- 요약Background: Evidence suggests that suboptimal birth weight may play a role in the development of colorectal cancer (CRC) later in life. Also, higher body mass index (BMI) has been linked to an increased risk of CRC. However, the impact of changes in body size over time on CRC risks remains uncertain. It is also unclear if adult body size influences the relationship between birth weight and the risk of CRC.Objectives: 1) To examine the body size trajectories during adulthood; 2) To investigate the associations between various adult body size measures and CRC risk; 3) To explore the association between birth weight and the risk of CRC; 4) To examine the potential mediation effects of adult body sizes on the association between birth weight and the risk of CRC.Methods: The growth mixture model was used to model trajectories of BMI. Cox proportional hazards regression was used to estimate the hazard ratios (HR) and corresponding 95% confidence interval (CI) of age-specific BMI, BMI trajectories, waist circumference, adult weight gain from age 18 to 50, as well as birth weight on the risk of CRC. Multiple mediation analyses were used to evaluate whether the association between birth weight and the CRC risk was mediated by adult body size.Results: Women who progressed from normal to obesity (HR 1.29, 95%CI 1.09-1.53) and women who remained overweight/obesity (HR 1.37, 95%CI 1.13-1.68) had higher CRC risks. A weight gain 15 kg from age 18 to 50 (HR 1.20, 95%CI 1.04-1.40) and baseline waist circumference 88 cm (HR 1.33, 95%CI 1.19-1.49) were associated with higher CRC risks. Compared with birth weights of 6- 8 lbs, birth weight ≥ 8 lbs was associated with higher CRC risk in postmenopausal women (HR = 1.31, 95%CI 1.16-1.48). The joint effect of adult height and weight explained 21.6 % of this positive association.Conclusion: Our study highlights the importance of maintaining a healthy body size over the life course. Our findings also suggested that the intrauterine environment and fetal development may play a role in the risk of developing CRC later in life.
