Why Americans eat what they do: taste, nutrition, cost, convenience, and weight control concerns as influences on food consumption.

OBJECTIVE: To examine the self-reported importance of taste, nutrition, cost, convenience, and weight control on personal dietary choices and whether these factors vary across demographic groups, are associated with lifestyle choices related to health (termed health lifestyle), and actually predict eating behavior. DESIGN: Data are based on responses to 2 self-administered cross-sectional surveys. The main outcomes measured were consumption of fruits and vegetables, fast foods, cheese, and breakfast cereals, which were determined on the basis of responses to questions about usual and recent consumption and a food diary. SUBJECTS/SETTING: Respondents were a national sample of 2,967 adults. Response rates were 71% to the first survey and 77% to the second survey (which was sent to people who completed the first survey). STATISTICAL ANALYSES: Univariate analyses were used to describe importance ratings, bivariate analyses (correlations and t tests) were used to examine demographic and lifestyle differences on importance measures, and multivariate analyses (general linear models) were used to predict lifestyle cluster membership and food consumption. RESULTS: Respondents reported that taste is the most important influence on their food choices, followed by cost. Demographic and health lifestyle differences were evident across all 5 importance measures. The importance of nutrition and the importance of weight control were predicted best by subject's membership in a particular health lifestyle cluster. When eating behaviors were examined, demographic measures and membership in a health lifestyle cluster predicted consumption of fruits and vegetables, fast foods, cheese, and breakfast cereal. The importance placed on taste, nutrition, cost, convenience, and weight control also predicted types of foods consumed. APPLICATIONS: Our results suggest that nutritional concerns, per sc, are of less relevance to most people than taste and cost. One implication is that nutrition education programs should attempt to design and promote nutritious diets as being tasty and inexpensive.

Effects of an HIV risk reduction project on sexual risk behavior of low-income STD patients.

A 10-hour small-group informational and skill-building intervention was tested among patients (N = 472) attending publicly funded sexually transmitted disease clinics in Maryland, Georgia, and New Jersey. After completing a 90-minute interview concerning HIV risk behaviors, condom use self-efficacy and condom outcome expectancies, participants were randomized to either an intervention or a control condition. Participants in both conditions displayed significant reductions in unprotected encounters and number of partners and increases in condom use. No differences between treatment conditions were observed, indicating that the motivational effects of the interview may have been stronger than the effects of the intervention in this population.

Relative risk in the news media: a quantification of misrepresentation.

OBJECTIVES: This study quantifies the representativeness with which the print news media depict mortality. METHODS: The proportion of mortality-related copy in samples of national print media was compared with the proportion of actual deaths attributable to the leading causes of US mortality over a 1-year period. RESULTS: For every tested cause of death, a significant disproportion was found between amount of text devoted to the cause and the actual number of attributable deaths. Underrepresented causes included tobacco use (23% of expected copy) and heart disease (33%); overrepresented causes included illicit use of drugs (1740%), motor vehicles (1280%), and toxic agents (1070%). CONCLUSIONS: The news media significantly misrepresent the prevalence of leading causes of death and their risk factors. This misrepresentation may contribute to the public's distorted perceptions of health threats.

Measurement of condom use self-efficacy and outcome expectancies in a geographically diverse group of STD patients.

The aim of this project was to conduct an initial evaluation among sexually transmitted disease (STD) patients of the psychometric properties of two instruments: the National Institute of Mental Health (NIMH) multisite condom use self-efficacy scale and the NIMH multisite condom use outcome expectancy scale. The condom use self-efficacy scale was designed to measure one's degree of confidence in various aspects of condom use, whereas the outcome expectancy scale was designed to measure one's belief about the consequences of using condoms. Using a sample of 641 patients from five geographically diverse STD clinics in the eastern United States, initial reliability coefficients were computed. The alpha coefficient for the self-efficacy scale was .91 and for the outcome expectancy scale .88, indicating high internal consistency for both scales. Both scales were analyzed using common factor analytic procedures. Five factors emerged from the analysis of the self-efficacy scale and six factors from the analysis of the outcome expectancy scale. Reliability coefficients for the individual factors ranged from .76 to .86. Construct validity of each scale was assessed by hypothesis testing. As predicted, participants with higher levels of self-efficacy and more positive outcome expectancies were more likely to use condoms.

