Docs more likely to suspect abuse in poor kids


1
NEW YORK (Reuters Health) - When a toddler has a broken bone, pediatricians may be more likely to suspect abuse if the family is lower-income, a new study finds.
Researchers found that pediatricians who read a fictional case report of a toddler with a leg fracture were more likely to suspect abuse if the child was described as coming from a lower-income family.
The hypothetical child's race, on the other hand, did not appear to influence doctors' opinions.
The second finding is somewhat surprising, according to the researchers. Studies looking at real-world cases have found that minority children are more likely to be evaluated for abuse than white children are.
And it's well known that the child welfare system in the U.S. has a disproportionate number of minority kids.
"There's very strong evidence of a racial difference in how patients are handled," said lead researcher Dr. Antoinette L. Laskey, a pediatrician at the Indiana University School of Medicine in Indianapolis.
But, she told Reuters Health, the reasons for that have not been clear -- including whether doctors may act based on unconscious racial stereotypes.
The current results suggest "there's more than race involved," Laskey said.
She was also quick to say, however, that the study doesn't mean pediatricians are consciously "classist" or otherwise biased when evaluating children's injuries.
The study, reported in the Journal of Pediatrics, included 2,100 U.S. pediatricians who responded to a survey that described one of four hypothetical cases.
All cases included an 18-month-old with an "ambiguous" leg fracture -- a type that can be caused by abuse or an accident.
But the cases varied by the child's race (black or white) and the family's economic situation; parents were described as having either professional jobs (accountant and bank manager) or working-class jobs (grocery clerk and factory worker).
Race had little effect on the doctors' responses. The study found that when the child was black, 45 percent of doctors believed there had "possibly" or "almost certainly" been abuse; another 32 percent were "unsure." If the child was white, 46 percent of pediatricians suspected abuse, with 28 percent saying they were unsure.
In contrast, there was evidence that parents' job descriptions swayed doctors' opinions.
When the child's family was lower-income, 48 percent of pediatricians thought there'd been abuse, versus 43 percent when the family was higher-income.
It's hard to know whether doctors' responses to a fictional case would be the same in real life.
And it's not clear, according to Laskey, whether attitudes about socioeconomic status might explain some of the racial differences in child abuse reporting seen in earlier studies.
She also stressed that she does not think pediatricians are consciously basing their diagnoses on parents' job titles. But in general, unconscious stereotypes can influence anyone's thinking.
"People tend to think that child abuse, or domestic violence, doesn't happen in upper-middle-class families, but of course it does," Laskey said.
It's important, she said, for doctors to be aware that unconscious generalizations could get in the way of diagnosing child abuse -- either missing it in kids from affluent families, or over-diagnosing it in children from poorer or minority families.
"My big take-home message for doctors is that we need to rely on the objective data," Laskey said.
It is true that studies have found children in poorer families to be at greater risk of abuse. But the poverty, itself, is not a "causative factor," Laskey said.
"Race and socioeconomic status shouldn't be things used in a diagnosis of abuse," she said.

Plant compounds tied to fewer heart deaths


1
NEW YORK (Reuters Health) - Older adults who get a moderate amount of certain plant compounds in their diets are less likely to die of heart disease or stroke, a large study finds.
The research, on nearly 100,000 older U.S. adults, found that those getting the most flavonoids in their diets were less likely to die of heart disease or stroke over the next seven years than those who ate the least flavonoids.
The compounds are found in a range of plant foods, including many fruits (like berries, citrus and apples) and vegetables (like kale, spinach and broccoli), nuts, soy, dark chocolate, tea and wine.
Research shows that flavonoids have a number of benefits, including fighting inflammation and acting as antioxidants -- which means they help protect body cells from damage that may lead to chronic diseases and cancer.
In the current study, the researchers divided participants into five groups according to the amount of flavonoids in their diets.
The one-fifth with the highest flavonoid intake were 18 percent less likely to die of heart problems or stroke than the fifth with the lowest intake.
That difference is "modest, but still relevant," said lead researcher Marjorie L. McCullough, of the American Cancer Society in Atlanta.
Given that heart disease and stroke are so common, even a modest risk reduction can make a big difference on the population level, McCullough noted in an interview.
It's not clear that flavonoids, themselves, actually lowered people's cardiovascular risks.
But flavonoid-rich foods are the types of foods we should be eating anyway, McCullough pointed out. "This provides further support for getting more of those foods in your diet," she said.
The findings, reported in the American Journal of Clinical Nutrition, are based on more than 98,000 men and women who filled out questionnaires on diet, lifestyle and medical history. At the time, they were about 70 years old, on average.
Over the next seven years, 2,771 people died of heart disease or stroke. That included 615 deaths in the fifth with the lowest flavonoid intake at the outset, and 515 deaths in the fifth with the highest intake.
When McCullough's team accounted for other factors -- like smoking, exercise habits and weight -- people getting the most flavonoids had an 18 percent lower risk of dying from cardiovascular trouble.
Flavonoid-rich foods also contain many other healthful nutrients, McCullough said. So it's hard to know whether the compounds, themselves, deserve the credit for the lower cardiovascular risks.
For example, another recent study linked magnesium-rich foods, which include nuts and dark leafy greens that are also high in flavonoids, to lowered stroke risk. (See Reuters Health story of January 13, 2012.)
The bottom line is that getting more plant foods in your diet may make a difference in your health and longevity, according to McCullough.
And these findings suggest it may not take a huge diet change, she said.
The people with the highest flavonoid intake in the study averaged about 20 servings of fruits and 24 servings of vegetables per week. The lowest-intake group got about 11 servings of fruit and 18 servings of vegetables per week.
Lower risks were also seen among older adults whose flavonoid intake fell in between the highest and lowest groups, however.
"So even adding one serving of flavonoid-rich food a day could be beneficial," McCullough said.
In general, experts recommend getting plenty of fruits and vegetables for the good of your overall health. The "DASH" diet recommended for lowering blood pressure and protecting your heart suggests four to five servings of fruit and the same number of vegetable servings each day.
A half cup of cooked vegetables or a medium-sized piece of fresh fruit would be examples of a serving.
One caveat, McCullough said, is to be careful not to douse your flavonoid-rich foods in sugar, fat or salt. "Try to keep them close to their natural form," she said.

Third smallest baby ever leaves US hospital


1
LOS ANGELES: A baby believed to be the third smallest birth-weight infant ever to survive left hospital in Los Angeles, doctors and the proud parents said.
Melinda Star Guido was born last August, 16 weeks early, weighing only 9.5 ounces (270 grammes) — less than a can of soda or the same as two iPhones — and has spent nearly five months in a neonatal intensive care unit.
“I am so excited to finally have my baby come home,” said her mother Haydee Ibarra, 22. “We have waited almost five months for this moment. It is so wonderful and we are ready to bring Melinda home.”
She is the third smallest baby to survive, according to Global Birth Registry figures cited by LA County health officials.

Dr Rangasamy Ramanathan, neonatology chief at the LA County-USC Medical Center, said he wasn’t initially sure if Melinda was going to survive beyond a few days.
“This doesn’t happen every day. In my 30 years here, … this is the first time it ever happened that we were able to discharge a baby who weighed less than 400 grams, or 300 grams,” he said.
“We have reached a milestone by being able to see Melinda go home,” he added “We are hopeful to see many more milestones accomplished in Melinda’s development as we follow her care over the next six years.”
