Nutritional profiles in middle-aged trained and untrained women were compared both before and after menopause. Subjects were assigned to one of four groups : (1) pre-menopausal trained (Pre-T: n=14, aged 43±5 years, running distance 56±27 km/week, Vo₂max 49±4ml/ kg/min, mean±SD), (2) pre-menopausal untrained (Pre-UT: n=25, 42±5 years, 34±5 ml/kg/ min), (3) post-menopausal trained (Post-T: n=19, 53±3 years, 49±17 km/week, 42±6 ml/ kg/min), (4) post-menopausal untrained (Post-UT: n=26, 54±3 years, 31±3 ml/kg/min) . There were no significant differences in hematocrit (range 38.7 to 39.3%), hemoglobin (12.8 to 13.1 g/dl) and total protein (6.9 to 7.1 g/dl) among the four groups. Serum iron concentrations in the post-menopausal women (Post-T: 97±30μg/dl, Post-UT: 106±29μg/dl) were relatively higher than in the pre-menopausals (Pre-T: 85±35 pg/dl, Pre-UT: 78±33 pg/dl) . Mean total iron binding capacity in Post-UT (326 pg/dl) was lower than other groups (352 to 361 pg/dl) . Higher serum ferritin levels were observed in the post-menopausal women (Post-T : 35.8±27.5 ng/ml, Post-UT : 60.4±47.1 ng/ml) than the pre-menopausals (Pre-T: 18.3±13.1 ng/ml, Pre-UT: 16.6±10.7ng/ml) . Intake levels of the four groups with regard to the major nutrients were sufficient as compared with the recommended dietary allowance appropriate for age, sex and physical activity level. Intakes of calcium, iron and vitamins B₁, B₂ and niacin were higher in the trained groups than in the untrained. Regularly performed endurance exercise resulted in higher protein and iron intakes associated with higher energy intakes both before and after menopause. These results suggest that nutritional status of middle-aged women who regularly perform vigorous endurance running could be adequate for maintaining their health in a good state.

Purpose: This study aimed to investigate the relationship between the expectations of unit-level nurses from nursing assistants (NAs), frequency of individual NAs' information-sharing behaviors with nurses, and the effect of NAs’ self-perceived roles on this relationship. NAs provide patient care along with nurses, and their information-sharing behaviors with nurses may be influenced by the expectations of the nurses. Methods: Nurses and NAs from 104 integrated community care (sub- and postacute) units were included in this Japanese cross-sectional study conducted from July to September 2018. Nurses' expectations from NAs and the NAs' self-perceived roles and information-sharing frequency were measured. Multilevel mediation analysis was performed for NAs’ information-sharing behaviors, such as expressing, asking, providing linguistic responses, and providing feedback. Results: Unit-level nurses' expectations from NAs were associated with the frequency of NAs' asking and responding behaviors with nurses (p < .05), mediated by the NAs' self-perceived roles. The frequency of NAs’ expressing behaviors and feedback were also associated with their self-perceived roles (p < .001). Conclusions High expectations of unit-level nurses from NAs led to better perception by NAs of their roles and led to better information-sharing behaviors. Educating nurses on NAs’ roles may improve information-sharing between nurses and NAs that leads to safe and appropriate care to patients.
