WASHINGTON, May 25 (Xinhua) -- The number of young adults in the United States with high blood pressure may be much higher than previously reported, according to a new study by researchers at the University of North Carolina (UNC) at Chapel Hill.Researchers analyzed data on more than 14,000 men and women between 24 and 32 years old in 2008 from the National Longitudinal Study of Adolescent Health, known as Add Health. They found 19 percent had elevated blood pressure, also referred to as hypertension. Only about half of the participants with elevated blood pressure had ever been told by a health-care provider that they had the condition."The findings are significant because they indicate that many young adults are at risk of developing heart disease, but are unaware that they have hypertension," said Quynh Nguyen, a doctoral student at UNC's Gillings School of Global Public Health and the study's lead author. Hypertension is a strong risk factor for stroke and coronary heart disease, the leading cause of death for adults in the United States.The findings were published this week in the journal Epidemiology.Kathleen Mullan Harris, Add Health's principal investigator and a co-author of the paper, said the findings were noteworthy because they were from the first nationally representative, field- based study of blood pressure to focus on young adults."The message is clear," said Harris. "Young adults and the medical professionals they visit shouldn't assume they're not old enough to have high blood pressure. This is a condition that leads to chronic illness, premature death and costly medical treatment."

CANBERRA, May 26 (Xinhua) -- Australian Health Minister Nicola Roxon on Thursday night said she will not be frightened off by the tobacco industry's attempt to lobby Malaysia to oppose the Australian government's proposal for plain packaging of cigarettes.According to ABC News, big tobacco companies have appointed a former United States ambassador to the World Trade Organization ( WTO), Peter Allgeier, to help them fight the Australian federal government's plain packaging plan, which is due to come into effect this year.An email sent to a Malaysian official and obtained by ABC News showed that Allgeier had a meeting with Malaysia's trade minister before, and he has been lobbying a Malaysian administrator to put pressure on Australia over plain packaging.Allgeier's email also stated that "members of the U.S. congress also have written to the Australian Government outlining concerns about the implications of plain packaging for the integrity of Australia's trade commitments."However, Roxon, who said she has not been approached by Malaysia on the issue, said Allgeier's appointment demonstrated just how far big tobacco is prepared to take its fight."But we won't be frightened off because big tobacco is hiring lobbyists or looking at ways to influence the action we're taking, " she told ABC television on Thursday night.The tobacco industry has already spent millions fighting plain packaging, and last year gave 5.2 million U.S. dollars to the Alliance of Australian Retailers (AAR) to fund an advertising campaign against the plan.If the cigarettes law is enforced, Australia will become the first country in the world to ban logos and brand names from cigarette packaging. Health warnings and the kind of graphic pictures will make up the majority of the packaging, while the rest of the packets will be plain olive green.
