Anthropometric, strength, endurance and flexibility characteristics of elite and recreational climbers.

There has been remarkable development in the scope and quality of rock climbing in recent years. However, there are scant data on the anthropometry, strength, endurance and flexibility of rock climbers. The aim of this study was to compare these characteristics in three groups of subjects-elite rock climbers, recreational climbers and non-climbers. The 30 male subjects were aged 28.8 +/- 8.1 (mean +/- S.D.) years. Group 1 (n = 10) comprised elite rock climbers who had led a climb of a minimum standard of 'E1' (E1-E9 are the highest climbing grades) within the previous 12 months; Group 2 (n = 10) comprised rock climbers who had achieved a standard no better than leading a climb considered 'severe' (a low climbing grade category); and Group 3 (n = 10) comprised physically active individuals who had not previously done any rock climbing. The test battery included tests of finger strength [grip strength, pincer (i.e. thumb and forefinger) strength, finger strength measured on climbing-specific apparatus], body dimensions, body composition, flexibility, arm strength and endurance, and abdominal endurance. The tests which resulted in significant differences (P < 0.05) between the three groups included the bent arm hang (elite 53.1 +/- 1.32 s; recreational 31.4 +/- 9.0 s; non-climbers 32.6 +/- 15.0 s) and pull-ups (elite 16.2 +/- 7.2 repetitions; recreational 3.0 +/- 4.0 reps; non-climbers 3.0 +/- 3.9 reps); for both tests, the elite climbers performed significantly better than the recreational climbers and non-climbers. Regression procedures (i.e. analysis of covariance) were used to examine the influence of body mass and length. Using adjusted means (i.e. for body mass and leg length), significant differences were obtained for the following: (1) finger strength, grip 1, four fingers (right hand) (elite 447 +/- 30 N; recreational 359 +/- 29 N; non-climbers 309 +/- 30 N), (2) grip strength (left hand) (elite 526 +/- 21 N; recreational 445 +/- 21 N; non-climbers 440 +/- 21 N), (3) pincer strength (right hand) (elite 95 +/- 5 N; recreational 69 +/- 5 N; non-climbers 70 +/- 5 N) and (4) leg span (elite 139 +/- 4 cm; recreational 122 +/- 4 cm; non-climbers 124 +/- 4 cm). For tests 3 and 4, the elite climbers performed significantly better than the recreational climbers and non-climbers for any variable. These results demonstrate that elite climbers have greater shoulder girdle endurance, finger strength and hip flexibility than recreational climbers and non-climbers. Those who aspire to lead 'E1' standard climbs or above should consider training programmes to enhance their finger strength, shoulder girdle strength and endurance, and hip flexibility.

A descriptive study of the status of therapeutic recreation at the seven state-operated comprehensive rehabilitation centers in the United States.

The intent of this article is to present a systematic overview of therapeutic recreation services at the seven state-operated Comprehensive Rehabilitation Centers. These seven Centers are located in Hot Springs, Arkansas; Warm Spring, Georgia; Thelma, Kentucky; Baltimore, Maryland; Johnstown, Pennsylvania; Institute, West Virginia; and Fisherville, Virginia. This paper is a result of a study which was conducted from October 1978 to May 1979. The study showed that each of the Centers provided recreation and leisure activities: however, none of the Centers utilized therapeutic recreation as the title of their specific department. In general, the Centers have difficulties in the following areas: 1. defining therapeutic recreation; 2. structuring their department; 3. delivery of therapeutic recreation services; 4. conception of therapeutic recreation as part of the rehabilitation process; 5. inadequately trained personnel in leadership and supervisory positions; 6. staff training; 7. assessment and evaluation instruments for clients; 8. discharge planning; and 9. recreation therapy as a treatment component within the delivery of therapeutic recreation services, All of which need resolution. The research demonstrated that most of the recreation directors saw a need for therapeutic recreation services to be refined further to meet the needs and abilities of the clients.

Surveillance for waterborne-disease outbreaks associated with recreational water--United States, 2001-2002.

