A critical assessment of theories/models used in health communication for HIV/AIDS.

Most theories and models used to develop human immunodeficiency virus (HIV)/acquired immune deficiency syndrome (AIDS) communication are based on social psychology that emphasizes individualism. Researchers including communication and health scholars are now questioning the presumed global relevance of these models and thus the need to develop innovative theories and models that take into account regional contexts. In this paper, we discuss the commonly used theories and models in HIV/AIDS communication. Furthermore, we argue that the flaws in the application of the commonly used "classical" models in health communication are because of contextual differences in locations where these models are applied. That is to say that these theories and models are being applied in contexts for which they were not designed. For example, the differences in health behaviors are often the function of culture. Therefore, culture should be viewed for its strength and not always as a barrier. The metaphorical coupling of "culture" and "barrier" needs to be exposed, deconstructed, and reconstructed so that new, positive, cultural linkages can be forged. The HIV/AIDS pandemic has served as a flashpoint to either highlight the importance or deny the relevance of theories and models while at the same time addressing the importance of culture in the development and implementation of communication programs.

Toward a new communications framework for HIV/AIDS.

In response to the overwhelming burden of new cases of human immunodeficiency virus (HIV) in Africa, Asia, Latin America, and the Caribbean, the Joint United Nations Programme on HIV/AIDS (UNAIDS), in 1997, initiated a project to examine the application of existing communication theories/models to HIV/acquired immune deficiency virus (AIDS) prevention and care in these regions. In the past 2 years, 103 leading researchers and practitioners from different parts of the world were invited by the UNAIDS to participate in one of five consultative workshops designed to review these theories/models and rethink their adequacy for Africa, Asia, Latin America, and the Caribbean. A new communications framework for HIV/AIDS was developed to move from a focus on the individual to a focus on five domains of "contexts" that influence behaviors: government policy, socioeconomic status (SES), culture, gender relations, and spirituality.

Cultural aspects of African American eating patterns.

The high mortality from diet-related diseases among African Americans strongly suggests a need to adopt diets lower in total fat, saturated fat and salt and higher in fiber. However, such changes would be contrary to some traditional African American cultural practices. Focus group interviews were used to explore cultural aspects of eating patterns among low- and middle-income African Americans recruited from an urban community in Pennsylvania. In total, 21 males and 32 females, aged 13-65+ years were recruited using a networking technique. Participants identified eating practices commonly attributed to African Americans and felt that these were largely independent of socioeconomic status. They were uncertain about links between African American eating patterns and African origins but clear about influences of slavery and economic disadvantage. The perception that African American food patterns were characteristically adaptive to external conditions, suggest that, for effective dietary change in African American communities, changes in the food availability will need to precede or take place in parallel with changes recommended to individuals. Cultural attitudes about where and with whom food is eaten emerged as being equivalent in importance to attitudes about specific foods. These findings emphasize the importance of continued efforts to identify ways to increase the relevance of cultural context and meanings in dietary counseling so that health and nutrition interventions are anchored in values as perceived, in this case, by African Americans.

Health promotion and the discourse on culture: implications for empowerment.

To invoke the primacy of culture in health education activities is not only to challenge approaches to health education that overlook or downplay this domain, but to also deepen and extend the possibilities of progressive approaches that focus on culture. Border pedagogy, which seeks to establish a countervoice to Eurocentrism and patriarchy, enhances and magnifies the possibilities that were opened up when critical pedagogy invoked the engagement of students in the production of knowledge. This process of engaging the teacher/interventionists and the students/audiences in the production of meaning, value, pleasure, and knowledge should be central to the mission of health education. It is only through such dialogue where varied cultural expressions are affirmed and centralized that the production of cultural identity can be legitimating and empowering relative to health promotion.

Predicting alcohol impairment: perceived intoxication versus BAC.

The purpose of this study was to report the relationship among perceived intoxication, performance impairment, and actual blood alcohol concentration (BAC) levels. Fifteen subjects, aged 21 to 40, completed both single- and double-dose sessions of alcohol consumption. BACs, reaction and anticipation time, and perceived intoxication data were collected during both sessions. Analysis of data showed that perceived intoxication was significantly related to performance impairment, but the actual BAC was not.

Variability in behavioral impairment involved in the rising and falling BAC curve.

