چکیده

مقدمه: افزایش بیش ‌از اندازه هورمون­ استرس در اواخر بارداری، مشکلات زیادی از جمله تغییر در فشارخون زن باردار را به همراه خواهد داشت. ابتلاء به افزایش بیش از اندازه فشارخون بارداری با خطراتی مانند عقب افتادن رشد جنین در داخل رحم، زایمان زودرس، جدا شدن جفت و مرده‌زایی همراه است. مطالعه حاضر با هدف بررسی تأثیر شش هفته تمرین پرانایاما در سه‌ ماهه سوم بارداری بر سطوح سرمی کورتیزول و سطوح فشارخون زنان باردار انجام شد.
روش‌کار: این مطالعه کارآزمایی بالینی تصادفی شده در سال 1395 بر روی 18 نفر از زنان سه‌ماهه سوم بارداری مراجعه‌کننده به یکی از مطب­های تخصصی زنان زایمان شهرستان بابل انجام شد. افراد به‌طور تصادفی به دو گروه پرانایاما (8 نفر) و کنترل (10 نفر) تقسیم شدند. گروه پرانایاما تمرینات آرام‌سازی و تنفسی را به‌مدت 6 هفته و به‌صورت 2 جلسه 60 دقیقه­ای در هفته انجام دادند. اندازه­گیری فشار­خون و نمونه­خونی به صورت ناشتا از ورید آرنجی در شرایط استراحت، 48 ساعت قبل و بعد از اجرای طرح انجام شد. تجزیه و تحلیل داده‌ها با استفاده از نرم‌افزار آماری SPSS (نسخه 23) و آزمون‌های شاپیروویک، تی مستقل و تی جفتی انجام شد. میزان p‌ کمتر از 05/0 معنی‌دار در نظر گرفته شد.
یافته­ها: بر اساس نتایج، تمرین پرانایاما باعث کاهش معنی‌دار سطوح سرمی کورتیزول گردید (035/0=p). همچنین سطوح فشارخون دیاستولیک در گروه تمرین نسبت به گروه کنترل کاهش معنی‌داری نشان داد (001/0=p). نتایج نشان داد که فشارخون سیستولیک در گروه تمرین نسبت به کنترل تغییر معنی‌داری نداشت (079/0=p).
نتیجه‌گیری: با توجه به اهمیت سه ماهه سوم بارداری، در صورت استرس بالای زنان باردار، جهت کنترل سطوح فشارخون و دیگر عوارض استرس می­توان از تمرینات پرانایاما بهره برد.

چکیده [English]

Introduction: The elevation of stress hormones at the end of pregnancy will cause many problems, including a change in blood pressure. The extreme enhancement of gestational hypertension is associated with dangers, such as intrauterine growth restriction, preterm birth, placental abruption, and stillbirth. The aim of this study was to evaluate the effect of six weeks of pranayama training during the third trimester of pregnancy on serum cortisol and blood pressure levels in pregnant women.
Methods: This randomized clinical trial was conducted on 18 women in the third trimester of pregnancy referring to a specialized gynecology clinic in Babol, Iran. The subjects were randomly divided into two groups of pranayama (n=8) and control (n=10). The pranayama group performed the relaxation and respiratory exercises for 6 weeks (two 60-minute sessions a week). Fasting blood pressure measurement and blood sampling (using median cubital vein) were performed in resting conditions 48 h before and after the implementation of the intervention. The data were analyzed in SPSS software (version 23) using Shapiro-Wilk test, as well as independent and paired sample t-tests. P-value less than 0.05 was considered significant.
Results: The results showed that pranayama training significantly decreased serum cortisol levels (P=0.035). Furthermore, diastolic blood pressure in the pranayama group showed a significant decrease, compared to that in the control group (P=0.001). However, there was no significant difference between pranayama training and control groups in terms of systolic blood pressure (P=0.079).
Conclusion: Given the importance of the third trimesters of pregnancy, pranayama exercises can be used to control blood pressure and other stress complications in case of high stress in pregnant women.
