Birth timing: supporting female graduate students

ABSTRACT Women seeking higher education frequently do so during peak childbearing years and women with higher levels of education are more likely to postpone motherhood until a later age. Fertility rate, defined as the average number of children born to a woman over her lifetime, has decreased globally. The decrease in birthrate has been partially attributed to women seeking educational opportunities. Understanding the experience of students in this realm would allow higher education institutions to better support students who are (or wish to be) mothers. Unfortunately, there is a paucity of research examining graduate women and the factors involved in their consideration of having a child while in school. We seek to fill this gap by examining the impact of fertility concerns (FC) and importance of on-time degree completion (DC) on the probability of having a biological child in graduate school (PC) among 469 female graduate psychology students in the USA. We found higher FC was associated with higher PC. In contrast, higher DC was associated with lower PC. Furthermore, FC had a significant unique relation to PC after accounting for the contribution of DC. We discuss how institutions and programs may help support and empower female graduate students by implementing educational policies and procedures that are supportive of graduate student mothers. This is particularly important because a large proportion of women pursue advanced degrees, and this number is projected to increase.

Multidimensional Analysis of Adolescent Fertility in Latin America: Trends and Determinants

Adolescent pregnancy in Latin America constitutes a complex issue with significant consequences. High pregnancy rates among individuals under 20 years old impact education, personal development, and future opportunities. It is imperative to pay closer attention to sexual education, access to contraceptive methods, and reproductive health services to prevent unintended pregnancies and ensure the well-being of both adolescents and their children. The study aimed to elucidate the determinants influencing the adolescent fertility rate, thus providing an academic contribution for the formulation of public policies in Latin America. The period covered was 1990-2019, and the analyzed data were sourced from the World Population Prospects 2019 report. The main findings indicate that the adolescent pregnancy rate is alarming, attributed to the absence of effective public policies for control and prevention in response to this phenomenon.   Received: 10 February 2024 / Accepted: 27 April 2024 / Published: 5 May 2024

The influence of personal political connectivity on fertility intentions across changing family planning policies in China

ABSTRACT In the past years, China’s fertility rate has experienced negative growth. In order to cope with the decline in fertility rate and the ageing of the population, the multi-child policy was implemented in 2015, that is, from the original husband and wife having only one child to having two or more children. Since the promulgation and implementation of China’s policy will have a greater impact on people’s livelihood, so before and after the implementation of the fertility policy, the impact of residents ’ political connectivity on fertility desire needs further study. This study categorizes residents’ political connectivity into political participation behaviour, political background, and political attitudes to explore the impact on residents’ fertility intentions. It conducts an empirical analysis of residents’ fertility intentions using data from the China General Social Survey (CGSS). The study found that before and after the implementation of the multi-child policy, there was a positive correlation between political participation behaviour and fertility intention, and there was no significant change. The influence of residents with party members ‘political background and residents’ political attitude on fertility intention has changed greatly, from negative correlation to positive correlation.

Aging with and into disability: An introductory review with clarification of basic terms

Aging involves the progression of becoming older, encompassing physical, mental, and social changes that take place in individuals over time. The longer lifespan and decreasing fertility rates have brought attention to the difficulties experienced by elderly people with disabilities. A survey method was used to collect titles of articles from different electronic databases, both online and offline, in national and international journals, as well as chapters or full-length books in the fields of gerontology and disability studies. The resulting list of 95 entries up to March 2024 was examined using the SANRA guidelines (Scale for the Assessment of Narrative Review Articles: Baethge, Goldbeck-Wood, & Mertens, 2019), aided by a flow chart and harvest plot to visually present the findings. The main focus was on clarifying fundamental terms related to aging with and into disability, successful aging, atypical aging, psychological aging, premature aging, and others. This type of clarification, which is not yet available from a single source, is considered necessary for aspiring researchers in this field to choose specific topics or themes for further study. The findings provide valuable insights for future considerations and opportunities for additional research.

PERIODISATION OF CHANGES IN STATE FAMILY POLICY IN POLAND BETWEEN 1989 AND 2022

The subject of this article is the periodization of changes in the state family policy in Poland that took place in the years 1989–2022, in order to systematize on this basis the main directions, priorities and instruments of the title policy as well as the most significant events, activities and turning points in a given area. This analysis shows a multi-aspect perspective on the assessment of the evolution of family policy in Poland in the years 1989–2022. Indicates, among others: periods in which there was a significant expansion of the scope of state intervention in the functioning of the family, especially through a significant increase in expenditure on financial instruments, for example after 2015. However, the development of service and leave instruments is particularly important, which took place in particular in 2013 as part of the "Good climate for the family" program. Due to the low fertility rate, financial difficulties of many families and difficulties in combining child care responsibilities with paid work, family policy should be based to a greater extent on investments and social services.

