For decades, pregnancy advice has been directed exclusively at mothers, but a new study turns this notion on its head and reveals that fathers’ health and pre-pregnancy behaviors play a crucial role in their children’s future health.
The study, conducted by the University of Southampton in collaboration with international partners from University College London, the United States, New Zealand, and Singapore, confirms that the father’s health and behavior before pregnancy have a significant impact on the health of the mother and fetus, and in some cases, the father’s influence is even stronger than the mother’s.
Researchers discovered that a man's overall health—his weight, age, substance use, and even mental health—all influence pregnancy and its outcomes. Even more surprisingly, a man's childhood experiences, such as exposure to stress or the environmental conditions in which he lived, can have repercussions on his children's health later in life.
The multidisciplinary study relied on evidence from biological, behavioral, and social sciences, with the aim of developing an integrated framework for the role of men in preparing for pregnancy and fatherhood, which is medically known as "preconception health".
Dr. Danielle Schonecker from the research team explained that a man’s early experiences (such as stress, education, environment, and physical and mental health) affect his health at reproductive age, and these factors in turn affect his wife’s health and behaviors before and during pregnancy, in addition to direct biological effects on the fetus.
She says: "Our results show that a man's early life experiences, including stress, physical and mental health, environment, and educational level, directly affect his health during his reproductive years. These factors, in turn, are reflected in his partner's health and health behaviors before and during pregnancy, in addition to their direct biological effects on the developing fetus."
Professor Keith Godfrey, lead author of the study from the University of Southampton and the Southampton Biomedical Research Centre, explained that previous research had largely neglected the impact of fathers on pregnancy and parenthood. He added, "It is now clear that fathers have a real influence on pregnancy. Their health and behaviors, such as weight, substance use, and age, all affect the outcomes of pregnancy and the child, not just the health of the pregnant mother. In some ways, the father's influence is stronger than the mother's, and some of these influences are linked to the fathers' experiences from childhood."
Researchers emphasize that improving pre-pregnancy health is a shared responsibility that falls on policymakers, public health agencies, clinicians, researchers, and men themselves.
Professor Godfrey concluded his remarks by saying: “Investing in the health and well-being of boys and young people is key to reducing health disparities and improving outcomes for future generations. Raising awareness of the importance of men’s health does not diminish the vital importance of women’s and pregnant women’s health, but rather is a collective call to ensure that men and partners are equipped to be supportive partners, allies, and caregivers before, during, and long after pregnancy.”
