A hypothesis concerning habitual sleep reduction and its adverse consequences among general population in modern societies has received wide publicity in the mass media, although scientific evidence supporting the hypothesis is scarce. Similarly, there is an extensively distributed belief, at least in Finland, that the prevalence of insomnia‐related symptoms is increasing, but evidence for this is even sparser. These issues are important because of the known increased risk of mortality and health risks associated with sleep duration deviating from 7 to 8 h. To reveal possible trends in self‐reported sleep duration and insomnia‐related symptoms, we reanalyzed all available data from surveys carried out in Finland from 1972 to 2005. The main results were that a minor decrease of self‐reported sleep duration has taken place in Finland, especially among working aged men. However, the size of the reduction (about 4%) was relatively small, approximately 5.5 min per each 10 years during the 33 years’ time interval under study. The proportion of 7 h sleepers has increased and, correspondingly, the proportion of 8 h sleepers has decreased, but the extreme ends of the sleep duration distribution remained unchanged. Tentative evidence suggesting an increase in insomnia‐related symptoms among working aged population during the last 10 years was found. In conclusion, the Finnish data during the past 33 years indicate a general decrease in self‐reported sleep duration of about 18 min and an increase of sleep complaints, especially among the employed middle‐aged population.

Health related quality of life among insulin-dependent diabetics: disease-related and psychosocial correlates

Anna-Mari Aalto; Antti Uutela; Arja R. Aro

This crossectional questionnaire study examined the associations of health factors and psychosocial factors with Health Related Quality of Life (HRQOL) in a sample of adult type I diabetic patients (n = 385). Health related quality of life was measured by the Finnish version of MOS SF-20. Psychosocial measures were general social support, diabetes-specific social support, diabetes locus of control (DCL), self-efficacy, diabetes health beliefs and self-care practices. In multivariate analyses, limitations in physical functioning showed strong associations with perceived health (beta = -0.33, P < 0.001), role functioning (OR = 38.54, 95% CL 10.73-139.56), social functioning (OR = 7.05, 95% CL 2.88-17.27) and pain (OR = 7.89, 95% CL 4.26-14.47), and was moderately associated to mental health (beta = -0.12, P < .01). Duration of diabetes and glycemic control were not related to HRQOL dimensions. Adequacy of social support was related to all HRQOL domains apart from pain and role functioning. The most important diabetes-related psychosocial factors were self-efficacy, and diabetes-related social support. Diabetes-specific factors were more important among those in good physical condition.

The aim of this study was to examine psychological distress in a mammography screening process as a consequence of screening after adjusting for background, personality and prescreening distress. Subjects, aged 50 years, were invitees at their first screening. There were three groups; normal findings (n=1407), false-positive findings (n=492) and referents from outside the screening programme (n=1718, age 48-49 years). Distress was measured as illness worry, anxiety, depression, cancer beliefs and early detection behaviour. Measurements were one month before screening invitation with follow-ups at 2 and 12 months postscreening. At 2 months, there was a moderate multivariate effect of group on distress; and intrusive thinking and worry about breast cancer, in particular, were most frequent amongst the false positives. Intrusive thinking still prevailed at 12 months, in addition to a higher perceived breast cancer risk and susceptibility. Distress related to screening and false-positive findings seems to be moderate, but prevailing cancer-specific concerns call for improvements in screening programmes.

Self‐reported short or long sleep duration has been repeatedly found to be associated with increased mortality and health risks. However, there is still an insufficient amount of detailed knowledge available to characterize the short and long sleep duration groups in general population. Consequently, the underlying mechanisms potentially explaining the health risks associated with short and long sleep duration are unclear. In the present study, the self‐reported sleep duration in a sample of Finnish general population was studied, and its possible associations with such factors as self‐perceived health, sociodemographic characteristics, lifestyle, sleep difficulties and daytime concomitants were analyzed. In particular, an effort was made to define mutually statistically‐independent determinants of sleep duration. In the Finnish Health 2000 Survey, a representative sample of 8028 subjects of 30 years of age or older and a sample of 1894 subjects of 18–29 years of age were invited to take part in the health interview and health examination. The participation rate of the study was over 80%. The most important and statistically‐independent determinants of short and long sleep duration were gender, physical tiredness, sleep problems, marital status, main occupation and physical activity. However, in the multivariable model they only accounted for approximately 16% of the variance in sleep duration in short and long sleepers, suggesting multiple sources of variance. The present study also suggests a dose–response like relationship between the sleep duration and many of its determinants within both short and long sleepers. A more detailed analysis of the clinical status of the short and long sleep duration groups is needed to evaluate the possible importance of these findings for health risks associated with sleep duration.

Objective To study psychosocial predictors of attendance at an organised breast cancer screening programme. Setting Finnish screening programme based on personal first round invitations in 1992–94, and with 90% attendance rate. Methods Attenders (n=946) belonged to a 10% random sample (n=1680 women, age 50, response rate 64%) of the target population (n=16 886), non-attenders (n=641, 38%) came from the whole target population. Predictors were measured one month before the screening invitation. Measures included items for social and behavioural factors, Breast Cancer Susceptibility Scale, Illness Attitude Scale, Health Locus of Control Scale, Anxiety Inventory, and Depression Inventory. Univariate and multivariate logistic regression analyses were used to predict attendance. Results Those most likely to attend were working, middle income, and averagely educated women, who had not had a mass mammogram recently, but who regularly visited gynaecologists, attended for Pap smear screening, practised breast self examination, and who did not smoke. Low confidence in their own capabilities in breast cancer prevention, overoptimism about the sensitivity of mammography, and perception of breast cancer risk as moderate were also predictive of attendance. Expectation of pain at mammography was predictive of non-attendance. Conclusion Mammography screening organised as a public health service was well accepted. A recent mammogram, high reliance on self control of breast cancer, and an expectation of pain at mammography deterred attendance at screening. Further information about these factors and health information on screening are needed.

