Riesgo de trastornos alimentarios y perfil antropométricos en modelos profesionales de México / Risk of eating attitudes and anthropometric profile among professional fashion models of Mexico

Objective: The aim of this study was to compare the risk of Eating Disorders Behaviour (EDB), and its anthropometric profile, physical activity and alimentary intake between Mexican fashion models (FM) and control women Methods: We included 50 FM and 50 control women, of the same social group, all over 18 years old, from Guadalajara, Mexico, matched by age. We evaluated the risk of EDB with the Eating Attitudes Test (EAT-26); the anthropometric measures were taken according to the criteria of the International Society for the Advancement of Kinanthropometry (ISAK), 24-hour recall to estimate energy intake and physical activities. Results: The risk prevalence of EDB was 10% for both groups. The mean and standard deviation of the percentage of body fat in FM was 22,4±2, lower than in the controls (27,8±4, p<0.001). There were no differences in anthropometric measurements in women with and without risk of EDB, except in the weight (FM without risk of EDB 56,3±3 kg and 59,9±3 kg with risk of EDB (p<0.02). Caloric intake in women with risk of EDB reduced was 1094±208 kcal in FM versus 1269±435 kcal in control woman. Conclusion: The anthropometric measurements, alimentary intake and previous history of eating disorders, suggests that FM of Mexico are a vulnerable population for eating disorder.

Objetivo: Comparar el riesgo de trastornos de la conducta alimentaria (TCA), perfil antropométrico, actividad física e ingesta alimentaria entre las mujeres mexicanas dedicadas al modelaje profesional (MP) con mujeres control. Métodos: Se incluyeron 50 MP y 50 mujeres controles, del mismo grupo social, mayores de 18 años, de Guadalajara, México, pareadas por edad. Se evaluó el riesgo de TCA con el test de Trastornos de Actitudes Alimentarias (EAT-26), se tomaron las medidas antropométricas de acuerdo a los criterios de la International Society for the Advancement of Kinanthropometry (ISAK). Se estimó el consumo de energía utilizando el recordatorio de 24 horas y se registró la práctica de actividades físicas. Resultados: La prevalencia de riesgo de TCA fue 10% para ambos grupos. La media y desviación estándar del porcentaje de grasa corporal en las MP fue 22,4±2,5 menor al de las controles (27,8±4,9) (p<0.001). No hubo diferencias en la medidas antropométricas en las mujeres con y sin riesgo de TCA, excepto en el peso de las MP de 56,3±3,1 kg sin riesgo de TCA y 59,9±3,6 en las con riesgo de TCA (p<0.02). La ingesta alimentaria se encontró reducida en las mujeres con riesgo de TCA con respecto a las sin riesgo, con 1094,2±208,3 kcal versus 1269,8±435,0 kcal en las MP y controles respectivamente. Conclusión: Las medidas antropométricas, la ingesta alimentaria y la historia previa de trastornos de la alimentación, sugiere que la MP de México es una población vulnerable para trastornos de la alimentación.

Composição corporal, gasto energético e ingestão alimentar em modelos brasileiras / Body composition, energy expenditure and food intake in brazilian fashion models

O objetivo desse estudo foi comparar a composição corporal, taxa demetabolismo em repouso e ingestão alimentar entre adolescentes modelos e nãomodelos. Participaram do estudo 33 modelos e 33 não modelos, de 15 a 18 anos,pareadas por idade e IMC. A avaliação da composição corporal foi realizada pormeio da técnica de pletismografia. A taxa de metabolismo em repouso (TMR) foiobtida pelo método da calorimetria indireta e a avaliação da ingestão alimentarfoi realizada por meio de um registro alimentar de 3 dias alternados. Não houvediferença estatisticamente significante em relação aos valores médios de percentualde gordura corporal entre os grupos estudados (p>0,05). Entretanto, ao classificar asadolescentes quanto ao percentual de gordura corporal, observou-se que nenhumamodelo apresentou percentual de gordura corporal menor do que 15%, enquanto15,2% das adolescentes não modelos apresentaram baixo percentual de gorduracorporal (p<0,05). Os valores de TMR (kcal/d) foram semelhantes entre modelos(1367,22) e não modelos (1309,43) (p>0,05). Em relação à ingestão de energia, observou-se que a média de ingestão energética foi 1480,93kcal ± 582,95 e 1973,00kcal± 557,63 entre modelos e não modelos, respectivamente (p=0,001). Conclui-se queas modelos, em sua maioria, apresentaram composição corporal dentro dos valoresconsiderados normais para esta fase da vida. Os valores de TMR foram similaresentre os grupos. Entretanto, a ingestão energética (kcal) foi menor entre as modelosem relação às adolescentes não modelos.

The objective of this study was to compare body composition, restingmetabolic rate (RMR) and food intake between adolescent fashion models and nonmodels.Thirty-three models and 33 non-models ranging in age from 15 to 18 years andmatched for age and BMI participated in the study. Body composition was evaluated byplethysmography. RMR was determined using an indirect calorimetry method and foodintake was evaluated based on three-day food records obtained on alternate days. Nosignificant difference in mean body fat percentage was observed between groups (p>0.05).However, when the adolescents were classified according to body fat percentage, noneof the models presented a body fat percentage lower than 15%, whereas 15.2% of thenon-models presented a low body fat percentage (p<0.05). RMR values (kcal/day) weresimilar in models (1367.22) and non-models (1309.43) (p>0.05). Mean energy intake was1480.93 ± 582.95 kcal in models and 1973.00 ± 557.63 kcal in non-models (p=0.001).In conclusion, most models presented a body composition within the limits considered tobe normal for this phase of life. RMR was similar in the two groups. However, energyintake was lower among adolescent models compared to non-models.
