The attitude of people toward salty food [including their attention to reduce salt (NaCI) intake] was investigated by a questionnaire method in 524 adult subjects (131 men, and 393 women including 313 women in the 30 to 60 years age range) in a small farming village in northeastern Japan. Excretion of NaCI in urine was measured in 24-hr samples which were collected at the same time. The amount of NaCI excreted in urine varied significantly by age in men with a peak in their 40s and 50s, whereas essentially no age-dependent changes in the amount were observed in the 30–60 year old women. Further analysis among the 30–69 year-old women showed that those who paid attention to reduce NaCI intake excreted significantly less NaCI (10.6 g/day as a mean) than those who did not pay attention (11.9 g/day). The meaning of this observation is discussed.
