Association between carbohydrate intake and the risk of psoriasis: a prospective cohort study based on UK Biobank.
Background: Research on the association between carbohydrate intake and psoriasis risk is limited. We aimed to examine the associations of carbohydrate and its different subtypes with psoriasis risk, as well as the interaction between genetic predisposition and carbohydrate intake.
Methods: We performed a prospective cohort study based on UK Biobank that included 210,474 participants who did not have psoriasis at baseline. A 24-hour dietary assessment tool was used to assess detailed dietary intake information. Incident psoriasis events were identified through hospitalization records. The association between carbohydrate intake and psoriasis was examined by Cox proportional hazard regression models. Multiplicative interaction between genetic risk and carbohydrate intake was assessed by incorporating a cross-product term in the model.
Results: A total of 1907 incident psoriasis events were recorded during the follow-up period (median: 13.25 years). Compared to the lowest intake quartile (Q1), the highest intake quartile (Q4) of total sugars [HR (95% CI) = 1.14 (1.01-1.29), FDR-Ptrend = 0.116], free sugars [1.22 (1.07-1.38), 0.021], and sucrose [1.14 (1.01-1.30), 0.058] was associated with an increased psoriasis risk. In contrast, the highest intake of starch [0.86 (0.76-0.98), 0.049] and fiber [0.84 (0.74-0.96), 0.021] showed an inverse association with psoriasis risk. However, there was no statistically significant interaction between carbohydrate intake and genetic risk.
Conclusion: Intake of total sugars, free sugar, and sucrose was positively associated with psoriasis risk, while fiber and starch were inversely associated.
期刊介绍：
Nutrition Journal publishes surveillance, epidemiologic, and intervention research that sheds light on i) influences (e.g., familial, environmental) on eating patterns; ii) associations between eating patterns and health, and iii) strategies to improve eating patterns among populations. The journal also welcomes manuscripts reporting on the psychometric properties (e.g., validity, reliability) and feasibility of methods (e.g., for assessing dietary intake) for human nutrition research. In addition, study protocols for controlled trials and cohort studies, with an emphasis on methods for assessing dietary exposures and outcomes as well as intervention components, will be considered.
Manuscripts that consider eating patterns holistically, as opposed to solely reductionist approaches that focus on specific dietary components in isolation, are encouraged. Also encouraged are papers that take a holistic or systems perspective in attempting to understand possible compensatory and differential effects of nutrition interventions. The journal does not consider animal studies.
In addition to the influence of eating patterns for human health, we also invite research providing insights into the environmental sustainability of dietary practices. Again, a holistic perspective is encouraged, for example, through the consideration of how eating patterns might maximize both human and planetary health.
