Prediction of childbearing tendency in women on the verge of marriage using machine learning techniques.

The declining fertility rate and increasing marriage age among girls pose challenges for policymakers, leading to issues such as population decline, higher social and economic costs, and reduced labor productivity. Using machine learning (ML) techniques to predict the desire to have children can offer a promising solution to address these challenges. Therefore, this study aimed to predict the childbearing tendency in women on the verge of marriage using ML techniques. Data from 252 participants (203 expressing a "desire to have children" and 49 indicating "reluctance to have children") in Abadan, and Khorramshahr cities (Khuzestan Province, Iran) was analyzed. Seven ML algorithms, including multilayer perceptron (MLP), support vector machine (SVM), logistic regression (LR), random forest (RF), J48 decision tree, Naive Bayes (NB), and K-nearest neighbors (KNN), were employed. The performance of these algorithms was assessed using metrics derived from the confusion matrix. The RF algorithm showed superior performance, with the highest sensitivity (99.5%), specificity (95.6%), and receiver operating characteristic curve (90.1%) values. Meanwhile, MLP emerged as the top-performing algorithm, showcasing the best overall performance in accuracy (77.75%) and precision (81.8%) compared to other algorithms. Factors such as age of marriage, place of residence, and strength of the family center with the birth of a child were the most effective predictors of a woman's desire to have children. Conversely, the number of daughters, the wife's ethnicity, and the spouse's ownership of assets such as cars and houses were among the least important factors in predicting this desire. ML algorithms exhibit excellent predictive capabilities for childbearing tendencies in women on the verge of marriage, highlighting their remarkable effectiveness. This capacity to offer accurate prognoses holds significant promise for advancing research in this field.

Effectiveness of multimedia education on the childbearing intention in one-child women: a field trial study.

BACKGROUND: childbearing is a key component of population movements and sustainable development in low-fertility nations. This study was conducted with the aim of determining the impact of multimedia education on the childbearing intention in One-child women of Maragheh city. METHOD: In this intervention study in Maragheh in 2023, 94 women with one child were randomly selected and placed in two intervention and control groups. Before the intervention, people were examined using demographic information and Miller's questionnaire of desire to have children. Then, For the intervention group, three 60-minute multimedia training videos were shown in person for three weeks, and the control group did not receive any training. The data were collected using the researcher's demographic questionnaire and Miller's childbearing questionnaire in three stages before the intervention, immediately after and six weeks after the intervention. Data analysis was done with SPSS version 16 software. RESULTS: There was no significant difference between the two groups in terms of the average score of desire to have children and demographic variables (p > 0.05). Before the intervention, there was no significant difference between the intervention and control groups in terms of the demographic characteristics of the subjects and the average score of women's willingness to have children in the positive and negative dimensions. While after the multimedia educational intervention, the average score of desire to have children in positive and negative dimensions, immediately after the intervention and six weeks after the intervention, had a significant difference compared to before the intervention (p < 0.001). CONCLUSION: The findings of the study showed that carrying out multimedia educational interventions to single-child women can have a positive effect on their desire to have children. It seems that the implementation of such programs is effective in the conscious decision of families to have children and ultimately increases the intention of the individual to carry out the behavior.

Causal association between family health, perceived relationship quality components, and attitudes toward childbearing in Iranian women: A WHO model analysis.

BACKGROUND: Given the unprecedented global decline in fertility as a major demographic development in recent years, the present study was conducted to determine Causal association Between Family Health, Perceived Relationship Quality Components, and Attitudes toward Childbearing in Iranian Women: A WHO Model Analysis METHODS: In 2023, this descriptive study recruited 400 married women presenting to selected comprehensive health centers affiliated to Alborz University of Medical Sciences, Karaj, Iran. The data were collected through multistage stratified cluster sampling and using a socioeconomic status questionnaire (Ghodratnama), the Perceived Relationship Quality Components (PRQC) scale, the family-of-origin scale (FOS), the attitudes toward fertility and childbearing scale (AFCS) and a demographic checklist were analyzed in SPSS 25 and LISREL 8.8. RESULTS: According to the path analysis, family health exerted the most significant and positive causal effect on attitudes to childbearing directly through one path (B = 0.334) and relationship quality (B = 0.698) and duration of married life (B = 0.387) both directly and indirectly. The number of children (B = -0.057), however, exerted the most significant and negative causal effect on attitudes to childbearing through both paths. CONCLUSIONS: The present findings suggested the significant effects of family health and relationship quality on attitudes toward childbearing. It is therefore recommended that these variables be screened in comprehensive health centers, the associated limitations and problems be identified and appropriate training and counseling solutions be provided by health specialists.

