In their early 20s girls suffering from increased stress levels are 42% more likely to have miscarriages. This is the conclusion reached by scientists from University College London and Zhejang University in China.
Researchers have shown that women who suffer from stress for a long time are 42% more likely to suffer miscarriages. This is the most significant confirmation that stress in the early period of a woman's young life has very serious consequences later. To date, there have been many studies on the effects of stress on pregnancy, but there has been no conclusive evidence of an association between stress and an increased risk of miscarriage. Note that miscarriage is the most common complication during pregnancy; it occurs before the 24th week in approximately 20% of cases. However, statistics often do not include those cases of miscarriages that occur at an earlier stage of pregnancy.
Researchers from the UK and China decided to conduct a systematic meta-analysis of the available data on the relationship between stress and miscarriage. It turned out that the risk of miscarriage is significantly higher in girls who, at the age of just over 20, suffered from increased levels of stress. This stress could be triggered by emotional trauma, social problems, worries about money, lack of harmony in relationships or marriage, problems at work, significant changes in personal circumstances, and previous loss of a child during pregnancy. Even after taking into account all other factors, the association between increased stress levels and subsequent risk of miscarriage persisted years later.
According to the researchers, this may be due to the activation and release of stress hormones into the body. They interfere with the biochemical pathways that the body needs to maintain pregnancy. Although chromosome abnormalities are often attributed to early miscarriages, this study suggests that high levels of psychological stress even before pregnancy are associated with an increased risk of miscarriages.
