Although I found much of the
information about the correlation between race and incidents of low birth
weight presented by Conley, Strully, and Bennett in The Starting Gate to be useful and compelling, I was plagued by one
nagging question in the back of my mind while I was reading: What do they mean
when they say race? To the best of my knowledge, a specific definition of race
was never put forth in the book, and this left me feeling a bit confused.
Depending on the context, race may
mean many different things to different people. In some instances it may refer
to skin color, while in other instances it may refer to common ancestry,
however these two things are not necessarily related. For example, sub-Saharan
Africans and Australian Aborigines have similar skin colors, but very different
ancestries. Also self-reported race may be different from either skin color or
ancestry. For example, a person may classify himself or herself as black, but
have a significant percent of ancestors from Europe or have a fair skin tone.
This makes the term “race” rather vague unless it is specifically defined.
Race is also a tricky term because
the divisions between races, whether in skin color or ancestry, are not always
clear-cut. Because there has been so much racial mixing, especially in the
United States, a person may have characteristics of more than one race and this
makes it difficult to define them as one or the other. According to the latest
U.S. census, approximately 2.9 percent of Americans, or 9 million people,
define themselves as multiracial and that number is rapidly growing.
When we are not sure exactly what
the term race means, it becomes difficult to make inferences based on the data
presented in the book. Although I think that looking at differences in certain
diseases among different races is a useful tool for determining both social and
biological factors contributing to the disease, it has to be well defined
otherwise it becomes less meaningful.
I agree that using race to propose correlation or causation of birth weight is very tricky. Race is yet to be defined and it loses its meaning especially when describing blacks who have European, African and Native-American ancestry. The idea that LBW is linked to a racial group makes more sense if the group had low genetic diversity or if LBW is like Tay-Sachs disease and linked to a specific gene and community. Considering the high genetic diversity among blacks and that race is just social construct, the real question is what issues do many blacks have in common? Is it nutrition, stress, socioeconomic status or other environments created via racism in America?
