ABSTRACT

BACKGROUND@#There are few multi-city studies on the association between temperature and mortality in basin climates. This study was based on the Sichuan Basin in southwest China to assess the association of basin temperature with non-accidental mortality in the population and with the temperature-related mortality burden.@*METHODS@#Daily mortality data, meteorological and air pollution data were collected for four cities in the Sichuan Basin of southwest China. We used a two-stage time-series analysis to quantify the association between temperature and non-accidental mortality in each city, and a multivariate meta-analysis was performed to obtain the overall cumulative risk. The attributable fractions (AFs) were calculated to access the mortality burden attributable to non-optimal temperature. Additionally, we performed a stratified analyses by gender, age group, education level, and marital status.@*RESULTS@#A total of 751,930 non-accidental deaths were collected in our study. Overall, 10.16% of non-accidental deaths could be attributed to non-optimal temperatures. A majority of temperature-related non-accidental deaths were caused by low temperature, accounting for 9.10% (95% eCI: 5.50%, 12.19%), and heat effects accounted for only 1.06% (95% eCI: 0.76%, 1.33%). The mortality burden attributable to non-optimal temperatures was higher among those under 65 years old, females, those with a low education level, and those with an alternative marriage status.@*CONCLUSIONS@#Our study suggested that a significant association between non-optimal temperature and non-accidental mortality. Those under 65 years old, females, and those with a low educational level or alternative marriage status had the highest attributable burden.

ABSTRACT

Objective To investigate the attributable risk(AR)of Acinetobacter baumannii(AB)infection in criti-cally ill patients.Methods A multicenter retrospective cohort study was conducted among adult patients in inten-sive care unit(ICU).Patients with AB isolated from sterile body fluid and confirmed with AB infection in each cen-ter were selected as the infected group.According to the matching criteria that patients should be from the same pe-riod,in the same ICU,as well as with similar APACHE Ⅱ score(±5 points)and primary diagnosis,patients who did not infect with AB were selected as the non-infected group in a 1:2 ratio.The AR was calculated.Results The in-hospital mortality of patients with AB infection in sterile body fluid was 33.3%,and that of non-infected group was 23.1%,with no statistically significant difference between the two groups(P=0.069).The AR was 10.2%(95%CI:-2.3%-22.8%).There is no statistically significant difference in mortality between non-infected pa-tients and infected patients from whose blood,cerebrospinal fluid and other specimen sources AB were isolated(P>0.05).After infected with AB,critically ill patients with the major diagnosis of pulmonary infection had the high-est AR.There was no statistically significant difference in mortality between patients in the infected and non-infec-ted groups(P>0.05),or between other diagnostic classifications.Conclusion The prognosis of AB infection in critically ill patients is highly overestimated,but active healthcare-associated infection control for AB in the ICU should still be carried out.

ABSTRACT

RESUMEN Introducción : El consumo de tabaco es la principal causa de defunción por enfermedades no transmisibles como las cardiopatías, las neumopatías y el cáncer. Estimar la mortalidad atribuida al consumo de tabaco dependiente de su prevalencia se basa en el conocimiento previo del número de fumadores, exfumadores y no fumadores en la población. Estos datos provienen de las cuatro Encuestas Nacionales de Factores de Riesgo (ENFR). Objetivos : El presente trabajo pretende mostrar la carga de mortalidad por consumo de tabaco en la Provincia de Buenos Aires en los períodos de relevamiento de las cuatro ENFR (2005-2009-2013-2018). Material y métodos : La mortalidad atribuible fue calculada utilizando un método dependiente de la prevalencia, y asumiendo los riesgos asociados al consumo en las 19 causas clasificadas como asociadas al tabaquismo según el estudio Cancer Prevention Study II (CPSII). Las defunciones fueron agrupadas en períodos equivalentes a los relevamientos de cada ENFR. Las fracciones atribuibles del CSPII se aplicaron entonces calculando las defunciones absolutas y atribuibles de mortalidad por causa y sus agrupamientos: tumores, circulatorias y respiratorias. Resultados : Globalmente, para todas las edades de 18 años y más, se pasó de una prevalencia de tabaquismo del 29,5% en 2005 al 23,1% en 2018 (reducción absoluta de 6,4% y porcentual del 21,7%). De las 18 255 muertes producidas por enfermedades cardiovasculares coincidentes con los cuatro relevamientos, 6293 fueron atribuibles al tabaquismo (34,4%), frente al 68% de las muertes por tumores y el 40% de las muertes de causa respiratoria. Conclusión : Se hace necesario fortalecer aún medidas para reducir la exposición al tabaco.


