Socio-demographic Differences in Self-reported Psychological Distress Among 25- to 64-Year-Old Finns

Background Mental health problems are a major public health issue worldwide. The aim of this study was to assess the relative importance of socio-demographic characteristics associated with different domains of psychological distress in Finland. Methods Data source was a nationwide survey “Health Behaviour and Health among the Finnish Adult Population” (AVTK), from years 2002 to 2003 (N = 5425; response rate 66%). Psychological distress was measured by self-reported questions of general mental health (MHI-5), depression, insomnia and stress. Socio-demographic factors included education, employment status, partnership and children living in the household. Main analyses were conducted by multivariate logistic regression. Results Education, employment and partnership were associated with most of the psychological distress outcomes. Respondents with a lower educational level had poor mental health in both genders but less insomnia and stress in men. Those with an intermediate education had the least stress in women. The unemployed and retired were at a higher risk for poor mental health and depression. Moreover, employment status was associated with insomnia and stress in men. Respondents not having a partner showed a higher risk of psychological distress according to all measures. Not having children living in the household was associated with insomnia in women and with less stress in men. Conclusions Socio-demographic factors, such as having a partner and employment status, are associated with several measures of psychological distress indicating the importance of social and economic factors to psychological well-being. The association of education and of having children living at home varies by the domain of psychological distress measure.     

Estimating multivariate autoregressive moving average models by fitting long autoregressions

Some simple methods for the estimation of mixed multivariate autoregressive moving average time series models are introduced. The methods require the fitting of a long autoregression to the data and the computation of consistent initial estimates for the parameters of the model. After these preliminaries the estimators of the paper are obtained by applying weighted least squares to a multivariate auxiliary regression model. Two types of weight matrices are considered. Both of them yield estimators which are strongly consistent and asymptotically normally distributed. The first estimators are also asymptotically efficient while the second ones are not fully efficient but computationally simple. A simulation study is performed to illustrate the behaviour of the estimators in finite samples.     

An efficient method for the estimation of multivariate moving averge models

Durbin's (1959) efficient method for the estimation of univariate moving average models is generalized to the vector case. Strong consistency and asymptotic normality of the estimator is proved. A simulation experiment is performed to illustrate the behaviour of the method in finite samples.     

Effects of exercise on health-related quality of life and fear of falling in home-dwelling older women

This randomized, controlled trial evaluated the effects of exercise on health-related quality of life (HRQoL) and fear of falling (FoF) among 149 home-dwelling older women. The 12-mo exercise program was intended to reduce the risk of falls and fractures. HRQoL was assessed by the RAND-36 Survey, and FoF, with a visual analog scale, at baseline, 12 mo, and 24 mo. On all RAND-36 scales, the scores indicated better health and well-being. The exercise had hardly any effect on HRQoL; only the general health score improved slightly compared with controls at 12 mo (p = .019), but this gain was lost at 24 mo. FoF decreased in both groups during the intervention with no between-groups difference at 12 or 24 mo. In conclusion, despite beneficial physiological changes, the exercise intervention showed rather limited effects on HRQoL and FoF among relatively high-functioning older women. This modest result may be partly because of insufficient responsiveness of the assessment instruments used.     

Perceived physical work capacity,stress, sleep disturbance and occupational accidents among firefighters working during a strike

Fire-fighting and rescue work are arranged in such a way that various kinds of accidents and catastrophes can be handled. In an understaffed situation, such as a strike, this goal may not be met. The objective of this study was to investigate factors associated with perceived physical work capacity, stress, sleep disturbance, and occupational accidents among firefighters who remained at work during an extended strike. A cross-sectional questionnaire study was carried out among 543 firefighters (83% of the target group) in 71 fire brigades in Finland. After the strike had lasted for 9 to 11 weeks, most of the firefighters perceived their physical work capacity to be rather good or very good. Stress increased along with a decreasing number of personnel in a crew (OR= 2.3, CI= 1.0-5.3, for less than 75% of a normal crew vs. normal crew) and with decreasing number of personnel in a shift (OR= 2.4, CI= 1.1-5.4, for less than 25% of normal shift vs. normal shift). Sleep disturbance was reported to occur as soon as the total working time exceeded 50 h/week. Working more than 70 h/week increased the risk of occupational accidents almost 4-fold compared with working no more than 50 h/week. These results suggest that exceptional situations, such as a strike, are a challenge to human capacity. With time, increased stress and sleep disturbance may lead to serious consequences.     

Reflections on the Use of DWR in Intercultural Collaboration

This article is a reflection on a Developmental Work Research project focused on the introduction of information and communication technology in schools in Africa. The longstanding project incited us to examine developmental research partnership as a joint mediated activity that takes place in a developing country. The data include several workshops, Change Laboratories (CLs) in three schools, and ethnography from these schools. By tracing the bottom-up approach of CLs, and to capture the complexity of the effects of related activities represented in the partnership, we were led to focus on dialogue where the dialectic of local and global forces evolve.     

Working For God? Evidence From A Change In Financing Of Nonprofit Health Care Providers In Uganda3

What motivates religious nonprofit health care providers? This paper uses a change in financing of nonprofit health care providers in Uganda to test two theories of organizational behavior. We show that financial aid leads to more laboratory testing, lower user charges, and increased utilization. These findings are consistent with the view that religious nonprofit providers are intrinsically motivated to serve (poor) people and that these preferences matter quantitatively.
