Misreporting of dietary energy intake in adolescents

Abstract

Objectives: To examine the prevalence of under and overreporting of energy intake in adolescents and their associated factors. Methods:Cross-sectional study with 96 postpubertal adolescents (47 normal-weight and 49 obese), mean age of 16.6±1.3 years. Weight and height were measured, and body mass index was calculated. Body composition was assessed by dual energy X-ray absorptiometry. Dietary intake was evaluated by a 3-day dietary record. Biochemical assessment was performed (serum total cholesterol, LDL-cholesterol, HDL-cholesterol, plasma glucose, and insulin). Underreporters reported energy intake < 1.35 x basal metabolic rate (BMR), whereas overreporters reported energy intake > 2.4 x BMR. Results:Energy intake misreporting (under or overreporting) was identified in 65.6% of adolescents (64.6 and 1% of under and overreporting, respectively). Obese adolescents were 5.0 times more likely to underreport energy intake (95%CI 2.0-12.7) than normalweight participants. Underreporters showed higher rates of insufficient intake of carbohydrate (19.3 vs. 12.1%, p = 0.046) and lipids (11.3 vs. 0%, p < 0.001) than plausible reporters. Cholesterol intake was also lower in underreporters (p = 0.017). There were no significant differences in body composition and biochemical parameters in relation to misreporting. Conclusions:The results obtained demonstrated a high percentage of misreporting of energy intake among adolescents, especially among obese subjects, which suggests that energy-adjusted nutrient intake values should be employed in diet-disease risk analysis in order to contribute to a reduction in errors associated with misreporting.J Pediatr (Rio J). 2010;86(5):400-404: Adolescents, dietary assessment, energy intake, misreporting, underreporting. ResumoObjetivos: Examinar a prevalência da sub e supernotificação da ingestão energética em adolescentes e seus fatores associados.Métodos: Estudo transversal com 96 adolescentes na pós-puberdade (47 com peso normal e 49 obesos), com idade média de 16,6±1,3 anos. Peso e altura foram medidos e o índice de massa corporal foi calculado. A composição corporal foi avaliada através de absorciometria por raios X de dupla energia. A ingestão de alimentos foi avaliada por meio de um registro alimentar de 3 dias. Realizou-se uma avaliação bioquímica (níveis séricos de colesterol total, LDL, HDL, glicose plasmática e insulina). Os subnotificadores relataram uma ingestão energética < 1,35 x taxa metabólica basal (TMB), enquanto os supernotificadores relataram uma ingestão energética > 2,4 x TMB.Resultados: Notificação imprecisa (sub ou supernotificação) da ingestão energética foi identificada em 65,6% dos adolescentes (64,6 e 1% de sub e supernotificação, respectivamente). Os adolescentes obesos apresentaram 5.0 vezes mais chances de subnotificar a ingestão energética (IC95% 2,0-12,7) do que os participantes com peso normal. Os subnotificadores apresentaram taxas mais altas de ingestão insuficiente de carboidratos (19,3 versus 12,1%, p = 0,046) e de lipídios (11,3 versus 0%, ...

A systematic review and meta‐analysis of energy and macronutrient intake responses to physical activity interventions in children and adolescents with obesity

“…Although the included studies show an important methodological heterogeneity regarding the content of their interventions, their durations and the assessment of body composition or other physical characteristics, they all used dietary recall to assess food intake. Yet this remains a self‐reported method to assess energy consumption that is highly subjective (especially among children and adolescents with obesity) , and its use in all the selected studies facilitates comparisons.…”

Dietary fat intake modifies the influence of the FTO rs9939609 polymorphism on adiposity in adolescents: The HELENA cross-sectional study

“…One of the main pitfalls in dietary assessment by self-reported dietary recall is underreporting energy intake in youth overweight participants [37,38]. To account for this, we conducted sensitivity analyses and excluded under-reporters from the analyses and the results did not change.…”

Intake at a single, palatable buffet test meal is associated with total body fat and regional fat distribution in children

“…For example, a majority of self-reported energy intake data from the National Health and Nutrition Examination Survey (NHANES) are not physiologically plausible (Archer, Hand, & Blair, 2013). Moreover, there are examples of both under-and over-reporting across other studies that use self-reported energy intake, particularly in children and adolescents (Fisher, Johnson, Lindquist, Birch, & Goran, 2000;Forrestal, 2011;Santos, Pascoal, Fisberg, Cintra, & Martini, 2010). Heavier youth are more likely to underreport the amount they eat on self-report measures compared to their actual intake (Wolkoff et al, 2011).…”
