Latino Teens = Sexual Adventurers? It’s Complicated Says Researcher


A University of Illinois researcher advises caution when trying to characterize gender roles and sexual behavior among this country’s Latino adolescents and young adults.

“When a recent documentary about U.S. Latinos featured two teen mothers in a 90-minute program, the Latino students in my classes thought it was an unbalanced portrayal of their community—and they were right!” said Marcela Raffaelli, a U of I professor of human and community development and co-author of a recently published chapter on Latino teen sexuality.

Latino Adolescent Couple
National surveys do show that Latino young people as a group are less likely than their non-Latino peers to use condoms and birth control and are more likely to become pregnant and have a child. But these statistics hide a much more complicated picture, she said.

For one thing, Latinos represent more than 20 different groups, and they live in very different situations in the United States.

“For example, Cuban immigrants who moved to the United States when Castro came to power tended to be very wealthy, and they created an entrepreneurial, successful enclave in Miami. Compare them with Central American immigrants who may be refugees from a civil war in the 1980s. Language, religion, and some aspects of culture are apt to be the same, but socioeconomic status is probably very different, and that’s a big predictor of early sexual activity and teen pregnancy,” Raffaelli said.

When you adjust for socioeconomic status and other demographic factors, the difference in adolescent sexual behavior between Latinos and other groups largely disappears.

Attempts to understand sexuality among Latino teens are also complicated in that researchers don’t have the data to draw conclusions about how cultural factors influence sexuality. “People talk a lot about Latino culture and sexuality, but they typically don’t measure cultural variables, such as adherence to cultural norms and attitudes, in their studies,” she said.

So what do we know about Latino sexuality and risk taking among teenagers? For one thing, no one really knows how much the traditional gender role attributes of machismo and marianismo—idealizing the Virgin Mary—actually influence today’s Latino adolescents.

“In traditional Latin cultures, machismo dictates that men be virile and strong and provide for their family. In the United States, when we say macho, often we mean someone’s a male chauvinist, but in most Latin cultures, this idea encompasses such positive behavior as being responsible for your family and taking care of your household,” she said.

The female ideal of marianismo includes being self-sacrificing, pure, and silent. But the researcher emphasized that few studies have tried to measure the extent to which Latinos adhere to these traditional gender roles and whether cultural beliefs are linked to sexual behavior.

“Also, most research on Latino gender roles and sexuality doesn’t take into account that Latin cultures have changed tremendously over the last 20 years as a result of globalization, migration, and changing norms,” she added.

Immigrant status also plays a role in teens’ sexual risk taking. “For first-generation Latinos, recent immigration seems to be a protective factor. Families tend to bring the practices they had in their home country, and over time there’s a shift as they become acculturated. For girls, being an immigrant is protective because Latin American countries are typically more conservative about sexuality than the United States is,” she said.

For boys, the opposite pattern may be true because in many Latin American countries men have more freedom to explore their sexuality. In the United States, they might shift to a more conservative pattern, she said.

Scholars in multiple disciplines have described a pattern called the “immigrant paradox” in which immigrants have better outcomes than their U.S.-born counterparts despite their more challenging situations.

“First-generation teens do better in school, get into less trouble, have fewer early pregnancies, and so on, but by the second or third generation, that protective effect dissipates. A lot of immigrant families have tremendous optimism. They think, our life here is difficult, but we’re here to improve our children’s chances and, besides, things may be worse back home,” she said.

“By the third generation, things often look very different—maybe because of discrimination, bad schools, or socioeconomic factors,” she said.

Raffaelli said that she and other researchers are working to update what is known about American Latino families. “Cultural ideals provide general guidelines, but we need recent research to tell us whether people believe in these ideals and how much those beliefs affect behavior,” she said.

Raffaeli and co-author Maria I. Iturbide of the University of Nebraska at Lincoln wrote the chapter “Sexuality and Sexual Risk Behaviors Among Latino Adolescents and Young Adults” for the Handbook of U.S. Latino Psychology.

