Methods: A cross-sectional comparative study was conducted in which ninety eight female nurses (55 day-time workers and 43 shift workers) from six educational hospitals of Jondi-Shapour University of medical sciences, Ahvaz, Iran were participated. A questionnaire including dietary, anthropometric, disease history and lifestyle pattern questions was completed and 3-day 24-hour recalls, Beck Depression Inventory (BDI) and Hospital Anxiety and Depression Scale (HADS) were collected. Serum hs-CRP and 25(OH)D3 concentrations were measured by immunoturbidimetric and electrochemiluminescent immunoassay method, respectively. Anthropometric indices were measured according to World health organization standard protocol. Independent sample t and chi-square tests were used for statistical analysis. Results: There was a lower dietary intake of thiamin, riboflavin, niacin, folate, magnesium and iron in shift worker compared with day-time nurses (p < 0.05). No significant differences in serum hs-CRP concentrations, serum 25(OH)D3 levels, vitamin D deficiency percentage, hemoglobin and hematocrite concentrations, and also anthropometric and psychiatric variables were found between two groups. Duration of exposure to sunlight was significantly higher in shift workers than in day time nurses. Engagement time in weekly physical exercise was around 11 times greater in day-time nurses compared with the shift work nurses (p = 0.001). Conclusions: This study showed that shift working is associated with some nutritional deficiencies and sedentary lifestyle among female nurses.展开更多

Participants consumed two cups of either pure FDS beverage(each cup containing 25 g freeze-dried strawberry powder equivalent to one serving of fresh strawberries; intervention group) or an iso-caloric drinkwith strawberry flavoring(similar to the FDS drink in fiber content and color; placebo group) daily for 6 wk. Anthropometric measurements, 3 d, 24 h dietary recall, and fasting blood samples were collected at baseline and at weeks 6 intervention. After lying down and relaxing for approximately 10 min, each participant's blood pressure was recorded in triplicate with 5 min intervals; recordings were made at baseline and the trial end-point. Each participant's lipid profile was assessed before and after intervention.RESULTS: Assessment at the weeks 6 intervention showed a significant reduction from baseline in total cholesterol levels and total cholesterol to high-density lipoprotein cholesterol(HDL-C) ratio in the intervention group(179.01 ± 31.86 to 165.9 ± 32.4 mg/L; P = 0.00 and 3.9 ± 0.88 to 3.6 ± 0.082 mg/L; P = 0.00 respectively), but the change was not significantly different between the two groups(P = 0.07, P = 0.29 respectively). Systolic blood pressure levels were significantly reduced from baseline in both the FDS and placebo drink groups(129.95 ± 14.9 to 114.3 ± 27.5 mm Hg; P = 0.02 and 127.6 ± 15.6 to 122.9 ± 14.47 mm Hg; P = 0.00 respectively), but the reduction was not significantly different between the two groups. Diastolic blood pressure was significantly reduced post-intervention in the FDS drink group compared to placebo group(78.7 ± 7.2 vs 84.4 ± 5.8; P = 0.01), the reduction was also significant within the FDS drink group(84.2 ± 8.03 to 78.7 ± 7.2; P = 0.00). Triglycerides, HDL-C concentrations and anthropometric indices showed no significant differences between or within groups. CONCLUSION: Short-term FDS supplementation improved selected cardiovascular risk factors in subjects with T2 D. Long-term effects on other metabolic biomarkers need to be investigated in future trials.展开更多
