Anthropometric indicators of nutritional status, socioeconomic factors and mortality in hospitalized children in Addis Ababa
Authors: Groenewold W. G. F. , Tilahun M. 
Published: July 2008

SummaryThe influence of some household and maternal variables on three anthropometric nutritional status indices of hospitalized children in Addis Ababa, Ethiopia, are examined. On admission, only 30% of these children can be classified as being of a normal overall nutritional status. There are no significant differences in weight-for-age of hospitalized children between those residing in Addis Ababa and those residing in the rural areas. Income and father's occupation appear to be the major household factors influencing the level of two of the three indices (weight-for-age and weight-for-height). Length of last closed birth interval and, to a lesser degree, maternal age appear to have significant effects on all three nutritional status indices. Upon admission to hospital, children who will in the end survive their hospital stay are on average nutritionally normal or in a mild state of malnutrition, whereas children who will die during their stay arrive in a moderate or severe state of malnutrition. The degree of malnutrition is positively related to the risk of mortality in respiratory disease patients.
Social class and human twinning
Authors: Bønnelykke Birgitte 
Published: July 2008

SummaryIn a comparative study to examine the effect of social factors on human twinning, data on sociodemographic and other factors were collected from parents of all twins born alive in Denmark in 1984 or 1985 and from a random sample of parents of singleton infants born in the same years. A postal questionnaire was used. The twins were classified as monozygotic (MZ) or dizygotic (DZ) twins by the similarity method. A trend was found in DZ-twinning, with significantly fewer DZ-twins born in the lower social classes, but not in MZ-twinning. All results were controlled for maternal age and parity.
Age at marriage in Sri Lanka: stabilizing or declining?
Authors: De Silva W. I. 
Published: July 2008

SummaryOver the last four decades in Sri Lanka, age at first marriage for males increased marginally, and for females it rose considerably, but there has been no recent increase in female age at marriage. Among the younger cohorts, estimated ages at which some married indeed show a declining mean age at marriage. Coale-McNeil estimates indicate that there is no real decline in female age at marriage in Sri Lanka. Marriages were delayed as a result of economie hardship or increased mortality to the mid-1970s, but once the overall economy improved after 1977, more marriages took place. Female age at marriage in Sri Lanka remained slightly below 24 years, the age which is anticipated by younger cohorts, and this level is likely to persist for some time.
Constraints on weaning: evidence from Ethiopia and Sudan
Authors: Almedom Astier M. , de Waal Alexander 
Published: July 2008

SummaryEvidence on infant weaning processes provided by field research in Addis Ababa, Ethiopia, and among a refugee population of Eritreans in the Sudan is presented. The study in Addis Ababa, where households were economically disadvantaged but the situation was nutritionally stable, allowed the identification of factors constraining weaning, which includes both the introduction of supplementary foods and the termination of breastfeeding. While the timing of each aspect of weaning was the outcome of the interaction between mother and infant factors, ‘infant-centred’ factors were more important in the commencement and ‘mother-centred’ factors in the completion of weaning. The refugee population had in normal times a similar weaning regime, but under the unstable conditions of flight and life in a refugee camp the process had been significantly altered. Investigation of the factors which have led to altered weaning processes elaborates and confirms the model derived from the Addis Ababa study.
Reproductive pattern in a rural Mediterranean population: La Alpujarra, Spain
Authors: Luna F. , Fuster V. 
Published: July 2008

SummaryThe reproductive pattern of a sample of nuclear families from La Alpujarra (Andalusia, Spain) is analysed. The origin of the wife or consanguinity of the couple does not influence fertility. Variability in number of pregnancies is most closely associated with marriage duration followed by the wife's year of birth. Differences in the number of births are explained more by the number of pregnancies than by the number of miscarriages. The number of survivors to the first birthday is dependent on the number of births and to a lower extent on infant mortality. Data from incomplete families show that reproductive performance of the wife below the age of 45 cannot be accepted as a reliable estimate of complete reproduction.
An evaluation of a national breast-feeding promotion programme in Honduras
Authors: Popkin Barry M. , Canahuati Judy , Bailey Patricia E. , O'Gara Chloe 
Published: July 2008

