Age at first marriage and fertility in rural Anhui, China
Authors: Yang Quanhe 
Published: July 2008

SummaryThis paper examines the changing nuptiality pattern of rural China, particularly rural Anhui in relation to the planned social changes since 1949 and their effect on fertility. The data are from the 1/1000 Fertility Survey of China, conducted by the Family Planning Commission in 1982. Before the family planning programme was introduced to rural Anhui (1972), the changing nuptiality pattern was indirectly affected by the planned social changes; after 1972, the substantial increase in age at first marriage was mainly due to the family planning programme. More recently, the centrally controlled social structure is loosening, due to the economic reform and the nuptiality pattern seems to join the 1972 trend, suggesting that the dramatic change of nuptiality pattern during the early 1970s to early 1980s was a temporary one. But its effect on fertility is clear, and the shortening interval between marriage and first birth may bring difficulties for future population control in rural China.
Trends in perinatal mortality attributed to congenital malformations in England and Wales during 1974–81: a study of the variations among regional Health Authority areas
Authors: Somchiwong Malinee 
Published: July 2008

SummaryAnalysis of perinatal mortality attributed to congenital malformations in England and Wales, using data from birth and death registration over the years 1974–81 showed significant declines in England and Wales as a whole and in the individual Regional Health Authority (RHA) areas. A greater decrease in death rate from congenital malformations, particularly central nervous system malformations, was seen among stillbirths than among early neonatal deaths. There were marked regional differences in perinatal mortality due to central nervous system malformations over the period but not in cardiovascular system malformations or in other malformations. The highest mortality rates due to central nervous system malformations occurred in the North, North-West, West and South-West of England and in Wales, and the lowest rates in the South and South-East. The larger percentage reductions in the mortality rates were found in most of the regions which had had the highest rates. Possible explanations for the decline in regional rates are suggested.
Post-partum events and fertility control in Kinshasa, Zaïre
Authors: Bertrand Jane T. , Chirhamolekwa C. , Djunghu B. , Chibalonza K. , Mahama K. 
Published: July 2008

SummaryContraceptive prevalence surveys from sub-Saharan Africa typically show low rates of method use. The current study of one zone in Kinshasa, Zaïre, provides a more detailed view of fertility control in an urban population by examining the relative duration of breast-feeding, amenor-rhoea and sexual abstinence during the post-partum period. While motivations to prevent pregnancy remain high until the youngest child is over 24 months, the average duration of abstinence is only 4 months. This paper describes the methods women use to avoid pregnancy and the changes over the post-partum period.
Seasonality of births among Bedouin Arabs residing in the Negev Desert of Israel
Authors: Guptill K. , Berendes H. , Forman M. R. , Chang D. , Sarov B. , Naggan L. , Hundt G. L. 
Published: July 2008

SummaryFrom 1 January 1981 to 31 December 1982 information on all births to Bedouin Arab women residing in the Negev Desert of Israel showed a previously unreported seasonal pattern. The peak season, November-February, coincided with the period of cool temperatures and the Bedouin Arab cultural seasons of winter and spring. This pattern is different from those of Jewish and Christian groups in the same region, a difference not attributable to religion alone.Sociodemographic factors associated with the peak season of birth include traditional occupations of fathers, multiparae 2+, and traditional place of residence. This pattern has persisted over the past 15 years although it is less apparent among the more recently sedentarized Bedouin Arabs.
Time to pregnancy—a model and its application
Authors: Boldsen Jesper L. , Schaumburg Inger 
Published: July 2008

SummaryBiological fertility is poorly measured by the number of children born in industrially advanced societies. The time elapsing from when a couple decides to have a child to clinically recognizable pregnancy is a useful alternative. Time to pregnancy can be collected in broad categories in large samples. A model for condensing important information from such data is presented, which fits several large samples of reported waiting times. It is shown that multiparous women conceive more quickly than primiparous women.
Contraceptive social marketing in Nepal: consumer and retailer knowledge, needs and experience
Authors: Shrestha Ashoke , Kane Thomas T. , Hamal Hem 
Published: July 2008

