It is reported that an increase in food diversity would lower the risk of cardiac-cerebral vascular diseases.
A new index was introduced to develop a Chinese healthy food diversity (HFD) index, exploring the association with metabolic syndrome (MetS) and its components among Chinese adults. Two sets of data were used. The primary data were from a cross-sectional survey conducted in 2016 called the Chinese Urban Adults Diet and Health Study (CUADHS); the verification data were from the China Health and Nutrition Survey (CHNS) of 2009. The Chinese HFD index was developed according to the Chinese Dietary Guideline, with food consumption information from 24-h dietary recalls. The association between the index and MetS and its components was explored in logistic regression models.
Among 1520 participants in the CUADHS, the crude prevalence of MetS was 36.4%, which was 29.0% after the standardisation of age and gender by the 2010 Chinese national census. In the CUADHS, the HFD index ranged from 0.04 to 0.63. The value of the index among participants who are male, young, poorly educated, drinking or smoking, and with high energy intakes was significantly lower than that of their counterparts. In the verification dataset of the CHNS, there were 2398 participants, and the distribution of different genders and age groups was more balanced. The crude prevalence of MetS in the CHNS was 27.3% and the standardised prevalence was 19.5%. The Chinese HFD index ranged from 0.02 to 0.62. In the CUADHS, the Chinese HFD index was not significantly associated with MetS in covariate-adjusted models or with its components. In the CHNS, the Chinese HFD index had a significantly negative correlation with MetS and its components (i.e., elevated fasting glucose and elevated waist circumference) in covariate-adjusted models.
Increased food diversity may decrease the risk of MetS, which is important in dietary interventions of cardiac-cerebral vascular disease. This underscores the necessity of continued investigation into the role of HFD in the prevention of MetS and provides an integral framework for ongoing research.
据报道，食物多样性的增加会降低心脑血管疾病的风险。
引入一个新指标来制定中国健康食物多样性（HFD）指数，探讨其与中国成年人代谢综合征（MetS）及其组成成分之间的关联。使用了两组数据。原始数据来自2016年进行的一项横断面调查，即中国城市成年人饮食与健康研究（CUADHS）；验证数据来自2009年的中国健康与营养调查（CHNS）。中国HFD指数是根据中国膳食指南制定的，采用24小时膳食回顾的食物消费信息。在逻辑回归模型中探讨该指数与MetS及其组成成分之间的关联。
在CUADHS的1520名参与者中，MetS的粗患病率为36.4%，经2010年中国全国人口普查按年龄和性别标准化后为29.0%。在CUADHS中，HFD指数范围为0.04至0.63。男性、年轻、受教育程度低、饮酒或吸烟以及能量摄入高的参与者的指数值明显低于其对应人群。在CHNS的验证数据集中，有2398名参与者，不同性别和年龄组的分布更为均衡。CHNS中MetS的粗患病率为27.3%，标准化患病率为19.5%。中国HFD指数范围为0.02至0.62。在CUADHS中，在协变量调整模型中，中国HFD指数与MetS及其组成成分均无显著关联。在CHNS中，在协变量调整模型中，中国HFD指数与MetS及其组成成分（即空腹血糖升高和腰围增加）呈显著负相关。
食物多样性增加可能会降低患MetS的风险，这在心血管疾病的饮食干预中很重要。这强调了继续研究HFD在预防MetS中的作用的必要性，并为正在进行的研究提供了一个完整的框架。
