Sex composition of children, parental separation, and parity progression

Previous studies that have studied parental gender preferences for children have analysed either divorce or parity progression. We use Finnish register data that make it possible to study both events simultaneously by following the same couples with childr

Son preference exerts a strong influence over contraceptive and fertility decisions in many South Asian countries. In Pakistan, where fertility remains high and contraceptive use low, research on son preference has been limited. Data from Pakistan Demographic and Health Surveys conducted in 1990-1991, 2006-2007 and 2012-2013 were used to examine potential indicators and outcomes of son preference. Descriptive analyses looked at sex composition preferences of men and women, as well as the sex ratio at last birth. Multivariate logistic regression analyses examined parity progression by birth order, while multinomial logistic regression was used to identify associations between sex composition and use of permanent, temporary and traditional contraceptive methods. Parity progression and choice of contraceptive method are increasingly associated with the sex composition of children. Many respondents wanted at least two sons, though most also wanted at least one daughter. Analyses suggest that the prevalence of modern contraceptive use among parous women would have been 19% higher in 2012-2013 in the absence of son preference. Permanent method use was extremely low among women with no sons and increased significantly with number of sons. The association between number of sons and use of temporary methods was weaker, while son preference had little relationship with traditional method use. The association of son preference with parity progression and modern contraceptive use has become stronger in Pakistan. Continuation of the fertility transition may be difficult unless the degrees of differential stopping behavior and differential contraceptive use decline.

The desire for sons often influences fertility behavior in India. Women with a small number or low proportion of sons may be more likely than other women to continue childbearing. Data from India's 2005-2006 National Family Health Survey were used to examine several hypotheses regarding the association between sex composition of children and parity progression among parous women aged 35-49. Descriptive analyses and multivariate logistic regression analysis that controlled for possible confounders were performed separately by parity. Women with more sons than daughters were generally less likely than those with more daughters than sons to continue childbearing; parity progression driven by the desire for sons accounted for 7% of births. At any given parity, the last-born child of women who had stopped childbearing was more likely to be a son than a daughter (sex ratios, 133-157). In multivariate analyses, women without any sons were more likely than women without any daughters to continue childbearing at parities 1-4 (odds ratios, 1.4-4.5). At most or all parities, continued childbearing was positively associated with having had a child who died, and negatively associated with levels of women's education and media exposure and with household wealth. The desire for sons appears to be a significant motivation for parity progression. Although population policies that reduce family size are essential, also imperative are policies that reduce desire for sons by challenging the perception that sons are more valuable than daughters.

The presence, number, sex, and age composition of children within families can have important influences on couples’ marital outcomes. Children are valued across settings, but their value in settings where there is an absence of formalized social security is distinctive. This paper explores the influences of childlessness, and different number, age, and sex compositions of children, on the odds of marital dissolution among couples in rural Nepal. Results reveal that childless couples face significantly higher odds of dissolution than couples with at least one child, and each additional child—up to three children—reduces couples’ odds of dissolution. Furthermore, having a child aged under two reduces couples’ odds of marital dissolution, but interactions reveal that this age effect only holds at parity one. Surprisingly, despite a history of son preference in this setting, there is no evidence that children’s within-parity sex composition is associated with the odds of marital dissolution.

This thesis aims to investigate whether the variation in sex composition of children can explain the variation of Vietnamese women's fertility desire. Vietnam has experienced rapid fertility decline since the middle of the 20th century but within a broader context of strong cultural norms regarding son preference. Thus, the sex composition of children is one of the key determinants of reproductive behavior within Vietnam. To my knowledge, no previous study has examined the relationship between sex composition of children and women's fertility desires in Vietnam. Using data from the 2014 Vietnam Multiple Indicator Cluster Survey (MICS) I investigate the association between sex composition of children and desire for additional children among women in reproductive age (15 to 49) across Vietnam (N=5,605). Multivariate logistic regression models show a statistically significant positive association between the sex composition of children and women's fertility desire, after controlling for social norms of fertility preference, demographic and socioeconomic factors. For each group of women (those with one child, those with two children, and those with three or more children) women with no son are more likely to have higher fertility desire compared to women with at least one son. However, women with both son (s) and daughter (s) tend to have lower fertility desire compared to those who have all sons. My results suggest that Vietnam's traditional cultural norm of son preference has a strong influence on fertility desire, and potentially reproductive behavior. These findings have implications for family planning policies in Vietnam.

