Father's age linked to blood cancer
risk in his kids
Washington: A
new study links a father's age at the birth of his child to the risk that the
child will develop blood and immune system cancers as an adult, particularly
for single kids.
However, the study found
no association between having an older mother and these cancers.
"The lifetime risk of these cancers is fairly low -
about one in 20 men. Still, the study does highlight the need for more research
to confirm these findings and to clarify the biologic underpinning for this
association," said lead author Lauren Teras from American Cancer Society.
The researchers analysed data from women and men enrolled in
the American Cancer Society Cancer Prevention Study-II Nutrition Cohort.
Among 138,003 participants, there were 2,532 cases of
hematologic cancers identified between 1992 and 2009. The researchers found a
strong, positive association with paternal age among participants without
siblings.
In that group, those whose fathers were aged 35 years or
older at the time of their birth were at 63 percent higher risk of hematologic
malignancies compared to those whose fathers were younger than 25.
The study points to the need for further research to better
understand the association between paternal age at birth and hematologic
malignancies.
The study appeared in the American Journal of Epidemiology.

80 million births and deaths in world go undocumented every year
London: Scientists have found that as
many as 40 million new births and 40 million deaths in
the world are undocumented every year.
University of Melbourne
Laureate Professor Alan Lopez, one of the lead authors, has been leading a
global campaign to improve how countries capture civil registration and vital
statistics (CRVS). The four-paper series promote the case to change CRVS
systems to collect more reliable and timely data.
Lopez said that policy should be informed by accurate and
timely data, as poor quality data equals to poor decisions, which in turn leads
to lost opportunities to improve population health.
In remote areas where there are no doctors, CRVS improvements
could include family members of deceased responding to a limited number of
questions about symptoms experienced by the deceased which an algorithm using
big data samples would then analyse to record a most-likely cause of death,
Professor he said.
He said other technology advances could also be exploited
such as using mobile phones to transmit information about recent cases of
births and deaths, as "mobile phones are now common virtually
everywhere".
The first Lancet series paper looks at the current landscape
of CVRS. It highlights inconsistent recordkeeping worldwide, and argues for
marked improvements in order to gather better statistics to help policy makers
make better decisions. The second paper makes the case that good CRVS data is
not only required for informing health policies, but that it is also actually
good for health. In the third paper, the authors monitor the development of
existing CRVS systems and its limited growth.
The concluding paper presents a research and development
agenda for CRVS and challenges global health and development agencies to ensure
that every birth and death is registered, and every decision-maker has
detailed, continuous and locally relevant information needed to support policy
and planning.
The study is published in The Lancet.
