A new study warns couples rushing to get pregnant within two years of giving birth have a higher chance of having a child with autism. So, think wisely before planning your second baby.
The study, conducted by Centers for Disease Control and Prevention, showed a clear correlation between short birth spacing and autism.
According to the study, mothers who get pregnant within two years of their first baby are 50 percent more likely to have an autistic kid.
Women need at least 18 months to regain the healthy level of nutrients needed to carry and nourish a baby, the research stated.
Author Dr Laura Schieve used data from the Study to Explore Early Development, a multi-site case-control study with rigorous case-finding and case-classification methods.
The team reviewed data from 356 children with autism spectrum disorder, 600 with developmental disorders and 524 without any disorders. Given the scale of information collected, they were able to subdivide each autism case themselves based on the reported symptoms and assess maternal reproductive history.
They found that overly-long or overly-short birth spacing was uniquely correlated with autism and not with any other disorder.
Women wait at least 18 months to replenish the nutrients needed to carry a baby. Those who waited longer than the average tends to have fertility issues, the authors noted.
Dr Schieve noted that the findings support existing guidelines on pregnancy spacing and further highlight the association between autism and pregnancy health.
Couples thinking about getting pregnant should discuss pregnancy planning with a trusted doctor or healthcare provider, the researchers advised.