SummaryIn 1986, a survey was conducted to assess knowledge, health concerns and experience with marketing (retailers) and use (consumers) of Gulaf and Nilocon pills and Kamal vaginal tablets distributed by the Nepal Contraceptive Retail Sales Company (CRS). A sample of 763 consumers of Gulaf, Nilocon and Indian pills and Kamal vaginal tablets, and 361 retailers from a stratified sample of urban medical shops were interviewed. The CRS marketing programme is reaching people who have previously never used family planning; most of the users were practising contraception to limit, not space, births; a high proportion of pill users over 35 smoked; only about a third of CRS pill users had prescriptions or consulted a physician prior to use; CRS training of retailers was found to have increased their knowledge. Recommendations are made for improving communication, education and marketing of CRS contraceptives to ensure their safe and effective use and increase the acceptability of this mode of service delivery.
A Study of infant mortality and causes of death in a rural north-east Brazilian community
Authors: Bailey Patricia , Tsui Amy Ong , Janowitz Barbara , Dominik Rosalie , Araujo Lorena 
Published: July 2008

SummaryIn 1984 a prospective study of 1645 women and 1677 births in a rural community in north-eastern Brazil showed the infant mortality rate to be 65 per 1000 live births. Neonatal, post-neonatal and infant mortality are analysed to determine the most important risk factors for each period. Post-neonatal survival depends largely on factors relating to child care, while neonatal deaths are more likely to be associated with biological factors. The principal cause of death, diarrhoeal disease, was responsible for a third of the deaths.
Child mortality levels and survival patterns from Southern Sudan
Authors: Roth Eric A. , Kurup K. Balan 
Published: July 2008

SummaryData from a 1985 survey in two major population centres in Southern Sudan, Juba and Wau, were analysed in order to assess childhood mortality levels and the effect of UNICEF's health care programme. There are continuing high levels of childhood mortality. Logistic regression analysis shows significant positive associations between child survival and immunization, oral rehydration therapy and maternal education.
Predicting contraceptive method usage among women in West Scotland
Authors: Hunt Kate , Annandale Ellen 
Published: July 2008

SummaryUsers of the six major methods of contraception are compared across a broad range of variables using data from a community sample. Differences between the groups were apparent for a range of socioeconomic and reproductive variables, and current users of the various methods also differed in their past use of contraception. Users of barrier methods fared particularly well. Few differences were observed for current health status or for the sociocultural variables examined, although users of natural methods differed from all others in their religious affiliation and commitment.Discriminant analysis showed that the most predictive variables distinguishing women who had opted for permanent methods of contraception (female sterilization and vasectomy) were the woman's stated reason for using her current method and her past contraceptive patterns; the inclusion of social, health and reproductive indicators did little to improve the prediction. It is argued that heightened expectations for contraceptive efficacy in the face of increasing concerns about long-term health consequences have contributed to the increased use of permanent methods.
Divorce in contemporary Japan
Authors: Fukurai Hiroshi , Alston Jon 
Published: July 2008

SummaryData from the 1985–86 Japanese census are analysed to explore the determinants of the divorce rates in Japan's forty-seven prefectures, using two theoretical models: (a) the social integration model, which is shown to have a greater utility in predicting Japanese divorce levels than (b), the human capital model. Female emigration patterns play a significant role in affecting the divorce rate. Population increase and net household income are also important predictors of the Japanese divorce rate and urbanization has a great influence in modern Japan. Demographic and aggregate variables such as migration, urbanization, and socioeconomic factors are useful when organized under a social integration model.
Fertility preferences among Malaysian women: an analysis of responses to the new population policy
Authors: Khor Geok Lin 
Published: July 2008

