- BACKGROUND: Subarachnoid haemorrhage (SAH) is a devastating disease, with high mortality rate and substantial disability among survivors. Its causes are poorly understood. We aimed to investigate risk factors for SAH using a novel nationwide cohort consortium.METHODS: We obtained individual participant data of 949 683 persons (330 334 women) between 25 and 90 years old, with no history of SAH at baseline, from 21 population-based cohorts. Outcomes were obtained from the Swedish Patient and Causes of Death Registries.RESULTS: During 13 704 959 person-years of follow-up, 2659 cases of first-ever fatal or non-fatal SAH occurred, with an age-standardized incidence rate of 9.0 [95% confidence interval (CI) (7.4-10.6)/100 000 person-years] in men and 13.8 [(11.4-16.2)/100 000 person-years] in women. The incidence rate increased exponentially with higher age. In multivariable-adjusted Poisson models, marked sex interactions for current smoking and body mass index (BMI) were observed. Current smoking conferred a rate ratio (RR) of 2.24 (95% CI 1.95-2.57) in women and 1.62 (1.47-1.79) in men. One standard deviation higher BMI was associated with an RR of 0.86 (0.81-0.92) in women and 1.02 (0.96-1.08) in men. Higher blood pressure and lower education level were also associated with higher risk of SAH.CONCLUSIONS: The risk of SAH is 45% higher in women than in men, with substantial sex differences in risk factor strengths. In particular, a markedly stronger adverse effect of smoking in women may motivate targeted public health initiatives.

- BACKGROUND: A neuroprotective effect of dietary antioxidants on Parkinson's disease (PD) risk has been suggested, but epidemiological evidence is limited.OBJECTIVES: To examine the associations between intake of dietary antioxidant vitamins and total antioxidant capacity and risk of PD.METHODS: We prospectively assessed the relationships of dietary antioxidant vitamins C and E, ß-carotene, and total antioxidant capacity with PD risk in two population-based cohorts (38,937 women and 45,837 men).RESULTS: During a mean 14.9-year follow-up period, 1,329 PD cases were identified. Dietary intake of ß-carotene was associated with a lower risk of PD (hazard ratio: 0.86; 95% confidence interval: 0.78-0.95; Ptrend < 0.01 for women and hazard ratio: 0.91; 95% confidence interval: 0.84-0.99; Ptrend = 0.05 for men). An inverse association between dietary vitamin E and PD risk was found in women (hazard ratio: 0.87; 95% confidence interval: 0.79-0.96; Ptrend = 0.02). Dietary intake of vitamin C was inversely associated with PD risk in women at borderline significance (hazard ratio: 0.91; 95% confidence interval: 0.83-1.00; Ptrend = 0.04). There was no association between dietary total antioxidant capacity and PD risk in either women (hazard ratio: 0.93; 95% confidence interval: 0.84-1.02; Ptrend = 0.35) or men (hazard ratio: 1.00; 95% confidence interval: 0.93-1.07; Ptrend = 0.97).CONCLUSION: Intake of dietary vitamin E and ß-carotene was associated with a lower risk of PD. © 2017 The Authors.