PROBLEM/CONDITION: Since 1971, CDC, the U.S. Environmental Protection Agency, and the Council of State and Territorial Epidemiologists have maintained a collaborative surveillance system for collecting and periodically reporting data related to occurrences and causes of waterborne-disease outbreaks (WBDOs) related to drinking water; tabulation of recreational water-associated outbreaks was added to the surveillance system in 1978. This surveillance system is the primary source of data concerning the scope and effects of waterborne disease outbreaks on persons in the United States. REPORTING PERIOD COVERED: This summary includes data on WBDOs associated with recreational water that occurred during January 2001-December 2002 and on a previously unreported outbreak that occurred during 1998. DESCRIPTION OF SYSTEM: Public health departments in the states, territories, localities, and the Freely Associated States are primarily responsible for detecting and investigating WBDOs and voluntarily reporting them to CDC on a standard form. The surveillance system includes data for outbreaks associated with both drinking water and recreational water; only outbreaks associated with recreational water are reported in this summary. RESULTS: During 2001-2002, a total of 65 WBDOs associated with recreational water were reported by 23 states. These 65 outbreaks caused illness among an estimated 2,536 persons; 61 persons were hospitalized, eight of whom died. This is the largest number of recreational water-associated outbreaks to occur since reporting began in 1978; the number of recreational water-associated outbreaks has increased significantly during this period (p<0.01). Of these 65 outbreaks, 30 (46.2%) involved gastroenteritis. The etiologic agent was identified in 23 (76.7%) of these 30 outbreaks; 18 (60.0%) of the 30 were associated with swimming or wading pools. Eight (12.3%) of the 65 recreational water-associated disease outbreaks were attributed to single cases of primary amebic meningoencephalitis caused by Naegleria fowleri; all eight cases were fatal and were associated with swimming in a lake (n = seven; 87.5%) or river (n = one; 12.5%). Of the 65 outbreaks, 21 (32.3%) involved dermatitis; 20 (95.2%) of these 21 outbreaks were associated with spas or pools. In addition, one outbreak of Pontiac fever associated with a spa was reported to CDC. Four (6.1%) of the 65 outbreaks involved acute respiratory illness associated with chemical exposure at pools. INTERPRETATION: The 30 outbreaks involving gastroenteritis comprised the largest proportion of recreational water-associated outbreaks during this reporting period. These outbreaks were associated most frequently with Cryptosporidium (50.0%) in treated water venues and with toxigenic Escherichia coli (25.0%) and norovirus (25.0%) in freshwater venues. The increase in the number of outbreaks since 1993 could reflect improved surveillance and reporting at the local and state level, a true increase in the number of WBDOs, or a combination of these factors. PUBLIC HEALTH ACTION: CDC uses surveillance data to identify the etiologic agents, types of aquatics venues, water-treatment systems, and deficiencies associated with outbreaks and to evaluate the adequacy of efforts (e.g., regulations and public awareness activities) for providing safe recreational water. Surveillance data are also used to establish public health prevention priorities, which might lead to improved water-quality regulations at the local, state, and federal levels.

Recreation and risk: potential exposure.

The Department of Energy and other federal facilities are reclaiming land through the process of remediation and restoration, and this land will eventually be turned over for future land uses that may involve recreation. Understanding the amount of recreation that is likely (and thus individual exposure) is an essential element in decisions about cleanup standards. In this article the number of days people engage in different recreational activities as a measure of potential exposure is examined. People attending a Mayfest celebration (n = 399) and the Palmetto Sportsmen's Classic (n = 285) in Columbia, SC, were interviewed regarding their recreational activities. In most cases reported in the literature, recreational activities are examined as the mean number of days people engage in each activity per year, but to determine risk it is essential to know the distribution of these activities. In descending order of frequency, people attending the Mayfest reported their activities as birdwatching, photographing, fishing, hiking, camping, and hunting. There were significant gender differences in the frequency of activities, with men spending more days in every activity except birdwatching and photography. There were ethnic differences in recreation, with whites engaging in higher levels of most recreational activities than blacks, but the percentage of black men who reported fishing more than 100 d per year was greater than for white men. Most people reported their participation in most activities less than 30 d per year; however, a higher percentage of people reported participating in photography, birdwatching, and fishing more than 30 d per year compared to the other activities. Further, individuals at the Sportsman's Classic reported far higher rates of hunting and fishing per year than the general public. These data can be used to examine potential exposure of recreationists on remediated and restored land. The data clearly indicate that over 25% of the people engage in at least one recreational activity over 20 d per year, and thus exceed the Department of Energy's 14-d recreation assumption in its future land use document.