The purpose of this pilot study was to measure variability in behavior impairment at specific levels of the rising and falling blood alcohol concentration (BAC) curve. Behavior impairment was measured for anticipation and reaction time in addition to a variety of visual skills. Also of interest was the variability in impairment involved at specific BAC levels under single-dose and double-dose conditions. The experimental design was a variation on a 2 x 2 factorial with repeated measures on the dose of alcohol. All subjects took part in two experimental sessions, single-dose and double-dose. Sixteen (8 male and 8 female) paid subjects ages 21-40 participated in the study. Testing procedures included repeated measures on reaction time, anticipation time, perceptual vision acuity and depth perception. Breath-alcohol measures were sampled continuously at 5-minute intervals and used to plot absorption time, peak BAC and elimination time. Results showed that the average peak BAC for the double-dose was significantly higher than that of the single-dose condition. However, there were no significant differences between the single-dose and double-dose condition in either absorption time or elimination time. The performance pattern for reaction time, anticipation time and depth perception showed more impairment in the rising BAC limb than in the falling BAC limb. It is noteworthy that specific individuals exhibited different levels of impairment at a given BAC level, depending on whether the session was single- or double-dose, suggesting that one's current BAC level is less a measure of impairment than is the total quantity of alcohol consumed. A follow-up procedure to examine practice effects was conducted on eight volunteer students. Identical testing procedures, using no alcohol, produced no significant practice effects after a 3-hour period.

Psychomotor and visual performance under the time-course effect of alcohol.

This study examined reaction time (RT), anticipation time (AT), and visual performance under the influence of blood alcohol concentration (BAC), using a repeated-measures design. Subjects (8 men and 8 women), 21 to 40 yr. of age, participated in both single- and double-dose sessions, in which they drank approximately 2.3 oz. and 4.6 oz. of 86-proof vodka, respectively. The breath BAC was measured at 5-min. intervals. The RT, AT, and visual performance were tested every 20 min. for 140 min. in both sessions. In general, results indicated that RT, AT, and stereoscopic vision were impaired more in the rising BAC curve than the falling BAC curve. In addition, the impairment tended to be greater for the double-dose than the single-dose session. The far and near visual acuities were not affected by the BAC.

HIV/AIDS education and prevention among African-Americans: a focus on culture.

African-Americans have emerged as the "second wave" of the AIDS epidemic. Epidemiologic evidence indicates that African-Americans adults as well as adolescents have a disproportionately higher risk of AIDS and human immunodeficiency virus (HIV) infection. While programs designed to increase self-protective behaviors are urgently needed to avert a further increase in HIV infection among this population, there is little understanding of African-American sociocultural factors that may influence the acceptance of HIV information and the adoption of HIV-preventive behaviors. This paper describes African-American cultural values and mores which may be related to risk-taking behavior. Barriers to the effective dissemination of HIV prevention education are identified and strategies that may be effective in surmounting these barriers and implementing culturally-appropriate HIV behavioral modification programs are described.

Cross-cultural health education: a pedagogical challenge.

Multicultural education is a necessary ingredient for promoting cultural diversity in the U.S. educational system. School health curricula should incorporate instruction about health problems among ethnic minorities. If we are to educate youth for what we want the future of society to be, educators must encourage and promote diversity. In school health curricula, diversity is critical to adequately promote health for all.

Cultural identity and health lifestyles among African Americans: a new direction for health intervention research?

OBJECTIVES: To assess associations of cultural and personal identity variables with socioeconomic status (SES) and health lifestyle in African Americans. DESIGN: Cross-sectional. METHODS: A questionnaire administered to 333 African Americans, ages 40-70 years, at enrollment in a nutrition education study assessed: African-American cultural identity (15 items scored 1 [low] to 4 [high]); reference group (two questions about perceived success in the Black or White way of life-scored as bi-cultural if "yes" to both); personal identity (4 items on: self-concept as attractive, self-confident, satisfied and friendly-scored 1 [no/not sure] or 2 [yes]); and selected demographic and lifestyle variables. RESULTS: Cultural identity factors reflecting participation in and belonging to African-American culture and bi-cultural reference group were related to higher SES, lower fat diets, not smoking, current drinking, and higher leisure time physical activity (cultural identity only), particularly in women (P<.001 to P = .06). Associations of cultural identity with physical activity and of bi-cultural reference group with low-fat eating and not smoking (females) remained significant at P<.05 after adjustment for SES. CONCLUSIONS: A greater emphasis is needed on aspects of cultural identity that are positively related to health lifestyles as distinct from aspects that might act as barriers.