SummaryAbout 10% of 3887 ever-married women included in the 1984–85 Malaysian Population and Family Survey revealed that they were influenced by the new population policy to desire more children than they had originally wanted. These women were more likely to be rural Malays from the lower socioeconomic class. Ideal family size was more than four children. Children are desired for economic benefits and emotional support. The natality of the Malays has risen since 1980: their total fertility rate has increased while their contraceptive prevalence rate has dropped sharply. Coupled with a decline in the crude death rate, the present fertility preferences and behaviour of the Malays will render the target of the population policy more attainable than is reflected by the survey data.
Socioeconomic structure and fertility in China: a county level investigation
Authors: Poston Dudley L. , Zhongke Jia 
Published: July 2008

SummaryAnalysis of the general fertility rate in the counties of China shows significant associations with infant mortality, illiteracy, and the percentage of the population employed in industry, but not with industrial or agricultural output. Urban counties differ from rural in the importance of the illiteracy rate. The associations in the rural counties vary according to the region of China in which they are located.
Social class as a risk factor for infant mortality in an Australian population
Authors: Quine Susan 
Published: July 2008

SummaryStudies in other countries have identified social class as a risk factor for infant mortality. In Australia there is no systematic collection of population data by social class, partly due to the absence of a recognized measure. The use of occupational prestige as an indicator of social class is discussed and Australian prestige scales reviewed. In a population based study, logistic regression analysis of infant mortality in an Australian (NSW) population shows the effects of social class on infant mortality which remain when maternal age, marital status and parity are controlled.
Changes in contraceptive use and fertility: El Salvador, 1978–88
Authors: Monteith Richard S. , Warren Charles W. , Caceres Jose Mario , Goldberg Howard I. 
Published: July 2008

SummaryIn El Salvador from 1978 to 1988, contraceptive use among married women 15–44 years of age increased from 34% to 47%, and the total fertility rate declined from 6·3 to 4·6 children per woman. Most of this change took place from 1978 to 1985. Sterilization is the most prevalent method used, but nearly one-half of the women who are sterilized did not use any contraception before their operation. Few young couples use reversible methods of contraception to space births or delay the start of childbearing. On average, women wait 8 years after marriage and have nearly three children before they use contraception.
Lactation, birth spacing and maternal work-loads among two castes in rural Nepal
Authors: Panter-Brick Catherine 
Published: July 2008

SummaryThe nursing behaviour of rural Nepali women, from two castes inhabiting the same village, is quantified on the basis of 2202 hr of continuous and direct day-time observation over 1 year. Feed duration, interval, total time and daily frequency are examined in relation to women's work, particularly the type of subsistence activity and seasonality. ‘Opportunity’ feeds are governed both by infant demands and maternal activity. Caste differences in birth intervals are also discussed.
Socioeconomic and cultural differentials in age at marriage and the effect on fertility in Nepal
Authors: Aryal Ram Hari 
Published: July 2008

SummaryAge at marriage is one of the factors that influence the fertility behaviour of women, particularly in a society like Nepal where contraceptive use is low. Socioeconomic and cultural factors, particularly religion and ethnicity, are important variables in determining age at marriage in Nepal. Fertility was negatively related with age at marriage. Marriage duration had a greater influence on fertility than age at marriage, although these were strongly correlated.
An ‘epidemic’ model of adolescent sexual intercourse: applications to national survey data
Authors: Rowe David C. , Rodgers Joseph L. 
Published: July 2008

SummaryThis paper applies models of the onset of adolescent sexual intercourse using national data from Denmark and the USA. The model gave excellent fits to data on Danish Whites and a good fit to American Whites, but the model-fits for American Blacks and Hispanics were not as good. The weakness of the latter model fits may reflect either real processes that the model does not capture or problems in the reliability of adolescent sexuality data.
Effects of socioeconomic factors on secular trends in suicide in Japan, 1953–86
Authors: Motohashi Y. 
Published: July 2008