Health correlates of recreational gambling in older adults.

OBJECTIVE: Prior studies have found high rates of alcohol use and abuse/dependence, depression, bankruptcy, and incarceration associated with recreational gambling. Despite growing rates of recreational gambling in older adults, little is known regarding its health correlates in this age group. The objective of this study was to identify health and well-being correlates of past-year recreational gambling in adults age 65 years and older, compared to adults age 18-64 years. METHOD: The Gambling Impact and Behavior Study surveyed by telephone a nationally representative sample of 2,417 adults. Multivariate analyses were used to compare past-year recreational gamblers and nongamblers in the older and younger age groups on measures of alcohol use and abuse/dependence, substance abuse/dependence, depression, mental health treatment, subjective general health, incarceration, and bankruptcy. Additional analyses compared the gambling patterns in older and younger adult past-year recreational gamblers. RESULTS: After the effects of sociodemographic factors were controlled, older adult past-year recreational gamblers were more likely to report past-year alcohol use and better health than were older nongamblers. Multivariate analyses investigating interactions of gambling and age found that higher rates of good to excellent subjective general health in recreational gamblers were mainly attributable to the older age group. Older adult gamblers were more likely than younger adult gamblers to begin gambling after age 18 years, to gamble more frequently, and to report a larger maximum win. CONCLUSIONS: Recreational gambling patterns of older adults differ from those of younger adults. In contrast to findings in younger adults, recreational gambling in older adults is not associated with negative measures of health and well-being.

Surveillance for waterborne disease and outbreaks associated with recreational water--United States, 2003-2004.

PROBLEM/CONDITION: Since 1971, CDC, the U.S. Environmental Protection Agency, and the Council of State and Territorial Epidemiologists have collaboratively maintained the Waterborne Disease and Outbreak Surveillance System for collecting and reporting waterborne disease and outbreak (WBDO)-related data. In 1978, WBDOs associated with recreational water (natural and treated water) were added. This system is the primary source of data regarding the scope and effects of WBDOs in the United States. REPORTING PERIOD: Data presented summarize WBDOs associated with recreational water that occurred during January 2003-December 2004 and one previously unreported outbreak from 2002. DESCRIPTION OF THE SYSTEM: Public health departments in the states, territories, localities, and the Freely Associated States (i.e., the Republic of the Marshall Islands, the Federated States of Micronesia, and the Republic of Palau, formerly parts of the U.S.-administered Trust Territory of the Pacific Islands) have primary responsibility for detecting, investigating, and voluntarily reporting WBDOs to CDC. Although the surveillance system includes data for WBDOs associated with drinking water, recreational water, and water not intended for drinking, only cases and outbreaks associated with recreational water are summarized in this report. RESULTS: During 2003-2004, a total 62 WBDOs associated with recreational water were reported by 26 states and Guam. Illness occurred in 2,698 persons, resulting in 58 hospitalizations and one death. The median outbreak size was 14 persons (range: 1-617 persons). Of the 62 WBDOs, 30 (48.4%) were outbreaks of gastroenteritis that resulted from infectious agents, chemicals, or toxins; 13 (21.0%) were outbreaks of dermatitis; and seven (11.3%) were outbreaks of acute respiratory illness (ARI). The remaining 12 WBDOs resulted in primary amebic meningoencephalitis (n = one), meningitis (n = one), leptospirosis (n = one), otitis externa (n = one), and mixed illnesses (n = eight). WBDOs associated with gastroenteritis resulted in 1,945 (72.1%) of 2,698 illnesses. Forty-three (69.4%) WBDOs occurred at treated water venues, resulting in 2,446 (90.7%) cases of illness. The etiologic agent was confirmed in 44 (71.0%) of the 62 WBDOs, suspected in 15 (24.2%), and unidentified in three (4.8%). Twenty (32.3%) WBDOs had a bacterial etiology; 15 (24.2%), parasitic; six (9.7%), viral; and three (4.8%), chemical or toxin. Among the 30 gastroenteritis outbreaks, Cryptosporidium was confirmed as the causal agent in 11 (36.7%), and all except one of these outbreaks occurred in treated water venues where Cryptosporidium caused 55.6% (10/18) of the gastroenteritis outbreaks. In this report, 142 Vibrio illnesses (reported to the Cholera and Other Vibrio Illness Surveillance System) that were associated with recreational water exposure were analyzed separately. The most commonly reported species were Vibrio vulnificus, V. alginolyticus, and V. parahaemolyticus. V. vulnificus illnesses associated with recreational water exposure had the highest Vibrio illness hospitalization (87.2%) and mortality (12.8%) rates. INTERPRETATION: The number of WBDOs summarized in this report and the trends in recreational water-associated disease and outbreaks are consistent with previous years. Outbreaks, especially the largest ones, are most likely to be associated with summer months, treated water venues, and gastrointestinal illness. Approximately 60% of illnesses reported for 2003-2004 were associated with the seven largest outbreaks (>100 cases). Deficiencies leading to WBDOs included problems with water quality, venue design, usage, and maintenance. PUBLIC HEALTH ACTIONS: CDC uses WBDO surveillance data to 1) identify the etiologic agents, types of aquatic venues, water-treatment systems, and deficiencies associated with outbreaks; 2) evaluate the adequacy of efforts (i.e., regulations and public awareness activities) to provide safe recreational water; and 3) establish public health prevention priorities that might lead to improved regulations and prevention measures at the local, state, and federal levels.

