Fourth-grade children’s dietary recall accuracy for energy intake at school meals differs by social desirability and body mass index percentile in a study concerning retention interval
Data from a study concerning retention interval and school-meal observation on children’s dietary recalls were used to investigate relationships of social desirability score (SDS) and body mass index percentile (BMI%) to recall accuracy for energy for observed (n=327) children, and to reported energy for observed and unobserved (n=152) children. Report rates (reported/observed) correlated negatively with SDS and BMI%. Correspondence rates (correctly reported/observed) correlated negatively with SDS. Inflation ratios (overreported/observed) correlated negatively with BMI%. The relationship between reported energy and each of SDS and BMI% did not depend on observation status. Studies utilizing children’s dietary recalls should assess SDS and BMI%.
Currently, most of the existing web cache replacement strategies are based on temporal locality, frequency distribution and size distribution while spatial locality gets less attention. This paper proposed a reference model to evaluate the spatial locality of web object accessing, and used the reference model as the basis of a new cache replacement strategy -- GDSR, Greedy-Dual-Size Reference. GDSR improved the performance of cache replacement strategy, providing a new direction and idea for the design of web cache replacement strategies.
