No, BBC, Racism is Not “Killing Black Mothers”

The BBC and other media outlets have publicised a disturbing claim in a Parliamentary report, that racism has played “a key role” in the deaths of pregnant women:

End racial disparities in maternal deaths – MPs

An MPs’ report is calling for faster progress to tackle “appalling” higher death rates for black women and those from poorer areas in childbirth.

The Women and Equalities Committee report says racism has played a key role in creating health disparities.

But the many complex causes are “still not fully understood” and more funding and maternity staff are also needed.

This is mostly based on a previous official report titled ‘Saving Lives, Improving Mothers’ Care‘. (They have added some interviews with mothers who felt that their concerns were ignored for racist reasons.)

The first thing to note is that pregnant mothers are very safe, with a death rate of six per 100,000. Even taking a year-long period, and including indirect causes, deaths are extremely rare. Suicide and drugs/alcohol are prominent causes of the few deaths recorded, with cardiac disease and Covid of equal impact. (Hatched bars show direct causes, solid bars indirect causes.)

So, for example, Covid was an indirect cause of death because it happened more widely and not because of pregnancy.

Half the causes of death are not obstetric. This should be a warning bell about the interpretations later placed on the data.

Later data show that the greatest predictor of later death was pre-existing medical problems including obesity. Obesity is also given as a primary cause. Not receiving advice is also noted as a cause, though it’s not clear if this can be due to not taking advice despite antenatal classes being offered. Some of the case histories mention this, and it would be relevant to understanding causes, and could be compared to the take-up of vaccinations.

Table 2.9 gives us the figures regarding race differences, the subject of media attention on the Parliamentary statement, but also prominent in the summary of the research report.

The numbers, mercifully, are small. Childbirth is safe in the U.K. The ‘White European’ results are the only ones sizeable enough to merit detailed examination, and they show that direct and indirect causes are of almost equal power, slightly favouring indirect. The racial group deaths are few, and some noise is to be expected.

To put this report into context, as regards U.K. ‘Black Caribbean’ mothers, we are talking about three direct deaths and six indirect, so nine in all. ‘Black Africans’ (who probably have spent more of their lives in Africa), are five direct, eight indirect, 13 in all. Combine the two, eight direct, 14 indirect. Tiny numbers, but favouring indirect causes.

Here are the calculations of rates per 100,000.

The rates per 100,000 differ considerably, but the base populations also differ considerably, and there are 18 times more whites than blacks. When events are very rare it is probably better to give absolute results, rather than relative risk odds ratios, which could be misleading.

In my view the main finding is that some mothers are unwell prior to childbirth, and often die for reasons not directly caused by childbirth. Some of those causes of ill health are self-imposed.

The Parliamentary group seems to have gone overboard on a racism explanation for which there is no evidence in this study. Indeed, there is virtually no data analysis in this report at all. They give the basic demographics, but few if any two-by-two tables. They do not show correlations, nor do they construct and test any explanatory models. Can they predict from their findings what puts women at risk? Drugs, drink, being overweight? Little from the authors on these necessary questions. A simple multiple regression on the total sample would have been instructive. The list of participants is impressive, the data analysis rudimentary, and the use of relative risk over-dramatic given the very big differences in sample sizes.

As is usual, they give stern lectures to service providers about the need to further educate themselves. They say less, if anything at all, about mothers keeping themselves healthy, for their own sake and their babies’.
