资源简介:
This dataset, includes data from 280 adults (18–65 years) with NAFLD, recruited from Gonabad University of Medical Sciences, Iran, in 2024. It examines dietary patterns, anthropometric indices, biochemical markers, and NAFLD severity to inform nutritional interventions for metabolic health.
Overview
Embedded in the article, the dataset comprises three tables with raw and adjusted data (corrected for age, sex, physical activity). Collected via standardized methods (questionnaires, 24-hour dietary recalls, clinical measurements, ultrasonography), it includes demographic, anthropometric, dietary, physical activity, biochemical, and NAFLD severity data, supporting diverse statistical analyses.
Tables
Table 1: Participant CharacteristicsFor 280 participants:
Demographic: Age (46.06 ± 12.37 years), sex (63.6% female), education (47.1% higher).
Anthropometric: BMI (29.19 ± 4.14 kg/m²), waist circumference (100.99 ± 9.24 cm).
Dietary: Energy intake (2899.61 ± 783.33 kcal) via three 24-hour recalls.
Physical Activity: Levels (63.2% low, 30.7% moderate, 6.1% high).
Biochemical: Triglycerides (186.32 ± 84.66 mg/dL), cholesterol (193.97 ± 37.65 mg/dL), LDL-C (113.74 ± 30.02 mg/dL), HDL-C (42.12 ± 11.68 mg/dL), glucose (95.35 ± 8.71 mg/dL), ALT (54.69 ± 32.35 U/L), AST (37.19 ± 19.06 U/L).
NAFLD Severity: Grades (24.6% grade 1, 63.2% grade 2, 12.2% grade 3).
Table 2: Food Groups and Factor LoadingsLists 23 food groups (e.g., vegetables, red meat) with factor loadings (>0.2) for healthy and unhealthy dietary patterns (KMO: 0.571; Bartlett’s: χ² = 1074.60, p < 0.001).
Table 3: Associations with Metabolic FactorsShows dietary pattern associations with BMI, HDL-C, cholesterol, and NAFLD grades via regression (e.g., healthy pattern: lower BMI, p=0.041; higher HDL-C, p=0.040; unhealthy pattern: higher cholesterol, p=0.007).
Data Collection
Participants had NAFLD, no chronic diseases, special diets, smoking, or alcohol use. Methods:
Demographic: Questionnaires.
Anthropometric: Seca scale, wall-mounted tape.
Dietary: 24-hour recalls.
Physical Activity: IPAQ-SF.
Biochemical: Blood analysis (Pars Azmoon kit).
NAFLD: Samsung RS80A ultrasonography.
Accessibility

Follows Declaration of Helsinki, with consent and approval (IR.TBZMED.REC.1402.750). Supported by Nutrition Research Center, Tabriz (ID: 73108).
***The dataset is also provided as an SPSS output file, facilitating direct statistical analysis for researchers using SPSS software.
本数据集纳入2024年于伊朗贡巴德医科大学(Gonabad University of Medical Sciences)招募的280名非酒精性脂肪性肝病(NAFLD)成年受试者(年龄18~65岁),旨在探究膳食模式、人体测量学指标、生化标志物与非酒精性脂肪性肝病严重程度,为代谢健康相关营养干预提供科学依据。
数据集概况
本数据集内嵌于研究论文,包含三张表格,涵盖原始数据与校正后数据(已针对年龄、性别、体力活动因素进行校正)。数据通过标准化流程采集,包括问卷调查、24小时膳食回顾、临床测量及超声检查,涵盖人口统计学、人体测量学、膳食摄入、体力活动、生化指标及非酒精性脂肪性肝病严重程度等多维度数据,可支持各类统计分析工作。
表格说明
表1:280名受试者的特征
1. 人口统计学特征:年龄(46.06±12.37岁)、性别(63.6%为女性)、受教育程度(47.1%拥有高等教育背景);
2. 人体测量学指标:体重指数(BMI)(29.19±4.14 kg/m²)、腰围(100.99±9.24 cm);
3. 膳食摄入:通过3次24小时膳食回顾采集的能量摄入量(2899.61±783.33 kcal);
4. 体力活动水平:63.2%为低水平,30.7%为中水平,6.1%为高水平;
5. 生化指标:甘油三酯(186.32±84.66 mg/dL)、总胆固醇(193.97±37.65 mg/dL)、低密度脂蛋白胆固醇(LDL-C)(113.74±30.02 mg/dL)、高密度脂蛋白胆固醇(HDL-C)(42.12±11.68 mg/dL)、血糖(95.35±8.71 mg/dL)、丙氨酸氨基转移酶(ALT)(54.69±32.35 U/L)、天冬氨酸氨基转移酶(AST)(37.19±19.06 U/L);

1. 人口统计学信息:通过问卷调查获取;
2. 人体测量学指标:采用赛康(Seca)体重秤、壁挂式卷尺完成测量;
3. 膳食摄入:通过24小时膳食回顾法采集;
4. 体力活动水平:采用国际体力活动问卷短卷(IPAQ-SF)进行评估;
5. 生化指标:血液样本检测采用帕兹阿兹蒙(Pars Azmoon)试剂盒完成;
6. 非酒精性脂肪性肝病严重程度:通过三星RS80A超声设备进行影像学评估。
