Global distribution, risk factors, and recent trends for cervical cancer: A worldwide country-level analysis.

This study aimed to evaluate the most updated worldwide distribution, risk factors, and temporal trends of cervical cancer for different countries and age groups. The Global Cancer Observatory database was retrieved for the age-standardized rates (ASRs, per 100,000 persons) for incidence and mortality of cervical cancer in 2018. The associations with risk factors were examined by multivariable regression analysis, adjusting for human development index (HDI) and gross domestic products (GDP) per capita. Joinpoint regression analysis was used to calculate the 10-year annual average percent change (AAPC) for incidence and mortality. A total of 568,847 new cases (ASR, 13.1) and 311,365 deaths (ASR, 6.9) of cervical cancer were reported globally in 2018. The highest incidence and mortality were observed in Southern Africa (ASRs, 43.1 and 20.0) and countries with low HDI (ASRs, 29.8 and 23.0). Countries with higher incidence and mortality had lower HDI (β = −8.19, 95% CI -11.32 to −5.06, p < 0.001; β = −7.66, CI -9.82 to −5.50; p < 0.001) but higher alcohol consumption (β = 1.89, 95% CI 0.59 to 3.19, p = 0.005; β = 0.98, CI 0.08 to 1.88; p = 0.033). An increasing trend of incidence was also observed in younger populations, with Cyprus (AAPC, 6.96), Sweden (AAPC, 4.88), and Norway (AAPC, 3.80) showing the most prominent. The burden of cervical cancer was highest in regions with low and medium HDI and was associated with higher prevalence of alcohol consumption. There was an overall decreasing burden of cervical cancer; however, an increase in incidence and mortality was observed in some populations. More intensive preventive strategies are recommended for these populations. • The burden of cervical cancer was highest in regions with low and medium HDI and higher alcohol consumption. • The incidence and mortality of cervical cancer have been declining globally for the recent past decade. • However, an increasing incidence trend was observed in North European countries and among younger females. • Further studies are needed to explore the reasons underlying these epidemiological transitions.
