SummaryA major cause for the disparity in maternal and infant mortality and morbidity between the developing world and industrialized nations is the uncontrolled population growth seen in the former, largely brought about by failure of authorities to realize the importance of fertility regulation. Some governments and international agencies have introduced family planning programmes which have had a striking effect on the health of mothers and children. This study traces demographic changes in Singapore in the context of legislation disincentives and incentives.

SummaryIn a comparison of present and past users of contraceptive implants (Norplant) or injectables (DMPA) and discontinuers of Norplant or DMPA, information concerning the women's knowledge and perception of, and attitude to, implants and injectable contraceptives, was studied. The long duration of action (5 years) of implants was perceived positively by all groups as compared to the shorter 3-month duration of injectables, though this was seen as an advantage over the pill. It appears that the Norplant system has potential for wider use in Singapore in the future.

Five social disincentive policies were implemented by the Singapore government in 1973 to augment its fertility reduction program. The policies involve increasing delivery charges in government hospitals, school admission priority for children, maternity leave, priority in allocation of government housing, and income tax relief. In a two-year prospective study, 1,010 married abortees (study group) and 943 married parturients (comparison group) were questioned to determine their awareness and understanding of these policies, and whether the policies influenced their decision concerning their present pregnancies or would influence future decisions. Except for the tax policy, these disincentives were known to a fairly large proportion of the women studied. Knowledge was positively related to education level. Four of the five disincentives have, to varying degrees, influenced the women's decisions concerning their present pregnancies and may do so in future pregnancies. The two most widely known and most influential disincentives are those affecting school admission priority and accouchement fees.

SummaryThe associations of social and behavioural factors on preterm birth in Singapore were studied using hospital maternity records of 20,723 consecutive singleton births between January 1986 and November 1991. The overall proportion of preterm births was 3·6%, the rates for the Chinese, Malay and Indian groups being 3·2%, 3·8% and 4·9% respectively. Teenage mothers were at a higher risk of preterm labour compared to women aged 20–29 years. The incidence of preterm labour decreased with increasing educational status. Preterm births were six times more likely in women who had no antenatal care. Women who had three or more previous births were at a higher risk, while those who had one or two previous births were at a lower risk compared to women who had none.

SummaryA retrospective study of 21,442 Singaporean women who gave birth at the National University Hospital, Singapore, between January 1986 and November 1991 is used to assess the effects of increasing age on obstetric performance. The results show that reproduction after the age of 35 years in Singapore is associated with a higher incidence of antenatal complications such as hypertension and diabetes and a higher rate of obstetric intervention. However, given the current level of obstetric and neonatal care in Singapore, these adverse features do not prejudice the obstetric and neonatal outcomes.

SummaryThe influence of ethnicity on obstetric performance in Singapore was assessed by retrospective analysis of all deliveries in the National University Hospital over a 7-year period. Malay mothers were younger, shorter, less educated, of higher parity, were more likely to have had no antenatal care, and had the highest incidence of premature labour. However, mothers of Indian origin had the smallest babies, the highest incidence of low birth weight and significantly higher perinatal mortality rates. Chinese mothers fared better than their Malay and Indian counterparts in all parameters assessed. The ethnic origin of the mother has an important bearing on perinatal performance. This emphasises the importance of designing appropriate strategies to improve perinatal health in the different ethnic groups.
