Experts Say Slant Toward Male Births Among Asian-American Families Reflects Sex Selection Practices
Research indicating distorted ratios of male to female births among U.S. residents of Chinese, Indian and Korean descent could reflect those families" openness to sex-selection techniques, according to some demographers, the New York Times reports. Historically, male births in the U.S. have led female births by a ratio of 1.05 to 1. A study published last year in Proceedings of the National Academy of Sciences examined 2000 census data and found that among Chinese-, Indian- and Korean-American families, if the first child was a girl, the likelihood that the second child was a boy increased to 1.17 to 1. In addition, if the first two children were girls, the chance that the third was a boy was 1.51 to 1, or about 50% greater than normal. In a study published this year, Jason Abrevaya of the University of Texas examined census data and birth records through 2004, finding that the incidence of boys as third children among immigrant Chinese parents in New York was 558 of every 1,000 births, significantly higher than the national average of 515. Many experts were surprised at the evidence that the cultural preference for sons among some Asian cultures has carried over to immigrants in the U.S., the Times reports. Studies have not demonstrated a slanted proportion of male births among Japanese immigrants, according to the Times. According to demography experts, the deviation toward male births among some Asian-American immigrants reflects both a cultural preference for boys and an increased tendency for families to seek out sex-selection techniques such as in vitro fertilization, sperm sorting or abortion. Some clinics that offer IVF or sperm sorting to select for sex market their services to Asian-American families through advertisements in Indian- and Chinese-language newspapers. In 2001, criticism arose within the Indian-American community about clinics targeting that population, and some community newspapers and magazines expressed regret for publishing advertisements that critics said were perpetuating a misogynistic practice. Joyce Moy, executive director of the Asian American/Asian Research Institute of the City University of New York, said that younger Chinese immigrants have adopted the family values that are common in China -- such as the tradition of elders depending on their sons for support -- even though some of the reasons behind those customs are less relevant in the U.S. Experts say that the preference for male children may fade with further assimilation, the Times reports.In China, sex selection typically is achieved through abortion of female fetuses. Although doctors say the practice also occurs in the U.S., few families discuss it, the Times reports. Lisa Eng, a Hong Kong-born gynecologist who practices in New York City"s Chinatown and Brooklyn, said that she attempts to discourage couples who prefer boys from having abortions. "If it"s going to be a third [child], they"re pretty determined to have a boy," she said, adding, "If it"s a boy, they keep it. If it"s a girl, they"ll abort" (Roberts, New York Times, 6/15).

New Study Shows Nexium 40 Mg And 20 Mg Reduced Gastric And Duodenal Ulcers By 80 - 85% In Patients Taking Low-Dose Aspirin For CV Protection
Esomeprazole significantly reduced the occurrence of gastric and duodenal ulcers and upper gastrointestinal (GI) symptoms in patients taking low-dose aspirin for risk reduction of adverse cardiovascular (CV) events[i], such as myocardial infarction (MI) and ischaemic stroke, according to new data presented today at the Digestive Diseases Week annual meeting (DDW, 30thMay - 4th June, Chicago).

University Of Minnesota Research Finds Teens Who Believe They'll Die Young Are More Likely To Engage In Risky Behavior

University of Minnesota Medical School researcher Iris Borowsky, M.D., Ph.D., and colleagues found that one in seven adolescents believe that it is highly likely that they will die before age 35, and this belief predicted that the adolescents" would engage in risky behaviors. Borowsky and colleagues analyzed data collected by the National Longitudinal Study of Adolescent Health, a nationally representative sample of more than 20,000 youth in grades 7 through 12 during three separate study years. In the first set of interviews, nearly 15 percent of adolescents predicted they had a 50/50 chance or less of living to age 35. Those who engaged in risky behaviors such as illicit drug use, suicide attempts, fighting, or unsafe sexual activity in the first year were more likely in subsequent years to believe they would die at a young age. Vice versa, those who predicted that they"d die young during the first interview were more likely in later years to begin engaging in these same risky behaviors and have poor health outcomes. Notably, these teens were significantly more likely to be diagnosed with HIV/AIDS just six years later, regardless of their sexual preference. "While conventional wisdom says that teens engage in risky behaviors because they feel invulnerable to harm, this study suggests that in some cases, teens take risks because they overestimate their vulnerability, specifically their risk of dying," Borowsky said. "These youth may take risks because they feel hopeless and figure that not much is at stake." Nearly 25 percent of youth living in households that receive public assistance and more than 29 percent of American-Indian, 26 percent of African-American, 21 percent of Hispanic, and 15 percent of Asian youth reported believing they would die young - compared to just 10 percent of their Caucasian peers. "Our findings reinforce the importance of instilling a sense of hope and optimism in youth," Borowsky said. "Strong connections with parents, families, and schools, as well as positive media messages, are likely important factors in developing an optimistic outlook for young people." She also notes that study findings support physician screening of adolescents for this perceived risk of early death. "This unusually common pessimistic view of the future is a powerful marker for high-risk status and thus deserves attention." There was no significant relationship between perceived risk of dying before age 35 and actual death from all causes during the six year study period. The study "Health Status and Behavioral Outcomes for Youth Who Anticipate a High Likelihood of Early Death," will be published in the July issue of Pediatrics. The study was funded by a grant from the National Institute of Child Health and Human Development, with cooperative funding from 17 other agencies. Laura Stroup University of Minnesota