Recreation and risk around Los Alamos: are Hispanics more at risk?

The Department of Energy (DOE) and other federal facilities are involved in massive remediation and restoration efforts on lands that may eventually be turned over for recreation or other uses by the public. In addition, other sites are expected to continue their ongoing missions, but recreation may be sanctioned, or not discouraged, on their remediated lands. Understanding the amount and types of recreation of regional residents who might use such lands, as well as their willingness to use these lands, is critical to determining both cleanup and restoration standards, and potential future risk. In this article the recreational rates, current recreational use, and willingness to recreate on Los Alamos National Laboratory in New Mexico are examined for 356 people interviewed at a well-attended gun show in Albuquerque, NM. There were few significant ethnic differences in recreational rates, although Hispanics had higher fishing rates and lower bird-watching rates than whites. Women hunted less, and photographed more, than men. Younger people fished and hunted more, and bird-watched less, than older people. There were no differences in recreational rates as a function of income or education. These data can be used for understanding potential exposure of people in the vicinity of Los Alamos.

Incidence of sports and recreation related injuries resulting in hospitalization in Wisconsin in 2000.

OBJECTIVE: To describe the incidence and patterns of sports and recreation related injuries resulting in inpatient hospitalization in Wisconsin. Although much sports and recreation related injury research has focused on the emergency department setting, little is known about the scope or characteristics of more severe sports injuries resulting in hospitalization. SETTING: The Wisconsin Bureau of Health Information (BHI) maintains hospital inpatient discharge data through a statewide mandatory reporting system. The database contains demographic and health information on all patients hospitalized in acute care non-federal hospitals in Wisconsin. METHODS: The authors developed a classification scheme based on the International Classification of Diseases External cause of injury code (E code) to identify hospitalizations for sports and recreation related injuries from the BHI data files (2000). Due to the uncertainty within E codes in specifying sports and recreation related injuries, the authors used Bayesian analysis to model the incidence of these types of injuries. RESULTS: There were 1714 (95% credible interval 1499 to 2022) sports and recreation-related injury hospitalizations in Wisconsin in 2000 (32.0 per 100,000 population). The most common mechanisms of injury were being struck by/against an object in sports (6.4 per 100,000 population) and pedal cycle riding (6.2 per 100,000). Ten to 19 year olds had the highest rate of sports and recreation related injury hospitalization (65.3 per 100,000 population), and males overall had a rate four times higher than females. CONCLUSIONS: Over 1700 sports and recreation related injuries occurred in Wisconsin in 2000 that were treated during an inpatient hospitalization. Sports and recreation activities result in a substantial number of serious, as well as minor injuries. Prevention efforts aimed at reducing injuries while continuing to promote participation in physical activity for all ages are critical.

Protecting public health from the impact of body-contact recreation.

