Abstract：
OBJECTIVE: The primary objective of this study was to determine whether Healthy Eating Index (HEI) and Alternative Healthy Eating Index (AHEI) scores were associated with incident metabolic syndrome.
METHODS: This study is a secondary analysis of data from the Jackson Heart Study. HEI and AHEI scores were divided into quintiles and Cox proportional hazards regression models were analysed for 1864 African American adults free from metabolic syndrome at Exam 1 to examine the incidence of metabolic syndrome by quintile of dietary quality score.
METHODS: Hinds, Madison and Rankin counties, Mississippi, USA.
METHODS: African American adults, ages 21-94 years, 60·9 % female.
RESULTS: Over a mean follow-up time of 6·7 years, we observed 932 incident cases of metabolic syndrome. After adjusting for multiple covariates, a higher HEI score at Exam 1 was not associated with the risk of incident metabolic syndrome, except when looking at the trend analysis for the subgroup of adults with two metabolic syndrome components at Exam 1 (P-trend = 0·03). A higher AHEI score at Exam 1 was associated with the risk of incident metabolic syndrome (hazard ratio for those in the highest quintile compared to the lowest: 0·80 (95 % CI: 0·65, 0·99), P-trend = 0·03).
CONCLUSIONS: These findings suggest that a dietary pattern that scores higher on the AHEI may help reduce the risk of metabolic syndrome, even for adults who already have two of the minimum of three components required for a diagnosis of metabolic syndrome.

摘要：
目的：本研究的主要目的是确定健康饮食指数（HEI）和替代健康饮食指数（AHEI）评分是否与代谢综合征相关。
方法：本研究是对杰克逊心脏研究数据的二次分析。HEI和AHEI得分分为五分位数，并在考试1中分析了1864名无代谢综合征的非洲裔美国成年人的Cox比例风险回归模型，以通过饮食质量得分的五分位数检查代谢综合征的发生率。
方法：Hinds，麦迪逊县和兰金县，密西西比州,美国。
方法：非洲裔美国成年人，年龄21-94岁,60·9%为女性。
结果：在6·7年的平均随访时间内，我们观察到932例代谢综合征。在调整多个协变量后，在检查1时，较高的HEI评分与代谢综合征的风险无关，除了在检查1时观察具有两种代谢综合征成分的成人亚组的趋势分析（P趋势=0·03）。在检查1时，较高的AHEI评分与发生代谢综合征的风险相关（与最低五分之一相比，最高五分之一的风险比：0·80（95％CI：0·65，0·99），P-趋势=0·03）。
结论：这些研究结果表明，AHEI评分较高的膳食模式可能有助于降低代谢综合征的风险，即使对于已经具有诊断代谢综合征所需的至少三种成分中的两种的成年人也是如此。
