RESUMEN
Osteoporosis is a widespread disease among older peoples. The aim of this study is to estimate the prevalence of self-reported osteoporosis and assessing its association with socio-economic status. A population-based cross-sectional study was conducted in Tehran, Iran in 2011. Participants were 45,990 individuals aged above 20 years from 22 urban districts. Osteoporosis was measured by self-administrative questionnaire. Wealth index was constructed using principal component analysis based on household assets. Chi-square test, chi square test for trend, and crude odds ratio were used to assess associations in univariate analysis. Multiple logistic regression utilized to estimate adjusted associations between self-reported osteoporosis and socio-economic status.The overall estimated prevalence of self-reported osteoporosis was 4% (95% CI 3.88-4.13), 1.19% in men, and 6.84% in women (P < 0.001). The prevalence increased considerably as age increased (P for trend < 0.001). In multivariable analysis, education and wealth status were negative, and smoking was positively associated with the prevalence of self-reported osteoporosis. No association was found between participants' skill levels and Townsend deprivation index with the prevalence of self-reported osteoporosis.The findings of the present study have improved understanding of the association between socioeconomic status and osteoporosis in the Iranian population. It is important to consider socioeconomic status in screening and prevention programs.

OBJECTIVE: To assess the prevalence of dental pain in the past year among adults in Tehran-Iran, and its determinants. BASIC RESEARCH DESIGN: Cross-sectional population study. PARTICIPANTS: A sample of 20,322 adults (18-64 years old). METHODS: A questionnaire survey was conducted across the 22 districts using the multi-stage random sampling method. Data were analysed applying the complex samples method. Multiple logistic regression analysis was used to adjust the effects of other variables on the outcome variable as dental pain in the past year. RESULTS: Overall, 19,645 individuals with a mean age of 39.9 (SD=12.5) years responded. Dental pain in the past year was reported by about one sixth (14%) of subjects and associated with being widowed/divorced (OR 1.45, 95%CI 1.07-1.97, p=0.016), married (OR 1.24, 95%CI 1.04-1.47, p=0.016), Azari minority (OR 1.2, 95%CI 1.05-1.37, p=0.009) and having dental visit in the past year (OR 2.6, 95%CI 2.29-2.95,p⟨0.001). Older subjects (OR 0.76, 95%CI 0.59-0.97, p= 0.029), those with a high economic status (OR 0.84, 95%CI 0.72-0.98, p=0.03), good (OR 0.75, 95%CI 0.58-0.96, p=0.023) or moderate oral health behaviour (OR 0.79, 95%CI 0.62-0.99, p=0.042), and good self-perceived oral health (OR 0.52, 95%CI 0.45-0.61, pp⟨0.001) were less likely to report dental pain. CONCLUSIONS: Dental pain in the past year was associated with being married/widowed, being a minority, and visiting a dentist in the past year. Older subjects and those with a high socio-economic status, good/moderate oral health behaviour, and good self-perceived oral health were less likely to report dental pain.

INTRODUCTION: Diabetes mellitus is an important public health challenge worldwide. The prevalence of type 2 diabetes varies across countries. The aim of this study is to estimate the prevalence of type 2 diabetes and to determine related factors including socioeconomic factors in a large random sample of Tehran population in 2011. METHODS: In this cross-sectional study, 91,814 individuals aged over 20 years were selected randomly based on a multistage, cluster sampling. All participants were interviewed by trained personnel using standard questionnaires. Prevalence and Townsend deprivation indexes were calculated. Principal component analysis (PCA) was used to construct wealth index. Logistic regression model was used in multivariate analysis. RESULTS: The estimated prevalence of self-reported diabetes was 4.98 % overall, 4.76 %in men and 5.19 % in women (P < 0.003). In multivariate analysis, age, marital status (married and divorced/widow) and BMI were positively associated with the prevalence of self-reported diabetes. Of the socioeconomic variables, educational level and wealth status were negatively and Townsend Index was positively associated with diabetes. CONCLUSION: Our study findings highlight low reported prevalence of diabetes among adults in Tehran. Subjects with low socioeconomic status (SES) had a higher prevalence of type 2 diabetes. Weight gain and obesity were the most important risk factors associated with type 2 diabetes. Wealth index and educational level were better socioeconomic indicators for presenting the inequality in diabetes prevalence in relation to Townsend deprivation index.

