Prevalence of hypertension among Chinese elderly and its relationship to behavioural and nutritional factors.
A cross-sectional study was carried out to determine the prevalence of hypertension in the Chinese elderly and to examine its relationship with various behavioural and nutritional risk factors. This study involved 243 Chinese aged 55 years and older in 2 randomly selected Chinese Villages in Seberang Prai Tengah, Penang. The study included an interview, anthropometric assessment and blood pressure measurement. The prevalence of hypertension was 48.1% and out of this, 65 (55.6%) were on anti-hypertensive treatment. There was a significant rise in the prevalence with age. Hypertension was found to be inversely related to per capita income and physical activity (p < 0.05). Hypertension was significantly more common in smokers than non-smokers. Alcohol intake in the elderly was low and not related to hypertension. Obesity was significantly associated with hypertension only among the elderly aged 55-64 years. The dietary intake of sodium, potassium and calcium did not differ significantly between the hypertensive and normotensive elderly.
