MOM Health

The MoM Health study ended recruitment in January 2019 and concluded in March of 2019. 

Pregnancy is a biologically relevant period during which cardiovascular risk factors may develop or worsen, contributing to future cardiovascular disease. Pregnant women also spend most of their day sedentary, which is defined as too much sitting as distinct from too little exercise. Sedentary behavior has emerged as a risk factor, independent from moderate-to-vigorous physical activity (e.g., exercise), for elevated blood pressure, obesity, diabetes, cardiovascular disease, and mortality in general populations, but there are no recommendations for sedentary behavior during pregnancy and few studies evaluate sedentary behavior across pregnancy.

To address these gaps, Monitoring Movement and Health (MoM Health) is a longitudinal cohort study of objectively measured sedentary behavior and physical activity across pregnancy in 120 young women. The study uses state-of-the-art sedentary behavior and activity assessment methodology, including 24-hour of assessment and posture using thigh-worn inclinometers and waist-worn accelerometers.  This study is funded by the American Heart Association (17GRNT3340016) and is currently in follow-up (not recruiting). We hypothesize that sedentary behavior will increase across pregnancy and that higher sedentary behavior will be related to worse cardiovascular health, specifically elevated blood pressure and excessive gestational weight gain.  Other exploratory outcomes include gestational diabetes, preeclampsia, gestational hypertension, and birth complications abstracted from medical records.  Lastly, with the long-term goal of identifying women at high risk of sedentary behavior during pregnancy and designing effective interventions, the study is also evaluating correlates and determinants of sedentary behavior which have never been studied during pregnancy.
