This report was a part of the National Food and Nutrition Surveillance Program, analyzing anthropometric statuses of children aged 24–60 m in Sistan and Baluchestan Province, Iran, as well as their associated demographic and socioeconomic determinants, 1401.

A total of 280 children aged 24–60 m were included in the study via multi-stage cluster random sampling proportional to cluster size method. Data on socioeconomic status of the household and demographic characteristics of the children were collected by health workers using face-to-face interviews with the mother/caregiver of the children. Necessary training to carry out anthropometric measurements was provided to the health workers through several workshops and webinars. Descriptive and analytical analyses were carried out using STATA v.17.0 (Stata, College Station TX, USA).

  The mean age of the studied children was 41.9 m ±0.6 with similar gender distribution (141 girls and 142 boys). Analyses showed that socioeconomic status was the most important determinant of stunting and underweight in children aged 24–60 m in Sistan and Baluchestan Province. Chances of being stunt and underweight in children, who were living in higher socioeconomic status, were respectively 60 and 80% lower than children whose families were in lower socioeconomic statuses.

Evidence indicate need of rapid intervention, including enhancement of access and purchasing power of the households living in the province and possibly  other deprived provinces of the country.

Bullying in nursing students is an important issue that can affect  self-esteem. People often use coping strategies in the face of negative situations. The aim of this study was to determine the relationship between bullying in the clinical setting and self-esteem and coping strategies used by nursing students.

This cross-sectional analytical study was performed in 2019 on 193 nursing students who were selected by stratified random sampling. Data collection tools were valid and reliable questionnaires of bullying behaviors in the clinical setting of Clarke et al., Rosenberg self-esteem, and Lazarus and Folkman coping strategies. Data were analyzed using SPSS at 95% confidence level and Pearson correlation coefficient and Independent t test.

The results showed that bullying in the clinical setting had no statistically significant relationship with self-esteem. Bullying in the clinical setting had a positive and significant relationship with emotion-based coping strategy in general (P=0.041) but had no statistically significant relationship with problem-based coping strategy.

Nursing students mostly use emotion-based coping strategies to deal with bullying, so effective coping strategies against bullying behaviors should be taught to nursing students.

The aim of this study was to investigate the effect of diet supplementation with bindii (Tribulus Terrestris), carob (Ceratonia siliqua) and ginger (Zingiber Officinale) on semen quality and fertility potential of rooster breeders. In this experiment, 30 roosters were assigned into 6 equal groups and fed the following diets during 30 days: 1) the base diet, 2) diet containing bindii, 3) diet containing carob, 4) diet containing ginger, 5) diet containing bindii and ginger, 6) diet containing bindii and carob. Semen samples were collected via abdominal massage once a week and the following parameters were evaluated: semen volume, number of spermatozoa, sperm motility, membrane integrity, morphology, viability and fertility potential. In result, diet supplementation with herbal additives in treatments received groups improved sperm quality and fertility potential compared to control group (P≤0.05). In conclusion, using herbal additives in rooster diet could be an effective method to improve rooster sperm quality and fertility potential.

The current study evaluated the effects of cryopreservation medium supplementation with folic acid as an antioxidant on post-thawed semen quality in bulk. Semen samples were collected from four proved Iranian Mahabadi bulls and diluted in extender containing 1.5% soybean lecithin. The diluted semen was assigned into six parts and supplemented with different doses of folic acid as follows: FA0 (extender without folic acid), FA0.05, FA0.1, FA0.2, FA0.4, and FA0.8 (extenders containing 0.05, 0.1, 0.2, 0.4, and 0.8 mM folic acid, respectively). Then, the semen samples were cryopreserved in liquid nitrogen. Sperm motility and velocity parameters, membrane integrity, abnormal morphology, viability, and lipid peroxidation were evaluated after thawing. In the results, FA0.05 presented higher (p≤0.05) total motility, progressive motility, membrane integrity, and viability and lower lipid peroxidation compared to other groups. Abnormal morphology was not affected (p>0.05) by treatments. In conclusion, supplementation of cryopreservation medium with 0.05 mM folic acid is a helpful method to conserve the quality of post-thawed semen in bulk.

