RESUMO

Purpose: To examine associations of prenatal biomarkers of pesticide exposure with birth size measures and length of gestation among newborns from the Infants' Environmental Health (ISA) birth cohort, Costa Rica. Methods: We included 386 singleton liveborn newborns with data on birth size measures, length of gestation, and maternal urinary biomarkers of chlorpyrifos, synthetic pyrethroids, mancozeb, pyrimethanil, and 2, 4-D during pregnancy. We associated biomarkers of exposure with birth outcomes using multivariate linear regression and generalized additive models. Results: Concentrations were highest for ethylene thiourea (ETU, metabolite of mancozeb), median = 3.40; p10-90 = 1.90-6.79 µg/L, followed by 3,5,6-trichloro-2-pyridinol (TCP, metabolite of chlorpyrifos) p50 = 1.76 p10-90 = 0.97-4.36 µg/L, and lowest for 2,4-D (p50 = 0.33 p10-90 = 0.18-1.07 µg/L). Among term newborns (≥37 weeks), higher prenatal TCP was associated with lower birth weight and smaller head circumference (e.g., ß per 10-fold-increase) during the second half of pregnancy = -129.6 (95% confidence interval [CI] = -255.8, -3.5) grams, and -0.61 (95% CI = -1.05, -0.17) centimeters, respectively. Also, among term newborns, prenatal 2,4-D was associated with lower birth weight (ß per 10-fold-increase = -125.1; 95% CI = -228.8, -21.5), smaller head circumference (ß = -0.41; 95% CI = -0.78, -0.03), and, during the second half of pregnancy, with shorter body length (ß = -0.58; 95% CI = -1.09, -0.07). Furthermore, ETU was nonlinearly associated with head circumference during the second half of pregnancy. Biomarkers of pyrethroids and pyrimethanil were not associated with birth size, and none of the biomarkers explained the length of gestation. Conclusions: Prenatal exposure to chlorpyrifos and 2,4-D, and, possibly, mancozeb/ETU, may impair fetal growth.

RESUMO

Metagenomic analysis typically includes read-based taxonomic profiling, assembly, and binning of metagenome-assembled genomes (MAGs). Here we integrate these steps in Read Annotation Tool (RAT), which uses robust taxonomic signals from MAGs and contigs to enhance read annotation. RAT reconstructs taxonomic profiles with high precision and sensitivity, outperforming other state-of-the-art tools. In high-diversity groundwater samples, RAT annotates a large fraction of the metagenomic reads, calling novel taxa at the appropriate, sometimes high taxonomic ranks. Thus, RAT integrative profiling provides an accurate and comprehensive view of the microbiome from shotgun metagenomics data. The package of Contig Annotation Tool (CAT), Bin Annotation Tool (BAT), and RAT is available at https://github.com/MGXlab/CAT_pack (from CAT pack v6.0). The CAT pack now also supports Genome Taxonomy Database (GTDB) annotations.

RESUMO

Members of the Equus genus exhibit a fascinating capacity for hybridization, giving rise to healthy offspring. Mules, resulting from the mating of a mare with a jack, represent the most prevalent equid hybrid, serving diverse roles in our society. While in vitro embryo production, particularly through Intracytoplasmic Sperm Injection (ICSI), has rapidly gained significance in domestic horses, the in vitro production in other equids remains largely unexplored. Utilizing donkey sperm for fertilizing horse oocytes not only addresses this gap but also provides an opportunity to investigate donkey sperm's fertilization capability in vitro to further improve donkey ICSI. In this work, we initially studied the localization of donkey sperm Phospholipase C zeta (PLCζ) and assessed the sperm's capacity to induce pronuclear formation and maternal SMARCA4 recruitment upon injection into pig oocytes through ICSI. Subsequently, we investigated the injection of donkey sperm into horse oocytes, evaluating in vitro production up to the blastocyst stage using sperm from different jacks, including frozen and refrigerated samples. Distinct patterns of PLCζ localization were observed for donkey sperm cells compared to their horse counterparts. Additionally, donkey sperm exhibits a reduced ability to induce porcine oocyte activation. However, when injected into horse oocytes, donkey sperm demonstrated sufficient capability to induce oocyte activation as no discernible differences in cleavage or blastocyst rates are observed between in vitro produced mules and horse ICSI embryos. Our study not only delineates PLCζ localization in donkey sperm but also suggests potential differences in the ability to induce oocyte activation in pigs compared to horses while observing no distinctions in pronuclear recruitment of SMARCA4. Interestingly, donkey sperm remains sufficiently capable of inducing horse oocyte activation for in vitro mule blastocyst production.

