这个报告稀里糊涂。

The Union of Myanmar, Ministry of
Immigration and Population,
Department of Population has released
the preliminary report of the Myanmar
Fertility and Reproductive Health
Survey carried out in 2001. This report
is intended to provide timely and brief
information on fertility, contraception,
maternal and child health, infant and
child mortality, knowledge of STDs
and HIV/AIDS and internal migration.
The report finds that the total fertility
rate in Myanmar has dropped to 2.4
children per woman, showing a
continuous decline from 2.9 children
per woman in 1991 and 2.7 in 1997.
While fertility of urban women has
fallen well below the replacement level
(1.8 children per woman), rural women
still tend to have somewhat high
fertility, at 2.6 children. The increase in
the proportion of women remaining
single has been identified as the prime
determinant of fertility decline,
according to the report. Other key
determinants include contraceptive use,
high rate of abortion/foetal wastage and
long duration of breast-feeding.
Some 37 per cent of currently
married women of reproductive age
were found to be currently using any
method of contraception, with an
overwhelming majority (33 per cent)
using modern methods. The injection
was the most prevalent method used by
15 per cent of currently married
women, closely followed by the pill (9
per cent) and female sterilization (5 per
cent). While the intrauterine device
(IUD) and male sterilization were used
by 1.9 and 1.3 per cent of women or
their husbands, respectively, the use of
condoms was negligible.
The survey revealed that the per -
cent age of pregnancies receiving ante -
natal care from nurses and mid wives
reached 63 per cent in 2001, a signifi -
cant rise from 50 per cent in 1991. On
the contrary, the per cent age of pregnan
cies receiving care from traditional
birth at tendants was reduced by half,
from 14 per cent in 1991 to 7 per cent in
2001. While 57 per cent of the deliver -
ies were at tended by health profession -
als (doc tors and nurses/mid wives), a
sizable pro portion of the deliveries
were at tended by traditional birth at ten -
dants (39 per cent). The survey also in -
dicated that a majority of the deliveries
took place at home (83 per cent) while
14 per cent of the deliveries occurred at
hospital.
