Clonorchiasis is caused by raw-freshwater fish-eating practice and causes high burden in Asia. Transmission mechanism of this behavior hasn't been illuminated, which hinders the adoption of sustainable control activities. A cross-sectional survey was implemented in students from four endemic provinces in China. Data with 23,222 students aged 9–18 and their parents were eligible. Familial clustering of raw-eating practice, impact of parents' practice on children, interaction of spouses' practice was analyzed. Raw-eating practice met β-binomial distribution (χ2 = 0.8, p>0.05). Clustering coefficient increased by students' age (R2 = 0.82, p<0.001) and was higher in those families with boys compared to girls (t = 4.1, p<0.01). The proportion of students with raw-eating practice increased yearly by 8.9% in girls and 10.5% in boys. Compared to those without parents' raw-eating practice, adjusted odds ratio of students' raw-eating practice was 10.5 (95% confidential intervals (95% CI): 9.4–11.7) in those with fathers' practice, 33.6 (95% CI: 26.3–42.9) in those with mothers' practice and 47.1 (95% CI: 42.0–52.8) in those with both parents' practice. There exists interaction between spouses' practice (χ2 = 6713.1, p<0.001) and the impact from husband on his wife was higher than that from wife on her husband. Familial assimilation characterizes the transmission of raw-freshwater fish-eating practice, consisted of vertical intergenerational assimilation from parents to their children and horizontal martial assimilation between spouses. A sustainable strategy against clonorchiasis should interrupt the transmission of raw-freshwater fish-eating practice. Additionally, further studies are expected to explore more information, e.g. the frequency in raw-eating practice and type of raw freshwater fish, infection status of C. sinensis in participants, as well as direct collection of parents' eating information from themselves. Author summary: Clonorchiasis is caused by the ingestion of raw freshwater fish, which contains the infective larvae of Clonorchis sinensis. It is highly endemic in Asia, where about 15 million people are afflicted. To establish sustainable control strategy, the transmission of raw-eating practice needs to be illuminated. In this study, we conducted a survey in school students from four clonorchiasis endemic provinces in China, covering 23,222 students aged 9–18. The characteristics of raw-eating practice, impact of parents' raw-eating practice on children, interaction of spouses' practice was explored. It is demonstrated that raw-eating practice presents familial clustering, which is higher in those families with older children and with boys. Raw-eating practice in children is highly influenced by their parents' raw-eating practice especially when both parents do. Additionally, there exists interaction between spouses' raw-eating practice. The impact of husband's raw-eating practice on his wife is higher than that of wife's raw-eating practice on her husband. Familial assimilation dominates the transmission of raw-freshwater eating-practice, including the assimilation from parents to their children and that between spouses. This finding indicates the adoption of sustainable strategy against clonorchiasis through blocking raw-freshwater fish-eating practice. [ABSTRACT FROM AUTHOR]

Background: Cysticercosis is spreading all over the world and it is a major health problem in most countries of Latin America, Africa, and Asia. Extensive disseminated cysticercosis is relatively rare and fewer than 120 case have been reported in the worldwide. We reported a rare case of extensive disseminated cysticercosis in Yunan province, China.Case Presentation: A rare case of extensive disseminated cysticercosis, in a 61-year-old male Chinese was detected from Yunnan province in 2018. Clinical and etiological examination was performed, as well as the epidemiological investigation.Conclusion: The life cycle of T. solium in the area where the case came from is complete. We expect this case could raise the attentions to the control of Taenia solium infection and subsequent cysticercosis there. [ABSTRACT FROM AUTHOR]

Background: Moderate-to-vigorous physical activity (MVPA) and television viewing are independently associated with cardiorespiratory fitness. However, limited evidence is available on their combined effects, specifically of MVPA and watching television, on cardiorespiratory fitness in the young Asian population. Therefore, the present study examined whether MVPA can attenuate the detrimental effects of prolonged television viewing on the cardiorespiratory fitness of Asian adolescents., Methods: This is a cross-sectional study on 9553 adolescents (aged 12-15 years) from 8 Asian metropolitan cities (Tokyo, Hong Kong, Shanghai, Taipei, Bangkok, Kuala Lumpur, Seoul, and Singapore). Cardiorespiratory fitness was assessed by using a 15-m progressive aerobic capacity endurance run (PACER) test. The time spent on MVPA and watching television was assessed using the International Physical Activity Questionnaire-Short Form., Results: MVPA was more closely associated with the PACER score than the duration of watching television. Compared with the reference group (i.e. those with the lowest levels of MVPA [< 30 min/day] and the most sedentary [≥3 h/day of television time]), PACER scores were significantly higher for those who met the physical activity recommendation (≥60 min/day in MVPA), regardless of the duration of television viewing. Conversely, girls in the least active group (< 30 min/day of MVPA) who watched television < 1 h/day demonstrated better PACER scores than the reference group., Conclusions: Sufficient MVPA (≥60 min/day) can attenuate the detrimental effects of excessive television viewing with cardiorespiratory fitness in Asian adolescents. In addition, the duration of television viewing had significant but weaker associations with cardiorespiratory fitness compared to MVPA.
