The present study evaluated the effects of food and alcohol intake on the nutritional and metabolic status of male and female periadolescent rats submitted to single (15%) and multiple (10%, 20%, 30%) concentrations of hydroalcoholic solutions of sugar-based alcohol associated with a feed mixture. Thirty-six periadolescent Wistar rats were used and randomly arranged into three groups: Group A (control; 0% ethanol; six males and six females), Group B (15% ethanol; six males and six females), and Group C (10%, 20%, and 30% ethanol; six males and six females). Food consumption, body weight, water intake (mL), ethanol intake (g/kg/day), ethanol preference in relation to water and different concentrations, and serum biochemical dosages (glucose, total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein (HDL) cholesterol, very low-density lipoprotein fraction, triglycerides, cholesterol/HDL [CT/HDL], albumin) were analyzed. Males from Group C ingested more feed than females, which consumed reducing amounts throughout the weeks studied. Males also had heavier body weight, which increased throughout the experimental period. The animals ingested more water (females ingested more than males) in the first experimental week. Group C had a higher ethanol intake and greater preference for ethanol over water in both genders than Group B, which decreased over the subsequent weeks. Serum glucose was lower in Group A, whereas the CT/HDL ratio was lower in Group C. These findings allow the conclusion that nutritional and metabolic impact resulting from alcohol intake is different between genders and between the different forms in which the drug is offered. It is important to warn the population about the concentrations of alcohol intake, which may influence the growth and development of adolescents, thereby compromising their quality of life.
本研究评估了食物和酒精摄入量对接受单一(15%)和多种(10%、20%、30%)浓度的糖基酒精水醇溶液与饲料混合物的青春期前后雄性和雌性大鼠营养和代谢状况的影响。使用了36只青春期前后的Wistar大鼠,并将其随机分为三组:A组(对照组;0%乙醇;6只雄性和6只雌性)、B组(15%乙醇;6只雄性和6只雌性)和C组(10%、20%和30%乙醇;6只雄性和6只雌性)。分析了食物消耗量、体重、水摄入量(毫升)、乙醇摄入量(克/千克/天)、相对于水和不同浓度的乙醇偏好,以及血清生化指标(葡萄糖、总胆固醇、低密度脂蛋白胆固醇、高密度脂蛋白(HDL)胆固醇、极低密度脂蛋白部分、甘油三酯、胆固醇/HDL [CT/HDL]、白蛋白)。C组的雄性比雌性摄入更多的饲料,而雌性在整个研究周内摄入量逐渐减少。雄性体重也更重,在整个实验期间体重增加。在第一个实验周,动物摄入更多的水(雌性比雄性摄入更多)。C组的乙醇摄入量更高,且在两性中对乙醇的偏好均高于B组,且在随后几周有所下降。A组的血清葡萄糖较低,而C组的CT/HDL比值较低。这些发现可以得出结论,酒精摄入对营养和代谢的影响在性别之间以及药物提供的不同形式之间是不同的。重要的是要提醒人们注意酒精摄入的浓度,这可能会影响青少年的生长发育,从而损害他们的生活质量。
