ABSTRACT
Objective To find out the present situation of complementary feeding, breast-feeding and children nutrition, and further explore the relationship between them. Methods Random sampling was adopted and 7302pairs of mothers and their children under 36 months were investigated by means of questionnaires. Results Breastfeeding rate was 96.8% ,but exclusive breast-feeding rate was only 37.6% . Breast-feeding rate over 12 months was 34.7% ,breast-feeding rate over 24 months was only 15.8%. Timely sucking rate was 8.4％ ,19.2% of children had too early complementary feeding, 26.8% had too late,and 43. 1% had appropriate feeding . To the children over 6months, the feeding rates of meat and eggs per week were 36. 3% and 49. 3 % , respectively. The stunting-rate was 24.0％, underweight-rate 22. 1 ％ ,and wasting-rate 8. 9 ％. The incidence rate of iron deficiency anemia (IDA) was 23.3 %. Multivariable analysis showed that growth of children was associated with diet diversity,intake frequency of eggs and meat, too early complementary feeding,prolonged breast-feeding and diarrhea, etc. Conclusion In rural areas of western China ,breast-feeding has been fundamentally popularized ,however ,the unfit complementary feeding and malnutrition of children under 36 months are common and serious ,important complementary feeding recommendations and good hygiene condition are strongly needed.
ABSTRACT
Objective To analyze and evaluate the impact of adolescents' sexual and reproductive health education on students' sexual knowledge,attitude and behavior.Methods A short-term intervention was conducted among high school students in two schools in Xixiang county,Shaanxi Province.The intervention was carried out in the forms of manual,video,discussion,consultation,and so on .The contents of intervention consisted of the knowledge about adolescent physiology,care,conception,STD/HIV, and so on. Results The results showed that students' knowledge increased significantly(11.92±4.61 before intervention vs 19.81±4.8 after intervention,P=0.000).The sexual attitude and behavior changed insignificantly,especially the change of behavior.Conclusion The intervention is significantly effective in increasing knowledge,but less effective in the change of attitude and almost ineffective in the behavior change.
ABSTRACT
Objective: To find out the current situation of the reproductive health about countrywomen in west of China,and explore the factor of the reproductive health under social medicine theory framework.Methods: Summarize literature about women reproductive which have been done recently,and do 608 samples survey in Xi'an of Shaanxi,which is about the current situations of social economic,reproductive health,gynecological diseases and mental health.Results: The research clarified the primary connotation about the reproductive health of countrywomen,and identified the current situation of countrywomen reproductive health in Shaanxi province of China.Conclusion: The situation of countrywomen reproductive health is far away from the demand of strategic target of "Everyone enjoys the reproductive care since 2015",and the countrywomen are on the hip in birth control,bearing culture,acquirement of health knowledge and primary diathesis.
ABSTRACT
Objective To evaluate relationship between p53 codon72 polymorphism and cervical cancer(CC) by using meta-analysis. Methods Studies from 1998 to 2004 were retrieved through Medline, Elsevier, EBMR, Ovid, CNKI and VIP databases without language limitation. The unpublished data of our study was also included. The inclusion criteria of studies were: ① case-control studies associated with p53 codon72 genotype/allele frequencies and CC. ② CC as the outcome of interest. ③ the risk for CC had odds ratio or enough information to calculate it. RevMan4.2 software was applied to process data. Results All studies were analyzed as subgroups according to pathologic histology and race/region. The outcome of CIN of Asia and European population subgroups showed no statistically difference with the control groups. However, in ICC subgroups the frequencies of Arg/Arg genotype were significantly higher than that in the control group(Z=2.43, P=0.01, OR=1.28; Z=2.44, (P=0.01), OR=1.45). Conclusion This study suggests that polymorphism at codon72 of p53 gene is not associated with an increased susceptibility to CIN. However, a slightly increased risk was observed for ICC of Asian and European population subgroups. A possible susceptibility role of p53 codon72 polymorphism at a late carcinogenetic stage of cervical cancer cannot be ruled out.
