- Context Whether the psychological wellbeing status could be a risk factor for type 2 diabetes is unclear. Objective We aimed to measure the association between combined psychological wellbeing factors and type 2 diabetes and investigate whether this association was modified by genetic predisposition. Methods Prospective cohort study from the UK Biobank. In total, 127 496 participants who completed a psychological wellbeing questionnaire and did not have type 2 diabetes at baseline (2006-2010) were included; among them, 88 584 (69.5%) were analyzed to determine their genetic predisposition. The main outcome measure was incident type 2 diabetes. Results During the median follow-up of 10.0 years, 2547 incident type 2 diabetes cases were documented. Moderate to extreme unhappiness, satisfaction score <= 3, presence of broad depression, and a neuroticism score >= 3 were all significantly and independently associated with an increased risk of diabetes. When considered as a combination indicator, compared with individuals in the highest quartile of the psychological wellbeing score, the fully adjusted hazard ratios (95% CI) of type 2 diabetes were 1.41 (1.21-1.65) in the third quartile, 1.45 (1.24-1.69) in the second quartile, and 1.73 (1.48-2.01) in the lowest quartile. In the stratified analysis, we observed significant interactions between age and physical activity, and type 2 diabetes (P-interaction < .001 and 0.049, respectively). However, there was no significant interaction between the psychological wellbeing score and genetic susceptibility to diabetes (P-interaction = .980). Conclusion Worse overall psychological wellbeing was associated with a significantly increased risk of type 2 diabetes in a dose-response fashion regardless of genetic predisposition.

- Background and Aim Non-alcoholic fatty liver disease (NAFLD) is associated with incident type 2 diabetes; however, the extent to which NAFLD may confer its risk remains uncertain, especially in Europeans. Emerging evidence suggests that sleep behaviors are linked to NAFLD and diabetes. We aimed to measure whether sleep behaviors modified the association between NAFLD and incident type 2 diabetes. Methods This prospective cohort study included 365 339 participants without type 2 diabetes at baseline in UK Biobank data. Five sleep behaviors, including sleep duration, insomnia, snoring, chronotype, and daytime sleepiness, were collected from the questionnaire. Overall sleep patterns were created by summing the five scores. Liver steatosis was based on the fatty liver index. Results During a median follow up of 11.0 years, we documented 8774 patients with incident type 2 diabetes. NAFLD was significantly associated with increased diabetes risk. Sleeping 7-8 h/day, no insomnia, no self-reported snoring, and no frequent daytime sleepiness were independently associated with incident type 2 diabetes, with a 20%, 18%, 16%, and 31% lower risk, respectively. About 33.8% and 33.5% of type 2 diabetes events in this cohort could be attributed to NAFLD and poor sleep pattern, respectively. Participants with NAFLD and poor sleep pattern showed the highest risk of type 2 diabetes (relative risk 3.17, 95% confidence interval 2.80, 3.59). Sleep pattern (healthy, intermediate, and poor) did not significantly modify the association between NAFLD and type 2 diabetes. However, when studying separately, we found a significant interaction between NAFLD and insomnia on the risk of incident type 2 diabetes (P for interaction = 0.003). Conclusion In this large prospective study, both NAFLD and some sleep behaviors were risk factors for type 2 diabetes. Although overall sleep pattern did not modify the association between NAFLD and type 2 diabetes, certain sleep behavior, especially insomnia, showed the modification effect.
