Worldwide more than 22 million children and adolescents are exposed to repetitive head impacts (RHI) in soccer. Evidence indicates cumulative effects on brain structure, but it is not known whether exposure to RHI affects cognitive improvement in adolescents. To determine whether exposure to RHI while heading the ball in soccer affects improvement in cognitive performance in adolescents over time.The study group consisted of a convenience sample of 16 male soccer players (mean age 15.7±0.7 years). A comparison cohort of 14 male non-contact sports athletes (mean age 14.9±1.1 years) was recruited from competitive athletic clubs and group-matched on age. Using the ProPoint and AntiPoint tasks, sensorimotor and cognitive functions were measured over both immediate (pre-versus posttraining) as well as across multiple time points within a play season. The number and type of head impacts that occurred during the training were counted. The main outcome measure was the change in response time (RT) in the ProPoint and AntiPoint tasks. The immediate (pre-versus post-training) and longer-term (across a play season) change in RT was analyzed and the effect of the number and type of head impacts was tested.Thirty athletes with and without exposure to RHI demonstrated a decrease in RT in both tasks immediately after training. Over the play season, both groups showed improvement in sensorimotor function. However, while the Control group also improved in cognitive performance, the soccer players did not. Further, the more long headers performed, the slower the improvement in RT over the season.Youth athletes experience an immediate cognitive improvement after training most likely due to physical exercise. Results of this study also suggest an association between exposure to specific RHI (long headers) and lack of improvement in cognitive performance in youth athletes over time.
Objective-Explore use, cost, and satisfaction with the quality and effectiveness of complementary therapy among older rural adults. Design-Descriptive survey.Sample-A random sample of 325 older adults from rural communities throughout Montana and North Dakota. Measurements-Participants were interviewed by telephone.Results-Only 57 participants (17.5%) had used complementary providers and most sought this care for chronic problems, heard about providers through word-of-mouth information, and were satisfied with the care. A total of 35.7% (116) used self-directed complementary practices and most used these practices for health promotion, heard about them through informal sources, and found them to be at least somewhat helpful. Of the 325 participants, 45.2% (147) used some form of complementary care, e.g., providers, self-directed practices, or both. Participants used as much complementary care as is found in national studies. Most spent relatively little out-of-pocket for complementary care.Conclusions-Understanding the health care choices that older rural residents make, including complementary health care, is paramount for a comprehensive approach to meeting their health care needs. Keywords alternative therapy; complementary therapy use; older adults; rural healthIn the past several decades, there has been extraordinary growth in the attention paid to complementary therapy, in both the popular and the research arenas. Complementary therapy has been defined as a group of diverse health care systems, practices, and products that are not presently considered an integral part of allopathic health care (National Center for Complementary and Alternative Medicine, 2004; http://nccam.nih.gov/health/whatiscam/). Examples include therapies provided by practitioners such as chiropractic, acupuncture, and NIH-PA Author ManuscriptNIH-PA Author Manuscript NIH-PA Author Manuscript massage therapy, as well as self-directed practices such as nutritional and herbal supplements, meditation, and use of magnets.The fact that U.S. residents are using complementary therapy and that this use has grown over the past several decades is well documented in the literature (Astin, 1998;Eisenberg, Davis, Ettner, & Appel, 1998;McFarland, Bigelow, Zani, Newson, & Kapian, 2002;Paramore, 1997;Wolsko et al., 2000). Between 1990 and 1997, the use of complementary therapy in the United States increased by 25%, and 1997 expenditures grew to approximately $21.2 billion, with more than half of this amount out of pocket (Eisenberg et al., 1998). This exceeded the 1997 out-of-pocket spending on hospitalizations. Complementary therapy has become sufficiently mainstreamed for coverage by several health insurance plans ("Hospital plunges," 1996). Therapies that, in the past, were used as a last resort for chronic illnesses are now used as primary treatments (Paramore, 1997). These trends have far-reaching implications for community/public health nurses and other health care professionals who assist communitydwelling clients with the management o...
This article aims to present and describe a model of complementary and alternative medicine (CAM) health literacy. The model is the conceptual basis for CAM health literacy, which is operationally defined as the information about CAM needed to make informed self-management decisions regarding health. Improving health literacy is a national priority, and widespread use of CAM has added to the complexity of this task. There are no currently available models or measures of health literacy regarding CAM. The authors developed the model using an iterative process of deriving concepts, constructs, and empirical indicators from the literature and the author’s prior work, review and critique by experts, and revision. The model of CAM health literacy can serve as the basis for future research on the use and efficacy of CAM and the constructs and concepts within it can be used to identify points of intervention for research or for clinical practice. It is anticipated that the model will have scientific and clinical application for assessing health literacy in other self care decision-making situations.
By improving the existing understanding of who is or is not likely to use CAM, the results of this study can be used in giving comprehensive care for rural women, including all healthcare practices, self-care and practitioner provided, and complementary and conventional.
