Epidemiological data update and implications of chronic obstructive pulmonary disease for people older than 40 years in Yinchuan city / 中华健康管理学杂志

Objective:To survey and update the epidemiological data of chronic obstructive pulmonary disease (COPD) in people≥40 years old in Yinchuan City in the last 10 years.Methods:This was a cross-sectional study in which questionnaires and physical measurements were taken from April 2019 to December 2022 using multi-stage stratified whole population sampling of residents≥40 years in three districts, two counties, and one city in Yinchuan City. In this survey, 14 666 cases were extracted, and finally 11 547 cases with qualified lung function measurements and complete questionnaires were included in the analysis to obtain the basic information of the respondents, exposure to disease-related factors, symptoms related to COPD, disease awareness and lung function test rate, and logistic regression was used to analyze the risk factors of COPD.Results:A total of 11 547 cases were included in the study, and 1 841 patients with COPD were detected, giving an overall prevalence of COPD of 15.9%. The prevalence was higher in men (18.6%) than in women (12.9%); it was higher in urban areas (17.3%) than in rural areas (14.7%); and it was statistically significant that the prevalence of current smokers (24.4%) and ex-smokers (24.6%) was higher than the prevalence of non-smokers (13.0%) (all P<0.001) in those COPD patients. The prevalence rates of COPD in people aged 40-49, 50-59, 60-69, and ≥70 years were 11.7%, 12.9%, 16.9%, and 24.6%, respectively, which tended to increase gradually with age ( P<0.001). 10.5% of patients with COPD said they were aware of the disease and 17.4% received a pulmonary function test. The results of logistic regression analyses showed that the risk factors for COPD included male, advanced age, living in an urban area, low literacy, current smoking, former smoking, history of secondhand smoke exposure, low body weight, history of biomass fuel use, and family history of respiratory disease. Conclusions:The prevalence of COPD among people≥40 years in Yinchuan City is significantly higher than 10 years ago and is higher than the national data. However, the disease awareness rate is low, and active intervention of risk factors and enhancement of publicity are important measures to prevent and control the disease.

Domestic work and migration in the United States: a characterization of Honduran women / Trabalho doméstico e migração nos Estados Unidos: uma caracterização de mulheres hondurenhas / Trabajo doméstico y migración en los Estados Unidos: una caracterización de mujeres hondureñas

Abstract Given the lack of studies focused on Honduran domestic workers abroad, this article aims to characterize Honduran women living in the U.S. employed in domestic occupations. For this purpose, I employed survey data on women living in five American states, and calculated descriptive and inferential statistics. Furthermore, I employed binary logistic regression modeling to analyze the determinants of domestic work participation. When compared with all other occupations, domestic female workers of Honduran origin present significant differences in age, number of dependents, asset ownership, savings, income, and bank account ownership. Similarly, age (95% CI 0.92-2.63, p = 0.94), savings (95% CI 0.01-0.97, p = 0.047), account ownership in Honduras (95% CI 0.88-71.05, p = 0.064), monthly income (95% CI 0.99-1.00, p = 0.096), and social security (95% CI 0.02-1.29, p = 0.086) seem to be the key determinants explaining domestic work participation. Engaging and promoting compliance with international legal instruments might provide a means to consolidate the rights of these populations. The article concludes by highlighting future lines of research regarding the migration and rights of Honduras and Central American women living in the U.S.

Resumo Em função da escassa literatura sobre o tema, o presente artigo visa caracterizar as mulheres hondurenhas empregadas em ocupações domésticas nos Estados Unidos. Com esse objetivo, empregam-se questionários preenchidos por mulheres morando em cinco estados desse país norte-americano. Para realizar tal caracterização, é utilizada estatística descritiva e inferencial. Adicionalmente, emprega-se regressão logística para analisar os determinantes da participação em empregos domésticos. Quando comparadas com todas as outras ocupações, as mulheres hondurenhas fazendo trabalhos domésticos possuem diferenças em termos de idade, número de dependentes, posse de bens, poupanças e existência de conta bancária. Similarmente, a análise dos determinantes estatísticos mostra que variáveis significativas incluem idade (95% IC 0,92-2,63 p = 0.94), poupanças (95% IC 0,01-0,97, p = 0.047), existência de conta bancária (95% IC 0,88-71,05, p = 0.064), renda mensal (95% IC 0,99-1.00, p = 0.096) e contribuição à previdência social (95% IC 0,02-1,29 p = 0.086). Promover a adoção de instrumentos de direito internacional pode representar uma alternativa para fomentar os direitos humanos desse grupo de pessoas. O artigo finaliza ressaltando possíveis linhas de pesquisa relacionadas à migração de mulheres hondurenhas e da América Central morando nos Estados Unidos.

