Strong family relationships may help with asthma outcomes for children

July 18, 2019

EVANSTON, Ill. --- Positive family relationships might help youth to maintain good asthma management behaviors even in the face of difficult neighborhood conditions, according to a new Northwestern University study.

For children with asthma, neighborhood environmental conditions -- the role of allergens and pollutants, for example -- have long been known to play an important role, but less is known about how social conditions in the neighborhood might affect children's asthma.

In the study, researchers sought to test whether there are social factors that can buffer children from the negative effects of difficult neighborhood conditions, focusing on one particular factor they thought would be important in the lives of children -- whether they had positive and supportive family relationships.

"We found significant interactions between neighborhood conditions and family relationship quality predicting clinical asthma outcomes," said Edith Chen, professor of psychology in the Weinberg College of Arts and Sciences, faculty fellow at the Institute for Policy Research at Northwestern and lead author of the study. "When children lived in neighborhoods that were high in danger and disorder, the better their family relationships, the fewer symptoms and activity limitations they had, and the better their pulmonary function."

In contrast, Chen said, when children lived in neighborhoods that were lower in danger and disorder, their symptoms, activity limitations and pulmonary function were generally good, and the nature of their family relationships didn't really matter.

Using Google Street View, the researchers were able to take a virtual walk through each of the research participant's Chicago neighborhoods, and code for indicators of neighborhood danger or disorder, including evidence of graffiti, rundown or abandoned cars, bars or grates on windows and doors, and abandoned or boarded-up homes. That gave them a more objective indicator of the level of neighborhood danger and disorder that a participant is likely experiencing on a daily basis as they walk to places from their home.

They then interviewed children about their family relationships and coded the amount of support, trust and conflict that was present, and measured a variety of asthma outcomes -- clinical, behavioral and biological -- in these children.

Chen said the research is important to the field of pediatrics because families often don't have options for moving out of neighborhoods that are challenging.

"If pediatricians can provide suggestions to families about how supportive relationships can help with managing their child's asthma, while at the same time still acknowledging the realities of the ongoing neighborhood difficulties that many of these families face, this might help families," Chen said.

"It's possible that when children have high-quality relationships with their family, family members are able to help their children prioritize asthma management, for example, perhaps by shielding them from neighborhood stressors in order to minimize the disruption to asthma routines," Chen said. "But this is speculative at this point, and future research could test this idea by implementing family or parenting interventions in youth with asthma who live in high-danger neighborhoods and examining their effects on childhood asthma outcomes."

First things first: our very own Latif Nasser has an exciting new show on Netflix. He talks to Jad about the hidden forces of the world that connect us all. Then, with an eye on the upcoming election, we take a look back: at two pieces from More Perfect Season 3 about Constitutional amendments that determine who gets to vote. Former Radiolab producer Julia Longoria takes us to Washington, D.C. The capital is at the heart of our democracy, but it's not a state, and it wasn't until the 23rd Amendment that its people got the right to vote for president. But that still left DC without full representation in Congress; D.C. sends a "non-voting delegate" to the House. Julia profiles that delegate, Congresswoman Eleanor Holmes Norton, and her unique approach to fighting for power in a virtually powerless role. Second, Radiolab producer Sarah Qari looks at a current fight to lower the US voting age to 16 that harkens back to the fight for the 26th Amendment in the 1960s. Eighteen-year-olds at the time argued that if they were old enough to be drafted to fight in the War, they were old enough to have a voice in our democracy. But what about today, when even younger Americans are finding themselves at the center of national political debates? Does it mean we should lower the voting age even further? This episode was reported and produced by Julia Longoria and Sarah Qari. Check out Latif Nasser's new Netflix show Connected here. Support Radiolab today at Radiolab.org/donate.
