Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

A total of 1,180 women diagnosed with Gestational Diabetes Mellitus (GDM) from 2005 to 2009 and their children have and continues to be randomly assigned to either the intervention group or the control group. A total of 83 women with prior GDM and newly diagnosed diabetes at baseline survey have the nine-month lifestyle intervention program. GDM women in the intervention group will have five consulting sessions with a dietician during the first year and two sessions during the second year. The intervention group are given detailed advice about how to achieve the five goals of the intervention. The primary aim will test whether lifestyle intervention can reduce incident Type 2 Diabetes (T2D) in women with prior GDM. The second aim will test gene-intervention interactions through fine-mapping established genes for glucose, IR, lipids, obesity and T2D in relation to metabolic traits for T2D in GDM women. The third aim will evaluate the effects of the nine-month lifestyle intervention program on cardiovascular risk factors in women with prior GDM and newly diagnosed diabetes. The forth aim will assess if a lifestyle intervention targeting both GDM mothers and their offspring can greatly improve offspring's cardimetablic risk (body weight, glucose and lipid metabolism).

Study Groups

Lifestyle counseling

The women in the intervention group will be given detailed advice about how to achieve the six evidence-based goals of the intervention,7-9 including: 1) reduction in 5-10% of initial body weight in women with body mass index (BMI) ≥24 kg/m2 through the reduction of at least 10% of total calories of their normal meals, 2) total fat intake \<30% of energy consumed, 3) carbohydrate intake 55-65% of energy consumed, 4) fiber intake 20-30g per day, and 5) moderate or vigorous exercise for at least 30 min daily, seven days each week.

Group Type OTHER

Lifestyle intervention

Intervention Type BEHAVIORAL

The women in the intervention group will be given detailed advice about how to achieve the six evidence-based goals of the intervention,7-9 including: 1) reduction in 5-10% of initial body weight in women with body mass index (BMI) ≥24 kg/m2 through the reduction of at least 10% of total calories of their normal meals, 2) total fat intake \<30% of energy consumed, 3) carbohydrate intake 55-65% of energy consumed, 4) fiber intake 20-30g per day, and 5) moderate or vigorous exercise for at least 30 min daily, seven days each week.

\--------------------------------------------------------------------------------

Control

the subjects in the control group had been educated regarding general principles of healthy lifestyle that benefits T2D and obesity prevention, and also informed about the current evidence showing that the lifestyle intervention is effective in women at high risk for T2D during the "run-in" period.