Reproductive function and behaviors: an update on the role of neural estrogen receptors alpha and beta.

Infertility is becoming a major public health problem, with increasing frequency due to medical, environmental and societal causes. The increasingly late age of childbearing, growing exposure to endocrine disruptors and other reprotoxic products, and increasing number of medical reproductive dysfunctions (endometriosis, polycystic ovary syndrome, etc.) are among the most common causes. Fertility relies on fine-tuned control of both neuroendocrine function and reproductive behaviors, those are critically regulated by sex steroid hormones. Testosterone and estradiol exert organizational and activational effects throughout life to establish and activate the neural circuits underlying reproductive function. This regulation is mediated through estrogen receptors (ERs) and androgen receptor (AR). Estradiol acts mainly via nuclear estrogen receptors ERα and ERß. The aim of this review is to summarize the genetic studies that have been undertaken to comprehend the specific contribution of ERα and ERß in the neural circuits underlying the regulation of the hypothalamic-pituitary-gonadal axis and the expression of reproductive behaviors, including sexual and parental behavior. Particular emphasis will be placed on the neural role of these receptors and the underlying sex differences.

Reproductive plan of women in Czechia in the context of late reproductive regime and the COVID-19 pandemic.

The article focuses on short-term (up to three years) and long-term (three years and beyond) reproductive intentions of women aged 18-49 living in the Czechia. Reproductive plans are predominantly formulated at the threshold of adulthood and only 11 % of women under 25 are unsure of their reproductive plans. In the short term, childbearing is planned with the greatest intensity at the ages of 25-29 and 30-34 (when 47 and 33 % of women plan to have a child, respectively), while for childless women the intensity of planning peaks slightly later, at the ages of 30-34 and 35-39 (planning rates of 54 and 50 %, respectively). Older women are not giving up their desire to pursue their reproductive plans. Despite the health risks associated with motherhood at an older age, 20 % of childless women aged 40-44 plan to have their first child in the next three years or later. In addition to age and the current number of children, short- and long-term reproductive plans also differ by women's education, with college graduates more likely to plan to have (another) child in the short and long term than women with less education. At the same time, short-term plans are influenced by women's partnership status, and in the case of long-term reproductive plans, the influence of perceptions of the long-term impact of the COVID-19 pandemic was observed.

Factors associated with the health and reproductive autonomy of Quilombola women in Brazil.

Objective: To verify the association between reproductive autonomy and sociodemographic, sexual, and reproductive characteristics in Quilombola women (a term indicating the origin of politically organized concentrations of Afro-descendants who emancipated themselves from slavery). Methods: Cross-sectional and analytical study with 160 women from Quilombola communities in the southwest of Bahia, Brazil. Data were collected using the Reproductive Autonomy Scale and the questionnaire from the National Health Survey (adapted). Results: Out of the 160 participating women, 91.9% declared themselves as black, one out of every three were aged ≤ 23 years, 53.8% were married or had a partner, 38.8% had studied for ≤ 4 years, over half (58.1%) were unemployed, only 32.4% had a monthly income > R$ 430 (80 US dollars), 52.5% had their first menstruation at the age of 12, 70.7% had not accessed family planning services in the last 12 months, and over half used some method to avoid pregnancy (59.0%). The women had a high level of reproductive autonomy, especially in the "Decision-making" and "Freedom from coercion" subscales with a score of 2.53 and 3.40, respectively. A significant association (p<0.05) was found between the "Total reproductive autonomy" score and marital status, indicating that single or unpartnered women had higher autonomy compared to married or partnered women. Conclusion: The association of social determinants of health such as marital status, education, and age impacts women's reproductive choices, implying risks for sexual and reproductive health. The intergenerational reproductive autonomy of Quilombola women is associated with sociodemographic and reproductive factors.

Uncertainty and flexibility of fertility intentions.

