Recruiting now · Not applicable

Conditions studied: Diabetes During Pregnancy, Pregnancy Complications, Pregnancy in Diabetes, Gestational Diabetes Mellitus (GDM), Diabetes Complication, Gestational

In brief

The current study is a single-blind, parallel-group randomized controlled trial involving 108 participants with diabetes during pregnancy. The trial will compare leg ergometer with arm ergometer. Interventions will be delivered three times per week for eight weeks. The primary outcomes are glucose, exercise tolerance, weight, and psychological stress. Assessments will be conducted at baseline and after eight weeks. The trial will be carried out at Jinnah hospital, Services hospital, Sir Ganga Ram Hospital, Lahore. The hypothesis is that the leg ergometer including aerobic exercise will result in greater reduction in glucose and exercise tolerance, weight and stress management than arm ergometer.

Who can join

Age: 18 and older, up to 35. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Female participants aged 18-35 years.
• Gestational age 14-28 weeks (second trimester).
• Singleton pregnancy (confirmed by obstetric record) only to avoid complications of multiple gestation.
• Include both primigravida and multigravida (i.e., first or subsequent pregnancy).
• Women with first time GDM in pregnancy.
• Women with clinical diagnosis of gestational diabetes according to hospital/WHO criteria or hospital diagnostic test.
• Blood glucose levels:
• Random capillary glucose < 200 mg/dL at screening (to exclude overt diabetes)
• Blood pressure:
• Systolic BP < 140 mmHg and Diastolic BP < 90 mmHg (no confirmed gestational hypertension).
• If BP ≥140/90 mmHg, confirm with repeat measurement 4 hours apart; exclude if persistent.
• Willingness to participate and provide written informed consent.
• Medically cleared by obstetrician to participate in moderate aerobic exercise.

You may not qualify if…

• Previous Cesarean section or medically indicated bed rest.
• Known pre-existing diabetes mellitus (Type 1 or Type 2 prior to pregnancy).
• Known major obstetric complications (e.g., placenta previa, severe pre- eclampsia).
• Patients having multiple/twin/triplet pregnancies.
• Known major fetal anomaly.
• Anemic women with Hb < 9 g/dL (excluded to prevent exercise intolerance).
• Uncontrolled cardiovascular disease, musculoskeletal, or medical contraindications to exercise.
• Psychiatric conditions severe enough to hinder informed consent.
• Any other medical condition that, in the opinion of the obstetrician, makes participation unsafe.
