<jats:p>
Autism is a neurodevelopmental condition characterized by differences in social interaction, communication and behaviour. Despite a global prevalence of one in 127 individuals, autism remains underdiagnosed in low-resource settings. We examined the epidemiology of autism among children aged 2 to 9 years in Northern Uganda. Using multistage sampling, 1,139 children were screened for neurodevelopmental conditions using the validated 23Q screening tool. Children who screened positive underwent clinical assessment, and suspected cases received specialist assessments according to

-5-TR criteria. Descriptive statistics and Firth logistic regression were employed for analysis. The mean age was 5.38 years (

= 2.07), and 51.0% were male. The prevalence of autism was 10.5 per 1,000 children (95% confidence interval [CI] [6.0, 18.5]), of whom 75.0% had co-occurring neurodevelopmental conditions. Autistic children were more likely to have intellectual disability, epilepsy, learning disabilities, global developmental delay, attention-deficit/hyperactivity disorder, dyslexia, cerebral palsy, hearing impairment and speech delay (

After adjusting for gender, family history of autism (adjusted odds ratio [aOR] = 6.95, 95% CI [1.60, 30.23]), teenage motherhood (aOR = 8.30, 95% CI [1.30, 53.12]), breech presentation (aOR = 12.23, 95% CI [1.83, 81.64]), and oxygen resuscitation at birth (aOR = 4.56, 95% CI [1.08, 19.33]) were independent predictors of autism. These findings highlight the need to strengthen early identification and targeted services for autistic children in low-resource settings.

Autism affects how people communicate, interact, and process information, and about one in 127 people worldwide are autistic. In low-resource settings, autism is often under-researched and underdiagnosed. We carried out a study in Northern Uganda to estimate how common autism is among children aged 2 to 9 years, to identify co-occurring neurodevelopmental conditions, and to explore factors that may increase likelihood of autism. We enrolled 1,139 children from diverse communities using a multi-step sampling process. After parental consent, one child per household was screened with the 23Q neurodevelopmental screener. Children with possible conditions received further assessment by trained health care workers, and likely cases were confirmed by specialist clinicians using

-5-TR diagnostic criteria. Approximately 1 in 95 children were autistic, and none had previously received a diagnosis of autism. The average age of the children diagnosed with autism was about 5 years, and slightly more than half were boys, and most lived in rural areas. Most autistic children (82%) had at least one additional neurodevelopmental condition, such as intellectual disability, learning delays, or epilepsy. Autism was linked to family history, teenage motherhood, and certain birth complications. Improving maternal care, community awareness, and early diagnosis could better support autistic children in Northern Uganda.
