Association Between Family History and the Onset Age of Essential Hypertension in Han Population in Shanghai China

Abstract

Genetic factor is one of important influencing factors of essential hypertension, and family history (FH) is an important marker of genetic factors. To explore the association between family history and the onset age of essential hypertension in Han population in Shanghai China. According to l:l matched pairs design, 342 cases of hypertension and 342 controls were selected and investigate their nuclear family members in the case-control study. The diagnostic information of hypertension in all relatives of these two groups was investigated. The method of genetic epidemiology research was used to explore the effect of family history. The average prevalence of hypertension was 23.32%. The prevalence of hypertension of first-degree relatives was 33.99%; the prevalence of second-degree relatives was 17.60%; the prevalence of third-degree relatives was 13.51%. All prevalence of hypertension of case group relatives were significantly higher than that of control group relatives. The average onset age in population with positive FH is 48.74±11.16 years old, and the average onset age in population with negative FH is 54.38±9.87 years old. The difference about two FH groups showed statistically significant (t=4.589, P<0.001).

Epidemiologic Profile of Hypertension in Northern Iranian Population: The PERSIAN Guilan Cohort Study (PGCS)

“…This confirms the hereditary pattern of hypertension [ 58 ]. Moreover, higher levels of hypertension awareness and control in family history positive patients may be due to frequent contact with health care professionals and more attention to their health status [ 59 ].…”
