Conceived in stress
M. L. Tan
Filipinas sometimes
startle foreigners when they say, "I’m conceiving." From a
westerner’s perspective, conception is a moment, the point when sperm
and ovum say hello.
Not so with Filipinos.
Our term paglilihi refers to a "conceiving" process that
stretches through the first few weeks of pregnancy. It is a crucial
period that’s believed to determine the child’s health and, some
say, even the child’s features. During this period, a mother’s every
wish, every craving, has to be satisfied, or else the child’s health
will be adversely affected.
Doctors often dismiss
these beliefs as being unscientific but there is accumulating evidence
to show that a mother’s health during pregnancy does have many effects
on the child, including some that affect the child all throughout his or
her life.
Some of the more
immediate effects are obvious. Pregnant women who are malnourished, or
who smoke, drink or use other drugs (nicotine and alcohol are drugs,
too, in case you’ve forgotten), have greater chances of delivering
babies with low birth weight. That’s defined as a weight of less than
2.5 kilos or 5.5 pounds. Low birth weight babies tend to be more sickly,
and may die during infancy or childhood. The survivors continue to be
rather sickly, and their cognitive development may be impaired.
Some studies now show
that the mother’s health may affect children way beyond childhood. For
example, because of the war and a severe winter, the Dutch had serious
food shortages in 1944-45. Researchers found that the child born to
women who were pregnant during this Dutch Hunger Winter actually had
normal weights at birth, but when they reached adulthood, many of more
them had diabetes.
Similar findings are
now being reported in different parts of the world – from Finland to
India – demonstrating correlation between a mother’s condition
during pregnancy and the child’s predisposition, in adulthood, to
diabetes, high blood pressure and cardiovascular diseases.
It’s not just a
matter of maternal nutrition, or the woman’s use of drugs, that
affects the child. The key is stress – whether from the mother’s own
condition or her external environment -- which triggers the production,
in the pregnant woman, of more stress hormones. These pass through the
placenta and reach the fetus. Experiments in animals found that exposing
fetuses to stress hormones resulted in high blood pressure and elevated
blood glucose levels, and that these conditions worsened as the animals
grew older.
Remember the stress
hormones – adrenaline for example – are actually helpful hormones.
When we face a stressful situation, our bodies prepare us to respond to
the situation by pumping out adrenaline. Our hearts beat faster, we
hyperventilate, and our blood pressure shoots up. All that enables us to
respond appropriately, sometimes described as the "fight or
flight" mode.
The adrenaline levels
should drop back to normal after the crisis is over, otherwise, your
body shuts down and you go into shock from the overload. A similar
situation exists with the other stress hormones. Researchers believe
that a fetus exposed to stress hormones may result in the brain being
"hard-wired" or conditioned to keep operating on a permanent
stress mode, producing the hormones even when you don’t need them.
Thus your blood pressure or blood sugar stay elevated, and become
chronic conditions.
There are other little
explanations and theories to show how maternal stress affects the
child’s future development but it’s interesting how they all support
our popular notions of paglilihi. This notion of a prolonged period of
"conception" is one way our culture allows our overworked
women – to rest, and to get the food they need. They’re even
entitled to special treats, like getting that fruit that isn’t in
season, or being able to say no to their husband.
Our notions of
paglilihi also support the wisdom of family planning. Our pregnant
mothers go through so much stress with poverty, civil strife and war,
but all that stress is further amplified if the woman is pregnant every
year, or even every other year, with harmful effects on the mother and
the child.
Even if the mother and
child survive the pregnancy, it will an uphill battle with the sickly
and malnourished child. The recent medical findings that I just
described remind us that entire societies have to pay for the costs of
all this stress, not just in terms of sickly children but of more adults
having diabetes, high blood pressure and heart disease.
I’ve wondered, at
times, about the children born between 1983 and 1986, during the
turbulent economic and political crisis following Aquino’s
assassination. They are coming of age now, only to enter another serious
crisis. I fear that ill health in Filipino mothers and children has
become a vicious cycle, with one generation after another conceived,
born and raised in stress.
