Smoking, internalized heterosexism, and HIV disease management among male couples.

High rates of cigarette smoking have been observed among HIV-positive individuals. Smoking has been linked to HIV-related medical complications and non-AIDS defining cancers and negatively impacts on immune function and virologic control. Although internalized heterosexism has been related to smoking behaviors, little is known about associations between partners' reports of smoking, internalized heterosexism, and HIV medication management in male couples with HIV. A sample of 266 male couples completed baseline assessments for a cohort study examining relationship factors and HIV treatment. A computer-based survey assessed self-reported smoking behaviors, alcohol use, internalized heterosexism, and antiretroviral therapy (ART) adherence. HIV-positive men also provided blood samples to assess viral load. Approximately 30% of the sample reported that they are currently smoking cigarettes. After adjusting for demographic characteristics, men in a primary relationship with a partner who reported currently smoking had more than five-fold greater odds of reporting smoking. Higher levels of internalized heterosexism and financial hardship were each independently associated with greater odds of reporting smoking. Among HIV-positive men on ART (n = 371), having a partner who reported smoking was associated with almost three-fold greater odds of having a detectable viral load. Our findings add new support to the evidence of romantic partners influencing each other's health behaviors, and demonstrate an association between smoking and disease management within male couples. Future research should explore the interpersonal and social contexts of smoking in order to develop interventions that meet the unique needs of male couples.

Personal or relational? Examining sexual health in the context of HIV serodiscordant same-sex male couples.

Couples' ability to adopt a "we" orientation has been associated with optimal health outcomes. This study examined how personal and relational motivations are uniquely associated with unprotected anal intercourse (UAI), protected anal intercourse (PAI), and the absence of sexual activity within HIV-serodiscordant same-sex male couples. HIV-positive men and their HIV-negative partners (N = 116 couples, 232 men) completed questionnaires and HIV-positive men had blood drawn for viral load. Results of a multinomial logistic regression illustrated that sexual satisfaction was positively associated with PAI among HIV-negative partners and negatively associated with PAI among HIV-positive partners. Endorsing a "we" orientation was positively associated with PAI among HIV-positive partners. Findings suggest that HIV-positive partners who espouse a "we" orientation may be willing to forgo their personal interests to protect their HIV-negative partners from HIV transmission. Couples-based interventions are warranted to help strengthen relationship dynamics to enhance the sexual health of serodiscordant couples.

A population-based study of how children are exposed to saliva in KwaZulu-Natal Province, South Africa: implications for the spread of saliva-borne pathogens to children.

OBJECTIVES: In sub-Saharan Africa, many viral infections, including Epstein-Barr virus, cytomegalovirus, Kaposi's sarcoma-associated herpesvirus and hepatitis B are acquired in childhood. While saliva is an important transmission conduit for these viruses, little is known about how saliva is passed to African children. We endeavoured to identify the range and determinants of acts by which African children are exposed to saliva. METHODS: To identify the range of acts by which African children are exposed to saliva, we conducted focus groups, semi-structured interviews and participant observations in an urban and a rural community in South Africa. To measure the prevalence and determinants of the identified acts, we administered a questionnaire to a population-based sample of caregivers. RESULTS: We identified 12 caregiving practices that expose a child's oral-respiratory mucosa, cutaneous surfaces or anal-rectal mucosa to saliva. Several acts were heretofore not described in the contemporary literature (e.g., caregiver inserting finger lubricated with saliva into child's rectum to relieve constipation). Among 896 participants in the population-based survey, many of the acts were commonly practised by all respondent types (mothers, fathers, grandmothers and siblings). The most common were premastication of food, sharing sweets and premastication of medicinal plants that are spit onto a child's body. CONCLUSIONS: African children are exposed to saliva through a variety of acts, practised by a variety of caregivers, with no single predominant practice. This diversity poses challenges for epidemiologic work seeking to identify specific saliva-passing practices that transmit viruses. Most acts could be replaced by other actions and are theoretically preventable.

Religion and HIV/AIDS stigma: implications for health professionals in Puerto Rico.

Abstract HIV/AIDS stigma continues to be a barrier for prevention efforts. Its detrimental effects have been documented among people living with HIV/AIDS and encompass loss of social support and depression. When it is manifested by health professionals, it can lead to sub-optimal services. Although strides have been made to document the effects of HIV/AIDS stigma, much needs to be done in order to understand the structural factors that can foster it. Such is the case of religion's role on HIV/AIDS stigma in Puerto Rico. The Caribbean Island has a Judeo-Christian-based culture due to years of Spanish colonisation. This religious influence continued under Protestantism as part of the Island's integration as a non-incorporated territory of the USA. The main objective of this study was to explore the role of religion in HIV/AIDS stigma manifested by Puerto Rican health professionals in practice and in training. Through a mixed-method approach, 501 health professionals completed qualitative interviews (n=80) and self-administered questionnaires (n=421). Results show that religion plays some role in conceptualisations of health and illness among participants in the study. Furthermore, the importance placed on religion and participation in such activities was related to higher levels of HIV/AIDS stigma.

Power analysis for multivariate and repeated measures designs: a flexible approach using the SPSS MANOVA procedure.

Although power analysis is an important component in the planning and implementation of research designs, it is often ignored. Computer programs for performing power analysis are available, but most have limitations, particularly for complex multivariate designs. An SPSS procedure is presented that can be used for calculating power for univariate, multivariate, and repeated measures models with and without time-varying and time-constant covariates. Three examples provide a framework for calculating power via this method: an ANCOVA, a MANOVA, and a repeated measures ANOVA with two or more groups. The benefits and limitations of this procedure are discussed.
