Objective  To evaluate the relationship between frequency of pruritic symptoms experienced over a 1-month period and psychological stress.

Design  Cohort study.

Setting  Population-based study in Japan.

Participants  A total of 2224 participants at least 18 years old and without psychiatric disorders participated in the Japan Health Diary Study (October 2003), a cohort study comprising a representative sample in Japan.

Main Outcome Measures  Frequency of pruritic symptoms assessed by self-reported health diaries over the 1-month period and subsequent psychological stress measured using the Japanese version of the Perceived Stress Scale.

Results  The 2224 participants had a mean age of 44.6 years, 1212 (54.5%) were women, and 70 (3.1%) presented with pruritic symptoms. Multivariable analysis showed that patients with pruritic symptoms had significantly higher psychological stress than those without pruritic symptoms (β coefficient, 2.33; 95% confidence interval [CI], 0.53-4.14; P = .01). Furthermore, a linear trend was observed between increased psychological stress and increased severity of pruritic symptoms, with β coefficients for the first, second, and third tertiles for symptoms of 0.81 (95% CI, –1.97 to 3.59), 1.77 (95% CI, –0.82 to 4.37), and 4.86 (95% CI, 1.29 to 8.43), respectively (P value for trend, .004).

Conclusion  Our results suggest that frequency of pruritic symptoms is associated with psychological stress in the general population.

  Aims  Whether health-related quality of life (HRQoL) can be accurately predicted in patients with extremely low HRQoL as a result of diabetic complications is unclear. We investigated the impact of HRQoL on mortality risk in patients with diabetes on haemodialysis.

Methods  Data from the Dialysis Outcomes Practice Pattern Study (DOPPS) were analysed for randomly selected patients receiving haemodialysis in Japan. Information regarding the diagnosis of diabetes and clinical events during follow-up was abstracted from the medical records at baseline and HRQoL was assessed by a self-reported short form (SF)-36 questionnaire. The association between physical component score and mental component score in the SF-36 and mortality risk was analysed using a Cox proportional hazard model.

Results  Data from 527 patients with diabetes on haemodialysis were analysed. The mortality age-adjusted hazard ratio of having a physical component score greater than or equal to the median was 0.27 [95% confidence interval (CI) 0.080.96] and the multivariable-adjusted mortality hazard ratio of having an mental component score greater than or equal to the median was 1.21 (95% CI 0.443.35).

Conclusions  The physical component score derived from the SF-36 is an independent risk factor for mortality in patients with diabetes on haemodialysis who generally had very low HRQoL scores. Baseline mental component score was not predictive of mortality. Patient self-reporting regarding the physical component of health status may aid in risk stratification and clinical decision making for patients with diabetes on haemodialysis.

  Aims  Acute administration of oolong tea decreases blood glucose levels. We investigated the association between long-term oolong tea intake and subsequent risk of developing diabetes among men of working age.

Methods  Data were analysed from a cohort of participants in the High-risk and Population Strategy for Occupational Health Promotion Study (HIPOP-OHP), conducted in Japan from 1999 to 2004. Oolong tea intake at baseline and subsequent risk of diabetes was evaluated using a Cox proportional hazards model.

Results  Of 4975 male workers, a total of 201 cases of diabetes were reported over a median of 3.4 years of follow-up. Mean age and BMI of all participants at baseline were 38.3 years and 22.9 kg/m2, respectively. Compared with those not consuming oolong tea, multivariable adjusted hazard ratios for developing diabetes were 1.00 (95% CI 0.67-1.49) for those who drank one cup of oolong tea per day and 1.64 (95% CI 1.11-2.40) for those drinking two or more cups per day. Fasting blood glucose increment per year was 0.11 mmol/l (95% CI 0.09-0.12 mmol/l), 0.12 mmol/l (95% CI 0.09-0.15 mmol/l) and 0.15 mmol/l (95% CI 0.11-0.18 mmol/l), respectively, for oolong tea consumption of 0, 1 and ≥ 2 cups/day, with a significant linear trend (P < 0.0001).

Conclusions  Long-term consumption of oolong tea may be a predictive factor for new onset diabetes. Further studies are necessary to elucidate the role of oolong tea in the risk of developing diabetes.