RESUMO

Groundwater is the most important source for drinking water in The Netherlands. Groundwater quality is threatened by the presence of pesticides, and biodegradation is a natural process that can contribute to pesticide removal. Groundwater conditions are oligotrophic and thus biodegradation can be limited by the presence and development of microbial communities capable of biodegrading pesticides. For that reason, bioremediation technologies such as bioaugmentation (BA) can help to enhance pesticide biodegradation. We studied the effect of BA using enriched mixed inocula in two column bioreactors that simulate groundwater systems at naturally occurring redox conditions (iron and sulfate-reducing conditions). Columns were operated for around 800 days, and two BA inoculations (BA1 and BA2) were conducted in each column. Inocula were enriched from different wastewater treatment plants (WWTPs) under different redox-conditions. We observed a temporary effect of BA1, reaching 100% removal efficiency of the pesticide 2,4-D after 100 days in both columns. In the iron-reducing column, 2,4-D removal was in general higher than under sulfate-reducing conditions demonstrating the influence of redox conditions on overall biodegradation. We observed a temporary shift in microbial communities after BA1 that is relatable to the increase in 2,4-D removal efficiency. After BA2 under sulfate-reducing conditions, 2,4-D removal efficiency decreased, but no change in the column microbial communities was observed. The present study demonstrates that BA with a mixed inoculum can be a valuable technique for improving biodegradation in anoxic groundwater systems at different redox-conditions.

RESUMO

Resumo Objetivo Desenvolver e realizar a validação de conteúdo de um instrumento de autoavaliação da qualidade do cuidado em Instituições de Longa Permanência para Idosos (ILPI), denominado QualificaILPI. Método Estudo metodológico realizado entre março e dezembro de 2021. O instrumento foi desenvolvido com base em modelo multidimensional de qualidade, legislação brasileira e pesquisa bibliográfica e contém padrões de qualidade para autoavaliação das ILPI nas dimensões: ambiente, lar, cuidado, envolvimento familiar e da comunidade, equipe de trabalho e gestão. Cada padrão é descrito e seguido por uma escala, com parâmetros para classificar o nível de qualidade da ILPI em incipiente, intermediário, consolidado. A Técnica Delphi modificada foi empregada para validação por um comitê de 10 especialistas quanto a pertinência do padrão para avaliação da qualidade da ILPI, da adequação dos objetivos e da escala de avaliação, clareza, podendo fazer comentários. O padrão foi mantido quando houve 75% de concordância entre os especialistas. O instrumento foi também avaliado pelo público-alvo, constituído por coordenadores de 10 ILPI, selecionadas por conveniência. Resultados No primeiro ciclo de avaliação, foram excluídos três padrões e dois novos foram criados. No segundo, alterou-se a dimensão de um padrão e dois padrões foram unidos. Ao final, permaneceram 29 padrões divididos em seis dimensões. O público-alvo, gestores de ILPI, sugeriu alterações na redação de alguns padrões. Houve consenso de 80% ou superior em todos os padrões. Conclusão O QualificaILPI poderá contribuir para o monitoramento das ILPI favorecendo a melhoria do cuidado ofertado aos residentes.


Abstract Objective To develop and validate the content of a self-assessment instrument for the quality of care in Long-Term Care Facilities for Older Adults (Instituições de Longa Permanência para Idosos - ILPIs), named QualificaILPI. Method A methodological study conducted between March and December 2021. The instrument was developed based on a multidimensional quality model, Brazilian legislation, and literature research. It contains quality standards for self-assessment of ILPIs in the dimensions of environment, home, care, family and community involvement, work team, and management. Each standard is described and followed by a scale with parameters to classify the level of ILPI quality as incipient, intermediate, or consolidated. The modified Delphi Technique was employed for validation by a committee of 10 experts regarding the relevance of the standard for ILPI quality assessment, the appropriateness of objectives, the evaluation scale, and clarity, allowing for comments. The standard was retained when there was 75% agreement among the experts. The instrument was also evaluated by the target audience, consisting of coordinators from 10 ILPIs selected for convenience. Results In the first assessment cycle, three standards were excluded, and two new ones were created. In the second cycle, the dimension of one standard was changed, and two standards were combined. In the end, 29 standards remained, divided into six dimensions. The target audience, ILPI managers, suggested changes in the wording of some standards. There was a consensus of 80% or higher for all standards. Conclusion QualificaILPI has the potential to contribute to monitoring ILPIs, promoting the improvement of care offered to residents.

