RESUMO
BACKGROUND: Unemployment is associated with reduced physical and psychological well-being. Perceived health is an important factor influencing health outcomes as well as successful returns to work. This study aims to determine the extent to which perceived health correlates with mental health, various health risk characteristics and socio-demographic characteristics in a setting-selected sample of long-term unemployed persons. METHODS: Using SF-12, 365 long-term unemployed persons were assessed for self-perceived health and various socio-demographic and health characteristics. Perceived health data of the sample was compared to the German SF-12 reference population. Bivariate analyses and multiple linear regression models were applied to identify those variables significantly associated with perceived health. RESULTS: The study population reported poorer perceived health compared with the general population. Analyses showed that perceived mental health was significantly worse in women, among persons with heightened depression and anxiety scores, and in participants reporting reduced levels of physical activity. Perceived physical health was significantly lower among older persons, participants with a higher BMI, and participants with heightened depression and anxiety scores. Both mental and physical health were worse among the unemployed assigned to an employment center as compared to those engaged in the secondary labor market. In total, 36% of the variance in the SF-12 mental score and 20% of the variance in the SF-12 physical score were explained by the factors included in the final multiple linear regression models. CONCLUSIONS: Perceived health among a select group of long-term unemployed is reduced to a clinically relevant extent compared to the general population. The preliminary findings underline an association between mental health and perceived health. Negative self-perceptions of health were also associated with the labor market setting and some of the socio-demographic and health behavior variables. Further research is needed to determine risk factors leading to reduced perceived health in the unemployed. The strong association between mental health and perceived health suggests interventions targeting mental health are urgently needed to positively influence perceived health, a key determinant of individuals' chances to successfully return to work.

OBJECTIVE: To examine the long-term effects of a stress management intervention (SMI) based on the effort-reward imbalance (ERI) model, on psychological and biological reactions to work stress. METHODS: 174 lower or middle management employees (99% male) were randomly assigned to an intervention or a waiting control group. The programme comprised 24 × 45 min group sessions (2 full days followed by two 4 × 45 min sessions within the next 8 months) on individual work stress situations. The primary endpoint was perceived stress reactivity (Stress Reactivity Scale, SRS), while secondary endpoints were salivary cortisol and α-amylase, anxiety and depression, and ERI. Assessments were repeated in 154 participants 1 year later. RESULTS: SRS score decreased in both groups. A two-factor ANOVA with repeated measures showed a significant time × group effect (F=5.932; p=0.016) with the greater reduction in the intervention group. For SRS, the effect size (Cohen's d) after 1 year was d=0.416 in the intervention and d=0.166 in the control group. α-Amylase as a measure of sympathetic nervous system activation, decreased more strongly in the intervention group (area under the daytime curve and daytime slope: time × group effect p=0.076 and p=0.075). No difference was observed for cortisol. For depression, anxiety and ERI, improvements were higher in the intervention group but did not reach statistical significance. CONCLUSIONS: SMI based on work stress theory, is effective in reducing perceived stress reactivity and sympathetic activation in lower and middle management employees. Other mental health parameters and ERI show a tendency towards improvement. These beneficial effects are present 1 year later.

BACKGROUND: Work related stress is associated with a range of debilitating health outcomes. However, no unanimously accepted assessment tool exists for the early identification of individuals suffering from chronic job stress. The psychological concept of self-perceived stress reactivity refers to the individual disposition of a person to answer stressors with immediate as well as long lasting stress reactions, and it could be a valid indicator of current as well as prospective adverse health outcomes. The aim of this study was to determine the extent to which perceived stress reactivity correlates with various parameters of psychosocial health, cardiovascular risk factors, and parameters of chronic stress and job stress in a sample of middle-aged industrial employees in a so-called "sandwich-position". METHODS: In this cross-sectional study, a total of 174 industrial employees were assessed for psychosocial and biological stress parameters. Differences between groups with high and low stress reactivity were analysed. Logistic regression models were applied to identify which parameters allow to predict perceived high versus low stress reactivity. RESULTS: In our sample various parameters of psychosocial stress like chronic stress and effort-reward imbalance were significantly increased in comparison to the normal population. Compared to employees with perceived low stress reactivity, those with perceived high stress reactivity showed poorer results in health-related complaints, depression, anxiety, sports behaviour, chronic stress, and effort-reward imbalance. The educational status of employees with perceived low stress reactivity is higher. Education, cardiovascular complaints, chronic stress, and effort-reward imbalance were moderate predictors for perceived stress reactivity. However, no relationship was found between stress reactivity and cardiovascular risk factors in our sample. CONCLUSIONS: Job stress is a major burden in a relevant subgroup of industrial employees in a middle management position. Self-perceived stress reactivity seems to be an appropriate concept to identify employees who experience psychosocial stress and associated psychological problems at the workplace.

