BACKGROUND/OBJECTIVES: Recent studies have actively explored various factors associated with prediabetes, including physiological conditions, lifestyle, environmental factors, and dietary habits. This study aimed to analyze the association between relative grip strength (RGS), the Korean Healthy Eating Index (KHEI), and the prevalence of prediabetes in middle-aged adults aged 40 to 64 yrs.
SUBJECTS/METHODS: The study included 8,164 participants (3,240 men and 4,924 women) from the 2016-2019 Korea National Health and Nutrition Examination Survey who had not been diagnosed with type 2 diabetes. Participants were classified into a low RGS group and a high RGS group based on the median RGS value. We analyzed general characteristics, nutrient and food group intake, KHEI scores, and the prevalence of prediabetes according to RGS levels.
The results showed that individuals with higher RGS exhibited significantly lower body mass index, fasting blood glucose, and glycated hemoglobin levels. Furthermore, regarding diet quality, individuals with elevated RGS had significantly higher vegetable intake scores compared to those with lower RGS. In the age-adjusted analysis of prediabetes prevalence in relation to RGS and diet quality, women with lower RGS and lower diet quality scores had a significantly increased prevalence of prediabetes (adjusted odds ratio, 1.76; 95% confidence interval, 1.17-2.66).
These findings suggest that middle-aged women with low relative handgrip strength may need to implement active strategies to enhance their diet quality in order to prevent the progression to diabetes.
背景/目的：近期研究积极探索了与糖尿病前期相关的各种因素，包括生理状况、生活方式、环境因素和饮食习惯。本研究旨在分析相对握力（RGS）、韩国健康饮食指数（KHEI）与40至64岁中年成年人糖尿病前期患病率之间的关联。
对象/方法：该研究纳入了2016 - 2019年韩国国家健康与营养检查调查中的8164名参与者（3240名男性和4924名女性），这些参与者尚未被诊断出患有2型糖尿病。根据RGS中位数将参与者分为低RGS组和高RGS组。我们根据RGS水平分析了一般特征、营养素和食物组摄入量、KHEI得分以及糖尿病前期的患病率。
结果显示，RGS较高的个体体重指数、空腹血糖和糖化血红蛋白水平显著较低。此外，在饮食质量方面，RGS较高的个体与RGS较低的个体相比，蔬菜摄入量得分显著更高。在对糖尿病前期患病率与RGS和饮食质量进行年龄调整分析时，RGS较低且饮食质量得分较低的女性糖尿病前期患病率显著增加（调整后的优势比为1.76；95%置信区间为1.17 - 2.66）。
这些发现表明，相对握力较低的中年女性可能需要采取积极策略来提高饮食质量，以预防发展为糖尿病。