Mother and adolescent knowledge of sexual development: the effects of gender, age, and sexual experience.

As part of a larger study on the impact of personal and family characteristics on adolescents' HIV risk and risk-reduction behavior, 90 adolescents and 73 mothers were asked to define in their own words seven terms related to sexual development: ejaculation, hormones, menstruation, ovulation, puberty, semen, and wet dreams. Mother and adolescent knowledge of sexual development terms and the effects of age and sexual experience on that knowledge were examined. Results suggest that the mothers were not able to adequately define the sexual development terms and thus may be ill-prepared to teach their children about sex or reinforce information they learn in school. Since adolescent knowledge did not significantly increase with age and sexual experience, the researchers suggest that continuing sex education about normal sexual development is needed.

Advances in public health communication.

There have been tremendous advances in recent years in the innovative use of communication to address public health problems. This article outlines the use of communication techniques and technologies to (positively) influence individuals, populations, and organizations for the purpose of promoting conditions conducive to human and environmental health. The approaches described include social marketing, risk communication, and behavioral decision theory, entertainment education, media advocacy, and interactive decision support systems. We also address criticism of these approaches among public health professionals because of perceived discrepancies in their inherent goals and objectives. In conclusion, we call for the rapid diffusion of state-of-the-art public health communication practices into public health service agencies and organizations.

Focus groups: an interview method for nursing research.

Focus groups present an ideal way for nurse researchers to collect preliminary information about an area of research interest. The information obtained can lead to greater understanding of phenomena or can be used to develop more extensive quantitative studies. Following the recommendations for conducting a focus group as described in this article and focus group manuals can lead to a worthwhile and enjoyable experience for all involved.

Use of the cognitive assessment method to evaluate the adequacy of sexually transmitted disease history questions.

Cognitive assessment is an approach used to evaluate questions in survey interviews. This approach is useful in delineating measurement error due to participants' understanding of terms and interpretation of questions. The purpose of this study was to evaluate the quality of questionnaire items designed to evaluate history of sexually transmitted diseases (STDs) using a cognitive assessment approach. Participants recruited from an STD clinic were asked up to six questions to assess their history of STDs. Verbal probes were used after each question in an attempt to evaluate the participants' understanding of the questions and methods they used to recall episodes of having STDs. The findings revealed that respondents did not understand the medical terms for some STDs, that the wording of one question potentially interfered with respondents' comprehension of the question, and that respondents used an episodic recall method to determine their number of previous STD infections. Cognitive assessment is a useful method for identifying potential sources of respondent-induced measurement error.

Placebo-controlled comparison of spirapril at 6, 12 and 24 mg/day in mild to severe essential hypertension.

In a double-blind, parallel-group study, 260 patients with mild to severe essential hypertension were randomized to treatment with placebo or spirapril at 6, 12 or 24 mg once daily for 6 weeks. When blood pressures were measured at the end of the dosing interval (trough), all spirapril regimens had produced similar reductions in sitting systolic and diastolic blood pressures (siSBP/siDBP) which were significantly greater than those observed in placebo-treated patients. There were no relevant changes in resting heart rate in any of the study groups. At the study endpoint, the mean reductions in siSBP/siDBP were 14.9/11.5 mmHg with spirapril at 6 mg, 15.4/12.0 mmHg with spirapril at 12 mg and 17.8/12.4 mmHg with spirapril at 24 mg/day vs. 3.1/3.6 mmHg with placebo. In a subgroup of 122 patients, blood pressure was recorded at the end of the dosing interval and during the 8 hours immediately postdose to monitor the peak effects on blood pressure. All spirapril dosages produced similar reductions at peak with a mean decrease of siDBP of approximately 20 mmHg in comparison to baseline values vs 6-7 mmHg with placebo. The trough:peak ratios for 6, 12 and 24 mg all lay between 60% and 90% for siSBP and siDBP, indicating that most of the peak effect was maintained at trough. Spirapril was well tolerated; the adverse event profile was not different from that with placebo, and no dose-related adverse events were observed.(ABSTRACT TRUNCATED AT 250 WORDS)
