Dear friends,

I found some abstracts of the new publications. I think they will be
interesting.

Does Increased Duration of Exclusive Breastfeeding Protect Against
Helicobacter pylori Infection? The Newcastle Thousand Families Cohort Study
at Age 49-51 Years.

OBJECTIVE:: Helicobacter pylori acquired in childhood is an important risk
factor for gastric carcinoma. Once colonization is established, infection
may be carried for life. This study used prospectively recorded, detailed
information on infant feeding and investigated the potential link between
duration of exclusive breastfeeding in infancy and seropositivity at age 50
years, as measured by enzyme-linked immunosorbent assay. METHODS:: H. pylori
seropositivity at age 50 years was investigated among 407 individuals born
in Newcastle in May and June 1947 and related to the duration of exclusive
breastfeeding after adjusting for measures of socioeconomic status and
adverse housing conditions at birth. RESULTS:: Duration of exclusive
breastfeeding in infancy was significantly associated with H. pylori
seropositivity (odds ratio per 30 days, 0.88; 95% confidence interval, 0.78
to 0.98). The significant protective trend was only seen among men (odds
ratio per 30 days, 0.78; 95% confidence interval, 0.65 to 0.95), with no
significant effect seen among women. CONCLUSION:: Increased duration of
exclusive breastfeeding in infancy may have a long-term protective effect
against chronic H. pylori infection and hence the risk of gastric carcinoma.
Although further research is required, particularly as to why a significant
effect was only seen among men, the results provide additional support for
the concept that breastfeeding may have long-term influences on health and
that human milk is the ideal complete first diet for human infants.

Breast-feeding influences cognitive development in filipino children.

Daniels MC, Adair LS.

University of North Carolina at Chapel Hill, Chapel Hill, NC 27516.

The importance of breast-feeding (BF) for cognitive development has been
researched widely over the past several decades. Although scholars agree
that children who breast-feed are generally more intelligent, it is
uncertain whether this advantage is due to BF effects or to other
accompanying healthy characteristics of women who breast-feed. This is a
problem in nearly every study, and even in studies controlling for known
confounding variables, residual confounding remains a concern. This study
tried a new approach, evaluating the relation between BF and cognitive
development or ability in a population in which BF was inversely correlated
with socioeconomic advantages and other healthy maternal behaviors. Normal
birthweight (NBW, n = 1790) and low birthweight (LBW, n = 189) (<2500 g)
infants born in 1983-84 in Metropolitan Cebu, Philippines were followed from
birth through middle childhood. Cognitive ability was assessed at ages 8.5
and 11.5 y with the Philippines Nonverbal Intelligence Test. Multivariable
linear regressions were created to estimate crude and adjusted relations of
various BF measures and later cognitive ability. After controlling for
confounding variables, scores at 8.5 y were higher for infants breast-fed
longer (1.6 points and 9.8 points higher among NBW and LBW infants,
respectively, breast-fed for 12 to <18 mo vs. <6 mo). BF coefficients in
both NBW and LBW 11.5-y models were attenuated but remained positive. This
analysis highlights the importance of long-term BF after initial
introduction of complementary foods, particularly in LBW infants born close
to term.