Population growth and the increasing demand for recreational opportunities have put public and political pressure on water purveyors to make every water body available for multipurpose use. There is increasing evidence that full water-body contact recreation such as swimming, and water/jet skiing may add significantly more microorganisms such as viruses, Giardia, and Cryptosporidium to a water body when compared with non-body contact recreational waters. Body-contact recreation also poses a risk to the consumer inadvertently ingesting contaminated water. Waterborne disease outbreaks caused by recreation are well documented with the endemic rate and the risk level to the public estimated to be very high. Since 1989, 171 outbreaks, associated with recreational water, have been documented in the USA with more than 15,000 individuals infected; these outbreaks occurred in both natural and artificial settings. Discussions on the recently published Long-Term 2 Enhanced Surface Water Treatment Rule (LT2) have focused on varied treatment goals related to microbiological quality and source water protection methods at the heart of this discussion. This paper highlights new studies on risk from recreation, proposed beach standards, modeling to assess the risk of infection, political issues associated with limiting recreation, and what water utilities can do to reduce risk.

Promoting community recreation and leisure.

PURPOSE: The aim of this study was to investigate the nature and level of involvement a cross section of pediatric physical therapists (PTs) and pediatric occupational therapists (OTs) have achieved in promoting community recreation and leisure participation for their clients with disabilities. METHOD: Using the current Internal Classification of Functioning and Disability, a hierarchy of skills required to promote community recreation and leisure was constructed and a survey was developed based on items contained in the hierarchy. Items represented three potential types of barriers to participation in community recreation and leisure for individuals with disabilities: (1) physical, (2) social, and (3) resource. One hundred fifty-two therapists were surveyed regarding their knowledge and awareness of potential barriers to their clients' participation in community recreation and leisure and were asked questions related to promotion of recreation and leisure to their pediatric clients. RESULTS: Eighty-two surveys were completed and returned. Data revealed that therapists were practicing below an "optimal" level regarding the promotion of recreation and leisure for their clients with disabilities. No significant differences were found between PTs and OTs other than a slightly greater tendency for PTs to consider cost as a barrier to client participation in recreation and leisure pursuits. CONCLUSIONS: More research is indicated to establish the factors contributing to what may be inadequate promotion of community recreation and leisure participation among pediatric therapists.

Recreation, consumption of wild game, risk, and the Department of Energy sites: perceptions of people attending the Lewiston, ID, "Roundup".

Several federal agencies are reclaiming land through remediation and restoration, and are considering potential future land uses that are compatible with current land uses and local needs. Understanding potential recreational and wild game consumption patterns and risk perceptions are critical for determining cleanup levels and assessing potential risk associated with certain uses. In this article, recreational rates of people attending the Lewiston "Roundup" rodeo in northwestern Idaho were examined, as well as their perceptions of the safety of consuming fish and game from two Department of Energy (DOE) facilities: the Hanford Site and the Idaho National Engineering and Environmental Laboratory (INEEL). These are two of DOE's largest sites. Lewiston is closer to Hanford, but is in the same state as INEEL. Men engaged in significantly higher hunting and fishing rates than women, but there were no gender differences in camping and hiking rates. Rates of hunting and camping decreased significantly with age, while rates of hiking were lowest for 31- to 45-yr-olds. Level of education generally was not related to rates of recreation. Over 70% of the subjects ate deer, elk, and self-caught fish; 30-50% ate grouse, moose, and waterfowl; and fewer people ate other game species. Overall, subjects were less concerned about eating the fish and game from INEEL than from Hanford, and more people thought Hanford should be cleaned up completely compared to INEEL. Mean rates of fishing, hiking, and camping all exceeded the DOE's maximum recreational exposure assumption of 14 d/yr used in their future use documents. Although at present people are generally not allowed access to DOE lands for recreation, recreation is one future land use being considered for these federal facilities. Given that some people would engage in multiple activities, the potential exists for people living in the general region of Hanford and INEEL to exceed the 14-d exposure assumption. The relative gender differences in recreational rates mean that men are potentially more at risk, particularly since hunting (on both sites) and fishing (on Hanford) are attractive.

A comparison of the anthropometric, strength, endurance and flexibility characteristics of female elite and recreational climbers and non-climbers.

