Health check documentation of psychosocial factors using the WAI.

BACKGROUND: Health checks in occupational health (OH) care should prevent deterioration of work ability and promote well-being at work. Documentation of health checks should reflect and support continuity of prevention and practice. AIMS: To analyse how OH nurses (OHNs) undertaking health checks document psychosocial factors at work and use the Work Ability Index (WAI). METHODS: Analysis of two consecutive OHN health check records and WAI scores with statistical analyses and annotations of 13 psychosocial factors based on a publicly available standard on psychosocial risk management: British Standards Institution specification PAS 1010, part of European Council Directive 89/391/EEC, with a special focus on work-related stress and workplace violence. RESULTS: We analysed health check records for 196 employees. The most frequently documented psychosocial risk factors were home-work interface, work environment and equipment, job content, workload and work pace and work schedule. The correlations between the number of documented risk and non-risk factors and WAI scores were significant: OHNs documented more risk factors in employees with lower WAI scores. However, documented psychosocial risk factors were not followed up, and the OHNs' most common response to detected psychosocial risks was an appointment with a physician. CONCLUSIONS: The number of psychosocial risk factors documented by OHNs correlated with subjects' WAI scores. However, the documentation was not systematic and the interventions were not always relevant. OHNs need a structure to document psychosocial factors and more guidance in how to use the documentation as a tool in their decision making in health checks.

Cardiovascular health in former elite male athletes.

To increase our knowledge on the effects of previous and current physical activity on cardiovascular health, we studied a group of Finnish male former elite athletes (endurance, n = 49; power, n = 50) and their 49 age and area-matched controls, aged 64-89 years. Body mass index (BMI), fasting serum glucose, lipids, blood pressure, and ultrasonography of cardiac and carotid artery structure and function were measured. Former endurance athletes smoked less, had lower prevalence of hypertension, and had higher intensity and volume of leisure time physical activity (LTPA) than the controls. No difference was detected in cardiac or carotid artery structure and function between these groups. Former athletes performing high-intensity LTPA were slightly younger (possible selection bias), had lower BMI and waist circumference, lower use of antihypertensives, lower prevalence of diabetes, lower pulse wave velocity, and higher carotid artery elasticity than former athletes not performing high-intensity LTPA. In conclusion, former athletes had a higher intensity and volume of LTPA than the controls. Athletes performing vigorous LTPA had more elastic arteries than athletes performing moderately or no LTPA. Vigorous LTPA through the whole lifetime associates with good cardiovascular health, although the previous medical history may play an important role.

No increase in the prevalence of COPD in two decades.

Relevant information on the prevalence of chronic obstructive pulmonary disease (COPD) and its trends is scarce. In the present study, we compare the prevalence rates and potential determinants of COPD in two national population samples that were surveyed 20 yrs apart. In 1978-1980, a sample of 8,000 people was surveyed; subjects were representative of the Finnish population and were aged ≥30 yrs. Among those aged 30-74 yrs, acceptable spirometry was obtained from 6,364 (87%) subjects. In a similar survey conducted in 2000-2001, comparable spirometry was obtained from 5,495 (80%) participants. Airway obstruction was defined as forced expiratory volume in 1 s (FEV(1))/forced vital capacity below the lower limit of normal and staged for severity on the basis of FEV(1) % predicted. The age-adjusted prevalence rates of obstruction (stages I-IV) were rather similar in both surveys in males (4.7 versus 4.3%; p = 0.25), but were almost significantly higher in females in the later survey (2.2 versus 3.1%; p = 0.06). The rates of COPD stage II or higher were 3.9% in 1978-1980, and 3.6% in 2000-2001 (p = 0.36) for males, and 1.4 and 1.5% (p = 0.93), respectively, for females. In conclusion, no significant difference was found in the prevalence of COPD stages II-IV between similar population based surveys performed 20 yrs apart. Since COPD is mostly mild or moderate there is a strong case for early prevention.

The association between team climate at work and mental health in the Finnish Health 2000 Study.

