Foretelling my talk todayA new concept today of evolutionary mismatch that honors wisdom and scienceSolving linked multi-problems or syndemics instead of one-at-a-timeUsing low-cost proven strategies for all as public-health policy for Maternal and Child Health (MACH)
Tuesday, December 11, 12
My Three Easy Pieces for Today• Policy Goal 1: Reduce multiple sources of neuro-inflammation before pregnancy,
during pregnancy and during childhood—using low-cost, scientifically proven evidence-based kernels.
• Policy Goal 2: Recognize, reinforce and reward non-use of tobacco, alcohol & other drugs among women of childbearing age —using low-cost, scientifically proven evidence-based kernels.
• Policy Goal 3: Create public-private partnerships to promote specific nurturing environments actionable strategies for children and their caregivers.

A policy…A course or principle of action adopted or proposed by a government, party, business, or individual.
Also, archaic, prudent or expedient conduct or action: a course of policy and wisdom.
ORIGIN late Middle English: from Old French policy ‘civil administration,’ via Latin from Greek politeia ‘citizenship,’ from politēs ‘citizen,’ from polis ‘city.’policy 2 |ˈpäləsē|noun ( pl. policies )
ORIGIN mid 16th cent.: from French police ‘bill of lading, contract of insurance,’ from Provençal poliss(i)a, probably from medieval Latin apodissa, apodixa, based on Greek apodeixis ‘evidence, proof,’ from apodeiknunai ‘demonstrate, show.’

www.thisviewoflife.com “Look up Evolutionary Mismatch”Natural selection adapts organisms to their past environments and has no ability to foresee the future.
When the environment changes, adaptations to past environments can misfire in the current situation, producing a mismatch that can only be solved by evolving or by modifying the current environment.
Mismatches are an inevitable consequence of evolution in changing environments.

Some observable trends:• Increased postpartum depression
• More addictions
• More “inflammatory” diseases like asthma, diabetes and obesity
• More children with disabilities such as autism spectrum disorder
• Higher lifetime rates of mental, emotional, behavioral, and related physical disorders

2006 Statistics Canada report on the Participation and Activity Limitation Survey (PALS)
• According to Statistics Canada, more children in this country have a learning disability than all other types of disabilities combined.
• According to Statistics Canada, of all the children with disabilities in this country, more than half (59.8%) have a learning disability.
• According to Statistics Canada, more than half a million adults in this country live with a learning disability, making it more challenging for them to learn in universities and colleges, and on the job.
• According to Statistics Canada, learning disabilities increased considerably between 2001 and 2006 among Canadians aged 15 and over by almost 40 per cent to 631,000 people, making it one of the fastest growing types of disabilities in Canada that isn’t related to aging.

Relation of Schizophrenia Prevalence to Latitude, Climate, Fish Consumption, InfantMortality, and Skin Color: A Role for Prenatal Vitamin DDeficiency and Infections?

Previous surveys found a large (>10-fold) variation inschizophrenia prevalence at different geographic sitesand a tendency for prevalence to increase with latitude.We conducted meta-analyses of prevalence studies to inves-tigate whether these findings pointed to underlying etiologicfactors in schizophrenia or were the result of methodolog-ical artifacts or the confounding of sites’ latitude with levelof healthcare at those sites. We found that these patternswere still present after controlling for an index of health-care—infant mortality—and focusing on 49 studies thatused similar diagnostic and ascertainment methods. Thetendencies for schizophrenia prevalence to increase withboth latitude and colder climate were still large and signif-icant and present on several continents. The increase inprevalence with latitude was greater for groups with lowfish consumption, darker skin, and higher infant mortali-ty—consistent with a role of prenatal vitamin D deficiencyin schizophrenia. Previous research indicates that poor pre-natal healthcare and nutrition increase risk for schizophre-nia within the same region. These adverse conditions aremore prevalent in developing countries concentrated nearthe equator, but schizophrenia prevalence is lowest atsites near the equator. This suggests that schizophrenia-producing environmental factors associated with higher lat-itude may be so powerful they overwhelm protective effectsof better healthcare in industrialized countries. The ob-served patterns of correlations of risk factors with preva-lence are consistent with an etiologic role for prenatalvitamin D deficiency and exposure to certain infectious dis-eases. Research to elucidate environmental factors that un-
derlie variations in schizophrenia prevalence deserves highpriority.

