We examined pregnant women’s interest in using a website or mobile application to help them gain a
healthy amount of weight during pregnancy. Pregnant women (N=64) completed a short questionnaire
during routine prenatal care at hospital-based obstetric clinics in central Massachusetts during April–
August 2012. Eighty-six percent reported interest in using a website or mobile application to help them
gain a healthy amount of weight; interest ranged from 67% to 100% across demographics, clinical characteristics, and technology use. The Internet is a promising modality for delivering interventions to prevent
excessive gestational weight gain and associated maternal and child health consequences
