@#Objective To analyze the related knowledge-attitude-practice(KAP)and the influencing factors of human papilloma virus(HPV)vaccine among 16 — 45 year old resident women in Pudong New Area.Methods Six of the 36streets(towns)in Pudong New Area were randomly selected as the survey site,the resident women aged 16 — 45 years were randomly selected excluding those with reading or comprehension disabilities and those with mental disorders,and a total of 1 022 valid questionnaires were collected through self-filling questionnaires to understand the KAP status of the HPV vaccine among the resident women in Pudong New Area. The relationship among KAP of HPV vaccine and its influencing factors were analyzed by univariate analysis and structural equation model.Results The overall awareness rate of HPV vaccine among 16-45 year old resident women in Pudong area was higher. Univariate analysis showed that marital status,educational level,employment status and household annual income were related to the awareness level of HPV vaccine（χ~2=12. 832,17. 636,16. 770 and 20. 030,respectively,each P < 0. 05）;Age,marital status,employment status and children′s status were correlated with HPV vaccination level（χ~2= 12. 382,25. 777,8. 830 and 20. 138,respectively,each P <0. 05）;HPV vaccine health education,HPV and HPV vaccine knowledge scores affected HPV vaccination status（χ~2=97. 561 and 68. 969,respectively,P < 0. 001）;Subjects' knowledge of cervical cancer was positively affected by knowledge of HPV infection(γ_(11)= 0. 756,P < 0. 001). Knowledge of cervical cancer not only positively affected subjects′ attitudes towards the efficacy of HPV vaccine(β_(21)= 0. 557,P < 0. 001),also had a direct effect on the HPV vaccination behavior of the subjects,showing a promoting effect(β_(31)= 0. 274,P = 0. 004). Subjects′ approval of the efficacy of HPV vaccine had a positive effect on their actual vaccination behavior(β_(32)= 0. 175,P = 0. 016).Conclusion The willingness of the 16 — 45 year old resident women in Pudong New Area to inoculate HPV vaccine was positive,but the actual vaccination rate was low. It is suggested to strengthen the HPV vaccine publicity while strengthening the education of cervical cancer and HPV infection,and consider the necessity of including the suitable age males in the scope of human vaccination.

Comparison of Quality Change During Processing Process of Achyranthis Bidentatae Radix from Different Origins Based on Color-component Correlation Analysis / 中国实验方剂学杂志

ObjectiveTaking Achyranthis Bidentatae Radix（ABR） from different origins as samples， to quantitatively analyze the chemical composition and chromaticity of ABR with different processing degrees， and clarify the correlation and change law between color and composition in the processing process of ABR， so as to provide reference for the quality evaluation of processed products of ABR. MethodThe colorimeter is used to measure the chromaticity values of three kinds of processing degrees of ABR in different origins to show the color value change trend during the processing process， and the color parameters of wine-processed and salt-processed products of ABR with different processing degrees were analyzed by principal component analysis（PCA）， orthogonal partial least squares-discriminant analysis（OPLS-DA） and other analysis methods. The contents of eight representative components of ABR were measured by high performance liquid chromatography（HPLC）， the correlation between chromaticity and each representative component was analyzed by Pearson correlation analysis， and the applicability of the selected eight representative components was further verified by Fisher linear discriminant analysis， and the wine-processed and salt-processed products of ABR with different processing degrees were grouped according to the degree of processing， and 48 samples of wine-processed and salt-processed products with different processing degrees were used as training samples. Taking the contents of 5-hydroxymethylfurfural， polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone， ginsenoside Ro， chikusetsusaponin Ⅳa and polysaccharides as variables， the discriminant function was established respectively， and 12 samples of wine-processed and salt-processed products of ABR with different processing degrees were back-tested to verify the discriminant function and test the reliability of the function. ResultPCA and OPLS-DA results showed that ABR samples with different processing degrees were classified into clusters， and the results could significantly distinguish different processed products. During the process of wine and salt processing， the contents of 5-hydroxymethylfurfural， ginsenoside Ro， and chikusetsusaponin Ⅳa gradually increased with the deepening of the processing degree， while the contents of polypodine B， β-ecdysterone， 25R-inokosterone， 25S-inokosterone and polysaccharides showed a gradual decreasing trend， indicating these 8 components increased and decreased to different degrees in the process of wine and salt processing. The results of Pearson correlation analysis showed that the 5-hydroxymethylfurfural content of the samples with different processing degrees of wine-processed and salt-processed products were negatively correlated with the brightness value（L*） and the total color difference value（E*ab）（P<0.01）， and positively correlated with the red-green value（a*） and the yellow-blue value（b*）（P<0.01）， and that the content of polypodine B and polysaccharides were positively correlated with L* and E*ab（P<0.01）. The discriminant functions of wine-processed and salt-processed products of ABR were established by Fisher linear discriminant analysis， and their accuracy rates in the training samples were 93.75% and 95.83%， respectively. Twelve test samples of wine-processed and salt-processed products with different processing degree were back substitution， and the correct rate was 100%. ConclusionThe trend of composition and color changes of ABR with different processing degrees in different production areas is relatively consistent， and the color value can better distinguish ABR with different processing degrees， and the color of ABR is related to some representative components in the processing process， indicating that the color can provide reference for the identification of the processing degree of ABR and the prediction of component content.

