Differences in health status, health behaviour and healthcare utilisation between Immigrant and native homeless people in Spain: An exploratory study
2021
Few studies have examined the differences between immigrant and native-born homeless populations. Our aim was to conduct an exploratory study to examine the differences in health status, health behaviour and healthcare utilisation in a sample of Spanish immigrant and native homeless people. Study was conducted in eight different temporary accommodations in the Valencia region in August 2018. Overall, 86 participants were included in the analysis who answered questionnaires concerning socio-demographic characteristics, immigration status, health status and behaviour, healthcare utilisation and experienced discrimination in healthcare and health literacy. In total, 76.7% were men with a mean …
Changes in At-Risk Behavior for HIV Infection among HIV-Positive Persons in Italy
2009
Many HIV-positive persons reportedly continue to engage in at-risk behavior. We compared the sexual and drug-using practices of HIV-positive persons before and after the diagnosis of HIV infection to determine whether their behavior had changed. To this end, in 2006, we conducted a cross-sectional study involving clinical centers in five Italian cities. Each center was asked to enroll 100 persons aged 18 years or older who had a diagnosis of HIV infection that dated back at least 2 years. Data were collected with a specifically designed questionnaire, administered during a structured interview. The McNemar chi2 test was used to compare the data before and after the diagnosis. A total of 497…
Use of alcohol, drugs, inhalants, and smoking tobacco and the long-term risk of depression in men: A nationwide Swedish cohort study from 1969–2017
2021
Background: The use of alcohol, drugs, inhalants, and smoking tobacco may lead to mood disorders such as depression. However, knowledge on the independent contributions of the use of these substances to the risk of depression is lacking. Methods: The study cohort consisted of 24,564 men included in the Swedish national military conscription register who were conscripted in 1969–1970 and followed until 2017. Cox proportional hazard ratios were used to estimate the risk of depression according to alcohol, drug, inhalant, and cigarette consumption, and adjusted for body mass index, verbal comprehension test scores, handgrip strength, and the other main exposures investigated. Results: During a…
Associations Between Trajectories of Leisure-Time Physical Activity and Television Viewing Time Across Adulthood: The Cardiovascular Risk in Young Fi…
2018
Background: The purpose of this study was to examine trajectories of leisure-time physical activity (LTPA) and television-viewing (TV) time and their associations in adults over 10 years. Methods: The sample comprised 2934 participants (men, 46.0%) aged 24–39 years in 2001 and they were followed up for 10 years. LTPA and TV time were assessed using self-report questionnaires in 2001, 2007, and 2011. Longitudinal LTPA and TV-time trajectories and their interactions were analyzed with mixture modeling. Results: Three LTPA (persistently highly active, 15.8%; persistently moderately active, 60.8%; and persistently low active, 23.5%) and 4 TV time (consistently low, 38.6%; consistently moderate,…
A CTLA4high genotype is associated with myasthenia gravis in thymoma patients
2005
Myasthenia gravis (MG) in thymoma patients depends critically on intratumorous generation and export of mature autoreactive CD4+ T cells. Why non-MG thymomas fail to produce CD4+ T cells is unknown. We studied three single-nucleotide polymorphisms of the cytotoxic T-lymphocyte–associated antigen 4(CTLA4) gene in thymoma patients, nonthymoma early-onset MG patients, and control subjects. Surprisingly, the CTLA4high genotype +49A/A, which is protective against several autoimmune diseases, exerted a prominent predisposing effect to paraneoplastic MG in thymoma patients. The unusual disease association with a CTLA4high genotype implies a unique pathogenesis of paraneoplastic MG, with high CTLA4…
Stability and prediction of physical activity in 5-, 10-, and 28-year follow-up studies among industrial employees.
2006
The aim of the study was to examine the stability of voluntary and household physical activity (PA) and to compare it with that of the use of the most common stimulants. The prospective cohort study comprised of follow-ups at 5, 10, and 28 years at baseline in 1973 in four plants of an industrial corporation in Finland. A systematic, non-proportional sample (n=902, age range 18-64 years) stratified for age, gender, and occupational status was drawn from the employees. Scores of PA were based on a questionnaire and interviews. Logistic regression models with proportional odds assumptions were counted. The 5-year stability (Spearman's rho) of PA time was 0.44 (PA intensity 0.44), the respecti…
Trends and Prevalence of Nocturia Among US Adults, 2005-2016
2019
Purpose: Increased nocturia episodes can be a clinical marker of poor health status. The present study aimed to evaluate patterns and temporal trends in nocturia and sociodemographic and lifestyle correlates in the US population. Methods: Participants, aged 20 years or older, were included in this repeated cross-sectional study. The National Health and Nutrition Examination Survey from 2005 to 2016 was used. Participants were asked “During the past 30 days, how many times per night did you most typically get up to urinate, from the time you went to bed at night until the time you got up in the morning?”. Individuals were categorized as either ≥ 1 nocturia episode or ≥ 2 nocturia episodes pe…
The Italian Multiple Sclerosis Database Network (MSDN): The risk of worsening according to IFNβ exposure in multiple sclerosis
2006
We evaluated the risk of worsening according to the length of exposure to interferon beta (IFNβ)ina large cohort of 2090 multiple sclerosis patients collected by the Italian MS Database Network. Overall 44-140 patient-visits with a follow-up of 22-143 patient-years were evaluated. Forty-one per cent of patients were exposed to IFNβ for up to 2 years, 39% for 2- 4 years and 20% for more than 4 years. A Cox regression model was used to analyse two clinical outcomes: disability progression and worsening of relapse rate. The technique of propensity score was applied to reduce bias in the comparison of non-randomized groups. The risks of disability progression (HR=0.23; 95% CI: 0.17 - 0.30) and …
Metric assessment of the "mastoid triangle" for sex determination: a validation study.
2006
Recently, a metric approach to skeletal sex determination was published by Paiva and Segre which is based on the summation of two triangular areas defined by three distinct craniometric landmarks: Porion, Mastoidale, and Asterion. According to the authors, values for the total triangle > or =1447.40 mm(2) are characteristic for male crania, while values < or =1260.36 mm(2) are indicative of female skulls (95% confidence). In order to evaluate the method's validity, two sex- and age-documented samples of different provenience were analyzed (N=197). The results show that while the indicated measurements display significant sex differences, the technique is of little practical meaning where a …
The psychometric properties of the Italian adaptation of the Health Orientation Scale (HOS)
2020
AbstractBackgroundA novel approach suggested that cognitive and dispositional features may explain in depth the health behaviors adoption and the adherence to prevention programs. The Health Orientation Scale (HOS) has been extensively used to map the adoption of health and unhealthy behaviors according to cognitive and dispositional features. Coherently, the main aim of the current research was to assess the factor structure of the Italian version of the HOS using exploratory and confirmatory factor analysis and testing the construct validity of the scale by assessing differences in health orientations between tobacco cigarette smokers and nonsmokers.MethodThe research protocol was organiz…
