It's unclear whether diet quality affects glycemic management. The index of nutritional quality (INQ) can examine diets both quantitatively and qualitatively (INQ). Hence, this study aimed to determine whether INQ and fasting blood sugar (FBS) are related among Iranian women.
This cross-sectional study was conducted on 360 adult Iranian women. Data were collected on the participants' general characteristics, medical history, anthropometric indices, physical activity, and dietary intake. For nutrient intake assessment, a valid food frequency questionnaire (FFQ) was used, and INQ was then calculated using the daily nutrient intake.
After adjusting for age, FBS was significantly inverse associated with INQ for vitamins A (B = -0.193, < 0.01), magnesium (B = -0.137, < 0.01), phosphor (B = -0.175, < 0.01), zinc (B = -0.113, < 0.01), vitamin K (B = -0.197, < 0.01), manganese (B = -0.111, < 0.01) and selenium (B = -0.123, < 0.01). The association between FBS and INQ for Se and Mn was disappeared after further adjustment for gender, body mass index (BMI), menopausal status, and total energy intake.
There was a significant inverse relationship between FBS and the INQ of vitamin A, manganese, phosphor, zinc, vitamin K, magnesium, and selenium. Prospective cohort studies should be conducted to establish a causal relationship between FBS and INQ.
饮食质量是否影响血糖管理尚不清楚。营养质量指数（INQ）可以从定量和定性两方面评估饮食。因此，本研究旨在确定伊朗女性的INQ与空腹血糖（FBS）之间是否存在关联。
本横断面研究对360名成年伊朗女性进行。收集了参与者的一般特征、病史、人体测量指标、身体活动和饮食摄入量等数据。采用有效的食物频率问卷（FFQ）评估营养摄入量，然后根据每日营养摄入量计算INQ。
在调整年龄后，FBS与维生素A的INQ呈显著负相关（B = -0.193，<0.01）、镁（B = -0.137，<0.01）、磷（B = -0.175，<0.01）、锌（B = -0.113，<0.01）、维生素K（B = -0.197，<0.01）、锰（B = -0.111，<0.01）和硒（B = -0.123，<0.01）。在进一步调整性别、体重指数（BMI）、绝经状态和总能量摄入后，FBS与硒和锰的INQ之间的关联消失。
FBS与维生素A、锰、磷、锌、维生素K、镁和硒的INQ之间存在显著负相关。应进行前瞻性队列研究以确定FBS与INQ之间的因果关系。
