Bisphenol A and other environmental risk factors for prostate cancer in Hong Kong.

Background: Environmental exposures are contributing factors to prostate cancer etiology, but these remain unclear. We aimed to document the associations between environmental risk factors and prostate cancer in Chinese, with special reference to bisphenol A (BPA).

Methods: We recruited 431 newly diagnosed prostate cancer cases and 402 age-matched controls from Prince of Wales Hospital in Hong Kong.

Prevention of anxiety and depression in Chinese: a randomized clinical trial testing the effectiveness of a stepped care program in primary care.

Background: Despite empirical evidence demonstrating the effectiveness of collaborative stepped care program (SCP) in Western countries, such programs have not been evaluated in the east, which has a different services system structure and cultural nuances in seeking help for mental illness. Furthermore, only a few studies have used SCP for depression and anxiety prevention. We conducted a trial to test its effectiveness in preventing major depressive disorder and generalized anxiety disorder among primary care patients with subthreshold depression and/or anxiety in Hong Kong.