There is limited information on the anthropometry, strength, endurance and flexibility of female rock climbers. The aim of this study was to compare these characteristics in three groups of females: Group 1 comprised 10 elite climbers aged 31.3 +/- 5.0 years (mean +/- s) who had led to a standard of 'hard very severe'; Group 2 consisted of 10 recreational climbers aged 24.1 +/- 4.0 years who had led to a standard of 'severe'; and Group 3 comprised 10 physically active individuals aged 28.5 +/- 5.0 years who had not previously rock-climbed. The tests included finger strength (grip strength, finger strength measured on climbing-specific apparatus), flexibility, bent arm hang and pull-ups. Regression procedures (analysis of covariance) were used to examine the influence of body mass, leg length, height and age. For finger strength, the elite climbers recorded significantly higher values (P < 0.05) than the recreational climbers and non-climbers (four fingers, right hand: elite 321 +/- 18 N, recreational 251 +/- 14 N, non-climbers 256 +/- 15 N; four fingers, left hand: elite 307 +/- 14 N, recreational 248 +/- 12 N, non-climbers 243 +/- 11 N). For grip strength of the right hand, the elite climbers recorded significantly higher values than the recreational climbers only (elite 338 +/- 12 N, recreational 289 +/- 10 N, non-climbers 307 +/- 11 N). The results suggest that elite climbers have greater finger strength than recreational climbers and non-climbers.

Positive affect among nursing home residents with Alzheimer's dementia: the effect of recreational activity.

The experience of positive emotions is an integral component of quality of life. Research suggests that cognitive deficits in persons with dementia may impede their ability to generate pleasurable moments and hence decrease their positive affect. Therefore, structured recreation activities may have the potential to significantly improve resident affect. However, differences in affect between ordinary time and recreation time are not well known. The present study used previously published structured-observation instruments to measure affect and behaviour among 35 dementia residents at two nursing homes in Japan during ordinary time and during recreation time. A total of 3,854 one-minute observations were coded. Dementia residents expressed happiness over seven times more often during recreation time than during ordinary time. Over 60% of ordinary time was solitary, with 65.72% of all observed affect being 'Null Affect'. A total of 43.75% of residents expressed happiness only during recreation time. In addition 48.9% of all behaviour during 'Ordinary Time' was coded as 'Null Behaviour', which indicated that the resident was sitting and doing nothing. Findings indicate that recreation time is significantly higher in positive affect than ordinary time and that virtually all residents benefited from recreation.

Developmental approaches to therapeutic recreation programming: a new research focus.

Therapeutic Recreation is being increasingly recognized as a valuable element of a total rehabilitation approach. In order to be effectively utilized as a treatment tool however, recreation must be approached in a scientific manner which gears activities to individual skills, interests and rehabilitation goals. Many programs in the past have been based primarily on what the therapeutic recreation specialist thought was best, rather than relying on objective analysis of client needs. In actuality this should not be the case. A more scientific approach is evolving as professionals learn more about the physical and psychological ramifications of recreation participation. Analysis of activity demands and outcomes can be used to match participation with client needs and interests to provide a recreation program that is truly rehabilitative as well as enjoyable. This manuscript provides a review of the benefits of Therapeutic Recreation and describes why it is important to utilize scientific and objective criteria in program planning. A number of models are identified that have developed systems approaches to Therapeutic Recreation programming. A recent model, developed at New York University, is described in detail and some projections for the future are made.

Recreational injuries among older Americans, 2001.

OBJECTIVE: To describe the epidemiology of non-fatal recreational injuries among older adults treated in United States emergency departments including national estimates of the number of injuries, types of recreational activities, and diagnoses. METHODS: Injury data were provided by the National Electronic Injury Surveillance System-All Injury Program (NEISS-AIP), a nationally representative subsample of 66 out of 100 NEISS hospitals. Potential cases were identified using the NEISS-AIP definition of a sport and recreation injury. The authors then reviewed the two line narrative to identify injuries related to participation in a sport or recreational activity among men and women more than 64 years old. RESULTS: In 2001, an estimated 62 164 (95% confidence interval 35 570 to 88 758) persons >/=65 years old were treated in emergency departments for injuries sustained while participating in sport or recreational activities. The overall injury rate was 177.3/100 000 population with higher rates for men (242.5/100 000) than for women (151.3/100 000). Exercising caused 30% of injuries among women and bicycling caused 17% of injuries among men. Twenty seven percent of all treated injuries were fractures and women (34%) were more likely than men (21%) to suffer fractures. CONCLUSIONS: Recreational activities were a frequent cause of injuries among older adults. Fractures were common. Many of these injuries are potentially preventable. As more persons engage in recreational activities, applying known injury prevention strategies will help to reduce the incidence of these injuries.

