About this study

Official title: Effects of Caloric Restriction and Exercise on Body Weight, Cardiometabolic Risk Markers, Immune Function, and Intestinal Flora in College Students: a Randomized Controlled Trial

The purpose of this study is to estimate the effects of caloric restriction and exercise on body weight, cardiovascular metabolic markers, immune function, and intestinal flora among college students, as well as the underlying mechanisms.

Read the detailed description

In recent decades, carbohydrate-centered food pattern has brought worrying negative effects on human health, including increasing incidence of overweight, obesity, and cardiovascular diseases. Animal experiments based on rhesus monkey showed that caloric restriction could prolong their healthy life years, while reports from population-based studies are quite inconclusive. There are some studies reporting that caloric restriction did reduce the risk of cardiovascular disease in those with obesity, while some other cohort studies found that not eating breakfast might increase the risk of coronary heart disease, diabetes and other related diseases. In addition, a number of studies claimed that continuous caloric restriction is associated with the depletion of peripheral immune cells, immune suppression and reduced bone mineral density. In spite of those inconclusive results, on the whole, fasting and caloric restriction in some way do improve the conditions of metabolism, overweight and obesity. Previous studies mostly focused on middle-aged and elderly people, while recent studies in mice show that energy limitation in elderly people could not stop the aging process genetically or metabolically. Therefore, this study aims to estimate the effects of caloric restriction and exercise on body weight, cardiovascular metabolic markers, immune function, and intestinal flora among college students, as well as the underlying mechanisms. A pilot study containing around 40 participants will be conducted firstly to assess the feasibility of this intervention plan.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ExerciseBehavioural

    Rope-skipping exercise for three times a week (90 minutes each time, and there is a 10 min break after 20 min Rope skipping). Exercise bracelet and smart bracelet would be used to record the energy consumption throughout the study.

  • Caloric restrictionBehavioural

    1. In the first two weeks, participants would reduce their daily energy intake to 100% -110% of his or her basal metabolic energy under instruction, and stick to it till the end of the intervention.
    2. According to the dietary recommendation proposed by Chinese government, participants are required to take in cereals, vegetables, fruits, meat and eggs, while minimize the consumption of sugar-sweeten beverages.
    3. Participants are instructed to arrange their three meals according to the recommended energy distribution (3:4:3).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Body weight

    Body weight change of participants

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

Secondary outcomes (8)
  1. Body composition

    Skeletal muscle mass and fat mass were measured by body composition analyzers.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  2. Serum lipid levels

    Serum lipid levels (total cholesterol, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, triglycerides) were analyzed by the enzymatic method.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  3. Fasting plasma glucose

    Fasting plasma glucose were analyzed by the glucose oxidase method.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  4. Systolic and diastolic blood pressure

    Sitting systolic and diastolic blood pressure were measured with a validated mercury sphygmomanometer (model XJ1ID, China) and TZ-1 stethoscope.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  5. Immune inflammation indicators

    Immune and inflammatory indicators (ICAM-1, CCL2, VCAM-1, IL-6, IL-8, TNF-alpha, Leptin, Tau, BDNF, VEGF) were analyzed using the Luminex Human Magnetic Assay kit.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  6. Intestinal flora

    To measure the change of intestinal flora by analyzing feces genome 16S rDNA

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  7. Change in scores on Behaviour Rating Inventory of Executive Functioning-Adult Version (BRIEF-A)

    The executive functions were measured by the Behavior Rating Inventory of Executive Function-Adult Version (BRIEF-A) Self-Report Form. Items are rated 1 (never), 2 (sometimes), and 3 (often). There is no range for a total score. Raw scale scores are used to generate T-scores. A reduction in score indicates less impairment.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

  8. Circulating metabolome

    To measure the change of circulating metabolome by LC-MS/MS method.

    Measured: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention

Questions about this trial

What is this clinical trial studying?

A study testing Exercise and Caloric restriction in people with Cardiometabolic Risk and Weight Loss, run by Sun Yat-sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Body weight (time frame: Baseline (1-2 days before the intervention), right after intervention (8 weeks), 8 weeks after completion of the intervention). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
