Outcome Measures

Primary Outcomes (3)

  • Change in body mass index between baseline and week 15

    Change in body mass index (BMI) will be made through of the measure of body weight will be in kilograms (kg) to one decimal place, and the size in meters (m) to two decimal places. From these measurements the body mass index will be obtained using the formula: BMI = Weight (kg) / size (m)2.

    Baseline and week 15

  • Change in lipid profile (Total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides) between baseline and week 15

    Serum is measured from the same blood samples drawn for vitamin D levels. The processing and analysis of the samples will be done respectively through enzymatic technique, selective liquid detergent, selective detergent accelerator and Glycerol Phosphate Oxidase.

    Baseline and week 15

  • Change in 25-hydroxyvitamin D [25(OH)D] levels between baseline and week 15

    After a 10-12 hour fast, in peripheral venous blood 25-hydroxyvitamin D \[25(OH)D\] is quantified in serum by chemiluminescent microparticle immunoassay (CMIA).

    baseline and week 15

Secondary Outcomes (3)

  • Change in waist - hip ratio between baseline and week 15

    Baseline and week 15

  • Change of percentage body fat (PBF) in skin folds between baseline and week 15

    Baseline and week 15

  • Change in fasting blood glucose level between baseline and week 15

    Baseline and week 15

Study Arms (2)

Intervention group: 1000 IU DV

EXPERIMENTAL

The 75 participants assigned to the intervention group will take 1 DV capsule of 1000 IU daily for 15 weeks.

Dietary Supplement: 1000 IU D vitamin

Control group: 200 IU DV

PLACEBO COMPARATOR

The 75 participants of the control group will take 1 DV capsule of 200 IU daily for 15 weeks, this dose being the minimum recommended for children. The above, considering that it is ethical for the control group to receive a minimum dose of supplementation.

Dietary Supplement: 200 IU D vitamin

Interventions

1000 IU D vitaminDIETARY_SUPPLEMENT

Participants in the intervention group will receive 105 DV doses of 1000 IU. The supplementation will be given by the Farma de Colombia laboratory, known commercially as Farma D, whose presentation is in soft gelatin capsules. It is recommended to take one dose per day at the same time and participants should record the daily intake time of the supplement for 15 weeks on a calendar.

Also known as: Supplementation with 1000 IU vitamin D, Farma D 1000 IU
Intervention group: 1000 IU DV
200 IU D vitaminDIETARY_SUPPLEMENT

Participants in the control group will receive 105 DV doses of 200 IU. The supplementation will be given by the same laboratory; it will have the same characteristics and recommendations for the intake as for the intervention group.

Also known as: Supplementation with 200 IU vitamin D, Farma D 200 IU
Control group: 200 IU DV

Masking Details
The assignment of treatment in real time will be made with the support of a computer program. The procedure will take place by means of a single assignment sequence that determines the assignment code for each participant's treatment. This process allows all participants in the study to be assigned to any of the treatment groups. Supplements will be packaged in individual packages with the total number of doses per participant (105 doses). The coding of the packages will be in charge of the laboratory in charge of providing the supplements, which in turn will send to the designated person at the data center by institutional e-mail, a document with the list of codes and the dose of the supplement. The 1000 IU and 200 IU doses of VD will be provided in white containers and will be identical in terms of physical and organoleptic characteristics, to ensure that both participants and investigators are blinded to the treatment.

Intervention Model
PARALLEL
Model Details: Pilot study of a two-arm, triple-blind, parallel randomized controlled clinical trial, in 150 adolescents and young adults in the city of Bucaramanga-Colombia. All participants will be given 105 doses of VD. The 75 participants assigned to the intervention group will take one 1000 IU VD capsule daily for 15 weeks. On the other hand, the 75 participants in the control group will take 1 capsule of VD of 200 IU for the same time. The participants in both the intervention and the control group must record in a calendar the time of the daily intake of the supplement during the 15 weeks. The main outcomes are: serum levels of 25 (OH) D, body mass index and lipid profile; Secondary measures complement the previous ones (skin folds, waist-to-hip ratio). Other variables will be analyzed such as: assessment of dietary intake, physical activity, sun exposure, cigarette and tobacco consumption and adherence to supplementation with DV.
