroke. Prevention of hypertension in community population should be further strengthened.
