Determinants Of Cumulative Fertility In Ghana

The relatively few studies conducted on fertility differentials in Ghana have not controlled for the effect of important demographic variables, such as age at first marriage and current age of respondent. This paper attempts a multivariate analysis of the relationship between cumulative fertility and age at first marriage, level of education, religion, form of marriage and residence of husband. Data drawn from a census sample survey in 1971 include 72,816 currently married females aged 15–49 years. Age at first marriage was inversely related to cumulative fertility. The differentials were more pronounced for older women. Among the older women, the differentials were larger for rural than urban women. There were also significant fertility differentials associated with level of education, religion and form of marriage. Husband’s residence was a poor predictor of cumulative fertility. As a policy measure, it is suggested that priority be given to providing young women with more education or employment opportunities as an alternative to early marriage.     

Social determinants of low birth weight in a high-risk population

Over ninety low-weight infants were born per thousand live births in South Carolina, based on 96,000 birth records from 1975 and 1979. Higher incidence of low birth weight for black infants cannot be explained away as a result of black/white differences in age or education of mothers, prenatal care, parity or length of birth intervals. Though all these factors are important predictors of birth weight, an increasing propensity to have low-weight babies persists among black mothers even after all these factors are controlled.     

On place utility and the normative allocation of intra-urban migrants

This paper arises out of the fact that place utility, a basic factor in behavioral conceptualizations of migration processes, has not been specified in operational terms. This is done here through a model that assigns intraurban migrants to destination areal units within the city, using a normative linear programming framework based on behavioral considerations. Measures of place utilities for each areal unit and of comparative place utilities for each pair-wise permutation of areal units are provided by the shadow prices of the dual of the linear programming model. The primal of the model allocates migrants so as to maximize the household’s gain from migration. This is measured by the increase in its realized aspirations with respect to a residence site, tempered by the search effort involved in acquiring the site. Implementation of the model utilizes both questionnaire and published data from Cedar Rapids, Iowa for the year 1966 to 1967. Conformity between predictions of the model and real-world characteristics is such that it is concluded that the basic form of the model is sound. It is also concluded that the posited relationships between place utility and behavior in searching for and selecting a new residential site are reasonable and can lead to valuable insights into place utility and its functioning in the intra-urban system. Due to some misallocation of migrant flows, however, we further conclude that the model should be revised into a recursive format for future use.     

Dynamics of contraceptive use and breastfeeding during the post-partum period in Peru and Indonesia

This paper examines the interaction between contraceptive use and breastfeeding in relation to resumption of intercourse and duration of amenorrhea post-partum. We used data from the month-by-month calendar of reproductive events from Demographic and Health Surveys (DHS) in Peru and Indonesia. The analyses show that breastfeeding women were less likely than non-breastfeeding women to have resumed sexual intercourse in the early months post-partum in both countries. In Peru, but not in Indonesia, breastfeeding women had a significantly lower odds than non-breastfeeding women of adopting contraception. Although the likelihood of contraceptive adoption was highest in the month women resumed menstruation in both countries, about ten per cent of subsequent pregnancies occurred to women before they resumed menses. These results emphasize the importance of integrating breastfeeding counselling and family planning services in programmes serving post-partum women, as a means of enabling those who wish to space their next birth to avoid exposure to the risk of a pregnancy that may precede the return of menses.     

Why does the need for medication become a barrier to breastfeeding? A narrative review

Problem

The need for medication during lactation can contribute to the early cessation of breastfeeding.

Quality of Life Predictors and Normative Data

This study identifies predictors and normative data for quality of life (QOL) in a sample of Portuguese adults from general population. A cross-sectional correlational study was undertaken with two hundred and fifty-five (N = 255) individuals from Portuguese general population (mean age 43 years, range 25–84 years; 148 females, 107 males). Participants completed the European Portuguese version of the World Health Organization Quality of Life short-form instrument and the European Portuguese version of the Center for Epidemiologic Studies Depression Scale. Demographic information was also collected. Portuguese adults reported their QOL as good. The physical, psychological and environmental domains predicted 44 % of the variance of QOL. The strongest predictor was the physical domain and the weakest was social relationships. Age, educational level, socioeconomic status and emotional status were significantly correlated with QOL and explained 25 % of the variance of QOL. The strongest predictor of QOL was emotional status followed by education and age. QOL was significantly different according to: marital status; living place (mainland or islands); type of cohabitants; occupation; health. The sample of adults from general Portuguese population reported high levels of QOL. The life domain that better explained QOL was the physical domain. Among other variables, emotional status best predicted QOL. Further variables influenced overall QOL. These findings inform our understanding on adults from Portuguese general population QOL and can be helpful for researchers and practitioners using this assessment tool to compare their results with normative data.     

Factors affecting intention to breastfeed of a group of Brazilian childbearing women

Background

Knowing the intention of mothers is important to plan actions to improve exclusive breastfeeding rates.

