“…16 However, the WHO guidelines are now more than 13 years old, and more recently issued guidance by healthcare organisations have suggested an interval of 18-24 months following a previous live birth may be optimal. [16][17][18] Previously published reviews have evaluated the impact of short IPI on neurodevelopmental disabilities and 19 nutritional status, 20 and the effect of IPI after a previous miscarriage on birth outcomes. 21 A recent systematic review of research from high-income countries (HICs) identified three studies evaluating the association between short IPI and perinatal death.…”

Background Interpregnancy interval (IPI) <6 months is a potentially modifiable risk factor for adverse perinatal health outcomes. Objective This systematic review evaluated the international literature on the risk of perinatal death associated with IPI. Search strategy Two independent reviewers screened titles and abstracts identified in MEDLINE, EMBASE and Scopus from inception to 4 April 2019 (Prospero Registration #CRD42018092792). Selection criteria Studies were included if they provided a description of IPI measurement and perinatal death, including stillbirth and neonatal death. Data collection and analysis A narrative review was performed for all included studies. Random effects meta-analysis was used to compare unadjusted odds of perinatal death associated with IPI <6 months and IPI ≥6 months. Analyses were performed by outcome of the preceding pregnancy and study location. Main results Of the 624 unique articles identified, 26 met the inclusion criteria. The pooled unadjusted odds ratio of perinatal death for IPI <6 months was 1.34 (95% CI 1.17-1.53) following a previous live birth, 0.85 (95% CI 0.73-0.99) following a previous miscarriage and 1.07 (95% CI 0.84-1.36) following a previous stillbirth compared with IPI ≥6 months. However, few high-income country studies reported an association after adjustment. Fewer studies evaluated the impact of long IPI on perinatal death and what evidence was available showed mixed results. Conclusions Results suggest a possible association between short IPI and risk of perinatal death following a live birth, particularly in low-to middle-income countries.

“…In a recent meta-study in pediatrics, the effects of birth spacing on one facet of personality were taken into consideration. Conde-Agudelo et al (2016) analyze the noncausal relationships of the birth gap and autism. Their conclusion is that short birth intervals are associated with an increased risk of autism spectrum disorder.…”

“…For this latter set of analyses, we separately examined subsets with an inter-pregnancy interval (IPI) of 18–59 months and an IPI of 60+ months. We did not combine these two groups because IPI of 60+ months has itself been found to be associated with ASD risk (Conde-Agudelo et al 2016). …”

Previous studies of associations between ASD and conception using assisted reproductive technology (ART) are inconsistent and few studies have examined associations with other infertility treatments or infertility disorders. We examined associations between ASD and maternal/paternal infertility disorders and numerous maternal treatments among 1538 mother–child pairs in the Study to Explore Early Development, a population-based case-control study. ASD was associated with any female infertility diagnosis and several specific diagnoses: blocked tubes, endometriosis, uterine-factor infertility, and polycystic ovarian syndrome. Stratified analyses suggested associations were limited to/much stronger among second or later births. The findings were not explained by sociodemographic factors such as maternal age or education or multiple or pre-term birth. ASD was not associated with ART or non-ART infertility treatments.