BackgroundThe sex composition of existing children has been shown to influence childbearing decision-making and behaviors of women and couples. One aspect of this influence is the preference for sons. In India, where son preference is deeply entrenched, research has normally focused on rural areas using cross-sectional data. However, urban areas in India are rapidly changing, with profound implications for childbearing patterns. Yet, evidence on the effect of the sex composition of current children on subsequent childbearing intentions and behavior in urban areas is scant. In this study, we analyze the impact of sex composition of children on subsequent (1) parity progression, (2) contraceptive use, and (3) desire for another child.MethodsWe analyze prospective data from women over a four year period in urban Uttar Pradesh using discrete-time event history logistic regression models to analyze parity progression from the first to second parity, second to third parity, and third to fourth parity. We also use logistic regression models to analyze contraceptive use and desire for another child.ResultsRelative to women with no daughters, women with no sons had significantly higher odds of progressing to the next birth (parity 1 – aOR: 1.31; CI: 1.04–1.66; parity 2 – aOR: 4.65; CI: 3.11–6.93; parity 3 – aOR:3.45; CI: 1.83–6.52), as well as reduced odds of using contraception (parity 2 – aOR:.58; CI: .44–.76; parity 3 – aOR: .58; CI: .35–.98). Relative to women with two or more sons, women with two or more daughters had significantly higher odds of wanting to have another child (parity 1 – aOR: 1.33; CI: 1.06–1.67; parity 2 – aOR: 3.96; CI: 2.45–6.41; parity 3–4.89; CI: 2.22–10.77).ConclusionsOur study demonstrates the pervasiveness of son preference in urban areas of Uttar Pradesh. We discuss these findings for future programmatic strategies to mitigate son preference in urban settings.

To explore whether there exist differences in cognitive development between singletons and twins born after in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). A total of 566 children were recruited for the study, including 388 children (singletons, n=175; twins, n=213) born after IVF and 178 children (singletons, n=87; twins, n=91) born after ICSI. The cognitive development was assessed using the Chinese-Wechsler Intelligence Scale for Children (C-WISC). For all pre-term offspring, all the intelligence quotient (IQ) items between singletons and twins showed no significant differences no matter if they were born after IVF or ICSI. There was a significant difference in the cognitive development of IVF-conceived full-term singletons and twins. The twins born after IVF obtained significantly lower scores than the singletons in verbal IQ (containing information, picture & vocabulary, arithmetic, picture completion, comprehension, and language), performance IQ (containing maze, visual analysis, object assembly, and performance), and full scale IQ (P<0.05). The cognitive development of full-term singletons and twins born after ICSI did not show any significant differences. There was no significant difference between the parents of the singletons and twins in their characteristics where data were collected, including the age of the mothers, the current employment status, the educational backgrounds, and areas of residence. There were also no consistent differences in the duration of pregnancy, sex composition of the children, age, and height between singletons and twins at the time of our study although there existed significant differences between the two groups in the sex composition of the full-term children born after ICSI (P<0.05). Compared to the full-term singletons born after IVF, the full-term twins have lower cognitive development. The cognitive development of full-term singletons and twins born after ICSI did not show any significant differences. For all pre-term offspring, singletons and twins born after IVF or ICSI, the results of the cognitive development showed no significant differences.

For much of the twentieth century, parents in the United States with two children of the same sex were more likely to have a third child than were parents with one son and one daughter, that is, there was an effect of the sex of previous children on the occurrence of a third birth. Using multiple cycles of the Current Population Survey and National Survey of Family Growth, the authors examine the strength of this effect on both fertility behavior and intentions over multiple decades. Changes in the societal gender system are expected to weaken this pronatalist effect in recent periods. Consistent with this expectation, there has been some attenuation of the effect of sex composition of previous children on the third birth, suggesting declining salience of children's gender for parents.

IntroductionSon preference, an ongoing concern in India, is a known driver of ideal family size preferences and contraceptive use among couples. These associations can vary substantially with parity and can influence men and women differently. This study assesses the association of sex composition of children by parity and a) men's higher ideal family size preference relative to women and b) use of modern contraceptives by couples. MethodsWe used the Couples Recode dataset from National Family Health Survey (NFHS) 2015-16 and identified couples who had at least one child and had complete responses for variables used in the study (N = 56,731 couples). We developed multivariable linear and logistic regression models to study the association between sex composition of children by parity and our dependent variables. ResultsOur findings indicate that the sex composition of children is associated with men's higher ideal family size preference, relative to women, among couples with four or more children. We also find that couples with less than four children are less likely to use modern contraceptives when they have an equal or a greater number of daughters than sons compared to those who have no daughters. Findings suggest that couples with four or more children are more likely to use modern contraceptives when they have at least one son and one daughter and are less likely to use contraceptives when they have all daughters and no sons, than couples who have no daughters. ConclusionThis study contributes to existing research on the relationship between sex composition of children with ideal family size preferences and contraceptive use by highlighting meaningful differences between higher and lower parity couples. Findings from the study can be used by family planning programs in India to customize family planning counselling messages by both sex composition and parity.

