Geographical and socioeconomic distribution of physical activity at work and leisure time and its relation to morbidity in a Swedish rural county.

The article is an account of physical activity at work and during leisure time in a Swedish rural county based on a cross-sectional study of a selection of 7986 individuals in the age range 25-75, at 5-year intervals. 70% of the men and 71% of the women participated in the study--carried out in the spring of 1977--comprising a health examination and a combined inquiry/interview poll. 50% of the men and 22% of the women perform either moderately heavy or heavy work, with little variation between age groups. 20% of the men and 8% of the women engage in regular physical exercise and hard training. 14% of the men and 15% of the women are inactive during their leisure hours. Physical activity at work and physical exercise habits vary in different municipalities. Thus in the rural districts, physical activity at work is greater than elsewhere. Any differences between municipalities disappeared after adjustment for age, sex and occupation. Greater physical activity at work is positively correlated to somatic disturbances, one being a high diastolic blood pressure. A high level of physical activity in leisure time is correlated to low total morbidity of somatic disorders and fewer mental disturbances--irrespective of age, sex, physical activity at work and socioeconomic group. An astonishing finding is that there is no correlation between physical activity during leisure time and at work. Nevertheless, there are differences between socioeconomic groups regarding physical activity during leisure hours. Civil servants are those characterized as most active.

Associations of health-related behaviors, school type and health status to physical activity patterns in 16 year old boys and girls.

Sedentary behavior often begins in childhood and is associated with the development of risk factors for many chronic diseases in adulthood. Physical activity is considered important in the prevention of unfavorable changes in the risk factors. We investigated whether health-related behaviors, school type and health status are associated to physical activity among adolescents. A questionnaire was sent to all Finnish 16-year-old twins in 1991-93. A total of 3,254 twins responded. The response rate was 88%. Physical activity was classified into five categories (very active, active, moderately active, hardly active, inactive) based on self-reported frequency and intensity of physical activity. The analysis considered all subjects as individuals. Smoking was strongly associated with physical activity among girls and boys. Those who smoked regularly were less active. The type of school was also associated with physical activity. In general, those who attended comprehensive school or high school were physically more active, while those in vocational schools, particularly boys, were less active. Girls in lower physical activity groups reported more psychosomatic symptoms. Associations of self-reported health-related behaviors, school type and health status to physical activity seem to be the same among boys and girls. However, as the more active students are in comprehensive school or high school and the less active in vocational school, and physical inactivity is related to smoking and use of alcohol, health education should be tailored by school type.

A description of physical therapists' knowledge in managing musculoskeletal conditions.

BACKGROUND: Physical therapists increasingly provide direct access services to patients with musculoskeletal conditions, and growing evidence supports the cost-effectiveness of this mode of healthcare delivery. However, further evidence is needed to determine if physical therapists have the requisite knowledge necessary to manage musculoskeletal conditions. Therefore, the purpose of this study was to describe physical therapists' knowledge in managing musculoskeletal conditions. METHODS: This study utilized a cross-sectional design in which 174 physical therapist students from randomly selected educational programs and 182 experienced physical therapists completed a standardized examination assessing knowledge in managing musculoskeletal conditions. This same examination has been previously been used to assess knowledge in musculoskeletal medicine among medical students, physician interns and residents, and across a variety of physician specialties. RESULTS: Experienced physical therapists had higher levels of knowledge in managing musculoskeletal conditions than medical students, physician interns and residents, and all physician specialists except for orthopaedists. Physical therapist students enrolled in doctoral degree educational programs achieved significantly higher scores than their peers enrolled in master's degree programs. Furthermore, experienced physical therapists who were board-certified in orthopaedic or sports physical therapy achieved significantly higher scores and passing rates than their non board-certified colleagues. CONCLUSION: The results of this study may have implications for health and public policy decisions regarding the suitability of utilizing physical therapists to provide direct access care for patients with musculoskeletal conditions.

Physical activity as a substitute for sedentary behavior in youth.

