Objective:Human resources are the most vital resource of any organizations which determine how other resources are used to accomplish organizational goals. This research aimed to identity factors affecting health workers’ motivation in Shahid Beheshti University of Medical Sciences (SBUMS).Method:This is a cross-sectional survey conducted with participation of 212 health workers of Tehran health centers in November and December 2011. The data collection tool was a researcher-developed questionnaire that included 17 motivating factors and 6 demotivating factors and 8 questions to assess the current status of some factors. Validity and reliability of the tool were confirmed. Data were analyzed with descriptive and analytical statistical tests.Results:The main motivating factors for health workers were good management, supervisors and managers’ support and good working relationship with colleagues. On the other hand, unfair treatment, poor management and lack of appreciation were the main demotivating factors. Furthermore, 47.2% of health workers believed that existing schemes for supervision were unhelpful in improving their performance.Conclusion:Strengthening management capacities in health services can increase job motivation and improve health workers’ performance. The findings suggests that special attention should be paid to some aspects such as management competencies, social support in the workplace, treating employees fairly and performance management practices, especially supervision and performance appraisal.

This information would be useful in planning and developing appropriate strategies to improve calcium intake in pregnant women. Efforts to increase calcium intake in pregnant women should focus on promoting nutrient-dense food and making these foods available and accessible, particularly to socioeconomically deprived women.

Background/aim: Gastrointestinal (GI) cancers are among the most common cancers in the world. Many risk factors may increase the chance of developing GI cancers. In recent years, a number of epidemiological studies have reported evidence of carcinogenic effects of opium in humans. This study aimed to investigate the relationship between opium use and GI cancer. Materials and methods: This case-control study was performed on 95 patients with GI cancer and 190 healthy individuals (matched for age, sex, place of residence, and smoking) in Rafsanjan, Iran, in 2018. Diet information, as well as history of smoking, the use of hookah, opium, and its derivatives was collected using a checklist in interview sessions. Conditional logistic regression was performed to investigate the proposed relationship and to estimate odds ratios (OR). Results: After adjusting the confounding variables, the use of opium was significantly associated with an increased risk of GI cancer development (OR = 5.95, 95% CI: 2.4-14.9). Also, a dose-response association was found between the cumulative use of opium and the risk of GI cancers. Consumption of fruit and vegetables reduced the risk of developing GI cancers in opium users (OR = 4.9 and 4.7, respectively). Conclusion: Opium, in the form used among drug users in this area, can lead to an increased risk of GI cancers. Fruit and vegetables have a protective and modifying effect on the risk of GI cancer development caused by opium consumption.

Background: One of the most important strategies to prevent diabetes as an important health issue in adolescents is education and awareness. The aim of this study was to determine the effect of educational intervention (EI) based on health belief model (HBM) on preventive behaviors of type 2 diabetes.Methods: The educational trial study was conducted in 2019-2020 among 143 high school male students at risk in Khash city (in southwestern Iran), using a random cluster method in two intervention and control groups. Data collection tools were demographic characteristics, knowledge, model constructs and disease prevention behaviors questionnaires. The training program was held in 7 one-hour sessions. Data were collected before, immediately and three months after the intervention and analyzed by SPSS 20 software using Chi-square, Independent t-test and Repeated Measures ANOVA at significant level of 0.05. Results: Immediately after the implementation of the training program in the intervention group, a significant increase was observed in the mean scores of knowledge, model constructs and behavior (P =0.0001). Three months after the EI, there was a significant difference between the mean scores of knowledge, perceived barriers, Cues to action and behavior between the two groups (p <0.05).Conclusion: Considering the effect of EI based on HBM on the promotion of diabetes prevention behaviors in students, the design, implementation and evaluation of theory-based EIs in the control and prevention of diabetes in adolescents is recommended.