OBJECTIVES: Social capital is associated with a number of sociodemographic characteristics and health outcomes. This study aimed to assess the components of social capital, and determine its association with different demographic features and general health in Tehran. STUDY DESIGN: A large population-based cross-sectional survey was conducted using the Urban Health Equity Assessment and Response Tool (Urban-HEART). METHOD: A comprehensive questionnaire containing 13 sections, including a specific tool to measure social capital, was administered to 22,300 randomly selected clustered sample households within all 22 districts in Tehran between June and September 2008. The social capital questionnaire consists of two main components - structural and cognitive - which measure collective activities, voluntary help, social cohesion, social network, reciprocity and trust. The first question of Short Form-12 was used to evaluate self-rated health. Descriptive statistics, contingency tables, independent sample t-test, analysis of variance, post-hoc test (least squares difference) and multiple linear regression were used to detect differences. A P-value <0.01 was considered to indicate significance. RESULTS: The social capital questionnaire and health-related quality-of-life tool were completed by 21,704 individuals (response rate 97%) in all 22 districts of Tehran. All social capital components apart from participation varied by age group and gender (P < 0.01). An improvement was seen in several social capital components with increased level of education (P < 0.01). All social capital elements apart from volunteering were associated with marital status (P < 0.01). Family size, family assets and length of residence in neighbourhood were considered to be determinants of social capital (P < 0.01), and respondents with better health showed higher levels of social capital (P < 0.0001). CONCLUSION: Various individual and household characteristics influence social capital. General health and social capital are mutually and independently correlated with other determinants, so improvements in either may lead to higher levels of social capital and well-being.

INTRODUCTION: Despite considerable achievements in the provision of basic developmental facilities in terms of drinking water, access to primary healthcare services, high-quality and nutritious food, social services, and proper housing facilities, there are many rural and slum communities in Iran where these essential needs remain unfulfilled. Lack of equity is prominent, as large differences exist in underprivileged provinces. New policies developed in the past two decades have resulted in substantial achievements in meeting population needs and reducing the socio-economic gap; nevertheless, poverty levels, unemployment due to a large increase in the birth rate in the early 1980s, and lack of community participation are matters yet to be addressed. To overcome these deficiencies, a basic development needs approach was adopted to promote the concept of community self-help and self-reliance through intersectoral collaboration, creating an environment where people could take an active part in the development process, with the Iranian government providing the necessary support to achieve the desired level of development. DESCRIPTION OF THE PROJECT: Following firm commitment from the Iranian government and technical support from the World Health Organization Regional Office, basic development needs was assigned a high priority in health and health-related sectors, reflected in the third National Masterplan (2001-2005). A comprehensive intersectoral plan was designed, and pilot projects were commenced in three villages. Each village elected a representative, and committee clusters were formed to run and monitor projects identified by a process of local needs assessment and priority assignment. In each region, a variety of needs were elicited from these assessments, which were actively supported by local authorities. LESSON LEARNED: A basic development needs approach was found to be a reliable discipline to improve community participation, needs-led resource allocation and intersectoral co-operation in community development, particularly in underprivileged areas. Iran's initial experience of basic development needs has gained widespread public support but will require periodical evaluation as it is introduced into other rural and urban regions across the country.

In an isolated and founding Iranian population the prevalence of congenital total blindness is 1.1%. Clinical findings such as lack of perception of light, massive retrolental mass, shallow anterior chamber and nystagmus, in otherwise normal individuals, correspond to nonsyndromal congenital retinal nonattachment. To determine the inheritance of this disease we constructed an extensive nine-generation pedigree of the affected kindred living in the Iranian founding population. The pedigree, which includes 42 patients from 25 sibships, clearly suggests autosomal recessive inheritance. To verify the inheritance, we compared the average coefficient of inbreeding (F) of the affected sibships with that of the control sibships, calculated the patients' sex ratio, and also compared the observed relative frequency of the disease with its expected relative frequencies for different modes of inheritance. The patients' average F value is significantly greater than that of the controls (P < 0.001). The sex ratio of the patients is close to unity and the observed relative frequency of the disease is close to that of an autosomal recessive trait. All these findings strongly support autosomal recessive transmission of this disease.