OBJECTIVES: Depression, anxiety and alcohol use disorders are common mental health problems in the working population. However, the team climate at work related to these disorders has not been studied using standardised interview methods and it is not known whether poor team climate predicts antidepressant use. This study investigated whether team climate at work was associated with DSM-IV depressive, anxiety and alcohol use disorders and subsequent antidepressant medication in a random sample of Finnish employees. METHODS: The nationally representative sample comprised 3347 employees aged 30-64 years. Team climate was measured with a self-assessment scale. Diagnoses of depressive, anxiety and alcohol use disorders were based on the Composite International Diagnostic Interview. Data on the purchase of antidepressant medication in a 3-year follow-up period were collected from a nationwide pharmaceutical register of the Social Insurance Institution. RESULTS: In the risk factor adjusted models, poor team climate at work was significantly associated with depressive disorders (OR 1.61, 95% CI 1.10 to 2.36) but not with alcohol use disorders. The significance of the association between team climate and anxiety disorders disappeared when the model was adjusted for job control and job demands. Poor team climate also predicted antidepressant medication (OR 1.53, 95% CI 1.02 to 2.30). CONCLUSION: A poor team climate at work is associated with depressive disorders and subsequent antidepressant use.

Fatigue in multiple sclerosis patients during inpatient rehabilitation.

PURPOSE: This study was designed to evaluate symptomatic fatigue in patients with mild to moderate multiple sclerosis (MS) during inpatient rehabilitation. We examined fatigue at the beginning and at the end of a 3-week rehabilitation period as well as its daily variation. METHOD: Ninety-one patients participated. Fatigue severity was measured using the Fatigue Severity Scale (FSS). On the basis of the FSS scores, patients were divided into a fatigue (n = 66) and non-fatigue (n = 25) group. General fatigue was self-evaluated using a Visual Analogue Scale (FVAS). Depression was measured using The Centre for Epidemiologic Studies Depression scale (CES-D). RESULTS: In the fatigue group the mean FSS score decreased by 0.34 points, whereas in the non-fatigue group it increased by 0.23 points. The difference for change between groups was significant (p = 0.003), but a covariate analysis showed that this was strongly affected by a decrease in depression. Fatigue varied greatly from day-to-day. The lowest FVAS coefficient of variation per patient was 9% and the highest 131%. CONCLUSION: Inpatient rehabilitation decreases MS patients' fatigue. This effect seems to be modified by an improvement in mood.

Cardiac interbeat interval dynamics from childhood to senescence : comparison of conventional and new measures based on fractals and chaos theory.

BACKGROUND: New methods of R-R interval variability based on fractal scaling and nonlinear dynamics ("chaos theory") may give new insights into heart rate dynamics. The aims of this study were to (1) systematically characterize and quantify the effects of aging from early childhood to advanced age on 24-hour heart rate dynamics in healthy subjects; (2) compare age-related changes in conventional time- and frequency-domain measures with changes in newly derived measures based on fractal scaling and complexity (chaos) theory; and (3) further test the hypothesis that there is loss of complexity and altered fractal scaling of heart rate dynamics with advanced age. METHODS AND RESULTS: The relationship between age and cardiac interbeat (R-R) interval dynamics from childhood to senescence was studied in 114 healthy subjects (age range, 1 to 82 years) by measurement of the slope, beta, of the power-law regression line (log power-log frequency) of R-R interval variability (10(-4) to 10(-2) Hz), approximate entropy (ApEn), short-term (alpha(1)) and intermediate-term (alpha(2)) fractal scaling exponents obtained by detrended fluctuation analysis, and traditional time- and frequency-domain measures from 24-hour ECG recordings. Compared with young adults (<40 years old, n=29), children (<15 years old, n=27) showed similar complexity (ApEn) and fractal correlation properties (alpha(1), alpha(2), beta) of R-R interval dynamics despite lower spectral and time-domain measures. Progressive loss of complexity (decreased ApEn, r=-0.69, P<0.001) and alterations of long-term fractal-like heart rate behavior (increased alpha(2), r=0.63, decreased beta, r=-0.60, P<0.001 for both) were observed thereafter from middle age (40 to 60 years, n=29) to old age (>60 years, n=29). CONCLUSIONS: Cardiac interbeat interval dynamics change markedly from childhood to old age in healthy subjects. Children show complexity and fractal correlation properties of R-R interval time series comparable to those of young adults, despite lower overall heart rate variability. Healthy aging is associated with R-R interval dynamics showing higher regularity and altered fractal scaling consistent with a loss of complex variability.

