چکیده
زمینه و هدف: مواجهه با میدانهای الکترومغناطیسی (EMFs) بهدلیل اثرات بالقوه بر سلامت، مورد توجه قرار گرفته است. هدف این مطالعه بررسی تأثیر مواجهه با میدانهای مغناطیسی ایستا (SMFs) بر کیفیت خواب کارگران بود.
مواد و روش ها: در این مطالعه، ۱۸۵ نفر شرکت کردند. میزان مواجهه با میدان مغناطیسی با استفاده از دستگاه اندازهگیری و کیفیت خواب با پرسشنامه کیفیت خواب پیتسبورگ (PSQI) ارزیابی شد.
یافتهها: میانگین میدان مغناطیسی ایستا 22/65 میلیتسلا اندازهگیری شد. 46/48 درصد از شرکتکنندگان کیفیت خواب نامطلوب و 53/52 درصد کیفیت خواب مطلوب گزارش دادند. با افزایش هر یک سال سن، احتمال داشتن کیفیت خواب ضعیف 0/32 واحد و با افزایش هر ۱ میلیتسلا مواجهه با میدان مغناطیسی، احتمال کیفیت خواب ضعیف 0/16 واحد افزایش مییابد. یافتهها نشان میدهند که حتی مواجهه با میدانهای مغناطیسی در محدوده مجاز نیز ممکن است به کیفیت خواب ضعیف منجر شود و با افزایش مواجهه با میدان مغناطیسی، احتمال تجربه کیفیت خواب ضعیف نیز افزایش مییابد.
نتیجهگیری: گزارش خلاصه سیاستی حاضر به معرفی و پیشنهاد گزینه های سیاستی بهصورت اولویتهای کوتاهمدت، میانمدت و بلندمدت جهت مدیریت مواجهه با میدانهای مغناطیسی در محیطهای کاری پرداخته است. در اولویتهای کوتاهمدت بر آموزش و آگاهسازی کارگران و مدیران و همچنین پایش مستمر سطح میدان مغناطیسی تأکید شده است. در سطح میانمدت، توسعه پژوهشهای علمی درباره اثرات سلامتمحور این میدانها و تقویت اقدامات پیشگیرانه نظیر مشاوره و خودمراقبتی توصیه میشود. در بلندمدت، بر لزوم همکاری نهادهای دولتی و غیردولتی برای تدوین دستورالعملهای ایمنی و بهبود شرایط کاری تأکید شده است.

چکیده [English]
Background and Objective: Exposure to electromagnetic fields (EMFs) has attracted attention due to their potential health effects. The aim of this study was to examine the impact of exposure to static magnetic fields (SMFs) on workers’ sleep quality.
Method and Material: A total of 185 participants were included in the study. Magnetic field exposure was measured using a specialized device, and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).
Results: The average static magnetic field was 22.65 millitesla (mT). Among participants, 46.48% reported poor sleep quality, while 53.52% reported good sleep quality. Results indicated that with each additional year of age, the likelihood of poor sleep quality increased by 0.32 units, and with each 1 millitesla increase in magnetic field exposure, the likelihood of poor sleep quality increased by 0.16 units. These findings suggest that even exposure to magnetic fields within permissible limits may lead to poor sleep quality, and as magnetic field exposure increases, the probability of poor sleep quality also rises.
Conclution: This policy brief introduces and proposes policy options categorized into short-term, medium-term, and long-term priorities for managing occupational exposure to magnetic fields in the workplace. In the short term, emphasis is placed on educating and raising awareness among workers and managers, as well as continuous monitoring of magnetic field levels. At the medium-term level, expanding scientific research on the health effects of these fields and strengthening preventive measures such as consultation services and self-care practices are recommended. In the long term, collaboration between governmental and non-governmental organizations is emphasized to develop safety guidelines and improve working conditions.
