RESUMEN
The study was conducted among northeast Thai male population aged 35-64 years in Phondistrict of Khon Kaen. Sampled population was selected by cluster ampling by levels of development of villages. Data collected were including, demographic data, cigarrette smoking, socioeconomic status, blood pressure, body weight, height and total serum cholesterol. There were 209 men from 8 villages with the average age of 47.6 years. About three quarters of them were farmers. The prevalence of systolic hypertension (\> = 160 mmHg), diastolic hypertension (\> = 95 mmHg) were 1.4% and 2.4% respectively. Means (SD) of systolic, diastolic blood pressures and total serum cholesterol were 115.6 (15.3) mmHg, 75.7 (9.6) mmHg and 147.7 (35.3) mg% respectively. Smoking rate was 75%, Overweight (BMI \> 25 kg/m2) was only 17% of the population. Both mean systolic and mean diastolic blood pressures had significant correlation with both total cholesterol level and body mass index, as well as the level of development of the villages.
