Objective To analyze and predict the trend in mortality rate of sto mach cancer in twenty years in China. Methods Stomach cancer mortality data c ollected from the China national survey over the period 1970s-1990s for the cau se of death were analyzed. Results The adjusted mortality rate of stomach cance r in 1990s increased by 11.0% and 6.3% for males and females, respectively. The urban mortality in 1970s was slightly higher than the rural mortality, while in 1990s the rural mortality rate was about 60% higher than the urban mortality. In 1990s, the adjusted urban mortality rate decreased by 22.2% and 26.7% for males and females, respectively. In contrast, the rural mortality rate increased by 2 6.4% and 22.1% for males and females, respectively. The sex ratio of stomach can cer deaths in 1990s, both in cities and rural areas, was slightly greater than t hat in 1970s, being more marked in the latter areas. In 1990s, the mortality rat e decreased in 12 provinces, accounting for 44% in both sexes(12/27), but the de crease was more marked for females than for males except in Kiangs province. In provinc es where the increased rates ranked top six positions, the magnitude of increase in rates was higher in males than in females. Conclusion The overall mortalit y rates of stomach cancer in the past 20 years in China presented an increasing trend, despite there were upward and downward changes in 27 provinces and decrea se in cities while increase in rural areas. Compared with other countries, the w orld-adjusted mortality rate of stomach cancer for both sexes in China ranks fi r st. The increasing trend in stomach cancer mortality was seen in the older age g roups (60 years) while a decreasing trend was seen in the younger age groups (3 0-59 years). Aging of the population could be an important factor responsible f or the increase in mortality rates of stomach cancer in China.