SummaryA significant increase occurred in the initiation and duration of breast-feeding among Honduran women between 1981 and 1987. Changes in population characteristics (e.g. level of education of women) would be expected to lead to a decrease in breast-feeding at each infant age, but these were offset by behavioural changes that led to an increase in the likelihood of initiation and continuation of breast-feeding. An exploration of relevant factors suggests that the PROALMA breast-feeding promotion programme has had a profound effect on the breast-feeding behaviour of Honduran mothers.
An estimation of inbreeding from isonymy in the historical (1734–1810) population of the Quebrada de Humahuaca (Jujuy, Argentina)
Authors: Dipierri Jose Edgardo , Ocampo Susana B. , Russo Armando 
Published: July 2008

SummaryThe method of isonymy to estimate inbreeding is applied to the historical population of the Quebrada de Humahuaca (Province de Jujuy, Republic of Argentina). Data from the baptismal records of the Parochial Church of Humahuaca from 1734 to 1810 were grouped into two periods, 1734–72 and 1773–1810. The analysis was carried out twice: (a) using the surnames exactly as they were registered; (b) combining homonymous surnames which were pronounced or spelt in a similar way. The random and non-random components of inbreeding have been investigated through different methods. There were no significant differences between the results of the two analyses, nor between the expected and observed isonymy. The value of Flies somewhere between those for offspring of first cousins once removed and second cousins once removed. There is a tendency for F and its components to increase through time. It is concluded that the high altitude aboriginal population of Humahuaca Parish must have behaved as a panmictic unit.
Size at birth and some sociodemographic factors in gypsies in Hungary
Authors: Joubert Kálmán 
Published: July 2008

SummaryIn 10,108 babies born to gypsy parents, birth weight, birth length and gestational age are compared with a national reference sample, taking into account maternal education, age, and birth interval. The gypsy babies tend consistently to be smaller, and this difference is attributable to the circumstances in which the gypsies live as well as the poorer maternal education. There appears to be a vicious circle—poor hygiene and living conditions adversely affect birth size, which in turn puts the child at a disadvantage in terms of survival, health and development.
A reversal of fertility trends in Singapore
Authors: Singh Kuldip , Fong Yoke Fai , Ratnam S.S. 
Published: July 2008

SummaryFree access to contraception and effective legislation measures, have resulted in a decline in fertility in Singapore. A new population policy of ‘three children or more if you can afford it’ was therefore introduced in 1986. This paper discusses the new population policies and measures their effect on fertility in Singapore.
Marriage trends in the Italo-Greeks of Italy
Authors: Biondi G. , Perrotti E. 
Published: July 2008

SummaryThe Italo-Greek ethnolinguistic minority, living in thirteen villages of southern Italy, marry largely amongst themselves but there are some intermarriages with native Italians. The majority of marriages are within the villages, but there is some marriage movement from one Italo-Greek village to another. Data on marriage and birthplace of parents and grandparents obtained by questionnaires to families of primary school children (aged 6–13 years) are analysed, to show the trends in breakdown of isolation over the last two generations.
Adult mortality from information on orphanhood and widowhood among the Kanuri of Nigeria
Authors: Udjo E. O. 
Published: July 2008

SummaryAlthough demographic information on Nigeria has increased in the past two decades, information on adult mortality in the country is still sparse. This paper provides information on the levels and trends in male and female adult mortality among the Kanuri of north-east Nigeria. Analysis of reports of orphanhood and widowhood suggests moderately high levels of mortality.
Intention versus behaviour in parental sex preferences among the Mukogodo of Kenya
Authors: Cronk Lee 
Published: July 2008

