ABSTRACT
Objective To explore risk factors of unintentional injuries among internal-migrant children. Methods A 1 ∶〗1 matched case-control study was conducted between 332 internal-migrant children with unintentional injuries, based on the principle that same class, same gender and age was no more than two years old. The survey was based on the unified questionnaire. Epi Data 3.1 was used to establish database and SPSS 23.0 was used for univariate analysis and multi-conditional Logistic regression analysis. Results Multi-conditional Logistic regression analysis model indicated that caregiver put pressure on children before exam and the adjusted odd ratio (OR) was 2.086 and 95% confidence interval (CI) was 1.263-3.444, caregiver’s character was extravert type (OR=2.074, 95% CI:1.275-3.372) or middle type (OR=1.796, 95% CI: 1.158-2.784), caregiver’s educational background was illiteracy (OR=1.867, 95% CI: 1.280-2.722) or primary school (OR=2.458, 95% CI: 1.169-5.168), the neurotic behaviors of children (OR=1.466, 95% CI: 1.012-2.124) were risk factors of unintentional injuries among internal-migrant children. Conclusions The characteristics related to internal-migrant children’s caregiver and children’s neurotic behaviors are associated with the occurrence of unintentional injuries. Immediate and effective measures should be taken to ease the high injury prevalence and prevent the unintentional injuries among internal-migrant children.
ABSTRACT
<p><b>OBJECTIVE</b>To determine the incidence of work-related acute pesticide poisoning among farmers in Jiangsu Province and to identify the risk factors.</p><p><b>METHODS</b>Multi-stage stratified sampling and cluster sampling methods were used to randomly select 1490 farmers from the south (Z village), centre (Y village) and north (X village) of Jiangsu Province. The database was established by EpiData 3.1. SPSS 17.0 and SAS 9.13 were used to do chi-square test, trend chi-square test, single factor and multi-factor logistic regression analysis.</p><p><b>RESULTS</b>Among 1490 farmers, 121 people had work-related acute pesticide poisoning in the past year. The incidence rate in Jiangsu Province was 8.1%. 118 farmers (97.5%) were mild pesticide poisoning.3 farmers (2.5%) were moderate pesticide poisoning. The incidence rate of Work-related acute pesticide poisoning in X village of North Jiangsu Province (13.5%, 68/505) is obviously higher than that in Y village of Central Jiangsu Province (4.8%, 19/399) and Z village of South Jiangsu Province (5.8%, 34/586), and the difference is statistically significant (χ(2) = 29.60, P < 0.01). The incidence rate of Work-related acute pesticide poisoning in female (10.4%, 58/557) is obviously higher than that in male (6.8%, 63/933), and the difference is statistically significant (χ(2) = 6.26, P < 0.05). There are lack of safety guidance, unsafety application methods (without alternate row spraying, without backward application, without down-wind application) and risk behaviors in the spraying (without read labels, preparing pesticides without gloves, wiping sweat with hand (s), equipment leakage, body pollution by pesticide, working when feeling sick, without bath after work). If farmers have risk behaviors above, the incidence rate of Work-related acute pesticide poisoning will be obviously higher than farmers who receive safety guidance and have no such dangerous behaviors, and all the differences are statistically significant (P < 0.05). The group of 24 ∼ 34 years old has the highest risk of work-related acute pesticide poisoning (OR = 7.15).</p><p><b>CONCLUSION</b>The incidence rate of work-related acute pesticide poisoning among farmers in Jiangsu Province was higher. Effective measures are needed to prevent and reduce the occurrence of work-related acute pesticide poisoning. We can teach the farmers who spray pesticides about safety guidance, safety application methods and avoiding risky behaviors.</p>

