This study examined tobacco use by tuberculosis (TB) patients through socio-health variables. The sample comprised 724 TB patients (mean age 37.1 years, SD = 11.3; males = 71.4%) receiving care from 40 primary health facilities across South Africa. They completed a questionnaire at baseline and also at a six-month follow-up. Multivariate logistic regression analysis using generalised estimation equation (GEE) modelling found that daily or almost daily tobacco use significantly reduced over time overall. In terms of socio-health variables, males and those with a comorbid chronic disease had had signficantly higher usage of tobacco over the observation period. 相似文献

The study assessed the prevalence of hazardous alcohol use among people living with HIV (PLHIV) and its correlates with socio-economic characteristics, disease variables and ART adherence in South Africa. The sample included 607 PLHIV (males =475, females =132; age range =18–61), sampled by all districts in the Eastern Cape. Participants were recruited through a health facility in the community through key informants or a support group. Results indicate that male PLHIV were more often than female PLHIV “past month” (18.9% vs. 6.1%) and hazardous alcohol drinkers (6.1% vs. 2.7%); using a cut-off score of 8 and more on the Alcohol Use Disorders Identification Test (AUDIT). Not having a disability grant for HIV/AIDS and the disability grant terminated were both related to past month alcohol use, while having the “disability grant stopped” was also related with hazardous or harmful drinking. Not having an AIDS diagnosis and not being on ART were both associated with past month alcohol use and hazardous or harmful drinking. CD4 counts and non-adherence to ART were both not significantly related with alcohol use status. Brief health provider initiated alcohol interventions for PLHIV should be promoted, with emphasis on targeting men. 相似文献

This study aimed to investigate contextual influences on condom use by South African university students. Twenty one-to-one, semi-structured interviews were conducted with male and female South African undergraduates. The data were thematically analysed. Results revealed that condom use was transient and often unrelated to disease prevention. Condom use was impeded by closer perceived intimacy, gender dynamics, and social stigma against proposing use of condoms in a presumably committed relationship. Public health policies regarding condom, pill and injection pricing / promotion, and religious toleration also hampered condom use, by encouraging a preference over hormonal contraception or proscribing contraceptive measures altogether. The results provide a basis for considering the impact of immediate and wider social contexts on condom use, as proposed by socio-ecological models of HIV risk behaviour. 相似文献

The aim of this study was to assess the prevalence and associated factors of problem drinking among South African youth (18–24 years). A cross-sectional population-based household survey was conducted using a multi-stage stratified cluster sampling approach. The total sample included 3123 participants (age range 18–24 years, 45.4% women) from four of nine provinces in South Africa. Results indicate that current alcohol was relatively more common among male (40.7%) than female youths (21.3%). Similarly, hazardous or harmful drinking was more prevalent among males (24.3%) than among women (12.9%). In multivariable analyses among men and women high on sexually permissiveness had hazardous or harmful alcohol use. Lifestyle including high peer pressure, and spending more nights away in a week were associated with hazardous or harmful alcohol use. 相似文献

The aim of this study was to investigate the association between post-traumatic stress disorder (PTSD) and health risk behaviours among persons 15 years and older in South Africa. We analysed data from the South African National Health and Nutrition Examination Survey (SANHANES-1, 2012) (N = 15 201; mean age = 36.9 years, SD = 16.5; 2.1% with PSTD, 4.0% with partial PTSD). The survey included questions from validated measures of the following health risk behaviours: problem drinking, current tobacco use, physical activity, sedentary behaviour, vegetable consumption, and fast food and frequent soft drinks consumption. In adjusted logistic regression analysis, only self-reporting with PTSD was associated with problem drinking. The data did not yield significant association between PTSD status and any of the other health risk behaviours (tobacco use, low physical activity, and fast food consumption). 相似文献

