Given these outcomes, several interventions have been developed to prevent repeated teenage pregnancy. Corcoran and
Pillai conducted a meta-analysis of secondary pregnancy prevention programs for teenage mothers, which included school-based programs, home visitations, training, and cash assistance programs. Their review of 16 studies revealed a 50% reduction in the odds of repeated pregnancy (RP) for at least 19 months after the first pregnancy. They also found that the
effects of the programs started to diminish after 31 months, which may still be considered beneficial as it went beyond the
24-month duration for optimal birth spacing.
