چکیده


مقدمه: سندرم متابولیک تحت تأثیر عوامل متعددی پدید می‌آید و رفتارهای تغذیه‌ای، از عوامل مؤثر بر پیدایش آن می‌باشد. از این‌رو، هدف از این مطالعه آن بود که فواید و موانع درک شده را به عنوان دو سازه‌ی مؤثر بر ایجاد و حفظ رفتارهای تغذیه‌ای برای پیش‌بینی مصرف درشت مغذی‌ها در مبتلایان به سندرم متابولیک مورد ارزیابی قرار گیرد.

روش‌ها: در این مطالعه‌ی مقطعی، 329 نفر به صورت سیستماتیک از بین مراجعین مبتلا به سندرم متابولیک مراکز پنج‌گانه‌ی درمان صنعت نفت اصفهان در سال 1391 انتخاب شدند. داده‌ها توسط پرسش‌نامه محقق ساخته بر اساس سازه‌های الگوی ارتقای سلامت که طی مرحله‌ای جداگانه، طراحی و روایی و پایایی آن مورد بررسی قرار گرفته بود، در 11 بخش گردآوری گردید. برای تحلیل داده‌ها، از دو نرم‌افزار SPSS نسخه 16 و AMOS نسخه 16 استفاده شد.

یافته‌ها: در این مطالعه، به ترتیب همبستگی معکوس و مستقیم معنی‌داری بین فواید درک‌ شده و موانع درک ‌شده با دریافت درشت ‌مغذی‌ها مشاهده شد. مدل نهایی نشان داد که موانع درک ‌شده می‌تواند 72 درصد تغییرات انرژی دریافتی، 51 درصد تغییرات پروتئین، 42 درصد تغییرات کربوهیدرات و 88 درصد تغییرات چربی را پیش‌بینی کند و فواید درک ‌شده، می‌تواند 22 درصد تغییرات انرژی دریافتی، 18 درصد تغییرات پروتئین، 35 درصد تغییرات کربوهیدرات و 56 درصد تغییرات چربی را پیش‌بینی نماید.

نتیجه‌گیری: در این مطالعه موانع درک‌ شده قدرت پیش‌گویی‌کننده‌ی بیشتری نسبت به فواید درک ‌شده برای تعیین دریافت درشت‌ مغذی‌ها داشتند. بنابراین، با توجه به موانع متعدد درک ‌شده، نمی‌توان از این بیماران انتظار خود- مراقبتی تغذیه‌ای مطلوب را داشت.
