The period total first abortion rate (TFAR) has been used to estimate the proportion of women who will experience an induced abortion in their reproductive lifetime. It is a hypothetical measure as age-specific rates currently existing will change with time. Instead, a cohort TFAR has been calculated for women born around 1955 using legal-abortion reports in South Australia to calculate first abortion rates for each year of age from 15 years to 44 years for 1971-2000, respectively, and summing these. Yearly fertility rates were also calculated for this cohort to further describe their reproductive experience. Yearly first abortion rates were also calculated for later cohorts born in 1960-1980. The 1955 cohort TFAR was 288.1 per 1,000 women aged 15-44 years. Cumulative first abortion rates at specific ages were higher for subsequent cohorts (e.g., 309.6 per 1,000 at age 40 years for the 1960 cohort). Thus, about 29% of South Australian women born around 1955 and exposed to legal abortion throughout their reproductive lifetime experienced an induced abortion. This proportion would be higher for later cohorts of women born in 1960-1980 (e.g., at least 31% for those born in 1960).

BACKGROUND: Until recently, premarital examination for both men and women was a legal requirement before marriage in China. Researchers have carried out surveys of attendees' sexual activity, pregnancy and abortion before their marriages, trying to map out reproductive health needs in China, according to this unique population-based data. To systematically identify, appraise and summarise all available studies documenting pregnancy and induced abortion among unmarried Chinese women attending premarital examinations. METHODS: We searched the Chinese Biomedical Literature Index from 1978 to 2002; PUBMED; and EMBASE. Trials were assessed and data extracted by two people independently. RESULTS: Nine studies, of which seven were conducted in the urban areas, one in the rural areas, and one in both urban and rural areas, met the inclusion criteria. In the seven studies in urban areas, the majority of unmarried women had experienced sexual intercourse, with estimates ranging from 54% to 82% in five studies. Estimates of a previous pregnancy ranged from 12% to 32%. Abortion rates were high, ranging between 11 to 55% in 8 studies reporting this, which exclude the one rural study. In the three studies reporting both pregnancy and abortion, most women who had become pregnant had an induced abortion (range 86% to 96%). One large rural study documented a lower low pregnancy rate (20%) and induced abortion rate (0.8%). CONCLUSIONS: There is a large unmet need for temporary methods of contraception in urban areas of China.
