Insights
Serious neonatal infections, delivery complications, and maternal HIV infection are key risk factors for cerebral palsy in Botswana. Targeting maternal HIV can help reduce cerebral palsy incidence.
Area of Science:
- Neurology
- Pediatrics
- Public Health
Background:
- Cerebral palsy (CP) prevalence is higher in low-resource settings.
- Limited research exists on CP risk factors in these regions.
- Understanding unique risk factors can improve prevention and resource allocation.
Purpose of the Study:
- To identify risk factors for cerebral palsy in Botswana.
- To compare findings with those from high-resource settings.
Main Methods:
- A case-control study was conducted in Gaborone, Botswana (2013-2014).
- 56 children with cerebral palsy were compared to 56 age-matched healthy controls.
- Data collected via interviews, medical records, and physical exams; analyzed using logistic regression.
Main Results:
- Significant risk factors identified: neonatal infection (OR 15.0), delivery complications (OR 13.5), and maternal HIV (OR 3.5).
- Maternal HIV remained significant after adjustment (aOR 13.2).
Conclusions:
- Cerebral palsy risk factors in Botswana differ from high-resource settings.
- Maternal HIV infection is a key modifiable risk factor.
- Targeting maternal HIV may reduce cerebral palsy incidence in Botswana.
Background:
Although cerebral palsy is reported to have a higher prevalence in low-resource settings, there are few studies describing risk factors for cerebral palsy in these settings. A better understanding of the unique risk factors affecting children with cerebral palsy in low-resource settings could optimize both resource allocation and preventative strategies.
Methods:
A case-control study comparing children with cerebral palsy at ages two to 18 years with age-matched healthy control subjects was conducted between 2013 and 2014 at a referral center in Gaborone, Botswana. Study participants were enrolled from inpatient and outpatient settings, and data were collected through caregiver interviews, review of medical records, and physical examination of subjects. Risk factors were evaluated using conditional logistic regression models.
Results:
We studied 56 subjects with cerebral palsy and 56 age-matched control subjects. Significant risk factors for cerebral palsy included a history of serious neonatal infection (odds ratio 15.0, P = 0.009), complications during delivery (odds ratio 13.5, P < 0.001), and maternal human immunodeficiency virus (HIV) infection (odds ratio 3.5, P = 0.03). Maternal HIV infection remained a significant risk factor after adjusting for potential confounders and covariates (adjusted odds ratio 13.2, P = 0.05).
Conclusions:
Major risk factors for cerebral palsy in Botswana differ from those described in high-resource settings. Modifiable risk factors such as maternal HIV infection should be targeted as a potential strategy to reduce the incidence of cerebral palsy in Botswana. Further studies are necessary to determine optimal preventative and treatment strategies in this population.