Health District at Queenstown: Catalyst for translational research

Ageing societies dominating global demographics is not new. However, the pace of global population ageing is causing disquietude. In 2017, the global population over age 60 years exceeded those below 5 years for the first time in history, and only 3 years later, the population over age 65 surpassed those below 5.1,2 The US took 72 years to double its proportion of population over age 65 from 7% to 14% while Sweden took 85 years, but Asia has been projected to achieve this in about 23 years, with Singapore having taken 20 years.3 This unprecedented ageing acceleration in populations results from longer individual lifespans due to improvements in healthcare and population health, combined with a steady decline in total fertility rate—the latter being the mean number of children per woman in her lifetime. Unfortunately, the number of years in good health has not kept pace with lengthening lifespan; consequently, time spent in poor health is increasing.4 This demographic change, along with a widening healthspan and lifespan gaps will have dramatic impact on economic growth, workforce composition, healthcare, housing and transportation.

Intensification of reproduction of a highly productive dairy cattle herd

The research work was carried out in a breeding facility for dairy cattle breeding with a milk yield per cow of 10,564 kg and a reproduction level of 96.6 %. Semen of Holstein bulls was used for reproduction. At dry-off pregnant cows were immunized against a range of bacterial, viral and parasitic diseases. After birth, the calves were injected with vitamin E and selenium, dectomax and gradually immunized against common infections. Data on 922 heifers were included in the analysis, including 192 obtained through inseminating cows with sexed semen. Heifers were inseminated at 13–15 months of age. Fertility rate after the first insemination was 67.4 %, calving at the age of (710 ± 2) days. Early calving and balanced feeding ensured high milk yields in full lactation and standard period – on average 9401 and 8854 kg of milk with the fat mass fraction of 4.32 %, protein of 3.38 % and the number of somatic cells of 73 thousand/ml. After calving, the first insemination was carried out on average in 82.6 days, the efficiency was 61.8 %, the insemination index was 1.60, the service period averaged to 107.5 days. When using sexed semen, the fertility rate after the 1st insemination was the same – 67.7 %. The age at calving in animals of the Vis Ideal line was 20 days more compared to their peers of the R. Sovereign line (722 versus 702 days, P < 0.05). Milk yield in full lactation and its standard period were higher in animals of the R. Sovereign line – 9304 and 8890 kg versus 8753 and 8461 kg, which indicates the positive effect of early calving on animal productivity. Early calving of heifers is a necessary condition for a highly productive herd. The results of the research are recommended to be used not only at dairy farms of the Republic of Belarus, but also in other countries with developing dairy cattle breeding.

This study uses the two forecasting methods to obtain images and compare them to enrich the population forecasting methods, which has great theoretical and research significance for the population development trend of the future society and the formulation of correct and reasonable population planning schemes.

Correlation Analysis Between National Fertility Rate and Socioeconomic Development: A Study Based on Birth Rates in China

China's declining fertility rate poses significant challenges to social and economic development. The deceleration in population growth, potentially leading to negative growth, has diverse implications. Socially, an aging population strains the social security system, escalating demands for healthcare and pensions, while insufficient supply may compromise social welfare. The labor market is also affected, as an aging populace may cause labor shortages and increased labor costs, impacting economic development. Economically, the fertility rate decline hampers economic growth by slowing down population and economic scale expansion. Adjustments to the labor market and industrial structure may induce short-term economic fluctuations and unemployment issues, negatively impacting the social economy. Addressing falling fertility rates requires government intervention. Strengthening the social security system is crucial to meet challenges posed by an aging population. Additionally, policies encouraging fertility are essential, involving support for healthcare, education, and childcare services. Human resource development must be emphasized to enhance workforce skills, adapting to labor market changes and economic needs. In conclusion, China's declining fertility rate profoundly influences social and economic development. Government measures are imperative to ensure sustainable and healthy socio-economic growth.

Fertility divergence across large and small areas

AbstractThis paper examines U.S. female fertility during 2005–2019. Small areas had higher fertility rates than large metropolitan statistical areas (MSAs) during each year. Both experienced fertility declines between 2005 and 2019. However, decreased fertility was more pronounced for large MSAs, and the fertility gap between large and small areas widened considerably. Investigation by age group reveals that diverging fertility across large and small areas is driven by women ages 25–34. We also use multivariate regression analysis for ages 25–34 to consider relationships between individual‐level and area‐level characteristics and spatial divergence in fertility. Employment patterns, foreign‐born status, and local housing costs are notable factors.

