The admissions data analyzed in this study was retrieved from the National Health Insurance Research Database claims files, from 1996 to 2012. The data of economic variables was obtained from government open information, including gross domestic product(GDP), healthcare expenditure(HE), expenditure of tobacco and alcohol(ECA), unemployment rate(UE) and air pollution exposure(APE). Using corner method to select potential factors, a transfer function model then was conducted in the multi-variated time series analysis. We collected those who suffered from CVDs and was over than 20 years old in the 17-years study period. Total admissions of 693,036 males and 358,440 females were ischemic heart disease(IHD), 145,151 males and 162,925 females were hypertension, 216,568 males and 140,230 females were stroke and 794,196 males and 568,964 females were other cardiovascular diseases (other CVDs). The results showed while increasing one station-day of APE, incident rate of IHD increases 0.47% after six months. Contrarily, the incident rate of stroke, and other CVDs presented 0.73% and 0.58% decline, respectively. While increasing 1% of UE prior to three quarter, the rate of IHD and stroke was increased 5.05% and decreased 2.70% in young men, respectively. In middle-age men, the rate of IHD and stroke was decreased 0.27% and increased 1.17% while increasing one US dollar of ECA prior to half year. While increasing one station-day of APE, the rate of hypertension and other CVDs was increased 0.30% and 0.016%. In elder men, while increasing one US dollar of HE prior to three months, IHD rate was decreased 0.29%. While increasing one US dollar of ECA, stroke rate was increased 1.11%. While increasing one station-day of APE, stroke and other CVDs were increased 0.70% and 0.25%, respectively. In young women, while increasing one US dollar of HE, IHD rate was decreased 0.70% after three months and hypertension rate was decreased 0.73% after a half year. While increasing one station-day of APE prior to three months, the rate of IHD and hypertension was decreased 0.83% and was increased 2.60%, respectively. While increasing 1% of UE, IHD rate was increased 2.53% after three quarters and other CVDs rate was decreased 1.90% after a half year, respectively. In middle-age women, while increasing one US dollar of HE, hypertension rate was decreased 0.56% after three months. While increasing one US of ECA, stroke rate was increased 1.59%. While increasing one station-day of APE, stroke rate was increased 0.53%. While increasing 1% of UE prior to a half year, IHD rate was increased 1.95%. In elder women, while increasing one US dollar of HE, IHD rate was decreased 0.39% after three months, stroke and other CVDs rate were decreased 0.46% and 0.18% after a half year, respectively. No relationship between GDP and each of CVDs was observed in all sub-groups.
Socioeconomic effects on CVDs are various among different population.
