Validity of MNI and Its Relationship With HEI-2015

This study assessed the validity of the "My Nutrition Index" (MNI) and its relationship with the Healthy Eating Index-2015 (HEI-2015) in the Turkish population. A cross-sectional study of 498 participants aged 19-64 years was conducted, collecting demographic, anthropometric, and three-day food consumption data to calculate both indices. Pearson's correlation was used for analysis.

About this study

Introduction: 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.

Objective: This study aimed to evaluate the validity of the "My Nutrition Index" (MNI) and examine its relationship with the Healthy Eating Index-2015 (HEI-2015) in the Turkish population.

Methods: 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. Participants' nutritional data were analyzed, and the relationship between the two indices was examined using Pearson's correlation test. Data analysis was performed using the IBM SPSS Statistics 26 software package.

Treatment and study plan

Primary outcomes

  1. My Nutrition Index

    Time frame: Baseline

    The My Nutrition Index (MNI), developed by Busgang et al. (2022), evaluates 34 dietary components, including fats, proteins, carbohydrates, vitamins, minerals, and electrolytes. The index is calculated based on 3-day food consumption records, considering factors like height, weight, gender, age, activity level, and lifestyle factors such as alcohol, smoking, and caffeine intake. MNI consists of four sub-dimensions: Macronutrient, Electrolyte, Vitamin, and Mineral Index, with scores ranging from 0 to 100, reflecting diet quality. The validity of the index was compared to the Healthy Eating Index-2015 (HEI-2015).

  2. Healthy Eating Index-2015

    Time frame: Baseline

    The Healthy Eating Index (HEI) was updated in 2015 and consists of 9 adequacy components: Whole Fruits, Total Fruits, Greens and Beans, Total Vegetables, Dairy, Whole Grains, Fatty Acids, Total Protein Foods, and Seafood and Plant Proteins, as well as 4 moderation components: Sodium, Refined Grains, Added Sugars, and Saturated Fats, resulting in a total of 13 components. HEI-2015 was calculated using the data obtained from the 3-day food consumption records of individuals. The index yields a minimum score of 0 and a maximum score of 100, with higher scores indicating better diet quality. Diet quality is categorized as follows: >80 represents good diet quality, 51-80 represents a diet quality that needs improvement, and ≤50 represents poor diet quality.

Secondary outcomes

  1. International Physical Activity Questionnaire

    Time frame: Baseline

    In this study, the International Physical Activity Questionnaire Short Form (IPAQ) was utilized to determine the physical activity levels of the participants. The form, consisting of seven questions, provides information on sitting time, walking, moderately vigorous activities, and time spent in vigorous activities. The values obtained were evaluated according to the 'International Physical Activity Questionnaire Assessment Guide.' Based on this guideline, participants were classified into three categories: sedentary or less active, moderately active, and very active

  2. Sociodemographic characteristics

    Time frame: Baseline

    Sociodemographic characteristics will be assessed using a structured questionnaire developed by the researchers. The questionnaire will include items measuring age, gender, education level, and income status. The results will be presented as numbers and percentages for each characteristic.

  3. Body Mass Index (BMI)

    Time frame: Baseline

    Kilograms per square meter (kg/m2)

  4. Body weight

    Time frame: Baseline

    Body weight in kg

  5. Height

    Time frame: Baseline

    Height in cm
