1Department of Public Health and Hygiene, Faculty of Medicine, Oita Medical University, Japan.
Summary
Stomach cancer mortality in Japan significantly decreased between 1970 and 1995 for both males and females. However, the impact on life expectancy highlights the need for targeted prevention strategies, considering age and gender differences.
Area of Science:
- Oncology
- Epidemiology
- Public Health
Background:
- Stomach cancer is the leading cause of cancer mortality in Japan.
- Understanding trends in stomach cancer mortality is crucial for public health initiatives.
Purpose of the Study:
- To analyze trends in stomach cancer mortality rates in Japan from 1970 to 1995.
- To examine the relationship between stomach cancer mortality, age, gender, and life expectancy.
Main Methods:
- Analysis of annual mortality data for stomach cancer in Japan.
- Inclusion of age, gender, and life expectancy as variables.
- Calculation of adjusted mortality rates and male-female mortality ratios.
Main Results:
- Adjusted stomach cancer mortality rates declined significantly: from 88.9 to 45.4 per 100,000 in males and 46.5 to 18.5 per 100,000 in females.
- The male-female mortality ratio ranged from 1.9-2.5, with higher rates in younger females.
- Stomach cancer reduced life expectancy by 0.65 years in males and 0.42 years in females.
Conclusions:
- Despite overall decreases, stomach cancer remains a significant public health concern in Japan.
- Prevention and control programs must consider the unique characteristics of stomach cancer in young women and the influence of population aging.