ABSTRACT Background : Tobacco consumption is the leading cause of death from non-communicable diseases, such as heart disease, lung disease and cancer. Estimating prevalence-based mortality attributed to tobacco consumption is based on prior knowledge of the number of smokers, ex-smokers, and non-smokers in the population. These data derive from the four National Surveys of Risk Factors (Encuestas Nacionales de Factores de Riesgo, ENFR). Objectives : This study aims to show the burden of mortality due to tobacco consumption in the Province of Buenos Aires in the assessed periods of the four ENFRs (2005, 2009, 2013, 2018). Methods : Mortality attributable to tobacco consumption was estimated by using a prevalence-based method and assuming the risks associated with smoking in the 19 causes classified as associated with smoking, in accordance with the Cancer Prevention Study II (CPSII). The deaths were grouped into periods equivalent to those relevant to each ENFR. The CSPII attributable fractions were then applied by estimating the absolute deaths and attributable fractions of mortality by cause and groupings: tumours, circulatory diseases and respiratory diseases. Results : Overall, in persons aged 18 years or older, there was a decrease in smoking prevalence from 29.5% in 2005 to 23.1% in 2018 (an absolute reduction of 6.4% and a percentage reduction of 21.7%). A total of 6293 out of 18 255 deaths from cardiovascular diseases in the four surveys were attributed to smoking, that is, 34.4%, compared to 68% of deaths from tumours and 40.0% of deaths from respiratory diseases. Conclusion : It is necessary to further strengthen measures to reduce exposure to tobacco.

ABSTRACT

Background Welders in automobile manufacturers are prone to hand/wrist musculoskeletal disorders (MSDs), which seriously affect workers' physical and mental health. Objective To investigate the factors influencing hand/wrist MSDs of welders in an automobile factory and the population attributable risk percentage (PARP). Methods Five branches of an automobile factory were selected by convenient sampling method, and all qualified welders in the selected branches were enrolled as research participants. The Chinese Musculoskeletal Disorders Questionnaire was used to collect information such as general characteristics of welders, presentation of MSDs in the wrists and hands, and selected ergonomic factors. Log-binomial model in the SAS program was used to calculate the prevalence ratio (PR) of each influencing factor and PARP. Results The prevalence rate of MSDs in the hands/wrists of welders in the automobile factory was 44.1% (345/782). The results of multiple analysis showed that female (PR=1.25, 95%CI: 1.10-1.44), being very tired after work (versus not tired, PR=2.22, 95%CI: 1.16-4.25), twisting wrists (PR=1.44, 95%CI: 1.19-1.74), insufficient operating space (PR=1.22, 95%CI: 1.07-1.40), and holding or pinching objects by hands (PR=1.58, 95%CI: 1.18-2.12) increased the risk of reporting hand/wrist MSDs symptoms. The PARP of major occupational risk factors was: holding or pinching objects by hands, 32.46%; twisting wrists, 21.50%; being very tired after work, 15.28%; and insufficient operating space, 8.18%. Conclusion The prevalence of MSDs symptoms in hands/wrists of welders in this automobile factory is high. Gender, holding or pinching objects by hands, twisting wrists, being very tired after work, and insufficient operating space are the factors affecting hand/wrist MSDs, among which holding or pinching objects by hands and twisting wrists are the priority intervention factors.