Herbal Textual Research on Tsaoko Fructus in Famous Classical Formulas / 中国实验方剂学杂志

This article systematically analyzes the historical evolution of the origin， scientific name， medicinal parts， quality evaluation， harvesting and processing and other aspects of Tsaoko Fructus by consulting ancient materia medica， medical books， prescription books in the past dynasties and combining with the modern literature， so as to provide a basis for the development and utilization of famous classical formulas containing Tsaoko Fructus. According to the research， the name of Caoguo（草果） was first used in the Taiping Huimin Heji Jufang（《太平惠民和剂局方》） in the Northern Song dynasty， Tsaoko Fructus is the correct name of the herbal medicine in all dynasties， and there are also aliases such as Caokou， Doukou， Loukou， Laokou and Caodoukou. The mainstream source of Tsaoko Fructus used in the past dynasties is the dried mature fruit of Amomum tsaoko of Zingiberaceae， but Tsaoko Fructus was often used as a nickname for Amomi Fructus Rotundus or Alpiniae Katsumadai Semen during the Song dynasty. Bencao Pinhui Jingyao（《本草品汇精要》） in the Ming dynasty was the earliest materia medica that recorded Tsaoko Fructus as a separate medicinal herb in sections. Under the influence of early ancient books， there were some books that confused Tsaoko Fructus with other Zingiberaceae plants during the Qing dynasty， it was not until modern times that Tsaoko Fructus was distinguished from other plants. The origin of Tsaoko Fructus is Yunnan and Guangxi， and then gradually expanded to Guizhou and other places. Now Yunnan is the province with the largest planting area of Tsaoko Fructus， and has become the main producing area. Since modern times， it has been recorded in the literature that the quality of Tsaoko Fructus is mainly characterized by large， full， red-brown and strong in smell. According to ancient records， the harvest time of Tsaoko Fructus was in the eighth month of the lunar calendar， and they were mostly used for peeling or simmering. Currently， the harvest period of Tsaoko Fructus is October to November， and then sun-dried or dried after harvesting. The records of the properties and functional indications of Tsaoko Fructus are basically consistent with the ancient and modern documents， which is warm in nature， pungent in flavor， belonging to the spleen and stomach meridians， moderate in dryness and dampness， intercepting malaria and eliminating phlegm， used for internal resistance of cold and dampness， abdominal distension and pain， fullness and vomiting， malaria cold and fever， and plague fever. Based on the research results， it is suggested that A. tsaoko should be used as the medicinal base for the development of famous classical formulas containing Tsaoko Fructus， processing method can be according to the requirements of the prescription， and if the requirements of concoction are not indicated， it can be used in the form of raw products.

