The Communication Initiative
After nearly 28 years, The Communication Initiative (The CI) Global is entering a new chapter. Following a period of transition, the global website has been transferred to the University of the Witwatersrand (Wits) in South Africa, where it will be administered by the Social and Behaviour Change Communication Division. Wits' commitment to social change and justice makes it a trusted steward for The CI's legacy and future.
 
Co-founder Victoria Martin is pleased to see this work continue under Wits' leadership. Victoria knows that co-founder Warren Feek (1953–2024) would have felt deep pride in The CI Global's Africa-led direction.
 
We honour the team and partners who sustained The CI for decades. Meanwhile, La Iniciativa de Comunicación (CILA) continues independently at cila.comminitcila.com and is linked with The CI Global site.

DaVanzo, J., Hale, L., Razzaque, A., & Rahman, M. (2007). Effects of interpregnancy interval and outcome of the preceding pregnancy on pregnancy outcomes in Matlab, Bangladesh.  British Journal of Obstetrics and Gynaecology,114(9),1079-87

Abstract

Objective

To estimate the effects on pregnancy outcomes of the duration of the preceding interpregnancy interval (IPI) and type of pregnancy outcome that began the interval.

Design

Observational population-based study.

Setting

The Maternal Child Health–Family Planning (MCH–FP) area of Matlab, Bangladesh.

Population

A total of 66 759 pregnancy outcomes that occurred between 1982 and 2002.

Methods

Bivariate tabulations and multinomial logistic regression analysis.

Main outcome measures

Pregnancy outcomes (live birth, stillbirth, miscarriage [spontaneous fetal loss prior to 28 weeks], and induced abortion).

Results

When socio-economic and demographic covariates are controlled, of the IPIs that began with a live birth, those <6 months in duration were associated with a 7.5-fold increase in the odds of an induced abortion (95% CI 6.0–9.4), a 3.3-fold increase in the odds of a miscarriage (95% CI 2.8–3.9), and a 1.6-fold increase in the odds of a stillbirth (95% CI 1.2–2.1) compared with 27- to 50-month IPIs. IPIs of 6–14 months were associated with increased odds of induced abortion (2.0, 95% CI 1.5–2.6). IPIs ≥ 75 months were associated with increased odds of all three types of non-live-birth (NLB) outcomes but were not as risky as very short intervals. IPIs that began with a NLB were generally more likely to end with the same type of NLB.

Conclusions

Women whose pregnancies are between 15 and 75 months after a preceding pregnancy outcome (regardless of its type) have a lower likelihood of fetal loss than those with shorter or longer IPIs. Those with a preceding NLB outcome deserve special attention in counselling and monitoring.
