Relationship between an amount of Key Tasks and Job Satisfaction among Caregivers and Nurses in Elderly Care Facilities

OBJECTIVES: The purpose of this study is to examine relationship between an amount of key tasks and job satisfaction among caregivers and nurses in elderly care facilities. METHODS: Questionnaires were mailed to the caring staff of elderly care facilities. After data collection (return rate 70%), information about work situations and health conditions were analyzed among 325 female workers, who were classified to 4 groups as follows; (1) caregivers under 40 years of age (2) caregivers of 40 years or over (3) nurses under 40 years of age (4) nurses of 40 years or over. RESULTS: Mean ages and length of career in caring sector were 37.2 +/- 12.2 yr and 4.5 +/- 3.0 yr for caregivers and 41.6 +/- 9.2 yr and 16.8 +/- 8.9 yr for nurses, respectively. A larger amount of care services were done on average by workers being dissatisfied with their job than by the satisfied workers in each of the 4 groups. The dissatisfied caregivers under 40 years showed significantly higher frequencies (as ratios of 1.4 - 2 to 1) in several care services such as "helping with showers or baths", "helping with eating", "changing diapers", "moving caretakers from bed or chair to wheelchair or vice versa", as compared with the satisfied caregivers under 40 years. Similarly, the 40 plus dissatisfied caregivers helped caretakers sit up in bed significantly more frequently. For nurses, on the other hand, "changing diapers" was found as the only service with a significant difference in frequency between the dissatisfied and the satisfied, but that was limited in the 40 plus age group. A frequency of "changing diapers" was associated with an increase in the risk of job dissatisfaction. CONCLUSIONS: These results suggested that an appropriate amount of each key task in elderly care facilities should be set to prevent staff\'s dissatisfaction with their job from growing excessively.

CHARACTERISTICS OF BONE DENSITY IN ADOLESCENT SYNCHRONIZED SWIMMERS / 体力科学

Forearm bone mineral content for adult white elite synchronized swimmers is lower than that of normative data (Roby et al. 1988). However, bone mineral density (BMD) in local body regions and the body as a whole are unclear in adolescent synchronized swimmers. The purpose of this study was to examine BMD of adolescent synchronized swimmers. This study also examined the relationship between BMD for young athletes and biological (e. g. morphological and functional aspects) and habitual (e. g. physical activity and nutritional state in daily living) variables. Subjects were nine females selected nationwide out of a large number of synchronized swimmers of fourth to sixth grade in elementary school, who participated in an audition with the committee of synchronized swimming in the Japan Swimming Federation. Chronological and bone age were 13.4±1.0 years and 12.7±0.9 years (n=8), respectively. BMD was evaluated in local regions and the body as a whole by dual X-ray absorbtiometry (DXA). Walking was measured by pedometer, and physical activity and nutritional status were analyzed by activity diary and food weighing method, respectively. As a result, mean BMD in athletes tended to be lower than in normal Japanese girls for lower limbs and lumbar vertebra (L2-L4), while it was almost the same between the two groups for whole body, upper limbs, thoracic vertebrae and pelvis. The correlations between BMD for whole body and bone age, the number of years since menarche, body mass, lean body mass and physical activity in leisure time of daily life were significant. An analysis using a general linear model indicated that bone age and active leisure activity together explained 94.6% of the variance of the BMD. These findings indicate that BMD of adolescent synchronized swimmers tended to be unique in local regions. Furthermore, BMD in athletes was affected by the biological maturation level and physical activity in leisure time of daily life.
