Latino Loophole (aka 'Hispanic Paradox')
Brent Rooney ( email: firstname.lastname@example.org )
It has been an 'unsolved mystery' for over two (2) decades.
It is termed the 'Hispanic Paradox' (aka Latino Loophole).
Belonging to a below average socioeconomic stratum, young
Mexican immigrant women should have a raised premature
birth risk compared to native U.S. women. But 'mystery of
mysteries', Latino immigrants have a BELOW (!!!) average
preterm delivery risk.[1, Wommack] Have conventional
medical researchers 'punctured' this 'Hispanic Paradox'? Are
circles square? Do massive icebergs litter the Sahara Desert?
Does the 2013 U.S. President always tell the truth? With
over 90% of med researchers being 'politically correct', they
are still scratching their heads over this 'preemie paradox'.
Premature newborn babies have raised risk of 'MACE'
(Mental retardation, Autism, Cerebral palsy, Epilepsy) disorders,
plus higher odds of blindness, deafness, respiratory distress,
gastrointestinal injury and serious infections.
In 2009 via two (2) SRMAs (Systematic Reviews & Meta-
Analyses) it became SETTLED SCIENCE that prior IAs
(Induced Abortions) elevate preterm birth risk.[2, Swingle;
3, Shah] In theory, Latino women might be one group not
affected by the abortion-preemie risk. In 1986 professor Dr.
Michael Ross (UCLA) & colleagues tested over 20 potential
'preemie' risk factors for women in the Los Angeles, California
area.[4, Ross] The 1986 'Ross' abortion-preemie finding is
consistent with the 'Swingle' & 'Shah' systematic reviews,
with a reported 1.3 times the preterm birth risk for women
with prior IAs compared to women with zero prior IAs. 84%
of the women in the study were Latino women.[4, Ross]
In Mexico IA is NOT legal in most areas. It is reasonable to
believe that young Latino immigrants to the U.S. have a lower
IA prevalence compared to native U.S. women. This lower
IA prevalence is a major reason for the Latino 'Loophole' of
lower preterm birth rates than native U.S. women. But what
about daughters & granddaughters of such immigrant Latino
women? They tend to become acculturated & one consequence
of this is higher IA prevalence. What happens to the immigrant
Latino advantage of below average 'preemie' rate? It is NOT
enjoyed by 2nd, 3rd, and subsequent Latino generations.
Racism explains high Black-American 'preemie' rate?
Black-American women, with more than quadruple the IA
rate as non-Black-American women have triple the risk of
delivery under 32 weeks' gestation (i.e. very preterm)
compared to non-Black-Americans.[5, Rooney] Such very
preterm babies have fifty-five (55) times the CP (Cerebral
Palsy) risk as full-term newborns, according to the 2008
Eveline Himpens et al. meta-analysis.
Luck of the Irish?
The U.S. has a 'preemie' rate of about 12% (one birth in 8).
In the U.K. women in the Republic of Ireland (where IA is not
legal) have a low preterm birth rate [6, Calhoun], in fact, less
that one-half the U.S. rate. If the Republic of Ireland legalizes
induced abortions, much of this 'preemie' prize will disappear.
