Bs. Bradshaw et al., POSTNEONATAL DIARRHEA MORTALITY OF MEXICAN-AMERICAN AND ANGLO-AMERICAN INFANTS - TRENDS AND CONTEXT, Population research and policy review, 16(3), 1997, pp. 225-242
In the 1930s and 1940s, the Mexican origin population of San Antonio,
Texas, USA, was desperately impoverished and inhabited some of the wor
st slums in the USA. Mortality of Mexican origin infants in the 1930s
and 1940s was dominated by diarrhea, a cause of death identified with
fecal contamination of the environment The postneonatal diarrhea morta
lity rate (risk) was 48 per 1,000 Mexican origin infants, but only 7 p
er 1,000 Anglo infants. By 1970 this cause of death had virtually disa
ppeared in both populations, but in the 35 years of 1935-1969, Mexican
origin infants accounted for over 90 percent of all diarrhea deaths i
n the city. Limited evidence suggests that miserable living conditions
without proper water supplies and sanitation in the densely settled M
exican American neighborhoods gave rise to environmental contamination
which resulted in high diarrhea morbidity and mortality. The hypothes
is is suggested that reduction of mortality from diarrhea was a conseq
uence of specific community interventions.