Smoking is independently associated with high plasma insulin levels in nondiabetic men.

OBJECTIVE: Studies using the euglycemic clamp technique or the insulin suppression test in relatively small numbers of subjects have suggested that smoking may cause insulin resistance. Our aim was to study the association between smoking status and fasting plasma insulin in a large nondiabetic male population. RESEARCH DESIGN AND METHODS: A total of 616 nondiabetic men aged 45-64 years were taken from a population register. Fasting plasma insulin and blood pressure were measured, and smoking history and medication were evaluated by interview. RESULTS: Age- and BMI-adjusted insulin levels were significantly higher in smokers and ex-smokers than in nonsmokers (92.4, 86.4, and 78.6 pmol/l, respectively; P = 0.009). In every BMI-tertile, smokers and ex-smokers had higher plasma insulin than nonsmokers. After adjustment for factors potentially affecting insulin sensitivity (hypertension, systolic or diastolic blood pressure, use of beta-blockers and/or diuretics, use of vasodilating antihypertensive drugs, physical exercise, alcohol use, parental history of NIDDM, coronary heart disease, and previous myocardial infarction), insulin concentrations were still highest in smokers (91.2 pmol/l), intermediate in ex-smokers (86.8 pmol/l), and lowest in nonsmokers (78.9 pmol/l, P = 0.008 between groups). CONCLUSIONS: Our results show that chronic smoking is associated with high age- and BMI-adjusted plasma insulin levels, independent of other factors known to influence insulin sensitivity. The effect of smoking may be partially reversible after quitting.

Bone mineral density in patients with type 1 and type 2 diabetes.

OBJECTIVE: To assess the effect of type 1 and type 2 diabetes and insulin treatment on bone mineral density (BMD) in middle-aged and elderly men and women. RESEARCH DESIGN AND METHODS: We measured BMD and evaluated known determinants of osteoporosis in 56 type 1 and 68 type 2 diabetic patients and 498 nondiabetic community control subjects. All patients, aged 52-72 years, developed diabetes after the age of 30 years (i.e., after achievement of peak bone mass) and were treated with insulin. BMD was measured at the proximal femur with dual-energy X-ray absorptiometry. RESULTS: Among both sexes, BMD values were significantly lower in type 1 diabetic patients than in type 2 diabetic patients or the control subjects. When adjusted for age and BMI, the differences between type 1 diabetic patients and control subjects remained essentially unchanged in both sexes, whereas the differences between type 1 and type 2 diabetic subjects were significant only in men. After further adjustments for confounding factors, the average BMD values were still lower in type 1 diabetic subjects than in type 2 diabetic subjects although with lesser significance. Past low-energy fractures were more common in type 1 diabetic women than in type 2 diabetic women. CONCLUSIONS: The lower BMD in type 1 versus type 2 diabetic patients and control subjects probably results from more rapid bone loss after the onset of type 1 diabetes. This cannot be explained by insulin treatment, which was prescribed for both types of patients. Because the causes of low BMD in type 1 diabetes are unknown, these patients should be evaluated for the risk of osteoporosis and related fractures and offered appropriate preventive measures.

Atherosclerotic vascular disease and its risk factors in non-insulin-dependent diabetic and nondiabetic subjects in Finland.

A cross-sectional study on the prevalence of atherosclerotic vascular disease (ASVD) and its risk factors in non-insulin-dependent diabetic and nondiabetic subjects was carried out from 1982 to 1984 in East Finland (Kuopio) and West Finland (Turku), two areas known to differ markedly in prevalence of ASVD in the nondiabetic population. A total of 510 diabetic and 649 nondiabetic subjects aged 45-64 yr were examined in East Finland and 549 diabetic and 724 nondiabetic subjects of the same age in West Finland. In both areas and in both sexes the prevalence of coronary heart disease (CHD), stroke, and intermittent claudication was higher in diabetic than in nondiabetic subjects. Both in diabetic and nondiabetic subjects the prevalence of ASVD was higher in East Finland than in West Finland. In men, the East-West difference in the prevalence of symptomatic CHD and claudication was greater in diabetic than in nondiabetic subjects. In both areas and in both sexes the serum lipid pattern was more atherogenic and hypertension was more frequent in diabetic than in nondiabetic subjects. In both diabetic and nondiabetic subjects, serum total-cholesterol level was somewhat higher and hypertension was more frequent in East Finland than in West Finland. The East-West difference in serum total-cholesterol was greater in diabetic than in nondiabetic subjects. In multiple logistic analyses including cardiovascular risk factors, diabetes status, and area of residence, residence in East Finland was found to be, in addition to diabetes, a strong independent factor associated with CHD, particularly in men.

