Short questions for surveys about bread and cereal intake: Comparing measures of quantity versus frequency

Abstract

The use of short questions in population surveys can provide valuable information on food habits and how these habits change. In order to monitor trends in diet and make comparisons, standardised survey questions must be maintained over time. However, occasionally it may be desirable to replace older questions with improved ones. This study was commissioned by the NSW Adult Health Survey Program to compare the responses provided to older and more recent versions of questions to improve the data collected in health surveys on food habits.
