Meditation as Complementary Treatment for Chronic Hypertension in Pregnancy

March 8, 2022 updated by: University of Sao Paulo General Hospital

Use of Meditation as a Complementary Therapy in the Treatment of Gestational Hypertension

Pregnancy relates to arterial hypertension; it is an aggravating factor for pre-existing chronic arterial hypertension or a trigger for preeclampsia in normotensive women. The gestational hypertensive disease is managed conventionally with the pregnant woman's hospitalization and/or the use of antihypertensive medications. Nevertheless, this treatment may present some risks. The investigators seek to determine whether the intervention compared to the control can reduce the increase in blood pressure that pregnant women in the transition from the 2nd to the 3rd trimester.

Detailed Description

Primary research question:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
EXPERIMENTAL: Meditation group
Patients who are going to practice meditation and will receive only the usual outpatient care, with the aim of observing reduction of systemic blood pressure in this period.
Other: Meditation
Participants will be instructed to find a comfortable position, with a straight back, feeling the general state of their bodies (tensions, pains, heat, cold, etc.), to relax and pay attention to their own breathing, being aware of the air that gets into and out of the lungs. The women will be told that whenever their attention disperses (to another focus such as a thought, a sound, a body sensation, a judgment, etc.) they should go back to the original focus (breathing) with no feeling/judgment about the loss of focus. The practice involves focus and attention exercises and the gradual insertion of other anchors (focus points) as participants improve their skills in this practice.
Other: conventional treatment

Early prenatal care, when possible, is recommended as the first measure. Prenatal appointments usually take place fortnightly or weekly for hypertensive pregnant women. Extensive lab testing including specific tests for the first trimester, as well as tests for the diagnosis of superimposed pre-eclampsia and for the evaluation of lesions in target organs.

Drug treatment is only used when non-drug measures against hypertension are inefficient to decrease blood pressure levels and diastolic pressure is 90 mmHg or higher (in the first half of pregnancy) and over 100 mmHg (after 20 weeks).

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Comparison the means of diastolic blood pressure of pregnant women's between intervention group and control group.
Time Frame: 8 weeks

Diastolic blood pressure control in pregnant women with chronic hypertension between intervention group (meditation practice) and control group, in the transition from the second to the third trimester of pregnancy, when there is a physiologic increase in arterial pressure.

The diastolic pressure check will be in outpatient consultation with intervals of 15 days, during 8 weeks.

The device used for checking the pressure will be the GAMMA XXL LF of Heine General Medicine.

All blood pressure checks either in the intervention group or control group will be performed on the same device.
8 weeks
Comparison the means of systolic blood pressure of pregnant women's between intervention group and control group.
Time Frame: 8 weeks

Systolic blood pressure control in pregnant women with chronic hypertension between intervention group (meditation practice) and control group, in the transition from the second to the third trimester of pregnancy, when there is a physiologic increase in arterial pressure.

The systolic pressure check will be in outpatient consultation with intervals of 15 days, during.

The device used for checking the pressure will be the GAMMA XXL LF of Heine General Medicine.

All blood pressure checks either in the intervention group or control group will be performed on the same device.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment of quality of life with World Health Organization instrument for evaluating quality of life (Whoqol-bref) questionnaire.
Time Frame: 8 weeks

Checking potential increases or decreases in the quality life indicator during pregnancy using the Whoqol-Bref questionnaire as a result measure.

The questionnaire will be applied at the entrance of the participant in the study and at the end of the 8 weeks.

This questionnaire is composed of four domains of quality of life, totaling 24 questions.

The answers follow a Likert scale (from 1 to 5) and the domain scores for the WHOQOL-BREF were calculated by multiplying the mean of all items included within the domain by four. Potential scores for all domain scores, therefore, range from 4-20.

Only the total quality of life score will be considered in this study. For this study, a larger score on the Whoqol-Bref demonstrates a better outcome for the group performing the meditation intervention.
8 weeks
Assessment of anxiety and depression with The Hospital Anxiety and Depression Scale (HADS).
Time Frame: 8 weeks

Checking potential increase or decreases of anxiety and depression indicators during pregnancy using the HADS Scale as a result measure.

The questionnaire will be applied at the entrance of the participant in the study and at the end of the 8 weeks.

The Hospital Anxiety and Depression Scale (HADS) consist of 14 questions. It was divided into an Anxiety subscale (HADS-A) consist of 07 questions and a Depression subscale (HADS-D) consist of 07 questions both containing seven intermingled items.

Each items can be scored from zero (0) to three (3), composing a maximum score of 21 points for each sub-scale.

  • HAD-anxiety: no anxiety from 0 to 8, with anxiety ≥ 9;
  • HAD-depression: without depression from 0 to 8, with depression ≥ 9.

For this study, a larger score on the Resilience Scale demonstrates a worst outcome for the group performing the meditation intervention.
8 weeks
Assessment of the capacity to adapt and restore equilibrium to their lives and avoid the potentially deleterious effects of stress with Resilience Scale.
Time Frame: 8 weeks

Checking potential increase or decreases of the capacity to adapt and restore equilibrium to their lives and avoid the potentially deleterious effects of stress, during pregnancy using the Resilience Scale as a result measure.

The questionnaire will be applied at the entrance of the participant in the study and at the end of the 8 weeks.

The Resilience Scale is the scale that consist of 25 questions concerning the capacity to adapt and restore equilibrium to their lives to be rated on a 7-point scale

The Likert scale ranged from (1) disagree to (7) agree, with higher scores reflecting higher levels of trait mindfulness.

Possible scores range from 25 to 175 with higher scores reflecting higher resilience.

For this study, a larger score on the Resilience Scale demonstrates a better outcome for the group performing the meditation intervention.
8 weeks
Assessment on the presence or absence of attention to and awareness of what is occurring in the present, that differentiates meditation practitioners from others, with Mindful Attention Awareness Scale (MAAS)
Time Frame: 8 weeks

Checking potential increase or decreases on the presence or absence of attention to and awareness of what is occurring in the present, that differentiates meditation practitioners from others, during pregnancy using the MAAS as a result measure.

The questionnaire will be applied at the entrance of the participant in the study and at the end of the 8 weeks.

The Mindful Attention Awareness Scale is the unidimensional scale that consists of 15 questions concerning attention or awareness in routine situations to be rated on a 6-point scale on how frequently or infrequently the teste experiences those situations.

The Likert scale ranged from (1) almost always to (6) almost never, with higher scores reflecting higher levels of trait mindfulness.

The lowest possible value to be achieved when answering this scale is 15 and the highest possible value is 90.

For this study, a larger score on the MAAS scale demonstrates a better outcome for the group performing the meditation intervention.
