“…Demographics were shown in Table . The proportion of males was significantly higher in the clinical group than in the mainstream group [ χ 2 (1154) = 52.017, P < 0.001], which was consistent with the male bias in the prevalence of ASD [Adak & Halder, ]. Children in the clinical group were slightly but significantly older than those in the mainstream group [ t (1154) = −4.254, P < 0.001].…”

“…Studies have also found sex differences in the patterns of autistic traits in the general population [Williams et al, ; Sun et al, ]. Furthermore, the prevalence of ASD shows a male bias (male–female ratio ≈4:1) [Adak & Halder, ], with a similar trend found in a population with high autistic traits [Constantino & Todd, ]. Consequently, diagnostic and assessment tools utilized to evaluate ASD or autistic traits have typically been developed based on samples containing more males.…”

Psychometric properties of the chinese version of autism spectrum quotient‐children's version: A sex‐specific analysis

A Simplified Chinese translation of the Autism Spectrum Quotient‐Children's Version (AQ‐C) is needed for research in mainland China. Autism Spectrum Disorder (ASD) is a condition that differs in presentation and prevalence by sex. Thus, evaluating the psychometric validity of the AQ‐C in males and females is an important step in its validation. The present study aims to develop a Chinese translation of the parent‐report AQ‐C, and test its psychometric properties among Mandarin Chinese speaking boys and girls. A total of 1,020 non‐clinical children and 134 children with ASD were assessed. Factor analyses were performed for the whole sample, as well as for girls and boys separately. A 30‐item, 5‐factor model (the Chinese AQ‐C) showed adequate goodness of fit (root mean square error of approximation [RMSEA] = 0.037; comparative fit index [CFI] = 0.907; Tucker‐Lewis index [TLI] = 0.901) for the whole sample. According to parents' reports, non‐clinical boys had significantly higher scores than non‐clinical girls on the Chinese AQ‐C. Sex‐specific factor structures were identified resulting in a 4‐factor model with 32 items for girls (the Chinese AQ‐Girls), and a 4‐factor model with 34 items for boys (the Chinese AQ‐Boys). The cut‐off scores of the Chinese AQ‐C, AQ‐Girls, and AQ‐Boys were 44.5, 42.5, and 46.5, respectively. These three Chinese versions of the AQ‐C all showed satisfactory internal consistency (α = 0.786–0.840) and concurrent validity with the Social Responsiveness Scale (r = 0.789–0.814) for the total scale. Differences have been found in the sex‐specific factor structures of the AQ‐C which would be more reliable to use for future research when measuring autistic traits in the general population.

Lay Summary This study developed Chinese versions of the Autism Spectrum Quotient‐Children's Version (AQ‐C) in Chinese boys and girls together and separately. The AQ‐C showed good psychometric properties in boys and girls together and separately. There were differences in sex‐specific factor structures of the AQ‐C. These results suggest that the sex‐specific Chinese versions of the AQ‐C provide reliable and valid measurement of autistic traits.

“…The review of Elsabbagh et al [8] presents the comprehensive tables of available figures of the autism and other pervasive developmental disorders prevalence in various geographic regions over the world in the period of the 1960s–2010. Fifty more studies from 21 countries published during 2000–2016 were analyzed [9], and 27 eligible studies from 18 countries on 5 continents were identified [71]. These reviews demonstrate that the prevalence rates of autism/ASD have increased over time in all investigated regions.…”

“…Many schemes have been operating there for over 50 years. A high ASD prevalence has been estimated to have been present in the UK since the 1990s (16.8–116 per 10,000) [8,9,71]. The National Autistic Society informs that there are around 700,000 people with ASD in the UK, which is more than one in 100 [92].…”

The continuous rise of autism spectrum disorder (ASD) prevalent in the past few decades is causing an increase in public health and socioeconomic concern. A consensus suggests the involvement of both genetic and environmental factors in the ASD etiopathogenesis. Fluoride (F) is rarely recognized among the environmental risk factors of ASD, since the neurotoxic effects of F are not generally accepted. Our review aims to provide evidence of F neurotoxicity. We assess the risk of chronic F exposure in the ASD etiopathology and investigate the role of metabolic and mitochondrial dysfunction, oxidative stress and inflammation, immunoexcitotoxicity, and decreased melatonin levels. These symptoms have been observed both after chronic F exposure as well as in ASD. Moreover, we show that F in synergistic interactions with aluminum’s free metal cation (Al3+) can reinforce the pathological symptoms of ASD. This reinforcement takes place at concentrations several times lower than when acting alone. A high ASD prevalence has been reported from countries with water fluoridation as well as from endemic fluorosis areas. We suggest focusing the ASD prevention on the reduction of the F and Al3+ burdens from daily life.

Autism can be considered both a personal and social identity. Identifying the factors contributing to positive Autistic identity development is crucial given the potential implications for mental health and wellbeing. In this systematic review, we aimed to synthesize quantitative literature on Autistic identity to identify the (individual and environmental) factors associated with Autistic identity, and to ascertain the relationship between Autistic identity and mental health and wellbeing. A total of 3,617 studies were screened and 20 met our inclusion criteria. Results indicated that people developed a more positive Autistic identity when receiving external autism acceptance and external support. The association between individual factors and Autistic identity were largely nonsignificant or inconclusive, highlighting the need for broad support that meets the needs of a range of Autistic people, rather than specific subgroups. Importantly, positive Autistic identity was associated with improved mental health and wellbeing. Peer support and/or self‐directed support resources may be valuable mechanisms for supporting Autistic people to cultivate a positive Autistic identity. The evaluation of such support, including the long‐term impacts on identity development, will be a critical avenue for future research.
