Spina bifida refers to a collection of neural tube defects, including myelomeningocele, meningocele, and myelocele (SB(M) ), as well as lipomyelomeningocele and lipomeningocele (SB(L) ). Maternal race/ethnicity has been associated with an increased risk for spina bifida among offspring. To better understand this relationship, we evaluated different spina bifida subtypes (SB(M) vs. SB(L) ) and sub-phenotypes (anatomic level or presence of additional malformations) by maternal race/ethnicity using data from the National Birth Defects Prevention Study. This study is a large, multisite, population-based study of nonsyndromic birth defects. Prevalence estimates were obtained using data from spina bifida cases (live births, fetal deaths, and elective terminations) and total live births in the study regions. From October 1997 through December 2005, 1,046 infants/fetuses with spina bifida were delivered, yielding a prevalence of 3.06 per 10,000 live births. Differences in the prevalences of SB(M) vs. SB(L) , isolated versus non-isolated SB(M) , and lesion level in isolated SB(M) among case offspring were observed by maternal race/ethnicity. Compared to non-Hispanic (NH) White mothers, offspring of Hispanic mothers had higher prevalences of each subtype and most sub-phenotypes, while offspring of NH Black mothers generally had lower prevalences. Furthermore, differences in race/ethnicity among those with isolated SB(M) were more pronounced by sex. For instance, among male offspring, the prevalence of isolated SB(M) was significantly higher for those with Hispanic mothers compared to NH White mothers [prevalence ratio (PR): 1.55, 95% confidence interval: 1.23-1.95]. These findings provide evidence that certain spina bifida subtypes and sub-phenotypes may be etiologically distinct.
This research output has an Altmetric Attention Score of 18. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 09 February 2021.
All research outputs
#2,654,204
of 34,410,315 outputs
Outputs from American Journal of Medical Genetics. Part A
#117
of 4,743 outputs
Outputs of similar age
#16,447
of 302,079 outputs
Outputs of similar age from American Journal of Medical Genetics. Part A
#2
of 56 outputs
Altmetric has tracked 34,410,315 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 92nd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 4,743 research outputs from this source. They receive a mean Attention Score of 4.9. This one has done particularly well, scoring higher than 97% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 302,079 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 94% of its contemporaries.
We're also able to compare this research output to 56 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 96% of its contemporaries.
