ABSTRACT

Objetivo Determinar la frecuencia y factores de riesgo para sobrepeso y obesidad en jóvenes universitarios. Métodos Se realizó un estudio transversal analítico en 821 alumnos inscritos de la Universidad de Colima. Entre las variables analizadas se encuentran: edad, género, alcoholismo, tabaquismo y utilización de medicamentos o sustancias para control de peso. Resultados Se estudiaron 821 alumnos (380 hombres y 441 mujeres) con una edad promedio de 20,9±2,5 años. Las frecuencias de sobrepeso y obesidad en hombres fueron de 27,8 por ciento y 14,7 por ciento y en mujeres de 17 por ciento y 5,2 por ciento. En hombres el tabaquismo (OR 2,1, IC 95 por ciento 1,4-3,8;p=0,01) y etilismo (OR 2,1, IC 95 por ciento 1,2-3,6;p=0,003), estuvieron asociados a sobrepeso y obesidad. Fueron factores protectores en ambos géneros el uso de sustancias para control de peso (OR 0,4, IC 95 por ciento 0,2-0,8;p=0,01); mientras que el control dietético fue un factor protector sólo en las mujeres (OR 2,2, IC 95 por ciento 1,1- 3,4;p=0,01). Conclusiones En estudiantes universitarios, el 31,6 por ciento presentó sobrepeso y obesidad. En hombres, el tabaquismo y etilismo se asociaron a sobrepeso y obesidad. El uso de sustancias para bajar de peso y control dietético fueron factores protectores.


Objective Determining risk factor frequency regarding obesity and being overweight in university students. Methods A cross-sectional analytic study was carried out on 821 students from the University of Colima. Some variables analysed were age, gender, alcoholism, smoking and weight-control drug use. Results 821 students were included (380 male, 441 female), 20.9±2.5 average age. 27.8 percent of males were overweight and 14.7 percent suffered from obesity; this was 17 percent and 5.2 percent in females, respectively. Smoking (2.1 OR; 1.4-3.8 95 percent CI; p=0.01) and alcoholism (2.1 OR; 1.2-3.6 95 percent CI; p=0.003) were associated with being overweight and being obese. Weight-control drug use was a protective factor in both genders (0.4 OR; 0.2-0.8 95 percent CI; p=0.01); diet control was only a protective factor in women (2.2. OR; 1.1-3.4 95 percent CI; p=0.01). Conclusions 31.6 percent of university students were overweight and suffered from obesity. Smoking and alcoholism in males were associated with being overweight and suffering from obesity. Weight-control and diet-control drug use were protective factors.

ABSTRACT

Aluminium phosphide (AlP) a grain fumigant is the leading cause of intentional poisoning in North India. The mechanisms involved in toxicity are not known and there is no antidote till date. The present study was carried out to investigate the oxygen free radical generation, methemoglobinemia and effect of methylene blue treatment on survival time in rat model of AlP poisoning. AlP (50 mg/kg, intragastric) was administered in one group and the other group received AlP + Methylene Blue (MB) (0.1%, 1 mg/kg/5 min, i.v.). Malonyldialdehyde (MDA) and methemoglobin (MeHb) levels were measured at 10 and 30 min intervals. Blood MDA levels increased at 10 and 30 min after AlP exposure with simultaneous rise in MeHb levels suggesting methemoglobinemia could be due to increased oxygen free radical generation. Methylene blue caused a significant fall in both the parameters with prolongation of survival time. It is concluded that AlP causes methemoglobinemia responding to methylene blue treatment.

ABSTRACT

Se estudiaron las modificaciones antropométricas secundarias a tratamiento reductor, en 53 mujeres obesas premenopáusicas, entre 25 y 45 años. Antes y después del tratamiento se midieron las circunferencias del brazo, abdomen, cintura, cadera, muslo y pierna y los pliegues cutáneos tricipital, bicipital, suprailíaco, subescapular, abdominal y de la pierna. Estos últimos promediaron sobre el 75 percentilo. Las mediciones finales resultaron significativamente inferiores excepto las circunferencias de la pierna y los índices de abdomen/cadera y cintura/muslo. El peso corporal disminuyó en promedio 8,9 kg y la media de los pliegues por debajo del percentilo 75: el peso graso relativo disminuyó 18.3 por ciento y el índice de masa corporal 11 por ciento. El análisis de componentes principales inicial reveló tres características de la obesidad, adiposidad general; distribución tronco/extremidades y distribución superior/inferior. El tratamiento modificó las características de la distribución de la grasa de las obesas y logró reducir significativamente los índices predictivos de morbilidad asociados a obesidad