RESUMO

BTEX (benzene, toluene, ethylbenzene, xylene) are common pollutants often found in former gasworks sites together with some other contaminants like indene, indane and naphthalene (Ie, Ia, N). This study aimed to evaluate the inhibitory or stimulative substrate interactions between BTEX, and Ie, Ia, N during aerobic biodegradation. For this, batch bottles, containing originally anaerobic subsurface sediments, groundwater and indigenous microorganisms from a contaminated former gasworks site, were spiked with various substrate combinations (BTEX, BTEXIe, BTEXIa, BTEXN, BTEXIeIa, BTEXIeN, BTEXIaN, BTEXIeIaN). Subsequently concentrations were monitored over time. For the BTEXIeIaN mixture, initial concentrations were between 1 and 5 mg L-1, and all compounds were completely degraded by the microbial consortia within 39 days of incubation. The experimental data were fitted to a first order kinetic degradation model for interpretation of inhibition/stimulation between the compounds. Results showed that indene, indane, and naphthalene inhibited the degradation of benzene, toluene, ethylbenzene, o-xylene, with benzene being the most affected. M/p-xylene is the only compound whose biodegradation is stimulated by the presence of indene and indane (individually or mixed) but inhibited by the presence of naphthalene. 16S rRNA amplicon sequencing revealed differentiation in the microbial communities within the batches with different substrate mixtures, especially within the two microbial groups Micrococcaceae and Commamonaceae. Indene had more effect on the BTEX microbial community than indane or naphthalene and the presence of indene increased the relative abundance of Micrococcaceae family. In conclusion, co-presence of various pollutants leads to differentiation in degradation processes as well as in microbial community development. This sheds some light on the underlying reasons for that organic compounds present in mixtures in the subsurface of former gasworks sites are either recalcitrant or subjective towards biodegradation, and this understanding helps to further improve the bioremediation of such sites.

RESUMO

This article aims to evaluate the Brazilian Long-Term Institutions for Older People (LTIE), according to the Integrated Multidimensional Theoretical Model of Quality and Service (MIQA), and compare the performance achieved between the regions of the country. Descriptive ecological study carried out with public secondary data from the LTIE participating in the 2018 Census of the Unified Social Assistance System. An Evaluation Matrix was constructed from the Census variables and the MIQA Theoretical Model. Quality parameters were used to classify the institutions' performance for each indicator as "incipient", "developing" or "desirable". The disparity index was obtained for each indicator. 1,665 institutions were analyzed. Differences were observed in the percentages of LTIE with "desirable" performance between Brazilian regions, and the need for improvement in most LTIE in relation to the proportion of caregivers of older people, the composition of the multidisciplinary team, accessibility and supply of health promotion actions. There was a need for government support for the suppression of exclusionary differentiation criteria and for the expansion of services to overcome overcrowding.

RESUMO

BACKGROUND: Fractional exhaled nitric oxide (FeNO) is a marker of airway inflammation. Elevated FeNO has been associated with environmental exposures, however, studies from tropical countries are limited. Using data from the Infants' Environmental Health Study (ISA) birth cohort, we evaluated medical conditions and environmental exposures' association with elevated FeNO. METHODS: We performed a cross-sectional analysis of 277 women and 293 8-year old children who participated in the 8-year post-partum visit in 2019. We measured FeNO and collected information on medical conditions and environmental exposures including smoke from waste burning, work in banana plantations, and home pesticide use. We defined elevated FeNO as >25 ppb for women and >20 ppb for children. To evaluate factors associated with elevated FeNO, we used logistic regression models adjusted for obesity in women and unadjusted in children. RESULTS: Overall elevated FeNO was common (20% of women, 13% of children). Rhinitis diagnosis was significantly associated with elevated FeNO in both women (odds ratio (OR): 3.67 95% Confidence Interval (CI): 1.81,7.35) and children (OR: 8.18 95%CI: 3.15, 21.22); wheeze was associated with elevated FeNO in women (OR: 4.50 95% CI: 2.25, 8.99). Environmental exposures were associated with elevated FeNO, but not significantly. Waste burning was associated with elevated FeNO in both women (OR: 1.58 95%CI 0.68, 4.15) and children (OR: 2.49 95%CI:0.82, 10.79). Para-occupational pesticide exposures were associated with elevated FeNO in women and children. For women, having a partner working in agriculture was associated with elevated FeNO (OR: 1.61 95%CI:0.77, 3.58) and for children, maternal work in agriculture was associated with elevated FeNO. (OR 2.08 95%CI 0.86, 4.67) CONCLUSION: Rhinitis and wheeze were associated with elevated FeNO in this rural, agricultural population. Smoke from waste burning as well as para-occupational pesticide exposure may contribute to elevated FeNO in rural communities.

