Clinical Trial Summary

Based on the RE-AIM framework, this project intends to integrate the prevention and control measures of myopia and obesity, and establish a set of key suitable technical packages and guarantee systems for the "comorbidity-common-cause-common prevention" of myopia and obesity in children and adolescents. Dong cheng ,Tongzhou and Changping District in total selected 18 intervention schools and 18 control schools to apply the application, integrate the resources of the "family-school-community-medical institution", and establish a comprehensive combination of myopia and obesity in children and adolescents In the prevention and control demonstration area, intervention study was conducted to evaluate the comprehensive intervention effect of myopia and obesity in children and adolescents in the demonstration area, and to promote it through the regional monitoring system in Beijing. This project is the first time to establish a district-level comprehensive prevention and control demonstration area for children and adolescents with myopia and obesity that can be promoted, including key appropriate technology packages and promotion and application strategies. Healthy Beijing 2030" plan laid the foundation.


Description:

Baseline (March-April 2023), first follow-up (July-August 2023), and second follow-up (November-December 2023). The collection of data from study participants at baseline and third follow-up included questionnaire collection, anthropometric indicators, body composition measurements, vision measurements, blood pressure measurements, urine, saliva, and venous blood draws, as well as home questionnaires, school questionnaires, and interventionist physician questionnaires from the community hospitals and the project hospitals; and the first follow-up (the collection of data varied in each district, and was done according to the level of district cooperation) included questionnaire collection, anthropometric measurements, vision measurements, and blood pressure measurements, as well as home questionnaires, school questionnaires, and interventionist physician questionnaires from the community hospitals and the project hospitals. Myopia and activity records: including nighttime lighting, wake-sleep cycles, and movement. As well as family questionnaires, school questionnaires, community hospitals and project hospital intervention doctor questionnaires. All inspection items are operated by trained and qualified doctors and professional health technicians. The inspection will be arranged in the school, and the whole process is the same as the regular physical examination in the school. The child required 2 venous blood collections, urine and saliva collections during the year (at the initial stage and at the 3rd follow-up, respectively). Blood sample testing: 10ml of venous blood is drawn each time for blood routine and blood biochemistry. The blood process is safe. Blood samples include: blood biochemical indicators (fasting blood glucose (FBG), insulin, total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) ), dehydroepiandrosterone (DHEAS), adrenocorticotrophic hormone(ACTH) and so on). Hormone testing: Collect saliva samples in the morning and purchase ELISA kits to measure levels of thyroid hormones, estradiol and testosterone. Urine sample testing: use polypropylene urine cups and urine collection tubes (without PAEs plasticizers) to collect 10 mL of urine from the research subjects, and reserve the sample to collect the first excretion after getting up in the morning, before breakfast and before exercising. The collected urine samples were uniformly stored in a 5mL centrifuge tube and stored in a -20°C refrigerator. Urine PAEs and their metabolites: Ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was used to detect seven PAEs metabolites in students' urine: monomethyl phthalate (MMP), phthalic acid Monoethyl ester (MEP), mono-n-butyl phthalate (MBP), mono(2-ethylhexyl) phthalate (MEHP), mono(2-ethyl-5-phthalate) Hydroxyhexyl) ester (MEHHP), mono(2-ethyl-5-oxohexyl) phthalate (MEOHP). The content of the family and student questionnaires will include general conditions of children, general conditions of parents and families, as well as daily diet, physical activity and sleep. The name of the child will only be used for tracking and will be deleted after one year of observation to ensure that the information of the child and participants will not be leaked. All members of the project team have signed a confidentiality agreement, and all information in the questionnaire will not be leaked to the outside world.

Intervention

Other:
A cluster randomized trial of a comprehensive intervention nesting family and clinic into school centered implementation to reduce myopia and obesity among children and adolescents in Beijing, China
Myopia and obesity in children and adolescents have become serious public health problems that endanger public health, especially in China. Unhealthy lifestyle behaviors are environmental drivers of both myopia and obesity. This protocol describes a study to evaluate the effectiveness of "22510SS", that is 2 h of daytime outdoor activities ('2'); Limit screen time to no more than 2 h per day ('2'); Consume at least 5 servings of fruits and vegetables daily ('5'); Attain 1 h of physical activity daily ('1'); Consume 0 sugar-sweetened beverages ('0'); Reasonable sleep duration ('S'); Regular supervision ('S'). A school-based, multifaceted intervention strategy for myopia and obesity prevention, and to assess and explore the implementation of "22510SS" with regards to acceptability, feasibility, adoption, usage and maintenance.

Outcome

Type Measure Description Time frame Safety issue
Primary Myopia changes Refer to the "Guidelines for the Prevention and Control of Myopia in Children and Adolescents" issued by the National Health Commission in 2019 to check the vision of children. Approximate timing: Measured in the third and sixth month of intervention
Primary Height changes The record is in centimeters and accurate to one decimal place. Approximate timing: Measured in the third and sixth month of intervention
Primary Weight changes Use an electronic scale and check its accuracy and sensitivity before use. The accuracy error shall not exceed 0.1%, that is, the error per 100kg shall be less than 0.1kg. Approximate timing: Measured in the third and sixth month of intervention
Primary Waist circumference changes A tape ruler was used to measure horizontally around the midpoint of the line between the anterior superior iliac crest and the lower edge of the 12th rib (the thickest part of the waist was selected for obese patients); Approximate timing: Measured in the third and sixth month of intervention
Primary Hip circumference changes The subject stands naturally, with the arms drooping and moderately spread, the feet together, the legs are evenly weighted, the hips are relaxed, and the eyes are straight ahead. The tester places the tape on the most protruding part of the back of the buttocks, and circles the buttocks horizontally. During the test, the tape measure should be close to the skin, and the soft tissue should not be pressed. The reading should be taken when the subject exhales calmly. To ensure that the position of the tape ruler is correct, you can move the tape ruler up and down, compare the readings at different positions, and record the maximum value. Approximate timing: Measured in the third and sixth month of intervention
