Prevalence, awareness, treatment and control of hypertension in the Malaysian adult population: results from the national health and morbidity survey 1996.

We determined the prevalence of hypertension and the level of awareness, treatment and control of hypertension among Malaysian adults in a population based cross-sectional survey. Twenty-one thousand and three hundred ninety-one adults aged 30 or older in all 13 states of Malaysia in 1996 were sampled using a stratified two-stage cluster sampling design. Thirty-three percent of adults had hypertension with a higher percentage among women. Among hypertensives, 33% were aware of their hypertension, 23% were currently on treatment and a mere 6% had controlled hypertension. There was practically no difference in mean BP between treated and untreated hypertensives. Concerted public health effort is urgently required to improve the detection, treatment and control of hypertension in Malaysia.
