WASHINGTON, Jan. 25 (Xinhua) -- The odds of a major depressive episode are more than double for those working 11 or more hours a day compared to those working seven to eight hours a day, according to a report published Wednesday in the online journal PLoS ONE.The authors, led by Marianna Virtanen of the Finnish Institute of Occupational Health and University College London, followed about 2,000 middle aged British civil servants and found a robust association between overtime work and depression.This correlation was not affected when the analysis was adjusted for various possible confounders, including socio-demographics, lifestyle, and work-related factors.There have been a number of previous studies on the subject, with varying results, but the researchers emphasize that it is hard to compare results across these studies because the cut-off for "overtime" work has not been standardized."Although occasionally working overtime may have benefits for the individual and society, it is important to recognize that working excessive hours is also associated with an increased risk of major depression", Virtanen said in a statement.

China's Purchasing Managers Index (PMI), a preliminary readout of the country's manufacturing activity, rose to 50.5 percent in January of 2012, the highest level since October, indicating that a slowdown in the world's second-largest economy may be stabilizing.The country's PMI stood at 50.3 percent in December, 49 percent in November and 50.4 percent in October, the China Federation of Logistics and Purchasing (CFLP) said Wednesday in a statement on its website.A PMI reading of 50 percent demarcates expansion from contraction.The CFLP's sub-index for new orders hit 50.4 percent in January, up 0.6percentage points from December, suggesting that the week-long Spring Festival holiday helped boost the country's domestic consumption.The sub-index for purchase prices rose 2.9 percentage points from December to 50 percent in January.Last month, nine industries, including tobacco and beverage manufacturing, agricultural food processing and food production, enjoyed a PMI of over 50 percent, while sectors including wood processing and furniture manufacturing registered under 50 percent, according to the statement.The CFLP's PMI is based on a survey of purchasing managers in 820 companies in 20 industries.However, China plans to expand the sample size for measuring the PMI from the current 820 companies to around 3,000 companies, the National Bureau of Statistics and the CFLP said Tuesday at a news briefing, without giving a specific timetable for the changes.

The government will continue adopting measures to tame inflation this year, Zhou added, noting that efforts will be made to stabilize pig and vegetable production, further cut logistics costs, regulate the energy market to ensure supplies and subsidize low-income households.

For the study, 1,219 people older than age 65, free of dementia, provided information about their diet for an average of 1.2 years before their blood was tested for the beta-amyloid. Researchers looked specifically at 10 nutrients, including saturated fatty acids, omega-3 and omega-6 polyunsaturated fatty acids, mono- unsaturated fatty acid, vitamin E, vitamin C, beta-carotene, vitamin B12, folate and vitamin D.

"China welcomes the positive response from the Syrian government to Annan's proposal. At the same time, we urge the opposition to give a prompt and practical response to the peace plan, to create conditions for ending violence and initiating political dialogue," said a Chinese Foreign Ministry spokesman at a regular press briefing.
