Insights
Early child care practices like limited social interaction, reduced storytelling, and shorter breastfeeding duration are linked to autism risk in children aged 2-6. These factors, alongside lack of outdoor activities, indicate potential environmental influences on autism development.
Area of Science:
- Developmental Pediatrics
- Child Psychology
- Public Health
Background:
- Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
- Identifying early risk factors is crucial for timely intervention.
- Child care practices at home are considered potential environmental influences.
Purpose of the Study:
- To investigate early child care practices as potential risk factors for autism.
- To compare these practices between children with autism and typically developing children.
- To identify specific home-based factors associated with increased autism risk.
Main Methods:
- A case-control study involving 143 children diagnosed with autism (2-6 years) and 200 typically developing controls.
- Data collected via a structured questionnaire on early child care practices.
- Analysis focused on identifying significant associations between practices and autism diagnosis.
Main Results:
- Lack of outdoor activities showed a significant odds ratio (OR=3.36) for autism risk.
- Limited social play with peers (OR=19.57) was strongly associated with autism.
- Reduced storytelling/singing (OR=3.21) and breastfeeding duration of less than 6 months (OR=3.40) were also significant risk factors.
Conclusions:
- Early home child care practices, including social interaction, cognitive stimulation, and breastfeeding, are associated with autism risk.
- Specific factors like limited peer play, no outings, reduced storytelling, and short breastfeeding duration are identified as potential risk factors.
- These findings highlight the importance of supportive early home environments in child development and autism prevention.
Objectives:
To compare early child care practices at home as possible risk factors among children between 2 and 6 y of age with autism and a control group of normal children without any symptom of autism, presenting at the well-baby/immunization clinic.
Methods:
This case control study was undertaken at the autism clinic of CDC Kerala, comparing possible risk factors for autism among 143 children between 2 and 6 y with autism as per CARS criteria and a control group of 200 normal children of the same age from well-baby/immunization clinic of SAT hospital. The data was collected using a structured pre-piloted questionnaire, which included 11 questions administered by the same senior social scientist, on early child care practices at home that have been universally considered as important for child development.
Results:
On multivariate analysis on early child care practices at home as possible risk factors for autism, it was observed that statistically significant high odds ratios were present for (i) no outings (OR = 3.36; 95% CI: 1.39-8.16; p 0.007); (ii) child does not play with children of same age (OR = 19.57; 95% CI: 9.50-40.32); (iii) do not tell stories/sing songs to the child (OR = 3.21; 9 % CI: 1.61-6.41); and (iv) breastfeeding duration nil/ < 6 mo (OR = 3.40; 95% CI: 1.28-8.99).
Conclusions:
This case control study involving 143 children between 2 and 6 y with autism as per CARS criteria and a control group of 200 normal children has shown that early child care practices at home, specifically breastfeeding duration nil/ < 6 mo, child does not play with children of same age, do not tell stories/sing songs to the child and no outings for the child are possible risk factors for autism.
