Study: Liver Cancer in Latinos Linked to Diabetes, Obesity



Liver cancer rates among South Texas Latinos are higher than in other U.S. Latinos, as are their rates of obesity and diabetes—and the relationships between these ailments are being mapped by researchers at the Institute for Health Promotion Research (IHPR) at The UT Health Science Center at San Antonio, the team behind SaludToday. In a study published April 18, 2012, in the journal PLoS ONE, the researchers looked at overall liver cancer rates among U.S. Latinos and compared this to a Texas sample and a South Texas subset from 1995-2006. They also compared prevalence among Latinos of lifestyle-associated factors that contribute to liver cancer: heavy alcohol use, smoking, obesity and diabetes. They found that from 1995 to 2006, annual age-adjusted liver cancer incidence ...

Where to Locate Schools? What to Consider – and Why It Matters



Forty years ago, nearly half of all students walked or biked to school. Now, only 14 percent do. Why the change? One major factor is school siting, the decisions school leaders make about where to build or rehabilitate schools. Over the past several decades, schools have increasingly been built on the outskirts of communities, too far from children’s homes for walking or biking to be practical. Meanwhile, obesity rates in children and adolescents have more than tripled, and a third of children are overweight or obese. Locating schools closer to where families live can make it easier for kids to walk and bike to school—and more convenient for families to use school fields and other facilities after hours, when school is closed. When it comes to ethnicity and socioeconomic ...

New Guide Can Help Open School Property to the Public for Physical Activity



Nearly a third of U.S. kids and adolescents are overweight or obese, especially minority groups, including Latinos. Many are urged to get more exercise but can’t follow this advice very easily where they live. Schools, for instance, have many recreational facilities—gyms, soccer fields, tracks, basketball courts, playgrounds, even swimming pools—but they keep them closed after hours due to security, liability and maintenance concerns. But communities around the country are resolving these issues through what’s known as a joint use agreement: a written contract between a school district and, usually, a city agency, spelling out a formal arrangement that lets the two share the costs and maintenance and liability responsibilities. Playing Smart is a new nuts-and-bolts ...

Exposure to Recreation Center Increases Use by Latino Families with Children



Community recreation centers that develop culturally tailored programs that invite Latino families inside can increase sustained use of the center for physical activity in this population at heightened risk for childhood obesity, according to a new study in Childhood Obesity. Living near community recreation centers (CRC) is associated with increases in adolescent and adult physical activity. However, the efficacy of efforts to increase use among Latino parents and children is unknown. So researchers, led by Dr. Shari Barkin, a Vanderbilt University researcher and grantee of Salud America!, compared 66 Latino parent–child pairs who had participated in a culturally tailored healthy lifestyle program at a community recreation center and completed a 12-month follow-up ...