Recreational physical activity and risk of prostate cancer in a large cohort of U.S. men.

Physical activity has been proposed as a modifiable risk factor for prostate cancer because of its potential effects on circulating hormones such as testosterone and insulin. We examined the association of various measures of physical activity with prostate cancer risk among men in the American Cancer Society Cancer Prevention Study II Nutrition Cohort, a large prospective study of U.S. adults. Information on recreational physical activity was obtained from a self-administered questionnaire completed at cohort enrollment in 1992/1993, as well as from a questionnaire completed as part of an earlier study in 1982. During the 9-year prospective follow-up, 5,503 incident prostate cancer cases were identified among 72,174 men who were cancer-free at enrollment. Cox proportional hazards modeling was used to compute hazard rate ratios (RR) for measures of recreational physical activity and to adjust for potential confounding factors. We observed no difference in risk of prostate cancer between men who engaged in the highest level of recreational physical activity (>35 metabolic equivalent-hours/wk) and those who reported no recreational physical activity at baseline (RR, 0.90; 95% confidence interval, 0.78-1.04; P for trend = 0.31). We also did not observe an association between prostate cancer and recalled physical activity at age 40 or exercise reported in 1982. However, the incidence of aggressive prostate cancer was inversely associated with >35 metabolic equivalent-hours/wk of recreational physical activity compared with that in men who reported no recreational physical activity (RR, 0.69; 95% confidence interval, 0.52-0.92; P for trend = 0.06). Our findings are consistent with most previous studies that found no association between recreational physical activity and overall prostate cancer risk but suggest physical activity may be associated with reduced risk of aggressive prostate cancer.

Recreational drugs. Societal and professional issues.

Recreational drug use presents a challenge to society and, in particular, the profession of nursing. Recreational drug use must be appreciated for the implications it presents for the episodes of abuse and development of chronic health problems. The effects and recreational use of volatile substances, cannabis, opioids, barbiturates, benzodiazepines, amphetamines, cocaine, psychedelics, and designer drugs as well as alcohol, caffeine, and nicotine must be acknowledged and understood if options for change are to be considered. The resultant cost of recreational drug use as well as health care implications, public safety, and prevention are significant issues society is faced with today. These issues will continue to be significant unless the current posture toward recreational drug use and abuse is addressed. The profession of nursing continues to be faced with the problems associated with recreational drug use not only through caring for clients, but immediately by the effects of recreational drug use on individual professional nurses. To respond effectively, nursing education and nursing research must be challenged to create an emphasis on this focus. Only through this type of multifocal approach will long-term substantial change be affected for the betterment of future generations.

Agricultural and recreational impacts of the conservation reserve program in rural North Dakota, USA.

The Conservation Reserve Program (CRP), created in 1985, provides conservation benefits and agricultural supply control through voluntary, long-term retirement of crop land. While the effects of the CRP on the agricultural sector are well understood, the implications of its conservation benefits for rural economies remain largely undocumented. To quantify the effects on rural economies, this study addressed the net economic effects of decreased agricultural activity and increased recreational activity associated with the CRP in six rural areas of North Dakota from 1996 to 2000. Based on the level of economic activity that would have occurred in the absence of the program, net revenues from CRP land if returned to agricultural production in the six study areas were estimated at $50.2 million annually or $37 per acre of land currently enrolled in the CRP. Recreational (hunting) revenues as a result of the CRP in the study areas were estimated at $12.8 million annually or $9.45 per CRP-acre. The net economic effect of the CRP (lost agricultural revenues and gains in recreational expenditures) indicated that several areas of the state are not as economically burdened by the CRP as previous research has suggested. In addition, the net economic effects of the program would appear more favourable if revenues from all CRP-based recreation were included. The degree that recreational revenues offset agricultural losses might be further enhanced by enterprises that capitalize on the economic opportunities associated with expanded recreational activities on CRP lands.