Herbal Textual Research on Bletillae Rhizoma in Famous Classical Formulas / 中国实验方剂学杂志

In order to provide basic information for the utilization and development of famous classical formulas containing Bletillae Rhizoma， this article systematically analyzes the historical evolution of the name， origin， harvesting and processing of Bletillae Rhizoma by reviewing the ancient materia medica， prescription books， medical books and modern literature. The research results showed that Baiji（白及） was the main name， some scholars took Baiji（白芨） as its main name， and there were many other names such as Baiji（白给）， Baigen（白根）， Baiji（白苙）. The mainstream source of Bletillae Rhizoma was the tubers of Bletilla striata， and drying， large， white， solid， root-free and skin removed completely were the good quality standards. With the promotion of wild to cultivated medicinal materials， there were certain differences between their traits， and the quality evaluation indexes should be adjusted accordingly. The origin of records in the past dynasties was widely distributed， with Guizhou and Sichuan having high production and good quality in modern times. The harvesting period is mostly in spring and autumn， and harvested in autumn was better. The processing and processing technology is relatively simple， and it was used fresh or powdered in past dynasties， while it is mainly sliced for raw use in modern times. Based on the results， it is suggested that the tubers of Bletilla striata of Orchidaceae should be used in the famous classical formulas， and it should be uniformly written as Baiji（白及）. And if the original formula indicates the requirement of processing， it should be operated according to the requirement， if the requirement of processing is not indicated， it can be used in raw form as medicine.

ObjectiveTo clarify the scientific validity of in vivo pharmacokinetic determination of the whole drug composition in Shenbai nanosuspension in rats， and to provide methodological guidance and theoretical basis for the in vivo study of multi-component complex system of traditional Chinese medicine（TCM） preparations. MethodThe concentration of the overall components， mainly total saponins and total polysaccharides in Shenbai decoction and Shenbai nanosuspension， was determined in rat plasma at different times by area under the absorbance-wavelength curve method（AUAWC）， and the concentration of individual ginsenoside Rg1 was determined by high performance liquid chromatography（HPLC）， and the methodology was verified. The pharmacokinetic parameters of the whole component were compared with those of ginsenoside Rg1 to evaluate the in vivo operational characteristics of the two preparations. ResultThe methodological investigations of AUAWC and HPLC were in accordance with the requirements. AUAWC analysis showed that the overall components in both the decoction group and the nanosuspension group showed a one-compartment model， with half-life（t1/2） of 2.43 h and 2.04 h， respectively. The relative bioavailability of Shenbai nanosuspension was 138.99%. HPLC assay showed that ginsenoside Rg1 in the decoction group and the nanosuspension group showed a two-compartment model， with distribution half-life（t1/2α） of 0.13 h and 2.55 h， and elimination half-life（t1/2β） were 14.28 h and 3.85 h， respectively. The relative bioavailability of Shenbai nanosuspension was 127.49%. Compared with Shenbai decoction， the time to peak（tmax）， peak concentration（Cmax） and area under the drug-time curve（AUC） of the overall components and ginsenoside Rg1 in Shenbai nanosuspension were increased. ConclusionThe established AUAWC can be used for the pharmacokinetic study of the overall components of TCM preparations， which is complementary to the results of individual components measured by HPLC， and can provide useful reference for the in vivo study of new dosage forms of TCM.

Evaluation of Relationship of Pueraria lobata Quality from Different Producing Areas Based on "Climate Factor-component Content-antioxidant Capacity" / 中国实验方剂学杂志