A population-based estimation of maternal mortality in Lagos State, Nigeria using the indirect sisterhood method

BackgroundPregnancy and delivery deaths represent a risk to women, particularly those living in low- and middle-income countries (LMICs). This population-based survey was conducted to provide estimates of the maternal mortality ratio (MMR) in Lagos Nigeria.MethodsA community-based, cross-sectional study was conducted in mapped Wards and Enumeration Areas (EA) of all Local Government Areas (LGAs) in Lagos, among 9,986 women of reproductive age (15–49 years) from April to August 2022 using a 2-stage cluster sampling technique. A semi-structured, pre-tested questionnaire adapted from nationally representative surveys was administered using REDCap by trained field assistants for data collection on socio-demographics, reproductive health, fertility, and maternal mortality. Data were analysed using SPSS and MMR was estimated using the indirect sisterhood method. Ethical approval was obtained from the Lagos State University Teaching Hospital Health Research and Ethics Committee.ResultsMost of the respondents (28.7%) were aged 25–29 years. Out of 546 deceased sisters reported, 120 (22%) died from maternal causes. Sisters of the deceased aged 20–24 reported almost half of the deaths (46.7%) as due to maternal causes, while those aged 45–49 reported the highest number of deceased sisters who died from other causes (90.2%). The total fertility rate (TFR) was calculated as 3.807, the Lifetime Risk (LTR) of maternal death was 0.0196 or 1-in-51, and the MMR was 430 per 100,000 [95% CI: 360–510].ConclusionOur findings show that the maternal mortality rate for Lagos remains unacceptable and has not changed significantly over time in actual terms. There is need to develop and intensify community-based intervention strategies, programs for private hospitals, monitor MMR trends, identify and contextually address barriers at all levels of maternal care.

What is driving the global decline of human fertility? Need for a multidisciplinary approach to the underlying mechanisms

An intense period of human population expansion over the past 250 years is about to cease. Total fertility rates are falling dramatically all over the world such that highly industrialized nations, including China and the tiger economies of SE Asia, will see their populations decline significantly in the coming decades. The socioeconomic, geopolitical and environmental ramifications of this change are considerable and invite a multidisciplinary consideration of the underlying mechanisms. In the short-term, socioeconomic factors, particularly urbanization and delayed childbearing are powerful drivers of reduced fertility. In parallel, lifestyle factors such as obesity and the presence of numerous reproductive toxicants in the environment, including air-borne pollutants, nanoplastics and electromagnetic radiation, are seriously compromising reproductive health. In the longer term, it is hypothesized that the reduction in family size that accompanies the demographic transition will decrease selection pressure on high fertility genes leading to a progressive loss of human fecundity. Paradoxically, the uptake of assisted reproductive technologies at scale, may also contribute to such fecundity loss by encouraging the retention of poor fertility genotypes within the population. Since the decline in fertility rate that accompanies the demographic transition appears to be ubiquitous, the public health implications for our species are potentially devastating.

On Some Demographic Structures and Economic Growth in Nigeria (2003–2022)

Effective development planning necessitates the integration of sound social and economic planning strategies. In Nigeria, demographic  and population data play a crucial role in shaping these plans. This research investigates the impact of demographic structure on the  country's economy, with a specific focus on key characteristics such as population size, birth rate, mortality rate, growth rate, GDP growth  rate, and fertility rate. The study analyzes demographic features alongside GDP growth rate data spanning from 2003 to 2022.  The findings reveal a robust correlation between birth rates and GDP growth, indicating that population dynamics significantly influence  economic development. Additionally, positive relationships are identified between death rates and GDP growth, underscoring the impact  of mortality issues on economic outcomes. The regression model demonstrates that demographic factors collectively mold Nigeria's  economic growth trajectory, shedding light on the intricate dynamics between demography and economic development. Through time  series analysis, the model exhibits low errors and high explanatory power. However, residual analysis highlights serial association,  emphasizing the temporal demographic effects on economic growth. Ultimately, the study underscores the potential contributions of  demographic characteristics to Nigeria's economy. Policymakers and economists keen on leveraging demographic shifts for economic  advancement will find valuable insights in this research. As demographic considerations increasingly play a pivotal role in Nigeria's  economic growth, strategic planning and decision-making must take these factors into account.