Gender preference often results in low use of contraceptives and parity progression, which can increase the risks of morbidity and mortality for women. This study aimed to identify gender preference and fertility behavior, including contraceptive use and the desire for additional children, among married women. A cross-sectional descriptive study was conducted using systematic random sampling to select280 household, with one respondent interviewed from each household using a semi-structured interview schedule. Descriptive and inferential statistical analysis were performed on the collected data. Of 280 respondents, 44.6% were aged 26–35 years (mean30.23±7.39 years). Most (74.3%) were literate, and 70% were paid worker. Son preference was reported by 53%, with support in old age (87.2%) being the main reason. Gender preference was 60.5% less likely among Bramhin/Chhetri ethnic groups (p = 0.033) and 71.3% less likely if husbands were literate (p = 0.002). Contraception use was 90.7%, but 31.8% desired additional children. Permanent contraceptive method use was 9.387 times more likely above age 30 years (p = &lt;0.001), independent of respondents’ and husbands’ education, sex composition of children, and having a preferred child. Desire for more children was 6.813 times more likely below age 30 years (p = &lt;0.001) and 5.875 times more likely with 1–2 living children (p = 0.001), independent of respondents’ and husbands education.The study concludes that son preference persisted among the illiterate. Contraceptive use was lower among respondents below 30 years. Enhancing educational status may reduce gender bias. Targeting family planning to women below 30 years could improve contraceptive utilization in this age group.

Objective: To investigate the relationship between sex-composition of children and women’s fertility desire in Vietnam. Materials and methods: Using data from the 2014 Vietnam Multiple Indicator Cluster Survey (MICS), we investigate the association between sex composition of children and desire for additional children among women in reproductive age (15 to 49 years) across Vietnam (N=5,605).Results: Multivariate logistic regression models showed statistically significant association between sex composition of children and women’s fertility desire, after controlling for social norms of fertility preference, demographic and socioeconomic factors. For each group of women (those with one child, two children, and three or more children) women with no sons are more likely to have higher fertility desire compared to women with at least one son. However, women with both son (s) and daughter (s) tend to have lower fertility desire compared to those who have all sons.Conclusion: Vietnam’s traditional cultural norm of son preference has a strong influence on fertility desire. Besides, mix-gender preference is also documented. The government should enforce the law more strictly regarding the prohibition of ultrasounds to detect fetal sex to reduce the feasibility of sex selection abortion. In addition, the government should improve the social ideology of the role of women in the family and society through mass media.

This study examines the relationship between the husband's preference for a son, sex composition of children and risk of anaemia and underweight among married Indian women. Information was collected regarding 29,517 couples having at least one child in the nationally representative 2005-06 National Family Health Survey of India. The exposures were husband's preference for a son and sex composition of children: sons only, daughters only and mixed. Outcome included maternal underweight and moderate/severe anaemia. Husband's preference for a son was not found to be associated with his wife's risk of anaemia or underweight. Sex composition of the children was modestly associated with increased odds of anaemia among women from households with daughters only as compared with those with sons only [AOR: 1.19; 95% CI 1.04, 1.35]. The findings from this population-based study of socio-cultural norms around preference for a son and married Indian women's nutritional status do not support the hypothesis that husband's preference for sons influences the nutritional status of their wives. However, having daughters only is associated with maternal anaemia for reasons that remain to be established.

Although the effect of son preference on sex composition of children ever born is undetectable in national-level estimates that aggregate across all families, this article provides empirical evidence from India that son preference has two pronounced and predictable family-level effects on the sex composition of children ever born. First, data from India show that smaller families have a significantly higher proportion of sons than larger families. Second, socially and economically disadvantaged couples and couples from the northern region of India not only want but also attain a higher proportion of sons, if the effects of family size are controlled.

This study aims to explore the effect of son preference on the sex composition of children in Uttar Pradesh, India’s most populous state, using data from NFHS-IV (2015-16). While national-level estimates have been unable to detect the impact of son preference on the sex composition of children ever born across all families, this research seeks to uncover distinct and predictable patterns at the family level within Uttar Pradesh. The term son preference denotes a prevailing mindset wherein sons are accorded greater significance and value compared to daughters. By examining empirical evidence from Uttar Pradesh, this article highlights two primary effects of son preference on the children sex composition at the family level. Firstly, the data reveals that smaller families are significantly more likely to have sons, while girls tend to be found in larger households on an average. This suggests that families with a higher number of girl children tend to expand their size in an effort to have more sons. Secondly, the study confirms that son preference is associated with various factors, including the age of women, residence background, level of education, family structure, religion, survival status of the last child, and the sex of the last child born. Particularly, the preference for sons is found to be strongest among women, especially elderly women, with lower education levels, belonging to joint families, residing in rural areas of Uttar Pradesh, and being part of lower-caste and Muslim communities, and especially if their last-born child is female. Furthermore, it is established that when family size is controlled then characteristics of women/couples with strong son preference will be same as those women/couples with more sons and if family size is not controlled then the characteristics of women desiring a higher proportion of sons will slightly differ from those women who actually have a higher proportion of sons. These findings shed light on the complex interplay of cultural and socioeconomic factors that influence child sex composition and provide valuable insights for policy interventions aimed at addressing gender imbalances in Uttar Pradesh and beyond
