Health facility-based prevalence and potential risk factors of autism spectrum disorders in Mali

Background: The prevalence of autism spectrum disorders (ASD) is 1-2% worldwide, 1 in 68 in the U.S, and unknown in Africa. ASD is under-diagnosed in Mali due to stigma and the lack of appropriate human resources and infrastructure.Objective: To determine the ASD frequency and potential risk factors in Mali.Methods: We identified all the health facilities and community-based organizations involved in the ASD diagnosis and management in Bamako. We established an ASD research and awareness platform in Mali, which encompasses community-based organizations and a multidisciplinary team including psychiatrists, psychologists, pediatricians, geneticists, and public health and social science specialists. Through this platform, we performed a survey in health facilities and organizations where patients with ASD are likely to seek care in Bamako. We reviewed the psychiatric patient registry to obtain basic epidemiological profiles of children with ASD, epilepsy and other psychiatric disorders.Results: We found a health facility-based prevalence of ASD of 4.5% (105/2,343) in Bamako. The mean age at the first outpatient visit was 7.64 ± 3.85 years old. First degree consanguinity of 29.5% (31/105) was more frequent in parents of ASD children versus age and sex matched controls OR= 4.37 [1.96-9.76] p=0.0001.Conclusion: Our data suggest that ASD is more common than expected in Mali. The established ASD awareness and research platform may improve the diagnosis and management of ASD by raising ASD awareness, training of Malian clinicians and researchers in early ASD screening and diagnosis, and strengthening research capacity in genomics of ASD and other mental disorders.Keywords: ASD, prevalence, consanguinity, health facilit

Mental health capacity building in Mali by training rural general practitioners and raising community awareness

International audienceIntroduction: despite the high prevalence and significant burden of mental disorders, they remain grossly under-diagnosed and undertreated. In low-income countries, such as Mali, integrating mental health services into primary care is the most viable way of closing the treatment gap. This program aimed to provide a mental health training intervention to rural general practitioners (GPs), to organize community awareness activities, and to evaluate the impact on mental health knowledge and through the number of new patients diagnosed with mental disorders and managed by these general practitioners. Methods: a pre-test/post-test design and the monthly monitoring of the number of new patients diagnosed with mental disorders by the trained GPs were used to evaluate the effect of the training interventions (two face-to-face group training workshops followed by individual follow-up supervisions) and of the community awareness activities. Results: the mean knowledge score of the 19 GPs who completed the initial 12-day group training raised from 24.6/100 at baseline, to 61.5/100 after training (p<0.001), a 150% increase. Among them, sixteen completed the second 6-day group training with a mean score increasing from 50.2/100 to 70.1/100 (p<0.001), a 39.6% improvement. Between July 2018 and June 2020, 2,396 new patients were diagnosed with a mental disorder by the 19 GPs who took part in the program. Conclusion: despite limited data regarding the effect of the community awareness component at this stage, the findings from this study suggest that the training intervention improved GPs' knowledge and skills, resulting in a significant number of new patients being identified and managed

Validation of two parent-reported autism spectrum disorders screening tools M-CHAT-R and SCQ in Bamako, Mali.

BackgroundEarly screening is crucial for early autism spectrum disorders (ASD) diagnosis and intervention. ASD screening tools have mostly been constructed based on the Western cultural context. We hypothesized that their use in Mali may require a prior validation.ObjectiveTo validate the modified checklist for autism in toddlers-Revised (M-CHAT-R) and the social communication questionnaire (SCQ) in the Malian sociocultural context for ASD screening.Study designWe administered M-CHAT-R and SCQ in 947 toddlers aged 16-30 months old at the district and community health centers in Bamako and 120 patients (60 autistic and 60 age and sex matched controls) aged ≥4 years old at the psychiatry department in Bamako. Toddlers at moderate to high risk of ASD underwent M-CHAT-R/F and clinical evaluation by an ASD multidisciplinary team. M-CHAT-R and SCQ were evaluated for cultural appropriateness by Malian anthropologists. The sensitivity, specificity, PPV, NPV were determined for both M-CHAT-R and SCQ. Health professionals have been trained during ASD seminary on how to use M-CHAT-R and SCQ for ASD screening in Bamako.ResultsWe found for the M-CHAT-R a sensitivity of 50%, a specificity of 100%, a PPV of 100% and a NPV of 87%. The SCQ had a sensitivity of 71%, a specificity of 72%, a PPV of 73% and a NPV of 70%. We have found four out of 20 items on the M-CHAT-R that were culturally inappropriate in the Malian context.DiscussionM-CHAT-R and SCQ can be used for early autism screening in Mali. In the future, we plan to train a descent number of Malian physicians in chief and pediatricians at the district hospitals across the country to integrate the early ASD screening into the national health system.ConclusionM-CHAT-R has a perfect specificity and SCQ a fair diagnostic accuracy for ASD in Mali