ObjectiveThe correlation of Pueraria lobata producing areas， climate factors， total flavonoids of P. lobata， polysaccharide content of P. lobata， and antioxidant activity of P.lobata for medicinal application was analyzed， and the relationship between climate factors and the formation of P. lobata quality was evaluated. MethodThe scavenging rates of 1,1-diphenyl-2-picrylhydrazyl radical 2,2-diphenyl-1-(2,4,6-trinitrophenyl)hydrazyl（DPPH） and 2, 2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)（ABTS） radicals by total flavonoids and polysaccharides of P. lobata were detected， and the correlation between the contents of each component and the information of producing areas and climate factors was analyzed. ResultThe ABTS+ scavenging rate by total flavonoids of P.lobata was negatively correlated with altitude （P<0.05） and positively correlated with annual sunshine hours （P<0.05）. The altitude was positively correlated with the total flavonoid content， while the annual sunshine hours were negatively correlated with the total flavonoid content. There was a negative correlation between total flavonoid content and ABTS+ scavenging rate by total flavonoids. In other words， lower altitude and longer annual sunshine hours indicated lower total flavonoid content and higher ABTS+ scavenging rate by total flavonoids. The ABTS+ scavenging rate by polysaccharides of P. lobata was negatively correlated with the frost-free period （P<0.05） and the mean temperature in July （P<0.01）. There was a positive correlation between the polysaccharide content of P. lobata and the frost-free period. The mean temperature in July was positively correlated with the polysaccharide content of P. lobata （P<0.05）. The polysaccharide content of P. lobata was negatively correlated with the ABTS+ scavenging rate by polysaccharides of P. lobata. In other words， a shorter frost-free period in the producing area and lower mean temperature in July indicated lower polysaccharide content of P. lobata and higher ABTS+ scavenging rate by polysaccharides of P. lobata. The mean temperature in July was significantly correlated with the contents of total flavonoids and polysaccharides in P. lobata samples （P<0.05）. The lower mean temperature in July was often accompanied by lower total flavonoid content of P. lobata， lower polysaccharide content of Pueraria lobata， and stronger antioxidant activity of P. lobata samples. ConclusionThe ability of P. lobata to remove ABTS+ is stronger than that of DPPH+. There is a significant correlation between climate factors， content， and antioxidant capacity in each producing area. Further research on the internal law of the formation of medicinal active components of P. lobata induced by core climate factors will provide a scientific basis for revealing the formation mechanism of genuine P. lobata and the subsequent control of P. lobata quality according to the environment of producing areas.

Disease burden due to PM2.5 pollution before and after air quality improvement in Shijiazhuang / 环境与职业医学

Background Air pollution has gradually become a major environmental and public health problem faced by countries around the world. Hazy weather not only affects the health of the population, but also poses a threat to social and public safety. China has successively promulgated policies such as the "Ten Articles on Atmosphere" and the Three-year action plan to fight air pollution, aiming to improve ambient air quality. It is clear that the Beijing-Tianjin-Hebei region has accomplished the set targets and improved air quality according to the environmental monitoring data of 2017. Objective To assess air quality improvements through the evaluation of the disease burden due to fine particulate matter (PM2.5) pollution in Shijiazhuang City before and after the air quality improvement from 2014 to 2021, including fatalities and health economic losses attributed to PM2.5 pollution. Methods Data on causes of death, PM2.5 concentrations, the number of permanent residents at the end of the year, gross regional product, and disposable income per capita in urban areas of Shijiazhuang were collected from 2014 to 2021. Total, non-accidental, circulatory, and respiratory deaths due to PM2.5 pollution were estimated by global exposure mortality models (GEMM). Health and economic losses due to selected diseases were calculated by value of statistical life (VOSL). Results During the study period, the average annual concentration of PM2.5 in Shijiazhuang was highest in 2014, and began to decline year by year in 2017, but all exceeded the current national limit of the second level of ambient air quality standards (35 μg·m−3). The total deaths, non-accidental deaths, circulatory disease deaths, and respiratory disease deaths attributed to PM2.5 pollution from 2014 to 2021 were 41326, 40246, 21792, and 5022, respectively; the associated health economic losses were 37.362, 36.369, 19.695, and 4.535 billion yuan, respectively. From the perspective of improved air quality, both the number of attributed deaths and health economic losses had declined in a volatile manner since 2017, with a significant decrease in 2019. If the average annual concentration of PM2.5 reached the second-level limit of China's ambient air quality standard (35 μg·m−3), the total deaths, non-accidental deaths, and deaths from circulatory diseases and respiratory diseases due to PM2.5 pollution would deducted by about 17000, 16000, 9000, and 2000, respectively; the corresponding health and economic losses would decreased by 15.201, 14.761, 7.959, and 1.859 billion yuan, respectively. If the average annual concentration of PM2.5 reached the latest PM2.5 air quality guidelines (5 μg·m−3) proposed by the World Health Organization, the total deaths, non-accidental deaths, circulatory disease deaths, and respiratory disease deaths due to PM2.5 pollution would deducted by 36000, 35000, 19000, and 4000, respectively, and the corresponding health and economic losses would reduced by 32.673, 31.796, 17.211, and 3.969 billion yuan, respectively. Conclusion PM2.5 pollution can lead to severe mortality burden and economic loss. Under the implementation of the State Council's "Ten Articles on Atmosphere" and the Three-year action plan to fight air pollution, Shijiazhuang's PM2.5 concentration and health economic losses have been significantly reduced, and further control of PM2.5 pollution can achieve greater health benefits and economic gains, affirming the positive results of local air pollution prevention work.

