Abstract

<p>Objective: The Japanese National Health and Nutrition Survey (JNHNS) is conducted to estimate intakes of foods and nutrients among Japanese people. ​This study aimed to compare national nutrition surveys conducted in other countries to the JNHNS.</p><p>Methods: Information on national nutrition surveys in Australia, Brazil, Canada, China, Finland, Germany, Japan, Korea, Russia, the U.K., and the U.S. was gathered mainly through webpages of institutions in charge of conducting surveys.</p><p>Results: Most countries conducted surveys on their own, but some collaborated with another country. ​The surveys were household based in almost half of the countries, and were individual based in the other half. ​Most countries targeted both children and adults. ​In Japan, the Ministry of Health, Labour and Welfare delegates fieldwork to the public health centers in each targeted district, but this system was not seen elsewhere; instead, staff of the institutions conducting the survey worked as interviewers or recruited interviewers specifically for the surveys.</p><p>Dietary intake was assessed by 24-hour dietary recall in eight out of the 11 countries, and five countries combined multiple methods. ​The survey frequencies were continuous, regular (annually to once every few years), or erratic. ​Fieldwork was conducted either at one point of the year or throughout the year.</p><p>To obtain and use the survey data, some countries required researchers to apply and be approved, while others were open access.</p><p>Conclusion: Various systems and methods for conducting national nutrition surveys were seen in foreign countries, and these findings can provide useful information to consider during future implementation of JNHNS.</p>
