In order to find the factors associated with the death of hypertensives, 12 year follow-up study for 267 hypertensives whose average blood pressure were 140/90 mmHg or above during their first health screening in 1979-1980 at YongJin Township,
Wanju
Country, North Cholla Province by the Community Health Team of Chonju Presbyterian Medical Center.
@ES The study results are as follows :
@EN 1. Initial general characteristics of hypertensives were studied. The age distribution of studied hypertensives showed 27.3% in 40-59 years, 25.8% in 50-59 years, 29.6% in 60-69 years and 17.2% in 70 + years old group. Marital status showed
that
82.2% of hypertensives had their were or husband, 74.5% were employed on agriculture, 56.5% of hypertensives were illiterate.
2. Among the hypertensives, 91.6% of male and 22.8% of female reported that they were smokers, 82.6% of hypertensives had body mass index lower than 25 Kg /㎡. 46.8% of average systolic blood pressure were 160mmHg or above and 54.3% of average
diastolic blood pressure were 95mmHg or above.
3. Twenty percent of hypertensives reported that they were treating hypertension at the beginning of follow-up, while 68.5% reported that they were not treated, 28.1% reported that they were treating hypertension within 6 months before last
follow-up,
but 69.3% reported that they were not treated for hypertension within 6 months before last follow-up. So 50.6% were classified as never treated group and 41.2% as treated group.
4. Average blood pressure for initial 3 years were calculated. The change of average systolic blood pressure was observed as 161.3±19.4mmHg at the first year, 145.6±28.0mmHg at the second year and 141.4±37.2mmHg at the third year. Average
diastolic
blood pressure were changed from 96.2±14.4mmHg at the first year to 90.6±18.6mmHg at the second year and 86.4±22.9mmHg at the third year.
5. By the follow-up of hypertensives, 54 hypertensives(46.2%) among 117 male hypertensives and 50 hypertensives (33.3%) among 150 female hypertensives died for 12 years. 42.6% of male death and 52.0% of female death were caused by
cerebrovascular
diseases.
6. Through univariate statistical test about the association between general characteristics or cardiovascular risk factors of hypertensives and mortality for 12 years, age variable among male and among female age, marital status, occupation,
educational level, systolic blood pressure and treatment status were shown as significant variable to influence upon the mortality.
7. By multiple logistic regression analysis, among male age and systolic blood pressure were selected as significant variable to be associated with the total mortality for 12 years. Among female age, systolic blood pressure and treatment status
were
selected as statistically significant variable to be associated with the total mortality for 12 years.