ObjectiveTo analyze the effects of new integration processing method in producing area and traditional method on the composition and pharmacological action of Polygoni Multiflori Radix Praeparata（PMRP）， and to illustrate the advantages of toxicity reducing and efficacy enhancing of the decoction pieces prepared by the new method. MethodFresh Polygoni Multiflori Radix（PMR） was taken from Dao-di producing area， and was processed by new integration processing method in producing area（steaming with black bean juice under pressure of 0.1 MPa and temperature at 120 ℃ for 10.5 h） and traditional method（steaming with black bean juice under water for 36 h）， respectively. Samples were collected during the processing process of the two methods， For new method， the samples were collected at 0.5， 3， 5.5， 8， 10.5 h， separately. For traditional method， the samples were collected every 4 h. High performance liquid chromatography（HPLC） was used to establish fingerprint and identify common peaks， the content of polysaccharides was determined by anthrone-sulfuric acid colorimetry at 627 nm， and the contents of anthraquinones and stilbene glycosides in different processed products were determined according to the methods under the item of determination of PMR and PMRP in the 2020 edition of Chinese Pharmacopoeia. In pharmacological experiments， 90 SD rats were randomly divided into 9 groups with 10 in each group（half of male and half of female）， including the blank group， and raw products， 24 h processed products under atmospheric pressure， 30 h processed products under atmospheric pressure， 8 h processed products under high pressure groups with low and high dosages（4.125， 16.5 g·kg-1）. Rats were given the drug by gavage for 29 d with once a day， blood was collected from the abdominal aorta after the last administration， and the serum was isolated， the body mass and liver mass of rats were weighed and the organ index was calculated. The pathological change of liver tissue was observed by hematoxylin-eosin（HE） staining， and biochemical methods were used to detect the contents of aspartate aminotransferase（AST）， alanine aminotransferase（ALT）， alkaline phosphatase（ALP）， γ-glutamyltransferase（GGT）， lactic dehydrogenase（LDH） in serum which used as liver function indicators and the levels of superoxide dismutase（SOD）， malondialdehyde（MDA）， glutathione peroxidase（GSH-Px） in brain tissues which used as oxidation indicators. ResultA total of 14 common peaks were identified in the fingerprint of PMR， PMRP prepared by new method and traditional method， and three of the peaks were designated as stilbene glycoside， emodin and emodin methyl ether， respectively. The characteristic peak areas of each processed products changed significantly from 0 min to 25 min， indicating that different processing methods had an effect on the contents of components with high polarity in PMRP， and the trend of the changes of the two methods was similar， with the higher degree of change in the new method. The determination results showed that compared with the traditional method， the content of polysaccharide（a kind of beneficial component in PMRP obtained by the new method） significantly increased， while the contents of stilbene glycoside and bound anthraquinone（liver-damaging ingredients） significantly decreased. The pharmacological results showed that compared with the blank group， AST and LDH levels of male rats in the low and high dose groups of 24 h processed products under atmospheric pressure and AST level of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly reduced（P<0.05， P<0.01）， while compared with the raw product groups with the same dose， AST and LDH levels of male rats in the low dose group of 30 h processed products under atmospheric pressure were significantly reduced（P<0.05， P<0.01）， the AST levels of male rats in the low and high dose groups of 8 h processed products under high pressure were significantly decreased（P<0.01）， and there was no statistical significance in the differences of biochemical indexes of female rats in each administration group as compared with those of the blank group. ConclusionThe new integration processing method in producing area of PMRP can reach the quality of relevant regulations in 8 h. The processed products obtained by this method have more advantages than the traditional method in terms of toxicity reducing and efficacy enhancing， and energy saving to avoid the loss of ingredients， which can provide ideas for the production of high-quality decoction pieces of PMRP， and the integration processing method in producing area of other roots and rhizomes of traditional Chinese medicines.

