A Prospective Study of Sensation Seeking and Alcohol Use as Predictors of Sexual Risk Behaviors Among Men and Women Receiving Sexually Transmitted Infection Clinic Services.

Sensation seeking, the propensity to seek optimal stimulation and engage in risk behaviors, correlates with alcohol expectancies, which are related to alcohol use in sexual situations, potentially increasing risks for sexually transmitted infections (STIs). In the current prospective study of 313 male and 140 female STI clinic patients, path analyses showed that sensation seeking predicted unprotected intercourse 6 months later. Sensation seeking also predicted alcohol outcome expectancies, which predicted alcohol use in sexual contexts 6 months later, which in turn predicted unprotected sex. Tests for mediation showed that alcohol expectancies accounted for the association between sensation seeking and alcohol use in sexual contexts. These findings replicate previous research, with the prospective design confirming directional hypotheses and supporting causal conclusions.

Health information on the Internet and people living with HIV/AIDS: Information evaluation and coping styles.

[Correction Notice: An erratum for this article was reported in Vol 26(5) of Health Psychology (see record 2007-13009-005). Table 1 mistakenly reported that the correlation between total Internet use and gender was r = .14, which, given the coding for gender, would be interpreted as women using the Internet more than men. However, as correctly stated in the text and indicated throughout the rest of the article, men used the Internet significantly more than women. The correct correlation between total Internet use and gender in Table 1 should therefore be r = .14.] Individuals who seek information on the Internet to cope with chronic illness may be vulnerable to misinformation and unfounded claims. This study examined the association between health-related coping and the evaluation of health information. Men (n = 347) and women (n = 72) who were living with HIV/AIDS and reported currently using the Internet completed measures assessing their Internet use. Health Web sites downloaded from the Internet were also rated for quality of information. HIV-positive adults commonly used the Internet to find health information (66%) and to learn about clinical trials (25%); they also talked to their physicians about information found online (24%). In a multivariate analysis, assigning higher credibility to unfounded Internet information was predicted by lower incomes, less education, and avoidant coping styles. People who cope by avoiding health information may be vulnerable to misinformation and unfounded claims that are commonly encountered on the Internet.

Sensation seeking, alcohol use, and sexual behaviors among sexually transmitted infection clinic patients in Cape Town, South Africa.

Alcohol use is associated with risks for HIV/AIDS. The association between alcohol and sexual risk may be accounted for by sensation seeking personality. However, sensation seeking in relation to substance use and HIV risk has not been examined in Africa. In this study, 292 men and 219 women receiving sexually transmitted infection (STI) diagnostic and treatment services in Cape Town, South Africa, completed anonymous behavioral surveys. Structural modeling was used to test a model of alcohol use and sensation seeking in relation to sexual risk behaviors. Results showed that sensation seeking and alcohol use in sexual contexts were related to HIV risks, controlling for gender and marital status. The association between sensation seeking and HIV risk was partly accounted for by alcohol use in proximity to sex. In contrast to studies conducted in the United States, sensation seeking was not related to alcohol-sex outcome expectancies. These findings suggest that alcohol use is an important HIV transmission risk factor for many STI clinic patients and that interventions for individuals who are characterized as sensation seekers are urgently needed in South Africa.

Changes in HIV treatment beliefs and sexual risk behaviors among gay and bisexual men, 1997-2005.

Objective: Beliefs about HIV treatment effectiveness and the impact of HIV treatments on HIV transmission risks were initially related to sexual risk-taking in the late 1990s when multidrug HIV treatments first became available. This study examined changes in beliefs about the effects of HIV treatment for preventing HIV transmission and their association to sexual risk behaviors between the years 1997 and 2005. Design: Anonymous surveys were administered to a convenience sample of gay and bisexual men attending a large community event in Atlanta, Georgia in 1997 (N = 498) and again at the same community event in 2005 (N = 448). Analyses were performed for men living with HIV/AIDS and for men who have not been diagnosed with HIV/AIDS. Main Outcome Measures: Rates of unprotected anal intercourse in the previous 3 months. Results: There were significant increases in high-risk sexual practices that coincided with increased beliefs that HIV treatments can reduce the chance of transmitting HIV. However, optimistic beliefs about the health benefits of HIV treatments decreased over the 8 years and were not related to risk behaviors. Conclusions: Beliefs about how HIV treatments impact HIV infectiousness remain associated with HIV transmission risk behavior and interventions targeting at-risk as well as HIV-positive men who have sex with men must directly address these beliefs and perceptions.

