| 目的: 探讨不同体质指数(BMI)水平的血胆固醇边缘升高患者的膳食特征,为个性化营养干预提供依据。方法: 选取2023年10月至12月在南通大学附属东台医院体检的81例血胆固醇边缘升高患者,使用InBody-770分析体成分,采用连续3 d 24 h膳食回顾法和简化版国际体力活动问卷收集膳食和体力活动数据。根据BMI水平分为正常、超重和肥胖组,分析并比较不同组别膳食特征的差异。结果: 研究对象的总体力活动的代谢当量为1 395.0(729.8,2 163.0) min·周-1,伴有内脏脂肪堆积。参照《中国居民膳食指南(2022)》建议,超过50%的研究对象谷类摄入偏高,薯类和蔬菜摄入适中。血胆固醇升高伴超重组[(586.8±71.4) kcal]和肥胖组[(604.4±73.5) kcal]的脂肪供能显著高于正常组[(544.3±80.1) kcal,P=0.046],但蛋白质与碳水化合物摄入差异无统计学意义(P>0.05)。血胆固醇升高伴超重或肥胖组患者的膳食纤维摄入量低于正常BMI者,总脂肪酸、饱和脂肪酸及单不饱和脂肪酸摄入较高(P<0.05)。结论: 东台市血胆固醇边缘升高患者的膳食结构不均衡,谷类、水果、蛋类和奶制品的摄入亟待改善;超重及肥胖组志愿者脂肪摄入及脂肪供能比偏高,膳食纤维摄入不足,需加强个性化营养干预。 |
| Objective: To investigate the dietary characteristics of patients with borderline hypercholesterolemia at different body mass index(BMI) levels and provide a basis for personalized nutritional interventions. Methods: A total of 81 patients with borderline hypercholesterolemia who underwent health examinations at Dongtai Hospital, Affiliated to Nantong University, from October to December 2023 were included. Body composition was analyzed using the InBody-770 system. Dietary intake and physical activity data were collected through a three-day 24-hour dietary recall and the short-form International Physical Activity Questionnaire. Participants were categorized into normal weight, overweight, and obese groups based on BMI, and differences in dietary characteristics among these groups were analyzed. Results: The median total weekly physical activity was 1 395.0(729.8, 2 163) min·week-1, accompanied by visceral fat accumulation. Compared with the recommendations of "Dietary Guidelines for Chinese Residents(2022)", more than 50% of participants consumed cereals in excess, while intake of tubers and vegetables was moderate. Energy intake from fat was significantly higher in the overweight[(586.8±71.4) kcal] and obese[(604.4±73.5) kcal] groups than in the normal weight group[(544.3±80.1)kcal](P=0.046), whereas protein and carbohydrate intake showed no significant differences(P>0.05). Patients with borderline hypercholesterolemia who were overweight or obese had lower dietary fiber intake, while total fatty acids, saturated fatty acids, and monounsaturated fatty acids were significantly higher compared with those with normal BMI(P<0.05). Conclusion: The dietary structure of patients with borderline hypercholesterolemia in Dongtai is imbalanced, with suboptimal intake of cereals, fruits, eggs, and dairy products. Overweight and obese volunteers exhibit higher fat consumption and fat-derived energy ratios, alongside insufficient dietary fiber intake, underscoring the need for targeted nutritional interventions. |
