Sexual minority women (SMW) in mid-age are at significantly higher risk for obesity, which is associated with greater vulnerability to cardiovascular disease, diabetes, cancer, and mortality. Further, this group also has elevated risk of early life adversities (ELA), such as childhood trauma and abuse. ELA has been linked to increased risks of midlife obesity and food addiction. However, interventions addressing this public health issue among SMW is scarce. Mindfulness-based interventions (MBI), delivered via smartphone, could be an effective approach to reduce the dual burden of obesity among ELA-affected SMW in their midlife. The study investigators developed an app-based MBI (28 daily modules, self-paced), "Eat Right Now" (ERN), which uses mindfulness to target craving-based eating. The current single-arm, exploratory clinical trial evaluates the utility of ERN among mid-aged sexual minority women who are overweight (BMI larger or equal to 25) and have a history of early life adversities. Specifically, two aims guide the study: (1) Investigators will examine the feasibility and acceptability of ERN among mid-aged sexual minority women who are overweight and have a history of early life adversities. Exit-interviews will be conducted to understand women's experience and inform future adaptation of the intervention. (2) Preliminary, pre-post trial efficacy will be evaluated. Participants will be screened using a two-part process taking place online, via an online screener and a Zoom-based screening. Research assessments will take place at baseline, post-intervention, and 4-month follow-up, digitally using using Qualtrics, LLC (Provo, UT, USA) survey management tool. Exit-interviews at post-intervention will be conducted via Zoom.
