Relationship Dissatisfaction Ups Risk of Infection during Pregnancy

Relationship Issues May Up Risk of Infection During Pregnancy

A new study suggests a bad relationship during pregnancy increases the risk of infection in both the mother and the newborn. The study suggests emotional health can influence infectious disease in the mother and the risk can be transferred in the womb to impact the physical health of a newborn.

“My study does not prove that the first thing leads to the second. But those who report that they are dissatisfied in their relationship more often report illnesses during pregnancy. Their children are also reported ill more often during their first year,” said Roger Ekeberg Henriksen, who recently defended his Ph.D. thesis at the University of Bergen.

“If you compare the group of pregnant women with the lowest satisfaction to the group with highest satisfaction in their relationship, the first group’s risk of becoming ill is more than twice that of the second group.”

Henriksen said the gap between the groups is major. He added that the respondents’ level of education and income were above average, and so is the level of satisfaction in their relationship. But since the study is so comprehensive, all levels of society are represented.

When it comes to the children, the connections are even more obvious than with the pregnant women. In the study researchers examined the occurrence of eight different infectious diseases, from the common cold to stomach flu and inflammation of the ear.

They discovered in children up to six months of age that the occurrence of all eight infections was higher when the mothers were dissatisfied in their relationship.

In his thesis, Henriksen refers to research on stress in order to explain the connections between bad relations and physical illness.

“Relationship researchers have been interested in psychological factors such as depression and life quality. These are, of course, interesting and relevant factors. But when I was working with my master’s thesis, which was about shyness and somatic diseases, I was surprised to see how social isolation and loneliness directly affect the physiology.”

“You have a psychological experience, but how does this become a physical illness that makes you vomit or gives you a fever of a cough? This is an exciting path. If the idea is that stress makes us ill, we’ve already seen that there are individual variations and that social support is important.”

Henriksen explains that stress responses are completely natural to the body.

“For instance, they enable us to mobilize quickly in order to avoid dangers. In such situations, some bodily functions are prioritized before others, and the brain in particular is given extra energy under stress. When the stress response is transferred to the unborn child during pregnancy, evolution researchers claim that this helps the unborn child prepare for the world outside.”

It is not natural to remain in a stressed condition, however. If this happens, our immune system may be given lower priority, and we thus become less resistant towards infectious diseases from bacteria and viruses. According to Henriksen, this is the effect that comes into play in his research.

“If we look at brain research and other research on physiological mechanisms, we see that having a partner who is predictable and supportive may be decisive for our ability to handle stress. On the opposite side, stress responses may occur with the absence of social support.”

The thesis is based on the Norwegian Mother and Child Cohort Study (MoBa), a health study that has been collecting data about mothers and their children since 1999. The study of pregnant women’s infectious diseases includes more than 67,000 women. The study of children’s infectious diseases includes nearly 91,000 women and more than 100,000 children.

In order to measure contentment in the relationship, the women in the survey have responded to whether or not they agree with ten statements such as “My partner and I have a close relationship,” “I often think about ending the relationship” and “I’ve been fortunate in my choice of partner.” An average value was then estimated and used in the analyses.

“This is a relatively well-validated instrument,” Henriksen said. “We have research showing that mothers who are not doing too well are quicker to report symptoms with their children than others. But we have reason to believe that there is a clear connection here, not least because we see such a consistent pattern.”

Previous studies have shown similar connections. But none of the studies can maintain with certainty whether their findings reflect biological effects or other factors that affect the mothers and children’s health indirectly. Henriksen is hoping that further research on the field may contribute to filling a knowledge gap.

“For a long time we’ve been aware of the fact that stress may have a negative effect on your health, but it’s important to draw attention to the fact that social relations are at least as relevant as other factors. This applies to both partner relationships and social support from friends and family. In many instances this is also something that can be easily improved.”
