NCT02741037

Brief Summary

Mexican American women have significantly elevated rates of obesity and type 2 diabetes. The proposed study tests a novel intervention that capitalizes on an existing important family dyad (mothers and their adult daughters) to foster clinically significant and long-lasting health behavior change. If found to effective, this intervention strategy has great potential to address health disparities in this, and other, at-risk populations.

Study Arms (3)

Dyadic lifestyle intervention

EXPERIMENTAL

Mothers and daughters participate in the Unidas partner intervention together.

Behavioral: Dyadic lifestyle interventionOther: Usual Care

Individual lifestyle intervention

EXPERIMENTAL

Mothers participate in the Unidas intervention alone, without their related daughters. Unrelated daughters participate in the Unidas intervention alone without their related mothers.

Behavioral: Individual lifestyle interventionOther: Usual Care

Usual Care

OTHER

Mothers and daughters receive usual care.

Other: Usual Care

Interventions

Dyadic lifestyle intervention: The dyadic behavioral lifestyle intervention was modeled after the Diabetes Prevention Program (DPP), and was adapted to make it more easily accessible to low-income Latinas. In addition, this intervention arm has a dyadic component to examine the effectiveness of mothers and daughters engaging in the lifestyle intervention together as partners. Participants also will receive usual care.

Dyadic lifestyle intervention

Individual lifestyle intervention: The individual behavioral lifestyle intervention was modeled after the Diabetes Prevention Program, and was adapted to make it more easily accessible to low-income Latinas. Mothers participate in the Unidas intervention alone, without their related daughters. Unrelated daughters participate in the Unidas intervention alone without their related mothers. Participants also will receive usual care.