Validation and measurement properties of the Male and Female Fertility Knowledge Inventories (MFKI and FFKI) in Iranian couples

BackgroundOne of the most important population challenges during the last three decades has been the significant decrease in the fertility rate worldwide. Since the validity and reliability of the Male and Female Fertility Knowledge Inventories (MFKI and FFKI) have not been determined in Iran, we conducted this study to assess psychometric characteristics of the MFKI and FFKI in couples in Tabriz and Urmia, Iran.MethodsThis was a cross-sectional study, as the first part (quantitative phase) of a sequential explanatory mixed-method study. The current study was done on 1200 participants (600 women with their husbands) living in the northwestern region of Iran, between January 2023 and September 2023. The psychometric properties of the Persian version of the tool (MFKI and FFKI) were performed in 5 stages, including translation process, content validity, face validity, construct validity and reliability assesment.ResultsIn this study, the CVI, CVR, and impact scores of the MFKI tool were equal to 0.90, 0.88, 3.26 and CVI, CVR, and Impact scores of the FFKI tool were respectively equal to 0.95, 0.91 and 3.59, that it indicated a satisfactory level of content and face validity. Then, to check the construct validity, the results of the exploratory factor analysis of the MFKI tool on 13 items led to the identification of 3 factors, including Environment and reproductive health (ERH), Lifestyle factors (LSF) and Sperm quality (SQ), which explained 66% of the cumulative variance. The results of the exploratory factor analysis of the FFKI tool on 15 items led to the identification of 4 factors, including Reproductive health (RH), Lifestyle factors (LSF), Chance of conception (CHC) and Ovarian reserve and preservation (ORP), which explained 68% of the cumulative variance.ConclusionsThe findings of this study indicated that the Persian version of MFKI and FFKI has acceptable psychometric properties to measure the awareness of Iranian couples regarding fertility, which can be used as a screening tool for fertility knowledge by health care professionals and also as a reliable tool in research.

Do parenthood worries impede the birth of a second child? Differences according to the parent’s gender and spousal support in Finland

Objective: This study examines the extent to which the experience of parenthood worries among Finnish first-time parents predicts the probability of a second birth, and whether the associations differ according to the parent’s gender or the sufficiency of spousal support in parenting. Background: First-time parents’ withdrawal from having a second child has been connected to declining fertility rates in Finland and many other high-income countries; consequently, more understanding is needed about why parents potentially refrain from subsequent childbearing. Method: We utilize longitudinal survey data collected from Finnish parents (N = 544) in three waves (2016–2020). Results: The results show that experiencing parenthood worries significantly predicts the probability of a second birth. Specifically, the accumulation of parenthood worries predicted a lower probability of a second birth, and each additional worry decreased the probability significantly more for fathers compared to mothers. Although we found no gender differences regarding the associations between specific parenthood worries and the probability of a second birth, our results showed that fathers who worried about loneliness or having sole responsibility for parenting were less likely to have a second child than fathers with no such worries. In terms of the sufficiency of spousal support in parenting, we found, first, that among parents who received insufficient spousal support, those who worried about their parenting skills adequacy had a lower probability of a second birth than those with no such worries. Second, among parents with sufficient spousal support, worrying about their own ability to cope was associated with decreased probability of a second birth compared to those who did not experience such worry. Conclusion: Our findings provide new insights into the potential influence of parenthood worries experienced by first-time parents and the role of spousal support in subsequent childbearing.

Old-age support policy and fertility with strategic bequest motives

This paper presents an analysis of the effects of public old-age support on individuals’ fertility decisions and on the long-term equilibrium in an overlapping generation economy with strategic bequest motives. Parents must pay their adult children at least the reservation wage to receive informal old-age support from them (individual rationality constraint). Formal old-age support is financed through wage taxes on children. The increased present value of formal old-age support tends to increase old-age utility, thereby decreasing the family support demand and decreasing savings for the old age. The increased wage tax reduces the opportunity cost of child-rearing time, thereby increasing the fertility rate. The effects of increased formal old-age support on per-worker capital and labor are indeterminate, as is the effect on the long-term lifetime utility of individuals. A strategic bequest motive might engender a higher fertility rate than that of the social optimum.