Multiple clinic and home blood pressure measurements versus ambulatory blood pressure monitoring.

To compare multiple clinic and home blood pressure (BP) measurements and ambulatory BP monitoring in the clinical evaluation of hypertension, we studied 239 middle-aged pharmacologically untreated hypertensive men and women who were referred to the study from the primary healthcare provider. Ambulatory BP monitoring was successfully completed for 233 patients. Clinic BP was measured by a trained nurse with a mercury sphygmomanometer and averaged over 4 duplicate measures. Self-recorded home BP was measured with a semiautomatic oscillometric device twice every morning and twice every evening on 7 consecutive days. Ambulatory BP was recorded with an auscultatory device. Two-dimensionally controlled M-mode echocardiography was successfully performed on 232 patients. Twenty-four-hour urinary albumin was determined by nephelometry. Clinic BP was 144.5+/-12.6/94.5+/-7.4 mm Hg, home BP (the mean of 14 self-recorded measures) was 138.9+/-13.1/92.9+/-8.6 mm Hg, home morning BP (the mean of the first 4 duplicate morning measures) was 137.1+/-13.7/92.4+/-9.2 mm Hg, daytime ambulatory BP was 148.3+/-13. 9/91.9+/-7.8 mm Hg, nighttime ambulatory BP was 125.5+/-16.4/75. 6+/-8.9 mm Hg, and 24-hour ambulatory BP was 141.7+/-14.0/87.2+/-7.6 mm Hg. Pearson correlation coefficients of clinic, home, home morning, and daytime ambulatory BPs to albuminuria and to the characteristics of the left ventricle were nearly equal. In multivariate regression analyses, 36% (P<0.0001) of the cross-sectional variation in left ventricular mass index was attributed to gender and home morning systolic BP in models that originally included age, gender, and clinic, self-measured home morning, and ambulatory daytime, nighttime, and 24-hour systolic and diastolic BPs. We concluded that carefully controlled nonphysician-measured clinic and self-measured home BPs, when averaged over 4 duplicate measurements, are as reliable as ambulatory BP monitoring in the clinical evaluation of untreated hypertension.

Alexithymic features in relation to the dexamethasone suppression test in a Finnish population sample.

Hypothesizing that a positive DST result could reflect an aberrant stress reaction in subjects with alexithymic features, the authors investigated the relationship between alexithymic features and DST results in 266 subjects from a Finnish adult population sample. Alexithymic features were assessed with the Beth Israel Questionnaire. The authors found a statistically significant association between observed alexithymic features and a positive DST result. This association could be seen after adjustment separately for age, social rank, marital status, and the occurrence of depression.

Selegiline in the treatment of narcolepsy.

We treated 17 narcolepsy patients in a placebo-controlled, double-blind, crossover trial with 10-, 20-, 30-, and 40-mg daily doses of selegiline, a monoamine oxidase inhibitor widely used in Parkinson's disease. There was a dose-dependent as well as a statistically and clinically significant improvement in narcoleptic symptoms and polygraphic measures. At 40 mg, there was a 36% reduction in the number of daytime sleep episodes and a 34% reduction in their duration (compared with placebo, mean values). The number of excessive sleepiness episodes decreased by 43%, and the duration decreased by 47%. The number of cataplectic attacks was reduced by 89%. On the multiple sleep latency test, the REM sleep latency increased from 5.0 to 13.3 minutes, and the number of sleep-onset REM periods decreased from 3.1 to 0.6. Sleep (S1) latency was not changed. No intolerable adverse events occurred. The effective dose range was 20 to 40 mg, requiring a low-tyramine diet, which was easy to maintain. In conclusion, selegiline alleviates both main symptoms of narcolepsy--the abnormal sleep tendency and cataplexy. Thus, treatment with selegiline makes it possible to avoid polypharmacy and to use a potent stimulant without known addiction risk.

