Digital nudge: can text messages keep latinas active for the long haul?
NCT ID NCT03491592
First seen Aug 18, 2026 · Last updated Aug 19, 2026 · Updated 1 time
Summary
This study tests whether an enhanced web-based program can help inactive Latina women increase their physical activity and keep it up over time. The enhanced version adds text messages and personalized goal-setting to the original online intervention. Participants will be followed for 18 months to see how their activity levels change. The goal is to find a practical, culturally tailored way to promote lasting healthy habits.
