We used an ecological approach to determine the correlation between vegetable, fruit and salt intakes, refrigerator use, and gastric cancer mortality in Korean population. Information on fruit and vegetable intakes per capita from the National Health and Nutrition Survey, death certificate data from the National Statistical office, refrigerator per household data from Korean Statistical Information Service, and salt/sodium intake data from a cross-sectional survey were utilized. Correlation coefficients were calculated between vegetable and fruit intakes, refrigerator per household, and gastric cancer mortality and between salt and sodium intakes, and gastric cancer mortality and incidence in the four areas. With 5, 10, and 15 years lag time, refrigerator usage and fruit intake were negatively associated with gastric cancer mortality (p < 0.01), but vegetable intake was not associated with gastric cancer mortality. When estimates of salt/sodium intake evaluated by 24-h urine collection in four areas of Korea were compared to the gastric cancer mortality and incidence in these regions, positive correlation was shown between salt/sodium intake, and gastric cancer incidence and mortality. Negative associations between refrigerator use, fruit intake, and gastric cancer mortality and positive associations between salt/sodium intake and gastric cancer mortality and incidence were suggested.
我们采用生态方法来确定蔬菜、水果和盐摄入量、冰箱使用情况与韩国人群胃癌死亡率之间的相关性。利用了来自国家健康和营养调查的人均水果和蔬菜摄入量信息、来自国家统计局的死亡证明数据、来自韩国统计信息服务的每户冰箱数据以及来自横断面调查的盐/钠摄入量数据。在四个地区计算了蔬菜和水果摄入量、每户冰箱和胃癌死亡率之间的相关系数，以及盐/钠摄入量和胃癌死亡率和发病率之间的相关系数。随着 5、10 和 15 年的滞后时间，冰箱使用和水果摄入与胃癌死亡率呈负相关（p<0.01），但蔬菜摄入与胃癌死亡率无关。当比较韩国四个地区 24 小时尿液收集评估的盐/钠摄入量与这些地区的胃癌死亡率和发病率时，盐/钠摄入量与胃癌发病率和死亡率呈正相关。冰箱使用、水果摄入与胃癌死亡率呈负相关，盐/钠摄入量与胃癌死亡率和发病率呈正相关。
