[BDSP. Notice produite par INIST BTR0xi79. Diffusion soumise à autorisation]. Background. High salt and nitrate intake are considered as risk factors for stomach cancer, but little is known about possible interactions. This ecological study examines the respective importance of both factors for stomach cancer mortality at the population level using data obtained under standardized conditions and with biochemical analyses performed in the same laboratories. Method. Randomly selected 24-hour urine samples from 39 populations, sampled from 24 countries (N=5756 people for sodium, 3303 for nitrate) were obtained from the INTERSALT study. Median sodium and nitrate levels were age-and sex-standardized between ages 20-49 years and averaged per country. Ecological correlation-regression analyses were done in relation to national stomach cancer mortality rates. Results. The Pearson correlation of stomach cancer mortality with sodium for the 24 countries was : 0.70 in men and 0.74 in women (both P
