Participants will receive nutritional education and daily high caloric oral nutritional supplements(experimental group),or will receive nutritional education and dietary instruction(control group).This study may provide data to support the development of clinical intervention strategies for malnourished Chinese children.', 'detailedDescription': "Background:Growth and development is an important indicator of children's health and nutritional status, and nutrition is the most important material basis for growth and development. The prevention and treatment of malnutrition in children can be achieved by choosing whole nutritional formulas for special medical purposes as oral nutritional supplements (ONS), which has been confirmed by some overseas clinical studies to promote the growth benefit of malnourished children, but no multicenter clinical study has been conducted in China on the effect of ONS on the improvement of growth and development of malnourished Chinese children.\n\nObjective and significance: To investigate the effects of high caloric ONS on body proportion, weight, linear growth pattern, neuropsychological development level and related health aspects (gut health, immune function, quality of life, etc.) in children, as well as to evaluate the safety of applying high caloric ONS, and to provide data to support the development of clinical intervention strategies for malnourished Chinese children.\n\nResearch design:A multicenter, randomized, controlled clinical trial design method is used to randomize children who meet the inclusion criteria into the experimental and control groups using a competitive entry method. The test group is given nutritional education and high caloric ONS (which can supplement 30% of the energy requirement), while the control group is given nutritional education and dietary instruction.Participants are followed up at 0, 1,2, 3, 6, and 12 months of enrollment. The investigators will collect dietary diaries, physical indicators, developmental quotient scores, quality of life measures, gut health, infectious disease-related questionnaires and safety indicators (blood biochemical indicators, urine routine) from children in both groups to comprehensively assess the effect of high caloric ONS intervention on physical growth, neuropsychological development levels and related aspects (gut health, immune function, quality of life, etc.) of malnourished children, as well as to conduct safety analyses.\n\nSample size:According to similar studies to date, a total of 200 people are recommended for this study.\n\nStatistical analysis: Statistical analysis is performed using SAS 9.4. For continuous variables (height, weight, BMI-Z score, DQ score, etc.), statistical descriptions are performed using mean and standard deviation (conforming to normal distribution) or median and interquartile range (IQR); for categorical variables, statistical descriptions are performed using frequency and percentage; for the main efficacy indicators, mixed-effects models are used for efficacy evaluation indicators according to the principle of adjusted intentionality analysis (mITT). For the safety evaluation, the number, frequency and incidence of adverse events and reactions are calculated, and the positive abnormal changes of laboratory biochemical indexes such as blood routine, urine routine, liver and kidney function are counted. p value \\< 0.05 is considered statistically significant.\n\nEthical matters and data protection: The guardians of the children participating in the study will sign an informed consent form. This study is approved by the local ethics committee. Patients' names will be abbreviated and study data will be assigned a code which will then be provided to the investigator. Parental authorization for patient health information will remain in effect until the study is completed.
