The health effects of sensitive, responsive parenting

When we talk about the benefits of sensitive, responsive parenting, we often focus on emotional and cognitive outcomes.
suggests that kids raised by warm, nurturing parents develop better
emotional regulation, more empathy, and more advanced reasoning skills. They may even test with higher IQs.
But there may be powerful health benefits too. Particularly for kids growing up in otherwise adverse environments.
To see what I mean, consider the stress of children of lower socioeconomic status, or SES.
kids experience higher daily levels of the stress hormone cortisol,
which increases their risk of developing metabolic syndrome--a whole
package of medical problems that include obesity, cardiovascular
disease, and diabetes.
Stress may also turn on genes that cause inflammation.
University of British Columbia psychologists Gregory Miller and Edith
Chen tested adolescents for biochemical markers of the system that
regulates inflammation in the body, they found that kids of lower
socioeconomic status were more likely to develop a “pro-inflammatory
Such a phenotype puts the individual at higher risk
for developing inflammatory diseases like atherosclerosis, autoimmune
disorders, and cancer (Miller and Chen 2007).
Can parents protect kids from the physiological effects of stress?
It makes sense.
responsive parents make children feel safe. They make kids less
suspicious of other people, and therefore more relaxed.
may reduce long-term wear and tear on the body caused by physiological
stress (Chen et al 2011). And by teaching their kids how to regulate
their own emotions, parents may help children cope with stressors
(Repetti et al 2002).
So Chen and Miller have turned their attention to the health effects of parenting on children of lower socioeconomic status.
one study, Chen and her colleagues asked 53 healthy young adults (who
grew up under low SES conditions) about their parents. Study volunteers
who expressed the most warmth toward their mothers showed fewer signs of
systemic inflammation (Chen et al 2011).
second study, Miller and his team explored the effects of parental
warmth and sensitivity on the development of metabolic syndrome.
The researchers asked over 1200 middle-aged Americans questions about their parents. Questions like:
“How much did your parent understand your problems and worries?"
“How much time and attention did s/he give you when you needed it?"
Next, the researchers examined participants for symptoms of metabolic
syndrome (like “apple"-shaped central obesity, high blood pressure, and
a bad cholesterol profile).
As expected, people who grew up in families of low socioeconomic status (SES) were more likely to have these symptoms.
about 45% of the people with low SES childhoods were symptom-free. And
these symptomless people were more likely to have had nurturing
Among kids with the most nurturing mothers, there was no correlation between SES and poor health status.
put this in perspective, the researchers also tested the effects of
being upwardly mobile. If you were born relatively poor, but achieved
higher SES as an adult, did you enjoy better health?
the answer was no. Not when it came to symptoms of metabolic syndrome.
The researchers couldn’t detect any difference between people who stayed
poor and people who moved up the socioeconomic ladder.
Is this proof that sensitive, responsive parenting has a lasting impact on health?
studies don’t control for genetic factors. Perhaps nurturing parents
are more likely to carry genes that confer better health.
Perhaps, too, the results are skewed by the participants’ inaccurate reports of their parents’ behavior.
what about fathers? Miller and his colleagues didn’t find evidence of
any effect for nurturing dads. Just moms. Is that because the fathers in
this study were less involved with childcare?
So there are important questions for future studies to address.
in the meantime, there is evidence from other types of research, evidence supportive of the idea that nurturing parents
can act as a buffer against the long-term effects of childhood stress.
For instance, experiments on nonhuman animals suggest that the behavior of family members can have a dramatic impact on physical outcomes.
Cross-fostering experiments on rats have demonstrated that individuals develop lower levels of stress reactivity if they were raised by highly
responsive mothers (Francis et al 1999; Meaney 2001). In experiments
on zebra finches, Pat Monaghan and her colleagues found that birds
with highly reactive, "stressed out" temperaments
lived longer when paired with calmer, laid-back mates (Pat Monaghan et
And new, longitudinal studies of humans are supportive as well. As I note in this blog post, a recent fMRI study suggests that sensitive, responsive parents can protect children from the brain-shrinking effects of toxic stress (Luby et al 2013). And research tracking babies exposed to prenatal stressors found that infants developed normally if their mothers exposed them to lots of physical affection (Sharp et al 2012).