OBJECTIVES: To identify relevant changes in process variables that are associated with outcome following an exercise and a multidisciplinary secondary prevention program for low back pain. METHODS: Data from a randomized controlled clinical trial to examine the effectiveness of an exercise and a multidisciplinary prevention program were analyzed using multiple regression analyses. The specific goal was to examine the amount of variance in changes in "interference" postintervention that could be explained by prechanges to postchanges in physical and psychologic parameters, and to determine if there are interactions between physical/psychologic parameters and the program type. RESULTS: One hundred sixty-two (89%) participants were included in the regression analyses. Reductions of interference at postmeasurement were explained best by reductions of pain intensity and catastrophizing in the multidisciplinary and the exercise prevention program. No significant interaction between the changes in process variables and the program type was found. The final model could explain 68.7% of variance. CONCLUSIONS: Owing to methodologic limitations, strong conclusions cannot be drawn from this study. The findings suggest that treatment success in exercise and multidisciplinary interventions might be influenced by the same change factors, namely changes in pain and psychologic factors. The results raise the question of whether the mechanism through which exercise works, is improve in physical variables, or rather a change in psychologic attributes, in that people correct their irrational cognitions by making experiences that differ from their expectations. If these findings can be confirmed in longitudinal studies with more measurement points, they would have implications for treatment refinement.

This study aimed to investigate long-term stability and variability of diurnal cortisol and alpha-amylase patterns. Diurnal cortisol and alpha-amylase secretion patterns were assessed on a single workday with three waves of measurement across a total time period of 24months in 189 participants. Separate hierarchical linear models were analyzed, with and without a number of potential predictor variables (age, BMI, smoking, chronic stress, stress reactivity). While low long-term stability was found in diurnal cortisol, the stability of diurnal alpha-amylase was moderate across the time period of 24months. Several predictor variables had a positive impact on diurnal cortisol and alpha-amylase secretion patterns averaged across waves. Our findings underpin the notion that long-term stability is not necessarily warranted in longitudinal studies. It is important to choose an appropriate study design when attempting to disentangle clinically and biologically relevant changes from naturally occurring variations in diurnal cortisol and alpha-amylase.

BACKGROUND: Long-term unemployment is associated with poorer mental health. The aim of this study was to evaluate the effectiveness of a health promotion program using the train-the-trainer approach on health-related quality of life (HRQoL) and mental health of long-term unemployed persons. METHODS: A prospective parallel-group study was conducted among 365 long-term unemployed persons. 287 participants (179 members of the intervention group IG and 108 members of the control group) were reassessed after three months. The intervention comprised both individual sessions based on Motivational Interviewing and participatory group sessions; no health promotion program was administered in the control group. The endpoints were HRQoL (SF-12), depression, and anxiety. The effect size of the change across time in the IG and CG was measured by Cohen's d. To assess the significance of group differences in the change across time, a random effects model was used. RESULTS: Within three months HRQoL improved and anxiety and depression decreased significantly in the IG. A significant intervention effect was observed for anxiety (p = 0.012). Effect sizes in the IG were small to moderate in terms of Cohen's d (anxiety: d = -0.33; SF-12 mental: d = 0.31; depression: d = -0.25; SF-12 physical: d = 0.19). CONCLUSIONS: The health promotion program, based on a train-the-trainer approach, showed positive effects on HRQoL and mental health, especially anxiety, of long-term unemployed persons, a highly burdened target group where an improvement in mental health is a crucial prerequisite to social participation and successful reintegration into the job market.

OBJECTIVE: The objective of this study was to examine whether a multimodal, secondary prevention program (MP) is superior to a general physical exercise program (EP) in influencing the process leading to chronic low back pain (LBP) in nurses with a history of back pain. DESIGN: The study was conducted as a randomized controlled parallel-group trial. SETTING: The interventions were performed in a single center at the Department of Physical and Rehabilitation Medicine at the University of Munich in Germany. PARTICIPANTS: A total of 235 nurses from 14 nearby hospitals and nursing homes who experienced at least one episode of back pain during the previous 2 years were invited into the study. Of these, 183 nurses were enrolled and 169 (83 in the MP and 86 in the EP) qualified for the intent-to-treat analysis. INTERVENTIONS: The EP consisted of 11 group sessions, each lasting 1 hour. After introductory sessions, subsequent sessions included general physical strengthening and stretching exercises as well as instructions for a home-training program. The MP consisted of 17 group sessions of 1.75 hours and one individual session of 45 minutes. In addition to the full EP, the MP included 5 psychological units, 7 segmental stabilization exercises units, and 8 ergonomic and workplace-specific units. MAIN OUTCOME MEASUREMENTS: The primary study end-point variable was pain interference, and the secondary study end-point variables were pain intensity and functioning as measured with the West Haven-Yale Multidimensional Pain Inventory and the Short Form-36, respectively. These study end-point variables were defined a priori. RESULTS: There was no statistically significant difference between the 2 groups. Small-to-moderate effects were observed in both intervention programs across all study end-point variables. For pain interference, the effect size at 12 months after intervention was 0.58 in the MP and 0.47 in the EP. CONCLUSIONS: A multimodal program is not superior to a general exercise program in influencing the process leading to chronic LBP in a population of nurses with a history of pain. The most likely explanation is a common psychological mechanism leading to improved pain interference that is irrespective of the program used. Considering the lower resources of the general exercise program, the expense for a multimodal program is not justified for the secondary prevention of LBP and disability.