BACKGROUND: Youth may choose to be sedentary rather than physically active. PURPOSE: The purpose of this study was to use behavioral economics methods to investigate how experimental changes in the amount of sedentary behaviors influenced physical activity. METHODS: Fifty-eight 8- to 16-year-old youth were studied in a within-subject crossover design with three 3-week phases: baseline, increasing, and decreasing targeted sedentary behaviors by 25% to 50%. RESULTS: At baseline, boys were more active than girls (518.9 vs. 401.2 accelerometer counts/min, p = .02), and obese youth more sedentary than nonobese youth (240.5 vs. 174.4 min/day, p = .003). During the increase sedentary behavior phase, targeted sedentary behaviors increased by 52.1%, with girls increasing sedentary behaviors more than boys (114.7 vs. 79.8 min/day, p = .04). Physical activity decreased (-48.3 counts/min, p < .01) when sedentary behaviors increased, with obese youth decreasing total and moderate to vigorous physical activity (MVPA) more than nonobese youth (-110.4 vs. 8.9 counts/min, p < .001; -3.3 vs. -.03 % MVPA, p = .013). During the decrease sedentary behavior phase, targeted sedentary behaviors decreased by 55.6% from baseline as nonobese youth increased physical activity, whereas obese youth decreased physical activity (55.8 vs. -48.0 counts/min, p = .042; 1.1 vs. -2.1% MVPA, p = .021). Youth who substituted physical activity when sedentary behaviors were increased had greater standardized body mass index (z-body mass index = 1.4 vs. 0.4, p = .018), whereas youth who substituted physical activity when sedentary behaviors were decreased were less active at baseline (396.1 vs. 513.7 counts/min, p = .035). CONCLUSIONS: Behavioral economics provides a methodology to understand changes in physical activity when sedentary behaviors are modified and to identify factors associated with substitution of physically active for sedentary behaviors.

[The relationship of quality of life (QOL) with physical fitness, competence and stress response in elderly in Japan].

OBJECTIVES: In order to evaluate the relationship of quality of life (QOL) with physical fitness, competence and stress response in the elderly population in Japan, a cross sectional field survey of elderly subjects was conducted. METHODS: This survey was taken in Naguri village, Saitama. The data collected included physical fitness, competence, stress response and QOL in addition to demographic variables. As for physical fitness indexes, grip strength (GS), single leg balance with eyes closed (SLB), bar grip ping reaction time (RT), trunk flexion (RF), ten-meter walking time (WT) and vital capacity (VC) were measured. The SF-36 was used for QOL assessment. RESULTS: A total of 120 elderly subjected participated to the survey. There were 42 males (73.5 +/- 5.74 years) and 78 females (74.2 +/- 6.17 years). The associations between physical health parameters in SF-36 and WT were highly significant: physical functioning (beta = -2.96, p < 0.001), role physical (beta = -3.64, p < 0.001), bodily pain (beta = -3.27, p < 0.001) and general health (beta = -3.14, p = 0.001). Psychological stress response had a negative correlation with social functioning (beta = -0.74, p = 0.024), role-emotional (beta = -2.34, p < 0.007) and mental health (beta = -0.97, p = 0.024) as determined by multiple regression analysis. The goodness-of-fit indexes of the structural equation model describing the relationships among physical fitness, competence, stress response and QOL indicated excellent fit to the data with GFI = 0.95 and AGFI = 0.88. Stress response showed relatively stronger influence on QOL than physical fitness or competence. CONCLUSION: Although there were slight differences in degree of influence, physical fitness, stress response and competence were found to be clearly related to QOL in elderly subjects. To keep good QOL status, it is important to maintain good physical fitness and level of competence and to reduce stress response.

The physical activity patterns of European youth with reference to methods of assessment.

This article reviews the habitual physical activity of children and adolescents from member countries of the European Union in relation to methods of assessing and interpreting physical activity. Data are available from all European Union countries except Luxembourg and the trends are very similar. European boys of all ages participate in more physical activity than European girls and the gender difference is more marked when vigorous activity is considered. The physical activity levels of both genders are higher during childhood and decline as young people move through their teen years. Physical activity patterns are sporadic and sustained periods of moderate or vigorous physical activity are seldom achieved by many European children and adolescents. Expert committees have produced guidelines for health-related physical activity for youth but they are evidence-informed rather than evidence-based and where there is evidence of a relationship between physical activity during youth and health status there is little evidence of a particular shape of that relationship. The number of children who experience physical activity of the duration, frequency and intensity recommended by expert committees decreases with age but accurate estimates of how many girls and boys are inactive are clouded by methodological problems. If additional insights into the promotion of health through habitual physical activity during youth are to be made, methods of assessment need to be further refined and recommended guidelines re-visited in relation to the existing evidence base.

