Energy reporting characteristics among Canadians aged 2 years and older in 2004 and in 2015 (n = 20,738 in 2004 and n = 13,611 in 2015).
| Survey Cycle | ||||
|---|---|---|---|---|
| 2004 | 2015 | |||
| Mean | SE | Mean | SE | |
| Energy reporting category | ||||
| Underreporter (%) | 22.3 | 0.6 | 30.1 * | 0.8 |
| Plausible reporter (%) | 60.6 | 0.7 | 60.6 | 0.8 |
| Overreporter (%) | 17.1 | 0.6 | 9.3 * | 0.4 |
SE, Standard error. * Significant differences between 2004 and 2015 (p-value ≤ 0.05). Children and adults with measured weight and height were classified as either under-, plausible or over-energy reporters based on the ratio of reported vs. total energy expenditure (TEE). TEE was based on equations that account for height, weight, age, sex, physical activity levels, and a person’s weight status (normal weight vs. overweight/obese) [22]. Physical activity levels were assumed to be low active for children aged 13 and younger and sedentary for respondents aged 14 and older.
