Healthy city approach examines the quality of life of the people of a society from the environmental aspect, community health, individual and social living environment, social welfare, etc. In this descriptive-analytical research, with the aim of identifying the indicators of a healthy city, the environmental situation of Tehran was evaluated and compared.

The statistical population is selected Asian cities and 22 districts of Tehran. The status of each of the indicators has also been collected separately from library sources and organizational references. At first, in order to determine and recognize the degree of proximity of Tehran city to the indicators of a healthy city, using the fuzzy network analysis model and Vicor ranking model, the position of this city among selected Asian cities was determined and prioritized. Then, by referring to the specific weights of the indicators and Vicor model, the ranking of each of the 22 districts of Tehran was done, in order to determine the importance of each of them in the current situation of Tehran.

The obtained results indicate that Tehran ranks sixth among the selected Asian cities, but it has a lower rank in all the examined criteria than the average values ​​obtained. Among the regions of Tehran, this survey also showed that regions 22, 18 and 6 are in the best condition and regions 9, 10 and 12 are in the worst condition.

These results show that Tehran has taken steps towards achieving the indicators of a healthy city, but due to various reasons, it has not been able to achieve these indicators in 22 regions with tasteful management. The proposed strategy is an adaptive approach and improving governance capacity.

Urban managers and designers are looking for ways to solve problems caused by population growth and increasing migration to large cities. Designing new cities on the outskirts of metropolitan areas to accommodate their overflowing population is one of these solutions. However, new cities will face demographic and ecological crises caused by rapid growth and sudden influx of population without purposeful and organized control and proper infrastructure. Developing new cities was first approved in 1985 as a policy to curb the uncontrolled population growth and migration to large cities in Iran. New cities are mainly developed to ensure proportional distribution of population in the desired urban area, decentralization of the metropolis, improvement of living and service standards, and prevention of unreasonable increase in land and housing prices. In accordance with the policies assigned for the development of new cities and serious restrictions on further development of Tehran metropolitan area especially on agricultural lands, and due to the high slope of land in the northern parts of the city, high groundwater level and inadequate soil penetration resistance in the southern parts of the city, the city being earthquake-prone, existing restrictions on the development of infrastructure, facilities, transportation network and water supply, inversion phenomenon and limitations the ecosystem will face with more population, development of 5 new cities in the suburban area of Tehran was approved by authorities.

Questionnaire and interview-based survey methods have been used in the present descriptive and analytical study. Data collection was performed using documentary and field study methods. Qualitative research techniques and content analysis tools have been used to select commonly used important research indicators from related literature. Following data collection from relevant organizations and institutions, a binary comparison questionnaire was prepared for each group of criteria. Using the Delphi method, urban planning experts were asked to comment on these tables. To evaluate and weight the obtained criteria, AHP method and Expert Choice 11 were used and the average was calculated in EXCEL. Pardis was selected as the case study to evaluate the opinions of new cities' residents. In survey and field study, tools such as questionnaires, interviews and observations were used to investigate the social and economic status in the new city of Pardis. A questionnaire was prepared based on Likert five-point scoring scale to determine the level of satisfaction in residents of Pardis city and to see whether in practice residents benefit more from the criteria assigned a higher weight by experts. The questionnaire was randomly distributed among 450 people and the results were evaluated in SPSS.

Findings indicate that proximity to the capital, acceptable roads, fair weather condition, fewer traffic jams, and lower house prices are among the reasons for satisfaction of Pardis residents. However, previous residents of Tehran expect a living standard similar to living standards in this city so there is still a long road ahead for Pardis city to fulfil its basic plans of offering settlements and employment for at least a population of 200 thousands and obviating the need for daily commutes. Findings indicate that 40% of the employed population commute daily which results in dissatisfaction and an unnecessary increase in household monthly expenses while turning the city into an unproductive dormitory town. Based on what was analyzed theoretically in the present study, as well as our knowledge of the prosperity, dynamism, population, and civilization level of new cities, it seems that a technocratic view based on instrumental rationality in a rent-seeking economy has ultimately led into the present situation in which large-scale urban development projects have been reduced into a series of housing projects. Therefore, various social issues and the problem of identity and dynamism have become a major issue in the urban system of new cities. However, paying attention to vitality and sustainable social development, as well as reviewing and redefining patterns and procedures have made an important turning point and created the required capacity for urban development management and foresight which shall be expanded to reach a useful executive plan and develop its theoretical and practical basis.

Results indicate that the new city of Pardis has achieved objectives of the detailed plan to some extent, but poor infrastructure, lack of sufficient number of employments for the households and lack of economic dynamism have created a city dependent on external employment and thus failing to achieve the utmost goals of the plan.

 Several studies have been conducted on the effects of floods on the health of the affected community. We aimed to determine the effects of floods as the most common disaster on hypertension (HTN) as one of the most common noncommunicable diseases (NCDs).

Four databases including Medline, Scopus, Google Scholar, and ScienceDirect were searched with the search strategy protocol up to the end of June 2021 and with the keywords of flood and high blood pressure or hypertension. Grey literature database and websites of WHO, UNDRR, and PreventionWeb were also searched. After removing duplicate articles, abstracts of the relevant titles were reviewed, and eligible articles were included for full-text review. Finally, the study variables were extracted from selected articles.

The search strategy resulted in eight final relevant articles from 48,980 articles. All final articles noted meaningful effect of flood on high blood pressure. There was a positive correlation between anxiety level, property loss, financial loss, physical activity, use of alcoholic beverages, interruption of medication, and medical cares with HTN. Different studies have also reported long-term effects of flooding on blood pressure.

The flood has significant effect on high blood pressure in affected population. However, cases of unknown HTN in the affected population should also be considered, so screening is recommended in the affected community