Resumen En vista de la escasa literatura centrada en trabajadoras domésticas hondureñas en el extranjero, el presente artículo busca caracterizar a mujeres hondureñas empleadas en ocupaciones domésticas en Estados Unidos. Para ello, se utilizan encuestas aplicadas a mujeres hondureñas que viven en cinco estados del país norteamericano y se emplea estadística descriptiva e inferencial. Adicionalmente, se usa una regresión logística para analizar los determinantes de la participación en empleos domésticos. Cuando se compara con todas las otras ocupaciones, las mujeres hondureñas que trabajan en este rubro presentan diferencias en edad, número de dependientes, posesión de bienes, ahorros y posesión de cuenta bancaria. Similarmente, el análisis de determinantes muestra las variables significativas que incluyen edad (95 % IC 0,92-2,63 p= 0,94), ahorros (95 % IC 0,01-0,97, p= 0,047), cuenta bancaria (95 % IC 0,88-71,05, p= 0,064), ingreso mensual (95 % IC 0,99-1,00, p= 0,096) y seguro social (95 % IC 0,02-1,29 p= 0,086). Promover la adopción de instrumentos de derecho internacional puede ser una alternativa para fomentar los derechos humanos de esta población. El artículo termina mostrando líneas de investigación sobre migración para mujeres hondureñas y centroamericanas viviendo en Estados Unidos.

Effect of education on the risk of gender-based violence in the Philippines

Background@#Gender-based violence originates when societal gender-based expectations and the reality are not consistent. One such example is: there has been a recent rise in women's education in the Philippines, yet the prevalence of traditional female role expectations in the context of the heavily Catholic Filipino society remains unchanged. @*Objectives@#In this paper, the relationship between women's education and their risk of gender-based violence (GBV) is examined and compared with the relationship between the education of their partners and the women's risk of experiencing GBV. @*Methodology@#Our sample included women living in the Philippines surveyed by the Demographic Health Survey in 2017. We used multivariate logistic regression on the respondents' and the partner's education level, with respondent's risk of experiencing GBV. @*Results@#We found that there was a slight but statistically significant decreased risk of GBV experience with increased years of education of both the female respondents and their male partners. For all female respondents, there was a 3.7% decrease in the risk of GBV per additional year of their own education. For those with partners, there was a 2.3% decrease in the risk of GBV per additional year of their partner's education. @*Conclusion@#We found that the education of male partners is as much of a factor as the women's own education in her likelihood of experiencing violence. From this, we established that partner selection based on their education levels may act as a protective factor for an individual's likelihood of experiencing GBV. Policy initiatives should address increasing male awareness of safe behavior and violence against women, especially while traditional gender roles are still predominant in the Filipino society.

Evaluation of key survey components of bio-behavioral surveillance among HIV high-risk subpopulation in Western India

Background: High-quality data are of prime importance in any health survey because survey data are considered as a gold standard for nationally representative data. The quality of data collection largely depends on the design of the questionnaire, training, and skills of the interviewer. Objectives: In the present study, we tried to evaluate three key components, such as questionnaire design, human resource and training of the field staff for Integrated Biological and Behavioural Surveillance carried out among the HIV high-risk subpopulation. Methods: A mixed-methods approach was used. Qualitative and quantitative data collection was carried out in the year 2015 with cross-sectional survey design in western states of India. The in-depth interviews of 10 stakeholders, structured interviews of the survey respondents (n = 560), and field investigators (n = 71) were conducted. Data triangulation was used to find out the concurrence of the qualitative and quantitative data. Results: Comprehensive and standardized survey questionnaire, structured training agenda, and strategic preparation for recruiting human resources were the overall strengths of the survey. However, during the implementation of the survey, there were some difficulties reported in data collection process. Overall, the respondents and investigators felt that the questionnaire was long and exhaustive. Difficulties were faced while collecting data on sexual history. The field staffs were not adequately experienced to work with sensitive population. Conclusions: In order to have accurate, reliable data, especially on sexual behavior; emphasis should be given on simple questionnaire with the use of community-friendly language, skilled and experienced interviewers for data collection, and extensive field training.

