Descuento sexual y conductas sexuales arriesgadas en una muestra de adultos jóvenes de Colombia / Sexual Discounting and Sexual Risk Behavior in a Sample of Young Adults from Colombia / Desconto sexual e comportamento sexual de risco em uma amostra de jovens adultos da Colômbia

El objetivo del presente trabajo fue describir la tasa de descuento sexual y evaluar la relación entre el autorreporte de conductas sexuales arriesgadas (csa) y el descuento sexual en una muestra de adultos jóvenes en Colombia. Para esto, se realizó una investigación no experimental de corte transversal y correlacional. Ciento treinta y seis participantes fueron sometidos a un cuestionario de autorreporte de conductas de riesgo sexual, a la tarea de descuento sexual (sddt) y al cuestionario de elección monetaria (mcq). Los análisis de la curva de descuento sexual demuestran que el valor de la opción de tener sexo seguro disminuye con el in-cremento en la demora en la obtención de un condón (i. e., descuento sexual). Adicionalmente, se observa que el grado de descuento sexual está asociado con csa, como el número de parejas sexuales y el número de relaciones sexuales en los últimos tres meses, y que hay una diferencia en el patrón de descuento sexual entre hombres y mujeres.

The goal of this study was to describe the rate of sexual discounting and its relation with the self-report of sexual risk behavior in a sample of young adults from Colombia. To achieve this goal, a correlational cross-sectional non-experimental study was done. One hundred thirty six young adult participants responded to a sexual risk behavior self-report questionnaire, a sexual delay discounting task (sddt), and a monetary choice questionnaire (mcq). The results suggest that the value of the safe sex option decreases with the delay to obtain a condom (i. e., sexual discounting). Additionally, it was observed that the sexual discounting rate was associated with the self-report of sexual risk behavior, like, the number of sexual partners and sexual encounters in the last three months. It was also observed a different pattern of sexual discounting between men and women

O objetivo deste estudo foi descrever a taxa de desconto sexual e avaliar a relação entre o autorrelato de com-portamentos sexuais de risco (csr) e o desconto sexual em uma amostra de jovens adultos na Colômbia. Para isso, foi realizada uma investigação não experimental, transversal e correlacional. 136 participantes foram submetidos a um questionário de comportamentos se-xuais de risco autorreferidos, à tarefa de desconto sexual (sddt) e ao questionário de escolha monetária (mcq). As análises da curva de desconto sexual mostram que o valor da opção de praticar sexo mais seguro diminui com o aumento do atraso na obtenção do preservativo (ou seja, desconto sexual). Adicionalmente, observa-se que o grau de desconto sexual está associado à csr, assim como o número de parceiros sexuais e o número de relações sexuais nos últimos 3 meses, e que existe uma diferença no padrão de desconto sexual entre homens e mulheres.

Disminución de la grasa corporal mediante ejercicio físico intermitente de alta intensidad y consejería nutricional en sujetos con sobrepeso u obesidad / Effects of 12 sessions of high intensity intermittent training and nutrition counseling on body fat in obese and overweight participants

Background: The search of efficient exercise alternatives to treat obesity is worthwhile. Aim: To demonstrate the effect of high intensity intermittent exercise on body fat reduction in overweight and obese subjects. Material and Methods: A group of 65 overweight and obese adult subjects (25 men), aged 18-65 years, participated during 12 sessions in a high intensity physical exercise program, 3 days/week. Weight, height and body fat was measured before and after the intervention by bioimpedance. Each session consisted of 1 min stationary cycling exercise at high intensity, followed by 2 min inactive rest. This cycle was repeated 10 times, thus the method is called 1*2*10. Results: There was a significant reduction of body fat of -1.88 ± 2.8 and -3.44 ± 2.7 kg, in women and men, respectively (p < 0.05). Conclusions: The 1*2*10 training protocol lasting 12 weeks in association with nutrition counseling is effective in reducing body fat in overweight persons.
