Not all pregnant women give birth to viable babies, however. Out of every 100 pregnancies, one baby is either stillborn or dies in the week following delivery (CBS, 1994). Moreover, more than 10% of all the officially registered pregnancies, result in an involuntary loss of the baby before the 16th week of gestation (Nederlands Huisartsen Genootschap, 1989). Comparable percentages are reported in other Western countries (Borg & Lasker, 1988; Keirse, 1989; Pfeffer & Woollet, 1985). Since miscarriages are not all registered, the exact occurance remains unclear. Indeed, even less conservative estimates would seem to indicate that percentages actually surpass 15 to 20% (Oakley, McPherson & Roberts, 1984/1985; Scott, 1990), suggesting that miscarriage is a rather common experience, affecting at least 19,500 families in The Netherlands each year. Adding this figure to the almost 2,000 families that are confronted with the death of their baby around the normal time of delivery, means that involuntary pregnancy loss is experienced by approximately 21,000 families each year. The frequency with which pregnancy loss occurs, stands in sharp contrast to the amount of attention it received until recenüy. It took until the seventies for social and medical science to realize that pregnancy loss had been the poor relation of research (Bourne, 1968; Keirse, 1989; Kirk, 1984; Kirkley-Best & Kellner, 1982; Kirkley-Best & VanDevere, 1986; Lewis & Page, 1978).

This introduction presents an overview of the 'state of the art' of pregnancy loss research. After giving the definitions and causes of pregnancy loss, this chapter will proceed to discuss the consequences of pregnancy loss for parents and siblings, and reviews the results of research into psychosocial risk factors for a problematic outcome. Some questions that still remain unanswered are presented, followed by a description of the design of a new study, the results of which will be presented in subsequent chapters. Definitions and causes of pregnancy loss Involuntary pregnancy loss is defined in several ways, each referring to the length of pregnancy and the developmental stage of the foetus at the time of the loss. The definitions vary from country to country (Keirse, 1989; Peppers & Knapp, 1980a). In The Netherlands, the term miscarriage or spontaneous abortion refers to a loss before the 16th week of gestation (Nederlands Huisartsen Genootschap, 1989), as opposed to international literature where it is frequently used to refer to a loss up to the first 20 weeks (Scott, 1990), or 28 weeks (Oakley et al., 1984/1985). The term fetal death or stillbirth refers to the death of a baby shortly before or at the time of delivery, irrespective of pregnancy length if this had exceeded at least 20 weeks (Kochenour, 1990) or 28 weeks, or if the birthweight is over 1000 grams (Keirse, 1989).
