A
case-control study was conducted to investigate the
risk factors (Part of job,
Obesity, Alcohol,
Smoking,
Milk,
Salt, and
Family history) for
hypertension. We selected 330
hypertension cases (
male; 247,
female; 83) and 1,336 controls (
male; 887,
female; 449) from
employees in Taegu city from 1 May to 30 November, 1988. Data was analysed using a
logistic regression model. Statistically Significant elevated
odds ratio were noted for alcohol (
odds ratio=3.23),
obesity (odds ration=2.31),
salt (
odds ratio=1.75) in
male (P<0.05) and those in
female were noted for alcohol (
odds ratio=16.49),
family history (
odds ratio=3.70),
obesity (
odds ratio=1.74) and
salt (
odds ratio=1.73) (P<0.05). Statistically significant reduced
odds ratio was noted for
milk in both sexes (
odds ratio=0.69 for
male and 0.65 for
female) (P<0.05) and the
dose-response relationship between
milk intake and
hypertension was confirmed (P<0.05). Therefore,
milk seems to be preventive factor for
hypertension.
Smoking was not significantly associated with
hypertension in both sexes. The part of job was significantly associated with
hypertension in
female by simple
analysis (P<0.05) but the relationship was disappeared when
multivariate analysis (
logistic regression analysis) was done.
