BACKGROUND: Risk perception is an important predictor to mitigate climate change effects which can produce mental health consequences such as anxiety and depression. For developing policies of climate risk adaptation, awareness of public attitudes, beliefs, and perception is essential. At this study, researchers tried to focus on the often “unseen” psychological aspects of climate change. MATERIALS AND METHODS: A qualitative approach was done with a consistent content analysis method. The study consisted of 33 participants including ordinary people and experts in disasters and climate change. Purposeful sampling was adopted until data saturation. The data collection was performed through in-depth and semi-structured interviews. All interviews were transcribed after listening again and again and reading several times to catch an overall understanding of the interviews. RESULTS: The main theme of the study was “Complexity nature of climate change risk perception” and related categories including “the Mental health dimension,” “the Cognitive dimension” and “Interaction of imposed components.” The structure of the research community strongly reflected effects of cultural and religious factors in all aspects of community life. Participants’ life experiences of extreme events were associated to their perception of climate change. CONCLUSIONS: Risk perception is multifactorial and complicate and should clearly be understood to improve community participation to manage climate change-related risks. We propose that authorities and related managers should pay attention to it as a priority. This may assist in developing research on public mental health practices.

Retinopathy of prematurity (ROP) is an ophthalmologic condition that is one of the leading causes of preventable childhood blindness. Due to the premature nature of blood vessels in preterm infants, retinal vessels are prone to damage. The incidence of ROP ranges with great variation across countries, and this study aims to identify the incidence and its related risk factors.A compilation of studies investigating the incidence of ROP was acquired through the PubMed and Google Scholar databases with a full free text in English filter set. All members of the study were involved in designating studies based on continent and arranging them into a table format. Following this, reasons for the variation in the incidence of ROP were investigated by individually assessing each study. The variation of an increased incidence of ROP seen in low-income countries (LICs) was most likely due to the availability of resources. As a preterm birth can give rise to further complications such as the development of sepsis, it is important to manage preterm birth with the utmost caution. Evidence has suggested that the two key variables in reducing the morbidity and mortality of ROP are the implementation of a screening and treatment protocol with controlled use of oxygen and the availability of resources in hospitals to adequately identify and manage ROP as early as possible.Through a comprehensive overview of the incidence of ROP, it is vital to review screening and treatment protocols in each hospital for ROP, which would aid in preventing its occurrence and initiating early treatment.
