FRIDAY, Oct. 7, 2022 (HealthDay News) — Regular texting targeting safer sexual behaviors in young adults does not reduce the incidence of chlamydia or gonorrhea at one year, according to a study published online Sept. 28. in The BMJ.

Caroline Free of the London School of Hygiene and Tropical Medicine and colleagues quantified the effects of a series of community-delivered text messages (safetxt) on the incidence of chlamydia and reinfected gonorrhea at one year in people aged 16 to 24. The analysis included 4,675 young adults randomly assigned to safetxt or control texts.

The researchers found that at one year, the cumulative incidence of chlamydia or gonorrhea reinfection was 22.2% in the safetxt arm versus 20.3% in the control arm (odds ratio, 1.13; range 95% confidence, 0.98 to 1.31). The number needed to harm was 64. The groups were similar in terms of the risk of motor vehicle crashes and domestic violence.
