简要总结
This study aimed to evaluate the effects of Mediterranean diet education on sleep quality, physical activity levels, blood parameters, and anthropometric measurements among shift-working nurses.
Primary outcomes: Change in Mediterranean diet adherence and sleep quality scores from baseline to post-intervention.
Secondary outcomes: Changes in physical activity levels, anthropometric indices (e.g., BMI, waist-to-hip ratio), and blood parameters (fasting glucose, insulin, HOMA-IR, lipid profile).
详细描述
Background Shift work misaligns endogenous circadian rhythms with environmental light-dark cycles, predisposing workers to poor sleep, metabolic dysregulation, weight gain and cardiometabolic disease. Observational and experimental evidence indicates that dietary patterns rich in plant foods, monounsaturated fats and lean proteins-exemplified by the Mediterranean diet (MedDiet)-can attenuate inflammation, improve lipid and glycaemic profiles, and enhance subjective well-being. Educational interventions that reinforce MedDiet principles may therefore represent a pragmatic, low-risk strategy to mitigate health risks in shift-working nurses.
Study Desing Design: Single-group, pre-post intervention study Setting: Private general hospital in Muğla, Türkiye Sample Size: 130 nurses (≈80 % women) employed in rotating shifts, aged 18-55 y Allocation: Not applicable (no comparison arm)
Participant Eligibility Inclusion Criteria Registered nurse working ≥3 rotating shifts per month at the study hospital Age 18-55 years Written informed consent Exclusion Criteria Pregnancy or lactation Current participation in another lifestyle or drug trial Diagnosed sleep disorder requiring pharmacotherapy Medical condition necessitating therapeutic diet incompatible with MedDiet principles Inability to attend ≥75 % of education sessions
Intervention Mediterranean Diet Education Programme (Weeks 1-4) Format: Four weekly face-to-face group sessions (60 min each) delivered by a registered dietitian trained in behavioural counselling.

结局指标
主要结局
MEDAS Score
时间窗: Baseline (week 0) and post-intervention (week 8)
Change in Mediterranean Diet Adherence Score (MEDAS) Change in adherence to the Mediterranean diet as measured by the 14-item Mediterranean Diet Adherence Screener (MEDAS). This validated questionnaire assesses the frequency and quality of consumption of key Mediterranean dietary components. Scores range from 0 to 14, with higher scores indicating greater adherence.
