Hepatocellular carcinoma incidence at national and provincial levels in Iran from 2000 to 2016: A meta-regression analysis.

ABSTRACT:

Background

The incidence of Hepatocellular carcinoma (HCC), the most common primary liver cancer with high mortality, is undergoing global change due to evolving risk factor profiles. We aimed to describe the epidemiologic incidence of HCC in Iran by sex, age, and geographical distribution from 2000 to 2016.

Methods

We used the Iran Cancer Registry to extract cancer incidence data and applied several statistical procedures to overcome the dataset's incompleteness and misclassifications. Using Spatio-temporal and random intercept mixed effect models, we imputed missing values for cancer incidence by sex, age, province, and year. Besides, we addressed case duplicates and geographical misalignments in the data.

Results

Age-standardized incidence rate (ASIR) increased 1.17 times from 0.57 (95% UI: 0.37-0.78) per 100,000 population in 2000 to 0.67 (0.50-0.85) in 2016. It had a 21.8% total percentage change increase during this time, with a 1.28 annual percentage change in both sexes. Male to female ASIR ratio was 1.51 in 2000 and 1.57 in 2016. Overall, after the age of 50 years, HCC incidence increased dramatically with age and increased from 1.19 (0.98-1.40) in the 50-55 age group to 6.65 (5.45-7.78) in the >85 age group. The geographical distribution of this cancer was higher in the central, southern, and southwestern regions of Iran.

Conclusion

The HCC incidence rate increased from 2000 to 2016, with a more significant increase in subgroups such as men, individuals over 50 years of age, and the central, southern, and southwestern regions of the country. We recommend health planners and policymakers to adopt more preventive and screening strategies for high-risk populations and provinces in Iran.

Project description:BackgroundThe increasing trends in Diabetes prevalence and its attributed burden emphasized as an important issue that needs serious and urgent attention, all over the word. We estimated the mean Fasting Plasma Glucose (FPG) and the prevalence of Diabetes in aged 25 years or older Iranian adults, by sex, age, province, and year through the time period of 1990 to 2016.MethodsIn order to access the most comprehensive relevant data at the same time the systematic data searched added to the data of 5 national surveys and 7 sub-national population based investigations. Two round of modeling, including the Age-Spatio-Temporal and Gaussian Process Regression were used for estimation of mean FPG trend and uncertainties. To estimate Diabetes estimations in target groups, a crosswalk model was applies to the FPG estimates. The model reiterated separately for women and men. All of estimations standardized based on the Iran national census population of 2016 by year, age groups and sexes at national and sub-national levels.ResultsIn 2016, the number of the diabetic population was 4.43 (3.93-4.99) million (2.38 million women). Between 1990 and 2016, the age-standardized mean of FPG increased from 84.69 mg/dl (79.8-89.8) to 100.5 mg/dl (97.9-103.3) in women and from 82.7 mg/dl (78.3-87.5) to 98.8 mg/dl (96.2-101.4) in men. Simultaneously, with considerable difference, the Diabetes prevalence, has increased from 6.1% (4.7-7.8) to 9.8% (8.7-11.1) in women and from 5.0% 18 (3.8-6.3) to 8.1% (7.2-9.2) in men (75% attributed to population growth). Considering the geographical patterns, the greatest increment in the prevalence of Diabetes detected in the northwestern and the central provinces.ConclusionSignificant increasing trends of Diabetes led to alarming threat, which can make the strategies and goals of our prevention programs out of control. We should plan for more effective communicative interventions for prevention and management of Diabetes, to be designed, implemented and monitored based on the updated scientific evidence.Supplementary informationThe online version contains supplementary material available at 10.1007/s40200-023-01197-2.

Project description:BackgroundOne fifth of the global burden of cardiovascular diseases (CVDs) in 2017 was attributable to excessive salt intake. As a member of the World Health Organization (WHO), Iran has committed itself to a 30% reduction in salt intake by 2025. Evidence on the amount and trend of salt intake among the Iranian population at national and sub-national levels is scarce. This study aimed to estimate the Iranian population's salt intake during 2000-2016 at the national and sub-national levels, by sex and age groups.MethodsData on national and sub-national mean salt intake was obtained through systematically searching the literature and contacting the research studies' principal investigators. Data collected through various methods were harmonized using the cross-walk method. Bayesian hierarchical and spatio-temporal-age regression models and simulation analysis were used to estimate the mean salt intake and its uncertainty interval across sex, age, year, and province.ResultsNational age-sex standardized mean salt intake decreased from 10·53 g/day (95% uncertainty interval [UI]: 10·2 to 10·9) in 2000 to 9·41 (9·2 to 10·6) in 2016 (percent change: - 9·8% [- 21·1-3·1]). The age-standardized mean salt intake in women had decreased from 9·8 g/day (95% UI: 9·0-10·6) in 2000 to 9·1 g/day (8·6-9·7) in 2016 (percent change: - 6·6% [- 19·0-7·9]). The same measure in men was 11·1 g/day in 2000 (95% UI: 10·3-11·8) and 9·7 g/day (9·1-10·2) in 2016 (percent change: - 12·7% [- 23·0 - -0·9]). Age-sex standardized mean salt intake at the sub-national level in 2016 varied from 8·0 (95% UI: 7·0-9·0) to 10·5 (10·0-11·1). The difference between the provinces with the highest and the lowest levels of salt intake in 2016 was 31·3%.ConclusionSalt intake decreased in Iran from 2000 to 2016, while persistently exceeding the recommended values. This declining trend was more pronounced between 2010 and 2016, which might be attributed to Iran's compliance to WHO's Action Plan for reducing NCDs.
