メモ：食事量の過少申告に関わる要素
女性、肥満者、糖尿病罹患者、低所得者、非就労者、非英語圏からの移民、識字率の低さなどとの関連が指摘されている
（識字率の低さ ＝ 抽象概念の操作が困難、食事量を数値化して日割り月割りで再計算できない）

Literacy and body fatness are associated with underreporting of energy intake in US low-income women using the multiple-pass 24-hour recall: a doubly labeled water study.

DESIGN:
Four multiple-pass 24-hour recalls (2 in person, 2 by telephone) were obtained over a 14-day period to estimate energy intake.
Total energy expenditure was measured over the same 14-day period using the doubly labeled water method.
Body composition was measured using dual energy x-ray absorptiometry, and literacy was measured by the Wide Range Achievement Test (WRAT) for reading and spelling.
CONCLUSIONS:
The multiple-pass 24-hour recall did not generate a group measure of energy intake that was accurate or unbiased in this sample.
Underreporting was strongly associated with increased body fatness. The ability to read and spell as measured by the WRAT improved the accuracy of the women's recall of their food intake.