Introduction
Schizophrenia is an unusually burdensome disorder be-cause of the great economic costs of extensive care andloss of economic productivity, as well as the personal suf-fering and stigma, which often affect a patient and his orher family for most of the patient’s life. Moreover, formost patients there is still no cure or even an effectiveway of treating many of the most disabling, ‘‘negative’’symptoms of the disorder. Therefore, a key goal of schizo-phrenia research is elucidation of etiologic factors, partic-ularly environmental ones that could be readily avoidedand used in effective, inexpensive, and ethically sound pri-mary prevention programs.In a comprehensive survey of schizophrenia prevalence
studies around the world that were published in Englishover a period of 4 decades, Torrey1 noted 2 importantpatterns. First, prevalence rates varied widely at differentgeographic sites, with the highest rate being more than 10times greater than the lowest. Second, there was a strongtendency for schizophrenia prevalence to increase withincreasing latitude; ie, prevalence rates tended to bevery low near the equator and to increase as one movedtoward the poles. Both of Torrey’s conclusions were alsoreached in a survey and meta-analysis by Saha et al,2
which included more recent studies as well as ones pub-lished in languages other than English. Several other sur-veys have also concluded that schizophrenia rates vary atleast 10-fold around the world, including studies usingmeasures of point prevalence, lifetime prevalence, andincidence.1,3–10
A number of explanations have been proposed for thisvariability inprevalence.Severalcomplementary linesofre-search suggest that the tendency for schizophrenia preva-lence to increase with latitude and cold climate may bedue, at least inpart, to someunderlyingpre-orperinatal en-vironmental influences. For example, several studies have

different sites around the world1,2 were not simply arti-facts of differences in diagnostic and ascertainment meth-ods used by different studies. Even though our analysesrestricted prevalence studies to those that used more sim-ilar research methods for diagnosis and ascertainment ofschizophrenia cases, our analyses also found (a) thatprevalence rates varied more than 10-fold across geo-graphic sites and (b) that prevalence increased markedlywith increasing latitude.
That the correlation of schizophrenia prevalence withlatitude is both robust and large, and is not due simply tobetween-site differences in diagnostic and ascertainmentmethods, is further suggested by analysis of data collectedby Lehtinen et al.42 Their study is particularly informa-tive because it is the study that best controlled for possi-ble methodological sources of differences in prevalence atdifferent geographic sites; the same investigative person-nel, as well as the same methods, were used to obtainprevalence rates at several different sites within thesame country. Those investigators studied schizophreniaprevalence at 5 different Finnish sites in the same timeperiod, using a consistent set of diagnostic criteria andascertainment methods, and their data showed a veryhigh correlation of prevalence with both latitude(r = .97, P < .01) and mean low temperature (r =!.99, P < .001).
Athigher latitudes, there isanespeciallywidevariation inprevalence rates. By contrast, near the equator, prevalencefor all sites tends to be quite low. That is, for all groups andcontinental regions for which there are data frommultiplesites, thebest-fit (least squares) regression lines all havepos-
itiveslopes,andtheslopes tendtobesteeper forsitesathigh-er latitudes.This is evident by inspecting table 1, but ismostreadily visualized in figure 1.The results suggest that etiologic factors closely asso-
ciated with latitude and cold climate may be much morepowerful contributors to risk for schizophrenia than isgenerally recognized. The general level of a population’seconomic status and healthcare, as indexed in our anal-ysis by the infant mortality rate, appears to be a muchweaker predictor of risk for schizophrenia than are lati-tude and winter temperature. A high infant mortality rate

