摘要

Purpose Nutrition Bio Shield (NBS) supplement is a natural product that is processed from whole wheat grains. This study aims to determine its effects on depression, anxiety, stress and food craving in women with depression and obesity in a double-blind randomized clinical trial. Design/methodology/approach Fifty-six eligible clients with body mass index >= 25 and mild or moderate depression signed the informed consent form. They were randomly assigned to receive daily 5 g of NBS or placebo. The assessments included the depression, anxiety and stress-21 questionnaire, food craving questionnaire, visual analogue scale for appetite, precise anthropometric measurements and body composition analyses. The assessments were conducted at the baseline and repeated after four and eight weeks. One month after the study completion, the participants' weight was assessed. The authors analyzed the data by independent sample t-test, repeated measures analysis of variance and multivariate analyses of covariance (MANCOVA). Findings At the baseline, no significant differences were observed between the groups regarding the main and demographic variables. After four weeks, stress reduced significantly in the NBS group (p = 0.04), and after eight weeks, anxiety (p = 0.02), stress (p = 0.008) and food craving (p = 0.05) reduced significantly in the NBS group compared with the placebo. After controlling for the demographic variables and baseline measurements, MANCOVA model revealed a significant effect of NBS in reducing anxiety (Eta-squared = 0.28; p = 0.001) and stress (Eta-squared = 0.19; p = 0.009). Fisher's exact test showed no significant difference regarding side effects between NBS and placebo (p = 0.47). Originality/value NBS supplement is a patent and natural product that is processed from whole wheat grains. This product was efficient in reducing stress and anxiety after controlling for demographic variables and baseline measurements compared with the placebo and was safe.
