Abstract
OBJECTIVES
Tobacco smoking is a major public health concern worldwide. This study aimed to assess its impact on cancer incidence and mortality by estimating the population attributable fraction (PAF) in the Korean population for 2015 and 2020 and by projecting future trends until 2030.
METHODS The Korean relative risk (RR) was calculated via a meta–analysis of RRs for individual cancers attributed to tobacco smoking, based on primary data analysis from the Korean Cohort Consortium. The PAF was estimated using the Levin formula with past and current prevalence rates and the number of cancer cases and deaths, assuming a 15–year latency period.
RESULTS The proportions of cancer cases and deaths in Korea attributable to tobacco smoking were similar to those calculated using Asian and global RRs for both men and women. In 2015 and 2020, tobacco smoking contributed to 14.32% and 13.17% of cancer cases and 21.70% and 20.69% of cancer deaths in adults, respectively. Among Koreans, smoking was responsible for 25.83% of new cancer cases in men in 2015, 23.49% in men in 2020, 1.46% in women in 2015, and 1.68% in women in 2020. In both years, smoking impacted mortality more strongly than incidence in Korean men and women (incidence in men: 25.83% and 23.49%; mortality in men: 32.09% and 30.41%; incidence in women: 1.46% and 1.68%; and mortality in women: 4.70% and 4.96%, respectively).
CONCLUSIONS Tobacco smoking causes cancers and deaths in Korea, however, it is preventable. Effective control policies that consider trends and vulnerabilities among women are required.

Abstract
OBJECTIVES
Alcohol consumption is causally linked to several cancers, and major health organizations classify it as a carcinogen. This study assessed the impact of alcohol consumption on cancer incidence and mortality in Korea in 2015 and 2020, projected trends up to 2030, and compared results based on different criteria.
METHODS The relative risk of cancer associated with alcohol consumption in Korea was determined through a meta–analysis of alcohol–related relative risks for specific cancers, using primary data from the Korean Cohort Study within the Korean Cohort Consortium. The population–attributable fraction (PAF) was calculated using Levin's formula, incorporating drinking prevalence and the number of cancer cases and deaths, with a 15–year latency period assumed.
RESULTS In Korea, the PAF for alcohol consumption, based on ever/never drinking criteria, was higher than that calculated using other criteria, except for the PAF based on past and current/never drinking criteria. Alcohol consumption contributed to 3.58% of all cancer cases and 3.28% of cancer deaths in 2015. It accounted for 4.58% of new cancer cases in men and 2.08% in women, with a higher contribution to incidence than mortality (4.00% and 2.25% of cancer deaths in men and women, respectively). Projections indicate that alcohol–related cancer PAF will decrease by 17.2% in men but increase by 70.2% in women by 2030.
CONCLUSIONS This study highlights the impact of alcohol consumption on cancer in Korea, emphasizing the need for sex–specific regulations to address sex differences.

Abstract
OBJECTIVES
This study aimed to determine the population–attributable fractions (PAFs) of cancers using various calculation methods and to estimate the PAFs of cancer incidence and mortality resulting from deficit in physical activity (DPA) from 2015 to 2030, based on data on prevalence rates.
METHODS The PAF of cancer was estimated using a cohort study–based meta–analysis of relative risk (RR), national prevalence rates of DPA from 2000 to 2015, and national cancer statistics from 2015 to 2030, with a latency of 15 years.
RESULTS In 2015, DPA contributed to 909 cancer cases and 548 deaths, accounting for 0.42% and 0.68% of new cancer cases and deaths, respectively. By 2030, the PAF values are expected to increase to 1.31% of incidence and 1.80% of mortality, with a continual increase from 2015 to 2030. When the low metabolic equivalent of task (MET) criteria were selected, the PAF values decreased for both incidence and mortality. The PAF calculated with <900 MET–min/week for the sex–specific MET criterion was higher than that calculated with <900 MET–min/week for both incidence and mortality.
CONCLUSIONS The risk of cancer associated with DPA is expected to rise in both men and women. Future research and strategies should emphasize the promotion of physical activity for cancer prevention, considering its significant implications for public health.
