Background and purpose: Previous studies have shown conflicting results regarding to the relationship between shift work and lipid disorders. This study has investigated correlation between shift work and serum lipid.
Methods and Materials: An analytical cross sectional study was performed on a total of 2100 workers of Polyacryl Iran Company in 2013. The relationship between shift work, biochemical parameters, blood pressure and fasting blood sugar were investigated. SPSS (19) was used for data analysis. Comparisons of quantitative and qualitative variables were performed using, a one-way analysis variance (ANOVA) and Chi 2 tests respectively. The significance level defaults to 0.05.
Results: Total cholesterol average in 3-rotating shift workers (10/32 ± 50/171) was lower than total cholesterol average in the day-shift workers (19/34 ± 46/178) and 2-rotating shift workers (59/35 ± 15/178). ANOVA revealed a significant correlation between total cholesterol and shift work (p<0.001). The prevalence of total cholesterol ≥ 200 mg per dL was 25, 23.7 and 18.6% in day-shift, 2-rotating shift and 3-rotating shift workers respectively. Chi-square test showed that this is a significant difference (p<0.01).
Conclusion: This study was shown that total cholesterol and its prevalence was higher among 3-rotating shift workers than day workers and 2-rotating shift workers. So this study emphasizes on the importance of metabolic risk factors measurement among shift workers and prevent from this risk factors.

Background and Objectives: Lipid disorders, which are associated with the risk factors for cardiovascular diseases, are increasing in adolescents. Studies are indicative of the relationship of blood lipid level and chronic diseases with anthropometric indices in adolescents. This study aims to investigate lipid disorders and their relationship with anthropometric indices in adolescents. Materials and Methods: The sample of this descriptive and analytical study included 318 adolescents aged 10-18 who were selected and analyzed using stratified random sampling. The subjects’ demographic, anthropometric and biochemical data were obtained. The data were then analyzed using t-test, chi-square and ANOVA. Findings: Of the subjects, 19.5% had a total cholesterol above 170 mg/dl, 33.7% had a triglyceride level above 100 mg/dl, 12.6% had an LDL cholesterol level above 110 mg/dl, and 41% had an HDL cholesterol level below 40 mg/dl. The increase in BMI, waist circumference, waist to hip ratio, and waist to height ratio was accompanied by increased lipid disorders. Significance level was considered as 0.05. Conclusion: Although the use of anthropometric indicators alone cannot indicate the condition of the blood lipid profile in adolescents, but they can be used as a simple and accessible method.
