چکیده

مقدمه: زنان باردار و نوزادان در خطر کمبود ویتامین D قرار دارند که می­تواند باعث عوارض متعدد مادری و جنینی شود. مطالعه حاضر با هدف تعیین میانگین غلظت ویتامین D در زنان باردار و نوزادان ایران انجام شد.
روش‌کار: این مطالعه مروری بدون محدودیت زمانی تا مرداد 1395 بر اساس پروتکل مقالات مرور سیستماتیک و متاآنالیز (PRISMA) انجام شد. پایگاه‌های Magiran، Iranmedex، SID، Medlib، IranDoc، Scopus، PubMed، Science Direct، Cochrane، Web of Science، CINAHL و موتور جستجویGoogle Scholar توسط دو نفر از پژوهشگران به صورت مستقل با استفاده از کلیدواژه های MeSH جستجو شدند. میانگین اشتراکی با توجه به معنی­دار شدن شاخص I2بر اساس مدل اثرات تصادفی برآورد شد. آنالیز داده­ها با استفاده از نرم‌افزار متاآنالیز Review Manager version 5.3.5 انجام شد.
یافته‌ها: در 19 مطالعه، 4829 زن باردار و 1195 نوزاد بررسی شدند. میانگین سنی زنان باردار 31/0±01/27 سال به‌دست آمد. میانگین غلظت ویتامین D در زنان باردار ایران 02/15 نانوگرم بر میلی‌لیتر (CI 95%: 35/16-68/13) برآورد شد. این میزان در نوزادان در 6 مطالعه، 59/14 نانوگرم بر میلی‌لیتر (CI 95%: 23/19-94/9) برآورد گردید. تفاوت میانگین استاندارد شده غلظت ویتامین D در نان باردار در سه ماهه سوم و نوزادانشان از نظر آماری معنی­دار بود (001/0=p).
نتیجه‌گیری: میانگین غلظت ویتامین D در زنان باردار و نوزادان ایرانی بسیار پایین می­باشد و بین غلظت ویتامین D مادر در سه ماهه سوم و نوزاد ارتباط مستقیم وجود دارد، لذا پرداختن به مسئله کمبود ویتامین D در زنان باردار و نوزادان ایران باید به عنوان یک اولویت مهم بهداشتی در نظر گرفته شود.

چکیده [English]

Introduction: Pregnant women and newborns are at risk of vitamin D deficiency (VDD). VDD during pregnancy can lead to several maternal and fetal complications. This study was performed with aim to determine the mean concentration of 25-hydroxyvitamin D [25(OH)D] in pregnant women and newborns in Iran.
Methods: This meta-analysis study was performed without time limitation up to August 2016 based on the protocol of systematic review and meta-analysis studies (PRISMA). To access relevant studies, databases of Magiran, Iranmedex, SID, Medlib, IranDoc, Scopus, PubMed, Science Direct, Cochrane, Web of Science, CINAHL and Google Scholar were independently searched by two researchers. Search was performed using MeSH keywords. Pooled estimator was calculated according to significant I2 index based on the random effects model. Data were analyzed using Review Manager software version 5.3.5.
Results: Among 19 studies, 4,829 pregnant women and 1,195 newborns were enrolled. The mean age of pregnant women was 27.01±0.31 years. Mean concentration of vitamin D in pregnant women was 15.02 ng/ml (95% CI: 13.68-16.35). This rate in newborns of 6 studies was calculated 14.59 ng/ml (95% CI: 9.94-19.23). The standardized mean difference (SMD) of 25(OH)D concentration was significant in pregnant women at third-trimester and their newborns (P=0.001).
Conclusion: Mean concentration of vitamin D in pregnant women and newborns in Iran is very low and there is a direct relationship between maternal concentrations of vitamin D at third-trimester and newborn. Therefore, addressing VDD in Iranian pregnant women and newborns should be considered as a health priority.
