Integration of family planning and maternal and child health in rural West Africa
Authors: Neumann Alfred K. , Ofosu-Amaah Samuel , Ampofo Daniel A. , Nicholas David D. , Asante Rexford O. 
Published: July 2008

SummaryThere is controversy extending beyond that of whether family planning or population control measures should be promoted among various populations. Even when the decision has been made to provide family planning advice, information and service, debate often arises as to the best method of administering a family planning programme—whether to integrate it with maternal and child health (MCH) services, offer it post-partum, or provide it independently of all other health activities.The Danfa Comprehensive Rural Health and Family Planning Project, Ghana, is investigating the general problem of health service delivery, including family planning, and is doing so with a firm commitment to efficient management, staff training and supervisory maintenance. An established research design and ongoing evaluation efforts, including cost and functional analyses, are an integral part of the project. While it is believed that the integrated MCH/Family Planning approach will yield optimal results in family planning acceptance (as well as reduction in morbidity and mortality), other alternatives of health care and family planning service delivery are being evaluated.
The zygosity of twins: further evidence on the agreement between diagnosis by blood groups and written questionnaires
Authors: Kasriel Judith , Eaves Lindon 
Published: July 2008

SummaryThe agreement between zygosity diagnosis in twins by reference to the twins' own answers to written questions and diagnosis based on an objective assessment of zygosity by blood-typing is studied for 178 pairs of same sex twins. Seventy-two female and 106 male twin pairs answered two questions concerning their similarity in appearance and frequency of confusion in childhood, and were blood-grouped using up to 23 different antisera. Of those pairs concordant for all markers and diagnosed as MZ, 98% agreed that they were confused in childhood and that they are alike in physical appearance. Only 55% of those pairs discordant for at least one marker and classified as DZ agreed that they were never confused and are not alike in appearance. The replies of the remaining 45% are spread over all the other combinations of responses. If all twins who agree that they were confused in childhood and are alike in appearance were to be classified as MZ on the basis of the questionnaire alone, and all others as DZ, the diagnoses of only seven pairs out of the total 178 (3–9%) would disagree with those based on blood group data.
Demographic and contraceptive innovators: a study of transitional African society
Authors: Caldwell J. C , Caldwell Pat 
Published: July 2008

SummaryData are employed from six surveys carried out in Ibadan City, Nigeria, during two survey programmes: the Nigerian segment of the Changing African Family Project in 1973, and the Nigerian Family Study in 1974–5. A distinction is made between contraceptive innovators, those who use any means to control fertility except the traditional Yoruba sexual abstinence, and demographic innovators, those who succeed in limiting their family size. It is shown that contraceptive innovation is now proceeding rapidly but has little connection with demographic innovation. Contraceptive innovation is a response to social change which has increased the likelihood of premarital and extramarital sexual relations and the desire to shorten the period of postnatal sexual abstinence while not increasing the interval between births. Such innovation has proceeded more rapidly because of the increased availability of contraceptives since about 1960 and because of the types of contraceptives which have been developed since then. Demographic innovation is on the increase but its incidence is still minute. Fertility restriction within marriages seems to take place only after profound changes have occurred in the economic relationships within both the extended and nuclear families which for the first time make the small family the economically rational choice. Such change probably depends more on the import of cultural patterns than on necessary cultural adjustments to imported economic change, but a strengthening of the conjugal bond is involved and this may be hastened by contraceptive innovation. Little innovational trauma or even awareness of profound change was detected, largely because the profound, and even disruptive, innovations are preceding social ones, but partly too because peer group behaviour changes at much the same time.
The artifactual nature of effects of maternal age on risk of stillbirth
Authors: Resseguie Laurence J. 
Published: July 2008

SummaryAnalysis of stillbirth data from the State of Wisconsin demonstrates that the association of stillbirth rate with mother's age is basically an artifact of analysis rather than a reflection of genuine effects of age on risk. When births to mothers of a single parity are subdivided according to the amount of education completed by the mother, the association between stillbirth rate and maternal age in each educational group differs substantially from the others. The association observed for all births of a single parity is inapplicable to any educational subdivision of the data.It is argued that the associations which are observed are the consequence of social forces which distribute women of varying intrinsic risk of stillbirth unevenly among age–parity categories.
Spacing of children and changing patterns of childbearing
Authors: Young Christabel M. 
Published: July 2008