There was no significant difference between prevalence of elevated blood pressure screened by formula method, sex and age specific method and gold standard( χ 2=1.21, 1.41, P >0.05), whereas height specific method and age group specific method had significant differences with gold standard ( χ 2=20.39, 67.09, P <0.05). AUC was the largest for height specific method [0.94(95% CI =0.93-0.95)], and the smallest for age group specific method [0.87(95% CI = 0.86 -0.88)]. The Kappa values of height specific method (0.89) and sex and age specific method (0.89) were both greater than 0.85 , which were more consistent with the screening effectiveness of gold standard. When comparing by sex, age and body mass index (BMI), the screening effectivenesses were consistent with the overall in boys, 6-11 years and normal body weight groups, while the screening effectivenesses were different in girls, 12-17 years, overweight and obese groups. The AUC (0.87), Kappa value (0.71) and sensitivity (82.33%) of age group specific method were the lowest and the screening effectiveness was the worst.@*Conclusion@#Height specific method is more effective and can be used for early identification and self detection of blood pressure abnormalities among children and adolescents.

Cut-off points of neck and waist circumference as predictors of obstructive sleep apnea in the Colombian population: a comparison with polysomnography

ABSTRACT BACKGROUND: Neck circumference (NC) is a useful anthropometric measure for predicting obstructive sleep apnea (OSA). Ethnicity and sex also influence obesity phenotypes. NC cut-offs for defining OSA have not been established for the Latin American population. OBJECTIVES: To evaluate NC, waist circumference (WC), and body mass index (BMI) as predictors of OSA in the Colombian population and to determine optimal cut-off points. DESIGN AND SETTING: Diagnostic tests were conducted at the Javeriana University, Bogota. METHODS: Adults from three cities in Colombia were included. NC, WC, and BMI were measured, and a polysomnogram provided the reference standard. The discrimination capacity and best cut-off points for diagnosing OSA were calculated. RESULTS: 964 patients were included (57.7% men; median age, 58 years) and 43.4% had OSA. The discrimination capacity of NC was similar for men and women (area under curve, AUC 0.63 versus 0.66, P = 0.39) but better for women under 60 years old (AUC 0.69 versus 0.57, P < 0.05). WC had better discrimination capacity for women (AUC 0.69 versus 0.57, P < 0.001). There were no significant differences in BMI. Optimal NC cut-off points were 36.5 cm for women (sensitivity [S]: 71.7%, specificity [E]: 55.3%) and 41 cm for men (S: 56%, E: 62%); and for WC, 97 cm for women (S: 65%, E: 69%) and 99 cm for men (S: 53%, E: 58%). CONCLUSIONS: NC and WC have moderate discrimination capacities for diagnosing OSA. The cut-off values suggest differences between Latin- and North American as well as Asian populations.

Avaliação de indicadores sociais e de saúde em municípios de Minas Gerais conforme tipologia rural-urbano / Assessment of social and health indicators in municipalities of Minas Gerais according to the rural-urban typology

RESUMO O presente artigo tem o objetivo de avaliar indicadores sociais e de saúde de municípios conforme a tipologia rural-urbano. Trata-se de estudo ecológico que utilizou dados oficiais de acesso público dos 853 municípios do estado de Minas Gerais, Brasil. Foram conduzidas análises descritivas e bivariadas através da Regressão de Poisson e Teste de Kruskal-Wallis. Do total de municípios, 547 (64,12%) são rurais. A maior média do Índice de Desenvolvimento Humano Municipal (IDH-M) foi observada entre os municípios urbanos. A maior média de cobertura da Estratégia Saúde da Família (ESF) foi verificada entre os municípios rurais, nos quais também foram demonstrados os melhores resultados para os indicadores de mortalidades infantil, prematura e por causas evitáveis, homogeneidade vacinal e prevalência de desnutrição. Os achados deste estudo evidenciam que uma maior cobertura da ESF está associada à ocorrência de melhores condições gerais de vida e de saúde das populações atendidas em municípios de tipologia rural. Recomenda-se aos gestores de saúde o fomento à consolidação da ESF em comunidades com contextos socioeconômicos e culturais desfavoráveis, como localidades rurais remotas e aglomerados urbanos, e o estabelecimento de ações intersetoriais com impacto positivo na saúde.

