ABSTRACT
La evidencia sobre los posibles mecanismos de utilización de los ácidos grasos Omega 3 para mediar la obesidad requiere continuar con estudios clínicos con metodologías concretas. El objetivo fue evaluar mediante impedancia bioeléctrica el efecto de la suplementación de omega 3 sobre el Indicé de Masa Corporal (IMC), Índice Cintura Cadera (ICC) y composición corporal en mujeres obesas. Participaron 60 mujeres obesas adultas (IMC >30 Kg/m²) que fueron aleatorizadas en 3 grupos: Grupo 1) placebo, vitamina E (200 UI), Grupo 2) 1 g de omega 3) y Grupo 3) 2 g de omega 3. Todas recibieron dieta hipocalórica y ejercicio moderado. Se midieron; peso, IMC, índice cintura cadera y distribución grasa al inicio y cada mes por tres meses. Los resultados muestran que la suplementación con omega 3 tuvo una relación dosis respuesta disminuyendo significativamente el peso, IMC y la masa grasa total, en comparación con el grupo control. Estos efectos dependieron del tiempo y cantidad de Omega 3 suplementada, cuando se ajustó por el grado de cumplimiento de ejercicio, apego a la dieta y edad. Concluimos que la suplementación con Omega 3 es un coadyuvante eficaz en el manejo de la obesidad en mujeres premenopáusicas.
Evidence on the possible mechanisms for the use of Omega 3 fatty acids to mediate obesity requires clinical studies continue with specific methodologies. The aim was to assess the effect of omega-3 supplementation on Body Mass Index (BMI), Wais - Hip Index (WHI) and body composition of obese women using bioelectrical impedance. Subjects 60 premenopausal obese women (BMI > 30Kg/m²) were randomly assigned to 3 groups: Group 1) placebo, vitamin E (200 IU), group 2) 1 g of omega and group 3) 2 g of omega-3. All of them received a low calorie diet and moderate exercise. Weight, BMI, WHI, and fat distribution were measured at the beginning and every month for three months. The results show us Omega-3 supplementation significantly reduced weight, BMI, and total fat mass, compared to the control group, a dose-response effect. These effects depended on the time and amount of Omega 3 supplemented, when the degree of compliance of exercise, adherence to the diet and age were controlled. In conclusion the supplementation with omega- 3 is an efficient method in the management of obesity in premenopausal women.

Objetivo. Determinar el cambio en la hemoglobina glucosilada (HbA1c) en pacientes diabéticos tipo 2 sedentarios al realizar ejercicio aeróbico 2 o 3 veces por semana en días alternos. Se realizó en la Unidad de Medicina Familiar del Instituto Mexicano del Seguro Social en San Luis Potosí, con el diseño de un ensayo clínico controlado. Material y métodos. Se integraron dos grupos (n = 25) de ejercicio de 2 y 3 veces por semana en días alternos. Mediciones de los valores basales, 8 y 16 semanas de hemoglobina glucosilada A1c (HbA1c), capacidad aeróbica, índice de masa corporal (IMC) y cumplimiento. Resultados. No se encontró diferencia significativa en HbA1c entre los dos grupos de estudio, pero sí al comparar sus valores basales (p <0.001). No se encontró correlación significativa entre la HbA1c y el cambio de capacidad aeróbica o el IMC. El porcentaje de cumplimiento fue mayor en el grupo de 2 días de ejercicio. Conclusiones. El ejercicio aeróbico de intensidad moderada es bien tolerado, obteniendo una reducción significativa de HbA1c y se constata mejor cumplimiento en el grupo de 2 días.
OBJECTIVE: Determine the extent to which levels of glycosylated hemoglobin levels among type 2 sedentary diabetic patients change when performing aerobic exercises two or three times a week. SETTING: Mexican Institute Social Security, Family Medicine Unit, primary care level. STUDY DESIGN: Controlled clinical trial. METHODS AND SUBJETS: Two groups of 25 participants carried out a comprehensive exercise routine 2 or 3 times per week in alternate days. Measurements were done at baseline, 8 and 16 weeks. HbA1c, aerobic capacity, BMI and compliance were assesed. OUTCOME: There was no significant difference in HbA1c between the two study groups, however both groups showed lower levels of HbA1c when comparing their baseline and follow up levels (p < 0.001). No significant association was found between Hb1Ac, aerobic capacity or BMI. Compliance was higher among the group exercising 2 days. CONCLUSION: Moderate aerobic exercise was well tolerated showing a significant decrease on HbA1c even among the 2 day group.

OBJECTIVE: To compare the frequency of periodontal disease in type 1 diabetes mellitus patients with and without metabolic control, having a control group of healthy patients. MATERIAL AND METHODS: A prolective cross sectional study with simple random sampling was carried out; patients were divided in three groups: A). Forty healthy subjects, B). Twenty diabetic patients with metabolic control, and C). Twenty diabetic patients without metabolic control. The diabetic subjects were evaluated with glycosylated hemoglobin (GHb) to determine the glucose control; clinical periodontal evaluations were performed for all teeth in each subject and following indexes were included: Plaque, gingival, mobility, probing depth, attachment level, bleeding on probing, and marginal bone loss. RESULTS: The imbalance of glucose of subjects with diabetes mellitus type 1 was associated with more frequency of periodontal disease (p < 0.05). CONCLUSION: The population of type 1 diabetes mellitus with imbalance of glucose showed association with periodontal disease.
