These estimates are from the first three Health eMoms birth cohorts (2018, 2019, and 2020 births). Weighted results are available from the first (Survey 1.1), second (Survey 1.2), third (Survey 2.1), fourth (Survey 2.2), and fifth (Survey 3.1) surveys of the Health eMoms program for the 2018 birth cohort, the three surveys for the 2019 birth cohort, and the first survey for the 2020 birth cohort. Mothers complete Survey 1.1 between three and six months postpartum, Survey 1.2 between 12 and 14 months postpartum, Survey 2.1 between 18 and 20 months postpartum, Survey 2.2 between 24 to 26 months postpartum, and Survey 3.1 between 30-32 months postpartum. The surveys include questions about:
- Maternal mental health.
- Social and community connection.
- Maternal leave.
- Employment and family-friendly practices in the workplace.
- Child care.
- Finance and resource insecurities.
- Health care access and interactions.
- Marijuana and other substance use.
- Oral health.
- And more!
Results are also available from the Health eMoms COVID-19 survey, which was distributed to all currently enrolled Health eMoms cohorts (2018-2020) between January 20th and February 3rd, 2021.

What is Health eMoms and how do these data fit into the bigger picture?
The Colorado Department of Public Health and Environment’s Health eMoms program is an online, longitudinal data collection system that draws a monthly sample of mothers from live birth certificates and recruits these mothers by mail to join an online survey platform. Enrolled mothers receive a total of six online surveys by email and text message from shortly after they give birth up until their child’s third birthday. The data we collect helps us understand the needs and experiences of Coloradan moms in order to develop and improve programs and policies that address these needs.
These data come from the first three of the six Health eMoms surveys. These estimates are cross-sectional (collected at one-point in time), but as we receive additional responses from the same mothers with the remaining four Health eMoms surveys, they can also serve as a basis for looking at individual-level trends in the topics bulleted above. If you have questions about how mothers’ experiences change over time, please see the “How do I request additional aggregate data from Health eMoms?” section below for information on how to submit a data request.
How is Health eMoms different from the Pregnancy Risk Assessment Monitoring System (PRAMS)?
Health eMoms and PRAMS are both maternal and child health data collection systems operated by CDPHE that use birth certificate records as the sampling frame for their monthly selection of mothers that they invite to participate in the system. Health eMoms and PRAMS work together to make sure that their samples are mutually exclusive. Both systems contact mothers by mail to complete surveys around three-four months postpartum but PRAMS is an extensive mail and telephone survey whereas Health eMoms is a series of brief web surveys. PRAMS collects data at only one point in time, but Health eMoms enrolls mothers in an ongoing survey program that continues up to their child’s third birthday.
Health eMoms asks some of the same questions as PRAMS on Survey 1.1, but the estimates that result may be slightly different due to differences in survey mode and weighting methodologies. Certain question types that are used in PRAMS, such as matrix questions, are not suitable for web surveys and are modified to work for Health eMoms. Web surveys also tend to be less subject to social desirability bias, which can result in higher estimates for behaviors perceived as negative. Difference in weighting methodologies may also result in small differences in point estimates. When comparing estimates across surveys, make sure to also compare confidence intervals to help assess whether there is a true difference.
How are the data weighted?
Health eMoms data are weighted by iterative proportional fitting, or raking, which balances the sample on key demographic variables to ensure that it is representative of the target population—all eligible births in Colorado. The 2018 and 2019 Birth Cohorts Survey 1.1, 1.2, 2.1 data were weighted on:
- Age. (Included starting with Survey 2.1)
- Race. (Included starting with Survey 1.2)
- Marital status.
- Medicaid status.
What is a confidence interval?
The confidence interval is the range of values that is likely to contain the true population parameter. When making statistical inferences about a population based on information collected from a probability sample, random error can affect estimates obtained from the sample. The confidence interval reflects the uncertainty around the estimate that results from random error.
How do I request additional aggregate data from Health eMoms?
Health eMoms will eventually be added to the CDPHE electronic data request system, but in the meantime, additional estimates or de-identified data sets can be requested directly from the Health eMoms Program Manager.
