An mHealth Intervention for Pregnancy Prevention for LGB Teens: An RCT.

ABSTRACT:

Background

Although lesbian, gay, bisexual and other sexual minority (LGB+) girls are more likely than heterosexual girls to be pregnant during adolescence, relevant pregnancy prevention programming is lacking.

Methods

A national randomized controlled trial was conducted with 948 14- to 18-year-old cisgender LGB+ girls assigned to either Girl2Girl or an attention-matched control group. Participants were recruited on social media between January 2017 and January 2018 and enrolled over the telephone. Between 5 and 10 text messages were sent daily for 7 weeks. Both experimental arms ended with a 1-week booster delivered 12 weeks subsequently.

Results

A total of 799 (84%) participants completed the intervention end survey. Participants were, on average, 16.1 years of age (SD: 1.2 years). Forty-three percent were minority race; 24% were Hispanic ethnicity. Fifteen percent lived in a rural area and 29% came from a low-income household. Girl2Girl was associated with significantly higher rates of condom-protected sex (adjusted odds ratio [aOR] = 1.48, P < .001), current use of birth control other than condoms (aOR = 1.60, P = .02), and intentions to use birth control among those not currently on birth control (aOR = 1.93, P = .001). Differences in pregnancy were clinically but not statistically significant (aOR = 0.43, P = .23). Abstinence (aOR = 0.82, P = .34), intentions to be abstinent (aOR = 0.95, P = .77), and intentions to use condoms (aOR = 1.09, P = .59) were similar by study arm.

Conclusions

Girl2Girl appears to be associated with increases in pregnancy preventive behaviors for LGB+ girls, at least in the short-term. Comprehensive text messaging-based interventions could be used more widely to promote adolescent sexual health behaviors across the United States.