<p><b>OBJECTIVE</b>To investigate the incidence of needlestick and sharps injuries among the medical staff in an upper first-class hospital and its risk factors and to provide a basis for the infection control department of hospital and health administration department to establish the policies for safe injection.</p><p><b>METHODS</b>A questionnaire survey was conducted in 800 healthcare professionals in an upper first-class hospital in Nanjing, China to investigate the incidence of needlestick and sharps injuries in the past year. A total of 641 persons completed the questionnaire, including 239 doctors, 348 nurses, and 54 other healthcare workers. The obtained data were subjected to chi-square test and logistic analysis.</p><p><b>RESULTS</b>Needlestick and sharps injuries occurred in 373 of 641 healthcare professionals, with an incidence rate of 58.19%. There were significant differences in the incidence of needlestick and sharps injuries among the medical staff of different types or in different departments (P < 0.01). The syringe needles, glass, scalp infusion needles, and suture needles were the major medical apparatus that caused needlestick and sharps injuries; the incidence rate of injury caused by suture needles in doctors (48.21%) was significantly higher than that in nurses (6.72%) (P < 0.01), and the incidence rates of injuries caused by syringe needles, scalp infusion needles, and glass in nurses (71.15%, 59.68%, and 49.04%) were significantly higher than those in doctors (46.43%, 6.25%, and 16.96%) (P < 0.01); compared with nurses, the doctors had higher incidence rates of injuries due to body fluid or tissue sample collection, wound flushing, suture, and cutting (P < 0.05); compared with doctors, the nurses had higher incidence rates of injuries due to injection, intravenous infusion, heparin cap sealing, intravenous infusion line connection, and venous or arterial blood collection (P < 0.05).</p><p><b>CONCLUSION</b>Needlestick and sharps injuries are common in medical staff. The results of the study on risk factors provide a basis for the infection control department of hospital and health administration department to establish the policies for safe injection.</p>

This research aimed to explore the application of autoregressive integrated moving average (ARIMA) model of time series analysis in predicting road traffic injury (RTI) in China and to provide scientific evidence for the prevention and control of RTI.Database was created based on the data collected from monitoring sites in China from 1951 to 2011.The ARIMA model was made.Then it was used to predict RTI in 2012.The ARIMA model of the RTI cases was Yt=eYt-1+0.456▽Yt-1+et (et stands for random error).The residual error with 16 lags was white noise and the Ljung-Box test statistic for the model was no statistical significance.The model fitted the data well.True value of RTI cases in 2011 was within 95％ CI of predicted values obtained from present model.The model was used to predict value of RTI cases in 2012,and the predictor (95％CI) was 207 838 (107 579-401 536).The ARIMA model could fit the trend of RTI in China.
ABSTRACT
Objective To explore the risk factors on cases regarding work-related acute pesticide poisoning among farmers of Jiangsu province.Methods A population-based,1 ∶ 2 matched case-control study was carried out,with 121 patients as case-group paired by 242 persons with same gender,district and age less then difference of 3 years,as controls.Cases were the ones who had suffered from work-related acute pesticide poisoning.A unified questionnaire was used.Data base was established by EpiData 3.1,and SPSS 16.0 was used for both data single factor and multi-conditional logistics regression analysis.Results Results from the single factor logistic regression analysis showed that the related risk factors were:lack of safety guidance,lack of readable labels befores praying pesticides,no regression during application,using hand to wipe sweat,using leaking knapsack,body contaminated during application and continuing to work when feeling ill after the contact of pesticides.Results from multi-conditional logistic regression analysis indicated that the lack of safety guidance (OR=2.25,95％ CI:1.35-3.74),no readable labels befores praying pesticides (OR=1.95,95％ CI:1.19-3.18),wiping the sweat by hand during application (OR=1.97,95％CI:1.20-3.24)and using leaking knapsack during application (OR=1.82,95％ CI:1.10-3.01) were risk factors for the occurrence of work-related acute pesticide poisoning.Conclusion The lack of safety guidance,no readable labels befores praying pesticides,wiping the sweat by hand or using leaking knapsack during application were correlated to the occurrence of work-related acute pesticide poisoning.