SummaryThe relationship between parents' stated sex preferences for children and actual parental behaviour towards sons and daughters is examined among the Mukogodo, a group of traditional pastoralists in rural Kenya. Although their cultural values are male-centred and they tend to express a preference for sons, Mukogodo parents actually appear to be more solicitous of daughters, and the Mukogodo have a strongly female-biased childhood sex ratio. Studies of stated sex preferences should therefore be coupled with attempts to assess actual parental investment in sons and daughters.
Relationships among given names in the Scilly Isles
Authors: Raspe Pamela , Lasker Gabriel 
Published: July 2008

SummaryThe pseudo-genetic analysis of given names shows that, in the Scilly Isles, coefficients of relationship of first names are similar on St Mary's, the Outer Isles, and in the total sample of 5666 individuals married there in two and a half centuries. Comparable coefficients of relationship of a sample of 1658 given names in marriages in England and Wales in 1975 are considerably smaller, but similar within and between districts. The coefficients of relationship of given names on the Scilly Isles decreased during the 19th and especially the 20th centuries in parallel with decreases in random relationship from surnames. The genetic versus cultural–linguistic factors cannot be distinguished in the temporal variation in names, but the geographic differentiation virtually always reported in surnames is not present in these examples of given names and the geographic pattern in the surnames thus seems to result from the hereditary aspect of surnames. This result supports the validity of use of surnames in models of human genetic geography.
Parental education and child mortality in Burundi
Authors: O'Toole Josephine , Wright Robert E. 
Published: July 2008

SummaryThis paper examines the relationship between parental education and child mortality in Burundi using data collected in the 1987 Demographic and Health Survey. Proportional hazards models are estimated to examine this relationship, while holding constant other known child mortality determinants. Parental education proves to be a key factor in explaining differences in child mortality, the effect of maternal education being particularly strong compared to paternal education.
Marital mobility within Shahrestan Nowshahr, Northern Iran
Authors: Mehrai Haideh , Sunderland Eric 
Published: July 2008

SummaryBirth localities of spouses from two generations are examined, to assess the extent to which the observed patterns of marital mobility link the spatially separated and kin-structured sub-populations within the ‘shahrestan’ of Nowshahr. The results indicate localised marriages and short range movements from the village of birth in both generations. Temporal increase in the range of movement indicates the breaking down of isolation, thus providing greater possibilities for admixture and genetic homogeneity.
Abortion in South Australia, 1971–86: an update
Authors: Yusuf Farhat , Briggs Dora 
Published: July 2008

SummaryOfficial statistics on abortion in South Australia for the period 1971–86 are analysed in terms of incidence, age of patients and nuptiality, reasons for abortion, method of termination, period of gestation, previous abortions and concurrent sterilisation. Demographic implications are discussed and recommendations are made for more education and counselling, especially for younger and unmarried women for whom the incidence of abortion seems to be rising.
Reaction times and intelligence: a comparison of Japanese and British children
Authors: Lynn Richard , Shigehisa T. 
Published: July 2008

SummaryJapanese and British 9-year-old children were compared on the standard progressive matrices and twelve reaction time parameters providing measures of simple and complex decision times, movement times and variabilities. The mean of the Japanese children on the progressive matrices exceeded that of the British children by 0·65 SD units and on the decision times component of reaction times by 0·50 SD units, suggesting that the high Japanese mean on psychometric intelligence is largely explicable in terms of the more efficient processing of information at the neurological level. Japanese children also showed faster movement times but, contrary to expectation, had greater variabilities than British children.
Effect of education and household characteristics on infant and child mortality in urban Nepal
Authors: Pant Prakash Dev 
Published: July 2008

