Condom use among gay/bisexual male substance abusers using the timeline follow-back method.

Sexual risk for HIV transmission under the influence of alcohol and/or other drugs is not simply a cause-effect relationship: not everyone who drinks or uses other drugs has unprotected sex. The purpose of this study is to explore differences between substance using gay/bisexual men who use condoms during anal sex from those who do not. These differences are identified by comparing men whose anal sex while under the influence of alcohol and/or drugs is consistently protected to men whose anal sex while under the influence of alcohol and/or drugs is consistently unprotected. Gay/bisexual men entering substance abuse treatment at a gay-identified agency in San Francisco were recruited to complete surveys and to be interviewed about sexual behavior, substance use, and related variables using an extended version of the Timeline Follow-back (TL). The TL procedure uses a blank calendar form and a series of questions to cue recall of drinking, drug use, and anal intercourse on each of the 30 days prior to the last date of alcohol and/or drug use. Men whose anal sex while under the influence of alcohol and/or drugs is consistently unprotected were significantly more likely to report having less than a college education (p = .04), more likely to have an income of less than $20,000 (p = .01), more likely to use amyl nitrite (p = .01) and cocaine (p = .02), and more likely to report a higher frequency of anal sex (p = .007). In addition, they were less likely to approve of sex without love (p = .003), less likely to perceive that safer sex is the community norm (p < .001), and less likely to have encouragement from friends to practice safer sex (p = .001). However, HIV status did not differentiate between the two groups. These two groups provide clear and interesting contrasts in terms of behavior, thus comparisons of the factors influencing sexual safety in these subgroups may enhance our understanding of risk taking. A better understanding of possible mediating variables can be important both in guiding future research in this area and in formulating intervention strategies to target gay men who drink or use drugs in combination with sexual activity.

Effect of minor illness on serum cholesterol level.

To ascertain the impact of minor illness on total plasma cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), we analyzed data collected on 6,880 persons examined for the Stanford Five-City Project. Overall, 8.4% of the population reported having a minor illness on the day of examination, although there were substantial variations in minor illness rates with season, city, and year of data collection. After adjustment for age, sex, body mass index, season, and city of residence, we found that those who reported minor illness at the time of examination had a lower mean TC than those who were well (195.9 mg/dL versus 201.2 mg/dL, P less than .005). HDL-C was 51.2 mg/dL in persons with minor illness, and 52.3 mg/dL in persons without (P = .13). Dietary recall data covering the 24-hour period before the examination was available on a subset of the patients. No dietary differences appeared between individuals who reported minor illness and those who did not. In a subset of 162 persons with a minor illness who were followed longitudinally for up to six years, TC adjusted for age was 191.8 mg/dL with minor illness and 196.1 mg/dL without, a difference that was not statistically significant. The results of this study imply that minor illness may contribute to some of the biological variability of TC and HDL-C. Although small, a differential rate of minor illness may sometimes significantly affect interpretation of TC epidemiological and intervention studies or the timing of measurements in clinical practice.
