To assess knowledge, risk perception and behaviours of a sample of swimming pool users in Palermo. A total of 498 subjects were interviewed by self-administered anonymous questionnaire including socio-demographic questions, knowledge/risk perception and behaviours. Overall, 289 subjects (58%) had a mean of 1.9 ± 1.2 healthy behaviours. Age older than 30 years (OR=0.46; 95% CI=0.26-0.81), female...

(where a, , , , = a _ , = 0). Suppose that [possibly after replacement of f ( s ) by f ( s ) l either a,, > 0 for i = 0, 1,. . . , n or a , > 0 , a,, > 0 and a, , , , > 0 for i = 0, 1,. . . , n 1. Then if any of f ( s ) , f , (s) and f,(s) has all zeros in Re[sl < 0, the other two polynomials have this property. In this work, we shall indicate how a parallel result can be obtained for discrete-...

The objective of this study was to investigate the frequency of HIV infection among female sex workers in the port area of Imbituba (State of Santa Catarina), and to identify the viral subtype and its susceptibility to antiretroviral medications. Ninety women were interviewed between December 2003 and February 2004. Six (6.7%) were HIV-positive. Genotyping for HIV, performed on four samples, de...

Main results 10.3% of participants were depressed at follow up. Multiple disadvantages in early life were associated with depression (odds ratio [OR] 5.1, 95% CI 2.1 to 12.0). More women than men had depression (OR 2.7, CI 1.1 to 6.3). Types of disadvantages that were associated with depression were social dependence and overcrowding (OR 5.1, CI 2.1 to 12.0), poor physical care and poor motheri...

BACKGROUND Factors associated with depression are usually identified from cross-sectional studies. AIMS We explore the relative roles of onset and recovery in determining these associations. METHOD Hazard ratios for onset and recovery were estimated for 39 risk factors from a cohort study of 10,045 general practice attendees whose depression status was assessed at baseline, 6 and 12 months....

OBJECTIVE To determine prevalence of HIV infection in a cohort of female sex workers in Cameroon, and to describe characteristics associated with HIV infection in this population. METHODS In a cross sectional study, 2260 female sex workers in Cameroon were interviewed and screened for HIV serostatus. A standardised questionnaire was used to collect information on sociodemographic characterist...

Because few prospective studies have examined the independent influence of mothers and fathers on smoking experimentation, we tested the association between a set of parent-specific, familial and peer interactions with smoking experimentation in early adolescence. Data come from two cohorts in the British Youth Panel Survey (N = 1736; mean age at baseline, 11.26; SD = 0.65), a study of children...

This meta-analysis investigates gender differences in economic negotiation outcomes. As suggested by role congruity theory, we assume that the behaviors that increase economic negotiation outcomes are more congruent with the male as compared with the female gender role, thereby presenting challenges for women's negotiation performance and reducing their outcomes. Importantly, this main effect i...

Caregivers represent an important source of care for older adults. Many studies focused on the negative aspects of elder caregiving but few studies have analyzed also the positive effects. In addition, no studies have considered contemporarily the positive and the negative impact of caregiving to elderly people on the same people using a structural equation modeling. The purpose of this study ...

This paper describes the findings from a 10-month ethnographic study of the female sex industry in a large British city. I argue that sex workers construct a continuum of risk which prioritizes certain types of dangers depending on the perceived consequences and the degree of control individuals consider they have over minimising the likelihood of a risk occurring. Although health-related matte...
