ABSTRACT

Objective: To understand the influence of chronic diseases on the risk of impaired activities of daily living (ADL) of the elderly. Methods: Baseline data of 10 501 elderly individuals recruited by the Chinese Longitudinal Healthy Longevity Survey in 2002 were used, and follow up for this population was conducted until 2014. Cox Proportional Hazard Model was used to estimate the hazards ratios (HR) for the associations between five kinds of chronic diseases, the number of chronic diseases and the risk of ADL impairment in different age groups of the elderly. Results: Hypertension increased the risk of ADL impairment in the elderly of all age groups, which increased the ADL impaired risk by 43% (HR=1.43, 95%CI: 1.14-1.79) in group aged 65-74 years, 21% (HR=1.21, 95%CI: 1.02-1.43) in group aged 75-89 years and 20% (HR=1.20, 95%CI: 1.02-1.43) in group aged 90-105 years, respectively. Diabetes and cerebrovascular disease increased the ADL impaired risk by 102%(HR=2.02, 95%CI: 1.29-3.17), and 79% (HR=1.79, 95%CI: 1.24-2.58) in group aged 65-74 years, respectively. 'Suffering from one chronic disease' increased the ADL impaired risk by 13% (HR=1.13, 95%CI: 1.02-1.25), and suffering from two or more chronic diseases increased the ADL impaired risk by 25% (HR=1.25, 95%CI: 1.13-1.40) in all the age groups. Suffering from two or more chronic diseases increased the ADL impaired risk by 50% (HR=1.50, 95%CI: 1.21-1.87) in group aged 65-74 years and 17% (HR=1.17, 95%CI: 1.01-1.38) in groups aged 75-89 years. Conclusions: Hypertension was one of the most important risk factors for the impaired ADL in the elderly population in all age groups. Hypertension, diabetes, cerebrovascular disease or comorbidity increased the risk of impaired ADL in group aged 65-74 years.

ABSTRACT

Objective@#To explore the spatial distribution of low birth weight (LBW) and the potential environmental risk factors and provide the evidence for the prevention and intervention of LBW.@*Methods@#Data were from a surveillance system for newly born population and adverse pregnancy outcome between 2007 and 2012 in Pingding county, Shanxi province. The data from 313 villages were analyzed. Spatial hierarchical Bayesian model was used to adjust the risk of LBW at village level, Moran’s I and Getis-Ord Gi* were used to analyze the difference in distribution of LBW risk area. Spatial negative binomial model was used to evaluate the association between the risk of LBW and chemical fertilizer application.@*Results@#A total of 18 749 new births were recorded between 2007 and 2012, including 911 LBW cases, the total incidence of LBW was 4.86%. The result of the spatial hierarchical Bayesian model showed that high-risk area of LBW was in the southeast of Pingding and low-risk area was in the middle west of Pingding. The result of Moran’s I showed that there was a clustering pattern of LBW risk, and Getis-Ord Gi* found a high risk (hot spot) area in the south area. Moreover, the findings of association analysis showed that the risk of LBW increased with the increased chemical fertilizer application at village level.@*Conclusions@#There were area specific differences in the risk of LBW, and dose-response relationship between chemical fertilizer application and the risk of LBW. Our findings suggest that maternal exposure to chemical fertilizer during pregnancy might be a potential risk factor for LBW in rural area.

ABSTRACT

Objective: To explore the association between the consumption of chemical fertilizers and the risk of low birth weight (LBW), to provide references for prevention programs on LBW and to improve the birth outcomes. Methods: Stratified multivariate logistic regression method was used in this study involving 153 preterm LBW infants, 179 term LBW infants and 204 normal control infants that were randomly selected from the birth monitoring data between October 2007 and September 2012 in Pingding county, Shanxi province. Associations between the risk of LBW and maternal exposure to chemical fertilizers during pregnancy were identified. A normal control group was set up to compare results between preterm and term LBW groups. Results: Totally, 18 749 infants were born between 2007 and 2012, with the total incidence rates of LBW as 48.5‰, preterm LBW as 19.4‰, and term LBW as 29.1‰. Concerning the case control study on preterm LBW, after adjustment for confounding factors, the risk of preterm LBW appeared 2.51 (95%CI: 1.05-5.99) times higher in villages with annual consumption of chemical fertilizer ≥100 tons than those villages that using chemical fertilizer less than 50 tons. No significant statistical associations were found between the amounts of household chemical fertilizer consumption and the risks of preterm LBW. Regarding the case control study on term LBW, after adjustment for confounding factors, in villages with ≥100 tons annual consumption of chemical fertilizers, the risk of term LBW was 4.03 (95%CI: 1.63-9.92) times of the risk in villages where the annal use of chemical fertilizers was less than 50 tons. There was no significant association between household consumption of chemical fertilizers and the risk of term LBW. Conclusions: Maternal exposure to chemical fertilizers during pregnancy was associated with the risk of LBW. Our findings suggested that the amount of chemical fertilizer consumption in rural areas seemed also associated with the risks of other adverse pregnancy outcomes. Women should avoid the chance of exposure to chemical fertilizers during pregnancy and the consumption of chemical fertilizers should be carefully managed.

