Based on nutritional and parasitological examinations of 389 children aged 10-13 years in five primary schools in the schistosomiasis endemic Dongting Lake region of China, the causal factors of their retarded growth, represented by height, weight, mid-upper arm circumference and body mass index, were investigated. Among the four parasites, schistosomiasis infection due to Schistosoma japonicum played a significant role, with higher rates in girls than in boys. Praziquantel treatment of schistosomiasis decreased the infection rate and improved the children's growth. For dietary intake factors, the contribution of protein to total energy intake, which was lower in girls than in boys, had the greatest effect on the growth patterns. The sex difference in growth retardation is judged to be attributable to the traditional norms, such as girls spending more time in infested environments and gender discrimination in food distribution.
基于对中国血吸虫病流行的洞庭湖区五所小学389名10至13岁儿童的营养和寄生虫学检查，对以身高、体重、上臂中部周长和体重指数为代表的生长发育迟缓的病因进行了调查。在四种寄生虫中，日本血吸虫引起的血吸虫病感染起了重要作用，女孩的感染率高于男孩。吡喹酮治疗血吸虫病降低了感染率，改善了儿童的生长发育。对于饮食摄入因素，蛋白质占总能量摄入的比例对生长模式影响最大，女孩该比例低于男孩。生长发育迟缓的性别差异被认为归因于传统规范，比如女孩在受感染环境中花费更多时间以及食物分配中的性别歧视。
