Supporting American Indian/Alaska Native Mothers and Daughters in Reducing Gestational Diabetes Risk

2016-03-31 09:53:22 | BioPortfolio


The purpose of this study is to modify an existing Reproductive Health intervention for adolescents with diabetes for Gestational Diabetes and make it culturally appropriate American Indian/Alaska Native adolescents. The intervention will then be evaluated for effectiveness in AI/AN female teens at risk for GDM.


Gestational diabetes mellitus (GDM) has escalated to epidemic proportion and can cause maternal and child complications. GDM is a significant maternal risk factor for subsequent development of type 2 diabetes (T2D) and places the fetus at increased risk for congenital morbidity/mortality and for future onset of diabetes. American Indian and Alaska Native (AI/AN) women are twice as likely to develop GDM and T2D; mostly due to healthcare disparities (e.g., limited access to resources, lack of culturally relevant programs). The need for an inexpensive accessible GDM intervention in this population is compelling. The intervention should be delivered during adolescence and prior to sexual debut. Preconception counseling (PC) prevents unplanned pregnancies and significantly reduces risks of complications. If GDM in a previous pregnancy is an indicator of high risk in subsequent pregnancies, then preventing GDM in a first pregnancy is imperative. For a significant and innovative shift in paradigm, the Investigators propose a primary prevention PC intervention for AI/AN adolescent females at risk for GDM to enhance healthy lifestyle behaviors and family planning vigilance prior to this first pregnancy. The Investigators will target girls starting at the age of 12 to coincide with both the "Coming-of-Age" rituals for AI/AN girls during which many receive womanly advice from elder female family members, and the American Diabetes Association recommendation that PC in all females should start at puberty. This new directive will require support from the teens' mothers (or their female caregiver) and well-informed community health care professionals (HCP). Our objective is to adapt our current PC intervention (validated for teens with diabetes) using a sequential mixed-method design with a multi-tribal AI/AN community-based participatory research (CBPR) approach (e.g., Navajo, Cherokee, 40 Oklahoma tribes; 8 project members are AI/AN) by first using focus groups of teens, mothers, HCP, and Tribal leaders; and then testing this culturally appropriate PC theory-based intervention named Stopping GDM in AI/AN adolescent females 12 to <20yrs at risk for GDM (e.g., pre-diabetes or BMI> 85%). Teens and their mothers will receive the Stopping GDM to raise their awareness of the risks of GDM and benefits of healthy lifestyle to reduce these risks. By also providing mothers with PC knowledge and skills they can naturally weave cultural/social influences into their communications with their daughters. The multi-level intervention will be directed at the individual, familial and institutional levels simultaneously. AI/AN community-researcher partnerships have been established. A randomized controlled trial with a 15mos follow-up will test the effects of receiving online Stopping GDM on mother-daughter (M-D) cognitive/psychosocial and behavioral outcomes, and daughter family planning vigilance. The final online Stopping GDM program will be provided at no cost to the Indian Health Service (IHS) for dissemination to all their sites. HCPs at each clinical facility will be given free access to a continuing education program for PC training. This proposal provides a unique opportunity for a broad dissemination to significantly impact all IHS AI/AN female teens at risk for GDM, and help to prevent them and their future children from developing T2D.

Medical and Biotech [MESH] Definitions

Diabetes mellitus induced by PREGNANCY but resolved at the end of pregnancy. It does not include previously diagnosed diabetics who become pregnant (PREGNANCY IN DIABETICS). Gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to INSULIN RESISTANCE; GLUCOSE INTOLERANCE; and HYPERGLYCEMIA.

A condition of fetal overgrowth leading to a large-for-gestational-age FETUS. It is defined as BIRTH WEIGHT greater than 4,000 grams or above the 90th percentile for population and sex-specific growth curves. It is commonly seen in GESTATIONAL DIABETES; PROLONGED PREGNANCY; and pregnancies complicated by pre-existing diabetes mellitus.

The state of PREGNANCY in women with DIABETES MELLITUS. This does not include either symptomatic diabetes or GLUCOSE INTOLERANCE induced by pregnancy (DIABETES, GESTATIONAL) which resolves at the end of pregnancy.

A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.

Diabetes mellitus induced experimentally by administration of various diabetogenic agents or by PANCREATECTOMY.