ABSTRACT

Objective:To evaluate the influence of depression and anxiety on sleep quality, and to provide a basis for preventing sleep disorders in community-dwelling older adults.Methods:Cluster sampling was used.A self-designed questionnaire, the Pittsburgh Sleep Quality Index(PSQI), the Patient Health Questionnaire-9(PHQ-9), and the Generalized Anxiety Disorder Questionnaire-7(GAD-7)were used for the survey.The sleep quality and the influence of depression and anxiety on sleep quality of 955 community-dwelling older adults aged 60 and above were investigated.Results:The detection rate of sleep disorders, depression and anxiety were 24.5%, 19.1% and 14.3%, respectively.There was a positive correlation between sleep quality scores(including the total score and the scores of each dimension)and the anxiety and depression scores( rs: 0.115-0.558, P<0.01 for all). After adjusting for possible confounding effects of gender, age, food intake or tea drinking before bed, Logistic regression analysis showed that the presence of depression( OR=3.555, 95% CI: 2.235-5.653, P<0.05)and anxiety( OR=1.812, 95% CI: 1.070-3.070, P<0.05)were significantly related to sleep disorders in the elderly.The multivariate adjusted population attributable risk of depression and anxiety for sleep disorders in the elderly was 32.56% and 16.09%, respectively.The presence of depression and anxiety were associated with 38.87% of the population attributable risk for sleep disorders. Conclusions:Depression and anxiety are important risk factors for sleep disorders in the elderly.Strengthening the identification and intervention of depression and anxiety is beneficial to improve the sleep quality of elderly living in the community.

ABSTRACT

Objective: To investigate the influencing factors and population attributable risk percent (PAR%) of low back pain in automobile assemblers. Methods: A total of 634 assemblers from 11 automobile manufacturers in Shiyan City, Hubei Province were chosen as research subjects using judgment sampling method. The prevalence of low back pain in the past one year was investigated using Musculoskeletal Disorders Questionnaire. PAR% was used to analyze the contribution of influencing factors to low back pain. Results: The annual prevalence of low back pain was 68.8%. The results of multivariate logistics regression showed that length of service>15 years, high school or secondary college education or above, standing most of the time, sitting most of the time, the proportion of cumulative time of poor posture in work shift time ≥1/8, and bending for insufficient height of working space were the risk factors for low back pain (all P<0.05). The PAR% of the proportion of cumulative time of poor posture in work shift time ≥1/8 was 43.0%, 37.8% for standing most of the time, and 12.8% for bending for insufficient height of working space. Conclusion: The annual prevalence of low back pain was higher in automobile assemblers. The influencing factors included individual factors and occupational factors. The proportion of cumulative time of poor posture in work shift time ≥1/8, standing most of the time and bending for insufficient height of working space should be taken as the priority intervention factors to reduce the prevalence of low back pain among assemblers in this enterprise.

ABSTRACT

Abstract INTRODUCTION: To better understand trends in the main cause of death in Brazil, we sought to analyze the burden of cardiovascular risk factors (RF) and cardiovascular diseases (CVD) attributable to specific RFs in Brazil from 1990 to 2019, using the estimates from the GBD 2019 study. METHODS: To estimate RF exposure, the Summary Exposure Value (SEV) was used, whereas for disease burden attributed to RF, mortality and disability-adjusted life-years (DALY) due to CVD were used. For comparisons over time and between states, we compared age-standardized rates. The sociodemographic index (SDI) was used as a marker of socioeconomic conditions. RESULTS: In 2019, 83% of CVD mortality in Brazil was attributable to RF. For SEV, there was a reduction in smoking and environmental RF, but an increase in metabolic RF. High systolic blood pressure and dietary risks continue to be the main RF for CVD mortality and DALY. While there was a decline in age-standardized mortality rates attributable to the evaluated RF, there was also a stability or increase in crude mortality rates, with the exception of smoking. It is important to highlight the increase in the risk of death attributable to a high body mass index. Regarding the analysis per state, SEVs and mortality attributable to RF were higher in those states with lower SDIs. CONCLUSIONS: Despite the reduction in CVD mortality and DALY rates attributable to RF, the stability or increase in crude rates attributable to metabolic RFs is worrisome, requiring investments and a renewal of health policies.