Stem Cells from Hair Follicles May Help “Grow” New Blood Vessels

muscle progenitor cellBUFFALO, N.Y. — For a rich source of stem cells to be engineered into new blood vessels or skin tissue, clinicians may one day look no further than the hair on their patients’ heads, according to new research published earlier this month by University at Buffalo engineers.

“Engineering blood vessels for bypass surgery, promoting the formation of new blood vessels or regenerating new skin tissue using stem cells obtained from the most accessible source — hair follicles — is a real possibility,” said Stelios T. Andreadis, Ph.D., co-author of the paper in Cardiovascular Research and associate professor in the Department of Chemical and Biological Engineering in the UB School of Engineering and Applied Sciences.

Researchers from other institutions previously had shown that hair follicles contain stem cells.

Major collaboration uncovers surprising new genetic clues to diabetes

Analysis identifies potential new therapeutic targets

An international team that included scientists from the National Human Genome Research Institute (NHGRI), part of the National Institutes of Health (NIH), today reported it has identified six more genetic variants involved in type 2 diabetes, boosting to 16 the total number of genetic risk factors associated with increased risk of the disease. None of the genetic variants uncovered by the new study had previously been suspected of playing a role in type 2 diabetes. Intriguingly, the new variant most strongly associated with type 2 diabetes also was recently implicated in a very different condition: prostate cancer.

The unprecedented analysis, published today in the advance online edition of Nature Genetics, combined genetic data from more than 70,000 people. The work was carried out through the collaborative efforts of more than 90 researchers at more than 40 centers in Europe and North America.

“None of the genes we have found was previously on the radar screen of diabetes researchers,” said one of the paper’s senior authors, Mark McCarthy, M.D., of the University of Oxford in England. “Each of these genes, therefore, provides new clues to the processes that go wrong when diabetes develops, and each provides an opportunity for the generation of new approaches for treating or preventing this condition.” Continue reading ‘Major collaboration uncovers surprising new genetic clues to diabetes’

Selenium supplements may increase the risk of type 2 diabetes

Selenium, an antioxidant included in multivitamin tablets thought to have a possible protective effect against the development of type 2 diabetes, may actually increase the risk of developing the disease, an analysis by researchers at the University at Buffalo has shown.

Results of a randomized clinical trial using 200 micrograms of selenium alone showed that 55 percent more cases of type 2 diabetes developed among participants randomized to receive selenium than in those who received a placebo pill.

Results will appear in print in the August 2007 issue of Annals of Internal Medicine and were posted online on July 10.

Self-reported diagnosis of type 2 diabetes was a secondary endpoint in a clinical trial designed to test the benefit of selenium supplementation in prevention of non-melanoma skin cancer in areas in the Eastern U.S. where selenium levels are lower than the national average. Selenium is a trace mineral that is an essential component of proteins involved in antioxidant activity. Continue reading ‘Selenium supplements may increase the risk of type 2 diabetes’

Women, Arthritis Sufferers have Poorer Short-Term Recovery from Arthroscopic Knee Surgery

New research by Yale medical student identifies different factors for optimal short- versus long-term recovery.

The factors associated with poor short-term recovery from knee surgery appear to be different than those found to mar long-term outcome from the same surgery, according to new research released today at the 2007 Annual Meeting of the American Orthopaedic Society for Sports Medicine at the Telus Convention Center (July 12-15).

“We found that women showed poorer short-term recovery than men in the first year following arthroscopic meniscal tear removal surgery, and people with osteoarthritis also did not do as well as others,” says principal investigator Peter Fabricant, BS, a medical student at Yale University School of Medicine in New Haven, Conn. “The factors associated with a poorer long-term outcome, such as larger tear size, greater amount of tissue removed, advanced patient age, and higher Body Mass Index, are not the same as those we can associate with short-term surgical recovery.” Continue reading ‘Women, Arthritis Sufferers have Poorer Short-Term Recovery from Arthroscopic Knee Surgery’

Jordin Sparks is Fat!

