چکیده

مقدمه: عوامل مختلفی در رخداد تولد پیش از موعد از قبیل وزن‌گیری مادر حین حاملگی تأثیرگذار هستند. در این بین نقش وزن به دست آمده مادران در حین بارداری کمتر مورد بررسی قرار گرفته است. مطالعه حاضر با هدف بررسی ارتباط بین وزن قبل از بارداری، شاخص توده بدنی با سن حاملگی در زمان تولد انجام شد.
روش کار: در این مطالعه مقطعی که در تیر ماه سال 1394 در استان تهران انجام شد، تعداد 5170 زایمان مورد بررسی قرار گرفت که 77 مورد از آن‌ها به دلیل چند قلوزایی از مطالعه کنار گذاشته شدند و 5093 مورد، آنالیز شدند. اطلاعات مربوط به بارداری و زایمان زنان در 103 بیمارستان توسط 103 مامای آموزش دیده با استفاده از پرسشنامه طراحی شده جمع‌آوری شد. تجزیه و تحلیل داده‌ها با استفاده از نرم‌افزار Stata (نسخه 13) و روش‌های آمار توصیفی و روش رگرسیون ساده خطی انجام شد. میزان p کمتر از 05/0 معنی دار در نظر گرفته شد.
یافته‌ها: بر اساس روش رگرسیون چندگانه، وزن به‌دست آمده در طول بارداری ارتباط معنی‌داری با سن حاملگی در زمان زایمان داشت (001/0=p)؛ به طوری که به ازای یک واحد افزایش در وزن به دست آمده در طول بارداری، سن حاملگی در زمان تولد 052/0 هفته (95% حدود اطمینان: 068/0-036/0 هفته) افزایش (001/0=p) و احتمال تولد نوزاد زودرس کاهش می‌یافت. وزن (818/0=p)، قد (894/0=p) و شاخص توده بدنی (991/0=p) ارتباط معنی‌داری با سن حاملگی نداشتند.
نتیجه‌گیری: وزن‌گیری مناسب مادر در زمان بارداری از عوامل مؤثر در سن حاملگی در زمان تولد است؛ به طوری که وزن‌گیری مناسب منجر به کاهش تولد زودرس در زنان باردار می‌شود.

چکیده [English]

Introduction: Various factors such as maternal weight gain during pregnancy are important in the occurrence of preterm birth. Among these, the role of maternal weight gain during pregnancy is less studied. The present study was performed with aim to determine the relationship between maternal pre-pregnancy weight, body mass index and gestational age at birth.
MethodsIn this cross-sectional study which was conducted in Tehran in July 2015, a total of 5170 deliveries were examined of which 77 cases were twin pregnancy and excluded from the study and finally, 5093 were analyzed. The data related to pregnancy and delivery in 103 hospitals was collected by 103 trained midwives by using a designed questionnaire. Data analysis was performed by Stata software (version 13), and descriptive statistics methods and linear simple regression. PResults: Multiple linear regression analysis revealed that weight gain during pregnancy was significantly associated with gestational age at birth (P=0.001), so that for every one unit increase in weight gain during pregnancy, gestational age at birth increases 0.052 weeks (95% CI: 0.036-0.068 weeks) (P=0.001) and the chance of preterm labor decreases, but maternal weight (P=0.818), height (P=0.894) and body mass index (P=0.991) were not significantly associated with gestational age.
Conclusion: Weight gain during pregnancy is of the important factor in gestational age at birth, so that appropriate weight gain during pregnancy leads to reduced preterm birth in pregnant women.