SummaryThe effects of socioeconomic factors on secular trends in suicide rates in Japan for the periods 1953–72 and 1973–86 were investigated using twelve socioeconomic indicators. Multiple regression analysis showed that the socioeconomic indicators affecting suicide rates were not identical in the two periods. The rates in both sexes in 1953–72 were closely related to unemployment rate and the labour force but between 1973 and 1986, divorce rate and the proportion in tertiary industry were most influential. The changes reflect the socioeconomic changes in industrial structure in Japan in transition from an industrial to a service economy.
Breast-feeding, birth interval and child mortality in Bangladesh
Authors: Majumder Abul Kashem 
Published: July 2008

SummaryThe 1975–76 Bangladesh Fertility Survey data show little evidence that breast-feeding is the intermediate factor through which birth intervals influence child survival in Bangladesh. Preceding birth interval, subsequent pregnancy and breast-feeding duration each have an independent influence on early mortality risk. Within a specific interval the risk of dying decreases with increase in duration of breast-feeding, and also with an increase in the time between the index birth and the next pregnancy. The death of the immediately preceding child in infancy has a significant negative effect on the survival chance of the index child at ages 1–5 months. However, death of the preceding child appears to have a significantly positive effect on the survival chance of the index child between ages 9 months and 5 years; this may be related to competition between siblings.
Proximate determinants of child mortality in liberia
Authors: Ahmad Omar B. , Eberstein Isaac W. , Sly David F. 
Published: July 2008

SummaryThe study looks at the effects of maternal sociodemographic characteristics and the quality of the environment on child survival through two intervening variables, breast-feeding and prenatal care. A linear structural equation modelling approach was used to examine infant and child survival based on a weighted sample of 5180 Liberian children aged 0–5 years. The findings confirm previous studies, but also reveal complex relationships of the role of education, maternal age and breast-feeding in enhancing child survival.
Education, fertility and contraception among Hindus and Roman Catholics in Goa
Authors: Roy T. K. , Rao G. Rama , Prasad Rajiva 
Published: July 2008

SummaryDifferences in age at marriage, fertility and contraceptive use are related to religious background, individual educational level and community level education. In general, the effects of community education are weak compared to individual level of education, but differences exist between Hindus and Roman Catholics.
Fertility levels and trends in Arsi and Shoa regions of Central Ethiopia
Authors: Hailemariam Assefa 
Published: July 2008

SummaryLevels and trends of fertility in the Arsi and Shoa regions of Central Ethiopia are examined, using data from the 1986 Population, Health and Nutrition baseline survey of the Ministry of Health of Ethiopia. The population has high fertility. Total fertility of six children per woman in the late 1960s increased to eight children per woman in the early 1980s, then declined to seven children per woman in the mid-1980s. Urban fertility declined by a substantial amount during the 15 years before the survey while rural fertility increased during the same period.The implications of high fertility are considered.
Birthweight and sociobiological factors in Ilorin, Nigeria
Authors: Ebomoyi Ehigie , Adetoro Olalekan O. , Wickremasinghe Ananda R. 
Published: July 2008

SummarySocial and biological factors influencing birthweight of 3053 Ilorin babies were studied. The mean birth weights were 2·998 kg ±0·133 (SD) for males and 2·932 kg ± 0.154 (SD) for females. Multiple regression analysis showed that maternal weight, height, age, education and ethnicity, and child's sex, significantly affected birthweight of infants. Some quadratic and interaction terms also contributed significantly to the prediction of birthweight. The strategies to control the incidence of low birth weight are discussed.
Infecundity and subfertility among the rural population of Ethiopia
Authors: Tesfaghiorghis Habtemariam 
Published: July 2008

SummaryA 1980–81 survey of the rural population of Ethiopia found high levels of infecundity and subfertility, although there was considerable variation by region, ethnicity and age of women. Higher levels of infecundity were geographically concentrated in a broad belt that ran from the south and south-west of the country, across to the north-east. The analyses suggest that infecundity is influenced by ecological factors, more than by ethnicity.
Family environment and cognitive correlates of young adults' social status attainment: ethnic group differences
Authors: Marjoribanks Kevin 
Published: July 2008