RESUMO

El Síndrome de Edwards o trisomía 18 es un trastorno cromosómico autosómico que se caracteriza por la presencia de un cromosoma 18 extra, completo, parcial o en mosaico. La prevalencia de esta trisomía en recién nacidos se calcula entre 1 en 6000 a 1 en 8000, siendo la segunda alteración cromosómica autosómica en frecuencia después de la trisomía 21. Se describe un caso de trisomía 18 valorada ecográficamente y confirma por estudio genético. Se trata de una paciente de 26 años de edad primigesta, a la que se realiza estudio ecográfico de screening de cromosomopatías, donde se evidencia ausencia de hueso nasal, quiste de cordón umbilical, ante el riesgo moderado para trisomía 21 se realiza DNA fetal en sangre materna, con resultado de trisomía 18, razón por la cual se decide la interrupción del embarazo por mal pronóstico fetal. Se revisaron aspectos de la frecuencia etiología, diagnóstico y pronóstico de la trisomía 18.

RESUMO

An animal's daily use of time (their "diel activity") reflects their adaptations, requirements, and interactions, yet we know little about the underlying processes governing diel activity within and among communities. Here we examine whether community-level activity patterns differ among biogeographic regions, and explore the roles of top-down versus bottom-up processes and thermoregulatory constraints. Using data from systematic camera-trap networks in 16 protected forests across the tropics, we examine the relationships of mammals' diel activity to body mass and trophic guild. Also, we assess the activity relationships within and among guilds. Apart from Neotropical insectivores, guilds exhibited consistent cross-regional activity in relation to body mass. Results indicate that thermoregulation constrains herbivore and insectivore activity (e.g., larger Afrotropical herbivores are ~7 times more likely to be nocturnal than smaller herbivores), while bottom-up processes constrain the activity of carnivores in relation to herbivores, and top-down processes constrain the activity of small omnivores and insectivores in relation to large carnivores' activity. Overall, diel activity of tropical mammal communities appears shaped by similar processes and constraints among regions reflecting body mass and trophic guilds.

RESUMO

RESUMO O Programa Saúde na Escola tem como meta a construção de escolas saudáveis. Estudo de caso, de abordagem qualitativa com intenção de identificar e compreender como se comportam, no esforço de integração, profissionais envolvidos no Programa Saúde na Escola, a partir de sua inserção nas atividades preconizadas. Após construção do modelo lógico do programa, foi realizado consenso com experts para elaboração de matriz de indicadores, originando roteiro semiestruturado. Foram realizadas 25 entrevistas, nas Unidades Básicas de Saúde e Escolas de Ensino Fundamental, além das Gerências Regionais da Saúde e da Educação. As práticas foram consideradas multissetoriais, sem soma de esforços e coparticipação efetiva, sendo planejadas por um único setor ou profissional; os gaps existentes são reconhecidos tanto quanto a importância do programa; as práticas acontecem com baixo vínculo entre equipes. A forma fragmentada de perceber os problemas dos escolares dificulta essa integração.


ABSTRACT The School Health Program aims to build healthy schools. This qualitative case study aimed to identify and understand how professionals involved in the School Health Program behave in the integration based on their inclusion in the recommended activities. The consensus was reached with experts to develop a matrix of indicators after building the Program's logical model, resulting in a semi-structured roadmap. Twenty-five interviews were held in the Basic Health Units, Elementary Schools, and the Regional Health and Education Administrations. The practices were multisectoral, with no combined efforts and effective co-participation, planned by a single sector or professional, the existing gaps are recognized as much as the importance of the program, and the practices are implemented with a low bond between teams. The fragmented perception of students' problems hinders this integration.