SummaryInfant and child mortality differentials are analysed by education of parents and other family members, access to toilet, electricity and source of drinking water in urban Nepal, using data from the Nepal Fertility and Family Planning Survey, 1986. The analyses showed significant effects of education, access to toilet and electricity in lowering infant and child mortality. Access to toilet and electricity are proxies for house-hold socioeconomic status which suggests that education and household resources are complementary in lowering the infant and child mortality.
Matriarchy, polyandry, and fertility amongst the Mosuos in China
Authors: Johnson Nan E. , Zhang Kai-Ti 
Published: July 2008

SummaryA survey of 232 households of the Mosuo minority group in Yunnan Province, People's Republic of China, suggested that polyandrous matriarchy did not raise the birth rate per household, but lowered the community birth rate by restricting many women's chances of marrying. The results imply that tolerance by the national government of polyandry within certain minority groups (e.g. Mosuos and Tibetans) will not prevent but may aid the attainment of zero population growth by China in the twenty-first century.
Determinants of child-bearing intentions of low-income women: attitudes versus life circumstances
Authors: Radecki Stephen E. , Beckman Linda J. 
Published: July 2008

SummarySurveys of low-income women in Los Angeles County in 1985 and 1986 were used to examine the relative impact of child-bearing motivations versus life circumstances on the intention to have a(nother) child. Future child-bearing intentions are strongly related to current parity level regardless of marital status, race/ethnicity or economic status. Psychological motivating factors predict child-bearing intentions of nulliparous women, but not those of parous women. Multivariate analyses showed that motivation for parenthood and life circumstances combined predicted women's child-bearing intentions 88·6% of the time for nulliparous women, but 73·7% for parous women. These findings suggest that, in a low-income population, the onset of parenthood reduces the relationship between specific motivations for child-bearing and actual child-bearing intentions, and diminishes the ability to predict child-bearing intentions based on both attitudinal and social/structural factors.
Immunisation coverage in Lusaka, Zambia; implications of the social setting
Authors: Pillai Vijayan K. , Conaway Mark 
Published: July 2008

SummaryThis paper develops a conceptual framework for examining the process of immunisation and explores the sociodemographic determinants of vaccination in Zambia. About 300 mothers with children under 3 years of age were interviewed in urban Lusaka. The analyses suggest that sociostructural, as well as cultural, processes influence the attrition process and immunisation programmes should focus on the uniqueness of each stage. In addition, programmes to improve women's education and to reduce male gender preferences are needed.
Determinants of contraceptive continuation in rural Bangladesh
Authors: Akhter Halida H. , Ahmed Saifuddin 
Published: July 2008

SummaryA contraceptive study of rural Bangladeshi women indicated that the previous death of children, number of living children, desire for additional children and son preference were important determinants of contraceptive continuation. The importance of these factors varies to some extent with use of different contraceptive methods.
Maternal body composition: methods for measuring short-term changes
Authors: Norgan N. G. 
Published: July 2008

SummaryThe measurement of short-term changes in maternal body composition during the post-partum period under field conditions poses many problems: (1) body composition techniques depend on the constancy of the proportions of components or their physical properties and are less suitable for measuring changes; (2) many of the techniques require expensive, technically sophisticated apparatus that is inappropriate to field conditions in many countries; (3) changes in body composition affect some areas of the body more than others so regional as well as whole body approaches are required. The measurements of body weight, triceps and subscapular skinfold thicknesses and upper arm circumference are essential measurements. These can be supplemented with further skinfold thicknesses and circumferences, and possibly body density and body water measurements. There is little to be gained by transforming anthropometric variables into whole body composition indices in these circumstances.
Some determinants of population variation in cortisol levels in a British urban community
Authors: Pollard Tessa , Ungpakorn Giles , Harrison G. Ainsworth 
Published: July 2008

SummaryUrinary cortisol excretion rates were determined from three urine samples given over 2 days, a rest day and a working day, by 51 men and 50 women. Each subject also completed a questionnaire relating to life style factors and to perceived levels of stress, busyness and happiness on each day. In men, an association between raised cortisol and high levels of stress was found. In women, high levels of busyness were associated with low cortisol excretion rates. The subjective experiences measured accounted for around 10–20% of cortisol variation in this naturalistic setting.
Geographical distribution of some Danish surnames: reflections of social and natural selection
Authors: Boldsen Jesper L. 
Published: July 2008

