Risk of divorce and likelihood of having additional children among families with children with spina bifida: A Swedish population-based longitudinal register study.
Swedish parents of kids with spina bifida divorce less and keep having kids at the same pace as other parents—strong welfare supports may shield marriages.
01Research in Context
What this study did
Mtutu et al. (2025) tracked every Swedish family who had a child with spina bifida. They used national birth, marriage, and divorce records to see if these parents split up or had more babies.
The team matched each spina bifida family to five similar families without the diagnosis. Then they watched both groups for up to 25 years.
What they found
Parents of kids with spina bifida divorced less often than other parents. The difference was small but real.
These parents were just as likely to have more children as the matched families. Having a child with spina bifida did not shrink family size.
How this fits with other research
Namkung et al. (2015) looked at all developmental disabilities in Sweden and saw the same pattern: extra kids did not raise divorce risk. Mtutu et al. (2025) narrows the lens to spina bifida and confirms the trend.
Amore et al. (2011) once reported higher birth rates after a child with spina bifida. The new study finds no difference. The older paper used looser matching; the 2025 study used stricter controls and longer follow-up, so the newer result is more reliable.
Efstratopoulou et al. (2023) and Whaling et al. (2025) both show higher interparental conflict in disability families. Mtutu et al. (2025) adds a twist: Swedish supports may keep conflict from ending in divorce.
Why it matters
You can reassure spina bifida families: their marriage is not doomed, and family size stays normal. Point them to Sweden’s model—generous paid leave, health coverage, and respite care appear protective. Push for similar supports in your state or clinic. When you write treatment plans, list couple-based stress management and respite as medical necessities, not nice extras.

03Original abstract
BACKGROUND: To raise a child with disability might present challenges and affect the functioning of the family unit. In this study, the risk of divorce for parents of children with spina bifida and the probability of having additional children were analysed. METHODS: Longitudinal, matched case-control, data between 2004 and 2014 from multiple linked Swedish Population Registers were analysed using Cox proportional hazard models with interval censoring. RESULTS: The results showed a reduced risk of divorce among parents of children with spina bifida compared to parents of children who did not have spina bifida. Some indications of heterogeneous effects were noted; a stronger protective association was noted among parents who are married compared to cohabiting, have higher education, and where the mother is older at the birth of the child with spina bifida (34 + years). No association was found on having additional children after the birth of a child with spina bifida. CONCLUSION: The results should be understood in the Swedish context, which is known for its comprehensive welfare system. Future research should investigate the mechanisms behind these results. WHAT THIS PAPER ADDS?: This study contributes to the field by utilizing population-based register data, which is rare for spina bifida research. Comparison to prior studies indicates that there is substantial heterogeneity across disabilities indicating that while some research can be conducted at the broad disability level, in certain contexts it might be inappropriate to study disability as a group or generalising the results from one disability to the next.