RESUMO

Pesticides application on agricultural fields results in pesticides being released into the environment, reaching soil, surface water and groundwater. Pesticides fate and transformation in the environment depend on environmental conditions as well as physical, chemical and biological degradation processes. Monitoring pesticides biodegradation in the environment is challenging, considering that traditional indicators, such as changes in pesticides concentration or identification of pesticide metabolites, are not suitable for many pesticides in anaerobic environments. Furthermore, those indicators cannot distinguish between biotic and abiotic pesticide degradation processes. For that reason, the use of molecular tools is important to monitor pesticide biodegradation-related genes or microorganisms in the environment. The development of targeted molecular (e.g., qPCR) tools, although laborious, allowed biodegradation monitoring by targeting the presence and expression of known catabolic genes of popular pesticides. Explorative molecular tools (i.e., metagenomics & metatranscriptomics), while requiring extensive data analysis, proved to have potential for screening the biodegradation potential and activity of more than one compound at the time. The application of molecular tools developed in laboratory and validated under controlled environments, face challenges when applied in the field due to the heterogeneity in pesticides distribution as well as natural environmental differences. However, for monitoring pesticides biodegradation in the field, the use of molecular tools combined with metadata is an important tool for understanding fate and transformation of the different pesticides present in the environment.

RESUMO

Resumo Avaliar por meio de uma revisão de escopo estudos que abordam a percepção e atitude do cirurgião-dentista diante do atendimento a mulheres em situação de violência. Utilizando os descritores women violence, dentist attendence ou dentist care, foram identificados 473 artigos, sendo incluídos 13, ao final da seleção. Embora a necessidade de capacitação tenha sido predominante, ela não é suficiente. Existe uma fragilidade em se compreender a violência como problema de saúde, de entender o papel do profissional na solução desse problema, os fatores que podem contribuir com seu crescimento ou seu controle. Os resultados revelaram que o cirurgião-dentista apresentou maior dificuldade do que os outros profissionais no enfrentamento e exigem um amplo aprendizado. O reconhecimento dos referidos casos pelo cirurgião-dentista exige a incorporação de medidas educativas que provoquem mudanças culturais, desconstrução de normas de gênero e a desnaturalização desse fenômeno social.


Abstract The purpose of this study was to evaluate, through a scope review, studies that address the perceptions and attitudes of dentists regarding the care of women in situations of violence. Using the descriptors women violence, dentist attendance or dentist care, 473 articles were identified, of which 13 were included at the end of the selection process. Although the need for training was predominant, it was not sufficient. There is a weakness in understanding violence as a health problem, in understanding the role of the professional in solving this problem, and the factors that can contribute to its growth or its control. The results revealed that the dentist had greater difficulty than other professionals in coping with the issue and required extensive training. The recognition of these cases of abuse by the dentist requires the incorporation of educational measures that cause cultural changes, deconstruction of gender norms and the denaturalization of this social phenomenon.

Avaliar por meio de uma revisão de escopo estudos que abordam a percepção e atitude do cirurgião-dentista diante do atendimento a mulheres em situação de violência. Utilizando os descritores women violence, dentist attendence ou dentist care, foram identificados 473 artigos, sendo incluídos 13, ao final da seleção. Embora a necessidade de capacitação tenha sido predominante, ela não é suficiente. Existe uma fragilidade em se compreender a violência como problema de saúde, de entender o papel do profissional na solução desse problema, os fatores que podem contribuir com seu crescimento ou seu controle. Os resultados revelaram que o cirurgião-dentista apresentou maior dificuldade do que os outros profissionais no enfrentamento e exigem um amplo aprendizado. O reconhecimento dos referidos casos pelo cirurgião-dentista exige a incorporação de medidas educativas que provoquem mudanças culturais, desconstrução de normas de gênero e a desnaturalização desse fenômeno social.