Survey Data on Perceptions of Contraceptive Methods as Compositional Tables / Datos de encuesta sobre percepciones de medidas contraceptivas como tablas composicionales

Abstract This paper studies the relative evaluation of young people and the possible benefits associated with three methods of avoiding sexually transmitted infections/AIDS and/or unwanted pregnancies (condoms, contraceptive pills, morning-after pills). A survey evaluating these three methods, with respect to ten different items, was given to 145 undergraduate students (76% females, 24% males). Results show that, compared to pills, condoms are positively valued as protection against sexually transmitted infections/AIDS, couples are interested in using them to protect their health, and they are appreciated for their lack of side effects. Pills are better valued than condoms with respect to feelings of pleasure for both sexes and not as valued in preventing sexually transmitted infections. Females' assessments are less extreme than male's for five of the six items, but are more pronounced with respect to the assumption that using condoms shows an interest in the couple taking care of their sexual health. The study shows a general preference towards condoms rather than contraceptive pills and postcoital pills, but men are far more likely to choose this option. The conclusions are based on a compositional analysis of two way tables.

Resumen Este trabajo estudia la percepción relativa de los jóvenes de los posibles beneficios asociados a tres métodos para evitar infecciones de transmisión sexual/SIDA y/o embarazos no deseados (condones, píldoras anticonceptivas, píldoras poscoitales o del día después). Al efecto de evaluar estos tres métodos se pasó una encuesta a 145 estudiantes de pregrado (76% mujeres, 24% hombres) con respecto a diez ítems diferentes. Los resultados muestran que, en comparación con las píldoras, los condones se valoran positivamente como protección contra infecciones de transmisión sexual/SIDA, las parejas están interesadas en utilizarlas para proteger su salud, y son apreciados por su falta de efectos secundarios. Las dos píldoras están mejor valoradas que los condones con respecto a los sentimientos de placer para ambos sexos y no tan valoradas en la prevención de infecciones de transmisión sexual. Las evaluaciones de las mujeres son menos extremas que las de los hombres en cinco de los seis ítems, pero son más pronunciadas con respecto a la suposición de que el uso de condones muestra un interés por la pareja cuidando su salud sexual. El estudio muestra una preferencia general hacia los condones en lugar de las píldoras anticonceptivas y las píldoras poscoitales, pero es mucho más probable que los hombres elijan esta opción. Las conclusiones se basan en un análisis composicional de tablas de doble entrada.

Weighted estimation methods for multistage sampling survey data / 中华流行病学杂志

Multistage sampling techniques are widely applied in the cross-sectional study of epidemiology, while methods based on independent assumption are still used to analyze such complex survey data. This paper aims to introduce the application of weighted estimation methods for the complex survey data. A brief overview of basic theory is described, and then a practical analysis is illustrated to apply to the weighted estimation algorithm in a stratified two-stage clustered sampling data. For multistage sampling survey data, weighted estimation method can be used to obtain unbiased point estimation and more reasonable variance estimation, and so make proper statistical inference by correcting the clustering, stratification and unequal probability effects.

Ready-to-eat Cereal Consumption Enhances Milk and Calcium Intake in Korean Population from 2001 Korean National Health and Nutrition Survey

The purpose of this study was to establish an association between the consumption of ready-to-eat cereal (RTEC), milk, and calcium within the context of the most current population dietary practice in Korea. Inadequate calcium intake among Korean children and adults is one of the important public health concern. Milk is one of the best calcium sources because of its bioavailability, and RTEC is one of the foods commonly consumed with milk. The most recent Korean National Health and Nutrition Survey, 2001 dataset was used as the source of data for this research. Subjects excluding pregnant women, were categorized according to gender and age (1~5, 6~11, 12~19, 20~49, 50 + years) and then by consumption of RTEC and milk. SAS and SUDAAN were used for statistical analyses. Sample weighted means, standard errors, and population percentages were calculated, and multiple regression model with adjustment for covariates were used to determine the predictability of total daily calcium intake from inclusion of RTEC and milk compared to the meal without RTEC and milk. RTEC was consumed by 2.4% of Korean people. Average calcium intake was 17 times greater when RTEC was consumed with milk than when RTEC was consumed without milk. Respondents who consumed RTEC with milk had significantly higher mean daily calcium and other nutrient intakes than respondents who consumed neither. In the multiple regression analysis, milk consumption with or without RTEC predicted total daily calcium intake after adjusting for age, income, and alcohol consumption (p < 0.0001). The percentage of respondents below the estimated average requirement (EAR) level for calcium was lower for RTEC consumers than for RTEC non-consumers in all age-gender groups, especially significant differences were in children aged 1~5, boys and girls aged 12~19, men aged 20~49, and women older than 50 years of age. RTEC consumption was not associated with intake in excess of the tolerable upper intake level (UL) for calcium. In conclusion, RTEC consumption was positively associated with both milk and calcium intakes in all age and gender groups in Korean population.
