The MAMAS Study is a research study being conducted by the University of California San Francisco (UCSF) and California Pacific Medical Center (CPMC). Carrying excess weight gain can increase the risk of health problems during pregnancy. The study is based on the idea that changes in diet and exercise may not be enough to help women manage their weight during pregnancy.

Women may need to learn additional skills to deal with stress and food cravings, manage difficult emotions, increase awareness of hunger and fullness, and encourage healthy eating and physical activity.

The MAMAS study is testing a stress reduction program based on the Mindful Motherhood Training and other mindfulness programs. The goal of the study is to learn if this program can help women achieve healthy weight gain during pregnancy and reduce stress.

Women ages 18-45, less than 16 weeks pregnant, and concerned about gaining too much weight may be eligible to participate.
