Key finding
The incidence of diabetes after four years or more of follow-up was 9.0 and 15.3 cases per 1000 person-years in the lifestyle intervention and control groups, respectively.
A 4-year lifestyle intervention significantly reduced the incidence of diabetes among young women with a history of gestational diabetes compared to standard care.

Study focus
A 4-year lifestyle intervention significantly reduced the incidence of diabetes among young women with a history of gestational diabetes compared to standard care.
This study highlights the importance of lifestyle management in preventing diabetes among young women with a history of gestational diabetes. Given the rising incidence of type 2 diabetes, effective interventions like this could play a crucial role in public health strategies aimed at reducing diabetes risk in vulnerable populations.
The study's effectiveness data were unclear for some outcomes. Limited generalizability due to specific population characteristics. Potential biases in self-reported diabetes diagnoses.

The lifestyle intervention group had 9.0 cases of diabetes per 1000 person-years.
The control group had 15.3 cases of diabetes per 1000 person-years.
The intervention reduced diabetes incidence by 46% (95% CI: 10–67%).
Self-reported diabetes incidence was reduced by 40% (95% CI: 11–59%).