High intakes of saturated and trans fatty acids can increase risks of cardiovascular diseases and cancers. Therefore, removal of partially-hydrogenated vegetable oils containing trans fatty acids has been suggested as one of the most effective health interventions. The aim of the current study was to investigate the policy effects of decreasing trans fatty acids in partially-hydrogenated vegetable oils as well as increasing intakes of unsaturated fatty acids through the introduction of novel products into the market and assessing the averages intake of saturated and trans fatty acids by households of capital cities in West Azerbaijan, Fars, Khuzestan, Lorestan, Semnan and South Khorasan Provinces.

This cross-sectional descriptive study was carried out on households in capitals of six provinces. Data were collected from the begging of May to the end of July 2014 using telephone interviews. Information on the types of fats and oils used for cooking as well as the purchase pattern and their quantities were collected using questionnaires. Fatty acid profiles of the consumed fats and oils were investigated as well.

The commonly consumed oils in the provinces included partially-hydrogenated vegetable oils, blended oils and frying oils. These oils included more than 70% of the total oil intakes. Furthermore, the average intakes of oils and fats per capita in the provinces were ordinarily West Azerbaijan, Khuzestan, Lorestan, South Khorasan and Fars. Intakes of trans fatty acids ranged from 0.32 in Fars to 0.67 g/person/day in West Azerbaijan. Results of this study showed that quantity of the trans fatty acids in partially-hydrogenated vegetable oils  has decreased by 95%, compared to that in previous decade. Moreover, consumption of partially-hydrogenated vegetable oils by households has decreased by 45%, compared to that in the last decade.

Effective policies, reformulations of oils and decreasing of trans fatty acids in partially-hydrogenated vegetable oils have included positive and effective changes, which have led to improve quality of fats and oils consumed by the households.

The aim of this study was improvement of ram frozen semen efficiency using addition of cysteamine antioxidant to freezing medium. In this experiment, semen samples were collected from five Zandi rams and add to the extender containing 0, 1, 2, 4 and 8 mM cysteamine. In sperm quality evaluation, sperm samples were evaluated and motion parameters, membrane integrity, morphology, acrosome integrity, mitochondria activity, viability and lipid peroxidation were assessed. The results showed using 2 mM cysteamine resulted in improving of sperm total and progressive motility, membrane integrity, mitochondria activity, acrosome integrity, and viability as well as reduction of apoptosis rate and lipid peroxidation. Using the treatment of 8 mM cysteamine caused to reduction of sperm quality after thawing and the antioxidant did not have any effect on sperm morphology. In conclusion, using 2 mM cysteamine in freezing extender could be a helpful strategy for improvement of ram sperm quality after cryopreservation.

Lifestyle and its various components have multiple effects on human health and disease. These include dietary intakes and nutritional patterns, which can greatly prevent non-communicable diseases by adhering to dietary recommendations and guidelines. One of the most important and practical studies, showing relationships between the diets and diseases and the level of health in each country, is the cohort design of the study that can show the trend of changes in incidence and exposure over time. Design of the Iranian teacherschr('39') cohort, which specifically investigates relationships between the food intake, nutritional status and physical activity and the incidence of non-communicable diseases, began in 2001. To design the study and compile the questionnaire, advices of Dr. Walter Wilt from Department of Epidemiology, Harvard School of Public Health, USA, were used. This study was carried out in collaboration with the Office of Community Nutrition Improvement, the Office of Health and Wellness of the Ministry of Education and the Center for Research on Social Determinants of Health, Iran. The choice of teachers was due to their ability to understand and answer questions. The self-administered questionnaire was developed based on the data from the Institutechr('39')s 2000–2002 national food consumption survey as well as statistical methods to investigate food items and their portion sizes. In a pilot study on 1000 teachers in Tehran, the feasibility of the study was verified. In general, follow up of outcomes in teachers includes fewer barriers due to their use of national insurance services.

In the recent decades, the Iranian Economy has been highly depended on Oil revenues. Considering the fact that a great part of non-oil exports are agricultures product, studying factors influencing growth of agricultural sector plays an important role in the Iran's economy. Supply domestic shocks and domestic demand pressure along with deviation of exchange rates from its equilibrium, have significant effects on the growth of agricultural sector. In this study, we examine the impact of supply and demand shocks on the economic growth, using the model of Blanchard and Quah and the method of Vector Auto Regression. The study data was obtained from the annual statistics during the years 1972-2007. The results revealed that the growth of agricultural sector is more sensitive to supply shocks than to demand shocks.