SummaryThe first part of the paper traces changes in the length of the childbearing period and ages of women at the time of their first and last births among women in Australia married between 1905–09 and 1965–69. The source of information was survey data concerning the respondents themselves (once married, currently married women aged under 60 years at 1971) and information that they gave concerning their mothers' childbearing experience. The main observations are that the trend towards smaller families was more marked among the mothers and that the change in the size distribution of families was the major factor in reducing the length of the childbearing period for marriages occurring up to the Second World War, while closer spacing of children was the major factor since then. The second part of the paper examines more detailed supplementary information about the respondents, including changes in the dispersion of the timing of births, the rapid rate of childbearing among the 1955–59 marriage cohort, reasons for delaying the first birth, and differences in behaviour according to education and religion. The discussion raises the question of the rationality of the trend towards closer spacing of children, with special reference to the interaction between a woman's work role and family role.
A note on the future demographic structure of the coloured population of Birmingham, England
Authors: Woods R. I. 
Published: July 2008

SummaryThe combination of results from the 1971 Population Census and data specific to Birmingham make it possible to revise past estimates of the numbers of coloured persons in Great Britain. Such information also permits projections of the relative age structures of the coloured and total populations of Birmingham under differing fertility assumptions and Thomas's (1970) conclusions may therefore be revised.
Psychological factors in IUD use—a review
Authors: Reading A. E. , Newton J. R. 
Published: July 2008

SummaryThe high variability between centres in the incidence of side effects related to intrauterine devices (IUDs) is taken to indicate the need to direct research attention towards the context in which IUDs are inserted, as opposed to exclusive concern with the nature of the device. This paper considers the significance of psychological factors at the time of insertion in the light of recent studies indicating the benefits of adequate patient preparation.
Matrimonial migration: a review, with special reference to India
Authors: Pratim Manjumder Partha 
Published: July 2008

SummaryThe study of the distribution of matrimonial distances is extremely important in the understanding of human population structure. The existing models of matrimonial migration are reviewed here. An assessment of the roles played by various social, cultural, economic, religious and linguistic factors in shaping the distribution of matrimonial distances has been made, with special reference to India.
Effectiveness of contraception in Belgium: results of the Second National Fertility Survey, 1971 (NEGO II)
Authors: Cliquet R. L. , Schoenmaeckers R. , Klinkenborg L. 
Published: July 2008

SummaryThe percentage of accidental pregnancies, the Pearl pregnancy rate and the life-table method have all been used to study the effectiveness of contraception in Belgium, using data from the Second National Fertility Survey (1971), which covered 3397 Belgian women in the age group 30–34 years. Though all three methods yield generally similar results, it is only by using the third method that we can obtain in an optimum way changes in contraceptive effectiveness by birth order and birth interval.Generally, contraceptive effectiveness is low, the cumulative failure rate for the first 12 months of all intervals amounting to 18%. This holds even for intrinsically extremely reliable methods, such as the pill (4%). The efficiency of contraception, however, improves with increasing duration of marriage. This is attributable not only to a shift towards more effective methods, but also to a better application of less reliable methods, such as withdrawal. It remains questionable whether the increase in effectiveness, especially of a method such as withdrawal, is not partially based on induced abortion.The findings also clearly reveal the dual aspect of the contraceptive behaviour in the sample: spacing until desired family size is achieved, and prevention thereafter.The efficiency of contraception decreases with increasing family size, whatever birth interval is considered.
Factors affecting the incidence of Down syndrome in Scotland
Authors: Holloway Susan , Emery Alan E. H. 
Published: July 2008

SummaryThe incidence of Down syndrome in Scotland between 1960 and 1974 was estimated using data from thirteen Area Health Boards. Incidences in individual years, in different months of the year and in different maternal age groups were also determined. There was an apparent increase in incidence in more recent years almost certainly due to increased ascertainment. This may have obscured any decrease in incidence which might be expected as a result of a decrease in mean maternal age during this period and the introduction of antenatal diagnosis. No seasonal differences in incidence could be detected either in the whole area or in individual Area Health Boards. There was an increase in incidence with maternal age which was not significantly different from that found by other investigators. There was also an indication of an increase in relative incidence (% Down syndrome births/% live births) over the period 1966–74 in mothers aged 35 years and older.
Birth spacing and prolonged lactation in rural Zambia
Authors: Wenlock R. W. 
Published: July 2008

SummaryData were collected from 1044 mothers resident in the rural areas of Zambia during a National Nutrition Status Survey, to determine the effect of lactation on the interval between conceptions. Lactation is very prolonged with a small proportion of mothers continuing up to 33 months. A main reason for cessation of breast-feeding appears to be a new pregnancy, only 1.5% of mothers being neither pregnant nor lactating up to 12 months. During lactation, conception is delayed for at least 12 months. The peak in new conceptions occurs between 25 and 27 months. The normal interval between births is 3 years for rural Zambian mothers.
Social Identity and Genetic Variability
Authors: Cartwright R. A. , Hargreaves H. J. , Sunderland E. 
Published: July 2008

