RESUMEN
BACKGROUND: Nursing is a profession that is associated with a lot of stress and a risk of being overweight or obese. The purpose of this research was to determine the comparative effectiveness of self-management (self-M) and group management (group-M) on nurses who were following a diet with the aim of proposing a proper planning and a healthy lifestyle for them. MATERIALS AND METHODS: This study was a simultaneous mixed-methods design (interventional and qualitative). The participants were all overweight or obese nurses working in teaching hospitals at Guilan University of Medical Sciences in 2019 (n = 96). In the qualitative part, data were extracted from semi-structured interviews. For quantitative data analysis, relevant statistical methods such as Kolmogorov-Smirnov test, analysis of variance (ANOVA), and analysis of covariance (ANCOVA) were used. For qualitative data analysis, the conventional content analysis approach was used and Lincoln and Guba's criteria were applied to ensure the accuracy of the data. RESULTS: In both quantitative and qualitative sections, the results showed that following a diet treatment with group-M is more effective than self-M. CONCLUSION: The results showed that a healthy lifestyle can be achieved for nurses if they participate in training classes and group programs, which are proven to be effective based on this article and some other studies. Also, since weight gain and obesity, as one of the most important problems of health systems, continue to increase and can impose a heavy economic and social burden on human societies, various general policies should be used and these solutions can range from home to society to prevent and control them.
RESUMEN
BACKGROUND/OBJECTIVE: In the current study, we aimed to explore the effects of rice bran oil (RBO) in adjunct to conventional medical therapy on left ventricular ejection fraction (LVEF), cardiometabolic risk factors, and inflammatory mediators in male patients with coronary artery disease (CAD). SUBJECTS/METHODS: The present randomized controlled trial included 40 men diagnosed with CAD (mean age = 55.76 years) who were randomly allocated into two groups to receive either 30 grams per day of RBO (intervention group) or sunflower oil (control group) plus a standard diet for eight weeks. At the initial visit, demographic and anthropometric data and blood samples were collected. LVEF levels and serum concentrations of lipid profile, glucose, uric acid, hs-CRP, and TNF-α were investigated. RESULTS: A total of 37 participants completed the study (n = 18 in the intervention group, n = 19 in the control group). Analysis of covariance (ANCOVA) adjusted for baseline values, age and body mass index revealed that RBO significantly improved LVEF (51.34%) and reduced triglyceride (125.01 mg dl-1), blood sugar (110.4 mg dl-1), total cholesterol (123.01 mg dl-1) and low density lipoprotein (56.88 mg dl-1) levels compared to sunflower oil ((45.56%), (155.93 mg dl-1), (128.94 mg dl-1), (163.93 mg dl-1) and (83.79 mg dl-1), respectively) following a 8-week trial (P-values < 0.05). Additionally, the test demonstrated that RBO consuming patients had significantly lower levels of serum uric acid (4.60 mg dl-1), TNF-α (6.99 ng L-1) and hs-CRP (2.11 mg L-1) compared to the control group ((5.92 mg dl-1), (15.23 ng L-1), (4.47 mg L-1), respectively) (P-value < 0.05). However, no significant changes were found regarding weight, blood pressure or serum HDL levels throughout the trial. CONCLUSION: Consumption of 30 grams per day RBO within a standard diet could be considered an effective non-pharmacological approach in improving LVEF, cardiometabolic risk factors, and inflammatory state in CAD. However, future trials are recommended for more clarification.