ABSTRACT

Históricamente, se ha evidenciado una vulneración de los derechos de la población LGBTIQ desde lo social, lo cultural, lo económico y lo laboral; sin embargo, poco a poco, ha empezado a participar política para la consecución de sus derechos y el recono-cimiento de estos. Objetivo: Identificar políticas públicas y legislaciones que cobijen a la comunidad LGBTIQ en países latinoamericanos como Argentina, Chile, Brasil, Colombia, Ecuador, El Salvador y México. Metodología: Revisión de literatura de tipo descriptiva, con documentos sobre políticas públicas en la población LGBTIQ. Se buscó en bases de datos como ProQuest, SciELO y Google Académico, en idioma español, en su gran mayoría por tratarse de políticas públicas latinoamericanas. Se obtuvieron sesenta documentos que cumplían con los criterios de inclusión y exclusión. Resultados: En países como Argentina, Ecuador y Colombia se reconoce la unión de hecho entre personas del mismo sexo, y en el caso de Argentina se da cabida al matrimonio. Con respecto a políticas contra la discriminación, están establecidas en países como Argentina, Brasil, Colombia y El Salvador; en cuanto a México, se prohíbe el matrimonio entre personas homosexuales. Conclusiones: Existen políticas públicas y los derechos que han adoptado en algunos países latinoamericanos para beneficiar a la comunidad LGBTIQ, para evitar que sigan siendo víctimas de violencia física, psicológica y social. Ello repercute en el gobier-no, el Estado y la organizaciones internacionales, que han creado las políticas públicas en su beneficio


Historically, the LGBTIQ population's social, cultural, economic and labor rights have been violated; however, social movements have gradually led to the political participation of this population for the achievement of their rights and their recognition. Objective: To identify public policies and legislation that cover the LGBTIQ community in Latin American countries such as Argentina, Chile, Brazil, Colombia, Ecuador, El Salvador and Mexico. Methodology: Descriptive literature review, with documents on public policies on the LGBTIQ population; the search was carried out in databases such as ProQuest, SciELO and Google Academic in Spanish language mostly because they deal with Latin American public policies; 60 documents were obtained that met the inclusion and exclusion criteria. Results: In countries such as Argentina, Ecuador and Colombia, de facto unions between persons of the same sex are recognized; in the case of Argentina, marriage is recognized. With respect to policies against discrimina-tion, they are established in countries such as Argentina, Brazil, Colombia and Salvador; as for Mexico, marriage between homosexual persons is prohibited. Conclusions: There are public policies and rights that have been adopted in some Latin American countries to benefit the LGBTIQ community, preventing them from continuing to be victims of physical, psychological and social violence impacting the government, the State and international organizations creating public policies for their benefit

ABSTRACT

BACKGROUND@#Understanding the association between floods and bacillary dysentery (BD) incidence is necessary for us to assess the health risk of extreme weather events. This study aims at exploring the association between floods and daily bacillary dysentery cases in main urban areas of Chongqing between 2005 and 2016 as well as evaluating the attributable risk from floods.@*METHODS@#The association between floods and daily bacillary dysentery cases was evaluated by using distributed lag non-linear model, controlling for meteorological factors, long-term trend, seasonality, and day of week. The fraction and number of bacillary dysentery cases attributable to floods was calculated. Subgroup analyses were conducted to explore the association across age, gender, and occupation.@*RESULTS@#After controlling the impact of temperature, precipitation, relative humidity, long-term trend, and seasonality, a significant lag effect of floods on bacillary dysentery cases was found at 0-day, 3-day, and 4-day lag, and the cumulative relative risk (CRR) over a 7-lag day period was 1.393 (95%CI 1.216-1.596). Male had higher risk than female. People under 5 years old and people aged 15-64 years old had significantly higher risk. Students, workers, and children had significantly higher risk. During the study period, based on 7-lag days, the attributable fraction of bacillary dysentery cases due to floods was 1.10% and the attributable number was 497 persons.@*CONCLUSIONS@#This study confirms that floods can increase the risk of bacillary dysentery incidence in main urban areas of Chongqing within an accurate time scale, the risk of bacillary dysentery caused by floods is still serious. The key population includes male, people under 5 years old, students, workers, and children. Considering the lag effect of floods on bacillary dysentery, the government and public health emergency departments should advance to the emergency health response in order to minimize the potential risk of floods on public.

ABSTRACT

Abstract INTRODUCTION: Although congenital syphilis is preventable, its incidence has increased in Brazil. METHODS: In this ecological study, a Bayesian spatio-temporal model was used to estimate the attributable fraction of congenital syphilis cases due to the lack of prenatal care recorded between 2010 and 2015 in the state of São Paulo, Southeast Brazil. RESULTS: For the year 2016, it was estimated that between 79.4% and 95.3% of the congenital syphilis cases among women who did not have prenatal care could have been prevented. CONCLUSIONS: A significant proportion of congenital syphilis cases can be prevented if prenatal care coverage is expanded.

