Objective: To understand the prevalence of sexual abuse among rural children and its association with family cohesion and adaptability, and to explore factors that may affect household functions of the victims. Methods: A total of 1 666 rural middle school students in Hanchuan and Yunxi, Hubei were recruited with stratified cluster sampling method, multivariate Logistic regression was used to analyze associated factors of the household functions of the victims. Results: A total of 175 (10.50%) reported non-contact sexual abuse and 44 (2.64%) reported contact sexual abuse. Compared with control group, sexual abuse victims reported lower scores of family cohesion (F=8.97，P<0.01) and adaptability (F=4.09，P=0.02). Among the victims, maternal absence was a risk factor for poor family cohesion(OR=0.20，P<0.01), higher parental educational level and appropriate parenting methods(P<0.05) were protective factors for family cohesion and family adaptability. Conclusion Household functions of children sexual abuse victims in rural areas are generally poor, especially for victims with mothers absence, low parental education and improper parenting style. More attention should be paid to such children to minimize the impact of negative events such as sexual abuse.

Objective: To investigate the picky eating behavior among school-age children and to analyze its association with their health status, providing scientific basis for health promotion of school-age children in China. Methods: A total of 796 students of grade 3 to grade 6 from two primary schools in Hongshan, Wuhan were selected through cluster sampling. Statistical analysis was conducted according to the results of the 3-day food record and questionnaire survey on children and their caregivers. Results: In the current study, 40.58% of the children had picky eating problems, the incidence of picky eating behaviors of migrant children was higher than that of local children(χ2=3.92, P<0.05). Most of the picky eaters(23.87%) tended to reject vegetables. Compared to the others, picky eaters had lower intake of vitamin B 2 [(0.49±0.01)(0.46±0.01)mg] and vitamin C [(57.35±0.76)(54.32±0.90)mg] (t=2.03, 2.57, P<0.05) and had a higher risk of stunting(OR=1.42, P<0.05). Conclusion Picky eating behaviors are common among school-age children, which is significantly associated with stunting. Nutritional education for children (especially migrant children) are urgently needed to improve their dietary structure and promote healthy growth and development.