Female pelvic organ prolapse: diagnostic contribution of dynamic cystoproctography and comparison with physical examination.

OBJECTIVE: The aim of this study was to assess the contribution of dynamic cystoproctography to the evaluation of female pelvic organ prolapse and to compare this contribution with that of physical examination. MATERIALS AND METHODS: The presence or absence of rectocele, enterocele, sigmoidocele, and cystocele on physical examination and on cystoproctography was retrospectively analyzed in 170 consecutive patients. For each of these diagnostic methods, organ prolapse was graded as small, moderate, or large on the basis of specific, defined measurements. RESULTS: A rectocele was detected by proctography in 155 patients (91%); 119 (77%) of these rectoceles were also found on physical examination. Barium trapping at proctography was related to rectocele size. Proctography showed an enterocele in 47 patients (28%); 24 (51%) of these enteroceles were also found on physical examination. Physical examination also found 44 enteroceles that could not be corroborated radiologically. At proctography, the enteroceles were relatively large, extending an average of 7.3 cm below the vaginal apex. Eight patients had sigmoidoceles, none of which were found on physical examination. A cystocele was shown by cystoproctography in 159 patients (94%); 132 (83%) of these cystoceles were also found on physical examination. CONCLUSION: The correlation between finding prolapsed pelvic organs on dynamic cystoproctography and finding them on physical examination varies. Most radiographically detected rectoceles and cystoceles are found on physical examination, whereas the correlation for enteroceles and sigmoidoceles is poor. Dynamic cystoproctography provides direct visualization and quantification of female pelvic organ prolapse, information that usually can only be inferred by physical examination.

Adiposity compared with physical inactivity and risk of type 2 diabetes in women.

OBJECTIVE: The relative contribution of adiposity and physical inactivity to the risk of developing type 2 diabetes remains controversial. RESEARCH DESIGN AND METHODS: We prospectively examined the individual and joint association of obesity and physical activity with the development of type 2 diabetes in 68,907 female nurses who had no history of diabetes, cardiovascular disease, or cancer at baseline. Adiposity was measured by BMI and waist circumference. Physical activity was assessed through average hours of moderate or vigorous exercise and computation of an MET score. RESULTS: We documented 4,030 incident cases of type 2 diabetes during 16 years of follow-up (from 1986 to 2002). In a multivariate model including age, smoking, and other diabetes risk factors, risk of type 2 diabetes increased progressively with increasing BMI (P < 0.001) and waist circumference (P < 0.001) and with decreasing physical activity levels (P < 0.001). In joint analyses of BMI and physical activity, using women who had a healthy weight (BMI < 25 kg/m(2)) and were physically active (exercise > or = 21.8 MET h/week) as the reference group, the relative risks of type 2 diabetes were 16.75 (95% CI 13.99-20.04) for women who were obese (BMI > or = 30 kg/m(2)) and inactive (exercise < 2.1 MET h/week), 10.74 (8.74-13.18) for women who were active but obese, and 2.08 (1.66-2.61) for women who were lean but inactive. In combined analyses of waist circumference and physical activity, both variables were significant predictors of type 2 diabetes, but the association for waist circumference was substantially stronger than that for physical inactivity. CONCLUSIONS: Obesity and physical inactivity independently contribute to the development of type 2 diabetes; however, the magnitude of risk contributed by obesity is much greater than that imparted by lack of physical activity.

Relating trait anxiety to perceived physical fitness.

This study was designed to determine the relation of actual cardiovascular physical fitness and perceived physical fitness to trait anxiety. 32 older adult (M age = 68.19 yr.) subjects completed a voluntary maximal graded exercise stress test on a motor driven treadmill to determine their actual cardiovascular physical fitness. Subjects also completed Abadie's Perceived Physical Fitness Scale along with Spielberger's Trait Anxiety Inventory. The partial correlation between actual cardiovascular physical fitness and trait anxiety with the influence of perceived physical fitness removed indicated a nonsignificant relation. The partial correlation between perceived physical fitness and trait anxiety with the influence of actual cardiovascular physical fitness removed indicated a significant inverse relation. Present results suggest that trait anxiety is correlated better with an individual's self-perception of his physical fitness than the actual cardiovascular physical fitness.