Large-scale survey data is widely used to study the intention to have a(nother) child. However, there are further opportunities to understand how these intentions are revised over the life course and the uncertainty surrounding them. We aim to further outline the importance of simultaneously considering change and uncertainty in fertility decision-making. Specifically, we identify uncertainty in the "probably not" and "probably yes" responses to questions on whether an individual intends to have a(nother) child, and compare the differences in individuals' stated intention between survey waves. Using panel data from the Generations and Gender Survey (GGS) for Austria, France, Hungary, Italy, and Poland, we study short-term followed by long-term (overall) fertility intentions. First, descriptive analyses compare and visualise the prevalence of uncertainty intentions at first and second wave using Sankey diagrams. Next, multivariate analyses on transitions in intentions focus on partnership and employment context. The results reveal that for both short-term and overall intentions, four in ten respondents are uncertain about intending a (further) child. Further, one in two report a different intention between waves, with changes mainly occurring from one "probably" response to another (e.g., "probably not" to "probably yes") or through a shift in increasing or lessening certainty (e.g., "probably yes" to "definitely yes"). The childless exhibit by far the greatest uncertainty and revision. Multivariate analyses show that partnership and employment are associated with gradual transitions and larger changes in intentions. Our results also show that fertility intentions form to a large extent along a spectrum of certainty-from "definitely not," to "probably not," to "probably yes," to "definitely yes," and finally to the birth of a child.

Diverse pathways to permanent childlessness in Singapore: A latent class analysis.

The proportions of adults reaching midlife without having children have been rising rapidly across the globe, particularly in Asia. However, little is known about the pathways to permanent childlessness within the region's childless population. This study utilized latent class analysis (LCA) to typologize pathways to childlessness based on dynamic characteristics of multiple life domains (i.e., partnership, education, and occupation) among 489 childless Singaporeans aged 50 and above from a 2022 nationwide survey. Additionally, we utilized multinomial logistic regressions to examine the sociodemographic correlates of pathway profiles and Shannon's entropy index to assess the heterogeneity in pathways to childlessness among successive cohorts. Results revealed five distinct profiles of pathways to childlessness: the Never-Married Semi-Professionals, the Low-Flex Blue-Collars, the Highly Educated Professionals, the Ever-Married Semi-Professionals, and the Flexible Blue-Collars. These pathway profiles were significantly associated with sociodemographic characteristics such as gender and family background. Women's pathways to childlessness were more standardized and heavily influenced by partnership characteristics, compared to those of men. The childless from privileged family background were less likely to follow pathways characterized by disadvantageous education and occupational status. There were also rising trends of voluntary childlessness among married childless individuals and increasing heterogeneity in pathways to childlessness across successive birth cohorts. In sum, our findings are consistent with some of the predictions of the Second Demographic Transition theory, suggesting that Singapore may be experiencing a demographic transition characterized by rising childlessness, decoupling of marriage and childbearing, and de-standardization of the life course.

Sexual risk behavior and knowledge about sexually transmitted infections in a university population in Sorocaba, Brazil / Comportamento sexual de risco e conhecimento sobre infecções sexualmente transmissíveis em uma população universitária na cidade de Sorocaba/SP

INTRODUCTION: Sexually transmitted infections (STIs) are a major public health problem to which young people are highly exposed and knowledge about vulnerabilities that affect them is needed. OBJECTIVE: To evaluate the knowledge about STIs and sexual behavior of a university population in the city of Sorocaba/SP. METHODS: A descriptive, cross-sectional study was conducted with data collection realized by an online application with qualitative and quantitative characteristics. RESULTS: Four hundred and seventy-seven (477) university students from different areas of knowledge were analyzed. The majority pointed to the beginning of sexual life between 15 and 18 years old. Information about sex education was obtained mainly through parents and/ or guardians, while little additional knowledge was obtained after entering higher education. Biological and Health Sciences students achieved a higher score on the knowledge questionnaire and were less likely (0.391) to contract STIs when compared to Applied Social Sciences or Engineering students (2.8 and 2.9 more likely, respectively). CONCLUSION: Students who demonstrated greater knowledge about STIs and acquired more information on the subject during graduation were less likely to become infected, suggesting that campaigns aimed at the university public are essential for the prevention and control of these pathogens.

