Synopsis

The Extended Parallel Process Model (EPPM) was developed as a model to assist in the development of effective risk communication messages, specifically messages that elicit adaptive behavioral responses. It has shown to be effective in several settings invoking clearly delineated dangers (e.g., safety belt usage, condom usage).Unfortunately, communicating risk messages is not always so straightforward. One increasing concern in the risk communication field is the controversy over electromagnetic fields (EMFs) and the uncertain hazards they present to individuals. The purpose of this study is to test the EPPM with this unknown risk and to explore which type of risk message may motivate adaptive behavioral responses. In accordance with the EPPM model, 251 participants received either a low- or high-threat risk message and a list of control measures they could use to reduce their exposure to EMFs. Results suggest that the EPPM model can be extended to an unknown risk.

Stability ball training (SBT) is believed to improve spinal stability (SS) and could reduce the risk of back pain in sedentary individuals. The purpose of this study was to examine the effects of SBT on SS. Twenty sedentary individuals were randomly assigned to either an experimental group that performed SBT twice per week for 10 weeks or to a control group. Differences between groups were assessed by analysis of variance (ANOVA) with repeated measures. The experimental group improved significantly (p < 0.05) on the static back-endurance test from pretest (149.3 +/- 72.3 seconds) to posttest (194.6 +/- 56.7 seconds) and the side bridge test from pretest (45.4 +/- 39.4 seconds) to posttest (71.3 +/- 59.7 seconds). Back endurance for the control group did not change from pretest (123.4 +/- 64.9 seconds) to posttest (87.5 +/- 40.2 seconds), nor did the results of the side bridge test change for this group from pretest (41.8 +/- 26.4 seconds) to posttest (51.6 +/- 35.9 seconds). These findings illustrate that SBT may provide improvements in SS within this population. Practitioners might use SBT exercises where the position of the spine is maintained during the early phases of back-pain prevention programs. This type of programming might be beneficial to individuals who spend a good deal of time sitting (i.e., in corporate fitness programs) or for individuals who are prone to back pain and have been cleared to exercise. Also, the side bridge and static back endurance assessments may be good choices for measuring SS in field settings.

By the year 2020, 20% of the U.S. population will be age 65 years or older. From a health care perspective, there is growing concern about the aging population. Little is known about the elderly and their use of alternative therapies. This study included data from the National Survey of Midlife Development in the United States (MIDUS). Three-hundred and thirty-five participants between the ages of 65 and 74 completed the interview and mailback questionnaire. Onehundred and forty-five individuals (43.3%) reported using alternative medicine therapies during the past year. The most common types of alternative medicine utilized were as follows: spiritual practices, exercise/movement therapies, special diets, chiropractic, and meditation. Income, education, and sex of respondent were found to be predictors of alternative therapy use among this age group. Results from this study could provide conventional practitioners greater awareness of the health beliefs and practices of their young-old patients.

Human papillomavirus (HPV) infections are one of the most common types of sexually transmitted infections in the United States. The highest rates of HPV infection are found in adult’s ages 18-28 years. This study utilizes the Health Belief Model to assess knowledge and perception of HPV infection and cervical cancer in college-age women and their intent to reduce their numbers of sex partners and request that their partner wear a condom during their next sexual encounter to prevent HPV infection. Even though most college women have heard of HPV, it appears that 79.5% of women in this study rated their subjective knowledge of HPV as poor, and only 58% knew that a vaccine now exists to prevent HPV infection. HPV health promotion campaigns should do more to incorporate HPV vaccine education in STD and HPV educational interventions.
