Experimental: Intervention
Women will receive the standard recommendation for engaging in 150 minutes of physical activity per week, ankle weights (2.5 pounds [1.1 kg]/ankle), instructions on ankle weight usage (wear during normal activity for 2 hours/day, 7 days/week).
The weight type and weight amount were chosen based on previously published literature and used in our preliminary work.

|---|---|---|
|
Weight loss
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Postpartum weight loss will be defined as weight change from initial weigh-in at NCH Visit 1 to final weigh-in at NCH Visit 2. Weight will be measured in person using the Tanita.

Body Fat %
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Percent body fat will be defined as the change in initial measurement at NCH Visit 1 to final measurement at NCH Visit 2. Percent body fat will be measured in person using the Tanita.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
BMI
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
BMI will be defined as the change from initial measurement at NCH Visit 1 to final measurement at NCH Visit 2. BMI will be measured using the Tanita for weight and obstetric medical record for height.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Waist-hip Ratio
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Waist circumference (cm) will be assessed at the middle point between the ribs and the iliac crest, with the participant standing.
Hip circumference (cm) will be measured at the widest circumference of the buttocks.
Change in circumference will be defined as the change from initial measurement at NCH Visit 1 to final measurement at NCH Visit 2. Waist-hip ratio will be measured in person using metric cloth tape.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: Oral Glucose Tolerance Test (OGTT)
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
A fasting 2-hour, 75g OGTT will be conducted during both NCH visits.
Glucose tolerance will be measured in mg/dL.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: HOMA
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
Insulin sensitivity (β-cell function) will be measured using the Matsuda index and HOMA-IR.
Matsuda index score and HOMA-IR will be determined based on insulin values (μU/mL) and glucose values (mg/dL) obtained from the OGTT.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: Hemoglobin A1c (HbA1c)
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
HbA1c will be analyzed as a percentage.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: Leptin
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
Fasting serum leptin will be measured in ng/mL.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|

Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: High sensitivity c-reactive protein (hs-CRP)
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
hsCRP will be measured in mg/L.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: Adiponectin
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
|
Blood will be collected during both visits at NCH and sent to the NCH lab for analysis.
Adiponectin will be measured in µg/mL.
|
NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)

|
Glycemia and Associated Biomarkers of Insulin Resistance and Metabolic Health: Lipid Panel
Prazo: NCH Visit 1 (25-35 days postpartum) to NCH Visit 2 (220-240 days postpartum)
