The trend of marriage, childbearing, and divorce and its determinants of socio-economic factors on divorce in Yazd province 2016-2021: A cross-sectional study

BACKGROUND: In recent decades, families and their stability as an important social institution have changed significantly. OBJECTIVE: This study aimed to investigate the marriage trends, childbearing, and divorce changes in Yazd province from 2016 to 2021 to estimate the effect of socioeconomic factors on divorce. MATERIALS AND METHODS: A cross-sectional study was done in 2 phases. In the first phase, an ecological (time trend) was conducted to investigate the 5 yr trend in the occurrence of marriage, childbearing, and divorce, as well as the factors affecting the occurrence of divorce in the second phase. For the second phase of the study, 600 participants were selected. 300 divorced and 300 married applicants were chosen between 2016 and 2021. A binary logistic regression model was used to find the related factors affecting the occurrence of divorce. RESULTS: The results showed a declining marriage (p = 0.05) and childbearing trend (p = 0.84), as well as an increasing trend in divorces (p = 0.02) in Yazd. Logistic regression analysis showed that college education (OR = 0.22, CI: 0.116-0.430, p [Formula: see text] 0.001) and being self-employed (OR = 0.48, CI: 0.255-0.934, p = 0.03) could reduce the odds of divorce. In addition, nonresidents (OR = 2.1, CI: 1.314-3.562, p [Formula: see text] 0.001), with [Formula: see text] 10-yr age differences (OR = 3.8, CI: 1.803-8.213, p [Formula: see text] 0.001) or the woman being older than her husband (OR = 3.4, CI: 1.981-5.848, p [Formula: see text] 0.001) could increase the odds of divorce. CONCLUSION: Our results confirmed that a combination of socioeconomic characteristics affects the stability of family institutions.