Effects of five years of cardiac rehabilitation after coronary artery bypass grafting on coronary risk factors.

Coronary risk factors were studied in 119 patients randomly assigned to cardiac rehabilitation and compared with 109 patients receiving standard care alone after coronary artery bypass grafting. The long-term impact of rehabilitation on risk factors was modest in patients undergoing elective coronary surgery.

Can treatment outcome of chronic low back pain be predicted? Psychological disease consequences clarifying the issue.

OBJECTIVE: To search for generalizable, psychological predictors of chronic pain treatment outcome. DESIGN: The prognostic power of the psychological predictors, classified into subareas of function, i.e., impairments, disabilities, and handicaps, was compared in predictive situations varying with the quality of patient samples, programs, and outcome measures. SETTING: Four rehabilitation centers in Finland providing "functioning activation" or more passive "spa resort" treatment programs for low back pain patients. PATIENTS: 173 low back pain patients for whom the inpatient rehabilitation program was funded by the Finnish Social Insurance Institution. OUTCOME MEASURES: The measures were panel assessment of global functioning (DSM III Axis V), self-report of handicap (Million), panel assessment of handicap (WHO index), panel assessment of adherence (four rating scales), and self-report of well-being (Faces scale). RESULTS: Multivariate, stepwise regression analyses suggested that the disability and handicap measures of functioning may be more effective predictors than impairment measures, which, however, add to the variance explained by the former. However, the predictive power of psychological impairments, disabilities, and handicaps varied with differences in patient group, outcome measure, and program. CONCLUSION: The "general predictors" of chronic pain treatment outcome may be difficult to find. Therefore, planning treatment for the individual patient may always have to be based on accurate multiaxial and multidimensional assessment of patient functioning.

Self-perceived fatigue and cortisol secretion in a community sample.

The possible relation of cortisol secretion to self-perceived fatigue was examined in an adult community sample. Serum cortisol levels measured after the dexamethasone suppression test (DST) did not predict fatigue whereas depression assessed by the Beck Depression Inventory (BDI) and current medical treatment were significant and independent predictors. Confounding variables such as age, gender, body mass and social status were not predictive of fatigue. Of putative hypothalamic-pituitary-adrenal abnormalities hypersecretion of cortisol does not typify subjects with self-perceived fatigue.

Prospective randomized comparison of endonasal endoscopic dacryocystorhinostomy and external dacryocystorhinostomy.

OBJECTIVES AND STUDY DESIGN: The advent of the rigid endonasal endoscope and the development of functional endoscopic sinus surgery (FESS) technique have awakened interest in an endonasal endoscopic dacryocystorhinostomy (EESC-DCR) in treating nasolacrimal obstruction. This prospective, randomized study compares EESC-DCR with traditional external dacryocystorhinostomy (EXT-DCR) for their success rates, surgical duration, and postoperative symptoms. PATIENTS AND METHODS: Sixty-four cases in 60 patients with primary acquired nasolacrimal sac or duct obstruction were divided into two subgroups by symptoms (simple epiphora/chronic dacryocystitis). These patients were randomized within both subgroups into two operation groups. Altogether 32 EESC-DCRs and 32 EXT-DCRs were performed. The final follow-up visit was at 1 year. The patency of the lacrimal passage was investigated by irrigation and patients were questioned about their symptoms. RESULTS: The success rate at 1 year after surgery was 75% for EESC-DCR and 91% for EXT-DCR after primary surgery. The difference was not statistically significant (P = .18). The success rate after secondary surgery with a follow-up time of 1 year was 97% in both study groups. The average duration for EESC-DCR was 38 minutes, and 78 minutes for EXT-DCR, (P < .001). CONCLUSIONS: EXT-DCR, when compared with EESC-DCR, appears to give a higher, although not statistically significant, primary success rate, but the secondary success rates are equal, indicating that these two different DCR techniques are acceptable alternatives.

Patient classification, a key to evaluate pain treatment: a psychological study in chronic low back pain patients.