INTRODUÇÃO: As infecções sexualmente transmissíveis (IST) são um grande problema de saúde pública, ao qual os jovens apresentam alta exposição, sendo necessário um maior conhecimento sobre as vulnerabilidades que os acometem. OBJETIVO: Avaliar o conhecimento sobre as IST e o comportamento sexual de uma população universitária na cidade de Sorocaba/SP. MÉTODOS: Realizou-se um estudo descritivo, de corte transversal, com a coleta de dados realizada por meio de aplicação online de questionário com características qualitativas e quantitativas. RESULTADOS: Quatrocentos e setenta e sete (477) universitários de diferentes áreas de conhecimento foram avaliados. A maioria dos relatos apontou para o início da vida sexual entre 15 e 18 anos. As informações sobre educação sexual foram obtidas principalmente por intermédio dos pais e/ou responsáveis, enquanto pouco conhecimento adicional foi obtido após o ingresso no Ensino Superior. Estudantes de Ciências Biológicas e da Saúde alcançaram o maior score no questionário sobre conhecimento e apresentaram chances menores (0,391) de contrair IST, quando comparados aos estudantes de Ciências Sociais Aplicadas ou Engenharias (2,8 e 2,9 mais chances, respectivamente). CONCLUSÃO: Os estudantes que demonstraram maior conhecimento sobre as IST e que adquiriram mais informações sobre o tema durante a graduação apresentaram chances menores de se infectar, o que sugere que campanhas destinadas ao público universitário são essenciais para a prevenção e o controle desses patógenos.

Reproductive behaviour and fertilized spawns in cultured Solea senegalensis broodstock co-housed with wild breeders during their juvenile stages.

The reproductive failure of Senegalese sole (Solea senegalensis) cultured males (reared entirely in captivity from egg through to adult) that do not participate in reproductive behaviours to fertilise spawns, results in a problem to achieve reproductive control in captivity. However, cohabitation with wild males has led to an increase in the involvement of cultured males in reproductive behaviour, although their contribution to fertilised spawning is still lower than that of wild breeders. This study aimed to examine the effect of different social conditions, on the reproductive behaviour and spawning success of cultured breeders over three reproductive seasons. Before starting this study, different social learning opportunities were provided to the breeders from the juvenile to the pubertal stages of the individuals. Behaviour and spawning were evaluated in four experimental groups of cultured breeders: two groups (W1 and W2) that prior to this study were reared during the juvenile stage with wild breeders that fertilized spawns, a Culture breeder group (CB) that was previously reared with cultured breeders that spawned unfertile eggs, and a negative control group (CN) that was reared in isolation from adult fish. During the three reproductive seasons, spawning was obtained from all groups. Generally, the first year had the highest egg production and the third year the lowest. However, fertilised eggs were only obtained from W1 in the first year. A total of eight fertilised spawns were collected with a fertilisation rate of 28.02 ± 13.80 % and a hatching rate of 15.04 ± 10.40 %. The mean number of larvae obtained per spawn was 7,683 ± 5,947 and the total number of larvae from all eight spawns was 61,468. The paternity analysis assigned 64.3 % of larvae to a single couple of breeders, while 34.3 % of larvae were not assigned to any single family, but inconclusively to more than three parents. The highest locomotor activity was observed in W1, while no significant differences were observed in the number of movements within W2, CB and CN. In all groups, during the peak of locomotor activity (19h00-20h00), the main reproductive behaviours observed were Rest the Head and Follow, while the Guardian behaviour was low and Coupled behaviour was only observed in W1. Over time, the reproductive behaviours decreased, except for Follow. The social learning opportunities provided by cohabitation with wild fish during juvenile stages prior to spawning in W1, increased activity and fertilised spawning. However, the number of successful spawns was low and over time stopped in association with a decrease in reproductive behaviour. This suggests that other mechanisms of behavioural learning could be involved in reproductive success, such as reproductive dominance, environmental conditions or hormonal interactions that could affect physiological processes in the reproduction of captive breeders.

Women's involvement in decision-making and association with reproductive health behaviors: findings from a cross-sectional survey in Niger.