ABSTRACT This article aims to evaluate social and health indicators of municipalities according to the rural-urban typology. This is an ecological study that used official publicly accessible data from the 853 municipalities in the state of Minas Gerais, Brazil. Descriptive and bivariate analysis were carried out using Poisson Regression and Kruskal-Wallis Test. 547 (64.12%) are rural municipalities. The highest average of the Municipal Human Development Index (MHDI) was observed among urban municipalities. The highest average coverage of the Family Health Strategy (FHS) was found among rural municipalities. In these municipalities, the best results were shown for the indicators of infant mortality, premature mortality and mortality from preventable causes, vaccine homogeneity and prevalence of malnutrition. The findings of this study show that greater FHS coverage is associated with the occurrence of better general living and health conditions in the populations served in rural municipalities. It is recommended that health managers encourage the consolidation of the FHS in communities with unfavorable socioeconomic and cultural contexts, such as remote rural locations and urban agglomerations, and the establishment of intersectoral actions with a positive impact on health.

Prevalence and associated factors of malnutrition among under-five children living in slum areas of Bahir Dar Town, Ethiopia

Introduction: child malnutrition is one of the most serious and least addressed health problems in the world and in Ethiopia. The prevalence of malnutrition, underweight, and wasting was 44%, 29%, and 10% respectively. The Amhara region has the highest rates of malnutrition at 52%, 33.4%, and 9.9% for children under five. The aim of this study was to assess the prevalence of malnutrition and its associated factors among children under five living in the slum areas of Bahir Dar City. Methods: a community-based cross-sectional study was conducted with 680 children aged 6-59 months in slum areas of Bahir Dar Town. Study participants were selected using a mass sampling technique and data were collected from April to June 2018 using a pre-tested structured questionnaire and anthropometric measurements. Finally, the collected data were coded, entered, cleaned, recorded, and stored, and the data were processed using EPI INFO and exported to the SPSS version 25.0 statistical package. Logistic regression analysis and interpretation were performed using bivariate and multivariate analysis. Results: a total of 680 children participated. The prevalence of lameness, underweight, and wasting was 46.2% (95% CI; 42.5-49.1), 24.3% (95% CI; 21.2-27.6), and 11.3% ( 95% CI; CI; 9.2-13.9). Income groups included children [AOR=3.476 (95% CI, 1.959-6.167)], male children [AOR=2.586 (95% CI; 1.532-4.365)] and mother's educational level [(AOR=2.600) (1.623) - 4.164)] were significantly associated with malnutrition. Conclusion: the results of this study showed that the prevalence of malnutrition due to stunting and wasting was high among children under five years of age. The gender of the child, the educational level of the mother, and the monthly income of the family were found to be significantly related to malnutrition. Promoting the use of family planning, preventing diarrheal diseases, and vaccinating children through nutrition education programs are important activities to improve the nutritional status of children.

Species diversity and spatial distribution of mosquitoes (Diptera: Culicidae) from La Isla Amazon Park, Napo Province, Ecuador / Diversidad de especies y distribución espacial de mosquitos (Diptera: Culicidae) del Parque Amazónico La Isla, provincia de Napo, Ecuador

Abstract Introduction: Vector-borne diseases are prevalent in the Amazon and Coastal regions of Ecuador. However, there is a scarcity of mosquito ecology studies in these areas. The most recent list of species reported for the country comprises 8 tribes, 22 genera, and 200 species. Objectives: To document the Culicidae species found in La Isla Amazon Park, Napo, Ecuador, including those with epidemiological significance; and to analyze their composition, abundance, and diversity, focusing on larval habitats during the dry and rainy periods. Methods: We evaluated different larval habitats, considering collection duration as the primary criterion. We used CDC and Shannon traps to collect adult mosquitoes during both rainy and dry periods. To assess sampling effort, we used accumulation curves and non-parametric estimators of species richness, while we employed Hill numbers to determine diversity. Additionally, we used the Berger-Parker and Pielou indices to evaluate species dominance and evenness. We conducted cluster analysis and ANOSIM tests to assess the similarity between habitats and the differences in taxonomic composition between periods. Results: We collected a total of 802 individuals from 15 species and 4 taxonomic units, 5 genera, and 4 tribes. Notably, this may be the first records of Wyeomyia felicia Dyar & Núñez Tovar and Culex derivator Dyar & Knab from Ecuador. Additionally, the presence of Culex dunni Dyar and Psorophora ferox von Humboldt (both recognized as vectors) was correlated with increased rainfall. Conclusions: The abundance of mosquitoes, including potential vector species, increased during the rainy season, indicating a higher risk of pathogen transmission. However, the relationship between rainfall amount and diversity patterns is not well-defined.