RESUMO

We produced and characterised biochar made from Caribbean pine sawdust as raw material. The biochar (BC500) was used as biocompatible support to co-inoculate phosphate solubilizing bacteria (PSB) (BC500/PSB) on Allium cepa L., plants at a greenhouse scale for four months. The three biomaterials study included proximate analysis, elemental analysis, aromaticity analysis, scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR), adsorption studies at different pH and PSB stability as a function of time. The results indicated that BC500 is suitable as organic support or solid matrix to maintain the viability of PSB able to solubilise P from phosphate rock (PR). The biofertilizer (BC500/PSB) allows increasing germination, seedling growth, nutrient assimilation, and growth of Allium cepa L., because PSB immobilised on BC500 promoted nutrient mobilisation, particularly P, during cultivation of Allium cepa L., at pots scale. The two treatments to evaluate the biofertilizer (BC500/PSB) showed the highest concentrations of total P with 1.25 ± 0.13 and 1.38 ± 0.14 mg bulb-1 in A. cepa L. This work presents the benefits of a new product based on bacteria naturally associated with onion and an organic material (BC500) serving as a bacterial carrier that increases the adsorption area of highly reactive nutrients, reducing their leaching or precipitation with other nutrients and fixation to the solid matrix of the soil.

RESUMO

Introduction: Playful learning for environmental education represents a participatory pedagogical mediation that considers the socio-environmental realities in which persons are immersed. Objective: To promote environmental education, through playful, participatory, and flexible methods, to prevent pesticide exposure. Methodology: Using geographic information systems, the distances between schools and bananas plantations were calculated. A playful and constructivism methodology was designed for primary school students (6 - 8.5 years), and their legal guardians. Subsequently, 148 workshops were developed in 37 rural Costa Rican schools, in which 2757 children and 387 adults participated. Results: Thirty-eight percent (38 %) (n=14) of the schools were located at less than 100 meters from banana plantations. Playful communication generated a participatory environment, in which local needs were identified and collective knowledge was built about the effects of pesticide exposure on the environment and human health. Participants were able to identify the main preventive actions to reduce pesticide exposure. Conclusions: Playful, participatory, and flexible methodologies in environmental education facilitate the process of sensitizing first cycle primary school students and their parents from rural communities about the risks of exposure to pesticides. The methodology used can be easily adapted for application in other environmental science studies.

RESUMO

The structure of forest mammal communities appears surprisingly consistent across the continental tropics, presumably due to convergent evolution in similar environments. Whether such consistency extends to mammal occupancy, despite variation in species characteristics and context, remains unclear. Here we ask whether we can predict occupancy patterns and, if so, whether these relationships are consistent across biogeographic regions. Specifically, we assessed how mammal feeding guild, body mass and ecological specialization relate to occupancy in protected forests across the tropics. We used standardized camera-trap data (1002 camera-trap locations and 2-10 years of data) and a hierarchical Bayesian occupancy model. We found that occupancy varied by regions, and certain species characteristics explained much of this variation. Herbivores consistently had the highest occupancy. However, only in the Neotropics did we detect a significant effect of body mass on occupancy: large mammals had lowest occupancy. Importantly, habitat specialists generally had higher occupancy than generalists, though this was reversed in the Indo-Malayan sites. We conclude that habitat specialization is key for understanding variation in mammal occupancy across regions, and that habitat specialists often benefit more from protected areas, than do generalists. The contrasting examples seen in the Indo-Malayan region probably reflect distinct anthropogenic pressures.

RESUMO

Create and evaluate the psychometric properties of the Quality of Life in the Neighborhood Questionnaire for Children 8 to 10 years of Age (QoL-N-Kids 8-10). The present study was conducted in a medium-sized city in southeastern Brazil with children at four public schools and one private school. The study involved three phases: a) generation and validation of the content of the items through a qualitative study and expert panel (n = 8); b) face validity through a pilot study and interviews with children (n = 30); and c) application of the final version (n = 261) for the evaluation of internal consistency, temporal stability, construct validity and discriminant validity. All statistical tests applied during this step were interpreted considering a 5% significance level. Among the 56 items generated, 38 were maintained in the scale and submitted to face validation. In this phase, the children suggested the inclusion of an additional item, resulting in a measure with 39 items. The questionnaire was submitted to reliability tests (Cronbach's alpha) and exploratory factor analysis, leading to a questionnaire with 27 items distributed among five domains. The measures exhibited good internal consistency (Cronbach's alpha = 0.805) and good test-retest reliability (weighted Kappa = 0.305 to 0.724; intraclass correlation coefficient = 0.917). Regarding discriminant validity, differences between groups (p < 0.001) were found for sex, age, income and place of residence. The QoL-N-Kids 8-10 instrument exhibited satisfactory psychometric properties and has potential for the assessment of neighborhood quality of life in children eight to ten years of age.
