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 mean and 95% confidence interval 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=0.0153) and higher levels of adiponectin (p for trend=0.0095). Similar significant associations of hs-CRP (p for trend=0.0040) and adiponectin (p for trend=0.0097) 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=0.0198), 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.
