Background: Given the documented importance of employment for middle-aged and older adults’ mental health, studies of the association between their number of work hours and depressive symptoms are needed. Objectives: To examine the association between the number of work hours and depressive symptoms in Korean aged 45 and over. Methods: We used data from the first wave to fourth wave of the Korea Longitudinal Study of Aging. Using the first wave at baseline, data included 9845 individuals. Depressive symptoms were measured using the 10-item Center for Epidemiological Studies Depression scale. We performed a longitudinal analysis to estimate the prevalence of depressive symptoms by work hours. Results: Both unemployed males and females aged 45–65 years were associated with higher depressive symptoms (β = 0.59, p < 0.001; β = 0.32, p < 0.001). Females working ≥ 69 h were associated with higher depressive symptoms compared to those working 41–68 h (β = 0.25, p = 0.013). Among those both middle-aged and older adults, both males and females unemployed were associated with higher depressive symptoms. Those middle-aged female working ≥69 h were associated with higher depressive symptoms. Conclusions: An increase in depressive symptoms was associated with unemployed males and females working ≥69 h compared to those working 41–68 h. Although this association was found among middle-aged individuals, a decrease in depressive symptoms in both sexes was associated with working 1–40 h. Depressive symptoms should decrease by implementing employment policies and social services to encourage employers to support middle-aged and older adults in the workforce considering their sex and age differences.

This paper examines unhealthy eating in a middle aged Scottish population. Data from a 1989 survey of 5 00 Scottish men and women aged 45 to 59 years are used to explore inter-relations among five items of unhealthy eating, smoking and alcohol consumption. The results show that unhealthy eating behaviours are highly correlated, indicating strong links among certain nutrition habits. The findings also reveal that such patterns of unhealthy eating vary considerably between males and females. Finally, unhealthy eating behaviours were also found to be significantly associated with smoking and alcohol consumption. Implications of these findings for future research in epidemiology and health promotion are considered.

Bench press exercise is extensively used for chest and shoulder strength development. Joint stiffness is one of the side-effects that may occur with the exercise. This study aimed to investigate the relationship between bench press load and shoulder joint stiffness. Sixteen female rugby players (body weight 53.98 ± 7.14 kg, height 156 ± 5.38 cm) selected for Perak SUKMA 2018 team were assessed during centralized training ~9 months prior to the competition. Shoulder joint stiffness in terms of external and internal rotation range of motions were assessed by a qualified physiotherapist. The participants then performed one repetition maximum (1-RM) Bench press, according to the National Strength & Conditioning Association (NSCA)'s protocol.  Standardized warm-up and cooling-down protocol were prescribed to the participants accordingly. Pearson correlation coefficient was used for statistical correlation analysis. Both side shoulder internal and external rotation range of motion measurements showed a negative correlation (r=-0.190 internal, r=-0.285 external) with bench press (average 1-RM load 50.83 ± 9.00 kg) performance. Bench press exercises may result in reduced shoulder mobility due to an increase of muscular tightness around the joint. Maintaining normal mobility of shoulder joint throughout any strength training program is warranted and suggested. The finding also highlighted the importance of the mobility program to always be included together with a strength training programme for athletes.
