Occupational physical activity trends from 1987 to 2017: A nationally representative sample of 160,509 Spanish adults.

The aim of the study was to estimate temporal and updated trends of occupational physical activity (OPA) among Spanish adult population during the period between 1987 and 2017. We used all available rounds of the Spanish National Health Survey (160,509 adults, mean age 44.6 years [SD 16.6], 50.3% women) and multivariate regressions to determine temporal trends of high OPA from 1987 to 2017 in the general working population of Spain. The highest OPA prevalence was observed for participants aged 31-49 years in the 2003 survey. The prevalence of high OPA was generally low, but increased slightly over time in the 18-30, 50-64, and 65-75 years old (p < 0.001 for trend). In contrast, a general reduction in OPA was observed in the 16-17 years old (p < 0.001 for trend). Men consistently showed higher OPA prevalence than women. This study reports an increase in OPA prevalence in Spain from 1987 to 2017, which is low and significant in most socio-demographic groups, but small in absolute terms. The youngest group had a marked decreased in OPA prevalence over the course of the study. Men consistently showed higher OPA prevalence than women, but differences have become smaller in recent years. Our results may assist in the establishment of interventional strategies and future policies among specific subgroups.HighlightsThere is an increase in OPA prevalence in Spain from 1987 to 2017.The youngest group had a marked decreased in OPA prevalence over the course of the study.Men consistently showed higher OPA prevalence than women, but differences have become smaller in recent years.Frequent national surveillance of OPA to monitor long-term development of the working environment should be mandatory.

Handgrip strength and work limitations: A prospective cohort study of 70,820 adults aged 50 and older.

The purpose of the study was to investigate the association between handgrip strength and the incidence of work limitations in European adults aged 50 and older. We conducted a prospective cohort study among adults aged 50 and older from 27 European countries and Israel. Data were collected from the Survey of Health, Ageing and Retirement in Europe (SHARE) waves 1, 2, 4, 5, 6, and 7. Handgrip strength was measured using a hand dynamometer (Smedley, S Dynamometer, TTM) and participants replied to questions about work limitations. Cox regression was conducted for statistical analyses. A total of 70,820 older adults (mean age 61 ± 7.7 years; 54.3 % women) were followed during a mean of 3.8 ± 2.9 years. The fully adjusted model showed that participants with low handgrip strength (<16 kg in women and <27 kg in men) had a significantly higher risk of work limitations compared with participants with normal values of handgrip strength (hazard ratio: 1.36; 95 % confidence interval: 1.28-1.44). Kaplan-Meier trajectories revealed that the survival probability to experience work limitations in the normal handgrip category was 20 % lower than in the low handgrip category in most of the follow-up period. We identified low level of handgrip strength as a risk factor for work limitations in adults aged 50 years or older. This could be used as an accessible measure to screen workers at risk of developing work limitations.

Can a Healthy Lifestyle Prevent Disability Pension among Female Healthcare Workers with Good and Poor Self-Rated Health? Prospective Cohort Study with 11-Year Register Follow-Up.

BACKGROUND: Our purpose was to investigate whether healthy lifestyle habits prevent disability pension among female healthcare workers. METHODS: We conducted a prospective cohort study with an 11-year register follow-up in which 8159 female healthcare workers from Denmark completed a questionnaire concerning self-rated health, work environment, leisure-time physical activity (LTPA), smoking, and body mass index (BMI). Data on disability benefit payments were obtained from the Danish Register for Evaluation of Marginalization during an 11-year follow-up. Potential confounders included age, occupational education, psychosocial work factors, and physical exertion during work. RESULTS: Among workers in good health at baseline, smoking, obesity, and low levels of LTPA were risk factors for disability pension during 11-year follow-up. Among workers with poor health, only low levels of physical activity were a risk factor for disability pension. CONCLUSIONS: This underscores the importance of a healthy lifestyle, specially being physically active, for preventing premature exit from the labor market in female healthcare workers.

Importance of frequency and intensity of strength training for work ability among physical therapists.

The aim of the study was to evaluate the association between frequency and intensity of strength training participation and work ability among physical therapists (PTs). The Work Ability Index questionnaire (WAI) and a questionnaire about participation in strength training during leisure time were administered to a sample of Spanish PTs. In addition, participants provided information on gender, age, body mass index, education, substance use, working experience and working hours per week. The odds for having excellent WAI (score 44-49) as a function of intensity or frequency of strength training participation were determined using binary logistic regression controlled for various confounders. Data from 981 PTs were analysed. High-intensity strength training (> 80% 1 RM) showed strong associations with excellent WAI (odds ratio = 9.7; 95% confidence interval, 2.9-31.6). In addition, performing strength training more than 3 times per week was associated with excellent WAI (odds ratio = 1.79; 95% confidence interval, 1.24-2.59), however, no significant associations were found with lower levels of frequency and intensities. High-intensity strength training 3 times per week is associated with excellent WAI among PTs. Training programs meeting these features may importantly contribute to maintain or improve WAI.
