Background: The relationship between food insecurity and mental and physical components of health-related quality of life (HRQOL) has been less addressed by healthcare professionals. Objective: We aimed to investigate the relationship between household food insecurity and mental and physical components of HRQOL in a large sample of urban people and to determine whether household food insecurity has a negative effect on mental and physical components of HRQOL. Methods: This cross-sectional study was conducted across twenty-two districts of Tehran (capital of Iran) during 2011. The participants were selected through multistage cluster random sampling. Two questionnaires were used to measure household food insecurity and HRQOL in the study population, while descriptive and inferential statistics were applied to test the relationships between these two parameters. Results: The mean age of the study population was 44.5 ± 15.5 years and most were female (64.8%). The results of this study indicated an independent relationship between household food insecurity and different subscales of HRQOL (P Conclusion: Food insecurity was associated with mental and physical components of HRQOL among urban participants and can be considered as a part of comprehensive interventions that target to improve general health.

There is a direct association between salt intake and blood pressure (BP), one of the main risk factors for CVDs. However, yet there has been a debate that how strong is this association in people with and without hypertension. This study was conducted to evaluate the magnitude of the association between salt intake and BP in hypertensive and normotensive population among a nationally representative population. The study was conducted on a nationally representative sample of 18,635 Iranian adults aged 25 years and older who participated in the STEPS survey 2016 and provided urine sample. Salt intake was estimated through spot urine sample and Tanaka equation. Multiple linear regression model in survey data analysis was used to assess the independent effect of salt intake on BP. After adjusting for covariates, there was a significant association between salt intake and SBP in hypertensive (p

There is a direct association between salt intake and blood pressure (BP), one of the main risk factors for CVDs. However, yet there has been a debate that how strong is this association in people with and without hypertension. This study was conducted to evaluate the magnitude of the association between salt intake and BP in hypertensive and normotensive population among a nationally representative population.The study was conducted on a nationally representative sample of 18,635 Iranian adults aged 25 years and older who participated in the STEPS survey 2016 and provided urine sample. Salt intake was estimated through spot urine sample and Tanaka equation. Multiple linear regression model in survey data analysis was used to assess the independent effect of salt intake on BP.After adjusting for covariates, there was a significant association between salt intake and SBP in hypertensive (p 0.001) and normotensive people (p 0.001). In hypertensive people, with 1 g of increase in salt intake, the SBP and DBP increased 0.37 mmHg and 0.07 mmHg, respectively. Whereas in normotensive people, with 1 g of increase in salt intake, the SBP and DBP increased 0.26 mmHg and 0.05 mmHg, respectively. Moreover, there was a significant trend toward an increase of SBP across salt intake quartiles in both hypertensive (p 0.001) and normotensive people (p = 0.002), though the slope was steeper in hypertensive than in normotensive people.The present study demonstrated that salt intake significantly increased SBP in both hypertensive and normotensive people, though the magnitude of this increase was greater in hypertensive people as compared with normotensive people.

Background: Food insecurity as a major public health problem has associations with a wide range of adverse consequences on health and quality of life. The aim of this study is to determine the prevalence of food insecurity among Iranian households, its key socioeconomic risk factors and population attributable risk via a large-scale cross-sectional study in the capital of Iran. Methods: This cross-sectional study was performed among 30,809 households with complete questionnaires of food security, during 2011. The univariate test was used to investigate the association between economic status and covariates with household food insecurity. Multiple logistic regression model was used to assess the independent effect of economic status on household food insecurity. Results: Totally, 37.8% (95% CI: 37.25, 38.34%) of the households were food insecure. There were significant associations between economic status and household food insecurity after adjustment for other variables (p-value
