First Time

The age of a woman when giving birth to her first child needs to be a concern because it is related to the safety of the mother and baby. A woman being too young or too old increases the risk of death for both the mother and baby. Every woman giving birth for the first time is likely to experience psychological disorders such as anxiety and excessive fear during labor, and even postpartum depression. Given the importance and possible extent of the consequences of women giving birth for the first time, this study intended to assess the factors that influence the age at first birth, especially amongst women of childbearing age in East Java. These factors include the age at first marriage, education, and region. The method used was the extended Cox regression model. The analysis shows that the age at first marriage and education are factors that significantly influence the age at first birth. The more mature the age at first marriage, the more mature the age at first birth. Likewise, the higher the educational status, the higher the potential for giving birth to a first child over the age of 23, especially amongst women who graduated high school and university.

Age At First Marriage

In this study an attempt has been made to examine the marriage to first birth interval and also to identify the socio-economic, demographic and cultural factors influencing the first birth interval among married women in Bangladesh. For this purpose the present study utilized the Bangladesh Demographic and health survey (Bdhs, 2004). Birth interval is major determinant of the rates of fertility. The average marriage to first birth interval of the respondent’s is observed to be 33.49 months. Independents test of chi-square and proportional hazards model are used to study the effect of selected background characteristics on first birth interval in Bangladesh. Accepted religion of respondent’s all of the independent variable has strong association with first birth interval. Result from proportional hazards model reveal that respondent’s education, access to mass media, age at first marriage, and use of contraception has highly significant impact on first interval excluding Rajshahi and Khulna division. Husband’s education is partially significant over first birth interval and childhood place of residence has little bit connotation on first birth interval.

This study examines the delay between first marriage and first live birth in China among a sample of women who married between 1980 and 1992. Most couples in China only use contraception after the first child is born. Most sample women had their first child within 2 years of marriage. However, there are significant rural–urban differences in the first birth interval, indicating that there was most probably deliberate fertility regulation after marriage among many urban couples. Survival analysis shows that place of residence, level of education, age at first marriage and marriage cohort affect the first birth interval.

Completed Family Size

The link between age at marriage and first birth in explaining completed family size is not always direct, due to heterogeneity in circumstances, that compel individual women to marry or initiate childbearing at a particular age. We analyzed data for 1020 women aged 45-49 in 2014 of the 1965-1969 birth cohort from the 2013-14 ZDHS. We fitted a bivariate and multivariate multinomial logistic regression to establish the effect of mother’s age at first marriage and at first birth on completed family size (CFS). Chi-square test of proportions measuring differences in proportions and relative risk ratios (RRR) with confident intervals at 95% are reported. Our results show that the average CFS was 6.7 (95% CI: 6.5 – 6.9) among women completing their reproductive span in 2014 with mean age at first marriage and birth being 18.3 years (95% CI: 18.0 – 18.5) and 18.9 years (95% CI: 18.7 – 19.1) respectively. Women marrying at younger ages and having their first birth at younger ages were more likely (RRR: 0.262; 95% CI:0.126-0.547 and RRR: 0.176; 95% CI:0.068-0.497 respectively) to have higher CFS than their compatriots that initiated both marriage and childbearing at or after age 22. Having no education, being a rural resident and having a medium household wealth all increased the risk of having higher CFS. Women that marry before age 19 have a higher likelihood of having 6 or more children by the end of their reproductive period. The study concludes that apart from a woman’s age at first marriage and first birth, a complex network of factors interact to determined CFS.

Women marrying at younger ages and having their first birth at younger ages were more likely (RRR: 1.187; 95% CI: 1.138–1.239 and RRR: 0.195; 95% CI: 0.074–0.511 respectively) to have higher CFS than their compatriots that initiated both marriage and childbearing at or after age 22 controlling for covariates as presented in the controlled model. The independent effects model shows that the risk of having 1–3 children compared to 6 or more children was lower (RRR: 0.073; 95% CI: 0.009–0.611; RRR: 0.136; 95% CI: 0,046-0.402 and RRR: 0.421; 05% CI: 0.135–1.312) for women whose ages at first marriage were < 15, 15–18 and 19–21 respectively relative to 22+. Women with 1–3 children were 2.5 times more likely to use contraception than women with 6 or more children. Conclusion Having no education, being a rural resident and having a medium household wealth all increase the risk of having higher CFS. Women that marry before age 19 have a higher likelihood of having 6 or more children by the end of their reproductive period.

Abstract Background Time-to-first birth after marriage has a significant role in the future life of each individual woman and has a direct relationship with fertility. This study aimed to see the determinant of time-to-first birth interval after marriage among Ethiopian women. Methods The data was obtained from 2011 Ethiopia Demographic and Health Survey which is the third survey. The sample was selected using a stratified; two-stage cluster sampling design and the data was analysed using parametric shared frailty model. Results A total of 7925 ever married women from the nine region of the country were included in this study. Of the total women, 5966 (75.3%) of them gave firstbirth. Age, residence area, employment status, contraceptive use and education of women were associated significantly to time-to-first birth. Conclusions Women having younger age at first marriage, urban women, contraceptive users had prolonged time to first birth interval. There is a need of teaching family for contraceptive use and improving women education to increase the length of first birth interval in Ethiopia.
