Brief Summary

This study's aims are to examine the effects of yoga and aromatherapy on women's stress and immune function during pregnancy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This longitudinal, prospective, randomized controlled trial recruited 75 healthy pregnant women from a prenatal clinic in Taipei using convenience sampling. The participants were randomly assigned to the aromatherapy group (n=25), yoga group (n=25) or control (n=25) group using Clinstat block randomization.

The aromatherapy group received 70 minutes of aromatherapy massage once biweekly for 20 weeks; the yoga group participated in two weekly 70-minute yoga sessions led by a midwife certified as a yoga instructor for 20 weeks; the control group received only routine prenatal care. All participants' salivary cortisol and immunoglobulin A levels were collected before and after yoga or aromatherapy every 4 weeks from 16 to 36 weeks' gestation.

To collect a sufficient quantity of saliva, we used Salivette® cotton swabs (Salimetrics, State College, PA, USA), which were stored in double-layer plastic tubes with a lid. When participants chew a swab for about 2 to 3 minutes, saliva flow is stimulated to a sufficient amount (1 mL) for collection. After the tube was centrifuged at 1000 x g for 2 minutes, saliva was stored at -80°C until assay for salivary cortisol and IgA concentrations.

Cortisol was measured using a competitive enzyme-linked immunoassay (ELISA) kit (Cayman Chemical Company, USA), and salivary IgA was measured using double-antibody sandwich ELISA method per the manufacturer's instruction (ICL, Inc., USA).

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Aromatherapy massage

Ten aromatherapy group received 70 minutes of aromatherapy massage once biweekly by certified aromatherapy therapist for 20 weeks.

Group Type EXPERIMENTAL

Aromatherapy massage

Intervention Type BEHAVIORAL

All of the participants in the aromatherapy group underwent aromatherapy massage for 70 minutes every two weeks between 16 to 36 weeks GA (ten sessions total). The aromatic massage oils were composed of 2 c.c. lavender (Lavandula angustifolia) blended with 98 c.c. almond oil. This concentration of the mixed essential oil was kept at room temperature for massage use.

Yoga exercise

The yoga group participated in two weekly 70-minute yoga sessions led by a midwife certified as a yoga instructor for 20 weeks

Group Type EXPERIMENTAL

Yoga exercise

Intervention Type BEHAVIORAL

Prenatal yoga was offered in six 70-minute yoga sessions per week for 20 weeks, with 10-12 women in each session. Each participant should attend two sessions of yoga every two days, held in a quiet room near the prenatal clinic. Yoga specifically designed for women during the second and third trimesters, was guided by a midwife who was certified as a yoga instructor. Yoga included physical postures/ stretch, deep breathing, guided imagery, and deep relaxation. Before each posture/stretch, the instructor guided participants to relax each body part and calm their mind.

Control

the control group received only routine prenatal care.