Previous surveys found a large (>10-fold) variation inschizophrenia prevalence at different geographic sitesand a tendency for prevalence to increase with latitude.We conducted meta-analyses of prevalence studies to inves-tigate whether these findings pointed to underlying etiologicfactors in schizophrenia or were the result of methodolog-ical artifacts or the confounding of sites’ latitude with levelof healthcare at those sites. We found that these patternswere still present after controlling for an index of health-care—infant mortality—and focusing on 49 studies thatused similar diagnostic and ascertainment methods. Thetendencies for schizophrenia prevalence to increase withboth latitude and colder climate were still large and signif-icant and present on several continents. The increase inprevalence with latitude was greater for groups with lowfish consumption, darker skin, and higher infant mortali-ty—consistent with a role of prenatal vitamin D deficiencyin schizophrenia. Previous research indicates that poor pre-natal healthcare and nutrition increase risk for schizophre-nia within the same region. These adverse conditions aremore prevalent in developing countries concentrated nearthe equator, but schizophrenia prevalence is lowest atsites near the equator. This suggests that schizophrenia-producing environmental factors associated with higher lat-itude may be so powerful they overwhelm protective effectsof better healthcare in industrialized countries. The ob-served patterns of correlations of risk factors with preva-lence are consistent with an etiologic role for prenatalvitamin D deficiency and exposure to certain infectious dis-eases. Research to elucidate environmental factors that un-

Introduction
Schizophrenia is an unusually burdensome disorder be-cause of the great economic costs of extensive care andloss of economic productivity, as well as the personal suf-fering and stigma, which often affect a patient and his orher family for most of the patient’s life. Moreover, formost patients there is still no cure or even an effectiveway of treating many of the most disabling, ‘‘negative’’symptoms of the disorder. Therefore, a key goal of schizo-phrenia research is elucidation of etiologic factors, partic-ularly environmental ones that could be readily avoidedand used in effective, inexpensive, and ethically sound pri-mary prevention programs.In a comprehensive survey of schizophrenia prevalence
studies around the world that were published in Englishover a period of 4 decades, Torrey1 noted 2 importantpatterns. First, prevalence rates varied widely at differentgeographic sites, with the highest rate being more than 10times greater than the lowest. Second, there was a strongtendency for schizophrenia prevalence to increase withincreasing latitude; ie, prevalence rates tended to bevery low near the equator and to increase as one movedtoward the poles. Both of Torrey’s conclusions were alsoreached in a survey and meta-analysis by Saha et al,2
which included more recent studies as well as ones pub-lished in languages other than English. Several other sur-veys have also concluded that schizophrenia rates vary atleast 10-fold around the world, including studies usingmeasures of point prevalence, lifetime prevalence, andincidence.1,3–10
A number of explanations have been proposed for thisvariability inprevalence.Severalcomplementary linesofre-search suggest that the tendency for schizophrenia preva-lence to increase with latitude and cold climate may bedue, at least inpart, to someunderlyingpre-orperinatal en-vironmental influences.

Even though our analysesrestricted prevalence studies to those that used more sim-ilar research methods for diagnosis and ascertainment ofschizophrenia cases, our analyses also found (a) thatprevalence rates varied more than 10-fold across geo-graphic sites and (b) that prevalence increased markedlywith increasing latitude.
That the correlation of schizophrenia prevalence withlatitude is both robust and large, and is not due simply tobetween-site differences in diagnostic and ascertainmentmethods, is further suggested by analysis of data collectedby Lehtinen et al.42 Their study is particularly informa-tive because it is the study that best controlled for possi-ble methodological sources of differences in prevalence atdifferent geographic sites; the same investigative person-nel, as well as the same methods, were used to obtainprevalence rates at several different sites within thesame country. Those investigators studied schizophreniaprevalence at 5 different Finnish sites in the same timeperiod, using a consistent set of diagnostic criteria andascertainment methods, and their data showed a veryhigh correlation of prevalence with both latitude(r = .97, P < .01) and mean low temperature (r =!.99, P < .001).