AbstractObjective. To find out reasons for non-attendance and to study subgroup differences of the non-attenders in an organized mammography screening program. Design. Prospective for background and psychosocial factors, retrospective for reasons of non-attendance. Setting. Finnish screening based on personal first round invitations, with 89% attendance rate. Participants. Four hundred thirty six women with both pre-screening response to socioeconomic and psychosocial measures, and post-screening response reporting reasons of non-attendance. Main results. Most common single reason for non-attendance was previous recent mammogram (53%), but also reasons related to practical obstacles, worry and fear, knowledge and attitudes, and organization of screening were mentioned. Two distinct groups of non-attenders were found based on the reasons for non-attendance. Those who did not attend because a mammogram taken elsewhere (ELSE, n = 233) were urban, well-to-do women, who took care of their health by own initiation and felt more susceptible to breast cancer, and also expected mammogram to be painful. Other (real) non-attenders (REAL, n = 155) were less compliant with health recommendations and services, more socially isolated, depressed and anxious than ELSE. Level of depression among REAL was clearly higher (10.80) than the mean value (7.91, SD = 7.28) of the age group, and was also slightly above the cut-off score of 10 indicating mild or moderate depression. Trait anxiety was also markedly higher (40.18) than that of the same age group (37.76, SD = 8.95). Conclusions. Further research should clarify determinants and consequences of depression and anxiety among real non-attenders. Knowledge gaps and attitudinal barriers among non-attenders require more targeted campaigns.

BACKGROUND AND AIM OF THE STUDY The aim of this study is to report the prevalence of menopausal symptoms by severity among the Finnish female population and the association of their symptoms with lifestyle (smoking, use of alcohol, physical activity) and body mass index (BMI). MATERIAL AND METHODS Health 2000 is a nationally representative population-based study of Finnish adults. Data were collected by home interview, three self-administered questionnaires and a clinical examination by a physician. This study included women aged 45-64 years (n=1427). All symptoms included menopause-specific symptoms. Both univariate analysis and a factor analysis based on symptom factors were performed by menopausal group. Multiple regression analysis included each symptom factor as a dependent variable and confounding and lifestyle factors (age, education, smoking, alcohol use, physical activity, BMI, use of hormonal replacement therapy (HRT) and chronic disease status). RESULTS Over one-third (38%) of the premenopausal, half of the perimenopausal, and 54% of both postmenopausal and hysterectomized women reported bothersome symptoms. The difference between pre- and perimenopausal women was largest and statistically most significant in the case of back pain and hot flushes. Physically active women reported fewer somatic symptoms than did women with a sedentary lifestyle. Smoking was not related to vasomotor symptoms. CONCLUSION Bothersome symptoms are common in midlife, regardless of menopausal status. Inverse association between physical activity and menopausal symptoms needs to be confirmed in randomized trials.

During autumn 2005, we conducted 3,436 interviews in European and Asian countries. We found risk perceptions of avian influenza to be at an intermediate level and beliefs of efficacy to be slightly lower. Risk perceptions were higher in Asia than Europe; efficacy beliefs were lower in Europe than Asia.

Risk Perceptions Related to SARS and Avian Influenza: Theoretical Foundations of Current Empirical Research

Anja Leppin; Arja R. Aro

BackgroundThe outbreak of severe acute respiratory syndrome in 2003 and the subsequent emergence of the H5N1 virus have highlighted the threat of a global pandemic influenza outbreak. Planning effective public health control measures for such a case will be highly dependent on sound theory-based research on how people perceive the risks involved in such an event.PurposeThe present article aims to review theoretical models and concepts underlying current empirical research on pandemic influenza risk perception.MethodA review was conducted based on 28 empirical studies from 30 articles which were published between 2003 and 2007.ResultsConcepts of risk perception mostly seemed more pragmatic than theory-based and were highly heterogeneous, for instance, in terms of conceptualizing risk perception as an exclusively cognitive or as a cognitive and emotional phenomenon or whether the concept was dominated by expectancy or expectancy and value components. Similarly, the majority of studies investigating risk perceptions and protective behaviors were not model-based.ConclusionsThe current body of knowledge can only provide preliminary insights. Unlike the reviewed studies, which were mostly launched as a rapid response to outbreak situations, future research will have to invest more strongly into theoretical work to provide sounder evidence.

Johannes Brug; Arja R. Aro; Anke Oenema; Onno de Zwart; Jan Hendrik Richardus; George D. Bishop

Severe acute respiratory syndrome (SARS)–related risk perceptions, knowledge, precautionary actions, and information sources were studied in the Netherlands during the 2003 SARS outbreak. Although respondents were highly aware of the SARS outbreak, the outbreak did not result in unnecessary precautionary actions or fears.
