ABSTRACT
Abstract Objective:
To compare direct and self-reported anthropometry in Mexican women. Materials andmethods:
Women aged 30-72 years, participating in the Mexican Teachers' Cohort, completed a questionnaire with their anthropometric data in 2006-2008. After eleven months (median time), technicians performed anthropometry in 3756 participants. We calculated correlations and multivariable-adjusted mean differences between direct and self-reported anthropometric measures.Results:
Correlations between direct and self-reported anthropometric measures ranged from 0.78 (waist circumference) to 0.93 (weight). On average, women over-reported their height by 2.2 cm and underreported their weight, body mass index (BMI) and waist and hip circumferences by 1.3 kg, 1.3 kg/m2, 1.8 cm and 1.9 cm, respectively. Errors in self-reported anthropometry increased with rising measured BMI and were also independently associated with age, education and socioeconomic status.Conclusion:
Self-reported anthropometry is sufficiently valid for epidemiological purposes in adult Mexican women. Errors in self-reported anthropometry might result in underestimation of the prevalence of overweight and obesity.RESUMEN
Resumen Objetivo:
Comparar antropometría directa y autorreportada en mujeres mexicanas. Material ymétodos:
Participantes de la cohorte ESMaestras completaron un cuestionario con sus datos antropométricos en 2006-2008. Once meses después (tiempo mediano), técnicos realizaron antropometría (n=3 756). Se calcularon correlaciones y diferencias de medias ajustadas entre medidas antropométricas directas y autorreportadas.Resultados:
Las correlaciones entre medidas antropométricas directas y autorreportadas variaron entre 0.78 (circunferencia de cintura) y 0.93 (peso). En promedio, las mujeres sobrerreportaron su estatura en 2.2 cm y subreportaron su peso, índice de masa corporal (IMC) y circunferencias de cintura y cadera en 1.3 kg, 1.3 kg/m2, 1.8 cm y 1.9 cm, respectivamente. Los errores en la antropometría autorreportada se incrementaron a mayor IMC medido y se asociaron de manera independiente con edad, escolaridad y nivel socioeconómico.Conclusión:
La antropometría autorreportada es suficientemente válida para fines epidemiológicos en mujeres mexicanas. Los errores en la antropometría autorreportada podrían originar subestimación de la prevalencia de sobrepeso y obesidad.