SummaryA longitudinal sample of 21-year-old Australians from Anglo-Australian, Greek and Southern Italian families was used to examine relationships of children's cognitive performance, family learning environments, adolescents' perceptions of family learning contexts, and measures of young adults' social status attainment. Generally, the findings using a regression approach indicated that there were ethnic group differences in the relations between parents' academic socialisation, children's cognitive performance, and measures of young adults' social status attainment. The results also showed that in each ethnic group, adolescents' perceptions of parents' support for learning had strong associations with young adults' status attainment.
Season of birth and recalled age at menarche
Authors: Boldsen Jesper L. 
Published: July 2008

SummaryAll 8th-form schoolgirls from the municipality of Odense in Denmark were asked at what age they reached menarche, and 886 girls (97·6%) gave this information. There is no evidence for seasonality in the time of birth but for far more girls than expected menarche occurred during winter or summer and fewer than expected during spring and autumn. This pattern appears primarily in girls living in the suburbs and was not seen in those living in central Odense. The seasonality appears to be brought about by differences in mean age at menarche according to time of the year at birth.
Biosocial variances and infant survival: a path analysis approach
Authors: Frisch Ann Stirling , Kallen David J. , Griffore Robert J. , Dolanski Eugene A. 
Published: July 2008

SummaryThis study used path analysis to assess the chances of survival of babies in a neonatal intensive care unit in Lansing, Michigan, USA. Two paths to neonatal survival were identified and the variables accounted for 20% of the variance in gestational age. The first path showed that prior infant losses were negatively correlated with gestational age while in the second path, gestational age showed negative relationships with pre-pregnancy weight and household job worries.
Extending lactational amenorrhoea in Manila: a successful breast-feeding education programme
Authors: Benitez Isidro , de la Cruz Julieta , Suplido Azucena , Oblepias Virgilio , Kennedy Kathy , Visness Cynthia 
Published: July 2008

SummaryAn experimental breast-feeding education programme conducted at the Philippine General Hospital in Manila demonstrated that women could be motivated to improve their breast-feeding practices and lengthen their period of lactational amenorrhoea in comparison to a control group. Mothers who participated in the programme breast-fed their babies more frequently, delayed the introduction of regular supplements, used fewer bottles and pacifiers and maintained night feeding longer than mothers who were not exposed to the positive breast-feeding messages. The programme was successful in lengthening the period of amenorrhoea among women with elementary, high school, or technical school education, but not among college-educated women. Different educational approaches may be necessary for women of different education levels.
Normative study of age variation in salivary progesterone profiles
Authors: Lipson S. F. , Ellison P. T. 
Published: July 2008

SummaryDaily luteal progesterone levels were measured for 124 regularly menstruating women, aged 18–44, by radioimmunoassay of steroid levels in saliva. A consistent pattern of age variation in luteal function was found, with the lowest levels of progesterone in the 18–19-year-old and 40–44-year-old groups, the highest values in the 25–34 year olds, and intermediate values in the 20–24 and 35–39-year-old groups. The striking similarity of this pattern of age variation with empirically and theoretically generated curves of apparent fecundability, suggests that age-related changes in ovarian function may underlie observed age variation in fecundability.
Infant and child mortality in rural Egypt
Authors: Casterline John B. , Cooksey Elizabeth C. , Ismail Abdel Fattah 
Published: July 2008

SummaryThis research examines determinants of infant and child mortality in rural Egypt, primarily the effects of household economic status and the availability of health services. Certain features of the health service environment affect survival in the neonatal period. In early childhood, survival chances improve markedly as income increases and if the household depends almost exclusively on employment income. In infancy and in early childhood, mortality is strongly associated with region of residence and maternal demographic characteristics, and is weakly associated with parental schooling.
