On population control see letters in BMJ
303 (1991), 1547. A paper on the effectiveness of breast feeding as a contraceptive
is in Lancet 339: 227-30. It was found to have a similar level of efficacy to most
modern contraceptives. A review on the topic of the safety of contraceptives is

56: 799-819.
The annual
UN Population Fund
report has predicted that until the year 2000, the world population will increase
by 97 million a year. They presented three scenarios for world population by the
year 2150; 1) 28 billion, if current fertility rates continue, with some countries
having high fertility rates; 11.6 billion if the fertility rate falls to where couples replace
themselves only; and 8.5 billion if low fertility rates become worldwide. The UN
Conference on the Environment and Development dropped the population issue, under
pressure from groups such as the Vatican, Argentina and the Phillipines, but there are
still calls for its inclusion as there should be.
The results of opinion surveys (from 1982) conducted in Sri Lanka on the factors involved
in women desiring contraception is W.I. de Silva, "Relationships of desire for no
more children and socioeconomic and demographic factors in Sri Lankan women", J. Biosocial Science
24: 185-99. Some of the factors involved were education and religion. Other studies
on
contraceptive use
are H.H. Akhter & S. Ahmed, "Determinants of contraceptive continuation in rural
Bangladesh", J. Biosocial Science
24: 261-8; O. Fakeye, "Reproductive characteristics and contraceptive method choices
of Nigerian women requesting terminal fertility control", Int. J. Fertility

The latest excuse for a ban on the use of the contraceptive pill in
Japan
is that it could enhance the spread of HIV; BMJ
304: 863. Earlier this year the Ministry of Health and Welfare had announced that
the pill would be introduced, after continual rejection. It is ironic, that until
very recently HIV has been poorly discussed in Japan, not being seen as a threat.
At least we can expect more discussion of HIV and prevention measures which is welcome.
It is also not surprising that they reversed their decision following government
concern about a falling birth rate among Japanese (the government recently introduced
guidelines for paid postnatal leave for either woman or man for up to a year from their
work, though some companies already have three year periods, and the amount of money
varies). Of course, these are not valid reasons for preventing people use of the
contraceptive pill, and the
Japan Family Planning Association
will continue to attempt to introduce oral contraceptives to Japan. Some background
on Japanese public opinion is in Studies in Family Planning
22 (1991), 378-83. In contrast to this approach, an AMA approach to encourage birth
control is "Requirements or incentives by government for the use of long-acting contraceptives",
JAMA
267: 1818-21. A new service in Nagoya, Japan, is a postal pregnancy service where
urine test strips are sent out to requesters via post. In the first three months
of this year they had requests from women from 14 years, with about 10% being women
in their 50's.

maternity services
in developing countries see Lancet
339: 487. There are still concerns in Britain over the maternal death rate; Lancet

Rumania
the abortion rate is now about three times the birth rate, due to economic conditions
(about 1 in 6 women of child-bearing age had an abortion last year).
RU-486
use is being debated in Germany, and Hoechst wants to market it there; NS
(28 March 1991), 18. There was meant to be a single abortion law in Germany from the
start of this year, but there are still differences and debate. The use of RU-486
and medical issues of its use for abortions in Britain are discussed in BMJ
304: 914. The debate in Australia is discussed in Search
23 (Jan/Feb 1992), 10-11.
Although not related to birth control, the performance of female circumcision in Europe
by Africans is reported in BMJ
304: 1134.
The use of compulsory contraception in court cases is debated in Lancet
339: 1104-1105, we need to protect people's reproductive rights, and also ensure
that people are free to use contraceptives and receive cost coverage.

up to 1990, from 200,000 to 90,000 abortions performed; Conscience
XIII, 37-8. After two years of financial pressure which stopped condom import, the

80: 226-33. A book review is in NS
(27 June 1992), 44. The results of a Schering Health Care company public survey in August
1990 found that only 10% of all women in the UK knew that post-coital contraception

on natural family planning is in Lancet
340: 309. In the US, the FDA committee has voted to approve Depro-Provera, a long-acting
injectable contraceptive; Science
256: 1754. It was actually recommended to be approved in the mid-1970's, but doubts
over safety led to this long delay.

Asia
, including Japan, China, Thailand, Korea (N&S) has already reached the level of replacement
only; Lancet

such an impact. The need for behaviour change for family planning is discussed in
SSM
35: 1065-76. The WHO maternal mortality figures suggest there are 500,000 maternal

FDA for use and sale in the USA. In the UK it was approved 8 years ago, but it is
still used by only 1% of the women who use contraceptives (compared to 5% who use the IUD,
and most who use the pill). To use this contraceptive, an injection is required
every 12 weeks. It is basically a progesterone (the male hormone) mimic. The needs
of women and various alternatives for contraception are considered in A.P. Hardon, "The
needs of women versus the interests of family planning personnel, policy-makers and
researchers: conflicting views on safety and acceptability of contraceptives", SSM

being enforced in
Tibet
by the
Chinese
government; BMJ
305: 911.
The lack of international government action on population control is criticised in
Nature
362: 379; NS
(3 April 1993), 4. The population is expected to reach 8 billion by the year 2025. Modern
contraceptives have decreased family size in average however, NS

Chinese product. Reasons for the lack of contraceptive research are discussed in
SA
(April 1993), 8-10.
On overpopulation and overconsumption see BMJ
306: 1185-6. A mathematical model of the predicted life history of the human race
is in Nature
363: 315-9. They predict a history of 0.2 - 8 million years, and that we won't populate
the galaxy. However, such calculations may depend more on politics than on scientific
potential! The birth rate in Japan now averages 1.% births per woman per life, similar to Germany (Italy is lower with 1.3 children per woman). Papers from China
suggest that in the 1960's about 40 million people died of starvation, which may
explain why they continue the one child per family policy.
In
India
some intrauterine contraceptive devices (
IUCDs
) have been said to be defective, Lancet

China
has prohibited the manufacture of a steel ring
IUD
in favour of the modern copper ring IUD, which is 6 times less likely to fail; NS
(17 July 1993), 11. This may reduce the approx. 3 million abortions performed annually
on women who use the steel IUD. Data from surveys of sexual activity and contraception