Factors influencing the casefinding of migrations in the Liberian fertility survey

A study was made of the factors that affected the casefinding of internal migrations in Liberia using the Chandrasekar—Deming dual enumeration and tabulation methods. The results of this work suggest that the recording and not recording of a migration is not a random occurrence but is associated with a particular enumeration system, origin and destination of the migration, and the migrant’s age, sex, and location of current residence.     

Prospective study of birth interval dynamics in rural Bangladesh

A group of 209 married, fecund women in rural Bangladesh were studied prospectively for 24 months from 1969 to 1971 to define some of the biological and sociological factors relating to fertility performance. These women were selected from a larger study population of 112,000 that had been followed with a daily house-to-house vital registration programme since 1966. The selected women were interviewed bi-weekly and were asked questions about menstruation, pregnancy, lactation, husband's occupational absences, and monthly urine tests for pregnancy were taken. The results for 193 non-contracepting women revealed that the seasonal pattern of births previously observed in this population could be associated with a corresponding seasonal pattern of conceptions and that this was due to a seasonal trend in fecundability. The highest conception rates were in the coolest months of the year. Post-partum lactational amenorrhoea was very prolonged, averaging 17 months for women with a surviving child. The appearance of the first post-partum menstrual flow (onset of ovulation) also had a seasonal trend which could not be adequately explained. The median waiting time to conception, once menstruation had resumed was eight months. This interval was influenced by seasonal fluctuations, as well as by the age of women and by husbands' absences. The foetal wastage rate was 15·0 per 100 conceptions, with 62 per cent of the foetal losses occurring during the second month of gestation. Overall, the average birth interval was 33 months, with the prolonged lactational amenorrhoea accounting for almost 45 per cent of this interval.      

Health-Related Quality of Life of Chinese Earthquake Survivors: A Case Study of Five Hard-Hit Disaster Counties in Sichuan

As one of the most destructive natural disasters, earthquakes affect the health of survivors. The devastating earthquakes that hit Sichuan, China have aroused the concern of domestic and international scholars. The health-related quality of life (HRQOL) of survivors also requires substantial research. Studies on impact factors, such as gender, age, monthly income, and education, have become controversial. The subjects in this study are the people of five hard-hit disaster counties in Sichuan Province, namely, Wenchuan, Qingchuan, Mianzhu, Lushan, and Dujiangyan. A preliminary survey was conducted in May and June 2013 in areas badly hit by the earthquake in Sichuan, China. A total of 2000 questionnaires were distributed, and 1672 of which were received, yielding a recovery rate of 83.6 %. To further complement and corroborate the conclusions, a follow-up survey was conducted in October and November 2013, where 1526 effective questionnaires were received. The analysis in this paper is mainly based on the first survey, and the collected data from the follow-up survey were used to perform a supplementary analysis. By analyzing data from five hard-hit areas in Sichuan and by establishing models, we drew the following conclusions: The results of analysis of variance and Tukey’s honestly significant difference tests revealed the following results. First, the results of two investigations indicate the HRQOL of earthquake survivors is relatively poor, especially in terms of general health (GH), mental health (MH), social functioning (SF), etc. However, results of the second survey indicate that the scores of all domains (except GH) have increased significantly, with the SF having the most significant increase. Second, the HRQOL scores of men are higher than those of women. Individuals with higher education or monthly income have higher HRQOL scores than those with lower education or income. Moreover, younger survivors have higher HRQOL scores than older survivors. Third, a positive correlation exists among the HRQOL domains of all survivors. Among all domains, the PF, RP, GH, MH, and VT of survivors have a very strong correlation. In addition, SF, BP, MH, and VT have a strong correlation. Other variables have a relatively weak correlation.     

New money,and old man/lady and ‘Two's company’: Subjective Welfare in the NORC General Social Surveys, 1972–1982

The nine surveys, dozens of variables, and more than ten thousand cases in the NORC General Social Surveys, 1972–1982, allow one to test a variety of cross-sectional and over-time hypotheses about Subjective Welfare (Happiness). I used discrete multivariate analyses to test five hypotheses: (1) the Economist's prediction that Happiness is a function of income; the Sociologist's hypotheses that Happiness is a function of (2) rank on various evaluated dimensions and (3) number of social ties; and the Psychologist's hypotheses that Happiness is affected by (4) social comparisons and (5) adaptation. None of the five is supported impressively, but three variables emerge as good cross-sectional predictors — Race (Blacks are less Happy, but not necessarily because of discrimination), Marital Status (all categories of nonmarried are less happy) and Financial Change (those whose finances are improving are happier, those who finances have turned for the worse are less happy). When Marital Status and Recent Financial Change are used in a year-to-year social indicator model, fluctuations in the predictors produce significant but small changes in Happiness.     

