Peoples of Persian culture celebrate the last Wednesday of the year on its eve, the Tuesday night, according to the Persian calendar. Named Chaharshanbe-Soori, literally 'red Wednesday', the festivity is held on a day from 12 to 19 of March. The event precedes Nowruz (the Persian New Year) and comprises several traditions of which setting up bonfires and jumping over them is an integral part. Red refers to fire, itself symbolizing brightness, purity, life, and health in ancient Persia.1 The origin of the festivity goes back to a Zoroastrian tradition circa 1725 BC.

General population surveys often report that only a small proportion of individuals with common mental disorders seek mental health treatment, suggesting a high level of unmet need for mental health care in the community. In recent years, however, the number of adults in industrialized countries who are treated with antidepressant medications has dramatically increased. This paper reviews the public health impact of the increase in the use of antidepressant medications. Whereas some studies suggest a decrease in the incidence of suicide corresponding with the increase in the use of antidepressant medications, other studies do not report such an association. Furthermore, there has been no change in the period prevalence of common mental disorders concurrent with the increase in the use of antidepressant medications. Focusing effort and resources on expanding the capacity of mental health services and improving access to these services without attention to quality, intensity and appropriate targeting of treatments may have limited impact on the mental health of populations.

Introduction: Childhood obesity is a major public health crisis nationally and internationally. The prevalence of childhood obesity has increased over few years. It is caused by imbalance between calorie intake and calories utilized. One or more factors (genetic, behavioral, and environmental) cause obesity in children. Physical, psychological, and social health problems are caused due to childhood obesity. Hence, effective intervention strategies are being used to prevent and control obesity in children. The purpose of this manuscript is to address various factors influencing childhood obesity, a variety of interventions and governmental actions addressing obesity and the challenges ahead for managing this epidemic.Methods: In order to collect materials for this review a detailed search of CINAHL, MEDLINE, ERIC, Academic Search Premier databases was carried out for the time period 1999-2011.Results: Some of the interventions used were family based, school based, community based, play based, and hospital based. The effective school-based interventions were seen targeting physical activity along with healthy diet education. The major challenges faced by these intervention programs are financial, along with stigmatization of obese children. Governments along with other health care organizations are taking effective actions like policy changing and environmentally safe interventions for children to improve physical activity.Conclusions: In conclusion, childhood obesity can be tackled at the population level by education, prevention and sustainable interventions related to healthy nutrition practices and physical activity promotion.

The purpose of public health activities is to provide conditions in which people can be healthy that requires the participation of other sectors and the community. But in our country, the training of public health personnel has been mainly focused on some diseases and maternal and child health care. Services provided by public health graduates are focused on individuals, while public health services, according to its definition and examples in developed countries, should be population-based. According to the real needs of the community and health staff, it is necessary, in the context of the education transformation plan and in line with responsive and community-based education, to revise the curriculum of this field, by emphasizing training individual care and public health services in order to train two separate groups of health professionals.