[Are children and adolescents less physically active today than in the past?].

In recent years it has been claimed that Norwegian children and youth have reduced their level of physical activity and fitness. The aim of this systematic review was to investigate whether the amount of physical activity or level of physical fitness have changed among Norwegian children and youth during the past decades. We searched for relevant information in databases and reference lists and established contacts with scientists working in this field. The quality of the studies was evaluated on the basis of selection bias, information bias and adequate reporting of results. Five repeated cross-sectional studies of healthy boys and girls in the period from 1950 to 1997 were included. Three are based on tests of physical fitness and two of self-reported physical activity. The studies indicate that the physical fitness of the older boys has been reduced, the level of activity has been lowered, the percentage of inactive youth has increased and there are now larger variations in physical fitness. We conclude that there seems to be a negative trend in the level of physical fitness and physical activity of children and youth. This shows the need for interventions. The need for standardised parameters for physical activity is apparent.

Perceptions of nurse practitioners regarding their role in physical activity and exercise prescription for older adults.

Health promotion related to physical activity and exercise is an integral part of the nurse practitioner (NP) role. Yet, studies suggest that only 30% of primary care clinicians provide counseling to their sedentary patients (Clinician's Handbook of Preventive Services, 1994). This percentage may be even less with clients who represent the oldest old or a minority population. Information about the extent to which NPs counsel patients about physical activity and exercise prescription has not been well documented. The purpose of this research study was to identify the NPs role in providing individualized exercise prescription and to determine what strategies NPs use in assisting older adults to initiate and maintain an exercise program. The study utilized a focus group design comprising two focus groups, ranging in size from 6 to 7. Purposive sampling was used to enlist NP focus group participants. Content analysis of each transcript revealed that NP participants in these two focus groups utilize health history taking and observation skills in determining an older adult's physical fitness, physical activity, and exercise. None of the NP participants used a formalized instrument, nor did they use specific guidelines in prescribing physical activity and exercise recommendations. Frailty and socioeconomic status were variables that NPs consider in their physical activity and exercise recommendations, whereas ethnicity, age, and gender were not. Overall, NPs reported using a very small percentage of their time to physical activity and exercise counseling in primary care visits. Given the well-documented benefits of physical activity and exercise (U.S. Department of Health and Human Services, 1996; American College of Sports Medicine, 1998), it remains a matter of serious concern that more than 60% of American adults are not regularly physically active (Office of the Surgeon General, 1996). It is imperative that policymakers include physical activity and exercise counseling as a condition for reimbursement in primary care visits.

[Amount and intensity of physical exercise in primary prevention].

Numerous epidemiological studies have demonstrated an inverse relation between physical activity and physical "fitness" on one hand and premature death and the risk of chronic disease on the other hand. However, most of these studies showed crucial methodological and statistical differences, a fact which caused a lack of consensus of dose and intensity of physical activities for "health benefits". The optimal amount of physical activity to decrease mortality is in literature stated to range between 1,000 and 3,500 motoric kcal per week. Only a few data exist concerning the optimal intensity of preventive physical activities. There is some indication that only "vigorous" but not "non-vigorous" physical activities are associated with decreased mortality. Previous investigations suggest that a "threshold-intensity" (e.g. of at least 6 MET of "conditioning physical activity") is needed to produce an adequate preventive effect. On the other hand it has been documented, that "physical fitness" (endurance capacity) is a decisive factor for a decreased mortality. Therefore it may be assumed, that physical activities are only efficient for health benefits, if they also result in increased physical fitness. Following from this assumption the quality and quantity of training in primary prevention has to be adjusted to the individual requirements (performance, age, gender, health) of men.

[Physical activity for the elderly].

