Brief Summary

Gestational diabetes mellitus(GDM) is a commom complication during pregnancy and associated with various adverse pregnancy outcomes for both the mother and her offspring. Imoportantly, with the gradual opening of a two-child policy, more and more Chinese women of reproductive age enter pregnancy have a history of GDM. Our previous study showed that regular exercise commenced in early pregnancy is effective in reducing the risk of developing GDM in Chinese overweight and obese pregant women. Thus, in this study, we want to evaluate the effect of lifestyle intervention with detailed information on how to eat and how to diet in preventing the recurrence of GDM.

Outcome Measures

Primary Outcomes (1)

  • GDM

    According to the new criteria amended in August 2014 in China, GDM was diagnosed when any one value reaches or exceeds 5.1 mmol/L at 0 hours, 10.0 mmol/L at 1 hour, or 8.5 mmol/L at 2 hours. Values of 7.0 mmol/L at 0 hours or 11.1 mmol/L at 2 hours were diagnosed as DM, regardless of the pregnancy stage

    24-28 gestational weeks

Secondary Outcomes (8)

  • birth weight

    up to 43 gestational weeks

  • gestational weeks

    up to 43 gestational weeks

  • delivery mode

    up to 43 gestational weeks

  • macrosomia

    up to 43 gestational weeks

  • LGA

    up to 43 gestational weeks

  • +3 more secondary outcomes

Study Arms (2)

lifestyle intervention group

EXPERIMENTAL

Pregnant women allocated to this group receive lifestyle intervention. With the dietary intervention we aimed to promote a healthy pattern of eating but not necessarily to restrict energy intake. With respect to advice on physical activity, we focused on incremental increases in walking from a pedometer assessed or encourage them to do moderate cycling.

Behavioral: lifestyle intervention with dietary and exercise recommendation

control group

NO INTERVENTION

Pregnant women allocated to this group receive standard prenatal care.

Interventions

With the dietary intervention we aimed to promote a healthy pattern of eating but not necessarily to restrict energy intake.For example we suggested exchanging carbohydrate-rich foods with a medium-to-high glycaemic index for those with a lower glycaemic index to reduce the glycaemic load, and restricting dietary intake of saturated fat. With respect to advice on physical activity, we focused on incremental increases in walking from a pedometer assessed, or encourage them to do moderate cycling during pregnancy.
