简要总结
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.
详细描述
- 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.

结局指标
主要结局
Assessed changes in Plasma Insulin
时间窗: 1 year
The ELISA technique will be used to determine the concentration of plasma insulin (mU/L) in a fasting situation.
Assessed changes in Plasma Glucose
时间窗: 1 year
Plasma glucose (mg/dL) will be analysed in a fasting situation.
Assessed changes from Body composition: Fatmass and Fat-free mass
时间窗: 1 year
Body composition will be estimated using a multifrequency bioimpedance of 8 electrodes previously validated (TANITAMC780MA). The calculation of impedance can estimate the fat mass and fat-free mass in kilograms. The patients will wear light clothing and will assume a posture in accordance with the manufacturers' instructions. Other previous considerations will be followed 24 hours before the measure: (i) to refrain from vigorous exercise, (ii) to take alcoholic drinks, (iii) to take energy drinks, and (iv) to be in a fasting state for at least 8 hours.
Assessed changes in Muscle Strength
时间窗: 1 year
Muscle strength will be assessed by a manual grip test with a TKK-5401 digital hand-held dynamometer.
Assessed changes from cardiorespiratory fitness
时间窗: 1 year
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.
Assessed changes in Insulin Resistance
时间窗: 1 year
The Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) will be calculated using the glucose and insulin variables (HOMA-IR = fasting glucose (mg/dL) x fasting insulin (mU/L)/405).
Assessed changes in Glycosylated haemoglobin
时间窗: 1 year
Glycosylated haemoglobin (%) will be analysed in a fasting situation with the ADAMS™ A1C HA-8180V.