SummaryGeographical differences in the frequencies of eight common surnames in Jutland (Denmark) are analysed using data from telephone directories of 121 exchanges. All the names showed a significant geographical surplus variance, which was divided into trend and patchiness components reflecting the history of the names. The surplus variance of surnames with restricted areas of origin was dominated by a large trend component; for surnames with an originally more even distribution, the patchiness component was dominant. The patterns of distribution were affected by processes which modelled natural selection with linkage disequilibrium. The combined patchiness within the clusters of exchanges gave information about patterns of local migration and level of social integration in the communities. Areas situated in boundary regions show high levels of patchiness.
Prevalence and determinants of caesarean section in Jamaica
Authors: Webster Linda A. , Daling Janet R. , McFarlane Carmen , Ashley Deanna , Warren Charles W. 
Published: July 2008

SummaryThe prevalence and determinants of primary caesarean section in Jamaica were estimated from a survey of women aged 14–49 years. Among 2328 women reporting 2395 live hospital births during the period January 1984 to May 1989, the prevalence of caesarean section was 4·1%. Repeat caesarean sections accounted for 1·3% of the hospital births during that period. Of the medical complications studied, prolonged labour and/or cephalopelvic disproportion carried the highest risks of primary caesarean section, followed by breech presentation, maternal diabetes, a high birth-weight baby, maternal hypertension, and a low birth-weight baby. The risk of primary caesarean section increased with maternal age, decreased with parity, was higher for urban than for rural residents, and was higher for births in private versus government hospitals.
Postpartum tubal sterilisation: an international perspective on some programmatic issues
Authors: Chi I-Cheng , Thapa Shyam 
Published: July 2008

SummaryThe demand for postpartum sterilisation (performed within 42 days after delivery), is increasing both in developed and developing countries. The incidence of regret after postpartum sterilisation is important, but it could be minimised by carefully screening risk factors. Using trained paramedical personnel to perform postpartum sterilisation via minilaparotomy where physicians are in short supply appears to be safe and acceptable, under close medical supervision. Including postpartum sterilisation information in the antenatal counselling services effectively strengthens postpartum services and simultaneously helps to minimise subsequent regret.
Determinants of low birthweight: a comparative study
Authors: Defo Barthelemy Kuate , Partin Melissa 
Published: July 2008

SummaryThe study compares biological, socioeconomic and behavioural determinants of low birthweight in Cameroon and the United States. Some factors in low birthweight are found to be cross-national, but others are specific to the setting. Positive risk factors of low birthweight in both countries include unmarried motherhood, female sex, multiple births, and preterm births. Outcome of the previous pregnancy is a positive risk factor in the US, but not in Cameroon. Significant negative risk factors include prenatal care visits (in both countries), mother's education (in the US only), births to mothers aged 20–34 and birth orders of 2 or more (in Cameroon only). Separate analyses of all births and the subsamples of singleton births reveal that estimates for the two groups differ only marginally.
Determinants of coitus after childbirth
Authors: Udry J. Richard , Deang Lionel 
Published: July 2008

SummaryUsing a sample of 3080 women from Cebu, Philippines, interviewed immediately after childbirth and every 2 months thereafter for 2 years, the determinants of return to coitus are analysed. Eighty percent of the women returned to coitus before the return of menses, and 90% did so before stopping breast-feeding. In hazards models, variables associated with traditional life styles retarded return to coitus. Situational variables (husband resident, crowding, children aged 6 and under), especially husband residence, and biological variables (mother's age, return to menses, and lactation) were significant predictors of return to coitus. The implications of the analysis for the construction of models of birth interval dynamics are discussed.
