Objective To understand the status on care and nutrition of children living in the rural areas (so called 'left-behind' children) while their parents were seeking for jobs in the urban areas. Methods Cross-sectional study was employed in this investigation.The group of‘left-behind' children (n=774) and the comparison group (n=774) were identified.The ascertainment methods mainly included questionnaire,anthropometries measurements,food-frequency,and laboratory examination.Results be poorly attended (X2=6.671,P=0.036;X2=15.053,P=0.001 ).Mothers who chose to work outside of their households would tend to choose bottle-feeding or decrease the duration of breastfeeding for their infants (X2=5.051,P=0.031;t=-7.201,P=0.001).The intake of milk and bean products in children were obviously lower than that seen in the control group (t=-2.150,P=0.032 ;t=-2.054,significant difference when comparing with the control group (X2=4.560,P=0.033 ).Conclusion communities,parents and extended families would facilitate more attention and effective intervention programs to improve the situation.

Objective To understand the schistosomiasis control knowledge,attitude,and practice(KAP),and influenc-ing factors of behaviors among residents in Jiangsu Province,so as to provide the evidence for making effective health education and health promotion models. Methods The probability proportionate to size sampling(PPS)and multi-stage sampling meth-ods were adopted to sample the research objects. A questionnaire survey of schistosomiasis control KAP was conducted in the res-idents of 16 to 69 years old in schistosomiasis endemic areas of Jiangsu Province,and the results were statistically analyzed. Re-sults The total awareness rate of the participants was 95.98%for schistosomiasis control knowledge. The correct rates of atti-tude and practice were 89.06%and 77.43%,respectively. The awareness/correct rates of knowledge,attitude and practice re-duced in turns significantly(χ2=1282.96,P<0.01). The knowledge awareness rate of fishermen and boatmen was 90.98%, but their attitude correct rate was only 53.81%(χ2=120.52,P<0.01). The unconditional logistic regression analysis showed that with the education level increasing,their practice correct rate rose,and the participants with the college degree or above had a higher correct rate compared to illeterate ones(OR=6.411,95%CI:4.896-8.395). The practice correct rate of the fisher-men and boatmen was only 5.1%of the rate of the farmers(OR=0.051,95%CI:0.029-0.091). Conclusions The total aware-ness rate of basic knowledge of schistosomiasis prevention and control in the residents of Jiangsu Province has reached the re-quirements in the"National Schistosomiasis Control Long-term Planning Outline(2004-2015)",but the correct rate of behav-iors is low. The education level,occupation and residential areas affect the health behaviors of schistosomiasis prevention and control. Therefore,it is necessary to carry out targeted health promotion activities to promote the formation of healthy lifestyle and behaviors.
