RESUMO
INTRODUCTION: Cardiovascular disease is the main cause of disability and morbidity in many countries. Considering the significance of education in correcting unhealthy eating habits and improving nutritional behaviors that prevents cardiovascular diseases, the current study has been carried out to investigate the impacts of Beliefs, Attitude, Subjective Norms, Enabling Factors (BASNEF)-based educational program on the employees' nutritional behaviors. MATERIALS AND METHODS: This study was carried out on 120 randomly selected employees of Water and Wastewater Organization of Kermanshah. Individuals were divided into the control and intervention groups. Questionnaires devised based on BASNEF model and food frequency questionnaires were collected preintervention and 3-month postintervention. Educational program was performed in four training sessions. RESULTS: Significant differences between mean scores of knowledge and other items of BASNEF model as well as nutritional improvements were observed in the intervention group after 3 months (P < 0.01). CONCLUSION: BASNEF educational model positively affected nutritional behaviors of the employees to reducing cardiovascular risk factors.
RESUMO
BACKGROUND: There is some evidence that suggests a beneficial effect of calcium intake on serum lipid profile. The objective of this study was to determine the effect of 1000 mg calcium supplementation for 30 days on serum lipid profile in overweight or obese women. METHODS: A double-blind, randomized clinical trial was conducted in 44 overweight or obese adult women (body mass index (BMI) >or=25 kg m(-2), age: 25+/-6y) receiving 1000 mg elemental calcium daily (n=24) or placebo (n=20). Serum lipids, lipoproteins and apolipoproteins including triglyceride, total cholesterol, HDL cholesterol (HDLc), LDLc, VLDLc, ApoA-I and ApoB were obtained at baseline and after intervention. Dietary calcium and energy intake were estimated using 24 h dietary recall for 3 days. Statistical analyses were performed using SPSS software. RESULTS: No significant differences were observed in dietary, anthropometric and serum variables between groups at baseline. Although serum total, LDL cholesterol and triglycerides tended to increase in both groups, total cholesterol elevation was significant only in placebo group (P=0.01). Triglyceride and VLDLc increased significantly only in the calcium group (P=0.03). LDLc elevation was significant in both groups (P<0.05). HDLc decreased significantly in both groups (P<0.01). Apolipoproteins did not change significantly in any group. No significant differences were observed in serum variables between groups after intervention. CONCLUSIONS: No considerable beneficial effect due to short-term calcium supplementation in overweight or obese women's lipid profile was observed.
