ObjectivesTo investigate the impact of gender on multimorbidity in northern Iran.DesignA cross-sectional analysis of the Golestan cohort data.SettingGolestan Province, Iran.Study population49 946 residents (age 40–75 years) of Golestan Province, Iran.Main outcome measuresResearchers collected data related to multimorbidity, defined as co-existence of two or more chronic diseases in an individual, at the beginning of a representative cohort study which recruited its participants from 2004 to 2008. The researchers utilised simple and multiple Poisson regression models with robust variances to examine the simultaneous effects of multiple factors.ResultsWomen had a 25.0% prevalence of multimorbidity, whereas men had a 13.4% prevalence (p<0.001). Women of all age-groups had a higher prevalence of multimorbidity. Of note, multimorbidity began at a lower age (40–49 years) in women (17.3%) compared with men (8.6%) of the same age (p<0.001). This study identified significant interactions between gender as well as socioeconomic status, ethnicity, physical activity, marital status, education level and smoking (p<0.01).ConclusionPrevention and control of multimorbidity requires health promotion programmes to increase public awareness about the modifiable risk factors, particularly among women.
A recent study showed an association between hookah/opium use and gastric cancer but no study has investigated the relationships with gastric precancerous lesions. We examined the association between hookah/opium and gastric precancerous lesions and subsequent gastric cancer. In a population-based cohort study, 928 randomly selected, healthy, Helicobacter pylori infected subjects in Ardabil Province, Iran, were followed for 10 years. The association between baseline precancerous lesions and lifestyle risk factors (including hookah/opium) was analyzed using logistic regression and presented as odds ratios (ORs) and 95% confidence intervals (CIs). We also calculated hazard ratio (HRs) and 95%CIs for the associations of lifestyle risk factors and endoscopic and histological parameters with incident gastric cancers using Cox regression models. Additionally, the proportion of cancers attributable to modifiable risk factors was calculated. During 9,096 person-years of follow-up, 36 new cases of gastric cancer were observed (incidence rate: 3.96/1000 persons-years). Opium consumption was strongly associated with baseline antral (OR:3.2;95%CI:1.2–9.1) and body intestinal metaplasia (OR:7.3;95%CI:2.5–21.5). Opium (HR:3.2;95%CI:1.4–7.7), hookah (HR:3.4;95%CI:1.7–7.1) and cigarette use (HR:3.2;95%CI:1.4–7.5), as well as high salt intake, family history of gastric cancer, gastric ulcer and histological atrophic gastritis and intestinal metaplasia of body were associated with higher risk of gastric cancer. The fraction of cancers attributable jointly to high salt, low fruit intake, smoking (including hookah) and opium was 93% (95%CI:83–98). Hookah and opium use are risk factors for gastric cancer, as well as for precancerous lesions. Hookah, opium, cigarette and high salt intake are important modifiable risk factors in this high incidence gastric cancer area.
Advances in medicine and health policy have resulted in growing of older population, with a concurrent rise in multimorbidity, particularly in Iran, as a country transitioning to a western lifestyle, and in which the percent of the population over the age of 60 years is increasing. This study aims to assess multimorbidity and the associated risk factors in Iran.We used data from 50,045 participants (age 40–75 y) in the Golestan Cohort Study, including data on demographics, lifestyle habits, socioeconomic status, and anthropometric indices. Multimorbidity was defined as the presence of 2 or more out of 8 self-reported chronic conditions, including cardiovascular diseases, diabetes, chronic obstructive pulmonary disease, chronic kidney disease, liver disease, gastroesophageal reflux disease, tuberculosis, and cancer. Multivariate logistic regression models were used to examine the associations between multiple different factors and the risk factors.Multimorbidity prevalence was 19.4%, with the most common chronic diseases being gastroesophageal reflux disease (76.7%), cardiovascular diseases (72.7%), diabetes (25.3%), and chronic obstructive pulmonary disease (21.9%). The odds of multimorbidity was 2.56-fold higher at the age of >60 years compared with that at <50 years (P < 0.001), and 2.11-fold higher in women than in men (P < 0.001). Other factors associated with higher risk of multimorbidity included non-Turkmen ethnicity, low education, unemployment, low socioeconomic status, physical inactivity, overweight, obesity, former smoking, opium and alcohol use, and poor oral health.Apart from advanced age and female sex, the most important potentially modifiable lifestyle factors, including excess body weight and opium use, and opium user, are associated with multimorbidity. Policies aiming at controlling multimorbidity will require a multidimensional approach to reduce modifiable risk factors in the younger population in developing countries alongside adopting efficient strategies to improve life quality in the older population.
FI was a prevalent condition in Iranian middle-aged women. Future efforts should be aimed at screening FI in women, offering services to treat them, reducing personal and complication-related costs, and improving their quality of life.
Despite all recent treatment advances and the worldwide decline in the incidence rate, gastric cancer (GC) remains an ongoing global health challenge and one of the major leading causes of cancer-specific deaths, particularly in high-incidence regions including Iran. Since GC is often diagnosed in advanced stages, the best action may be to enable early diagnosis of the disease or even prevent it in the first place through identification and control of the underlying risk factors. Endoscopy, as the gold standard method, is both expensive and invasive, making it an unfavorable device in this regard. Therefore, it is crucial to implement a reliable region-specific screening and surveillance program to identify high-risk individuals with more efficient screening modalities. Here, in addition to a review of current GC knowledge, we presented the data of newly-established Population-based Cancer Registries (PBCRs) in Iran. Our assessment confirmed earlier reports of a very high GC incidence rate in the northwestern and northern provinces of Iran, most notably Ardabil. Along with the important role of conventional risk factors such as Helicobacter pylori (HP) infection and high dietary intake of salt, of more interest, we highlighted new region-specific risk factors, namely hookah, and opium. In conclusion, it seems the best results in reducing GC incidence and mortality rates on larger scales arise from modifying behavioral and environmental risk factors and advancing genetic and molecular biomarkers in order to supersede endoscopy. Regular endoscopic screening and antibiotic chemoprophylaxis against HP are still more appropriate in high-risk groups with specified criteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
