The aim of the study was to evaluate the ability of a low carbohydrate diet score (LCD) to predict the occurrence of the metabolic syndrome (MetS) and its components in a group of Tehrani children and adolescents after 3.6 years of follow-up.
Diet scores were calculated using a validated semi-quantitative food frequency questionnaire for participants aged 6-19 years, selected from the Tehran Lipid and Glucose Study cohort. The LCD was calculated based on intake of carbohydrate, monounsaturated fatty acids, refined grains and vegetable protein intake, expressed as a percentage of energy as well as fiber, n3/n6 polyunsaturated fatty acids and glycemic load. The higher the score, the more closely the participant's diet followed the pattern of LCD. The incidence of MetS and its components was calculated three years later.
The mean age of the participants was 13.8 ± 3.6 years and 45.4% were boys. The incidence rates of MetS, high blood pressure, high triglycerides, low HDL-C, abdominal obesity, and high blood glucose were 7.5%, 11%, 15%, 6.9%, 18.3%, and 12.3%, respectively. Compared to those in the lowest quartile of LCD score, after adjusting for age, sex, physical activity, and energy intake, participants in the highest quartile of LCD score had odds ratios of 0.74 (95% CI: 0.24-2.28), 1.16 (95% CI: 0.47-2.81), 0.55(95% CI: 0.21-1.44), 0.49 (95% CI: 0.11-2.08), 0.91 (95% CI: 0.42-1.98), and 1.28 (95% CI: 0.51-3.20) with the incidence of MetS, high blood pressure, high triglycerides, low HDL-C, abdominal obesity, and high blood glucose.
No association was found between LCD and the incidence of MetS or its components in children and adolescents in Tehran after 3.6 years of follow up.
本研究旨在评估低碳水化合物饮食评分(LCD)预测一组德黑兰儿童和青少年在3.6年随访后代谢综合征(MetS)及其组分发生情况的能力。
使用经过验证的半定量食物频率问卷,对从德黑兰血脂与血糖研究队列中选取的6至19岁参与者计算饮食评分。LCD根据碳水化合物、单不饱和脂肪酸、精制谷物和植物蛋白的摄入量计算得出,以能量百分比以及纤维、n3/n6多不饱和脂肪酸和血糖负荷表示。分数越高,参与者的饮食越符合LCD模式。三年后计算MetS及其组分的发病率。
参与者的平均年龄为13.8±3.6岁,45.4%为男孩。MetS、高血压、高甘油三酯、低高密度脂蛋白胆固醇(HDL-C)、腹型肥胖和高血糖的发病率分别为7.5%、11%、15%、6.9%、18.3%和12.3%。与LCD评分最低四分位数的参与者相比,在调整年龄、性别、身体活动和能量摄入后,LCD评分最高四分位数的参与者发生MetS、高血压、高甘油三酯、低HDL-C、腹型肥胖和高血糖的比值比分别为0.74(95%置信区间:0.24 - 2.28)、1.1(95%置信区间:0.47 - 2.81)、0.55(95%置信区间:0.21 - 1.44)、0.49(95%置信区间:0.11 - 2.08)、0.91(95%置信区间:0.42 - 1.98)和1.28(95%置信区间:0.51 - 3.20)。
在3.6年随访后,未发现德黑兰儿童和青少年的LCD与MetS及其组分的发病率之间存在关联。