BACKGROUND: Though women in Niger are largely responsible for the familial health and caretaking, prior research shows limited female autonomy in healthcare decisions. This study extends current understanding of women's participation in decision-making and its influence on reproductive health behaviors. METHODS: Cross-sectional survey with married women (15-49 years, N = 2,672) in Maradi and Zinder Niger assessed women's participation in household decision-making in health and non-health issues. Analyses examined [1] if participation in household decision-making was associated with modern contraceptive use, antenatal care (ANC) attendance, and skilled birth attendance at last delivery and [2] what individual, interpersonal, and community-level factors were associated with women's participation in decision-making. RESULTS: Only 16% of the respondents were involved-either autonomously or jointly with their spouse-in all three types of household decisions: (1) large purchase, (2) visiting family/parents, and (3) decisions about own healthcare. Involvement in decision making was significantly associated with increased odds of current modern contraceptive use [aOR:1.36 (95% CI: 1.06-1.75)] and four or more ANC visits during their recent pregnancy [aOR:1.34 (95% CI: 1.00-1.79)], when adjusting for socio-demographic characteristics. There was no significant association between involvement in decision-making and skilled birth attendance at recent delivery. Odds of involvement in decision-making was significantly associated with increasing age and household wealth status, listening to radio, and involvement in decision-making about their own marriage. CONCLUSION: Women's engagement in decision-making positively influences their reproductive health. Social and behavior change strategies to shift social norms and increase opportunities for women's involvement in household decision making are needed. For example, radio programs can be used to inform specific target groups on how women's decision-making can positively influence reproductive health while also providing specific actions to achieve change. Opportunities exist to enhance women's voice either before women enter marital partnerships or after (for instance, using health and social programming).

A crisis in the life course? Pregnancy loss impacts fertility desires and intentions.

BACKGROUND: An unintended spontaneous termination of a pregnancy can be a traumatic experience affecting the subsequent life course, but has received little attention in socio-demographic studies on fertility intentions or behavior. The theoretical background of our study draws on considerations from life course research, the Theory of Planned Behavior and the Traits-Desires-Intentions-Behavior framework. OBJECTIVE: This study investigates whether the experience of pregnancy loss changes the fertility desires and intentions of women in their subsequent life course. METHODS: We use 11 waves of the Panel Analysis of Intimate Relationships and Family Dynamics (pairfam) with 5197 women in total, of which 281 women (5.4%) reported a miscarriage. Data have been collected annually in Germany since 2008. We investigate four dependent variables capturing different indicators of the ideational dimension of fertility: Personal ideal number of children, realistic number of (additional) children, intention to have a(nother) child in the next two years and importance of having a(nother) child. We study the intrapersonal changes in these items among women after a pregnancy loss, applying linear fixed effect regression models. Controls include parity, age, partnership status, pregnancy status and the interaction of pregnancy loss with whether the woman already had children before the pregnancy loss. RESULTS: We found that the importance of having a(nother) child and the intention to have a(nother) child in the next two years increase after a pregnancy loss. These patterns can only partially be explained by control variables. By contrast, an effect on the ideal number of children as well as the realistic number of children could not be found. The patterns varied, however, across age and stage in the life course, most importantly between mothers and childless women. CONCLUSIONS: Our results demonstrate that the effect of pregnancy loss on the subsequent life course varies across the indicators used and by duration after the pregnancy loss. Overall, they suggest that specifically the younger women in our sample might perceive pregnancy loss as a temporary crisis in their transition to motherhood, or to having another child, and as an impetus to reinforce their fertility goals, while for older respondents this might mark the end of their fertility career. Against the backdrop of rising ages at childbirth, future research on fertility and reproductive health care should pay more attention to reproductive complications and how affected women can be supported in coping with them.

'Do I want children later in life?' Reproductive intentions of 1700 adolescents.

PURPOSE: In the past decades, a positive attitude towards having children has been reported in young people. The current generation of adolescents is increasingly concerned about environmental cataclysm which may have an impact on their desire for children. The purpose of this study is to depict the current attitudes in Flemish adolescents towards having children. MATERIALS AND METHODS: All secondary schools in Flanders (Belgium) were invited to distribute an anonymous online survey among their pupils in the last two years of secondary education. In total, 1700 adolescents participated and provided quantitative and qualitative data on their reproductive intentions. RESULTS: Most pupils expressed a desire for children (60.2%), 24.7% were undecided and 10.8% were not willing to have children. Significantly more boys than girls would like to have children (67.0% versus 61.7%, p < 0.01). Adolescents who were uncertain about having children or not interested, reported financial reasons and loss of freedom as most important reasons. CONCLUSIONS: While most adolescents would like to have children in the future, one in four adolescents is undecided and one in ten indicates a wish to remain childless; reasons for wanting children are rather personal, reasons for not wanting children are rather pragmatic.

A desire for parenthood is no longer the norm: 60% of Flemish adolescents would like to build a family, but many are considering a future without children.

"My Mother Persuaded Me to Have More Children", Understanding the Influence of Social Network on Fertility Behavior in Sub-Saharan Africa.