The effects of breastfeeding and pace of childbearing on mortality at early ages

The effects of the pace of childbearing and breastfeeding practices on infant mortality have rarely been considered together. In this paper, we design and use a set of methodological tools to test a variety of hypotheses postulating the effects of breastfeeding and pace of childbearing on mortality in infancy and early childhood, the mechanisms through which those effects operate, and the contingencies that strengthen or weaken them. The strong effects of both length of breastfeeding and the pace of childbearing on the risks of child death suggest that neither of them exerts an impact on mortality totally mediated by the other. Social and demographic factors (such as age of child, education of mother, and region of residence) also condition the impact of breastfeeding and pace of childbearing on mortality.     

Rurality and well-being during the middle years of life

Popular stereotypes and theorizing by social scientists suggest that rural people are more satisfied with their communities and happier with their life situations than are their nonrural counterparts. This enhanced well-being is believed to result at least partly from the presence of kinship and friendship ties in the local community and the adherence to traditional religious beliefs. Data from a panel study of nearly 1200 middle aged persons from Pennsylvania surveyed in 1971 and 1984 provided indices of community satisfaction and happiness. When income was controlled, country residents expressed slightly higher levels of community satisfaction than did town or urban dwellers in both time periods. Happiness was not related to residence location. Income was a relatively more important predictor of community satisfaction and happiness among urban than among country residents, while number of friends was relatively more important for rural residents. Number of kin living nearby and adherence to traditional religious beliefs were not related to well-being regardless of residence location.     

Social indicators and spatial disparities in Papua New Guinea

This study attempts to identify and classify the 87 districts of Papua New Guinea by their levels of development. With the aid of factor analysis applied to 30 elementary indicators, six major dimensions or features associated with development are uncovered. The factor scores of the more important features (education status, urbanization, nutrition status) are mapped. Various measures are used to compute the overall status of a district. Next cluster analysis is used to classify districts on the basis of their similarity on certain combinations of attributes. Comments are made on the agricultural and urban sectors in the context of Papua New Guinea's first 5-year National Development Plan. A set of possible planning regions comprising the less developed districts is suggested.     

An evaluation of brass mortality estimates under conditions of declining mortality

An evaluation of the Brass childhood mortality estimates under conditions of declining mortality shows them to overestimate current mortality. Error increases as the rate of mortality decline increases, as the childhood age up to which cumulative mortality is being estimated increases, and as age at onset of childbearing decreases. We use the results to develop a method for correcting the Brass estimates for the effects of quasistability. The method requires an estimate of the rate of mortality decline within the population in addition to information on the pattern of childbearing in the population.     

Urbanization and de-urbanization of the black population before the civil war

Pre-Civil War black urbanization is examined using data from federal census records, 1790 to 1860. The black population is found to be as urban as the white population initially, but its urbanization underwent relative decline in the last two decades before the Civil War. Foreshadowing current patterns, the northern black population was heavily concentrated in the largest cities, and the free black population was the most urban of all groups. The timing of black urban decline in the North, as well as regional and size of place differences in that decline, suggest that both competition with immigrants in major eastern seaboard cities and the passage of the Fugitive Slave Law in 1850 contributed to black de-urbanization. For the South, the explanations of black urban decline proposed by Wade, Conrad and Meyer, Goldin, and Bonacich are evaluated, and Bonacich’s split labor market theory is judged to be most consistent with the demographic trends.     

Impact of support networks for breastfeeding: A multicentre study

Background

The rates of breastfeeding worldwide are slowly improving since 1996. Europe is still trailing behind the global breastfeeding incidence and prevalence rates. Thus, breastfeeding promotion, protection, prolongation and support have become an important challenge as breastfeeding sharply decreases in the first six months of life.

Mediating Effects of Affect and Loneliness on the Relationship Between Core Self-evaluation and Life Satisfaction Among Two Groups of Chinese Adolescents

This study examined the mediating effects of affect (positive and negative affect) and loneliness on the relationship between core self-evaluations (CSE) and life satisfaction among two groups of Chinese adolescents. Three hundred adolescents (169 males and 131 females) from Shenzhen and Xi’an in China completed the Core Self-evaluations Scale, Positive and Negative Affect Scale, UCLA Loneliness and Satisfaction with Life Scale. Research revealed that positive and negative affect, and loneliness fully mediated the relationship between CSE and life satisfaction. The relationship between CSE and loneliness was partially mediated by positive and negative affect. Loneliness partially mediated the relation between positive and negative affect and life satisfaction. The final model also indicated two significant paths from CSE through positive and negative affect and loneliness to life satisfaction. Furthermore, a multi-group analysis found that the paths did not differ across gender. Limitations of the study are considered and implications of the results for enhancing adolescents’ life satisfaction are discussed.     

An investigation of the age of an alleged centenarian

At times, persons have been reported as living to extremely advanced ages such as 130, or even higher (McWhirter and McWhirter, 1977, p. 26; Medvedev, 1974; Merrill, 1976). However, controlled studies of closed groups like Civil War veterans (Myers and Shudde, 1955) have not shown any persons surviving beyond age 110, when age has been reasonably verified. It seems, therefore, highly plausible that reports of extremely advanced ages at death reflect exaggerations of age rather than reality. This note reports a case history which supports this view and illustrates how ages can be verified using available census data.
