Healthy eating is a crucial concept encompassing biochemical, physical, and psychosocial domains, and various nutritional indices and scales have been developed to assess the healthfulness of individuals' diets. This study aimed to evaluate the validity of the My Nutrition Index and examine its relationship with the Healthy Eating Index-2015 in the Turkish population.
This cross-sectional study included 498 participants aged 19-64 years. Demographic and anthropometric data were collected, and three-day food consumption records were obtained to calculate both the My Nutrition Index and the Healthy Eating Index-2015. Validity of the MNI was assessed by examining its correlation with the HEI-2015 using Pearson's correlation test. Additionally, subgroup analyses were conducted to explore associations between MNI scores and demographic variables. Data analysis was performed using the IBM SPSS Statistics 26 software package.
Of the 498 participants, 65.4% were female and 34.6% were male. The mean age of the participants was 32.59 ± 14.34 years, and the mean body mass index was 24.58 ± 5.03 kg/m². The mean score for the My Nutrition Index was 47.91 ± 15.88, while the mean score for the Healthy Eating Index was 56.87 ± 10.49. A significant positive correlation was observed between the total score of the My Nutrition Index, the electrolyte, vitamin, and mineral subscales, and the Healthy Eating Index-2015 (p < 0.05). The mineral index scores of women were lower than those of men, and the My Nutrition Index score of individuals classified as underweight was lower than those of individuals with normal weight and obesity. Smokers had lower scores on both the My Nutrition Index and the Healthy Eating Index-2015 compared to non-smokers (p < 0.05).
The My Nutrition Index demonstrated a significant correlation with the Healthy Eating Index-2015 in Türkiye. By providing a more culturally and contextually appropriate assessment tool, the My Nutrition Index may facilitate more targeted and effective interventions aimed at improving dietary habits. Future research should focus on validating the MNI in diverse populations and exploring its relationship with long-term health outcomes through longitudinal studies to further establish its clinical and public health relevance.
健康饮食是一个涵盖生物化学、身体和社会心理领域的关键概念，并且已经开发了各种营养指标和量表来评估个人饮食的健康程度。本研究旨在评估我的营养指数（My Nutrition Index）的有效性，并检验其与土耳其人群中2015年健康饮食指数（Healthy Eating Index-2015）的关系。
这项横断面研究纳入了498名年龄在19至64岁之间的参与者。收集了人口统计学和人体测量数据，并获取了三天的食物消费记录，以计算我的营养指数和2015年健康饮食指数。通过使用Pearson相关检验检查我的营养指数与2015年健康饮食指数的相关性来评估我的营养指数的有效性。此外，进行了亚组分析以探讨我的营养指数得分与人口统计学变量之间的关联。使用IBM SPSS Statistics 26软件包进行数据分析。
在498名参与者中，65.4%为女性，34.6%为男性。参与者的平均年龄为32.59±14.34岁，平均体重指数为24.58±5.03kg/m²。我的营养指数平均得分为47.91±15.88，而健康饮食指数平均得分为56.87±10.49。观察到我的营养指数总分、电解质、维生素和矿物质子量表与2015年健康饮食指数之间存在显著正相关（p<0.05）。女性的矿物质指数得分低于男性，体重分类为体重过轻的个体的我的营养指数得分低于体重正常和肥胖的个体。与非吸烟者相比，吸烟者的我的营养指数和2015年健康饮食指数得分均较低（p<0.05）。
在土耳其，我的营养指数与2015年健康饮食指数显示出显著相关性。通过提供一种在文化和背景上更合适的评估工具，我的营养指数可能有助于开展更有针对性和有效的干预措施，以改善饮食习惯。未来的研究应侧重于在不同人群中验证我的营养指数，并通过纵向研究探索其与长期健康结果的关系，以进一步确定其临床和公共卫生相关性。