ABSTRACT

RESUMO: Objetivo: Estimar a fração de câncer de cabeça e pescoço (CCP) atribuível ao tabaco e ao álcool em cidades das regiões Centro-Oeste, Sudeste E Sul do Brasil. Métodos: Estudo caso-controle com 1.594 casos de CCP e 1.292 controles hospitalares. A associação de CCP com tabaco e álcool foi estimada pela odds ratio e intervalos de confiança de 95% via regressão logística não condicional, ajustada por idade, sexo, escolaridade, consumo de frutas e legumes, consumo de bebidas alcoólicas (para examinar o efeito do tabaco) e tabagismo (para examinar o efeito do álcool). As proporções de CCP atribuíveis ao tabaco e ao álcool foram estimadas pelo cálculo da fração atribuível (FA). Foram realizadas estimativas separadas para Goiânia (Centro-Oeste), Rio de Janeiro e São Paulo (Sudeste) e Pelotas e Porto Alegre (Sul). Resultados: A fração de CCP atribuível ao tabagismo foi discretamente mais elevada em Goiânia (FA = 90%) em comparação às cidades do Sudeste (FA = 87%) e do Sul (FA = 86%). A fração de CCP atribuível ao consumo de bebidas alcoólicas apresentou resultados similares e mais altos nas cidades do Sudeste (FA = 78%) e Sul (FA = 77%) em comparação a Goiânia (FA = 62%). Conclusão: As frações de CCP atribuíveis ao tabagismo foram mais expressivas do que para o consumo de álcool. Embora com discretas distinções entre si, as FA para tabaco e álcool observadas nas cidades das três regiões brasileiras foram semelhantes às obtidas em estudos em outras regiões da América Latina, porém, mais altas que em outras partes do mundo.


ABSTRACT: Objectives: To estimate the fraction of head and neck cancer (HNC) attributable to tobacco and alcohol in cities in the Midwest, Southeast and South regions of Brazil. Methods: Case-control study including 1,594 cases of HNC and 1,292 hospital controls. The association of HNC with tobacco and alcohol was estimated by the odds ratio and respective 95% confidence intervals through non-conditional logistic regression, adjusted for age, sex, schooling, consumption of fruits and vegetables, alcohol drinking (to examine the tobacco effect), and tobacco smoking (to examine the alcohol effect). The proportions of HNC attributable to tobacco and alcohol were estimated through the attributable fraction (AF) calculation. Separate estimates were made for Goiânia (Midwest), Rio de Janeiro and São Paulo (Southeast) and Pelotas and Porto Alegre (South). Results: The HNC fraction attributable to smoking was slightly higher in Goiânia (AF = 90%) than in cities in the Southeast (AF = 87%) and South (AF = 86%). The HNC fraction attributable to the consumption of alcoholic beverages presented similar and higher results in the cities of Southeast (AF = 78%) and South (AF = 77%) than in Goiânia (AF = 62%). Conclusion: The HNC fractions attributable to smoking were more expressive than for alcohol consumption. Although with discrete distinctions between them, the AFs to tobacco smoking and alcohol consumption in HNC observed in the cities of these three Brazilian regions were similar to those obtained in Latin America studies, but they were higher than in other parts in the world.

ABSTRACT

Objective To estimate the lifetime attributable risk (LAR) of lung cancer,stomach cancer,liver cancer,thyroid cancer,breast cancer and leukemia for 1-,5-and 10-year old children undergoing chest CT scan.Methods Chest CT images of children was retrieved from the picture archiving and communication system (PACS) and the average CT number and area of the region of interest (ROI) were read on the CT work station.Water equivalent diameter were calculated according to the method recommended by the American Association of Physicists in Medicine (AAPM).Furthermore,the size-specific dose estimation (SSDE) was made based on the water equivalent diameter and the volume computed tomography dose index(CTDIvol).Based on the method recommended by Caro Franck,the SSDE then was converted into average organ doses to lung,stomach,liver,thyroid,breast and blood for children at different ages and of different sex undergoing chest CT scan.On the basis of average organ dose,the cancer risk prediction model from the National Academy of Science's Biological Effects of Ionizing Radiation-Ⅶ (BEIR-Ⅶ) was used to predict the LAR for different cancers mentioned above.For lung cancer,gastric cancer,liver cancer and leukemia,the calculating sequence was from average organ dose to excess relative risk (ERR) to LAR,whereas for the thyroid cancer and breast cancer,the sequence was from ERR to average organ dose to LAR.Results The average organ dose to lung,stomach,liver,thyroid,breast and blood for children at different age and of different sex undergoing chest CT scan was obtained.The age had a statistically significant impact on the SSDE (t =24.28,P < 0.05),but sex has not (P > 0.05).LAR for lung cancer,gastric cancer,liver cancer,thyroid cancer,breast cancer and leukemia for 1-,5-and 10-year old children undergoing chest CT scan was obtained,among whom the LAR for thyroid cancer and breast cancer was relatively high.The LAR for women breast cancer was 10.9 per 100 000 persons for 1 year old children,30.8 per 100 000 persons for 5 years old and 34.5 per 100 000 persons for 10 years old.Conclusions With introduction of new technologies,the radiation dose due to chest CT scan is on the decline.But the induced radiation dose is still significant compared with general diagnostic radiography.The risk of cancer still deserves more attention and should be taken into consideration in the justification of diagnostic radiology.