Adapting to Demographic Shifts: China's Policy Approaches in Mitigating Healthcare and Retirement Challenges Posed by Aging Populations

China is witnessing a profound demographic transformation marked by a swift rise in its elderly population, posing significant challenges to healthcare and retirement systems. This study investigates the multifaceted impact of this demographic shift, evaluating the effectiveness of government policies in mitigating these challenges. Driven by increased life expectancy and declining fertility rates, this demographic transition necessitates strategic policy responses. The central argument revolves around scrutinizing the efficacy of China's policies in addressing healthcare and retirement hurdles arising from this demographic change. The hypothesis posits that governmental initiatives, such as healthcare infrastructure investments, pension system reforms, and expanded healthcare coverage, will partially alleviate existing challenges. Moreover, the paper hypothesizes on the societal impact of these policies, aiming to enhance elderly individuals' quality of life, alleviate healthcare-related financial burdens, and stimulate economic growth while relieving social welfare pressures. Employing a literature analysis methodology, this study critically evaluates existing scholarly works, policy documents, and empirical studies. While acknowledging the present challenges, it anticipates potential disparities in medical resources, sustainability concerns in pension systems, and issues surrounding the social integration of the elderly as the aging population expands. Recommendations underscore the necessity for adaptive policies to sustainably address these challenges. Through a comprehensive approach, this paper analyzes current policies, forecasts their impact, and conjectures future challenges, aiming to provide holistic insights into the effectiveness of policies aimed at managing the intricacies of an aging population in China.

Predictions of Malaysia Age-Specific Fertility Rates using the Lee-Carter and the Functional Data Approaches

Global fertility has been experiencing a significant decline, reaching towards the replacement ratio. This trend, coupled with increasing life expectancies, has led to the emergence of an ageing population. In this study, we delve into an analysis of fertility patterns among Malaysian women, considering both their childbearing age and ethnic groups. A comprehensive 63-year fertility dataset, from 1958 to 2020, were obtained from the Department of Statistics Malaysia.  These data were fitted into the Lee-Carter model and its modified version, which is the functional data model. The models were evaluated using the out-sample forecast error measures. Results indicate that the third-order functional data model able to capture most of variation present in the actual data, consequently outperforming the Lee-Carter model in forecasting fertility rates among Chinese and Indian populations. The 20-year forecasts reveal a noteworthy shift in maternal ages of the highest births to older ages suggesting a trend towards delayed pregnancies among women. It is predicted that the Malay total fertility rates will likely fall to below the replacement level reaching 1.71 in 2040 whereas Chinese and Indian total fertility rates will substantially decrease to the lowest level in history below 1.0 which are 0.54 and 0.70 respectively. The evolution in Malaysian fertility rates is an alarming fact as, together with low mortality rates, it may impact the Malaysian population structure in future. Proactive policy measures are urgently needed to address these demographic shifts.

Integration of immigrant women in Europe: a multifaceted approach

PurposeThis work analyzes female immigrants’ integration in the dimensions of education, labor market participation and fertility in 15 European countries, considering individual characteristics, including cultural background, host countries’ attitudes towards immigrants, the role of women in the family and country-specific integration policy. All these aspects taken together are crucial to understand the main patterns of integration focusing on gender differences.Design/methodology/approachWe focus on second- and first-generation male and female immigrants between the age of 25 and 41, with a length of stay of at least ten years. Enrollment ratios for tertiary education in parents’ countries, the total fertility rate and the female labor force in the mother’s country represent ethnic background. Diversity in the destination regions is captured by local attitudes towards immigrants, the perceived role of women and national policies to integrate migrants [Migrant Integration Policy Index (MIPEX)]. The data are drawn from the European Social Survey (ESS) for 2010–2018. Our results are based on ordinary least squares (OLS) and logit estimates; multilevel analysis was conducted.FindingsWe find significant evidence of gender role transmission from mother to daughter; age at immigration seems to be crucial to examine the importance of the culture of origin among immigrants. However, females are responsive to attitudes toward immigrants and gender equality in receiving societies, while integration policies, by defining the set of opportunities, may contribute to both genders’ tertiary education and women’s probability of being in the labor force.Social implicationsThis work underlines that integration policies favoring equal rights as nationals may contribute to both women’s tertiary education and their probability of being in the labor force.Originality/valueWe explore female integration in Europe in the dimensions of education, labor market, fertility and the role of both immigrants’ cultural heritage and specific aspects of destination countries. Previous research, particularly in the USA, has generally focused on some of these features at the expense of a more comprehensive approach. This study builds upon the existing literature and contributes to it by taking a multifaceted approach to female integration in Western Europe, which presents not only an institutional context different from the USA but also some heterogeneity with respect to integration policies and socioeconomic factors.
