Investigating the effect of MIND diet on physical fitness and anthropometric indices in female high school students: a cluster randomized controlled trial

The purpose of this study is to determine the effect of MIND diet on physical fitness and anthropometric factors among female high school students.

This study is a cluster randomized controlled trial

In this study, 6 eligible schools will be randomly assigned to one of the intervention and control arms and two types of MIND and control diets will be studied. people will be followed up for 3 months

Inclusion criteria: 1. High school girls aged 15 to 17 years 2. Informed consent of participants and their parents Exclusion criteria: 1) Cardiovascular diseases. 2) History of liver disease (alanine aminotransferase (ALT) and aspartate transaminase (AST) more than three times the normal values) and kidney disease (BUN and creatinine values higher than normal). 3) Suffering from cancer or a history of it. 4) suffering from a known cardiovascular disease (coronary artery disease, stroke, congestive heart disease) or a history of heart surgery. 5) having type 2 diabetes (fasting blood sugar above 126) or type 1 diabetes 6) receiving a special diet 7) having any underlying disease 8) people who do professional sports or are athletes 9 ) Allergy to any of the MIND diet components 10) Obese people (above 97th percentile)

The MIND diet is a combination of the Mediterranean diet and DASH, which will be adjusted according to the ratio of macronutrients: 50-60% carbohydrates, 25-30% fat, and 15-20% protein for the intervention group and the diet of the control group is similar to the typical Iranian diet with a combination of macronutrients. 50 - 60% carbohydrates, 25-30% fat and 15-20% protein

Weight, body mass index, waist circumference , body fat percentage, skeletal muscle percentage, cardiorespiratory fitness, anaerobic strength and Handgrip strength

Among the high school girls' schools in Yazd that are eligible to enter the study, 6 schools are randomly selected using SPSS software. 6 envelopes containing intervention or control codes prepared in advance are provided to the investigators. After opening each envelope, the investigators identify each school. In each school, according to the assigned group, 50 students are randomly selected (by generating 50 random numbers and choosing from the list of students of each school) and enter the study.

The general characteristics of the participants (without mentioning names and personal information) as well as the data for baseline and post-intervention values for primary and secondary outcomes will be made available to those interested after submitting the researchers' request and reviewing the principal investigators.

The data will be available to the researchers when the related articles are published.

The data will be available for all researchers interested in the subject.

Data will be available if the interested researcher(s) fills the proposal for a joint project and the sponsor of the study (Shahid Sadoughi University of Medical Sciences) confirms the protocol of the project.
