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.

Brief 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).
