Abstract

OBJECTIVE:

To explore the feasibility and effectiveness of worksite-based cardiovascular disease (CVD) prevention and control program in urban population of China.

METHODS:

Worksite-based intervention program was implemented 110 000 employees at Capital Iron and Steel Company of Beijing (CISC) focusing on primary prevention for CVD and control of hypertension. Intervention components comprised of infrastructure setting-up, health education and health promotion, professional training, detection and management of hypertensive patients, and reasonably readjusting their diet structure focusing on salt intake reduction, reducing their overweight, quitting smoking, and restricting alcohol consumption in high-risk population. Changes in level of risk factors, incidence and mortality of stroke and coronary events and their trend were evaluated between the intervention group at CISC and eight simultaneously parallel reference groups in other provinces outside Beijing with population surveillance data.

RESULTS:

Major risk factors for CVD, including blood pressure, body mass index and serum cholesterol level, decreased relatively in intervention population at CISC during 1974 to 1998, while those in majority of eight parallel reference groups at different provinces of China significantly increased at the same time. Systolic blood pressure (SBP) decreased by 0.8 mm Hg and 4 mm Hg in average for men and women, respectively, and their diastolic blood pressure (DBP) remained the same as baseline for both men and women at CISC, while SBP increased by (2 - 11) mm Hg and (6 - 8) mm Hg in average for men and women, respectively in reference groups, and DBP increased by (2 - 6) mm Hg in average for men in five of eight reference groups, and by (3 - 6) mm Hg for women in four of eight reference groups. Serum level of cholesterol decreased by 0.26 mmol/L in women and slightly increased for men at CISC, and increased by (0.35 - 0.97) mmol/L for men and (0.29 - 1.05) mmol/L for women in all reference groups. Prevalence of overweight increased by 58.7% for men and 11.3% for women at CISC and increased by one to 22 folds in eight reference groups. Awareness of health knowledge improved significantly with an average net reduction of SBP/DBP of (2.5/2.2) mm Hg in the enforced intervention group at CISC than that in general intervention groups. Incidence and mortality rates of stroke decreased by 54.7% and 74.3%, respectively in intervention group at CSIC, but those of coronary events slowly increased with fluctuation.

CONCLUSION:

Worksite-based comprehensive intervention for CVD prevention and control was feasible and cost-effective in decreasing risk factors for CVD, incidence and mortality rate of stroke in population of urban areas of China.
