Toddlers from low-income Hispanic, American Indian (AI), and Alaskan Native (AN) homes are at increased risk for obesity, according to a new study, Medscape reports.
The federal study, published in the journal Pediatrics, collected weight data for 1.2 million children at ages 0 to 23 months in 2008 and followed up with them within 24 to 35 months in 2010-11. In 2008, 13.3% of children were obese. In 2010-11, 36.5% of those children remained obese and 11% who were not obese at baseline became obese at follow-up.
The Medscape article also highlighted some striking disparities in children’s weight by race/ethnicity:
At baseline, obesity rates were higher among Hispanic and AI/AN toddlers, with 18.0% of AI/AN children obese at baseline compared with 15.3% of Hispanic children, 12.8% of non-Hispanic black children, 11.5% of white children, and 9.5 of Asian/Pacific Island children. In addition, Hispanic and AI/AN children were more likely to remain obese at follow-up at 40.3% and 44.4%,respectively, compared with 34.7% of whites, 33.2% of Asian/Pacific islanders, and 30.5% of non-Hispanic blacks.
AI/AN and Hispanic youngsters were more likely to become obese 24 to 35 months after initial examination. Some 15.4% of AI/AM children became obese at follow-up. Of Hispanic children, 13.6% became obese compared with 9.7% of white children, 9.0% of Asian/Pacific Island children, and 8.7% of black children.
“The needs of Hispanic and AI/AN young children should be considered when designing population-based strategies to support environmental and system change in communities and culturally appropriate interventions,” the the researchers stated in the study’s conclusion.
A new study is testing whether an automated self-help “Stop Smoking” website—available in both English and Spanish with various resources and tools to track quit progress—can help smokers quit at higher rates than trying to quit on their own.
The study, led by Redes En Acción: The National Latino Cancer Research Network, which is funded by the National Cancer Institute, is a collaboration between researchers at the Institute for Health Promotion Research (IHPR) at The UT Health Science Center at San Antonio and the University of California, San Francisco (UCSF).
Upon enrollment, researchers will randomly assign participants to one of two methods to quit:
- Immediate no-cost access to the UCSF “Stop Smoking” website
- “Quit on Your Own” plus no-cost access to the same website after 6 months
Participants’ smoking status will be evaluated at 1, 3, and 6 months.
Latinas tend to have positive attitudes and strong interest in genetic testing for breast cancer risk, yet lacked general knowledge about testing, its risks and benefits, according to a new study led by researchers at the Institute for Health Promotion Research (IHPR) at the UT Health Science Center at San Antonio, the team behind SaludToday.
The study, published recently in the journal Community Medicine & Health Education, conducted focus groups with 58 Latinas in Hidalgo County, a largely Latino part of South Texas.
Researchers used analyzed focus group responses and themes and uncovered several cultural factors, such as religious beliefs, that impacted Latinas’ decisions to get genetic testing.
“Key Latino values—religiosity, importance of family and the influential role of health care providers in health decisions—should be considered when designing strategies to deliver culturally adapted risk information to increase and ensure Latinas’ understanding of breast cancer genetic testing during their decision-making processes,” said Dr. Amelie G. Ramirez, the study’s corresponding author and director of the IHPR at the Health Science Center.
Genetic testing for breast cancer risk may facilitate better-informed decisions regarding cancer prevention, risk reduction, early detection, and better determination of risk for family members.
However, among women who are tested, less than 4% are Latina.
Finding reasons for Latinas’ low participation was the goal of Dr. Ramirez and her team, which included IHPR researchers Dr. Patricia Chalela and Edgar Muñoz and investigators from the University of North Texas Health Science Center and the University of Texas-Pan American.
The researchers found that none of the focus group participants had ever had a genetic test, and most didn’t know what the test was or how it is done.
Most women, after learning what a genetic test was, indicated they would get a genetic test in the next six months if it were available—at no or low cost—to be able to prevent cancer through healthy lifestyle changes or act as soon as possible to treat disease.
But among some of lesser-educated focus group participants, lack of accurate information about testing and cultural beliefs may hinder their use of genetic testing for breast cancer.
For example, some Latina participants viewed God as the only one who can cure cancer, which might impact their preventive health behaviors. And given Latinos’ tendency to trust the advice of health care providers, some Latinas who lacked health insurance or access to a regular doctor may have fewer opportunities to learn about genetic testing.
“Further research is needed to identify effective ways to communicate genetic risk susceptibility information to Latinas to help them make informed testing decisions,” Ramirez said.