Don’t look at me. Some visual expert named Meme Roth has expressed her dismay at Jordin Sparks for not being a good role model because “apparently”, she’s not fat, but obese. Now this is some good TV, everything is going crazy at FOX News!

I’m pretty careful with the articles I write in this blog, citing sources whenever applicable. And I believe so should everybody else, especially professionals in the medical field. I didn’t see any MD attached to her name. Dietitian? Nutritionist, maybe? Her website mentions nothing but a cute slogan, “I am the picture and message of prevention…” Uh, if preventing me from getting fat is this eye-soring, sorry, ma’am, I’ll pass.

Sure, you don’t need to be an MS or have a PhD to call someone fat, as much as Rachel Ray needs no measuring cups, miraculously eyeballing all her fluid ingredients to concoct a fabulous 30-minute meal (not that I have anything against RR). However, this video clip is such a hair-pulling moment.

Three Rice Options for Diabetics

Sheik Md Jalal Uddin asks:

I am suffering from diabetes [sic].
Is rice ok for diabetes?
How do I measure it?

Thank you for asking, Sheik. You have at least three options to choose from. In my opinion, using the Glycemic Index (GI) is a simple tool to determine the type of rice that is best not only for people with diabetes, but also for individuals suffering from glucose intolerance, a symptom often overlooked that precedes a number of medical conditions including inflammatory diseases. To refresh your memory, GI measures how rapid carbohydrates affect the blood glucose (sugar) levels, within two hours of intake. Think of it as a ranking system for carbs; the lower the value, the lesser effect on glucose levels. If you have a very selective palate, may I recommend that you skip to the last choice, Basmati rice, otherwise, if you are after the best type for regulating glucose levels, not so much the taste, kindly continue to the Continue reading ‘Three Rice Options for Diabetics’

Red Wine Compound May Promote Youthfullness

Perhaps everybody will agree if I say everybody wants to stay young and beautiful. Well, pretty good guess I may say but that’s the truth. Everybody just hate aging and even seeing signs of it.

We resort to medications, treatment options and even cosmetics in order to combat and halt aging. Scientists today have identified a compound (resveratrol) that stimulates sirtuin a gene that promotes youthfullness, and inhibits the body’s predestination to aging and such compound is found in red wines and skins of grapes.

New York City On Transfats

Reading on the news today, it shows that New York City could be the first State to radically ban the use of transfats in cooking and other food preparation activities.

It was shown that the consumption of trans fat may contribute to clogging of the arteries which results to various types cardiovascular diseases leading to heart attack.

Transfats are created through the addition of hydrogen to a vegetable oil. This activity increases the possibility of producing more dangerous types of cholesterol that are hazardous to health.

The Benefits of Getting a Good Night Sleep

Perhaps sleeping at night may not be applicable for everyone due to varying work schedules, better yet, we would like to focus on the benefits of sleeping as a whole.

America may be one of the countries where sleeping is valued. The demands of everyday work and social commitments have taken toll on Americans’ sleeping habit. The following are just some of the reasons why getting the recommended hours of sleep has been hard to get.

• Work demands
• Shifting work schedules
• Existing sleeping problems
• Pathological Worrying, etc.
• Eating habits, etc.

While the above causes might not be the case for some people who are experiencing such condition, there will always be some people who will get susceptible to developing pathological sleeping problems.

The body can only endure much so following just simple recommendations below will put you out of this possible health danger.

• Follow regular sleeping patters, sleep and get up at the same time
of the night/day daily
• Do not do other stuff in bed other than sleeping and sex
• Eating lightly before sleeping will help you relax and fall asleep
• Keep room lighting at a level comfortable for sleeping (dim is
recommended)
