As the condition is more prevalent in black women in the US and the UK, it has been suggested to be an explanation for the higher rate of preterm birth in these populations. It is opined that bacterial vaginosis before or during pregnancy may affect the decidual inflammatory response that leads to preterm birth. The condition known as aerobic vaginitis can be a serious risk factor for preterm labour; several previous studies failed to acknowledge the difference between aerobic vaginitis and bacterial vaginosis, which may explain some of the contradiction in the results. 
The limitations of these data must be understood by HCPs and parents. They include: small sample sizes with wide confidence intervals at 22 and 23 weeks GA, an unknown number of children with one versus multiple impairments, variation in the definition and labelling of NDD by HCPs (especially ‘severe’ versus ‘moderate’) that may not reflect parents’ views or reality, no information on mild or other types of impairment (., behavioural) and the lack of correlation between degree of NDD and QOL  . One example demonstrates such limitations clearly: A child with severe cognitive impairment and severe cerebral palsy and a child with isolated uncorrectable deafness would both be classified as having severe NDD.