ABSTRACT

PURPOSE: Exposure to indoor radon is associated with lung cancer. This study aimed to estimate the number of lung cancer deaths attributable to indoor radon exposure, its burden of disease, and the effects of radon mitigation in Korea in 2010. MATERIALS AND METHODS: Lung cancer deaths due to indoor radon exposure were estimated using exposure-response relations reported in previous studies. Years of life lost (YLLs) were calculated to quantify disease burden in relation to premature deaths. Mitigation effects were examined under scenarios in which all homes with indoor radon concentrations above a specified level were remediated below the level. RESULTS: The estimated number of lung cancer deaths attributable to indoor radon exposure ranged from 1946 to 3863, accounting for 12.5–24.7% of 15623 total lung cancer deaths in 2010. YLLs due to premature deaths were estimated at 43140–101855 years (90–212 years per 100000 population). If all homes with radon levels above 148 Bq/m3 are effectively remediated, 502–732 lung cancer deaths and 10972–18479 YLLs could be prevented. CONCLUSION: These findings suggest that indoor radon exposure contributes considerably to lung cancer, and that reducing indoor radon concentration would be helpful for decreasing the disease burden from lung cancer deaths.

ABSTRACT

Fecal samples were collected from 120 domestic pigeons to determine the Attributable risk of Capillaria spp. The Capillaria spp. was observed in 64 out of 120 (51%) pigeons (70 males and 50 females) under this study. A total of 64 (39 males and 25 females) were found naturally infected with Capillaria spp. with infection percentage of 51% and 50% in males and females respectively. Qualitative examinations include the direct microscopy and faecal floatation while quantitative examination includes McMaster technique (worms load was calculated per gram of the faeces). Month wise Attributable risk showed that eggs of the worms were found to be abundant in the month of July during the present study (60% to 73%) because of high humidity. Very high and very low temperature is not suitable for the proper development of the eggs. Qualitative and quantitative examination revealed that Capillaria spp. was more prevalent in males (51%) than females (50%) but overall there was no significant difference (P>0.05) in the male and female because both individuals invest equal amount of energy in search of food and incubating the eggs. Different breeds of pigeons gave different Attributable risk in different months during the study. Groups of pigeons from different locations showed different variable Attributable risk. Areas with high humidity were more suitable for the development of eggs, which is the reason why higher Attributable risk was observed in Shahdara (75%) area of Lahore, Pakistan.(AU)


Amostras de fezes foram coletadas de 120 pombos domésticos para determinar os fatores de risco de Capillaria spp. Capillaria spp. foi observado em 64 de 120 (51%) pombos (70 machos e 50 fêmeas) neste estudo. Um total de 64 (39 machos e 25 fêmeas) foram naturalmente infectados com Capillaria spp. sendo 51% em machos e 50% em fêmeas. Exames qualitativos incluem microscopia direta e suspensão de fezes, e exames quantitativos incluem a técnica McMaster (vermes são calculados por grama de fezes). O risco por mês demonstrou que ovos dos vermes foram encontrados em abundância no mês de Julho durante o presente estudo (60% a 73%) por causa da alta umidade. Temperaturas muito altas e muito baixas não são adequadas para o desenvolvimento adequado de ovos. O exame qualitativo e quantitativo revelou que Capillaria spp. era mais prevalente em machos (51%) que em fêmeas (50%), mas no geral não houve diferença significativa (P>0.05) entre machos e fêmeas porque ambos investem a mesma energia na busca por alimento e incubação de ovos. Diferentes raças de pombos tem diferentes riscos em diferentes meses durante o estudo. Grupos de pombos de diferentes locais demonstraram risco diferenciado. Áreas com alta umidade eram mais propensas para o desenvolvimento de ovos, o motivo pelo qual maior risco foi observado em shahdara (75%).(AU)

