目的探讨超重男性青年膳食产能营养素的摄入特点。方法在黑龙江省哈尔滨市某高校招募82名男性青年志愿者进行连续3 d 24 h回顾性膳食调查,测量其身高、体重、腰围、臀围、腰臀比、体脂比,同时采集空腹静脉血测定其血糖、血脂等生化指标。结果超重组与正常组男性青年摄入总能量比较,差异无统计学意义（P〉0.05）;但在能量来源方面,超重组脂肪供能[（29.83±5.81）%]、动物性食品供能[（28.12±8.08）%]和动物性脂肪供能[（44.76±15.80）%]均高于正常组的[（26.18±4.95）%]、[（24.30±7.98）%]和[（35.55±15.89）%],差异均有统计学意义（均P〈0.05）;3餐供能方面,超重组晚餐提供能量为（40.19±6.24）%,高于正常组的（36.18±7.18）%,差异有统计学意义（t=2.706,P=0.008）;血清生化检测结果显示,超重组血清高密度脂蛋白胆固醇（HDL-C）为（1.21±0.24）mmol/L,低于正常组的（1.36±0.28）mmol/L,低密度脂蛋白胆固醇（LDL-C）、甘油三酯（TG）、总胆固醇（TC）和游率脂肪酸（NETA）分别为（2.62±0.63）mmol/L、（1.37±0.98）mmol/L、（4.72±0.85）mmol/L和（693.33±219.97）μmol/L,均高于正常组的（2.14±0.59）mmol/L、（0.94±0.39）mmol/L、（4.27±0.83）mmol/L和（493.68±189.30）μmol/L,差异均有统计学意义（P〈0.05）。结论超重男性青年应减少脂肪尤其是动物脂肪摄入,可预防肥胖及其他代谢性疾病的发生。

英文摘要：

Objective To explore the characteristics of energy nutrients intake in overweight young men. Methods Eighty-two young men aged 19 -28 years were divided into overweight group （n =42） and normal-weight group （n =40） based on their body mass index（BMI） （BMI ≥25.0 kg/cm2 for overweight and BMI ≥ 18.5 kg/cm2 and ≤23.9 kg/cm2 for normal weight）. The dietary intake was assessed with 24-hour recall method in a successive 3-day. Anthropometric parameters such as height, weight, waist circumference, hip circumference, body fat, and blood pressure were measured. Fasting blood glucose, triglyceride （ TG ）, total cholesterol （ TC ）, high-density lipoprotein cholesterol （HDL-C）, low-density lipoprotein cholesterol （LDL-C） and, non-esterified fatty acid （NEFA） in serum were also detected. Results Compared with the normal-weight, the overweight had a nonsignificantly higher total energy intake （P 〉0.05） ,but a higher animal food consumption（28.12 ±8. 08% ） and fat intake（29. 83 ±5.81% ） ,especially for ani- mal fat （44. 76 ± 15. 80% higher than that of the normal-weight） （P 〈0. 05）. There were significant differences in serum lipids between the two groups（P 〈0.05 for all）. Thereinto the overweight had higher LDL-C（2. 62 ±0. 63 mmol/L）, TG （ 1.37 ±0. 98 mmol/L） ,TC（4. 72 ±0. 85 mmol/L） ,and NEFA（693.33 ±219. 97 mmol/L） than those of the nor- mal-weight（2. 14 ±0. 59 retool/L,0. 94 ±0. 39 mmol/L,4. 27 ±0. 83 mmol/L, and 493.68 ±189. 30 μmol/L） ,but low- er HDL-C. Conclusion The intake of dietary fat, especially animal fat,in overweight men should be adjusted for the im- provement of obesity to prevent related metabolite diseases.
