Translation and cross cultural adaptation of the questionnaire "Quality of Alimentation" for brazilian portuguese. / Tradução e adaptação transcultural do questionário "Quality of Alimentation" para o português brasileiro.

PURPOSE: We aimed to provide translation and cultural adaptation of the questionnaire "Quality of Alimentation" from English to Brazilian Portuguese. METHODS: The transcultural translation process consisted of the following steps: translation of the original English version to Portuguese by two bilingual translators native in the targeted language; Reverse translation by two translators native in the original language; Review of reverse translation; Review of the Portuguese version from the questionnaire by a local committee of experts in bariatric surgery; Pre-trial to evaluate of clarity, comprehension, and overall acceptability by the target population. RESULTS: In its final Portuguese version, the questionnaire "Quality of alimentation" was found to be of clear comprehension and easy applicability. CONCLUSION: The questionnaire's translation and cultural adaptation for Brazilian Portuguese represents an important step towards improving food tolerance evaluation following bariatric surgery. Further studies are however necessary for validation of its psychometric properties in Brazil.

Evaluation of factors that may influence in the insufficient weight loss in patients after two years of Roux-en-Y gastric bypass.

INTRODUCTION: bariatric surgery is a favorable option for the treatment of obesity, resulting in long-term weight loss. OBJECTIVES: to analyze whether feeding behavior, evaluated by caloric intake, dietary preferences and tolerance, can be considered as a determinant factor for weight loss in obese patients submitted to Roux-en-Y gastric bypass (RYGB). METHODS: cross-sectional study of 105 patients with at least two years post-RYGB surgery with a preoperative body mass index (BMI) of ≥ 35 kg/m². Caloric intake was evaluated by 24-hour dietary recall and 3-day dietary intake record; dietary habits, by a qualitative dietary frequency questionnaire; and food tolerance, with a validated questionnaire. Multiple logistic regression was used for statistical analysis. RESULTS: the majority of the 105 participants were female (84%). The mean age was 43.3 ± 11.4 years in the success group (n = 64) and 43.4 ± 10.7 years in the failure group (n = 41). Preoperative BMI was not associated with the outcome. Mean caloric intake did not show significant differences between groups: 24 hours recall, p = 0.27; 3-day record, p = 0.95. The frequency of weekly consumption of desserts was twice as high in the success group. Only two patients in the success group presented daily vomiting. CONCLUSION: the factors that determine the failure of weight loss have not yet been fully elucidated. Caloric intake was not a determining factor of failure, and insufficient weight loss was more prevalent in patients who ceased to lose weight earlier.

Introducción: la cirugía bariátrica es una opción favorable para el tratamiento de la obesidad, resultando a largo plazo en pérdida de peso. Objetivos: analizar si el comportamiento alimentario, evaluado por la ingesta calórica, las preferencias y las tolerancias alimentarias, puede ser considerado un factor determinante de los resultados de pérdida de peso en pacientes obesos sometidos a bypass gástrico en Y de Roux (BPGYR). Métodos: se realizó un estudio de cohorte retrospectivo con 105 pacientes sometidos a cirugía de BPGYR, con índice de masa corporal (IMC) preoperatorio ≥ 35 kg/m² y, como mínimo, dos años de postoperatorio. La ingesta calórica fue evaluada por el recordatorio alimentario de 24 horas y el registro alimentario de tres días. Para la evaluación de los hábitos alimentarios se empleó un cuestionario cualitativo de frecuencia alimentaria y para la tolerancia alimentaria, un cuestionario validado. Resultados: la mayoría de los participantes eran del sexo femenino (84%). La edad promedio fue de 43,30 ± 11,39 años en el grupo éxito y de 43,39 ± 10,73 años en el grupo sin éxito. El IMC preoperatorio no presentó influencia sobre el resultado final. El promedio de ingesta calórica no mostró diferencia significativa entre los grupos estudiados (R 24 h, p = 0,27; registro del diario alimentario, p = 0,95). La frecuencia del consumo semanal de dulces fue dos veces mayor en el grupo éxito. Apenas dos pacientes del grupo éxito presentaban vómitos diarios. Conclusión: los factores que determinan la falta de éxito en la pérdida de peso aún no están bien esclarecidos. La ingesta calórica no fue un factor determinante para no obtener éxito y la pérdida de peso insuficiente fue más prevalente en los pacientes que dejaron de perder peso más temprano

Análise bioética nas indicações de cirurgia bariátrica em crianças e adolescentes / Bioethical analysis of indicating bariatric surgery for children and adolescents / Análisis de la bioética para las indicaciones de cirugía bariátrica en niños y adolescentes

A cirurgia da obesidade vem sendo reconhecida como tratamento eficiente para perda de peso e melhora das comorbidades a ela associadas. Em adultos, os riscos e benefícios de curto e longo prazo já são bem conhecidos na literatura; contudo, em crianças e adolescentes não existem dados precisos. Por envolver mudanças significativas nos hábitos de vida e na alimentação, a decisão pelo tratamento cirúrgico para essa população ainda é delicada e necessita da participação de toda a equipe médica, além do envolvimento familiar. Para isso, o médico responsável deve conhecer os principais aspectos bioéticos implicados na questão a fim de ponderar sobre os passos necessários para conduzir melhor os casos em que a cirurgia bariátrica é a opção mais adequada.

Bariatric surgery is becoming more and more established as an effective form of weight loss and method of treating comorbidities related to this condition. The short and long-term risks and benefits for adults have been well documented in literature, but no accurate data exists for children and adolescents. Given the significant changes in lifestyle habits and diet involved, the decision to undergo surgical treatment is a delicate one, requiring the participation of the entire medical team and the patient’s family. For this reason the doctor in charge must be aware of the major bioethical aspects involved, and th steps required to effectively manage cases were bariatric surgery is the preferred option.

Food tolerance in patients submitted to gastric bypass: the importance of using an integrated and interdisciplinary approach.

BACKGROUND: Under the restrictive component, patients undergoing gastric bypass may have food intolerance with or without complications. METHODS: This study used quantitative, analytical, observational methodology with patients submitted to Roux-en-Y gastric bypass without the placement of a ring at Hospital Universitário do Rio Grande do Norte in the city of Natal, Brazil between July 2005 and August 2010. Out of 176 patients monitored after surgery by the interdisciplinary team, 47 took part in the study. Two questionnaires were applied to participants: one elaborated by Suter et al. and previously validated for assessment of food tolerance and another to characterize schooling and socioeconomic status. Evaluation of food tolerance considered patient satisfaction with eating, most accepted food types, and frequency of vomiting and/or regurgitation. After application of the first questionnaire, a score was generated, characterizing food intolerance. RESULTS: Of the 47 patients evaluated, 85.1% classified their degree of food satisfaction as good or excellent. Red meat was the most cited as being difficult to ingest (38.3%), representing a significant impact on overall tolerance level (P < 0.001); 48.9% of participants exhibited rare episodes of vomiting, which resulted in a mean food tolerance score of 23.02 (2.87 ± SD). Moreover, socioeconomic status showed a significant correlation with tolerance level (P = 0.032). CONCLUSIONS: The degree of food tolerance observed in the study sample was better than that obtained in other investigations using similar methodology. The questionnaire proved to be useful in evaluating food quality and comparing postoperative results. Socioeconomic status was correlated with food tolerance level.