It has been proposed that pain treatment evaluation is hindered by heterogeneous properties of patient samples. Therefore, to facilitate pain treatment evaluation in this psychological study, a heterogeneous group of chronic low back pain patients was classified into more homogeneous subgroups. Two designs were used to compare the outcome by the "functioning activation" and the "spa resort" type of rehabilitation. In the first design, the outcome was compared in groups, clinically homogenized by sociodemographic variables and in respect to contraindications for heavy physical training. In the second design, the pain patient subgroups, homogenized by cluster analysis technique in accordance with the psychological profiles of functioning, were compared in their response to treatments. The results indicated that the outcome evaluation was facilitated by the latter design releasing more specific information about the effects of the program quality, the patient characteristics, and their interaction on the improvement by rehabilitation. It was concluded that in treatment outcome analysis, the subgroup's homogeneity must be considered.

Intensive physical and psychosocial training program for patients with chronic low back pain. A controlled clinical trial.

STUDY DESIGN: The authors conducted a controlled clinical trial with 1-year follow-up to define the effectiveness of an intensive physical and psychosocial training program on patients with low back pain. SUMMARY OF BACKGROUND DATA: The intervention group included 152 patients (mean age 40.5 yr, Million index 45.1/100), and the reference group included 141 patients (mean age 40.4 yr, Million-index 44.5/100). METHODS: The progressive intervention program consisted of intensive physical training and psychosocial activation. The outcomes were physical and psychosocial measures, the pain and disability index (Million), sick leaves, and occupational handicap. RESULTS: The intervention was more efficient with respect to physical measures and pain and disability index. There were only mild or no differences in changes between the study groups in psychologic variables, sick leaves, or retirement. CONCLUSIONS: The intervention program could improve physical disability, but to improve occupational handicap, activities of the whole society (social legislation, labor market policy) are needed.

Attitudes of patients with breast and prostate cancer toward complementary therapies in Finland.

This study aimed to describe the attitudes of patients with breast cancer and those with prostate cancer toward complementary therapies. The data were collected with a postal questionnaire administered to 216 patients with breast cancer (response rate, 55.4%) and 1 90 patients with prostate cancer (response rate, 54.9%) in southern and southwestern Finland. The questionnaire was composed of 44 Likert-type statements, which were analyzed using descriptive statistics, chi2 tests, t tests, and two-way analyses of variance. More than half (54%) of the patients with breast cancer and 45% of the patients with prostate cancer believed that people with cancer may benefit from complementary therapies, although they did not think these therapies actually could cure cancer. More than half of the respondents were dubious about using complementary therapies as long as there was no solid scientific evidence. Most believed that complementary therapies were used because they gave people hope (women, 88%; men, 72%) or "something to cling to" (women, 83%; men, 76%). The respondents believed most in dietary therapies and least in healing. There was much confusion and uncertainty about the professional competencies and expertise of the people who provided complementary therapies. Approximately one fourth of the respondents had spoken to their physician about complementary therapies. Only a few had talked about the matter with nursing staff. About half of the respondents thought that physicians and nurses took a negative attitude toward complementary therapies. In both groups, patients who had talked with their physician about complementary therapies tended to show a more positive attitude.

An empirical investigation of the 'Biopsychosocial Disease Consequence model': psychological impairment, disability and handicap in chronic pain patients.

The purpose of this study is to emphasize the meaningfulness of a global, functional rather than a narrow medical view in the efficacy evaluation of chronic pain treatment. Therefore, the 'Biopsychosocial Disease Consequence (BPSDC) model' to assess function more globally than before, is presented in this article. The model is based on two theories: (1) the biopsychosocial approach and (2) WHO's classification of impairments, disabilities and handicaps. In addition to the presentation of the conceptual model, the development of the hypothetical criteria and assessment models for psychological impairments, disabilities and handicaps, and the validity testing of the psychological assessment axis are described. Within each of the three classes, i.e. psychological impairments, disabilities and handicaps, the results supported the independence of the hypothetical criteria from each other. On the other hand, results suggested that some changes to the hypothetical assessment models for some of the criteria might be valuable. It was concluded that although the most adequate psychological assessment models for function, found in this study, can be considered as robust and recommendable as one set of tools for functional assessment, the main aim of this article is to encourage multidisciplinary team efforts to develop and systematize the assessment procedures of function in patients suffering from chronic diseases.
