The following factors may be involved in the pathogenesis of hypertension

( 1) the age and sex of the incidence of hypertension increased with age. According to the domestic data, 40 years following the average incidence of 3.4%, 40～ 49 years old was 10.2%, 50～ 59 years old was 17.2%, 60 years of age or older is 24.1%. Hypertension prevalence rate of 6.96%, 8.4% for females, females than males. Generally speaking, in the past 35 years the incidence rate in male is slightly higher than that of women, after the age of 35 in females than in males, which may be associated with the women's pregnancy and menopause hormonal changes related to.

( 2) the work nature different occupation personnel, the incidence of hypertension is very different. Concerned data shows, mainly on mental labor onset rate reached 7.78%, manual workers reached 4.68%, while engaged in nervous degree of high occupation such as drivers, conductors, the prevalence of hypertension is high up to 11.3%.

( 3) obesity or overweight many epidemiological data showed that obesity hypertension opportunities than normal high 2 ~ 4 times, reduce body weight blood pressure tends to decrease along. If the weight exceeds the standard weight 15%, consideration should be given to lose weight.

( 4) the history of hypertension in patients with essential hypertension of pregnancy women often had pregnancy-induced hypertension history. According to reports, there was a statistically 440 in pregnancy induced hypertension history for 172 people, the incidence is 39.06%.

( 5) a lot of information on genetic hypertension have a certain relationship with the genetic.

( 6) diet, hobby concerned data makes clear, food properties and the pathogenesis of hypertension have a certain relationship. Eating meat food more, its incidence is higher, such as don't eat meat for 48 people, I often eat meat meat 458 people, 556 people, its incidence respectively of the total incidence number 4.6%, 43.5%, 52.9%. While drinking, smoking habits and the incidence of hypertensive disease relationships reported less consistent throughout.

( 7) too much food, eating too much salt can cause hypertension, there are many reports. The researchers found that, Arctic Eskimos and some Pacific island natives, eat less salt, almost can not find the hypertension patient. China's Liangshan Yi salt quantity is less, the prevalence of hypertension is the lowest in the country, and Tibet Tibetan Lhasa due to drinking salty tea living habits, the prevalence of hypertension in the highest; North China residents salt than the south, therefore the prevalence of hypertension was significantly higher than that in the south.

( 8) women's contraceptive drug, hormone ( prednisone, dexamethasone ), anti-inflammatory painkillers such as indomethacin and herbal ephedra, licorice has the pressor effect, thus hypertensive patients in the application of the drug to the attention of.
