“…Some authors found no correlation (18,19); one study (20) found that the prevalence of both chronic and non-chronic fatigue decreases with age; others found a positive correlation (1,12,21,22). The results from the Danish population study among a random sample of 16-77-year-olds (17) may explain the ambiguity in this research.…”

“…Several studies show that low physical activity is related to fatigue (48,158) and to onset of fatigue (18,22,136). Some of the already described studies have actually adjusted the associations between fatigue and adverse outcomes by sleep (62), medications (59) and physical activity (33,62), without attenuation of results.…”

“…It is just as probable for physical inactivity to cause fatigue as it is for fatigue to cause physical inactivity. The cross-sectional nature of fatigue and physical activity does not permit an unequivocal statement about the cause-effect relationship (Chen, 1986). Fatigue can be one effect of muscle atrophy depending on physical inactivity, but the loss of muscle tissue may as well be a result of physical inactivity that is caused by fatigue.…”

Although fatigue is a prevalent and distressing symptom in patients with chronic heart failure (CHF), it is an underestimated problem in the care of patients, and consequently, insuffi ciently investigated. The primary aim of this thesis was, therefore, to advance the knowledge from the patients' perspective by describing characteristics of the fatigue experience and its consequences in daily life in patients with CHF. A secondary aim was to investigate the relationships between fatigue and selected physiological and psychological factors associated with fatigue. Both quantitative and qualitative methods have been used and three samples of patients have been interviewed on different occasions. In two of the quantitative studies 93 patients, and in another study 112 patients, consecutively included, were interviewed at the hospital. Fifteen patients were included in the qualitative study. These 15 participants were enrolled when they visited an outpatient clinic and most of them were interviewed in their homes. These interviews were supplemented with the content of an Internet discussion with persons living with CHF.The results of the studies indicated that fatigue embraces the individual's body, emotions and cognitive abilities, forcing the person to physical restrictions that, in turn, perpetuate emotional discomfort. However, the physical sensation of fatigue followed by functional limitations seemed to be the most prevalent and distressing experience in patients with CHF. The patients described fatigue as lacking strength, which was associated in connection with physical efforts and lacking energy, viewed as an annoying sensation after both mental and physical strain. Another dimension of fatigue was described as being sleepy, often with a rapid and unforeseen onset. Consequences of fatigue, such as refraining from daily chores, denying oneself opportunities for rejoice and social isolation, further exaggerated the experience of fatigue. Restorative activities that engaged, absorbed or distracted the patients counteracted these negative consequences. Depressed mood was related to those fatigue dimensions that compromised functional ability and motivation to start any activities, whereas anxiety was associated with cognitive impairment. Feelings of uncertainty were related to physical tiredness, possibly infl icted by limitations in performing activities. Symptom distress that was caused by a number of reported symptoms other than fatigue had a diminutive infl uence on fatigue and separate symptoms that were associated with fatigue were, with the exception of breathlessness, not the fi rst and most pressing symptom reported by the patients. Anemic patients reported more fatigue compared with non-anemic patients and functional status, according to the New York Heart Association (NYHA) functional classifi cation criteria, was associated with those fatigue dimensions that encompassed physical tiredness and reduced functioning.The fi ndings provide new insights on the characteristics of fatigue and its con...

SUMMARYThis study investigated the variation in perceived tiredness among 11, 13 and 15-yearold Finnish adolescents (n=4187). Additionally interrelationships between sleep habits, use of psychoactive substances (alcohol, tobacco and coffee) and perceived tiredness among 15-year-olds were examined. This study is part of an international, WHOcoordinated survey of school children's health and lifestyle (the HBSC Study). In Finland, research data represented the whole country. The data were collected in March-May 1994. Pupils responded anonymously to a standardized questionnaire during a class period. Subjective tiredness was very common and increased with age among adolescents. Perceived tiredness on at least four school mornings a week increased from 24 to 35% among boys and from 16 to 34% among girls. Feeling tired more often than once a week increased from 20 to 37% in girls and from 24 to 50% in boys. Structural equation models showed that interrelationships between three factors -sleep habits, use of psychoactive substances and perceived tiredness -were statistically significant. For these three factors the two remaining factors explained 24% of the variance of perceived tiredness among boys and 20% among girls, and the two remaining factors explained 42% (16%) of the variation in sleep habits. For the variance of the use of psychoactive substances sleep habits and perceived tiredness explained 26% (12%). Subjective tiredness is strongly age related; this together with the use of psychoactive substances and sleep habits regulate adolescents' daily life and well-being.
