Early Nutritional Intake and Growth in Very Preterm or Very Low Birth Weight Infants: a Prospective Cohort Study

This study aims to explore the relation of early nutritional intake, especially oral nutrition intake, with growth and body composition among very preterm or very low birth weight infants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

As the survival of very preterm infants increases, it is important to evaluate their long-term outcomes. Nutritional intake during early life was important to the growth and development in infants, especially in preterm infants. Studies found that early nutrition exposure in preterm infants can effect scored of Griffith Mental Development Scales and body fat percentage at later life. Insulin-like growth factor-1, leptin, Ghrelin, C-Peptide are associated with fat mass in children. And accumulation of fat and insulin resistance (IR) in the early postnatal period are related to metabolism diseases in adulthood. However, previous studies on nutrition and growth or the body composition of preterm infants were mostly completed in developed countries, and no relevant data were available in China. Therefore, this study aims to establish a prospective cohort of very preterm infants to observe the effects of nutritional exposure in early life on growth and body composition in later life.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Z-scores of weight
Time Frame: at corrected age 40 gestational weeks
Computed according to the Fenton preterm growth standards (2013)
at corrected age 40 gestational weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure

Time Frame
Z-scores of length/height
Time Frame: at corrected age 40 gestational weeks
Computed according to the Fenton preterm growth standards (2013)
at corrected age 40 gestational weeks
Z-scores of head circumference
Time Frame: at corrected age 40 gestational weeks
Computed according to the Fenton preterm growth standards (2013)
