Influential factors for anemia in pregnancy based on a nested case-control study in Changsha / 中南大学学报(医学版)

OBJECTIVE@#To explore the prevalence of anemia during pregnancy and the influential factors in changsha city, and to provide scientific evidence for prevention and intervention of anemia during pregnancy. 
@*METHODS@#A cluster sampling of 713 mothers, who delivered baby between January 1, 2013 and December 31, 2013 in the three streets of kaifu district of Changsha, was selected to establish a retrospective cohort. The maternal health information during pregnancy was collected within 15 days after the delivery. The influential factors of anemia during pregnancy were analyzed by the method of retrospective nested case-control study and conditional logistic regression.
@*RESULTS@#The prevalence of anemia during pregnancy in Changsha was 9.96%. The multiple conditional logistic regression results show that high family income (OR=0.632, P=0.020), high education level (OR=0.276, P=0.033), folic acid supplement (OR =0.248, P=0.050), iron supplement (OR=0.272, P<0.001) and eating blood products (OR=0.588, P=0.044) were the beneficial factors for anemia during pregnancy, while multipara (OR=2.917, P=0.003), long duration of menstrual period before pregnancy (OR=1.335, P=0.041), living in new decoration housing (OR=3.690, P=0.045) and tea-drinking (OR=1.365, P=0.094) were the risk factors for anemia during pregnancy. 
@*CONCLUSION@#The prevalence of anemia during pregnancy in Changsha is below the average levels. The occurrence of anemia during pregnancy is closely related to the women's economic level and nutritional status. Women should strengthen maternal nutrition during pregnancy and bedroom environment monitor, drink little strong tea and improve the nutritional status of iron during pregnancy.

Impact of pre-pregnancy body mass index on baby's physical growth and nutritional status / 中南大学学报(医学版)

OBJECTIVE@#To explore the impact of pre-pregnancy body mass index on baby's physical growth and nutritional status.@*METHODS@#A total of 491 pairs of mother-infant were divided into 3 groups according to mother's pre-pregnancy body mass index (BMI): a pre-pregnancy low BMI group (BMI<18.5 kg/m², n=93), a pre-pregnancy normal BMI group (18.5 kg/m² ≤ BMI<24.0 kg/m², n=326), and a pre-pregnancy high BMI group (BMI ≥ 24.0 kg/m², n=72). Analysis of variance of repeated measurement data and the median percentage methods were used to compare the physical growth and nutritional status of babies in different groups.@*RESULTS@#Baby's weight in the high BMI group were higher than that in the normal BMI and the low BMI group (F=3.958, P=0.020). The incidence of malnutrition in the low BMI group showed a tendency to decline along with the months (χ²=5.611, P=0.018), the incidence of overweight and obesity in the high and the normal BMI groups displayed a tendency to decline along with the months (χ²=18.773, 53.248, all P<0.001). Baby in the low BMI group had higher incidence of malnutrition while baby in the high BMI group had higher incidence of overweight and obesity.@*CONCLUSION@#Pregnancy BMI was correlated with the growth of baby. Too high or too low prepregnancy BMI exerts harmful effect on baby's weight and nutritional status. Medical workers should strengthen the education on women's pre-pregnancy to remind them keeping BMI at normal level.

Analysis of the treatment institution selection and its influencing factors in elderly patients with chronic diseases in a community in Changsha / 中华老年医学杂志

Objective To investigate the status of treatment institution selection and its influencing factors in elderly patients with chronic diseases in a community in Changsha.Methods By using systematic sampling,400 elderly patients with chronic diseases from June to August 2012 were included in the investigation by questionnaires.The influencing factors were analyzed by binary logistic regression model or multinomial logistic regression model on the basis of the numbers of response variables.Results In mild conditions in self-consciousness,more than half of the elderly patients with chronic diseases (206 cases,51.5％) preferred community health service centers including private clinics (67 cases,16.8％),municipal hospitals (92 cases,23.0％),third-grade class-A hospitals (35 cases,8.8％).In serious conditions in self-consciousness,patients preferred third-grade class-A hospital (238 cases,59.5％) and municipal hospitals (162 cases,40.5％),no one selected the private clinics or community health service center (x2=443.240,P＜0.001).The analysis of impact factors for the first treatment institution selection in patients with serious conditions in self-consciousness showed that,compared with patients selecting the municipal hospital,the following personnel preferred to choose third-grade class-A hospital:patients in the staff remaining in positions (OR=32.38) and retirees (OR=15.17),patients with monthly income more than 5,000 yuan (OR=134.28),rural cooperative medical patients (OR=661.42),patients with highly trusting in community health service centers (OR=4.23),patients with BP and serum glucose determination at a frequency of once a month to every three months (OR=83.93),patients unknowing the telephone numbers of community health service centers(OR=3.02)and patients living far away from community health service centers (OR=15.70),patients with little information about community health service centers (OR=1.62).The analysis of impact factors for the first treatment institution selection in patients with mild conditions in self-consciousness showed that,compared with patients selecting the private hospitals,the following personnel preferred to choose community health service centers:patients with primary education level (OR=0.15),retired persons (OR=0.14),patients with higher health attention (OR=0.26),while persons with less health attention (OR-10.65) and patients living far away from community health service center (OR =5.22) were more willing to choose the private hospitals.Conclusions Patient selection for treatment agencies is affected mainly by the perceived severity,in addition,age,education level,employment status,income,health insurance type,trust and understanding on community health services centers,and the emphasis on health and the distance from community health services centers.
