Abstract
OBJECTIVES
Dietary factors play an important role in modifying cancer risk. This study aimed to assess the proportion of cancer incidence and mortality in Korea attributable to dietary factors from 2015 to 2030.
METHODS
We estimated the population-attributable fraction (PAF) of cancer incidence and mortality using dietary intake levels, exposure rates, and relative risks (RRs). Intake and exposure rates were derived from the Korean National Health and Nutrition Examination Survey, assuming a 15-year latency. RRs were obtained from meta-analyses of Korean cohort and case- control studies.
RESULTS
In 2020, 6.08% of cancer cases and 5.70% of deaths in Korea were attributable to dietary factors. High salted vegetable intake (2.12% for incidence and 1.78% for deaths) and low intake of non-starchy vegetables and fruits (1.92 and 2.34%, respectively) were major contributors. However, high intakes of red meat and processed meat showed low PAFs, each less than 1%. The projected PAF for cancer attributable to high salted vegetable intake is expected to decrease substantially to 1.17% in 2030. In contrast, the PAF linked to low intake of non-starchy vegetables and fruits is projected to remain relatively stable.
CONCLUSIONS
Our findings provide evidence that dietary factors make a substantial contribution to cancer incidence and mortality in Korea. This study highlights that reducing salted vegetable intake and encouraging a diet rich in non-starchy vegetables and fruits may support cancer prevention efforts. Continuous monitoring of dietary trends remains crucial for reducing the cancer burden.
Summary
Korean summary
2020년 기준으로 식이 요인은 암 발생과 사망의 일정 비율을 차지하였으며, 여러 식이 요인 중에서는 염장채소의 높은 섭취와 비전분 채소 및 과일의 낮은 섭취가 상대적으로 높은 기여를 보였다. 이러한 결과는 식이 요인별 암 부담의 차이를 이해하고, 향후 식이 섭취 양상에 대한 지속적인 관찰과 공중보건적 검토의 필요성을 시사한다.
Key Message
In 2020, dietary factors accounted for a proportion of the cancer burden, with high intake of salted vegetables and low intake of non-starchy vegetables and fruits showing the largest contributions among dietary factors examined. These findings suggest the need for continued assessment of dietary patterns and their potential relevance in public health discussions on cancer prevention.

Abstract
OBJECTIVES
This study investigated whether adherence to the overall lifestyle recommendations in the American Cancer Society (ACS) guidelines on nutrition and physical activity for cancer survivors was associated with inflammation in breast cancer survivors.
METHODS
The study included 409 women who had undergone breast cancer surgery at least 1 year before enrollment. A generalized linear model was used to estimate the least square means and 95% confidence intervals of plasma levels of inflammatory markers according to lifestyle factors defined in terms of adherence to the ACS guidelines.
RESULTS
Higher overall adherence scores were associated with lower levels of high-sensitivity C-reactive protein (hs-CRP) (p for trend=0.015) and higher levels of adiponectin (p for trend=0.009). Similar significant associations of hs-CRP (p for trend= 0.004) and adiponectin (p for trend=0.010) levels were observed with the score for the body mass index (BMI) component of the adherence score. A higher diet component score was associated with a higher adiponectin level (p for trend=0.020), but there was no significant association for the physical activity component score.
CONCLUSIONS
The present study’s findings suggest that maintaining a healthy lifestyle according to the ACS guidelines was associated with beneficial effects on inflammatory marker levels, especially hs-CRP and adiponectin, among breast cancer survivors. Among the 3 components of lifestyle guidelines, the BMI component exhibited the most similar tendency to the overall adherence score in relation to inflammatory indicators. Further prospective and intervention studies are needed to investigate longitudinal associations between lifestyle factors and inflammatory markers among breast cancer survivors.
Summary
Korean summary
- 한국인 유방암 생존자를 대상으로 한 연구에서, 암 생존자를 위한 영양 및 신체 활동에 관한 미국암협회 (American Cancer Society, ACS) 지침을 따라 건강한 생활 습관을 유지하는 것이 혈중 염증 마커 수준, 특히 낮은 hs-CRP와 높은 adiponectin 수준과 관련이 있었습니다.
- 체질량지수 (Body Mass Index, BMI)를 적절한 수준 (18.5-23 kg/m²)으로 유지하는 것은 낮은 hs- CRP 수준과 높은 adiponectin 수준과 관련이 있는 것으로 나타났습니다.
- 또한, 과일, 야채 및 통곡물이 풍부하고 적색육 및 가공육을 적게 섭취하는 건강한 식단은 혈중 adiponectin 수치가 높은 것과 관련이 있었습니다.
Key Message
• Maintaining a healthy lifestyle according to the American Cancer Society (ACS) Guidelines on Nutrition and Physical Activity for Cancer Survivors was associated with favorable levels of inflammatory markers, especially in hs-CRP and adiponectin among breast cancer survivors.
• Maintaining an adequate BMI of 18.5 to 23 kg/m2 was associated with lower levels of hs-CRP and higher adiponectin levels.
• In addition, a healthy diet — indicating a diet high in fruits, vegetables, and whole grains, and low in red and processed meats — was associated with higher adiponectin levels.
