BACKGROUND
The association between anthropometric measures and dietary fat quality indices is unclear in pediatric age groups. The present study aimed to assess the association between dietary lipophilic index (LI) and thrombogenic index (TI) as dietary fat quality indices with anthropometric measurements in children and adolescents.
METHOD
This nationwide cross-sectional study was conducted on 4323 students aged 6-18 years that were selected by multistage cluster sampling from 31 provinces of Iran. Dietary intake was collected using a validated food frequency questionnaire and dietary LI and TI were calculated by formula. Data on anthropometric measures were collected by standard protocols.
RESULTS
The multivariate regression analysis revealed that TI and LI had inverse association with neck circumference Z-score (β = 0.11, p = 0.013 and β = 0.12 p = 0.006, respectively). There was a positive correlation between LI with height Z-score (β = 0.12, 95% CI: 0.01, p = 0.009). However, there was no significant association between LI and TI with other anthropometric indices (P > 0.05).
CONCLUSION
The quality of dietary fats was associated with some anthropometric indices. Further large-scale studies are required to highlight the importance of dietary fat quality indices in relation to cardio-metabolic risk factors in pediatric age groups. Reducing intake of saturated fatty acids, increasing consumption of monounsaturated fatty acids and a balanced intake of omega-3 and omega-6 to reduce the risk of cardiovascular diseases risk factors are recommended.
背景
在儿童年龄组中，人体测量指标与膳食脂肪质量指数之间的关联尚不清楚。本研究旨在评估作为膳食脂肪质量指数的膳食亲脂指数（LI）和血栓形成指数（TI）与儿童及青少年人体测量指标之间的关联。
方法
这项全国性横断面研究对4323名6至18岁的学生进行，这些学生通过多阶段整群抽样从伊朗31个省份中选取。使用经过验证的食物频率问卷收集膳食摄入量，并通过公式计算膳食LI和TI。人体测量指标的数据通过标准方案收集。
结果
多元回归分析显示，TI和LI与颈围Z评分呈负相关（β分别为0.11，p = 0.013和β为0.12，p = 0.006）。LI与身高Z评分呈正相关（β = 0.12，95%置信区间：0.01，p = 0.009）。然而，LI和TI与其他人体测量指标之间无显著关联（P > 0.05）。
结论
膳食脂肪质量与一些人体测量指标相关。需要进一步开展大规模研究，以突出膳食脂肪质量指数在儿童年龄组中与心血管代谢危险因素相关的重要性。建议减少饱和脂肪酸的摄入量，增加单不饱和脂肪酸的消耗量，并均衡摄入ω-3和ω-6以降低心血管疾病危险因素的风险。
