Maternal Carotenoids Across Pregnancy Study — MCAPS  

Pregnancy Related Clinical Trial

Official title: Effect of Pregnancy and Lactation on Carotenoid Status and Bioactivity

Status Active, not recruiting

Clinical Trial Summary

Before infants are born, they depend on their mother to provide the nutrients necessary to grow and develop, such as iron, folic acid, iodine and other vitamins and minerals. Pregnant people also rely on good nutrition to support their own health. In addition to essential nutrients, vitamins, and minerals, there are other natural components found in fruits and vegetables, called phytochemicals, that may support maternal and fetal health during pregnancy.

While more is known about the role of phytochemicals in adult health, surprisingly little is known about phytochemical nutrition during pregnancy. This study focuses on a group of phytochemicals, called carotenoids, during pregnancy.

The study will determine if and why levels of carotenoids in the body change across the course of pregnancy. Understanding carotenoid nutrition during pregnancy will improve the understanding ofnutrition needs of expectant mothers and their infants. To study these questions, both health pregnant and non-pregnant female adults will report on their dietary intake and participate in body measurements, health surveys, and carotenoid measurements of eyes, skin, and blood at time points corresponding with the first, second, and third trimesters of pregnancy as well as post-partum.

Clinical Trial Description

What a pregnant person eats is important for their own health and the health of their infant during pregnancy and after birth. Fruits and vegetables contain colorful substances called "carotenoids" which support the nutritional needs of the pregnant person and the infant, may fight inflammation, and may even benefit the person's memory and thinking ability. A person's carotenoid status can be measured with a blood sample and with optical measurements of the skin and eye. What isn't known, is if or why a pregnant person's carotenoid status changes over the course of pregnancy and the early post-partum period, and if those changes have consequences for pregnant person's and infant's health.

The goal of this study is to better understand how and why body levels of carotenoids, change during pregnancy and the post-partum period. We will study whether these changes can be explained by pregnancy, a person's diet, and changes in body composition. We will study if changes in a female's carotenoid status are associated with changes in memory or thinking ability, levels of inflammation, and her infant's carotenoid levels.

Ultimately, this information can guide nutrition advice for future pregnant people.

This study involves 5 study visits for the pregnant or non-pregnant adult female participants with an option to enroll infants for the final, post-partum, visit. For the four follow-up visits, adult participants will have body measurements, will complete surveys, and will provide a blood sample. At the final visit, lactating participants will be asked to provide a milk sample. If enrolled, infant participants will provide an optional blood sample, have body measurements, have an optical skin measurement, and their participating adult guardian will complete an infant eating survey. ;
