The number of people diagnosed has increased considerably since the 1990s, which may be partly due to increased recognition of the condition.While rates of ASD are consistent across cultures, they vary greatly by gender, with boys diagnosed far more frequently than girls: 1 in 70 boys, but only 1 in 315 girls at eight years of age. Girls, however, are more likely to have associated cognitive impairment, suggesting that less severe forms of ASD are likely being missed in girls and women. Prevalence differences may be a result of gender differences in expression of clinical symptoms, with women and girls with autism showing less atypical behaviors and, therefore, less likely to receive an ASD diagnosis.Using DSM-5 criteria, 92% of the children diagnosed per DSM-IV with one of the disorders which is now considered part of ASD will still meet the diagnostic criteria of ASD. However, if both ASD and the social (pragmatic) communication disorder categories of DSM-5 are combined, the prevalence of autism is mostly unchanged from the prevalence per the DSM-IV criteria. The best estimate for prevalence of ASD is 0.7% or 1 child in 143 children. Relatively mild forms of autism, such as Aspergers as well as other developmental disorders, are included in the DSM-5 diagnostic criteria. ASD rates were constant between 2014 and 2016 but twice the rate compared to the time period between 2011 and 2014 (1.25 vs 2.47%).
Potassium phosphate is a generic term for the salts of potassium and phosphate ions including:
Monopotassium phosphate (KH2PO4) (Molar mass approx: 136 g/mol)
Dipotassium phosphate (K2HPO4) (Molar mass approx: 174 g/mol)
Tripotassium phosphate (K3PO4) (Molar mass approx: 212.27 g/mol)As food additives, potassium phosphates have the E number E340. == References ==
