Objective To analyze the descending trend of maternal mortality ratio (MMR) and its related influencing factors in order to improve the descending speed of MMR. Methods The influencial factor analysis and u test were made on data collected from 232 rural counties of eight provinces in China. Results MMR had shown remarkable reduction from 1995 to 2000, a drop by 51.33%. However, there was still a gap if compared with the ratio of the whole country. Major causes influencing the descending speed of MMR include the high speed of economic development, more expenditure of health, quality of maternal service, such as the ratio of hospital delivery, cleaning delivery, prenatal and postnatal health care. Conclusion In order to accelerate the descending speed of MMR, attempts to increase the improvement speed of maternal health care, quality of maternal service and more expenditure of health should be made.

Objective To investigate the status of breastfeeding rate at discharging hospital and analyze influence of obstetrical service quality on breastfeeding rate, in order to improve the quality of obstetrical service and increase the breastfeeding rate. Methods A total number of 1 123 mothers who have 6~12 months babies were investigated through questionnaire including obstetrical service accepted, situation of breastfeeding rate at discharging hospital, mother's breastfeeding knowledge and behaviors with across-sectional method from August to October in 2000. Seven cities were chosen as the research site including Beijing, Changchun, Huhehaote, Xi'an, Luoyang, Kunming and Xiamen. The data were analyzed with SPSS/PC 10.0 statistical software. Results The exclusive breastfeeding rate was 52%, the full breastfeeding rate was 73% at discharging hospital. The influencing factors of breastfeeding rate at discharging hospital include mother's age, medical expenditure type, caesarean section, breastfeeding on demand, neonatal status, having milk bottle, feeding milk-powder and sweeten water in obstetrical wards, mother's breastfeeding knowledge and behavior, et al. Conclusions Breastfeeding rate at discharging hospital was low and it was related with quality of obstetrical service. So it is important to improve the quality of obstetrical service and health education on breastfeeding, in order to enhance the breastfeeding rate.

Objective To analyse both micro level and macro level factors influencing maternal mortality in order to set the priority to lowering maternal mortality. Method The results of an analysis of maternal mortality were reported, based on a conceptual model that combines micro level and macro level variables taken from demographic, sociological and epidemiological research. Multi level analysis techniques were used to analyse the 1997 linked county level maternal death data and related county level social demographic and health resources data in 114 counties of 5 remote and poverty stricken provinces. Results The maternal mortality rate in research areas was as high as 159.3/100 000. The main factors influencing maternal mortality were institutional delivery rate, population density, percentage of minority population, and percentage of village without village doctor. Conclusion To advocate institutional delivery rate, to pay greater attention to minority and low population density area, and to standardised village doctors' responsibility are recommended strategies to lowering maternal mortality in remote and poverty stricken areas of China.

Objective To understand the trends of institutional delivery in recent 30 years in China and find out the main social and demographic factors. Methods Two-staged PPS method was employed for sampling; Uniform questionnaire was drafted and direct interview was adopted to collect the information. Results The institutional delivery rate was increasing rapidly with time, especially from 1990's, which had climbed to 82% in the last three years, but it was still unsatisfactory in the central and western areas. Meanwhile, most women who delivered outside the hospital were assisted only by birth attendants/village doctors or family members/friends in labor. Factor analysis showed that the women s education and occupation and their husbands, the gap of education between the couples, and the antenatal care could significantly affect their choice for where to deliver. Conclusions Great improvement had been achieved in the last several decades, and both individual characteristics, community and health facility could have influences on the women s decision on where to give birth.

As to evaluating the medical compliance of patients with chronic hepatitis B (CHB) and the influence factors, information of 163 patients with CHB treated with lamivudine were collected by using the self-designed questionnaire, and the medical compliance and influencing factors of the patients were acquired by the research followed, and the prognosis and allocation were also observed. The results showed the medical compliance in 77.3% of patients with CHB was good, and in 22.7% patients was poor. After following-up for 2 years, the negative rates of HBV DNA and HBeAg shown in patients with good medical compliance were 78.6% and 46.0%, respectively,showing a significantly higher rate than in those with poor medical compliance, which having the rate of 37.8% and 21.6%, respectively (P<0.01). We suggested that there should be a correlation between the medical compliance of patients with CHB and the prognosis.

OBJECTIVE: To build information repository of the carrying rate of neonatal deafness gene in Shijiazhuang. METHOD: Blood samples were collected from the heel in 3-days neonates. Mutations of the deafness related genes were detected by the method of fluorescent PCR. Neonates received the detection of 6 mutation sites from 3 genes, including GJB2 (235delC, 299-300delAT), SLC26A4 (IVS7-2A> G, 2168A> G), mitochondrial DNA12S rRNA(1494C>T,1555A>G). RESULT: There were 384 neonates who carried mutations among 421 subjects and the carrying rate was 4.08%, 158 (1.68%) newborns carried heterozygous mutations and 1 (0.01%) case carried homogeneous mutation of GJB2 (235 delC), 55 (0.58%) neonates carried heterozygous mutations of GJB2 (299-300delAT); 133 (1.41%) neonates carried heterozygous mutations and 1 (0.01%) homogeneous of SLC26A4(IVS7-2A>G),19 (0.20%) newborns carried heterozygous mutations of SLC26A4 (2168A>G). The numbers of neonates who carried homogeneous and heterogeneous mutation of mitochondrial 12S rRNA gene were 14 and 3 with carring rates of 0.15% and 0.03%. Two newborns were found to carry more than one mutation. One carried 235delC, IVS7-2A>G and 1555A>G and another carried 235delC and IVS7-2A>G. CONCLUSION The main mutational patterns were 235delC from GJB2 gene and IVS7-2A>G from SLC26A4 gene in Shijiazhuang newborns. The carrying rate information repository of neonatal deafness gene has been built preliminarily.

OBJECTIVETo investigate the incidence and risk factors for hypertension among taxi drivers working different shifts.

METHODSUsing the cluster sampling method, 415 day-shift and 304 night-shift taxi drivers in Jinan, China were selected and investigated. The influencing factors for hypertension were analyzed.

RESULTSThe incidence of hypertension in all taxi drivers was 33.2%. The incidence of hypertension in night-shift drivers was significantly higher than that in day-shift drivers (37.8% vs 29.9%, P<0.05). According to multivariate analysis, the incidence of hypertension in day-shift drivers was closely related to body mass index (BMI), working years, working hours, sleep duration, rest days, diet quality, water intake, and smoking, while the incidence of hypertension in night-shift drivers was closely related to BMI, working years, working hours, part-time job, sleep duration, rest days, and drinking.

CONCLUSIONBMI, working years, and working hours are the common risk factors for hypertension in day-shift and night-shift drivers. Sleep duration and rest days are the common protective factors. The risk factors for hypertension in taxi drivers vary with different shifts.