SummaryThe paper presents the results of five polymorphic systems in a sample of 999 individuals from Nottinghamshire. The results are classified by the socio-economic grouping of parents and self.The results show that social class differences for the genetic attributes exist and are almost linear when aggregated distances are computed. There are differences, however, between parental and offspring results. These differences may be the result of changes in social class over the last generation. This social mobility is investigated and it is shown that an upward movement in social class is associated with characteristic genotype groupings.
The Fourth Korean Child: The Effect of Son Preference on Subsequent Fertility
Authors: Park Chai Bin 
Published: July 2008

SummaryThis article, based on retrospective survey data, examines the fertility performance of third-order parity women in Korea, following births of specified sexes of children already born. Although the study indicates that additional births and spacing of children after the third birth are strongly influenced by the sex composition of the first three children, this influence becomes apparent only after the introduction of a vigorous national family planning programme. It seems that both the number of sons and the sequence of sons and daughters play an important role in determining subsequent fertility. More than twice as great a proportion of third-parity women proceeded to the fourth parity if the women had three daughters rather than three sons.
Problems of pre-natal screening programme for Down's syndrome in older women
Authors: Duncan Sheila L. B. 
Published: July 2008

SummaryThere is currently both an absolute and relative reduction in births to older women. In a single hospital population the number of older women. In a single hospital population the number of older women having amniocentesis for pre-natal diagnosis is only a small, though increasing, proportion of those at risk. The main factors in failure of offering amniocentesis are late booking and communication difficulty.
Social mobility and IQ components
Authors: Mascie-Taylor C. G. Nicholas , Gibson John B. 
Published: July 2008

SummaryThis study examines the relationship between verbal, performance and total IQ scores and social class of 193 male householders living in a Cambridge suburb. The correlation coefficients between IQ scores and present occupational status were significantly higher than the correlations between IQ scores and social class of origin, suggesting that intragenerational social mobility is positively related to IQ.Parent–offspring data were available for 85 father–son pairs. Analysis of the IQ differences between fathers and sons in relation to their social class differences provided further evidence for selective migration related to both IQ components and total IQ scores. In this sample there was a simple relationship between the extent of social mobility and the degree of difference between the father's and son's IQ scores.
Talking about children: an examination of accounts about reproduction and family life
Authors: Payne Judy 
Published: July 2008

SummaryThis study explores the reasons which individuals give for initially wanting children; data are drawn from intensive interviews concerned with reproduction, marriage and family life which were conducted with couples in the childbearing stage of marriage. The study is an extension of the approach but forward by Busfield (1974) in that it examines the beliefs which structure social constructions of reproduction.The evidence suggests that, although wide-ranging beliefs are drawn upon in accounting for wanting children, the underlying reasons are concerned with beliefs about the nature of ordinary adult life. However, except at a very general level, such beliefs are not uniformly held but are selected and structured by the particular situation and experience of individuals. The approach demonstrates how a deeper understanding of reproductive behaviour can be gained by relating it to the wider context of family, marriage and adult life.
Sensation seeking and gonadal hormones
Authors: Daitzman Reid J. , Zuckerman Marvin , Sammelwitz Paul , Ganjam Venkataseshu 
Published: July 2008

SummaryTwo samples of male students (N = 25, and N = 51) and a small sample of female students (N = 7) were administered the Sensation Seeking Scale (SSS), and blood samples were drawn on two occasions to determine plasma levels of androgens and oestrogens. Reliable and significant simple and partial correlations were found between the sex hormones and the SSS subscale, Disinhibition. Partial correlations simultaneously controlled for height, weight, age, and recency of orgasm.
Incidence of ovulatory cycles in women approaching the menopause
Authors: Metcalf Mary G. 
Published: July 2008

SummaryUrine was collected at weekly intervals at weekly intervals for three or more months from 139 menstruant women aged 40–55 years. Menstrual cycles were classed as ovulatory if the 24-hr pregnanediol output was > 5 μmol on a single occasion, or if the total excreted on 2 days 1 week apart was > 7 μmol. Of the 81 women who reported no change in menstrual frequency, 95% ovulated in every cycle. Only 34% of the 53 with a recent history of oligomenorrhoea ovulated without fail. Ovalation occurred in 93% of all 21–35-day menstrual cycles, in 55% of 36–50-day cycles, in 40% of 51–75-day cycles and in 17% of those lasting > 76 days. Pregnanediol increases suggestive of ovulation and followed by menstruation were observed on 31 occasions after amenorrhoea of from 2 to 6 months' duration.
The cost per unit of family planning services
Authors: Robinson Warren C. 
Published: July 2008

