Predictors of participation in a school-based anti-tobacco activism program.

This study investigated the predictors of participation in a school-based, anti-tobacco activism program. Subjects in this study consisted of 7th grade students participating in the intervention component of Project S.H.

The association between teacher attitudes, behavioral intentions, and smoking and the prevalence of smoking among seventh-grade students.

Seventh-grade students and teachers from twenty-three middle and junior high schools were surveyed to determine the association between teacher attitudes, behavioral intentions, and smoking behavior and the prevalence of student smoking. Teacher attitudes toward smoking policies were found to be strongly related to the current smoking behavior of the teacher but not consistently related to student smoking. In addition, teacher likelihood of intervening showed a modest association with teacher smoking status, with current smokers generally indicating being the least likely to intervene for student possession or use of cigarettes.

Differences in cancer-risk-related behaviors in Latino and Anglo adults.

METHODS. Latino (n = 358) and Anglo (n = 113) adults living in the San Diego area were surveyed on nutrition, smoking, and cancer screening behaviors. The Latino respondents were dichotomized into a low (L-Latino) or high (H-Latino) acculturation group according to a median split of an acculturation index.

Long-term structural changes in pH-sensitive hydrogels.

The long-term swelling properties of lightly cross-linked copolymer hydrogels consisting of methyl methacrylate (MMA) and N,N-dimethylaminoethyl methacrylamide (DMAA) were studied as a function of pH at 25 degrees C and 37 degrees C. In acidic pH regions, the swelling equilibria were found to be stable over 200 d. In alkaline pH environments, however, the 'equilibrium' swelling increases slowly with time.

Effects of a peer-led AIDS intervention with university students.

Acquired immune deficiency syndrome (AIDS) has become a major health threat to university students. This study evaluated a peer-led AIDS intervention program with university students (1) increase knowledge of human immunodeficiency virus (HIV) transmission and infection; (2) change attitudes to reflect scientific information on AIDS-related facts; and (3) change behavioral intentions to correspond with safer sexual practices. Subjects were students (N = 142) from four undergraduate classes and were predominantly female (65%), white (82%), and sexually active (86%).

Depression late after combat: a follow-up of Finnish World War Two veterans from the seven countries east-west cohort.

An analysis from the Finnish East and West Cohort of the Seven Countries Study tested the hypothesis that front line service during modern warfare is associated with depression later in life. World War Two-era Finnish combat veterans were compared to Finnish veterans who were non-combatants. Both groups were followed from 1959 to 1984.

Correlates of health facilitator performance in a tobacco use prevention program: implications for recruitment.

Tobacco use prevention programs vary by type of health facilitator used to deliver the intervention. Because program outcome may be related to the characteristics of a health facilitator, this study investigated the association between the characteristics of 29 college undergraduate health facilitators of an adolescent tobacco use prevention program with their scores on manageability and inclass performance scales. Results indicated health facilitators who rated themselves as outgoing, adventurous, analytical, and were older rated higher on the inclass performance scale.

Assessing skills for refusing cigarettes and smokeless tobacco.

Hops and colleagues developed an audiotaped refusals skills test in which students respond to cigarette offers and their responses are scored for content. The present study employed a modified analogue skills test. Modifications included adding a separate subscale for smokeless tobacco, emphasizing repeated offers and group pressure, and rating the quality of responses (good, fair, poor).

Stages of adolescent tobacco-use acquisition.

The present study extended the results of previous research in applying the "stages of acquisition" model to the onset of smokeless tobacco as well as cigarette use. Three expert judges classified an initial pool of items as to whether they represented "precontemplation," "contemplation," "action," or "maintenance" stages of smokeless tobacco acquisition. Fifty items with adequate inter-rater reliability were combined with 21 previously developed items pertaining to cigarette smoking acquisition in an overall tobacco acquisition questionnaire, which in turn was administered to 358 junior and senior high public school students.

Preventive attitudes, beliefs, and practices of physicians in fee-for-service and health maintenance organization settings.

To identify the self-reported differences in preventive practices, attitudes, and beliefs of physicians practicing in fee-for-service (FFS) and health maintenance organization (HMO) settings, we surveyed a 100% sample of primary care physicians practicing in a large, urban, closed-panel HMO and a random sample of physicians, in the same county, who were in an FFS practice. The FFS physicians were more likely to consider behavioral risk factors important than were HMO physicians, and they were more likely to ask their patients about behavioral risk factors. Fee-for-service physicians were more likely than HMO physicians to use continuing medical education courses to upgrade their skills in modifying behavioral risk factors.

The social epidemiology of smoking during pregnancy among Mexican women.

The association between maternal tobacco smoke exposure and hazards to reproduction has been investigated since the turn of the century. Numerous studies have demonstrated an increased risk to the developing fetus as a result of maternal smoking. This risk continues to manifest itself postnatally into childhood.

Generic tobacco use among four ethnic groups in a school age population.

The prevalence of overall or "generic" tobacco use among Hispanic, white, Black and Asian youths in grades four, seven, ten and twelve was compared in San Diego, California (n = 4980). Significant differences in generic tobacco use between ethnic groups were found in the 4th, 10th and 12th grades, but were greatest in the 10th grade. Only white youths demonstrated a sharp increase in regular tobacco use (once a month or more) between 7th and 10th grade.

Tobacco use prevention and health facilitator effectiveness.

Tobacco prevention programs often use peers to teach refusal skills to other adolescents. College undergraduate health facilitators delivered a tobacco prevention intervention to sixth and seventh grade students in six schools. Outside observers evaluated facilitators in seven categories: being prepared, maintaining class control, keeping students' attention, encouraging participation, communication, relating to students, and working well in a team.

Immunochemical heterogeneity of calcitonin in man: effect on radioimmunoassay.

Determinations of blood levels of human calcitonin by radioimmunoassay have varied considerably in different laboratories. Much of the controversy over calcitonin levels can be attributed to the multiplicity of immunoreactive forms of the hormone (iCT), the differing region specificities of the antisera utilized for measurement by radioimmunoassay, protein effects, different rates of degradation of the various iCT fractions and the specific methodology of the radioimmunoassay.
