Brief Summary:
This longitudinal design study is a continuation of the EDUGUTION project (Ref: PID2019-110063RA-I00; Clinical Trial: NCT05261373), a randomized controlled trial that was approved by the Clinical Research Ethics Committee of Cadiz (Registration No. 92.21; PEIBA No. 1026-N-21) in 2021. The aim of this study was to determine the benefits of three months of intervention with physical exercise and nutritional counseling on health in patients with type 2 diabetes.
Specifically, the aim of the present longitudinal study is to analyze the possible changes that may have occurred in the health and lifestyle habits of the subjects of the EDUGUTION project one year after the end of the study. The tests to be performed are the following: 1) Analysis of sociodemographic information, diet and habits and quality of life with previously validated questionnaires, 2) Fasting blood collection, 3) Anthropometric and body composition assessment, 4) Assessment of physical fitness: manual grip strength and maximal oxygen uptake test.
On the same day in the morning, participants will have to go to the University Hospital of Puerto Real and to the Exercise Physiology Laboratory of the Faculty of Education Sciences of the Puerto Real Campus of the University of Cadiz, one year after the end of the EDUGUTION study. Since there is no intervention, the duration of the study is a single day. In this study 120 patients will participate, the same patients who were included based on the inclusion and exclusion criteria and who completed the EDUGUTION study intervention one year earlier.

Detailed Description:
1. Sociodemographic Information and Questionnaires
Sociodemographic information will include gender, age, ethnicity, education, employment and position in the organizational hierarchy, household composition (and person responsible for food shopping and cooking), marital status and information on urban or rural place of residence. With respect to the questionnaires, the following will be included:
I) Adherence to the Mediterranean diet: the Mediterranean dietary pattern will be determined by a trained professional in a face-to-face interview. It will be established by means of a brief 14-item tool validated in Spanish population. Each question has a score of 0 or 1, since the values of the questionnaire range from 0 to 14. The higher the score, the greater the adherence to the Mediterranean dietary pattern.
II) Quality of life: Self-reported quality of life will be recorded by applying the Short Form 36-health survey (SF-36) questionnaire previously validated in Spain. The SF-36 is a generic measure of quality of life and has been evaluated for a wide variety of medical conditions, including diabetes. The SF-36 includes 36 questions assessing 8 subscales, scores for each scale range from 0 to 100, with higher scores indicating a higher level of function or well-being.
III) Bristol Scale: The Bristol visual stool chart will be used to classify stool form and condition, which classifies human stool form into seven groups, with 0 being the major constipation group and 7 being the major diarrhea group.
IV) Sleep quality: The Pittsburgh sleep quality index previously validated in Spain will be used. The r-MEQ (reduced Morningness-Eveningness Questionnaire) of circadian rhythms will also be used.
2. Blood collection
Participants will go to the University Hospital of Puerto Real coordinated by Dr. Florentino Carral in a fasting situation for the extraction of blood by venous blood for the measure of different blood parameters (biochemical parameters, glycosylated hemoglobin, hormones and exosomes). A clinical staff will take blood samples from a forearm vein after 8-10 hours of fasting. The sample will be collected in three Vacutainer plasma separator tubes anticoagulated with EDTA or heparin (5ml per tube) and one Vacutainer serum separator tube (10ml). Blood samples will be centrifuged for separation of plasma and serum, which will be stored at -80 °C until analysis. Plasma glucose and insulin concentrations will be determined by ELISA. These measurements will be used to calculate the HOMA-IR (Homeostatic Model Assessment for Insulin Resistance).
3. Anthropometry and body composition
Subsequently, participants will have to go to the exercise physiology laboratory at the UCA in Puerto Real on an empty stomach. First, anthropometry measurements (height and body circumferences) and body composition (weight, body fat, muscle mass and body fluids) will be taken using previously validated 8-electrode multifrequency bioimpedance (TANITA- MC780MA). Patients will wear short, light clothing and assume a specific posture according to the manufacturer's instructions. In addition, 24 hours before the measurement, the following considerations will be followed: (i) refrain from physical exercise, (ii) do not drink alcoholic beverages, (iii) do not drink energy drinks and (iv) fast for at least 8 hours. Participants should urinate just before the measurement to ensure the elimination of body fluids.
4. Physical fitness: Muscle strength and cardiorespiratory fitness.
Finally, two physical fitness measurements will be performed in the same laboratory. First, muscle strength will be assessed by a manual grip test with a TKK-5401 digital hand-held dynamometer. Cardiorespiratory fitness will be assessed by an incremental test to exhaustion on a cycloergometer using a Jaeger MasterScreen CPX® gas analyzer (CareFusion, San Diego, USA). The test will start with a load of 30W in women and 50W in men, increasing 20W every minute until reaching maximal exhaustion to know the VO2max (maximal oxygen uptake). A pedaling cadence of over 70 rpm should be maintained throughout the test. During the stress test, Dr. Jose Maria Martin Cano (collegiate number: 111108959) will control the heart rate and vital signs to prevent any risk in the test or if there is any emergency situation.
At the end of the measurements, a detailed report with the results of the study will be given to the participants.