INTRODUCTION: A clearer understanding of the factors involved in improving lifting-capacity may assist professional health workers to enhance patient's functioning and minimize chronic back pain. However, few studies have examined this association. This study is part of a trial comparing two secondary back pain prevention programs. It aims to identify anthropometric, physical, psychic and demographic baseline variables (baseline model), and over time change variables (comprehensive model), which explain the alteration of lumbar isoinertial lifting-capacity, from baseline to post-treatment. METHODS: The association between these variables' baseline- or change values, and the change of lifting-capacity (PILE-test) over time, were analyzed with multiple regression analyses. Potential variables for the regression analyses were identified within a standardized stepwise selection process. RESULTS: In the baseline model, 35.2% of the variance in lifting-capacity was mainly explained by a low baseline score of lumbar lifting-capacity, high body weight and gender. In the comprehensive model, 41.9% could be mainly explained by the same baseline variables, an increase of perceived exertion during the PILE-tests and decrease of fear-avoidance caused by work. CONCLUSIONS: The results suggest that treatments to improve lifting-capacity in individuals with mild low back pain should particularly address the reduction of fear-avoidance beliefs. Although strong conclusions cannot be drawn from this study due to methodological limitations, they may be helpful to assign patients to appropriate and most beneficial treatment programs, as well as to develop specific programs. Fear-reduction may be an important target for early interventions in regard to functional capacity.

Systematic reviews have shown that as non-operative treatments exercise, behavioural and multimodal treatment programs are effective for chronic low back pain. There is, however, a lack of knowledge concerning the association between changes in treatment process variables and changes in outcome for the three treatment forms. The objective of this systematic review was to evaluate which changes in treatment process variables predict outcome of exercise, behavioural and multimodal treatment of chronic low back pain. Medline, Embase and PsychInfo were systematically searched. A descriptive analysis was used to summarize the results regarding the outcomes pain, disability and return to work (RTW). 13 studies were identified. The results showed that functional coping mechanisms and pain reduction were associated with a decrease in disability and increase in RTW, and physical performance factors were not. Related to pain reduction decreases in disability, functional coping mechanisms as well as physical performance factors were associated. Strong conclusions cannot be drawn from this review, because of the heterogeneity and the limited number of studies. The results of this review raise the question if changes in behavioural variables and reductions of disability which facilitate an improvement in function, may be more important than physical performance factors for successful treatment of chronic low back pain. This is relevant for the refinement of future treatment programs.

STUDY DESIGN: A systematic review of randomized controlled trials. OBJECTIVES: To evaluate the effectiveness of segmental stabilizing exercises for acute, subacute and chronic low back pain with regard to pain, recurrence of pain, disability and return to work. METHODS: MEDLINE, EMBASE, CINAHL, Cochrane Controlled Trials Register, PEDro and article reference lists were searched from 1988 onward. Randomized controlled trials with segmental stabilizing exercises for adult low back pain patients were included. Four comparisons were foreseen: (1) effectiveness of segmental stabilizing exercises versus treatment by general practitioner (GP); (2) effectiveness of segmental stabilizing exercises versus other physiotherapy treatment; (3) effectiveness of segmental stabilizing exercises combined with other physiotherapy treatment versus treatment by GP and (4) effectiveness of segmental stabilizing exercises combined with other physiotherapy treatment versus other physiotherapy treatment. RESULTS: Seven trials were included. For acute low back pain, segmental stabilizing exercises are equally effective in reducing short-term disability and pain and more effective in reducing long-term recurrence of low back pain than treatment by GP. For chronic low back pain, segmental stabilizing exercises are, in the short and long-term, more effective than GP treatment and may be as effective as other physiotherapy treatments in reducing disability and pain. There is limited evidence that segmental stabilizing exercises additional to other physiotherapy treatment are equally effective for pain and more effective concerning disability than other physiotherapy treatments alone. There is no evidence concerning subacute low back pain. CONCLUSION: For low back pain, segmental stabilizing exercises are more effective than treatment by GP but they are not more effective than other physiotherapy interventions.