Context: This paper reports on a qualitative study looking at the perceptions of clients who use drugs and are on low income. Research suggests that counselling services can experience difficulties in reaching and retaining such clients, and outcomes of counselling can be disappointing. Aim: To learn from clients who had engaged in counselling for over six months what difference it had made to their lives. Method: Grounded theory methodology was used to analyse semi‐structured interviews with six participants. Findings: Findings included changes in the clients’ internal world, their connectedness with society, their familiarity with counselling, and their perception of the relationship with the counsellor. Factors within the counselling process which helped and hindered change were identified. The study documents how participants were able to use counselling to improve their lives. 相似文献

The purpose of the current study was to determine if smoking on high-school property was associated with increased risk for other substance use among U.S. adolescents. Secondary analyses were carried out with data from the 2011 Youth Risk Behavior Survey (YRBS, N = 15,503). Only adolescents who reported smoking at least one cigarette in the last 30 days were selected for analyses (n = 2531, 44% female). Alcohol, marijuana, and cocaine use was assessed among participants. Binary logistic regression analysis was carried out to examine the relationship between smoking on school property (yes versus no) with each of the substance use variables. Adolescent smokers who reported smoking on school property were significantly more likely to report substance use across all substances examined compared to smokers who did not smoke on campus. For example, campus smokers were 3.91 times more likely to use marijuana in their lifetime and 3.85 times more likely to have used crack or cocaine in their lifetime compared to smokers who did not smoke on campus. Health care providers who provide services to adolescents should screen for smoking on school property to help identify adolescents at increased risk for substance use. 相似文献

Risk reduction interventions that promote condom use, a vital component of most HIV prevention interventions, have been successful in increasing condom use among African American adolescents. Understanding theoretical components that lead to behavior change and selecting relevant risk reduction messages remain important considerations for targeting new interventions and tailoring existing interventions. The present study sought to (1) identify the most important theoretical determinants of condom use intention in African American adolescent males and females, separately, using the integrative model of behavior prediction, and (2) identify underlying beliefs within the determinants that were good candidates for message development in similar interventions. Using 446 African American adolescents, multi‐group SEM indicated that the gender‐specific IM exhibited a better fit than the overall model. Specifically, the IM had a stronger capacity for predicting condom use intention and condom use behavior for adolescent boys. Using a specific criteria for message selection, specific condom use beliefs were discussed as potential candidate messages for both African American males and females. 相似文献

Executive control is impaired from the early stages of Alzheimer's Disease (AD) and this produces deregulated semantic cognition (Corbett, Jefferies, Burns, & Lambon Ralph, 2012 ; Perry, Watson, & Hodges, 2000 ). While control deficits should affect semantic retrieval across all modalities, previous studies have typically focused on verbal semantic tasks. Even when non‐verbal semantic tasks have been used, these have typically employed simple picture‐matching tasks, which may be influenced by abnormalities in covert naming. Therefore, in the present study, we examined 10 patients with AD on a battery of object‐use tasks, in order to advance our understanding of the origins of non‐verbal semantic deficits in this population. The AD patients’ deficits were contrasted with previously published performance on the same tasks within two additional groups of patients, displaying either semantic degradation (semantic dementia) or deregulation of semantic retrieval (semantic aphasia; Corbett, Jefferies, Ehsan, & Lambon Ralph, 2009 ). While overall accuracy was comparable to the scores in both other groups, the AD patients’ object‐use impairment most closely resembled that observed in SA; they exhibited poorer performance on comprehension tasks that placed strong demands on executive control. A similar pattern was observed in the expressive domain: the AD and SA groups were relatively good at straightforward object use compared to executively demanding, mechanical puzzles. Error types also differed: while all patients omitted essential actions, the SA and AD groups’ demonstrations also featured unrelated intrusions. An association between AD patients’ object use and their scores on standard executive measures suggested that control deficits contributed to their non‐verbal semantic deficits. Moreover, in a task specifically designed to manipulate executive demand, patients with AD (and SA) exhibited difficulty in thinking flexibly about the non‐canonical uses of everyday objects, especially when distracted by semantically related objects. This study provides converging evidence for the notion that a failure of regulatory control contributes to multimodal semantic impairment in AD and uniquely demonstrates this pattern for the highly non‐verbal domain of object use. 相似文献
