Introduction: Regular physical activity can reduce the risk of developing diabetes in high risk populations including in women with gestational diabetes mellitus (GDM). This study applied the Health Action Process Approach (HAPA) to determine the motivational and volitional factors important in increasing physical activity among women with previous GDM.

Methods: Women with GDM receiving obstetric care at a teaching hospital in Sri Lanka were invited to participate in a survey 6–36 months post-delivery. At baseline and 8 weeks later, 152 women completed postal and telephone surveys that collected socio-cognitive and physical activity data. The study hypotheses were tested using structural equation modelling.

Results: The modified model fit the data well (CFI = .95, TLI = .94,RMSEA = .057) and explained 11% of the variance in behaviour. Action self-efficacy was the only important predictor of intention to be physically active. Intention as well as maintenance self-efficacy predicted planning, which, in turn, predicted physical activity. Planning mediated the effect of intention and self-efficacy (maintenance and recovery) on physical activity.

Conclusion: This study has identified predictors of physical activity among women with previous GDM that can inform intervention studies. Interventions targeting this population need to include planning strategies and enhance