ABSTRACT

Objective To compare the effect and safety of digital flexible ureteroscopic lithotripsy and per-cutaneous nephrolithotomy for renal calculi. Methods Clinic data of 105 cases with kidney stones were analyzed retrospectively, including 53 cases with digital flexible ureteroscopic lithotripsy (group A) and 52 with minimally invasive percutaneous nephrolithotomy (group B). The operative time, intraoperative blood loss, stone-free rate, complications, average hospitalization time were compared. Results There were no significant differences in age, gender, stone size, stone surface area, average operative time, stone-free rate and complications between two groups. Significant differences were found between group A and group B in terms of intraoperative blood loss and average hospitalization time. Conclusions Digital flexible ureteroscopic lithotripsy has similar effect as minimally invasive percutaneous nephrolithotomy for the treatment of kidney stones about 20 mm in terms of average operative time, stone-free rate, and complications, but excels minimally invasive percutaneous nephrolithotomy in intraopera-tive blood loss and average hospitalization time. Digital flexible ureteroscopic lithotripsy can be the first choice for the treatment of kidney stones about 20 mm.

ABSTRACT

Objective To understand the current status of prenatal health care(PHC) and its related factors for floating women of childbearing age,and to provide evidence for improving the quality of PHC at childbearing age.Methods With data from the reproductive health survey on floating population in five cities,Beijing,Nanjing,Xiamen,Shenzhen and Chongqing,in 2005,the distributions of PHC among floating women were described.Multivariate logistic regression was performed to investigate the factors related to the utilization of PHC.Results In 5 399 cases of valid questionnaires,4 037 floating women who had the history of pregnant,cases who had or did not have PHC services would account for 75.3% (3 041/4 037) and 24.7% (996/4 037),respectively.The initial time of using the PHC service was significantly associated with the level of their education (P< 0.05) received.Data from the multivariate logistic regression analysis in PHC showed that there were differences between regions (P<0.05).Proportions of women receiving PHC among those under 30 years and 30-39 were 4.09-folds (95% CI:3.11-5.39) and 1.98-folds (95% CI:1.61-2.43),respectively,when compared with that of women over 40-year-old.The proportion of women having received PHC with education levels of senior high school and above or junior high school,were 5.47-folds (95%CI:3.85-7.77) and 2.86-folds (95%CI:2.42-3.39) respectively,compared to that of women with education level of primary school or below.The proportion of married women having PHC was 2.36-folds (95%CI:1.07-5.22) of those unmarried women.The proportions of having PHC of women with one parity and two parities or with family planning certificate were 3.36-fold (95%CI:2.33-4.84) and 1.61-fold (95%CI:1.12-2.30),1.44-folds (95%CI:1.21-1.71) respectively,when compared with those women with three parities or without the certificate.Conclusion Factors as having received higher education,being married,with less parities or having family planning certificate etc.showed protective effects on PHC for floating women of childbearing age.Based on PHC,education should be promoted among the floating women of childbearing age,which would contribute to the prevention and reduction of adverse outcomes related to reproductive health.

ABSTRACT

Objective To analyze and explore the value of the mutislice spiral CT (MSCT) scanning,its reconstructive technology and MRI scanning for applying to the identifying diagnosis of new and old vertebral compresion fracture.Methods One hundred and sixty-seven cases with the new and old vertebral compresion fracture who have 189 vertebrae in total were examined using the MSCT scanning,their imaging information were postprocessed with 2D and 3D reconstruction at the work station.Thirty-four patients with overall 43 vertebrae were carried out by MRI scanning and their images were compared with those of MSCT.Results They had the highest proportion of vertebrae in L1 with accounting for 27.68% (31/112) and 35.06% (27/77) among the patients with new and old vertebral compresion fracture,respectively.The next was T12,L2 and T11.There were statistically significant differences between new and old cases in such appearance as fracture line clear and sharp(102 and 21),contusion and hemorrhage of spinal cord(15 and 0),parenchyma shadow beside vertebrae(103 and 11),appendant fracture(26 and 5),organ's lacerated wound around vertebral body(30 and 0),discus intervertebrales vacuum(10 and 36),derangement and hardening of vertebral bone trabecularism(29 and 51) (P<0.01).Twenty-six vertebrae with the uneven low T1 WI signal,27 vertebrae with the T2 WI fat-suppresion irregular high signal were demonstrated in MRI scanning among 27 vertebrae of 21 cases with new vertebral compresion fracture.While 16 vertebrae with the T1WI and T2WI signals were the same as those of the normal vertebrae,16 vertebrae were the T2WI fat-suppresion low signal among 13 cases with old vertebral compresion fracture.Conclusions The MSCT plays an important role in identifying diagnosis for the most of the patients with the new and old vertebral compresion fracture, while MRI scanning may reflect the pathophysiological characteristics in diagnosis of the spinal cord and the ligament lesion.Therefore,the MSCT and MRI scanning should be integrated to be used to enhance remarkably the accurate rate of the diagnosis.