Introduction: Despite the adoption of an antenatal demographic transition model in sub-Saharan Africa, population growth continues to soar in the region. The reasons for population growth are nebulous and should be approached from different perspectives. Inadequate attention has been paid to how social pressures shape reproductive behavior. Thus, this study examines the association between social networks and fertility behavior in sub-Saharan Africa. Methods: This study used a cross-sectional design that employed a qualitative method to conduct 28 in-depth interviews among married women. Data was collected in 2023. Thematic analyses were utilized to interpret the results. Results: Parental pressure, the desire for more children, the desire for male children, values placed on children, norms, and pronatalist culture were associated with high fertility in sub-Saharan Africa. Conclusions: Thus, there is a need for more awareness of family planning and contraceptive use in order to reduce fertility in sub-Saharan Africa.

Women's reproductive choice and (elective) egg freezing: is an extension of the storage limit missing a bigger issue?

Egg freezing can allow women to preserve their eggs to avoid age-related infertility. The UK's recent extension of elective egg freezing storage has been welcomed as a way of enhancing the reproductive choices of young women who wish to delay having children. In this paper, I explore the issue of enhancing women's reproductive choices, questioning whether there is a more significant aspect overlooked in egg freezing. While increasing storage limits expands reproductive choices for some women, focus on this extension alone, I argue, misses a fundamental issue with egg preservation that often remains ignored; the importance of effective information on egg freezing and the effect this has on women's reproductive choices. Ultimately, I highlight the crucial role of balanced information in enhancing women's choices regarding egg freezing and argue that focusing on extending and increasing provision may obscure this real opportunity to empower women and their authentic reproductive choices.

What factors influence couples' decisions to have children? Evidence from a systematic scoping review.

BACKGROUND: One of the most significant demographic challenges over the past three decades has been the substantial reduction in fertility rates, worldwidely. As a developing country, Iran has also experienced a rapid decline in fertility over the past decades. Understanding factors influencing fertility is essential for development programs. Moreover, it's crucial to study the parameters that affect the intention for childbearing in any society. Therefore, through a systematic scoping review, the present study investigates the factors influencing couples' decisions toward childbearing. METHODS: This study was a systematic scoping review conducted in 2023. To design and conduct this scoping review, Joanna Briggs Institute's Protocol (Institute TJB, The Joanna Briggs Institute Reviewers ' manual 2015; methodology for JBI scoping reviews, 2015) was used and the framework presented by Levac et al. (2010) was also used as a guide for conducting this review. Studies were searched in three main databases including ISI Web of Sciences, PubMed, and Scopus, using a predefined search strategy. Google Scholar was also used for complementary search. The search period was from 2002 to 2022. RESULTS: A total of 18,454 studies were identified across three primary databases. After evaluating articles in three distinct phases based on title, abstract, and full-text, 46 articles were deemed eligible for inclusion in the scoping review. The qualitative analysis of the collected data from the selected studies through the scoping review led to classifying factors influencing households' desire for childbearing into eight main themes and 101 sub-themes. The main themes associated with factors impacting households' intention for childbearing encompass individual determinants, demographic and familial influencing factors, cultural elements, social factors, health-related aspects, economic considerations, insurance-related variables, and government support/incentive policies. CONCLUSIONS: Comprehensive and holistic attention from governments and officials toward the various factors affecting households' intention and behavior regarding childbearing appears beneficial and effective. Furthermore, given the relative ineffectiveness of some of the current government's supportive/incentive policies to increase couples' desire for childbearing, it seems necessary to review and amend these policies. This review should address the most significant challenges and factors contributing to couples' reluctance to childbearing or strengthen factors that can play a substantial role in fostering fertility and childbearing desires.

[The social hygienic aspects of reproductive behavior of women aged 40-45 years].

In the context of forecasted decreasing of natality, actuality of studying its causes for organizational decision-making increases. The purpose of the study was to determine factors affecting reproductive behavior of women aged 40-45 years residing in areas with different natality levels in 2020-2021. The cohort, analytical, sociological methods were applied. The results of study demonstrated that in areas with high natality level most of urban women with higher education and high income resides in conditions of dormitory or mortgage flat and working in profile of their specialty. They are characterized by belated marriage that results in postponed child-bearing. The areas with low natality are characterized by dwelling of rural women with secondary or secondary specialized education. They reside in their own homes and work in other occupations than their specialty. The analysis of social status of women of different age groups will permit more selective approach in developing measures of increasing natality in modern conditions.

