Patterns and determinants of short and long birth intervals among women in selected sub-Saharan African countries

Optimal birth spacing (defined as a birth spacing of 24-59 months) is incontrovertibly linked to better health outcomes for both mothers and babies. Using the most recent available Demographic and Health Survey data, we examined the patterns and determinants of short and long birth intervals among women in selected sub-Saharan African (SSA) countries.Reproductive health and sociodemographic data of 98,934 women from 8 SSA countries were analyzed. Unadjusted and adjusted multinomial logistic regression models were used to examine the net relationship between all the independent variables and short and long birth intervals.Overall, the majority of women in all the countries optimally spaced births. However, a significant proportion of women had short birth intervals in Chad (30.2%) and the Democratic Republic of Congo (Congo DRC) (27.1%). Long birth spacing was more common in Eastern and Southern African countries, with Zimbabwe having the highest rate of long term birth interval (27.0%). Women who were aged 35 years and above in Uganda (RRR = 0.72, CI = 0.60-0.87), Tanzania (RRR = 0.62, CI = 0.49-0.77), Zimbabwe (RRR = 0.52, CI = 0.31-0.85), Nigeria (RRR = 0.82, CI = 0.72-0.94) and Togo (RRR = 0.67, CI = 0.46-0.96) had significantly lower odds of having short birth intervals compared to women aged 15-24 years. Older women (above 34 years) had increased odds for long birth intervals in all countries studied (Chad (RRR = 1.44, CI = 1.18-1.76), Congo DRC (RRR = 1.73, CI = 1.33-2.15), Malawi (RRR = 1.54, CI = 1.23-1.94) Zimbabwe (RRR = 1.95, CI = 1.26-3.02), Nigeria (RRR = 1.85 CI = 1.56-2.20), Togo (RRR = 2.12, CI = 1.46-3.07), Uganda (RRR = 1.48, CI = 1.15-1.91), Tanzania RRR = 2.12, CI = 1.53-2.93).The analysis suggested that the determinants of long and birth intervals differ and varies from country to country. The pattern of birth spacing found in this study appears to mirror the contraceptive use and fertility rate in the selected SSA countries. Birth intervals intervention addressing short birth intervals should target younger women in SSA, especially in Chad and Congo DRC, while intervention for long birth spacing should prioritize older, educated and wealthy women.

Determinants of short birth interval among child-bearing age women in the Gedeb Hasasa district of the West Arsi zone, Ethiopia

Background

Short birth intervals have been linked to higher rates of fetal loss, prenatal mortality, and poorer child survival. Therefore, for countries like Ethiopia that have a population policy intended at reducing fertility, understanding the level and factors influencing birth spacing is crucial in order to apply appropriate intervention. This study aimed to assess the prevalence and determinants of the short birth interval among child-bearing age women in the Gedeb Hasasa district of the West Arsi zone, Ethiopia.

Methods

A community-based cross-sectional study was conducted from 20 July to 20 August 2018. A multistage sampling method was used. Face-to-face interviews were conducted to gather data. The collected data were entered into Epi Data version 3.1 and later exported to SPSS version 21 for analysis. Logistic regression was used to identify factors associated with the short birth interval. The level of significance was declared at a p-value of <0.05.

Results

A total of 714 women participated, with a 98% response rate. The median birth interval length was 32 months. The prevalence of the short birth interval was 50.4%. After adjusting for confounding variables, being a rural resident [AOR = 2.50, 95% CI (1.52, 4.09)], having an illiterate husband [AOR = 4.14, 95% CI (2.15, 8.45)], breastfeeding duration for 7-12 months [AOR = 3.16, 95% CI (1.95, 5.13)] and 13-23 months [AOR = 2.45, 95% CI (1.52, 3.95)], sex of the prior child [AOR = 0.63, 95% CI (0.45, 0.88)], and previous child alive [AOR = 0.20, 95% CI (0.14, 0.96)] were the determinants of short birth interval.

Conclusion and recommendation

One in every two women practiced short birth intervals. The median birth interval duration was 32 months, which is below the minimum standard recommended by the WHO duration for the birth interval, which is 33 months. Short birth intervals were determined independently by residence, husband education, breastfeeding time, previous child's sex, and previous child's survival. Therefore, increasing women's awareness of the ideal birth interval should be done through community health professionals and health developmental armies.

Factors associated with short birth interval among reproductive-age women in East Africa

BACKGROUND

Child and maternal mortality continue as a major public health concern in East African countries. Optimal birth interval is a key strategy to curve the huge burden of maternal, neonatal, infant, and child mortality. To reduce the incidence of adverse pregnancy outcomes, the World Health Organization recommends a minimum of 33 months between two consecutive births. Even though short birth interval is most common in many East African countries, as to our search of literature there is limited study published on factors associated with short birth interval. Therefore, this study investigated factors associated with short birth intervals among women in East Africa.

OBJECTIVE

To identify factors associated with short birth intervals among reproductive-age women in East Africa based on the most recent demographic and health survey data.

DESIGN

A community-based cross-sectional study was conducted based on the most recent demographic and health survey data of 12 East African countries. A two-stage stratified cluster sampling technique was employed to recruit the study participants.

METHODS AND ANALYSIS

A total weighted sample of 105,782 reproductive-age women who had two or more births were included. A multilevel binary logistic regression model was fitted to identify factors associated with short birth interval. Four nested models were fitted and a model with the lowest deviance value (-2log-likelihood ratio) was chosen. In the multivariable multilevel binary logistic regression analysis, the adjusted odds ratio with the 95% confidence interval was reported to declare the statistical significance and strength of association between short birth interval and independent variables.

RESULTS

The prevalence of short birth interval in East Africa was 16.99% (95% confidence interval: 16.76%, 17.21%). Women aged 25-34 years, who completed their primary education, and did not perceive the distance to the health facility as a major problem had lower odds of short birth interval. On the contrary, women who belonged to the poorest household, made their own decisions with their husbands/partners or by their husbands or parents alone, lived in households headed by men, had unmet family planning needs, and were multiparous had higher odds of having short birth interval.

CONCLUSION

Nearly one-fifth of births in East Africa had short birth interval. Therefore, it is essential to promote family planning coverage, improve maternal education, and empower women to decrease the incidence of short birth intervals and their effects.

Community Groups Co-Design Evidence-Based Docudramas to Communicate About Child Spacing in Bauchi State, Nigeria: A Qualitative Descriptive Study

In Bauchi State, northern Nigeria, communities recognise short birth interval (kunika in the Hausa language) as harmful, but family planning is a sensitive topic. This paper describes the development of a culturally safe way to communicate about kunika in a conservative Muslim setting. The objective was to co-design culturally safe communication material, based on local knowledge about short birth interval, to share with women and men in households.Six community co-design groups of women and six of men (total 96 participants) reviewed summaries of their previously created maps of perceived local causes of kunika, categorised as frequent sex, family dynamics and non-use of contraception. They advised how these causes could be discussed effectively and acceptably with women and their husbands in households and suggested storylines for three short video docudramas about the prevention of kunika. The research team created the docudramas with a local producer and fieldworkers piloted their use in households.The design groups advised that communication materials should focus on child spacing rather than on limitation of family size. Even sensitive issues could be covered. People would not change their sexual behaviour but could be advised to use contraceptives to prevent kunika. The groups approved the final videos and six focus groups of visited women and men reported they were acceptable and helpful. Community co-design of communication about kunika was feasible and led to videos about a sensitive topic that were acceptable to ordinary men and women in communities in Bauchi.
