ABSTRACT
Gut microbiota is a group of microorganisms that are deposited throughout the entire gastrointestinal tract. Currently, thanks to genomic tools, studies of gut microbiota have pointed towards the understanding of the metabolism of important bacteria that are not cultivable and their relationship with human homeostasis. Alterations in the composition of gut microbiota could explain, at least in part, some epidemics, such as diabetes and obesity. Likewise, dysbiosis has been associated with gastrointestinal disorders, neurodegenerative diseases, and even cancer. That is why several studies have recently been focused on the direct relationship that these types of conditions have with the specific composition of gut microbiota, as in the case of the microbiota-intestine-brain axis. In the same way, the control of microbiota is related to the diet. Therefore, this review highlights the importance of gut microbiota, from its composition to its relationship with the human health-disease condition, as well as emphasizes the effect of probiotic and prebiotic consumption on the balance of its composition.
ABSTRACT
The aim of this work was to compare the distribution of disordered eating behaviors (DEB) in Mexican adult patients, with and without type 2 diabetes. A cross-sectional descriptive and comparative field research was carried out in a sample of 169 subjects (54% females; 46% males) with a mean age of 47.9 years. The sample was matched in two groups: patients with type 2 diabetes and patients without diabetes. DEB were assessed with a valid Mexican scale named EFRATA (Escala de Factores de Riesgo Asociados a Trastornos Alimentarios). Results confirmed significant differences in food and weight concern (t = 4.15, df 152.09, p = 0.000), normal eating behavior (t = 4.03, df 151.45, p = 0.000) and emotional eating (t = 1.93, df 160.76, p < 0.05), EFRATA's factors in which diabetic subjects obtained higher values in comparison with no diabetic patients. Subjects without diabetes achieved higher value only in binge eating behavior with statistically significant difference (t = 2.11, df 128.8, p < 0.05) in contrast with diabetic patients. Since these findings have been open the possibility to propose specific strategies that encourage healthy eating behaviors, both in adult patients with and without diabetes.
El objetivo de este estudio consistió en comparar la distribución de conductas alimentarias de riesgo en pacientes mexicanos adultos con y sin diabetes tipo 2. Se efectuó un estudio de campo de tipo descriptivo y comparativo en una muestra de 169 sujetos (54% mujeres; 46% hombres) con una media de edad de 47,9 años. Los sujetos fueron divididos en 2 grupos: pacientes con diabetes y pacientes sin diabetes. Para medir las conductas alimentarias de riesgo se empleó la Escala de Factores de Riesgo Asociados a Trastornos Alimentarios (EFRATA). Los resultados confirmaron diferencias significativas en preocupación por el peso y la comida (t = 4,15, df 152,09, p = 0,000), conducta alimentaria normal (t = 4,03, df 151,45, p = 0,000) y en comer por compensación psicológica (t = 1,93, df 160,76, p < 0,05), factores de la EFRATA en los que los pacientes diabéticos registraron valores más altos. En contraste con los pacientes diabéticos, los sujetos sin diabetes alcanzaron el valor más alto con diferencia estadísticamente significativa en el factor comer compulsivo (t = 2,11, df 128,8, p < 0,05). A partir de estos hallazgos se abre la posibilidad de proponer estrategias puntuales que favorezcan conductas alimentarias saludables, tanto para pacientes adultos diabéticos como sin diabetes.
ABSTRACT
OBJECTIVE: To determine the distribution and relation of risk factors: biological (body mass index (BMI), sexual maturity) psychological (eating behaviours, body unsatisfied), and sociocultural (publicity influence and distress with body shape) factors associated to eating disorders in Mexican pubescent from Hidalgo, Mexico. MATERIAL AND METHODS: A field transversal descriptive and correlational design was carried away with a probabilistic sample of 2194 pubescent (males 48%; females 52%), between 11 and 15 years (X = 13.2; DE = 1.03) junior high students. A self-report questionnaire on eating behaviours, body image, sociocultural factors and sexual maturity was applied. BMI was obtained from each subject. RESULTS: The date showed that the majority (57% of females and 61.6% of males) was unsatisfied with their body shape as well as important percentages of distress of body shape (28% females; 14% males). Both females (25%) and males (16%) eliminate food times. About restrictive dieting the percentage between males (6%) and females (5.2%) were very similar. Only females showed preoccupation about weight and food (17.2%). As a BMI increased, unsatisfied with body shape (r = 0.552, p < 0.01) increased too. As well increased influence of publicity, distress of body shape increased too (r = 0.586, p < 0.01). These facts are deemed relevant to the etiophatology, prevention and treatment of eating disorders in Mexican pubescent.
