About this study

This research study is to see if someone's ability to understand and use health information (health literacy) is linked to gaining a healthy amount of weight during pregnancy and having a baby with a healthy birth weight. The main question aims to answer if there is a positive correlation between increased health literacy, gestational weight gain, and adequate infant birth weight. We are conducting a prospective randomized trial involving 50 pregnant teenagers and their baby at a single institution. We will obtain study consent for 18 and 19 years old, and parental permission and assent for 13 -17 years old.

Control Group will complete the 20 questions health literacy during the first visit and after 8 weeks. Also, will complete the online called ASA 24 a 24-hour food recall tool. The ASA24 will be completed 2x /week for 8 weeks.

Intervention Group will complete the 20 questions health literacy during the first visit and after 8 weeks. Also, will complete the online called ASA 24 a 24-hour food recall tool. The ASA24 will be completed 2x /week for 8 weeks. In addition, participants assigned to the intervention group will be invited to participate in a private social media group. Participants will create a new account specifically for the study, or the study team can create an account on their behalf if they prefer. This will enable the study team to track participation without affecting any personal accounts. Education content will consist of published dietary recommendations during pregnancy, healthy craving hacks, healthy snacks, ways to get exercise in during the school day, etc. Participants will also be encouraged to ask questions and post any eating struggles.

Primary outcomes

  1. Health Literacy

    Time frame: All study participants will complete this survey at the beginning of the study and again after week 8.

    All data collected in the study design will be used to answer questions in this aim. The Maternal Health Literacy (MaHeLi) is a 20-item questionnaire used to assess health literacy in adolescents .

Secondary outcomes

  1. Demographic Information

    Time frame: From enrollment to the end of 8 weeks

    Demographic information will be collected, such as maternal age, gender, race, pre-pregnancy body mass index, weight, height, and BMI. Obstetrical and medical history will also be collected but not limited to gestational age, historical and current maternal outcome. Infant data will also be collected, such as gender, birth weight, infant unit admission, and infant outcome.

Other outcomes

  1. 24-hour food recall tool

    Time frame: The ASA24 will be completed 2x /week for 8 weeks.

    All study participants must complete the Automated Self-Administered 24-hour (ASA24) Dietary Assessment Tool to record dietary intakes. The ASA24 dietary assessment tool is a web-based tool designed for collecting detailed dietary intake information. ASA24 allows researchers and individuals to obtain dietary data through a 24-hour recall process, where participants report all the foods and beverages they consumed in the past 24 hours. ASA24 uses a large database of foods, providing nutritional information like calories, macronutrients, vitamins and minerals.