Resumen Introducción: Las enfermedades vectoriales son prevalentes en las regiones amazónica y costera de Ecuador. Sin embargo, hay una escasez de estudios de ecología de mosquitos en estas áreas. En el país se ha reportado 8 tribus, 22 géneros y 200 especies. Objetivos: Documentar las especies de Culicidae encontradas en el Parque Amazónico La Isla, Napo, Ecuador, incluyendo aquellas con importancia epidemiológica; y analizar su composición, abundancia y diversidad, enfocándose en los hábitats de las larvas durante los períodos seco y lluvioso. Métodos: Evaluamos diferentes hábitats larvarios, con la duración de la recolecta como criterio. Las trampas CDC y Shannon recolectaron mosquitos adultos durante los períodos seco y lluvioso. Evaluamos la riqueza de especies con curvas de acumulación y estimadores no paramétricos, mientras que determinamos la diversidad con los números de Hill. Además, utilizamos los índices de Berger-Parker y Pielou para evaluar la dominancia y la uniformidad de las especies. Realizamos análisis de conglomerados y la prueba ANOSIM para evaluar la similitud entre hábitats y estaciones, así como las diferencias en la composición taxonómica, respectivamente. Resultados: Recolectamos un total de 802 individuos de 15 especies y 4 unidades taxonómicas, 5 géneros y 4 tribus. Este podría ser el primer registro de Wyeomyia felicia Dyar & Núñez Tovar y Culex derivator Dyar & Knab en Ecuador. Además, la presencia de Culex dunni Dyar y Psorophora ferox von Humboldt (ambos potenciales vectores) se correlacionó con el aumento de las precipitaciones. Conclusiones: El aumento de la abundancia de mosquitos durante el periodo lluvioso indica un mayor riesgo de transmisión de patógenos. Sin embargo, la relación entre la cantidad de precipitaciones y los patrones de diversidad no está bien definida.

Resultados: se observó una asociación negativa entre la calidad de vida y los síntomas de depresión en todos los dominios, mientras que los síntomas de ansiedad tuvieron una asociación negativa en el dominio ambiente, y los síntomas de estrés tuvieron una asociación negativa en el dominio psicológico. La gravedad de los síntomas se asoció desfavorablemente con la calidad de vida, es decir, cuanto mayor la gravedad de los síntomas, menores las puntuaciones medias en todos los dominios. Conclusión: los síntomas de depresión, ansiedad y estrés fueron prevalentes e impactaron negativamente en la calidad de vida de los estudiantes, especialmente en presencia de síntomas depresivos. Las puntuaciones disminuidas se asociaron significativamente con la gravedad de los síntomas.

Objective: to evaluate the association between quality of life and presence of symptoms of depression, anxiety, and stress in college students in the health area. Method: cross-sectional study that included 321 students from undergraduate courses in the health area. Quality of life was measured using the World Health Organization scale, abbreviated version, in the physical, psychological, social relations and environment domains, and symptoms were assessed by the depression, anxiety and stress scale. Multivariate analysis was performed using robust linear regression to evaluate the association between quality of life and symptoms. Results: a negative association was observed between the quality of life and depression symptoms in all domains, while anxiety symptoms showed a negative association in the environment domain, and stress symptoms had a negative association in the psychological domain. Symptom severity was unfavorably associated with quality of life, that is, the greater the symptom severity, the lower the mean scores in all domains. Conclusion: symptoms of depression, anxiety, and stress were prevalent and had a negative impact on students' quality of life, especially in the presence of depressive symptoms. The decrease in scores was significantly associated with the severity of symptoms.