[The choice of a life without children under the influence of societal concerns]. / Le choix d'une vie sans enfant sous l'influence des préoccupations sociétales.

THE CHOICE OF A LIFE WITHOUT CHILDREN UNDER THE INFLUENCE OF SOCIETAL CONCERNS. Previously unpublished data from 2021 provide an update on the motivations of people who choose not to have children, considering a context of strong social pressure to conceive and a declining birth rate in France. Moreover, childlessness is still a minority phenomenon, and still subject to a certain amount of stigmatization It is part of a social context with a growing concern for ecological issues and the difficulties to achieve gender equality. Taking all of this into consideration, people who choose not to have children are in many ways well anchored in current issues.

LE CHOIX D'UNE VIE SANS ENFANT SOUS L'INFLUENCE DES PRÉOCCUPATIONS SOCIÉTALES. Des données inédites datant de 2021 permettent de faire le point sur les motivations des personnes volontairement sans enfant dans un contexte de forte pression sociale à concevoir et de baisse de la natalité en France. En outre, le non-désir d'enfant est toujours un phénomène minoritaire et encore sujet à une certaine forme de stigmatisation. Par ailleurs, il s'inscrit dans un contexte social où la question écologique prend de l'ampleur et où l'égalité femmes-hommes peine toujours à se réaliser. Les personnes volontairement sans enfant sont, en ce sens, bien ancrées dans la société actuelle.

Reproductive Decision Making of Spanish Women Living With HIV: A Constructivist Grounded Theory Study.

ABSTRACT: The process of reproductive decision making among women living with HIV is intricate and multifaceted, influenced by health considerations, societal factors, and personal values. In this study, we employed Charmaz's Constructivist Grounded Theory to understand how Spanish women living with HIV make decisions regarding reproduction. We conducted 26 face-to-face interviews until data saturation was achieved. Findings suggested that social constructs such as femininity and motherhood play a significant role in the reproductive decision-making process for women living with HIV. The women's beliefs about HIV, doubts, marginalizing situations, and health barriers create challenges to making reproductive decisions. These findings provide valuable implications for designing care plans that meet the unique sexual and reproductive health needs of women with HIV. An integrated and comprehensive multidisciplinary counseling approach is necessary to improve the quality of care.

Development and psychometric evaluation of the questionnaire on the contributing factors of tendency towards voluntary single-childedness and childlessness: a mixed method study.

Couples' tendency towards voluntary single-childedness and childlessness (VSCC) has turned into a major challenge in all societies and led to different problems such as population aging. A key step to VSCC management is to determine its contributing factors through valid and reliable instruments. This exploratory sequential mixed method study (qualitative-quantitative) was conducted in 2020-2021. Phases of qualitative consists of all couples aged 15-49 in Babol, Iran, who were single or childless. Sampling is based on the purpose, and the number of samples is 20 couples. To collect data, face-to-face and semi-structured interviews were conducted with the participants. Sampling continued until data saturation. The data were analyzed by the conventional content analysis method and quantitative phase. Initially, a qualitative study was conducted on twenty couples, and were analyzed through conventional content analysis. Findings were used to develop QFT-VSCC and then, the face, content, and construct validity as well as reliability were assessed. Construct validity was assessed through exploratory and confirmatory factor analyses and reliability was assessed through internal consistency and stability assessments. The results of the qualitative part analysis consist of 140 codes, 30 primary categories, and nine main categories and two themes (individual limitations and social limitations). The primary QFT-VSCC had 78 items. Fifty-eight items were omitted during validity assessment and the remaining twenty-two items were loaded on five factors during factor analysis. These factors were threatened priorities, inappropriate familial context for childbearing, sense of occupational and social insecurity for the child, social modeling of childlessness, and tendency towards change or stability in marital life. The five factors explained 52.56% of the total variance. All model fit indices in confirmatory factor analysis were acceptable and the Cronbach's alpha values of QFT-VSCC and all its factors were more than 0.70. The results of convergent validity analysis revealed that all factors had an AVE value greater than 0.5, and the HTMT index for all factors was less than 0.85. This indicated that discriminant validity had been achieved. QFT-VSCC is a simple valid and reliable instrument for VSCC assessment among both men and women.