Internet-based health information consumer skills intervention for people living with HIV/AIDS.

Medical information can improve health, and there is an enormous amount of health information available on the Internet. A randomized clinical trial tested the effectiveness of an intervention based on social- cognitive theory to improve information use among people living with HIV/AIDS. Men and women (N = 448) were placed in either (a) an 8-session intervention that focused on Internet information consumer skills or (b) a time-matched support group and were followed to 9 months postintervention. The Internet skills group demonstrated greater Internet use for health, information coping, and social support compared with the control group. The authors conclude that people with HIV infection may benefit from increased access to health information on the Internet and that vulnerability to misinformation and fraud can be reduced through behavioral interventions.

Effect of iodine status and other nutritional factors on psychomotor and cognitive performance of Filipino schoolchildren

BACKGROUND: Until 1998, iodine deficiency was a public health problem in the Philippines. A law entitled "An Act Promoting Salt Iodization Nationwide" (ASIN) has been passed and implemented by the government to eliminate iodine deficiency. The contribution of salt iodization, as well as dietary, health, and environmental factors, to improving the intellectual performance of Filipino schoolchildren remains to be determined. OBJECTIVE: The objectives of the study were to determine the relationship between iodine status and levels of psychomotor and cognitive performance in first-grade children aged 6 to 10 years, and to examine the extent to which dietary, biochemical, health, and environmental factors contribute to children's mental performance. METHODS: Two hundred ninety children in six classroom sections from a public school in Manila were examined by measurement of urinary iodine excretion (UIE) and thyroid palpation. The median UIE level for each section was determined. Sixty-five children classified as iodine deficient (UIE < 90 microg/L with grade 1 goiter, n = 34) and non-iodine deficient (UIE > 100 microg/L without goiter, n = 31) were given psychomotor and cognitive function tests (Bender-Gestalt and Raven's Colored Progressive Matrices). Scores from the two tests were used to determine each child's general ability percentile rank. Other variables examined were dietary intake (% RDA of nutrients ingested based on two nonconsecutive 24-hour recalls); deficiencies in iron, vitamin A, and selenium; parasitic infection; coliform contamination of drinking water; household use of iodized salt; illness in the past 2 weeks; and wasting and stunting. RESULTS: Children whose general ability scores were at or above the 50th percentile had higher UIE levels, but the relationship was not significant. Children from sections with higher median UIE levels had higher percentile ranks for general ability (p = .002). Backward logistic regression showed that the variance in deficient and adequate mental performance was explained by dietary intakes that met > or = 80% of the RDA for energy, protein, thiamin, and riboflavin; the use of iodized salt; child's iodine status; and stunting (R2 = .520, p = .0016). Higher class median UIE was associated with better psychomotor and cognitive performance in children who were tested. Factors that contributed to better performance include higher intakes of energy, protein, thiamin, and riboflavin; household use of iodized salt; normal iodine status; and absence of stunting or chronic malnutrition. CONCLUSIONS: Salt iodization, accompanied by adequate intakes of energy, protein, and foods rich in thiamin and riboflavin, can contribute to improved mental performance in Filipino schoolchildren. Longer-term factors that can contribute to improved performance are achievement of normal iodine status and elimination of protein-energy malnutrition.     

Experimental Components Analysis of Brief Theory-Based HIV/AIDS Risk-Reduction Counseling for Sexually Transmitted Infection Patients.

An experimental components analysis of brief HIV risk-reduction counseling based on the information-motivation-behavioral skills (IMB) model was conducted with 432 men and 193 women receiving sexually transmitted infection (STI) clinic services. Following baseline assessments, participants were randomly assigned to 1 of 4 90-min risk-reduction counseling sessions that deconstructed the IMB model within a full factorial design. Participants were followed for 9 months, with STI diagnoses monitored over 12 months. Men who received the full IMB session evidenced relatively greater use of risk-reduction behavioral skills and relatively lower rates of unprotected intercourse over 6-months follow-up and had fewer new STIs. For women, however, the motivational counseling demonstrated the most positive outcomes. Results suggest that brief single-exposure HIV prevention counseling can reduce HIV transmission risks.
