“…Systolic and diastolic blood pressures for each participant were also measured twice on both arms, with 10-minute intervals, in the sitting position. A wealth score was calculated as described in detail elsewhere (37). Briefly, to build a composite score for wealth, multiple correspondence analysis was used on the variables house ownership, house structure, house size, having a bath in the residence, and occupation, as well as possession of a personal automobile, a motorbike, a blackand-white television, a color television, a refrigerator, a freezer, a vacuum cleaner, and a washing machine.…”

We investigated the association between dairy product consumption and all-cause, cardiovascular disease (CVD), and cancer mortality in the Golestan Cohort Study, a prospective cohort study launched in January 2004 in Golestan Province, northeastern Iran. A total of 42,403 men and women participated in the study and completed a diet questionnaire at enrollment. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals. We documented 3,291 deaths (1,467 from CVD and 859 from cancer) during 11 years of follow-up (2004-2015). The highest quintile of total dairy product consumption (versus the lowest) was associated with 19% lower all-cause mortality risk (hazard ratio (HR) = 0.81, 95% confidence interval (CI): 0.72, 0.91; P trend = 0.006) and 28% lower CVD mortality risk (HR = 0.72, 95% CI: 0.60, 0.86; P trend = 0.005). High consumption of low-fat dairy food was associated with lower risk of all-cause (HR = 0.83, 95% CI: 0.73, 0.94; P trend = 0.002) and CVD (HR = 0.74, 95% CI: 0.61, 0.89; P trend = 0.001) mortality. We noted 11% lower all-cause mortality and 16% lower CVD mortality risk with high yogurt intake. Cheese intake was associated with 16% lower all-cause mortality and 26% lower CVD mortality risk. Higher intake of high-fat dairy food and milk was not associated with all-cause or CVD mortality. Neither intake of individual dairy products nor intake of total dairy products was significantly associated with overall cancer mortality. High consumption of dairy products, especially yogurt and cheese, may reduce the risk of overall and CVD mortality.

Salt tea is the most commonly used beverage in Kashmir, India, where esophageal squamous cell carcinoma (ESCC) is the most common cancer. Salt tea is brewed in a unique way in Kashmir, usually with addition of sodium bicarbonate, which makes salt tea alkaline. As little information about the association between salt tea drinking and ESCC was available, we conducted a large-scale case-control study to investigate this association in Kashmir. We recruited 703 histologically confirmed cases of ESCC and 1664 controls individually matched to cases for age, sex, and district of residence. Conditional logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (95% CIs). Participants who consumed >1,250 ml day 21 showed an increased risk of ESCC (OR 5 2.60, 95% CIs 5 1.68-4.02). Samovar (a special vessel for the beverage preparation) users (OR 5 1.77, 95% CIs 1.25-2.50) and those who ate cereal paste with salt tea (OR 5 2.14, 95% CIs 5 1.55-2.94) or added bicarbonate sodium to salt tea (OR 5 2.12, 95% CIs 5 1.33-3.39) were at higher risk of ESCC than others. When analysis was limited to alkaline tea drinkers only, those who both consumed cereal paste with salt tea and used samovar vessel were at the highest risk (OR 5 4.58, 95% CIs 5 2.04-10.28). This study shows significant associations of salt tea drinking and some related habits with ESCC risk.

Introduction: Cancer is one of the main causes for mortality and morbidity in the world. Identifying epidemiology and the trend of esophageal cancer may be highly effective in related planning. The present study has been carried out with the aim of exploring the morbidity and trend of esophageal cancer in Iran. Methods:The present study is a type of repeated analysis of the existing data. The population of this study consisted of the cancer registry data during the years (2003)(2004)(2005)(2006)(2007)(2008)(2009)) in Iran. The direct incidence rate was standard according to the World Health Organization (WHO) population. The incidence trend of this disease in this country was drawn by the means of the STATA software and the significance of the morbidity trend diagram was also derived via WINPEPI software. Results:The results indicated the increasing trend of esophageal cancer up to 2008 while this trend has been dropping during the years 2008-9. The 31914 cases of esophageal cancer which have been recorded throughout the country out of which this rate has been increased from 2759 cases in 2003 to 6210 cases in 2009 so this rate signifies 2 times in morbidity and the recording of cases. During this 7-year career, the maximum incidence rate was related to the Ardabil province with 19.03 per 100'000 cases in 2009 while the minimum incidence rate was related to Chahar Mahal and Bakhtiari and also Booshehr provinces with 0.48 and 0.42% per 1000 cases in 2003, respectively. Conclusion: The incidence rate of esophageal cancer in Iran is increasing, particularly in the northern and northwestern regions of the country. It is recommended to employ screening programs and premature diagnosis in the regions and among high risk populations.
