The joint research team investigated 373 pairs of couples over 16 years in order to investigate the negative influence of disagreement such as "child care" "money" "hobby" etc. on health.

This survey is to distribute a questionnaire form to the target couple (both husband and wife) and ask themselves to evaluate their health status in 5 stages, with a rating of 5. Then a good couple got a score of 4.07 from the start of marriage, but an average number of married couple was 3.86 from the start, and it was 0.2 points lower than a good couple. As the score afterwards gradually goes down as well as a good couple and a bad couple, we can see that the score is low at the start is a very bad sign.

In the survey, we are investigating not only the health condition but also the number of topics that differ in opinion between married couple such as childcare and hobbies. Then, the health condition of the wife did not affect the number of topics a little, but it became clear that the husband 's health condition decreases as the number of topics increases.

"I understand that marriage has the effect of improving the health of people with high cholesterol and heart diseases, but I think that marriage has been repeated many times between married couple," said Rosie Shuulout, International Person Relations Association (IARR) When collisions occur many times, it will give a negative health effect equal to smoking and drinking. "

Veronica Lamarsch, professor of social psychology at the Essex University in the UK, said, "It is known that deteriorating relationships can cause various health hazards such as overeating and refusing, influences on the immune system, due to increased stress" As men and women trouble pointed out that there is a possibility of causing health effects. "It is important to make effective communication to improve the relationship between married couple," he said.
