Physical working conditions and subsequent sickness absence: a record linkage follow-up study among 19-39-year-old municipal employees.

PURPOSE: Physical work exposures are associated with sickness absence among older employees. We aimed to examine if they similarly contribute to all-cause sickness absence during early and mid-careers. METHODS: We used questionnaire data on physical work exposures linked to register data on sickness absence from 3542 municipal employees aged 19-39 years. Follow-up for the number of sickness absence days was 12 months. Exposures to physical workload, occupational environmental hazards, and sedentary work were divided into quartiles. In addition, duration of daily exposure to heavy work was included. Negative binomial regression models were used. RESULTS: Higher exposure to physical workload or hazardous exposures was associated with a higher number of sickness absence days. The age and gender adjusted rate ratios for sickness absence days among the participants whose exposure to physical workload was in the highest exposure quartile were 2.1 (95% CI 1.8‒2.5) compared with those whose exposure was in the lowest quartile. In addition, rate ratios for sickness absence days among participants who reported that they do heavy physical work 1.1‒2.0 h, 2.1‒4.0 h or over 4 h daily were 1.6 (1.3‒1.9), 1.5 (1.3‒1.8) and 1.7 (1.5‒2.1), respectively, compared with those who reported not doing physical work. Further adjustment for lifestyle factors or health characteristics attenuated the associations only slightly. CONCLUSION: Exposure to physically demanding work is associated with a higher number of sickness absence days among municipal employees below 40 years of age. Physical working conditions should be considered when aiming to support later work ability.

Changes in leisure-time physical activity and physical and mental health functioning: a follow-up study.

Functioning will be an increasingly important issue in Finland over the coming decades as the proportion of the population aged 65 and older is growing significantly. However, the associations between changes in physical activity and subsequent health functioning are poorly understood. The aim of this study was to examine how changes in physical activity relate to concurrent and prospective levels of health functioning. Cohort data from the Helsinki Health Study were used. Phase 1 (n = 8960, response rate 67%, 80% women) was conducted among 40- to 60-year-old employees of the City of Helsinki in 2000-2002, phase 2 in 2007 (n = 7332, response rate 83%), and phase 3 in 2012 (n = 6814, response rate 79%). Linear mixed models were used as the main statistical method. Increasing physical activity was associated with higher concurrent and prospective levels of physical health functioning, whereas decreasing activity was associated with lower levels of physical health functioning. The associations were stronger with physical than with mental health functioning. Promoting physical activity among aging people may help to maintain their level of health functioning.

Association of physical workload and leisure time physical activity with incident mobility limitations: a follow-up study.

OBJECTIVES: To examine individual as well as joint associations of physical workload and leisure time physical activity with incident mobility limitations in initially well-functioning middle-aged workers. METHODS: This study is based on 6-year follow-up data of the Danish Longitudinal Study on Work, Unemployment and Health. Physical workload was reported at baseline and categorised as light, moderate or heavy. Baseline leisure time physical activity level was categorised as sedentary or active following the current recommendations on physical activity. Incidence of mobility limitations in climbing stairs and running among initially well-functioning workers (n=3202 and n=2821, respectively) was assessed during follow-up. RESULTS: Higher workload increased whereas active leisure time decreased the risk of developing mobility limitations. The incidence of limitations increased progressively with higher workload regardless of level of leisure time physical activity, although the risks tended to be higher among those with sedentary leisure time compared with their active counterparts. All in all, the risk for onset of mobility limitations was highest among those with heavy workload combined with sedentary leisure time and lowest among those with light workload combined with active leisure time. CONCLUSIONS: Although leisure time physical activity prevents development of mobility decline, high workload seems to accelerate the progression of mobility limitations among both those with active and sedentary leisure time. Therefore, efforts should be made to recommend people to engage in physical activity regardless of their physical workload.

Musculoskeletal pain and physical functioning in the oldest old.

BACKGROUND: Little is known about the impact of pain on physical functioning among the oldest-old subjects. In this study, we first examined the associations between the number of painful sites and measures of physical functioning reflecting different stages of the disablement process (physical impairment, functional limitation and disability) among nonagenarians (more than ninety years old persons). Second, we described the effect of painful sites on disability during a 2-year follow-up period. METHODS: This study is based on baseline (n = 1177) and 2-year follow-up (n = 709) data of the nationwide Danish 1905 cohort study. Musculoskeletal pain was assessed as reported pain in back, hips or knees when moving or resting. Physical performance measures included maximum grip strength and habitual walking speed. Disability in performing activities of daily living was defined as the need for assistive device or personal help in transferring, dressing, washing, using toilet and/or walking indoors. RESULTS: At baseline, the number of painful sites was significantly associated with measured grip strength and walking speed as well as self-reported disability in a stepwise manner; the more sites with pain, the poorer the physical functioning. The follow-up analyses showed corresponding but slightly weaker stepwise associations between baseline pain and disability level at follow-up, and indicated that although on the whole, single or multi-site pain did not predict the onset of disability, multi-site pain increased the risk of developing severe disability. CONCLUSIONS: The findings of this study suggest that musculoskeletal pain in nonagenarians is highly prevalent and is associated with poor physical performance and disability.

Self-reported preclinical mobility limitation and fall history as predictors of future falls in older women: prospective cohort study.

UNLABELLED: We studied if self-reported preclinical mobility limitation, described as modification of task performance without perception of difficulty, predicts future falls in older women with and without fall history. Our results suggest that combined measure of self-reported preclinical mobility limitation and fall history may offer one possibility for inexpensive fall-risk evaluation in clinical practice. INTRODUCTION: We studied if self-reported preclinical mobility limitation predicts future falls in older women with and without fall history. METHODS: The study population consisted of 428 community-living 63-76-year-old women. At baseline, those who expressed no difficulty walking 2 km but reported that it took longer than before or that they did it less often were categorized as having preclinical mobility limitation. Those reporting difficulty in 2-km walk were categorized as having manifest mobility limitation. Fall history was recalled for previous 12 months and dichotomized. The incidence of future falls over 12 months was followed up with fall calendars. RESULTS: During the fall follow-up, a total of 440 falls were reported by 201 participants. Among those with fall history, women with preclinical mobility limitation had almost 4-fold (incidence rate ratios 3.77; 95% CI 1.02-13.92) and those with manifest mobility limitation almost 15-fold (14.66; 2.72-79.00) adjusted risk for future falls compared to those with no mobility limitation and no previous falls. Among women without fall history, preclinical and manifest mobility limitation did not predict future falls nor did fall history without mobility limitation. CONCLUSIONS: Already, early signs of mobility decline with history of falls increase the risk of further falls and should be considered as indications for fall prevention interventions.
