Incidence of hypertension, hyperglycemia and hyperlipidemia: The results from a national survey

Incidence of hypertension, hyperglycemia and hyperlipidemia are lacking in Taiwan. We aim to perform a nationwide population-based survey, named the Taiwanese Survey on Prevalence of Hypertension, Hyperglycemia and Hyperlipidemia (TwSHHH), to estimate the incidence rates of hypertension, hyperglycemia and hyperlipidemia. In 2002, a total of 6600 in 7578 subjects enrolled in a survey and collected complete data from interview and physical examination. There was 5942 survival and 658 dead collected in 5yr follow-up. Of them, 4682 subjects completed questionnaire interview, measurement of blood pressure, and collection of blood and urine samples, and followed disease outcome by insurance and death data. The subjects in 2002 who were free of the hypertension, hyperglycemia and hyperlipidemia were used to estimate the relevant incidence. The 5yrs cumulative incidence was 24.2‰ of hypertension, 7.3‰ of hyperglycemia, 20.4‰ of hyperlipidemia. In general, these incidences had gender difference, increased with aging and varying with resident region. Men had higher incidence than women, especially in those subjects age ranged 15-40 yrs. However, an inverse appeared in age group 40-59 yrs. Among those age over 60 yrs, over 6.5% men and 7.5% women had incident hypertension, over 1.3% men and 1.5% women had incident hyperglycemia, and over 3.5% had incident hyperlipidemia in 5yrs following. Our findings emphasize the urgent need to develop national strategies for the prevention and detection, especially those over 60 years, of the hypertension, hyperglycemia and hyperlipidemia in Taiwan.
