[Design and validation of a new dietary habits questionnaire for the overweight and obese]. / Elaboración y validación de un nuevo cuestionario de hábitos alimentarios para pacientes con sobrepeso y obesidad.

INTRODUCTION: When designing a comprehensive and personalized treatment for weight control, the information provided by obese patients on their dietary habits must be gathered correctly. Our objective was to develop and validate a new questionnaire on dietary habits for overweight and obese patients that could be used clinically. MATERIAL AND METHODS: The new questionnaire was developed and validated through a three-step process. Firstly, an existing questionnaire was reviewed. Secondly, a new questionnaire was developed, which included new items. Thirdly, scales to aid interpretation of the results in clinical practice were developed. Construct validity was assessed using factor analysis. The internal consistency reliability was analyzed. RESULTS: The validity and reliability of the new questionnaire was confirmed. The values of the patients' responses to the new questionnaire were related to variables such as age, sex, body mass index, and whether or not the patients were under treatment for hypertension, diabetes mellitus or dyslipidemia. CONCLUSION: The validity and reliability of this questionnaire and the scales that aid their interpretation make it a useful tool for initial assessment and monitoring of changes in eating habits in response to treatment both individually and collectively in the Spanish population.

Introducción En el diseño de un tratamiento integral y personalizado para el control del peso es necesario que la recogida de información que nos da el paciente obeso sobre sus hábitos se haga de manera correcta. Nuestro objetivo fue la elaboración y validación de un nuevo cuestionario de hábitos alimentarios para pacientes obesos y con sobrepeso que pudiera ser utilizado en la clínica. Material y métodos La elaboración y validación del nuevo cuestionario se realizó a través de un proceso en el que primero se analizó un cuestionario ya existente; en segundo lugar se elaboró el nuevo cuestionario incluyendo nuevos ítems, y en tercer lugar se elaboraron baremos para su interpretación en la clínica. Se valoró la validez de constructo mediante un análisis factorial. Se analizó la fiabilidad de consistencia interna. Resultados Se confirmaron la validez y fiabilidad del nuevo cuestionario. Los valores de las respuestas de los pacientes al nuevo cuestionario se relacionan con variables como la edad, el sexo, el índice de masa corporal, y con el hecho de estar o no en tratamiento para la hipertensión arterial, la diabetes mellitus o la dislipemia. Conclusión La validez y fiabilidad de este cuestionario y los baremos que facilitan su interpretación lo hacen un instrumento útil para la valoración inicial y el seguimiento de la modificación de hábitos nutricionales en respuesta al tratamiento tanto de manera individual como colectiva a la población española (AU)
