Condition: Pregnancy; Weight Gain
MeSH terms: Body Weight; Weight Gain
Study type: Observational

Summary: 
      The primary purpose of this study is to assess the responses of pregnant women and their
      social network to six videos about health in pregnancy. Our goal is to assess a)
      acceptability and b) understanding of core messages about healthy eating, exercise and weight
      gain during pregnancy. We will also assess c) non-clinical sources of health information
      during pregnancy.
    

Detailed description: 
      Many women engage in suboptimal lifestyle behaviors during pregnancy. Many women do not
      realize that unhealthy diet, exercise and weight gain behaviors can be dangerous for their
      pregnancy and have harmful long-term consequences for their baby. There is great need for
      strategies to promote accurate knowledge about healthy behaviors during pregnancy. The
      purpose of this study is to assess responses to a brief (<1minute) video about healthy
      behaviors during pregnancy. The study sample will include pregnant women and members of their
      social network. Participants will be asked to watch a brief video and complete an anonymous
      online survey measuring their response to the video, and their basic demographics. The
      surveys will also assess how family and friends impact pregnant women's health behaviors.
      Online surveys are entirely anonymous. We will recruit pregnant participants from two
      sources: the University of Michigan Health System's prenatal clinics and a social media
      website (Facebook).

Study population: 
        Women recruited via either the social media, clinical, or online approach will be eligible
        for participation if they are aged 18 years and older, pregnant, and English-speaking.
        Women will be excluded if they deny being currently pregnant, do not identify as living in
        the US and aged 18 years or older, or if they report having previously participated in the
        study. The Qualtrics survey will automatically conclude if potential participants provide
        answers to screening questions that deem them ineligible. Participants will not be excluded
        based on racial-ethnic groups. Males will be excluded, as this is a study involving
        pregnant women.
