For years now, we – those of us in Western, capitalist countries – have been bombarded with messages about how dangerous bedsharing is. We get images of babies sleeping with knives or headboards as gravestones to remind us that bedsharing is the worst thing you can do.
It’s convenient as it places the burden of a baby’s death squarely on the shoulders of the parents. And in cultures that promote such independence, that shouldn’t be too surprising. After all, in the United States, for example, self-determination is one of the cornerstones for everyone. It doesn’t matter your origin, you are supposed to be able to make it on your own. (Let’s just ignore that the vast majority of people that “make” it have pre-existing privilege that they don’t want to talk about.)
The problem is that this is so simplistic and, as new research suggests, quite possibly very wrong.
Drs. Melissa Bartick and Cecilia Tomori co-author a new study that examined pre-existing data on SIDS and SUID for what is deemed “syndemics”. What is this? It is when two or more epidemics interact synergistically to contribute to the prevalence of or increase the risk for a disease or outcome in a specific population, in this case SUID. Specifically, syndemic theory treats disease not in isolation, but as part of the culture and social conditions of the groups affected. Let us look at the case of SUID and SIDS to better understand what is happening…
To understand how syndemic theory may explain SUID and SIDS, we have to first look at what the main predictors are. In almost all research we have: lack of breastfeeding, preterm birth, low birthweight, parental (but especially maternal) smoking, alcohol use, and lower health care access. What if now, we looked at how these factors cluster together in groups that are at high-risk or low-risk for SUID or SIDS? Well, this is exactly what Drs. Bartick and Tomori have done in their latest article. It should probably come as no surprise to anyone that these other factors do cluster. Groups with a higher prevalence of SUID and SIDS happen to have multiple risk factors, but the overarching link for all of these is poverty. And it’s not just poverty, but the degree of discrimination that these families face daily also predicts some of these risky health behaviours, like smoking and alcohol use. This is why we see clusters of populations who are particularly vulnerable to SUID and SIDS, regardless of bedsharing rates.
Now, before we include bedsharing in this, let’s first acknowledge that the risk for bedsharing is actually quite debatable and there is a fair bit amount of research that suggests bedsharing is either not a factor when done intentionally, is not a factor when missing other risk factors (like the aforementioned), is protective past 4 months of age, and is intricately related with breastfeeding which is protective of SUID and SIDS, which poses some issues when trying to look at normal parental behaviours. Good, with that said, let’s look at how bedsharing factors into the above.
The bedsharing part comes in here because many of these disadvantaged groups do bedshare on a regular basis. Why the authors are able to tease this apart is that so do many groups with some of the lowest SUID and SIDS rates. It’s the other factors that have changed. For example, Sweden had the highest rate of bedsharing in their review of all Western countries, but also had one of the lowest rates of SUID. They also, of course, have high breastfeeding rates, universal health care (which equals good prenatal care), parental leave, and low smoking rates. In this environment, bedsharing is not a factor for SUID or SIDS.
Contrast this to the Black population in the United States where bedsharing is also more prevalent than for non-Hispanic White populations, but in line with the Asian/Pacific Islander US population. Blacks have a SUID rate of 1.88 per 1000 live births compared to 0.90 in the US White population and 0.41 in the US Asian/Pacific Islander population. Although bedsharing does increase compared to Whites, it is no different than that of the US Asian/Pacific Islander population, but what is different are the rates of other key variables, smoking, alcohol intake, lack of prenatal care, higher rates of preterm birth, and lower rates of breastfeeding. If you then factor in the effects of stress from ongoing systemic racism and historical trauma (which has been studied and isn’t just some made-up thing, check out ), you have a perfect storm for an increased risk of something like SUID or SIDS.
I’ve shared two examples, but their paper is a look at much more than this and is critical for all to read and acknowledge if we are going to try to alleviate the burden and trauma of SUID and SIDS. Drs. Bartick and Tomori acknowledge that there is still much to learn as understanding the relationships between these areas is still gray, but we have to start moving on removing these systemic barriers to healthy babies, as they aptly point out, not just for babies, but for the well-being of our society.
It may all sound quite simple – of course poverty, SES, historical trauma and everything associated with these factors influences infant mortality of all kinds! – but it’s actually quite difficult. It forces us in Western cultures with a strong belief in self-determination to step back and acknowledge our own personal limitations in helping save our babies. Bedsharing is an easy scapegoat that gets to place the burden on families, but it’s one that just doesn’t hold under closer scrutiny. Unfortunately in life things are rarely so simple and even more unfortunately, we are at the whim of the cultural structures we inherit at birth and their impact on our lives. We have to accept – much to our chagrin – that we need others to help us keep our babies alive (and so much more).
What this means for us as individuals is that we all have a role to play in reducing SUID and SIDS, but not by berating families not to bedshare, but by doing all we can to create a society that supports everyone. The problem some of us can have now is how we as individuals tackle what is now a systemic problem. Here are some ideas:
- Join movements in your area that focus on the issues facing marginalized and minority groups, even if you are in the majority. Just be prepared to listen to them on what they need from you and others and be prepared to act.
- Speak out against injustice when you see it. Passivity is simply unspoken support.
- Join your local LLL and focus on their work to expand breastfeeding support to marginalized and poorer communities.
- Donate to non-profits that work to provide prenatal care to those who do not have access or, if you are a medical professional, join one of these non-profits and provide some medical care to those in need.
- Advocate to your government for the following:
- Increases in cost of tobacco (which is a strategy to help reduce tobacco use)
- Improve parental leave policies
- Expand any government-sponsored health coverage to include pregnant women and their babies
- Find affordable and safe housing for pregnant women and young families
- Ask a friend who is a part of a marginalized group what you can do specifically to support them as they welcome a new baby. They may not have a social safety net, but if they have one of friends, that can make a large difference as well.
I don’t believe this will be a quick fix, but I can guarantee that no matter where you live, a lot more could be done and you can – and should – be a part of it.
