Multimorbidity patterns and associated factors in a megacity
OBJECTIVE: To identify empirical patterns of multimorbidity and quantify their associations with socioeconomic, behavioral characteristics, and health outcomes in the megacity of São Paulo. METHODS: This was a cross-sectional study conducted through household interviews with residents aged 20 years or older in urban areas (n = 3,184). Latent class analysis was used to identify patterns among the co-existence of 22 health conditions. Age-adjusted …
Urban Rail Transportation and Sars-Cov-2 Infections
Introduction: The large number of passengers, limited space and shared surfaces can transform public transportation into a hub of epidemic spread. This study was conducted to investigate whether proximity to railway stations, a proxy for utilization, was associated with higher rates of SARS-CoV-2 infection across small-areas of the Lisbon Metropolitan Area (Portugal). Methods: The number of SARS-CoV-2 confirmed infections from March 2 until July …
A Case-Control Study of Contextual Factors for Sars-CoV-2 Transmission
Background: Knowledge on the settings and activities associated with a higher risk of SARS-CoV-2 transmission is essential to inform decision-making. We thus designed a case-control study to identify relevant settings for community transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Portugal. Methods: We evaluated 1,088 cases, identified through the national surveillance system, and 787 community controls, recruited us…
HIV testing practices as reported by HIV-infected patients in four European countries
HIV testing constitutes an important strategy to control the HIV epidemic, which therefore merits an observation of HIV testing practices to help improve testing effectiveness. In 2008, a cross-sectional survey among recently diagnosed (≤ 3 years) HIV-infected patients was conducted in Belgium, Estonia, Finland and Portugal. Participants were questioned about reasons for HIV testing, testing place and testing conditions. Univariate and multivaria…
Associations between a priori -defined dietary patterns and longitudinal changes in bone mineral density in adolescents
Objective To quantify short- and long-term associations between dietary patterns defined a priori and bone mineral density (BMD) during adolescence. Design Dietary patterns were defined at 13 years old using a Mediterranean diet (MD) quality index, the Dietary Approaches to Stop Hypertension (DASH) diet index and the Oslo Health Study (OHS) dietary index. Linear regression coefficients were used to estimate associations between dietary patterns a…
O5-2.4 Low-grade systemic inflammation in early adolescence predicts suboptimal bone quality in late adolescence
Introduction Early inflammatory changes may explain the negative impact of adiposity on bone acquisition during childhood. We aimed at estimating the effect of systemic inflammation during adolescence on forearm bone mineral density at 17 years-old. Methods We used data from 377 girls born in 1990 and assessed at 13 and 17 years-old (EPITeen cohort). Adolescents were evaluated through physical examination, including height, weight and bone minera…
P2-162 Bone accrual at the forearm during adolescence
Introduction Whether bone quality is essentially modifiable or tracks predictably up to adulthood is unclear. We aimed to identify a biological timing when interventions may have optimal impact on future bone properties. Methods Participants were 709 girls from a cohort of adolescents born in 1990 and evaluated at 13 and 17 years-old. Evaluations consisted of structured questionnaires including gynaecologic age (GA) and physical evaluations compr…
P2-199 Association between adherence to the mediterranean diet and bone quality in a sample of Portuguese adolescents
Introduction Dietary patterns provide insights into how diet, rather than specific nutrients, affects bone health. We aimed to evaluate whether Mediterranean diet associates with bone mineral density at 13 years-old. Methods We used data from 1232 adolescents (44.7% males) born in 1990 and assessed at 13 years-old (EPITeen cohort). Adolescents were evaluated through physical examination, including height, weight and forearm bone mineral density (…
Syringe exchange in community pharmacies—The Portuguese experience
Avaliação da competitividade da agricultura do Alentejo no âmbito do ecossistema montado
Neste estudo procede-se à avaliação sócioeconómica do ecossistema montado no Alentejo, em termos da viabilidade dos actuais sistemas de produção e dos efeitos da política agrícola na sua competitividade e sustentabilidade. A metodologia utilizada baseou-se na construção de matrizes de análise política. Em função dos níveis de rendimento e dos efeitos das medidas de política agrícola, os sistemas de produção são classificados em termos da sua cont…
Patterns in the use of medicines by university students in Maputo, Mozambique
Patterns in the use of medicines are expected to reflect distinct health features between populations. This study aimed to describe the self-reported use of medication by a sample of university students in Maputo, Mozambique. We conducted a survey of 797 students in a private university in Maputo. Participants completed a questionnaire including socio-demographic data and pattern of medication use in the preceding month. Information was collected…

Minetown, Milltown, Railtown
Minetown, Milltown, Railtown explores deeply and broadly the links between economic resources, industrial structure, and social patterns in Canada. It is a study of the six hundred or so communities from coast to coast, each of which was created and is dominated by a single Industrial firm.
