This study was done to identify the effects of weight-bearing exercise(WBE) on bone metabolism.
WBE was performed for 12 weeks by healthy college women. Bone-related parameters were measured four times during this period by evaluating the immunoradiometric assay and enzyme immunoassay. Bone mineral densities(BMDs) were measured by dual energy x-ray absorptiometry before and after the WBE program. Data was analyzed using t-test, paired t-test, x2-test, and repeated measures ANOVA.
Osteocalcin, a bone formation marker, increased more in the experimental group than in the control group based on the interaction between time and group(F=3.29 p=.024). Little difference between the two groups was found for the other parameters: urinary deoxypyridinoline, insulin-like growth factorI, parathormone, serum calcium, and serum phosphorus without showing any time interaction between the groups. The femoral trochanter BMD rose in the experimental group while that of the control group fell, showing a significant difference for BMD(t=3.06 p=.005). However, there was no significant difference between the two groups for changes in BMD of the forearm, lumbar spine, femoral neck, and femoral ward's triangle.
These findings supported the WBE is beneficial for increasing bone formation in college women and long-term application is needed to substantiate the effects of WBE as a intervention in promotion of bone-health.
This study was to identify important predictors of depression among characteristics of caregiving situation and utilized resources in order to provide basic information for effective nursing interventions to reduce depression experienced by family caregivers of older adults with dementia.
Seventy one family caregivers were identified from community service centers and face-to-face interviewed using structured questionnaires. Data were analyzed with descriptive statistics, Pearson correlation and hierarchical multiple regression using SPSS WIN 10.0 program.
Family caregivers reported high levels of depression, moderate levels of social support, and moderate utilization of coping strategies. Female caregivers who (β=.22) utilized ‘negative’ coping strategies more often (β=.48) and ‘cognitive reconstructuring’ coping strategies less often (β=-.23) were more likely to report higher depression (R2=0.63).
Nursing interventions increasing family caregivers' utilization of positive coping strategies such as problem solving, existential growth, and help seeking and decreasing their utilization of negative coping strategies such as self-blaming are needed to decrease their depression levels.
This was to describe the emotions that patients face when diagnosed with cancer to know the problems and coping styles that cancer patients experience during the treatment.
The qualitative method was used for this study. The participants were 90 cancer patients at five general hospital in Pusan, Korea. Data were collected by interviews with a semi-structured questionnaire from November 2000 to June 2001, and were analyzed using the modified constant comparative method.
The most common emotions on the diagnosis of cancer were shock(36.7%), followed by despair(25.6%), acceptance(24.4%), denial(18.9%), complaint(16.7%), and fear(8.9%). The problems identified were the unpleasantness and physical discomfort related with the treatment(50.0%), the feelings of burden(41.1%), finance/occupation(38.8%), and fear of the future(26.6%). Coping styles to problems that the subjects have faced on the course of the treatment were compliance(36.6%), health care(31.1%), positive thinking(22.2%), despair/avoidance(15.5%), seeking social support(6.6%), information seeking(3.3%) and self-control(2.2%).
It is very important to develop nursing interventions which can mitigate shock that patients experience, can help cancer patients to have hope for the future and to positively cope with cancer.
To investigate body compositons and bone mineral density(BMD) in college women and to find the relationship between them.
From January to March of 2001, BMD at four parts(forearm, lumbar, femur and whole body), body mass index(BMI), body fat mass(BFM), lean body mass(LBM) and body fat percentage(%Fat) were measured with the Dual Energy X-ray Absorptiometry. Other physical characteristics were measured with a scale, a height measurer, and questionnaires.
Grouping by the BMI, 43.2% showed low weight, and 5% over weight. When applying the percent Fat, 43.8 % was diagnosed as obesity group. The fact indicate that a majority of college women have unbalanced body composition with high percent Fat, compared to their body weight. Assessing the BMD with the WHO standards, 91.4~95.7% of the BMD of forearm and whole body was normal. But, 40.3% and 33.1~43.9% showed osteopenia at lumbar and femur, and 1.4 %, 0.7~7.2% showed osteoporosis. The BMD at all parts showed significant correlation each other(r=.29~.89, p=.001~.000). Body weight and BMI showed correlations to with BMDs at all parts of the body(r=.19~.46, p=.025~.000; r=.18~.45, p=.039~.000). But the percent Fat had a correlation with only femur neck BMD(r=.19, p=.024).
This study showed a majority of healthy college women were exposed to the risk for osteoporosis. Additional study is required to develop nursing interventions to remove the risk factors of osteoporosis. In particular, the acquisition of balanced body composition is necessary, increasing body weight and BMI through the increase of LBM, not through the quantitative increase of BFM.
