Dietary glycemic load, glycemic index, and carbohydrates on the risk of primary liver cancer among Chinese women and men
A partir des données des cohortes "Shanghai Women's Health Study" et "Shanghai Men's Health Study" incluant respectivement 72 966 femmes et 60 207 hommes, cette étude chinoise analyse l'association entre la charge glycémique, l'indice glycémique, l'ingestion de glucides et le risque de cancer du foie
Background Dietary glycemic index (GI) and glycemic load (GL) typically have a positive relationship with obesity and diabetes, which are risk factors for liver cancer. However, studies on their association with liver cancer have yielded inconsistent results. Therefore, we assessed the association of GI, GL, and carbohydrates with liver cancer risk.Patients and methods A total of 72 966 women and 60 207 men from the Shanghai Women's Health Study (SWHS) and the Shanghai Men's Health Study (SMHS) were included for analysis. Food frequency questionnaire (FFQ) data were used to calculate daily dietary GI, GL, and carbohydrate intake. These values were energy adjusted and categorized into quintiles. The hazard ratios (HRs) and 95% confidence intervals (CI) were calculated with adjustment for potential confounders.Results After a median follow-up time of 11.2 years for the SWHS and 5.3 years for the SMHS, 139 and 208 incident liver cancer cases were identified in the SWHS and SMHS, respectively. In multivariable Cox regression models, no statistically significant trends by quintile of GI, GL, or carbohydrate intake were observed. Stratification by chronic liver disease/hepatitis, diabetes, or body mass index (BMI) did not alter the findings.Conclusions There is little evidence that dietary GI, GL, or carbohydrates affect the incidence of liver cancer in this Asian population.
