THE use of insecticides, perfumes, canned foods, and television has been identified as a significant cause of autism in children.

This statement was made by child specialist and researcher, Prof Karimu Manji, during his presentation on autism at the 13th Scientific Conference held at the Muhimbili University of Health and Allied Sciences (MUHAS) in Dar es Salaam.

Professor Manji explained that his research had shown that the use of insecticide sprays and perfumes significantly damages the child's brain, contributing to the onset of autism.

He further noted that the use of smartphones, tablets, and television by parents as a means to entertain or quiet children also plays a role in this condition.

“These practices, particularly for children under five, have serious health effects and contribute to autism. Parenting styles have changed, with parents increasingly using television and social media to silence children or keep them entertained while they focus on their own tasks,” Professor Manji stated.

He advised parents and caregivers to use the devices with caution and provided statistics showing that one in every 150 children is affected by autism, according to a study conducted in 2022.

Some symptoms of autism in children include difficulty in speech, repeating nonsensical phrases, embarrassment during communication, and negative behaviours or emotions.

Dr Omary Ubugoyu, assistant director of non-communicable diseases in mental health from the Ministry of Health, stated that the government aims to increase early autism detection through health centers and schools.

They have started in Dar es Salaam, launching a programme in 100 early childhood schools, where over 4,000 teachers will be trained to identify autism symptoms in children.

Additionally, they have expanded training for health workers to provide professional services for children with autism, with 50 experts already having completed the training.

Prof Appolinary Kamuhabwa, Vice Chancellor of MUHAS, noted that new degree programmes targeting children with autism have been introduced, including physiotherapy, speech therapy, and specialties focused on assisting children with physical disabilities.

Meanwhile, Prof Bruno Sunguya, Deputy Vice Chancellor of MUHAS for research and professional advisory, mentioned that April is designated as a month for raising awareness about autism.

“A child with autism is not disabled. If diagnosed early and treated properly, they can become skilled and reliable professionals within the community,” Prof Sunguya said.
