Research paper thumbnail of Validation and calibration of self-reported weight and height from individuals in the city of São Paulo

Methods: A cross-sectional, population-based study was performed with a sample of 299 adolescents, adults and elderly of both genders, in São Paulo in 2008. Bland-Altman difference plot and intraclass correlation were used to determine agreement between measured and self-reported parameters. Sensitivity and specificity were assessed for overweight, and calibration coefficients were estimated for correction of weight, height and body mass index data. Results: The intraclass correlation was high between self-reported and measured parameters for weight (r > 0,94) and body mass index (BMI) (r > 0,85). The agreement between measured and self-reported weight, height and BMI was good. Sensibility was > 91% and specificity was > 83%. Conclusion: Self-reported weight measurements can substitute measured parameters in this population, in both genders and in the age groups studied. Self-reported height measurements should be used with caution. Calibration coefficients can be used to adjust self-reported measurements.

Além do custo gerado à saúde, a produção da carne também gera grande impacto no meio ambiente. A partir dessas informações, elaborou-se o projeto Segunda Sem Carne na Faculdade de Saúde Pública. O trabalho tem por objetivo discutir os riscos causados à saúde e ao meio ambiente pelo consumo excessivo de carne bem como avaliar o impacto do mesmo na mudança do hábito alimentar da população estudada. A iniciativa contou com a divulgação de dados sobre consumo excessivo de carne, seus impactos na saúde e no meio ambiente, propondo a inclusão de um cardápio sem carne em uma segunda feira de cada mês do período letivo do ano de 2012 no restaurante da Faculdade de Saúde Pública da Universidade de São Paulo/COSEAS. Para avaliar a eficácia da iniciativa, foram realizadas três pesquisas de opinião com os comensais do restaurante ao longo do projeto, sendo uma online e duas presenciais. Sete meses após o início da intervenção, 73% dos pesquisados disseram estar mais conscientes sobre os malefícios associados ao consumo excessivo de carne; 42% disseram que diminuíram o consumo de carne devido aos esclarecimentos fornecidos pelo projeto.

A sample of individuals aged above 20 years, of both genders, living in São Paulo, was used for the validation study (n = 77) and reproducibility study (n = 74) of the food frequency questionnaire. To verify the validity and reproducibility of energy and 19 nutrients were applied two food frequency questionnaires (60 items) and three 24-hour dietary recalls (24HR - reference method). The validity was verified by Spearman correlation coefficient (crude and de-attenuated) and weighted Kappa, and reproducibility by intraclass correlation coefficients and weighted kappa. In analyzes of validity de-attenuated correlation coefficients ranged from 0.21 (carbohydrate) to 0.74 (energy), and weighted kappa exceeded 0.40 for 30% of the nutrients. Polyunsaturated fat and folate did not show significant correlation and ...
