About

Our study aims to explore the influence of dietary chromium supplementation in the form of chromium picolinate, at different doses (200 µg and 400 µg per day), on the health of pregnant women with gestational diabetes. This study will also provide more information on the safety of this type of supplementation during pregnancies complicated by gestational diabetes mellitus.

The main questions it aims to answer are:

• Does chromium supplementation at various doses in women with gestational diabetes mellitus truly influence their glucido-lipidic metabolism, oxidative/antioxidant balance, and inflammatory state? If so, is it beneficial or detrimental?
• If this supplementation is beneficial, which dose is the most appropriate?
• Do these types of supplementation have any side effects on the health of the mother and fetus? The participants will take chromium supplements for 6 weeks (supplemented groups) while the control participants will not take them (healthy and diabetic control groups).

Chromium-supplemented participants will undergo a medical check-up every 02 weeks to closely monitor their health status and detect any potential side effects at an early stage.

Researchers will compare the biochemical profile, oxidative stress status, and inflammation markers between chromium-supplemented and non-supplemented participants to assess the impact of this trace element.

Researchers will compare the effects of chromium supplements at different doses with each other.

Inclusion criteria

• Healthy pregnant women:

  • Whose their gestational age is 28 weeks

  • They will be selected according to the criteria of the one-step method for screening for gestational diabetes mellitus established by the WHO.
  • They have no other pathology or complication associated with pregnancy.
  • They are subjected to insulin therapy and a low-calorie diet, rich in protein, fiber and beneficial lipids (they will all asked to keep their medical treatment prescribed by their doctor).

Exclusion criteria

• Pregnant women with unrecognized diabetes, type I or type II, will not be involved in this study.
• Pregnant women who were supplemented before one month or during pregnancy, or who will need other micronutrient supplements during the study to avoid their influence on the results.
• Pregnant women who develop other health complications will be removed from the study and replaced by others.
• Women with gestational diabetes mellitus who were unable to complete chromium supplementation up to 6 weeks will be excluded from the study and replaced by others.

No Intervention group

Description:

50 pregnant women with gestational diabetes who will not take any supplements will undergo two fasting blood draws. One during the 28th week of pregnancy and the other at the end of the 34th week, to assess biomarkers of glucose and lipid metabolism, oxidative stress, and inflammation.

Healthy pregnant women (Healthy control group)

No Intervention group

Description:

50 healthy pregnant women who will not take any supplements will undergo two fasting blood draws. one during the 28th week of pregnancy and the other at the end of the 34th week, to assess biomarkers of glucose and lipid metabolism, oxidative stress, and inflammation.
