Study of risk factors for cardiovascular diseases of employees of one of the Tehran University of Medical Sciences in 1397

Cardiovascular diseases cause 17.9 million deaths annually and the aim of this study was to determine the risk factors for this disease in one of the universities of medical sciences in Tehran in 1397. 

 In a cross-sectional study, 617 employees of one of  the Tehran University of Medical Sciences in 1397 were surveyed. Data were collected through a questionnaire of demographic characteristics and lipoprofile values ​​of participants from the measurements made in the staff health monitoring plan. The collected data were entered into SPSS Version19.0 software. Atherogenic Index (ATI) with the formula log10 (TG / HDL-C) was calculated. Central and dispersion indices were used to describe the data and independent t-test, analysis of variance and Tukey post hoc test were used for analysis.

485 (78.6%) of the participants were male and the rest were female. Mean (standard deviation) age of participants was 45.2 years (7.8 years), service history 19.7 years (9.6 years), fasting glucose (mg / dl) 100.8 (23.3), triglyceride (mg / dl) 4/163 (116.5), low density lipoprotein (bad cholesterol) (mg / dl) 2/117 (31.7), high density lipoprotein (good cholesterol) mg / dl) 2 / 43 (3/10), total cholesterol (mg / dl) 4/192 (1/34), body mass index (Kg / m2) 1/27 (3.7), systolic and diastolic blood pressure (mmHg) participants 116.1 (12.4) and 74.4 (0.9) were determined, respectively. Difference between mean age (year), length of service (year), fasting glucose, triglyceride, low-density lipoprotein (bad cholesterol), high-density lipoprotein (good cholesterol), total cholesterol, systolic and diastolic blood pressure, and body mass index Were not statistically significant in both sexes (P = 0.052). One-way analysis of variance showed that the difference between the mean values ​​of total cholesterol (P = 0.000), low-density lipoprotein (P = 0.003) and high-density lipoprotein was statistically significant (P = 0.000) and It was not significant in other variables (P = 0.944). Tukey post hoc test showed that only the age group under 39 years were lower than total two cholesterol groups, low density lipoprotein and high density lipoprotein (P = 0.000).

All variables measured in this study are strongly associated with the incidence of cardiovascular disease and all of them can be used individually or in combination to predict the incidence of cardiovascular disease. The results show that the studied risk factors and especially atherogenic index are very suitable for screening populations.
