Relationship Stress May Influence Heart Health in Men
A new study discovers risk factors for heart health appear to be linked to changes over time in the quality of marital relationships — at least for men.
The research provides new insights between marital status and health. Prior findings have revealed an association between marital status and health, but it is not clear whether this observed link is influenced by the health of people entering into marriage or the protective effects of the marriage itself.
Most studies that have looked at marital quality and the risk of cardiovascular disease have focused on single point in time, rather than examining the potential impact of changes over time.
In a bid to rectify this, the researchers tracked changes in cardiovascular risk factors for 620 married fathers taking part in the Avon Longitudinal Study of Parents and Children (ALSPAC), which began in 1991. The study appears online in the Journal of Epidemiology & Community Health.
In the investigation, the dads completed a 12-item validated questionnaire (measure of intimate bonds scale) to assess the quality of their marital relationship when their child was nearly three and again when their child was nine.
Relationship quality was defined as consistently good; consistently bad; improving; or deteriorating.
The researchers assessed the dads’ blood pressure, resting heart rate, weight (BMI), blood fat profile, and fasting glucose levels between 2011 and 2013 when their child was nearly 19, on the basis that it would take some time for changes in cardiovascular risk factors to occur after any corresponding changes in relationship quality.
The results showed little change in cardiovascular risk factors for men whose relationships with their spouses were consistently good or bad.
However, a different pattern emerged for those whose relationships had either improved or deteriorated during the study period, although the effects in absolute terms were small.
After taking account of potentially influential factors, such as age, educational attainment, short stature, and household income, improving relationships were associated with lower levels of low density lipoprotein (‘bad’ cholesterol) and relatively lower weight when compared with consistently good relationships.
Moreover, when a relationship was on the upswing, males showed improved total cholesterol and improved diastolic blood pressure, albeit the effects were mild.
Deteriorating relationships, on the other hand, were associated with worsening diastolic blood pressure.
“Traditionally, beneficial effects of marital status were thought to be mediated by either health selection, confounding by socioeconomic status, or psychosocial mechanisms,” write the researchers.
“The latter argument has been used to support the observation that men appear to gain more benefit than women, as women have larger social networks and are less dependent on their partner than men,” they add.
Researchers believe the reason risk factors remained stable when a relationship is viewed as consistently good or bad, could be because of some degree of ‘habituation’ over time or differences in individual perception of relationship quality.
The scientists are quick to point out that the data came from an observational study, so no firm conclusions can be drawn about cause and effect. Additionally, a large number of participants dropped out of the study and the findings only applied to men.
Because the study participants are still relatively young, it isn’t clear whether the patterns they found will be reflected in actual rates of disease in future, they say. Further monitoring of the participants would be required.
In summary, researchers conclude that marriage counselling for couples with deteriorating relationships may have added benefits in terms of physical health over and above psychological well-being — though in some cases ending the relationship may be the best outcome.