UNLABELLED: Prolongation of life expectancy requires inevitable care for the quality of life of the elderly. Regular physical activity has a very important role in preserving the quality of life and independence, and not only reducing illness and mortality. A better understanding of this issue should enable us to set guidelines for regular physical activity for the elderly. The reaction to regular physical activity of older adults without cardiovascular diseases is similar to the reaction of young people to regular physical activity. In men, the mechanism of cardiovascular adaptation is mainly central, while in old women it is mainly peripheral. Elderly with cardiovascular diseases suffer from oxygen consumption and cardiac output reduction, compared to healthy old people. They also enjoy the cardiovascular benefits of aerobic physical activity and gain the risk factors profile improvement. Therefore, it is recommended to include aerobic physical activity as an integrative part of the daily lifestyle. Resistance strength training in elderly of both sexes leads to similar or even higher values for muscle mass and strength compared to young people, reduces the body fat mass, body weight and helps to preserve the active tissue mass. More beneficial effects of physical activity are: an improvement of posture and physical stability, improved flexibility and mobility capacity, a better cognitive function and a lower level of depression. The beneficial effects of physical activity in the very aged and frail elderly include physiological, metabolic, psychological and functional adaptations, which can substantially contribute to the quality of life and cannot be achieved by other treatments. SUMMARY: Participation in a regular physical activity program is an effective and secure means to avoid and reduce the functional decline associated with aging and to improve the quality of life. The recommended exercise program is multifactorial and includes aerobic and resistance training, and exercises of balance and flexibility.

Physician ownership of physical therapy services. Effects on charges, utilization, profits, and service characteristics.

OBJECTIVE: To evaluate the effects of physician ownership of freestanding physical therapy and rehabilitation facilities on utilization, charges, profits, and three measures of service characteristics for physical therapy treatments. DESIGN: Statistical comparison by physician joint venture ownership status of freestanding physical therapy and comprehensive rehabilitation facilities providing physical therapy treatments in Florida. PARTICIPANTS: A total of 118 outpatient physical therapy facilities and 63 outpatient comprehensive rehabilitation facilities providing services in Florida during 1989. The data from the facilities were collected under a legislative mandate. MAIN OUTCOME MEASURES: Visits per patient, average revenue per patient, percent operating income, percent markup, profits per patient, licensed therapist time per visit, and licensed and nonlicensed medical worker time per visit. RESULTS: Visits per patient were 39% to 45% higher in joint venture facilities. Both gross and net revenue per patient were 30% to 40% higher in facilities owned by referring physicians. Percent operating income and percent markup were significantly higher in joint venture physical therapy and rehabilitation facilities. Licensed physical therapists and licensed therapist assistants employed in non-joint venture facilities spend about 60% more time per visit treating physical therapy patients than licensed therapists and licensed therapist assistants working in joint venture facilities. Joint ventures also generate more of their revenues from patients with well-paying insurance. CONCLUSION: Our results indicate that utilization, charges per patient, and profits are higher when physical therapy and rehabilitation facilities are owned by referring physicians. With respect to service characteristics, joint venture firms employ proportionately fewer licensed therapists and licensed therapist assistants to perform physical therapy, so that licensed professionals employed in joint venture businesses spend significantly less time per visit treating patients. These results should be of interest to the medical profession, third-party payers, and policymakers, all of whom are concerned about the consequences of physician self-referral arrangements.

Teachers' perspective on barriers to implementing physical activity curriculum guidelines for school children in Toronto.

BACKGROUND: Teachers in Ontario are expected to implement the physical activity guidelines in the health and physical education (HPE) curriculum document that was introduced in 1998. This study examined Toronto teachers' perspective on barriers to implementing these guidelines. METHODS: Forty-five teachers from five Toronto elementary schools in which generalist classroom teachers provide physical education classes participated in focus groups. An experienced moderator facilitated each session. Themes were inductively generated from the data. RESULTS: Participants reported that children were not engaged in moderate or vigorous physical activity daily and for the expected duration. Participants identified three categories of barriers to implementing the curriculum guidelines: lower priority for HPE, lack of performance measures for physical activity, and lack of sufficient infrastructure. First, they reported that the new curriculum expectations for other subjects were demanding, which left little time to focus on physical education. They felt that resource support for the HPE curriculum was not sufficient and that physical education specialists were necessary but unavailable to implement the curriculum. Second, participants felt accountable to both government and parents for high student performance on standardized tests in subjects deemed to be of higher priority. Third, participants reported inadequate facilities and equipment, use of portables for classrooms, cancelling physical education to have events in the gymnasium, and unavailability of teachers to supervise off-school physical activity. CONCLUSION: The study suggests that participating teachers perceive physical education to be a low priority in the educational system, making it difficult for them to meet the HPE curriculum expectations.

The role of health promotion in physical therapy in California, New York, and Tennessee.

