Age at First Marriage and Fertility Decline in Dabat Health and Demographic Surveillance System Site, Northwest Ethiopia: Decomposition Analysis

Abstract Background: Fertility declines in Ethiopia have been documented since 1990s. Amhara National Regional State has recorded the most noticeable fertility decline. However, specific factors that explain the incipient course of fertility decline in the study area and their relative contributions were not well investigated. Hence, the purpose of this study was to determine the factors that contributed for fertility decline, and to assess the variations in fertility that can be attributed to both changes in characteristics and reproductive behaviors of women aged 15–49 years between 2008 and 2014 in Dabat Demographic and Health Surveillance System Site, Northwest Ethiopia.Methods: Cross sectional censuses were carried out in Dabat Health and Demographic Surveillance System site in 2008 and 2014. Data for 4,775 and 10,807 women with reproductive age in 2008 and 2014 were used for the analysis. Poisson regression model was employed to assess the trends of determinants of fertility, and Multivariate Decomposition technique was applied to evaluate observed changes in fertility using data from two consecutive cross-sectional censuses of Dabat HDSS conducted in 2008 and 2014.Results: The findings indicated that there was a reduction of an average 640.69 births per 1,000 women of the reproductive age during the year 2014 compared to the year 2008 in the surveillance site (P-value <0.001; 95% CI: -669.5 to -582.4). This overall change in fertility during the study period was attributed to both changing characteristics of women (the distribution effect) (76%) (P-value < 0.001; 95%CI: -524.74, -453.13, and their reproductive behavior (the effect shown by regression coefficients of the variables on the outcome) (24%) (P-value <0.001; 95% CI: -224.36 to -79.14). The drivers of the recent fertility decline during the study period were the shift observed in the age at first marriage, the change in the proportion of currently married women, the shift in women’s birth to later age and the change in women's educational status.Conclusion: This study indicated that the overall reduction in fertility was attributed to both changing characteristics of women and their reproductive behavior. The major contributors to the changes in fertility were the postponing of women’s first marriage to later age and the change in the proportion of currently married women over the study period. Encouraging women to complete at least secondary education are important to increase the age at first marriage and birth which intern accelerate the current fertility transition.

SummaryAccording to the 1991/92 Tanzania Demographic and Health Survey, a Tanzanian woman has, on average, 6·1 births before she reaches age 50, a decline of about one birth per woman since the early 1980s. The major proximate determinant of fertility is universal and prolonged breastfeeding. An analysis of the social and demographic correlates of fertility shows that infant and child mortality, level of education and age at first marriage are among the factors which significantly influence fertility in Tanzania.

ABSTRACTObjectivesTo describe temporal trends in child marriage between 1990 and 2019 in a rural sub-district of Bangladesh and characterize relationships between age, time to pregnancy, complications during delivery, and perinatal mortality.DesignHealth and demographic surveillance system.SettingBaliakandi sub-district, Bangladesh.Participants56,155 female residents.Main outcome measuresAnnual proportion of marriages to female residents under 18 years of age, time between first marriage and pregnancy, proportion of births with complications during delivery, and odds of perinatal mortality.ResultsBetween 1990 and 2010, the proportion of marriages to female residents under 18 years of age decreased from 71% to 57%. Most notably, marriages to females aged 10 to 12 years dropped from 22% of all marriages to 3%. In 2019, 53% of all marriages were to females under 18 years. The estimated time between first marriage and pregnancy did not differ by female age at marriage. By 365 days after marriage, the cumulative incidence of pregnancy was approximately 50% for each age group. Adolescent girls were more likely to experience complications during delivery with at least one complication reported for 36% of mothers aged 13 to 15 years, 32% of mothers aged 16 to 17 years, and 23% of mothers aged 18 to 34 years (χ2 test, P<0.001). Compared to adults, births among females aged 13 to 15 years were more likely to result in stillbirths (odds ratio 2.23, 95% confidence interval 1.19 to 4.16) and births among females 16-17 years were more likely to result in early neonatal deaths (odds ratio 1.57, 95% confidence interval 1.01 to 2.42).ConclusionsChild marriage persists in Baliakandi. Over half of all marriages were to child brides and only minor reductions were seen over the past decade. Pregnancies were common among adolescent girls with no evidence of delayed pregnancy after marriage. Compared to adults, adolescents were more likely to experience complications during delivery and perinatal death. Preventing child marriage has substantial social and health benefits for girls and, by doing so, will also contribute to Bangladesh’s commitment to reduce child mortality.

ObjectiveThe main objective of this study was to investigate the magnitude and associated factors of non-communicable chronic diseases (NCDs) at the Dabat Health and Demographic Surveillance System (DHDSS) site in the northwestern part of Ethiopia.DesignA population-based cross-sectional study was conducted from October to December 2014.SettingHDSS site, Ethiopia.ParticipantsA total population of 67 397 living in 16 053 households was included in the study.MeasuresStructured interviewer-administered questionnaire was used to collect data. Self-reported morbidity was used to ascertain NCD. A binary logistic regression model was employed to identify the determinants of NCDs.ResultOne thousand one hundred sixty (1.7%) (95% CI 1.62 to 1.82) participants were found with at least one type of NCD. Heart disease and hypertension which accounted for 404 (32.2%) and 401 (31.9%), of the burden, respectively, were the most commonly reported NCDs, followed by 347 (27.7%) asthma, 62 (4.9%) diabetes mellitus and 40 (3.2%) cancer cases. Advanced age (≥65 year) (adjusted OR (AOR)=19.6; 95% CI 5.83 65.70), urban residence (AOR=2.20; 95% CI 1.83 to 2.65), household food insecurity (AOR=1.71; 95% CI 1.37 to 2.12) and high income (AOR=1.28; 95% CI 1.02 to 1.59) were significantly associated with the reported history of NCDs, whereas low (AOR=0.36; 95% CI 0.31 to 0.42) and moderate (AOR=0.33; 95% CI 0.22 to 0.48) alcohol consumption, farming occupation (AOR=0.72; 95% CI 0.57 to 0.91), and work-related physical activities (AOR=0.66; 95% CI 0.50 to 0.88) were inversely associated with NCDs.ConclusionThere is a high burden of NCDs at the Dabat HDSS site. Promotion of regular physical exercise and reducing alcohol consumption are essential to mitigate the burden of NCDs. In addition, preventive interventions of NCDs should be strengthened among urban dwellers, older age people and people of higher economic status.

The decline of American fertility on a national scale is a well-known and well-documented phenomenon, but little is known about fertility decline at the community level. Are immigrant groups really different or are they affected by the same factors and respond to them in the same manner as native-born populations? This essay investigates the fertility and nuptiality experience of the Wends of Serbin, Texas using age-specific fertility rates, total marital fertility rates, the index of family limitation, age at last birth, birth intervals and age at first marriage for both males and females. The Wends are shown to have experienced fertility decline in the same magnitude as the rest of the country though they begin and end at higher levels.