The study, published recently in Public Health Nutrition, compared the availability, quality and cost of healthy and unhealthy foods in 10 tiendas and 15 supermarkets in San Diego County, Calif.
Researchers found that tiendas were smaller, charged more for a gallon of skim milk, and offered less lean ground beef than supermarkets.
However, they also found that tiendas had similar fresh produce offerings at lower prices.
“These results highlight the potential that tiendas have in improving access to quality, fresh produce within lower-income communities,” the researchers concluded. “However, efforts are needed to increase the access and affordability of healthy dairy and meat products.”
To find out, the Institute for Health Promotion Research (IHPR) at the UT Health Science Center at San Antonio is enrolling Hispanic survivors of breast cancer for a 16-week clinical research exercise study conducted in South Texas’ Lower Rio Grande Valley to address this topic.
Changed thinking that leads to self-confidence leads to changed behavior—that’s the idea behind the study.
The study requires two visits to the UT Health Science Center at San Antonio’s Regional Academic Health Center campus in Harlingen to answer questionnaires, do a complete physical fitness assessment and develop each woman’s individualized comprehensive exercise program. Also, based on the answers, each woman receives a personalized newsletter geared just for her.
“The goal is to motivate the Hispanic women to increase their physical activity, as studies have shown this improves quality of life and reduces the risk of developing other cancers and diseases,” said Gabriela Villanueva, research area specialist associate with the IHPR, who is working on the National Cancer Institute-funded study led by the IHPR’s Dr. Daniel Carlos Hughes. “It’s a really good program for our women.”
Hispanic women 18 and older who completed their cancer treatment at least two months prior are invited to inquire about eligibility. Several Hispanic women have joined the study since it began early this year, but researchers are looking for more.
Study participants will be compensated up to $75 in gift cards for participating.
But perhaps the best part is they get a prescription of exercise that they can carry on long after the study has ended.

Diabetes, a disease that is expected to affect 9.9% of the world’s adult by 2030, takes an especially heavy toll on U.S. Hispanics, according to the Centers for Disease Control and Prevention (CDC), the Huffington Post reports.
Hispanics have double the risk of developing diabetes compared with non-Hispanic whites, according to a CDC a study on diabetes prevalence among Hispanics in California, Florida, Illinois, New York/New Jersey, Texas, and Puerto Rico from 1998 to 2002.
The CDC study also found that:
- Hispanics tend to develop diabetes at a younger age
- The prevalence of diabetes decreased with higher education levels; among Hispanics with less than a high school education, 11.8% had diabetes, compared to 7% of college graduates

Breast cancer survivors are invited to join a San Antonio-area study that is testing how different types of exercise—like yoga—best improve cancer survivors’ fitness and quality of life and decreases the risk of recurrence.
The project, Improving Mind and Physical ACTivity (IMPACT), is led by the Institute for Health Promotion Research (IHPR) at the UT Health Science Center at San Antonio.
Over the yearlong IMPACT study, 90 breast cancer survivors will be randomized to participate at least three times a week in: 1) a comprehensive exercise “prescription” featuring an individualized aerobic, strength-training and flexibility program; 2) a yoga exercise program; or 3) general exercise chosen at will.
Study recruitment is underway. For eligibility, call 210-593-2669.
“We expect comprehensive and yoga-focused participants to have better fitness outcomes, less stress and improved biological indicators of future risk of secondary cancers,” said study co-principal investigator Dr. Daniel Hughes of the IHPR. The study, funded by Susan G. Komen for the Cure, is led by IHPR Director Dr. Amelie Ramirez and features Cancer Therapy and Research Center (CTRC) translational scientists.
Participants in all three groups will take a fitness test and undergo measurements at the start and end of the study, and also fill out surveys and exercise logs.
Depression, in addition to other barriers, may prevent Latina breast cancer survivors from undergoing preventive health screening for colorectal and ovarian cancer, according to a new study.
The study was presented by Dr. Amelie G. Ramirez, professor and director of the Institute for Health Promotion Research at the UT Health Science Center at San Antonio, on Sept. 19, 2011, at the Fourth AACR Conference on The Science of Cancer Health Disparities in Washington D.C.
“Depression can make people more inattentive to potential risks to their health and more likely to ignore recommendations to reduce their risk,” Dr. Ramirez said.
Because depression is more common among breast cancer patients than the general population and because 10% of all new cancers are diagnosed in cancer survivors, Ramirez and colleagues examined the extent of depression among a group of 117 Latina breast cancer survivors to assess the barriers that were thwarting preventive health screening for colorectal and ovarian cancer.
All of the outcomes were self-reported and all patients were screened for depression.
“The most important thing that we found was that Hispanic breast cancer survivors were more depressed than Hispanics in the general population, and that they were not following recommendations to continue their other cancer screening behaviors,” Dr. Ramirez said.
Of the women who were surveyed, about one-third met the criteria for depression. Only five had been screened for both colorectal and ovarian cancers and about 60% had not been screened for one cancer or the other.
Ramirez said that a broad-based preventive strategy is needed to increase screening and healthy behaviors among this population.
“Regardless of depression or not, we need to work with these women to help them understand that they need to get more involved with their health care,” she said. “We also have to get a better handle on the underpinnings of depression among cancer survivors.”
