Validation of a Turkish Version of the Athlete Food Choice Questionnaire.

There are multiple influences on food choice for athletes. The aim of this study was to assess the validity and reliability of a Turkish Athlete Food Choice Questionnaire (Turkish-AFCQ) and describe the main factors influencing food choices. A multi-step process of language and content validation, Explanatory Factor Analysis, Confirmatory Factor Analysis, and test-retest reliability were used to examine factorial structure and construct validity (convergent and discriminant) and reliability (internal and external). The translated Turkish-AFCQ was administered to 446 athletes (59% male, median age = 21 years) from a variety of sports. The original nine-factor structure was validated, external reliability was acceptable, and all factors achieved acceptable discriminate validity. Convergent validity and internal reliability received tenable-ideal ratings for seven and eight factors, respectively. Interpretation and future application are discussed for low-performing factors 'food and health awareness' and 'influence of others'. The factor most frequently (never 1-always 5) influencing choices was 'performance' (Md = 4.33) and the least was both the 'influence of others' and 'food values and beliefs' (Md = 2.67). The Turkish-AFCQ can be used to expand researchers' and practitioners' understanding of the relative influence multiple factors have on food choices, and this study provides a model for AFCQ linguistic translation and validation.

The feasibility of anthropometric measurements for evaluation of abdominal obesity in patients with autosomal dominant polycystic kidney disease: A cross-sectional study.

Introduction: Introduction: total kidney volume (TKV) increases in patients with autosomal dominant polycystic kidney disease (ADPKD), which perturbs anthropometric measurements. Objectives: the primary objectives were to investigate the accuracy of waist circumference (WC) and waist-to-hip ratio (WHR) for determining abdominal obesity in patients with ADPKD by comparison with magnetic resonance images. The secondary objectives were to investigate the associations of energy/macronutrient intake with WC and WHR. Methods: sixty patients with ADPKD were recruited from a nephrology outpatient clinic in this cross-sectional study. Main outcome measures were: TKV, total subcutaneous fat (TSF), total intraperitoneal fat (TIF), WC, WHR, body mass index (BMI), skinfold thickness (SFT), and energy/macronutrient intake. Results: mean age was 48.6 ± 11.3 years, 38 of 60 were women, median TKV was 1486 (IQR, 981-2847) mL. The patients classed as obese by the BMI had higher WC, TSF, TIF, and SFT than did non-obese; however, WHR was similar in obese and non-obese men. In the all-patients group, the WHR of obese and non-obese patients were also similar. TKV was positively correlated with WC and WHR in women, but not in men. In the multivariate analysis, TKV was an independent factor affecting WC and WHR in women. Dietary fat intake was similar in groups with and without abdominal obesity according to WC and WHR. Conclusions: in women with ADPKD, WC and WHR may not be accurate anthropometric measurements for evaluation of abdominal obesity; however, they may be associated with TKV.

Introducción: Introducción: el volumen total del riñón (TKV) crece en los pacientes con enfermedad poliquística autosómica dominante del riñón (ADPKD), la cual perturba las mediciones antropométricas. Objetivos: los principales objetivos eran investigar la precisión de la circunferencia de la cintura (WC) y del cociente cintura-cadera (WHR) para determinar la obesidad abdominal en pacientes con ADPKD en comparación con imágenes de resonancia magnética. Los objetivos secundarios eran investigar las asociaciones entre consumo de energia/macronutrientes y WC y WHR. Métodos: sesenta pacientes con ADPKD fueron reclutados por una clínica ambulatoria de nefrología en este estudio transversal. Las medidas resultantes principales fueron: TKV, grasa subcutánea total (TSF), grasa intraperitoneal total (TIF), WC, WHR, índice de masa corporal (BMI), espesor del pliegue cutáneo (SFT) y consumo de energía/macronutrientes. Resultados: la edad media era de 48,6 ± 11,3 años, 38 de 60 eran mujeres, la media de TKV era 1486 (IQR: 981-2847) mL. Los pacientes clasificados como obesos por el BMI tenían niveles más altos de WC, TSF, TIF and SFT que los no obesos; sin embargo, el WHR era similar en los hombres obesos y no obesos. En el grupo de todos los pacientes, el WHR de obesos y no obesos era también similar. El TKV se correlacionó positivamente con la WC y el WHR en las mujeres pero no en los hombres. En el análisis multivariado, el TKV era un factor independiente que afectaba a la WC y el WHR en las mujeres. La ingesta de grasas en la dieta era similar en los grupos con y sin obesidad abdominal de acuerdo con la WC y el WHR. Conclusiones: en las mujeres con ADPKD, la WC y el WHR quizá no son las medidas antropométricas más apropiadas para evaluar la obesidad abdominal; sin embargo, quizá esté relacionada con el TKV.
