Identifying sodium intake using dietary behaviours
Published in PLoS One on 15 September 2020, Okada and Takimoto conducted a cross-sectional analysis to develop a brief screening method for determining sodium intake in order to raise public awareness of Dietary Reference Intakes in Japan. Self-administered questionnaires from one-day dietary records by a semi-weighed method within the 2015 National Health and Nutrition Survey were used to compare sodium intake and dietary behaviours. Logistic regression analysis was used to identify predictive factors by sex and by level of sodium intake. Of the 6,172 Japanese adults surveyed, participants with lower sodium intake were found to use nutrition labels and had a lower frequency of eating out than those with higher intakes (P<0.001). The authors conclude that this method could be used to identify sodium intake using dietary behaviours. To access the full text article, click here.