ABSTRACT

Objective To study the influence of daily air temperature on daily chronic obstructive pulmonary disease (COPD) mortality in residents in Ningbo. Methods A time-series analysis using distributional lag non-linear model (DLNM) was conducted to estimate the attributable numbers and fraction of average air temperature on the daily COPD mortality in Ningbo from 2011 to 2016, by controlling the long-term time trend, day of week, air pollutants and other weather variables. Results A reverse J-shape relationship was found between the average air temperature and COPD mortality, and the minimum-mortality temperature (MMT) was 25.5℃. The relative risks of extreme low and extreme high air temperature over lag 0-14 d were 2.767 (95%CI: 1.950-3.928) and 1.197 (95%CI:1.021-1.404). In total, 31.62%(95%CI:23.05%-38.89%) of COPD mortality (4963 cases, 95%CI: 3469-6027) was attributable to non-MMT exposure, More attributable deaths were due to low air temperature, with a fraction of 30.41%corresponding to 4772 deaths, compared with 1.22%and 192 deaths due to high air temperature. Low air temperature and high temperature were more likely to influence the mortality in females and those aged ≥65 years, but the influence was not significant in people aged <65 years. Conclusion Both high and low air temperature were associated with an increased risk of COPD mortality in residents in Ningbo, especially during cold season, related measures on disease prevention should be taken to protect vulnerable population to reduce the risk of COPD mortality.

ABSTRACT

ABSTRACT Objective To estimate annual infant morbidity and mortality attributable to prenatal smoking in Chile during 2008−2012. Methods Population-attributable fractions (PAFs) for several infant outcomes were calculated based on previous study estimates of prenatal smoking prevalence and odds ratios associated with exposure (prenatal smoking relative to non-prenatal smoking). Prenatal smoking-attributable infant morbidity and mortality cases were calculated by multiplying the average annual number of morbidity and mortality cases registered in Chile during 2008-2012 by the corresponding PAF. Results PAFs for 1) births ≤ 27 weeks; 2) births at 28-33 weeks; 3) births at 34-36 weeks; and 4) full-term low-birth-weight infants were 12.3%, 10.6%, 5.5%, and 27.4% respectively. PAFs for deaths caused by preterm-related causes and deaths caused by sudden infant death syndrome were 11.9% and 40.0% respectively. Annually, 2 054 cases of preterm-birth and full-term low-birth-weight (1 in 9 cases), 68 deaths caused by preterm-related causes (1 in 8 cases), and 26 deaths caused by sudden infant death syndrome (1 in 3 cases) were attributable to prenatal smoking. Conclusions In Chile, infant morbidity and mortality attributable to prenatal smoking are unacceptably high. Comprehensive individual and population-based interventions for tobacco control should be a public health priority in the country, particularly among female adolescents and young women who will be the mothers of future generations.


RESUMEN Objetivo Calcular las tasas anuales de morbilidad y mortalidad de lactantes atribuibles al tabaquismo prenatal en Chile entre los años 2008 y 2012. Métodos Se calcularon las fracciones atribuibles a la población (FAP) correspondientes a diferentes resultados de salud en lactantes tomando como base la prevalencia estimativa del tabaquismo prenatal y las razones de posibilidad asociadas a la exposición (tabaquismo prenatal frente a tabaquismo no prenatal) calculadas en estudios previos. Los casos de mortalidad y morbilidad de lactantes atribuibles al tabaquismo prenatal se calcularon multiplicando el promedio anual de casos de morbilidad y mortalidad registrados en Chile entre los años 2008 y 2012 por la FAP correspondiente. Resultados Las FAP para los lactantes nacidos 1) a las 27 semanas o menos de gestación; 2) de 28 a 33 semanas de gestación; 3) de 34 a 36 semanas de gestación; y 4) al término de la gestación, pero con peso bajo al nacer, fueron de 12,3%, 10,6%, 5,5% y 27,4%, respectivamente. Las FAP correspondientes a las muertes por causas relacionadas con el nacimiento prematuro y las muertes por síndrome de muerte súbita del lactante fueron de 11,9% y 40,0%, respectivamente. Al año, 2 054 casos de bebés prematuros y de bebés nacidos con peso bajo al término de la gestación (1 de 9 casos), 68 muertes por causas relacionadas con el período prenatal (1 de 8 casos) y 26 muertes causadas por el síndrome de muerte súbita del lactante (1 de 3 casos) fueron atribuibles al tabaquismo prenatal. Conclusiones En Chile, las tasas de morbilidad y mortalidad de lactantes atribuibles al tabaquismo prenatal son inadmisiblemente altas. En el país, las intervenciones integrales para el control del tabaco a nivel individual y poblacional deben ser una prioridad de salud pública, particularmente en las mujeres adolescentes y jóvenes que serán las madres de las generaciones futuras.


