Evaluation of the effects of shift work on Mediterranean diet adherence, sleep quality, occupational stress and performance

Abstract

Shift work is becoming increasingly common worldwide. This research aims to evaluate the effects of shift work on Mediterranean diet adherence, sleep quality, body composition, occupational stress and performance. The study was conducted with 160 adult individuals working in institutions under the Burdur Provincial Directorate of Family and Social Services. Individuals' sleep quality was assessed using the Pittsburgh Sleep Quality Index, adherence to the Mediterranean Diet using the Short Questionnaire for Assessing Adherence to the Mediterranean Diet and Nutritional Sustainability, occupational stress using the Job Stress Scale, and occupational performance using the Individual Work Performance Scale. Anthropometric measurements included body mass index, waist circumference, waist-to-hip ratio, body fat percentage (BFP), and fat-free mass. Among the participants, 73.8% worked in shifts, 62.6% were classified as overweight or obese, and 93.7% had poor sleep quality. Additionally, 93.2% of individuals demonstrated low adherence to the Mediterranean diet. No significant difference in Mediterranean diet adherence was found between shift workers and non-shift workers (p>0.05). Individuals working in shifts had lower sleep quality, higher risk of metabolic diseases based on waist circumference and waist-to-hip ratio, and higher obesity rates (p<0.05). The decrease in sleep quality among shift workers was associated with increased occupational stress level and waist-to-hip ratio (p<0.05). Those with high occupational stress had higher levels of BFP and occupational performance. Decreased sleep quality in shift workers is associated with anthropometric measurements, occupational stress and performance. Furthermore, low adherence to the Mediterranean diet suggests that interventions to improve sleep and dietary quality may reduce cardiometabolic risk and occupational stress and improve performance.

Vardiyalı çalışmanın Akdeniz diyetine uyum, uyku kalitesi, iş stresi ve performansı üzerindeki etkilerinin değerlendirilmesi

Abstract

Bu araştırmanın amacı vardiyalı çalışmanın Akdeniz diyetine uyum, uyku kalitesi, vücut kompozisyonu, iş stresi ve performansı üzerine etkilerini değerlendirmektir. Araştırma Burdur Aile ve Sosyal Hizmetler İl Müdürlüğü kuruluşlarında çalışan 160 yetişkin birey ile yürütülmüştür. Bireylerin uyku kalitesi Pittsburgh Uyku Kalitesi İndeksi ile; Akdeniz diyetine uyumu Akdeniz Diyetine Uyum ve Sürdürülebilir Beslenmenin Değerlendirilmesi Kısa Anketi ile; iş stresi İş Stresi Ölçeği ile; iş performansı ise Bireysel İş Performansı Ölçeği kullanılarak değerlendirilmiştir. Antropometrik ölçümler olarak beden kitle indeksi, bel çevresi, bel/kalça oranı, vücut yağ yüzdesi (VYY) ve yağsız vücut kütlesi ele alınmıştır. Katılımcıların %73,8’i vardiyalı çalışmakta, %62,6’sı hafif şişman/obez olup %93,7’sinin uyku kalitesi kötüdür. Bireylerin %93,2’sinin Akdeniz diyetine uyumu düşük düzeyde olup vardiyalı çalışma durumuna göre uyumda anlamlı bir farklılık gözlenmemiştir (p>0,05). Vardiyalı çalışanların uyku kalitesi daha düşüktür; bel çevresi ile bel/kalça oranına göre metabolik hastalık riski ve obezite oranı daha yüksektir (p<0.05). Vardiyalı çalışanların uyku kalitesindeki azalma, iş stresi düzeyinde ve bel/kalça oranında artışla ilişkilidir (p<0.05). İş stresi yüksek olanların VYY ve iş performansı düzeyleri daha yüksektir. Vardiyalı çalışan bireylerin uyku kalitesindeki azalma antropometrik ölçümler, iş stresi ve iş performansı ile ilişkilidir. Bununla birlikte, Akdeniz diyetine uyumun düşük olması, uyku ve diyet kalitesini artıran müdahalelerin kardiyometabolik riski ve iş stresini azaltarak performansı artırabileceğini göstermektedir.