BACKGROUND AND PURPOSE: As health care providers, physical therapists are in an ideal position to address health promotion issues with their patients; yet, little is known about actual health promotion practice patterns or the confidence of physical therapists in engaging in such activities. The purposes of this study were: (1) to investigate perceptions of practice patterns in 4 focus areas of Healthy People 2010 (disability and secondary conditions by assessing psychological well-being, nutrition and overweight, physical activity and fitness, and tobacco use) and (2) to identify related self-efficacy and outcome expectations in California, New York, and Tennessee. SUBJECTS: A instrument was pilot tested and distributed in 2 waves to 3,500 randomly selected, licensed physical therapists from 3 states: California, New York, and Tennessee. METHODS: Interviews were randomly conducted via telephone with 23 physical therapists in all 3 states until similar responses were identified in order to create the qualitative instrument, which was then pilot tested with 20 physical therapists in California. The total number of qualitative instruments used in the data analyses was 417 (145 from California, 127 from New York, and 145 from Tennessee) or 11.9%. RESULTS: The health promotion behavior most commonly thought to be practiced by physical therapists was assisting patients to increase physical activity (54%), followed by psychological well-being (41%), nutrition and overweight issues (19%), and smoking cessation (17%). Self-efficacy predicted all 4 behaviors beyond the control variables. Minimal state-to-state differences were noted. DISCUSSION AND CONCLUSION: Physical therapists believe they are addressing health promotion topics with patients, although in varying degrees and in lower than desirable percentages based on Healthy People 2010 goals. This study demonstrated that a physical therapist's confidence in being able to perform a behavior (self-efficacy) was the best predictor of perceptions of practice patterns and is an area to target in future interventions.

[Physical training for nursing home residents--has it any effect?].

BACKGROUND: The paper presents documentation of the effect of physical training for nursing home residents. MATERIAL AND METHODS: Literature study based on review articles and exercise trials in nursing home populations. RESULTS AND INTERPRETATION: The relatively few studies available indicate that physical training in a nursing home setting could be carried out. One study, reporting the effect of a fourfold increase in physiotherapy and occupational therapy, found positive effects on physical functioning and nursing costs. Furthermore, training is reported to improve aspects of physical functioning, like muscle strength and mobility. Several studies report effect on incontinence of low-dose physical exercises combined with scheduled toilet training. No study reports effect of physical training alone on the incidence of falls among nursing home residents. Nevertheless, physical training seems to improve physical fitness and functioning, cognition and behaviour. It is suggested that physical training for nursing home residents is carried out routinely in order to maintain physical functioning. Important aspects of such training are muscle strength, balance, coordination, endurance and flexibility. However, the most crucial type of training is active participation in the activities of daily life in order to prevent loss of independence.

[Degree and dynamics of changes in physical work capacity of children and adolescents in relation to somatic development and motor activity].

The author presents and discusses the problems of work physiology in the age of development and changes of physical performance during the second decade of life on the basis of the results of her own cross-sectional and two series of longitudinal studies. The main considered problems are as follows: Morphological, physiological and psychological determination of adaptation of children and adolescents to physical exercises. The level of aerobic and anaerobic capacity of Warsaw children aged 9-15 years. Cross-sectional study (n = 667); measurements: PWC170 using bicycle ergometer and step test, anaerobic capacity using Wingate Anaerobic Test according to Bar-Or (1978). Dynamics of changes of physical work capacity (PWC170) in children and adolescents 11-17 years old in relation to their physical activity, chronological and biological age--longitudinal studies (n = 112). Dynamics of changes of aerobic capacity (VO2 max--directly measured) in children aged 11-14 years in relation to their chronological, biological age and sport disciplines--longitudinal studies (n = 94). Motor development and reaction to different types of exercises in obese 7-15 years old children. Cross-sectional studies (n = 257); measurements: physical fitness using Denisiuk's, Chromiński's, Ozjerecki's tests; tapping test; some indices of respiratory function; PWC170; haemodynamic reaction on isometric exercise; physical activity and work load during physical education lessons. In conclusion about every above mentioned chapter practical indications for physical education, sports and health care are recommended. The elaborated norms for some indices of aerobic and anaerobic capacity may be useful in individual diagnosis of physical work capacity of healthy and sick children, monitoring its changes during growth as well as in observation of secular changes of physical performance in the future.
