Brief Summary:
Pregnant African American women between 18 and 45 years of age will be enrolled at 20 weeks of gestation or less. Biological specimens (vaginal swabs, rectal swab) will be collected at enrollment, 23-24 weeks, at 28-29 weeks, and at the onset of labor. A urine sample will be obtained at entry and at the time of delivery for metabolomic analysis. Participants will also collect a dietary survey at entry, 23-24 weeks, and 28-29 weeks. The biological specimens will then be analyzed for their microbiomial profile. This will then be correlated with the timing of their delivery as well as other comorbidities such as obesity, hypertension, and diabetes.

Group/Cohort Intervention/treatment
Preterm Delivery
African american women who present for prenatal care who experience spontaneous preterm birth
Other: Survey, Sample collection
Survey is collected on the dietary intake of both cohorts. Sample collection is done from patients in both cohorts at multiple time points.

Term delivery
African american women who present for prenatal care who experience term birth
Other: Survey, Sample collection
Survey is collected on the dietary intake of both cohorts. Sample collection is done from patients in both cohorts at multiple time points.




Primary Outcome Measures :

  3. Medical comorbidities [ Time Frame: 36 weeks ]
    Evaluation of the comorbidities present in the cohort

  4. Gut Microbiome profile [ Time Frame: 36 weeks ]
    Evaluation of the characteristics of the gastrointestinal microbiome in cohorts

  5. Term delivery [ Time Frame: 36 weeks ]
    Delivery at term


Biospecimen Retention:   Samples Without DNA
Sample collection for bacterial microbiome identification and metabolic products