RESUMO Objetivo Estimar a morbidade e a mortalidade infantis anuais atribuíveis ao tabagismo durante a gestação no Chile em 2008-2012. Métodos As frações atribuíveis populacionais (PAFs) para vários desfechos infantis foram calculadas com base em estimativas de estudos anteriores da prevalência do tabagismo durante a gestação e razões de possibilidades associadas à exposição (tabagismo durante a gestação relativo ao tabagismo fora da gestação). Os casos de morbidade e mortalidade infantis atribuíveis ao tabagismo durante a gestação foram calculados multiplicando-se o número médio anual de casos de morbidade e mortalidade registrados no Chile em 2008-2012 pela PAF correspondente. Resultados As PAFs para 1) recém-nascidos ≤ 27 semanas, 2) recém-nascidos com 28-33 semanas, 3) recém-nascidos com 34-36 semanas e 4) recém-nascidos de termo com baixo peso foram 12,3%, 10,6%, 5,5% e 27,4%, respectivamente. As PAFs para mortes devidas a causas relacionadas à prematuridade e mortes devidas à síndrome de morte súbita do recém-nascido foram 11,9% e 40,0%, respectivamente. Anualmente, 2.054 casos de recém-nascidos prematuros e de termo com baixo peso (1 em 9 casos), 68 mortes devidas a causas relacionadas à assistência pré-natal (1 em 8 casos) e 26 mortes devidas à síndrome de morte súbita do recém-nascido (1 em 3 casos) foram atribuíveis ao tabagismo durante a gestação. Conclusões No Chile, a morbidade e a mortalidade infantis atribuíveis ao tabagismo durante a gestação são inadmissivelmente elevadas. Amplas intervenções individuais e populacionais para o controle do tabagismo devem ser uma prioridade de saúde pública no país, sobretudo em adolescentes e jovens que serão mães das futuras gerações.

ABSTRACT

Objective To evaluate risk and the direct economic burden of malignant tumor due to type 2 diabetes mellitus. Methods Combing the data of chronic disease surveillance, follow-up and the fifth health service investigation, we calculated the population attributable risk and the direct economic burden for malignant tumor due to type 2 diabetes mellitus in order to estimate the direct economic burden for tumor caused by type 2 diabetes mellitus. Results The relative risk was 1.68 (95%CI: 1.68-1.70) for people with type 2 diabetes mellitus to develop the malignant tumor than the people without type 2 diabetes mellitus. The proportions of attributable risk (AR%) and population attributable risk (PAR%) were 40.57% and 2.05%, respectively. Moreover, the annual average hospitalization costs for malignant tumor reached 11 billion CNY, which took part 6.48% of total health service costs. And the direct economic burden for malignant tumor due to type 2 diabetes mellitus was 0.228 billion CNY. In addition, the top two highest population attributable risks were colorectal cancer and liver cancer, while the top three greatest direct economic burdens for malignant tumor or malignant tumor due to type 2 diabetes mellitus were lung cancer, colorectal cancer and stomach cancer. Conclusion From this study, we found that type 2 diabetes mellitus increased the risks of tumor and therefore lead to sharply increasing in medical costs of malignant tumor. In order to decrease the risk of malignant tumor and medical costs, we should pay more attention to the prevention of type 2 diabetes mellitus and the screening of malignant tumor due to type 2 diabetes mellitus.
