Cardiovascular disease risk factors are highly prevalent in the office-working population of Nanjing in China

Abstract Objective To establish a profile of the modifiable cardiovascular disease (CVD) risk factors in the office-working population of Nanjing, China. Background With increasing modernization in China, CVD is now common among Chinese. Relevant information on the prevalence of CVD risk factors in China is, however, limited. Methods We recruited 2648 office working people aged 23–79years without history of CVD or diabetes from 7 work units of Nanjing during the years 2003 to 2005. Information from a self-reported questionnaire on lifestyle, physical examination, fasting blood for lipid profiles, and a 75-gram oral glucose tolerance test (OGTT) were obtained from each participant. We analyzed the following 7 CVD risk factors: smoking, inadequate physical activity, unhealthy dietary habit, obesity, hypertension, dyslipidemia, and hyperglycemia. Results The whole study population had an average of 2.8 risk factors, while 95.6%, 79.4% and 55.6% of them had respectively ≥1, ≥2 and ≥3 of the 7 CVD risk factors. Men had a higher proportion of smoking, hypertension, dyslipidemia, hyperglycemia, but lower in light physical activity compared with women. Number of CVD risk factors increased with age. Although risk factors in men were more common than women, they increased alarmingly in postmenopausal women. Conclusions CVD risk factors are common in office-working people in Nanjing, China. Effective interventions and treatment against risk factors should be adopted in the high risk population, which may greatly reduce the future burden of CVD in the Chinese population.