SummaryThis paper presents results of a cross-sectional analysis of family planning programme costs per unit for a group of 28 countries. The costs per unit are analysed using regression techniques with variables of programme (age, scale and type of programme) and setting (demographic structure, socio-economic level of development, health, accessibility and other). The Couple-Years of Protection Index is used for standardization and the variation in personnel costs among the countries is allowed for. There is considerable variation among programmes in cost per unit. Some of this variation is explained by differences in socio-economic structure. The cost per unit, measured in US $, is considerably higher than is generally thought.
The timing of post-partum menstruation and breast feeding: a simple formula
Authors: Billewicz W. Z. 
Published: July 2008

SummaryA function is proposed for estimating the proportion of women who resumed menstruation at a given time post-partum on the basis of the proportion of women breast feeding at that time. The function was fitted to 25 series of incidences from nine countries (236 time points), most countries providing three contrasting groups: urban (well-to-do), urban (poor) and rural. The average error of the estimate within series was 0·08. At any given time post-partum variation in breast feeding proportions [explained] on average 85% of between series variance in the proportions of menstruating women. Some uses of the function are briefly considered.
Resumption of menstruation among urban post-partum women in Bangladesh
Authors: Swenson Ingrid 
Published: July 2008

SummaryHalf the women in this study had resumed menses by the 6th month post-partum. Concurrent with these findings, less than 50% were still breast-feeding at the 6th month post-partum. The majority of these breast-feeding women were partially breast-feeding. By the 6th post-partum month more than 90% of the women had resumed intercourse and slightly less than half were using contraceptives. Nevertheless, the cross-sectional data indicate that only 25% of the women were using contraceptives at 12 months post-partum. These results show a much shorter period of lactational amenorrhoea than has been reported for a rural area of Bangladesh.
An estimate of the effect of abortions on the stillbirth rate
Authors: Gandy R. J. 
Published: July 2008

SummaryConsideration is given to the impact of the change in the Abortion Laws in 1968 on the national stillbirth rate. From investigation of the demographic characteristics of women having abortions it appears that abortions accounted for at least 26% of the fall in the stillbirth rate from 1969 to 1974.
Legalized abortion in South Australia: The first 7 years' experience
Authors: Yusuf Farhat , Briggs Dora 
Published: July 2008

SummaryThis paper examines the official abortion statistics for South Australia since the legalization of abortion in January 1970. The incidence of abortion is shown to be increasing steadily—in 1976 more than half of the extramarital pregnancies were terminated and the overall ratio of abortions to live births was nearly 1:6. Most abortion patients were single, young women. Comparison of fertility levels in South Australia with the rest of Australia shows that the fertility decline has been much more rapid in South Australia, suggesting that unless the South Australian women are more efficient users of contraception than other Australian women, a significant proportion of the fertility decline in South Australia has to be attributed to legalized abortion.
Genetic disease and culture patterns in Lebanon
Authors: Basson P. M. 
Published: July 2008

SummaryCases of βthalassaemia and haemophilia (factor 8 and 9 deficiency) in pre-war Lebanon were examined for social and genetic information, using medical records. All diagnosed cases admitted to the American University Hospital in Beirut between 1960 and 1970 were examined. Muslims and families of lower socioeconomic status predominated in the data, and many cases were located in the semi-rural poverty belt of Beirut, where many rural migrants and Palestinian refugees congregate. Parental consanguinity rates among male haemophiliacs were used as estimates for the general population. Consanguinity is higher in the thalassaemic population. In the Christian population the incidence of this autosomal recessive disorder appears to have been inflated by consanguinity more than in the Muslims
The effect on birth weight of employment during pregnancy
Authors: Gofin Jaime 
Published: July 2008

SummaryA study of employment during pregnancy and its effects was carried out among pregnant women who were under the care of the Community Health Center, Hadassah Medical School, in a neighbourhood of West Jerusalem. Of the women, 46−2% worked during pregnancy, and 78−6% of them were in occupations which demanded light physical activity. Most of the women worked throughout the whole pregnancy. Educational level as well as parity emerged as the main factors in determining whether a pregnant woman worked or not. No significant effects of employment were found in pregnancy complications or length of gestation, but significant differences did emerge in the number of delivery abnormalities. This finding is interpreted as the result of the interaction of several social conditions rather than of work itself. The findings support the hypothesis that work by itself does not affect either pregnancy or its outcome (as measured by birth weight).
