Dietary pattern transition and its nutrient intakes and diet quality among Japanese population: results from the 2003-2019 National Survey.

ABSTRACT:

Objective

While many Asian countries undergo dietary transitions, little is known about Japan's dietary pattern changes and their impact on nutritional intake. We aimed to examine 17-year trends in dietary patterns and nutrient intakes in Japan.

Design

Principal component analysis was used to derive dietary patterns. The nutrient intake of subjects with principal component scores in the highest quartiles of each dietary pattern was assessed using the NRF9·3, which is a scale that evaluates the entire diet in terms of nutrient density.

Setting

Japan.

Participants
