Children in public housing play outdoors more

Study has implications for preventing obesity in kids

2011-02-18
(Press-News.org) Young children living in urban public housing spend more time playing outdoors than other urban children, according to researchers at Rice University, Columbia University and Princeton University.

Contrary to the expectations of the researchers, who hypothesized that children living in poorer circumstances would be playing outside less, the study found that 5-year-olds living in public housing played outside 13 percent more per day, on average, than did other urban 5-year-olds. Children living in places of high physical disorder -- areas with visible graffiti, trash, and abandoned homes -- also played outside more per day.

The researchers also concluded that the ratio of outdoor play to television watching is a significant predictor of body mass indexes (BMIs). The study, "Young Children in Urban Areas: Links Among Neighborhood Characteristics, Weight Status, Outdoor Play and Television-Watching," showed that for each additional hour the children played outside over the amount of time spent watching television, children scored 1.5 percentile points lower on BMI. BMI is a measure of body fat based on height and weight. The higher a person's BMI, the higher their risk for heart disease, high blood pressure, type 2 diabetes and other health problems.

"A key to solving obesity problems among poor, urban children is to create safe and open spaces where these kids can play, because now we know that they are outside playing," said Rachel Kimbro, assistant professor of sociology at Rice University and lead author of the new study. "It's possible that children living in public housing have access to community playgrounds and courtyards for children to play outdoors, which could be why we see more outside play time for them."

Kimbro and her co-authors -- Jeanne Brooks-Gunn of Columbia University and Sara McLanahan of Princeton University -- also found that a mother's perception of her neighborhood's physical and social environment was a key predictor of how much her children would play outdoors. They measured mothers' perceptions of collective efficacy by asking them questions that gauged how likely the mother thought that neighbors would intervene in certain situations (such as if a child were skipping school and hanging out on the street) and whether mothers thought their neighborhoods were cohesive (such as people's willingness to help their neighbors).

Children of mothers who perceived higher levels of collective efficacy in their neighborhoods played outside for longer periods each day, watched less television and visited the park or playground more often each week.

The researchers tested whether subjective and objective neighborhood measures -- socioeconomic status, type of dwelling, perceived collective efficacy and interviewer-assessed physical disorder of the immediate environment outside the home -- were associated with children's activities.

"Maternal perceptions of neighborhood environments, both positive and negative, truly override objective measures, such as neighborhood poverty status, when considering children's activities," Kimbro said. "Given the importance of maternal perception, it becomes critical to create community-based programs that seek to facilitate trust and neighborhood social networks in these low-income, urban areas."

The data, collected through the Fragile Families and Child Well-being Study, represent more than 1,800 5-year-olds in 2003-2004 in urban areas of the U.S. Overall, 19 percent of the sample was overweight (between the 85th and 95th percentiles) and 16 percent was obese (above the 95th percentile).

Shining a light on trypanosome reproduction

2011-02-18
The research could eventually lead to new approaches for controlling sleeping sickness in humans and wasting diseases in livestock which are caused by trypanosomes carried by the bloodsucking tsetse fly. Biologists believe that sexual reproduction evolved very early and is now ubiquitous in organisms with complex cell structure (the eukaryotes, essentially all living organisms except bacteria). However, real evidence is lacking for a large section of the evolutionary tree. Trypanosomes represent an early and very distant branch of the eukaryote tree of life and ...

Biomarker discovery may lead to reliable blood test for ectopic pregnancy

2011-02-18
Scientists at The Wistar Institute and the University of Pennsylvania School of Medicine report the discovery of protein markers that could provide physicians with the first reliable blood test to predict ectopic pregnancies. Their findings are presented in the February 16 issue of the Journal of Proteome Research, currently available online. In a related small-scale study of clinical samples, published recently in the journal Fertility and Sterility, the researchers found that one of the proteins—ADAM12—showed a nearly 97 percent correlation with ectopic pregnancy. Ectopic ...

Cigarette smoking increases production of mucus in patients with bronchitis

2011-02-18
Cigarette smoking has been linked with overproduction of mucus associated with chronic bronchitis, according to a study conducted by researchers in New Mexico. The study indicates cigarette smoke suppresses a protein that causes the natural death of mucus-producing cells in the airways of bronchitis patients. The findings were published online ahead of the print edition of the American Thoracic Society's American Journal of Respiratory and Critical Care Medicine. "Although it is known that chronic mucus secretion is a hallmark of chronic bronchitis, the mechanisms underlying ...

Everything you wanted to know about microbes and oil spills but were afraid to ask

2011-02-18
Is it true that microbes cleaned up the oil spill in the Gulf of Mexico? Can bacteria really "eat" oil, and if so, how? To help clear up the confusion the American Academy of Microbiology has brought together the nation's leading experts to consider and answer some of the most frequently asked questions regarding microbes and oil spills. "Long before the Gulf oil spill microbes evolved the ability to degrade the complex hydrocarbon mixture we call petroleum. They were already present in the Gulf of Mexico and ready to attack the oil when the spill occurred," says Ronald ...
