“…The capacity of estimated BMI based on reported measures to diagnose non-obese adolescents was satisfactory, since nine of ten adolescents that were not obese were correctly classified. This finding is consistent with other investigations 7,17,18 . Positive predictive value was lower than that observed in other reports with adolescents 7,21 .…”

ResumoObjetivo: Avaliar a validade do peso, estatura e Índice de Massa Corporal (IMC) referidos e sua confiabilidade para o diagnóstico do estado nutricional de adolescentes de Piracicaba. Métodos: Participaram do estudo 360 adolescentes de ambos os sexos, de escolas públicas de Piracicaba, com idade entre 10 e 15 anos. Os adolescentes autorelataram seu peso e estatura, sendo esses valores obtidos por medidas diretas, logo em seguida, pelos entrevistadores. A validade do IMC referido foi calculada segundo índices de sensibilidade, especificidade e valor preditivo positivo (VPP). Avaliou-se a concordância entre as categorias de IMC obtido por meio das medidas referidas e aferidas a partir do coeficiente kappa ponderado, coeficiente de correlação de Lin. e grá-ficos de Bland e Altman e Lin. Resultados: Verificou-se que tanto os meninos quanto as meninas subestimaram o peso (−1,0 meninas e meninos) e a estatura (meninas −1,2 e meninos −0,8) (p < 0,001). Os valores de IMC aferidos e referidos apresentaram uma concordância moderada. A sensibilidade do IMC referido para classificar os indivíduos obesos foi maior para os meninos (87,5%), enquanto a especificidade foi maior para as meninas (92,7%). O VPP foi elevado somente para a classificação da eutrofia. Conclusões: As medidas referidas de peso e estatura de adolescentes não representam medidas vá-lidas e, portanto, não devem ser usadas em substituição aos valores mensurados. Além disso, verificou-se que 10% dos meninos obesos e 40% das meninas obesas poderiam permanecer não identificados utilizando-se as medidas auto-referidas, confirmando a baixa validade das medidas auto-referidas. Palavras AbstractPurpose: To assess the validity and reliability of self-reported height, weight, and Body Mass Index (BMI) to diagnose the nutritional status of adolescents. Methods: The study included 360 public school students of both genders, with ages ranging from 10 to 15 years. Adolescents self-reported their weight and height, and these values were later obtained directly by interviewers. The validity of BMI based on self-reported measures was calculated using sensitivity and specificity indexes, and positive predictive value (PPV). Agreement between self-reported and measured BMI was evaluated using Kappa's weight coefficient, the Lin correlation coefficient, and Bland-Altman and Lin's plots. Results: Both girls and boys underestimated their weight (−1.0 girls and boys) and height (girls − 1.2 and boys − 0.8) (p < 0.001). BMI presented moderate agreement between measured and self-reported values. Sensitivity of estimated BMI based on reported measures to classify obese subjects was higher for boys (87.5%) than it was for girls (60.9%), whereas specificity was higher for girls (92.7%) than it was for boys (80.6%). PPV was high only for classification of normal-weight adolescents. Conclusions: Self-reported measures of weight and height in adolescents do not present valid measures; therefore, they should not be used to replace measured values. Additionally, we observed that 10% ...

“…BMI calculated from self-reported body weight and height in adolescents is reported to be less valid because of possible under-reporting of weight and overestimation of height (Crawley and Portides, 1995;Strauss, 1999;Wang et al, 2002;Brener et al, 2003;Shapiro and Anderson, 2003). Therefore, the number of overweight adolescents is likely to be underestimated in current study.…”

Skipping breakfast, alcohol consumption and physical inactivity as risk factors for overweight and obesity in adolescents: results of the E-MOVO project

Objective/Background: To investigate the association between skipping breakfast, alcohol consumption and physical inactivity with overweight and obesity in adolescents. The design comprises cross-sectional electronic health survey (E-MOVO). Subjects/Methods: Over 35 000 Dutch adolescents in grade 2 (13-14 years of age) and grade 4 (15-16 years of age) of secondary educational schools were recruited by seven community health services. Analyses were performed on 25 176 adolescents. Body mass index was calculated from self-reported body weight and height. Frequency of skipping breakfast per week, amount of alcoholic drinks consumed per occasion, and numbers of physical active days per week were considered as determinants for overweight and obesity. Results: In grade 2, adjusted odds ratios for the association with overweight were 2.17 (95% CI: 1.66-2.85) for skipping breakfast, 1.86 (1.36-2.55) for alcohol consumption and 1.73 (1.19-2.51) for physical inactivity. Statistically significant associations with overweight were also found in grade 4. In grade 2, dose-response relations (P for trend o0.05) were present between all risk factors and overweight. In a multivariate model containing all risk factors, breakfast skipping showed the strongest relation with overweight (OR 1.68, 95% CI 1.43-1.97 for grade 2, OR 1.32 95% CI 1.14-1.54 for grade 4) and obesity. Conclusions: Skipping breakfast, alcohol consumption and physical inactivity were associated with overweight in second and fourth grade adolescents. The associations were strongest for younger adolescents. The most important risk factor for overweight and obesity was skipping breakfast.

“…Self-report of weight and height may affect accuracy of BMI values and lead to underestimation of the prevalence of OW. Indeed, it has been demonstrated that adolescents aged 415 years tend to underestimate their weight and overestimate their height (Wang et al, 2002b;Brener et al, 2003). However, according to Strauss (1999), calculations of BMI are less inaccurate in children since they tend to underestimate both weight and height.…”

Child overweight in France and its relationship with physical activity, sedentary behaviour and socioeconomic status

et al. 2006

Objective: (1) To assess the prevalence of childhood overweight (OW) and obesity in France; (2) to examine how physical activity and sedentary behaviour are involved in the association between socioeconomic status (SES) and OW, while taking into account total energy intake. Design and subjects: Representative sample of French children aged 3-14 years (n ¼ 1016) taken from the 1998-1999 crosssectional French INCA (Enquête Individuelle et Nationale sur les Consommations Alimentaires) food consumption survey. Measurements: Weight and height, leisure-time physical activity (LTPA), sedentary behaviour (TV viewing and video-game use), and SES were reported by parents or children by answering questionnaires; total energy intake was assessed using a 7-day food record. Results: In total, 15.2% (95% CI: 13.0-17.6) of the children are OW (including obese), according to the IOTF (International Obesity Task Force) definition. OW is inversely associated with SES in children over 6 years of age. LTPA is negatively correlated to OW among the 3 to 5-year-old children only, whereas sedentary behaviour is positively related to OW in childhood and adolescence. From 6 years old on, SES is inversely associated with sedentary behaviour, which consequently may partly mediate the relationship between SES and OW. Conclusion: This study confirms the association between SES, sedentary behaviour and childhood OW in France. It was performed before the launching of the French Program of Nutrition and Health (PNNS) in 2001 and will be repeated in 2006. This will contribute to monitoring both childhood OW and its main determinants at the population scale.
