BEIJING, Feb. 12 (Xinhua) -- The Chinese government has reiterated a strict ban on hepatitis B tests during pre-employment physical examinations as many companies reportedly violated rules to require hepatitis B tests for job applicants.In a statement released Saturday, the Ministry of Health said that no health institutions are allowed to provide hepatitis B checks as part of pre-employment physical tests regardless of whether the examinees provide consent or not.On Feb. 10, 2010, the Ministry of Health, the Ministry of Education and the Ministry of Human Resources and Social Security jointly issued a circular demanding the cancellation of the hepatitis B tests during the health checks for school enrollment and employment nationwide.However, according to a survey released this week, which was conducted by the non-profit Beijing Yirenping Center, some 61.1 percent of the 180 state-run companies surveyed included hepatitis B checks in their pre-employment physical examinations.More surprisingly, 63 companies said that they would never consider hepatitis B carriers for a job or were reluctant to hire such people.Yu Fangqiang, the principal of the Yirenping Center, said that such violations mainly resulted from light punishment for violations and some health institutions' desire for profits.According to the survey, employers would only be fined between thousands to tens of thousands of yuan if they lose their lawsuits for bias against hepatitis B carriers.Meanwhile, a worker will spend a lot of time, energy and money to file a lawsuit and collect evidence in order to win.Liu Xiaonan, an associate professor with the China University of Political Science and Law, called on the government to hammer out a particular law and set up a special committee to investigate discrimination cases in order to ensure the rights of workers.In the statement released Saturday, the health ministry also ordered a careful investigation of all cases of hepatitis B discrimination, and promised that violators would be exposed and punished in accordance with laws and regulations.Medical tests show that hepatitis B virus can only be transmitted from mother to child during childbirth or by contact with the blood or other body fluids of an infected person.

LOS ANGELES, May 9 (Xinhua) -- Drinking alcohol may raise the likelihood among teenagers to spend more time on computers, a new study suggests.The study, conducted by researchers at Weill Cornell Medical College, was based on a survey of 264 teenagers, aged 13 to 17.Results showed that compared with teens who did not report drinking, those who drank alcohol in the last month used a computer more hours per week for non-school-related activities, including the use of social networking sites.Drinking was also linked to more frequent social networking and listening to and downloading music, according to the study published Monday in the on-line edition of the journal Addictive Behaviors.However, there was no demonstrated link between alcohol use and computer use for school work, neither there was strong link between video games and drinking or on-line shopping and drinking."While the specific factors linking teenage drinking and computer use are not yet established, it seems likely that adolescents are experimenting with drinking and activities on the Internet," said Dr. Epstein, assistant professor of public health at the college."In turn, exposure to on-line material such as alcohol advertising or alcohol-using peers on social networking sites could reinforce teens' drinking."Children are being exposed to computers and the Internet at younger ages. For this reason it's important that parents are actively involved in monitoring their children's computer usage, as well as alcohol use."Teenagers typically first experiment with alcohol at age 12 or 13, according to the study.Family risk factors include lax parental supervision and poor communication, family conflicts, inconsistent or harsh discipline and a family history of alcohol or drug abuse."According to a national study conducted by the Pew Internet and American Life Project, more than half of parents of teenagers had filters installed on the computers their child uses to block content parents find objectionable, yet many parents do not use any form of parental monitoring, particularly for older teens," Epstein said.

LOS ANGELES, April 14 (Xinhua) -- Vegetarians experience a much lower risk of metabolic syndrome than non-vegetarians, U.S. researchers have found.Researchers at Loma Linda University in California based their findings on analysis of more than 700 adults randomly sampled from a long-term study of the lifestyle and health of almost 100,000 Seventh-day Adventist Christians across the United States and Canada.While 25 percent of vegetarians had metabolic syndrome, the number significantly rises to 37 percent for semi-vegetarians and 39 percent for non-vegetarians, according to the study published in the April issue of the journal Diabetes Care.The findings showed that the risk of developing metabolic syndrome is 36 percent lower among vegetarians than non- vegetarians.This means that vegetarians are less likely to develop heart disease, diabetes and stroke -- three major conditions that are closely linked with metabolic syndrome, the researchers say.The study also found that vegetarians, though slightly older than non-vegetarians, had lower triglycerides, glucose levels, blood pressure, waist circumference, and body mass index (BMI). Semi-vegetarians, meanwhile, also had a significantly lower BMI and waist circumference compared to those who ate meat more regularly.The findings will not be affected by other factors such as age, gender, race, physical activity, calories consumed, smoking, and alcohol intake, the researchers say."In view of the high rate of metabolic syndrome in the United States and its deleterious health effects, we wanted to examine lifestyle patterns that could be effective in the prevention and possible treatment of this disorder," says lead researcher Nico S. Rizzo, PhD."I was not sure if there would be a significant difference between vegetarians and non-vegetarians, and I was surprised by just how much the numbers contrast," he says. "It indicates that lifestyle factors such as diet can be important in the prevention of metabolic syndrome."

BEIJING, Feb. 13 (Xinhua) -- Chinese State Councilor Meng Jianzhu left here Sunday for visits to the Democratic People's Republic of Korea (DPRK), Laos, Singapore and Malaysia.Meng, who is also Chinese Minister of Public Security, is traveling to the countries at the invitation of the DPRK Minister of People's Security Ju Sang Song, Lao Minister of Public Security Thongbanh Seng-aphone, Singaporean Minister for Home Affairs and Minister of Law K Shanmugam, and Malaysian Minister of Home Affairs Hishiammuddin Tun Hussein.

LOS ANGELES, March 2 (Xinhua) -- Those who take a nap are more likely to have lower levels of blood pressure despite stress, said a new study in the latest issue of International Journal of Behavioral Medicine available on Wednesday.In the study, researchers at Sarah Conklin of Allegheny College in Meadville, Pennsylvania examined 85 healthy university students, who were divided into two groups, with one group taking an hour- long nap during the day, and the other group having no time to sleep. Both groups were given a mental stress test.The study found that participants in both groups experienced increase in blood pressure and pulse rates when they took the stress test, but the average blood pressure of those who slept for at least 45 minutes was significantly lower after the stress test than it was for those who did not sleep.The researchers drew the conclusion that a daytime nap of at least 45 minutes may help stressed-out people lower their blood pressure and protect their heart."Our findings suggest that daytime sleep may offer cardiovascular benefit by accelerating cardiovascular recovery following mental stressors," the researchers said in the study."Further research is needed to explore the mechanism by which daytime sleep is linked with cardiovascular health and to evaluate daytime sleep as a recuperative and protective practice, especially for individuals with known cardiovascular disease risk and those with suboptimal sleep quality," they added.Sleep deficiency is common in the United States, posing a long- term health threat. On average, Americans get nearly two hours less sleep a night than they did 50 years ago, according to background information provided by the journal.
