The rising demand for child care is putting a strain on parents of children with autism spectrum disorder (ASD), particularly the mothers. This study investigated Chinese mothers of children with ASD and examined the factors associated with maternal mental health. An online national survey was completed by the parents of 5077 ASD children and adolescents aged 0‍‒‍17 years. A total of 28.0% of the mothers reported poor mental health status. Mothers with children aged 10‍‒‍13 years had a lower chance of having poor mental health status than mothers with children aged 0‒2 years (odds ratio (OR) 0.63, 95% confidence interval (CI) 0.43‍‒‍0.91). Mothers of children with high-functioning autism were less likely to have poor mental health status than those of children with low-functioning autism (OR 0.76, 95% CI 0.62‍‒‍0.94). Having children with comorbidities was related with a higher risk of poor mental status (OR 1.56, 95% CI 1.35‒1.81), as were having conflicts with other family members (OR 1.44, 95% CI 1.22‍‒‍1.70) and providing full-time care (OR 1.22, CI 1.06‍‒‍1.41). A higher-than-average family income was associated with lower risk of having poor mental health status (OR 0.70, 95% CI 0.58‍‒‍0.82). Factors related to the children and family, and providing full-time care, have a significant effect on mothers' mental health status. Reducing obstacles to work and social interaction, as well as tackling the financial burden of raising an ASD child, may help improve the well-being of mothers.

The Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) (American Psychiatric Association, 2013) defines autism spectrum disorder (ASD) as a complex neurodevelopmental disorder that begins in early childhood and is accompanied by social communication deficits and repetitive stereotyped behaviors. According to the monitoring data released in 2021 in the United States, the prevalence of ASD in children was as high as 2.27%; that is, one in 44 children had autism (Maenneret al., 2021). China publicly reported this figure to be around 0.7% (Zhou et al., 2020). The current view is that children with ASD are generally impaired in their adaptation ability (McDonaldet al., 2016; Hodgeet al., 2021; Opertoet al., 2021). Adaptive behaviors comprise the conceptual, social, and practical skills that enable individuals to adapt to the environment, which play an important role in daily life (McDonald et al., 2019). "Adaptive behavior" was first described by Doll (1936). Subsequently, abnormalities in adaptive behavior were included in the criteria for intellectual disability for the first time (Heber, 1961). The American Association on Mental Retardation (AAMR) has refined and specified this term several times. Researchers hold different opinions on the structure of social adaptive capability. Greenspan and Granfield (1992) divided social adaptive capability into social understanding and social interaction. However, an increasing number of scholars considered that the concept of adaptive behaviors in children was constructed via multiple dimensions. The most representative one among them was the Vineland Adaptive Behavior Scales (VABS) proposed by Sparrow et al. (1984). This scale illustrates that adaptive behavior includes communication, daily living skills, socialization, and motor skills. Harrison and Oakland (2003) developed an Adaptive Behavior Assessment System (ABAS), by applying the theory of adaptive behavior proposed by AAMR and the American Association on Intellectual and Developmental Disabilities (AAIDD). This system shows that adaptive behavior has three adaptive composites, namely, conceptual composite (including communication, learning function, and self-management), social composite (including leisure and social skills), and practical composite (including community application, home living, health and safety, and self-care). As there are different requirements for the social adaptive capability of children from different cultural backgrounds and various regions, Chinese scholars have translated the Normal Development of Social Skills from Infant to Junior High School Children (S-M) scale compiled by Japanese scholars into Chinese, which is now widely used in China (Zhang et al., 1995). The impairment of adaptive function in children with ASD includes multiple dimensions, such as socialization, communication, and daily living skills (Kanne et al., 2011), and the degree of impairment can predict the prognosis and outcome in real life, including education acquisition and independent living ability (Farley et al., 2009). Therefore, adaptive behavioral capacity is considered to be a key intervention point that directly affects the individual and social outcomes of autistic children (Veenstra-VanderWeele et al., 2017; Bölte et al., 2019).

Autism spectrum disorder (ASD) is a serious neurodevelopmental impairment of children. Because of its difficulty of early diagnosis, length of disease course, irreversible injury and slim chance of curability, it brings heavy burdens to patients, their families and the whole society. Recent studies have shown that the pathogenic mechanism of ASD is closely related to the abnormal myelination caused by the imbalance of differentiation, proliferation and apoptosis of oligodendroglial lineage cells. This article will review on the role of oligodendroglial lineage cells in myelination and the mechanisms of ASD caused by improper differentiation, proliferation and apoptosis of oligodendroglial lineage cells, according to advanced researches. Oligodendrocytes play vital roles in neurodevelopment, and the defect in these cells has been recognized as one of the key pathogenic mechanisms leading to ASD. Elucidating the effects and disciplines which oligodendrocytes exert on the occurrence and development of ASD would provide guidance for precise prevention and control of neurodevelopmental disorders such as ASD.

OBJECTIVEThis study aimed to explore the association between periconceptional fish consumption by parents and autism spectrum disorder (ASD) and intelligence deficiency (ID).

METHODSA case-control study was conducted through a questionnaire with 108 ASD cases, 79 ID cases, and 108 controls. The ASD and ID cases were students from special educational schools in Tianjin from 2012 to 2014. The age- and sex-matched controls were from a high school, three primary schools, and a kindergarten in Tianjin. Multivariate logistic regression was performed.

RESULTSPaternal habit of eating hairtail before fertilization, maternal preference for fruits during pregnancy, and maternal habit of eating grass carp during pregnancy were preventive factors for ASD. Paternal habit of drinking alcohol before fertilization was a risk factor for ID, whereas maternal preference for fruits during pregnancy and maternal habit of eating crucian carp during pregnancy were protective factors for ID.

CONCLUSIONParental fish consumption is beneficial for the prevention of ASD and ID. Meanwhile, the protective effects of fish consumption on ASD and ID differ. More attention should be paid to the combined effect of other food when eating fish.
