Correlates of Physical Activity in Urban Midwestern African-American Women

BACKGROUND African-American women are at higher risk than white women of cardiovascular disease and stroke. In addition, fewer African-American women reap the cardiovascular benefits of exercise, because of low physical activity. The study goals were to identify personal, social environmental, and physical environmental correlates of physical activity of urban-dwelling, Midwestern, African-American women and to obtain their recommendations for increasing exercise in their communities. METHODS A face-to-face interview (Women and Physical Activity Survey) covering personal, social environmental, and physical environmental correlates of physical activity was administered to 399 volunteer African-American women aged 20 to 50 years, living in Chicago. Physical activity was measured with questions on lifestyle and planned leisure-time activity (exercise) from the Behavioral Risk Factor Surveillance System. RESULTS The women were from a wide socioeconomic spectrum of education and income. Forty-two percent of the women met current recommendations for moderate or vigorous physical activity; 48% were insufficiently active; and 9% were inactive. The following groups of women were more likely to be physically active: women with at least a high school education; women with perceived good health; women who knew people who exercise; and women who viewed the neighborhood as safe. These findings were statistically significant. CONCLUSIONS Interventions that target urban African-American women must address the safety of the physical environment and personal and social environmental correlates of physical activity, and they should focus especially on inactive women who have less than a high school education or perceive themselves to be in poor health.

Correlates of physical activity in urban Midwestern Latinas

BACKGROUND Latinas (Latino women) are at higher risk than non-Latina white women of cardiovascular disease and stroke, primarily because of higher rates of obesity and type-2 diabetes mellitus. Increases in physical activity help control these cardiovascular risk factors, but a higher percentage of Latinas than white women are inactive. The study goals were to identify personal, social environmental, and physical environmental correlates of physical activity of urban-dwelling, Midwestern Latinas and to obtain their recommendations for increasing exercise in their communities. METHODS A face-to-face interview (Women and Physical Activity Survey) that covered personal, social environmental, and physical environmental correlates of physical activity was performed with 300 volunteer Latinas (242 in Spanish, 58 in English), aged 20 to 50 years, living in Chicago. Physical activity was measured with questions on lifestyle and planned leisure activity (exercise) from the Behavioral Risk Factor Surveillance System survey. RESULTS The sample consisted of urban-dwelling Latinas who were primarily from Mexico and who spoke predominantly Spanish. The breakdown was as follows: 36% met current recommendations for moderate or vigorous physical activity, 52.3% were insufficiently active, and 11.7% were inactive. Physical activity was higher among younger women, married women, and women with the following characteristics: had some confidence about becoming more active, saw people exercising in the neighborhood, attended religious services, or lived in areas with heavy traffic. CONCLUSIONS Interventions need to focus on encouraging Latinas, especially those who are older, to reach the level of physical activity recommended to benefit health. The church may be a suitable community setting for initiating programs that provide women with the knowledge, skills, and motivation to become more active so that they can bring back to the larger Latina community.

Outcomes of a Home-Based Walking Program for African-American Women

Purpose. As compared with minimal treatment (MT), to determine the effectiveness of a home-based walking intervention enhanced by behavioral strategies targeted and tailored to African-American women (enhanced treatment [ET]) on adherence, physical activity, fitness, and body composition at 24 and 48 weeks. Design. Using a quasi-experimental design, treatments were randomly assigned to one of two community health centers. Setting. The centers were in predominately African-American communities. Participants. Sedentary women (156 ET, 125 MT) 40 to 65 years were recruited within a 3-mile radius of each center. Intervention. Both treatments had the same orientation. The ET group had four targeted workshops followed by weekly tailored telephone calls over 24 weeks. Methods. Generalized linear mixed models were used to test effects of treatments on adherence, physical activity, aerobic fitness, and body composition. Results. Adherence was significantly higher in the ET than the MT group and was related to the number of workshops attended (r = .58) and tailored calls (r = .25) received. On-treatment analysis showed significant postintervention improvement in waist circumference and fitness in the ET group; however, these improvements were not statistically different between the two groups. Intent to treat analysis showed a significant increase in fitness, decrease in waist circumference, and no change in body mass index in both treatments. Conclusion. Findings suggest the potential impact of workshop group support on adherence in African-American women.

Psychosocial risk factors for work‐related musculoskeletal disorders of the lower‐back among long‐haul international female flight attendants

AIM This paper is a report of a study to examine the relationships between work-related psychosocial factors and lower-back work-related musculoskeletal disorders among long-haul international female flight attendants. BACKGROUND Recent attention has focused on the influence of work-related psychosocial factors on work-related musculoskeletal disorders. To date, however, little is known about the influence of psychosocial factors at work on lower back work-related musculoskeletal disorders in female flight attendants. METHOD A cross-sectional, mailed survey was conducted in 2004 with flight attendants in one major airline who were randomly selected from a union membership list. The work-related psychosocial factors included psychological job demand, decision latitude, social support, job insecurity, and external environmental concerns. Physical load was defined by overall strenuousness across 41 job tasks and measured by a 4-point scale of strenuousness. Lower-back work-related musculoskeletal disorders were defined as lower-back symptoms that occurred at least once a month or lasted at least 1 week in the past year and caused at least moderate pain. FINDINGS The flight attendants with lower back work-related musculoskeletal disorders, compared with those without lower-back work-related musculoskeletal disorders, had higher perceived psychological job demands, job insecurity, and physical load. After controlling for physical load and personal factors, high job insecurity significantly increased the risk for lower-back work-related musculoskeletal disorders. CONCLUSION Occupational health nurses in the airline industry should be cognizant of the importance of assessing the influence of both job tasks and work-related psychosocial factors on lower-back work-related musculoskeletal disorders.

The frequency of cerebral microbleeds increases with CHADS(2) scores in stroke patients with non-valvular atrial fibrillation.

Cerebral microbleeds (CMBs) are extravasations of blood from lipohyalinized or amyloid angiopathic cerebral arterioles, and the presence and numbers of CMBs are significantly associated with the development of oral anticoagulation (OA)‐related intracranial haemorrhage (ICH). The aim of this study was to investigate whether there is a difference in CMBs burden according to CHADS2 scores or CHA2DS2‐VASc scores in non‐valvular atrial fibrillation (NVAF) patients.

Factors associated with needlestick and sharp injuries among hospital nurses: A cross-sectional questionnaire survey

BACKGROUND The current status of needlestick or sharp injuries of hospital nurses and factors associated with the injuries have not been systematically examined with representative registered nurse samples in South Korea. OBJECTIVE To examine the incidence to needlestick or sharp injuries and identify the factors associated with such injuries among hospital nurses in South Korea. DESIGN, SETTINGS AND PARTICIPANTS A cross-sectional survey of hospital nurses in South Korea. Data were collected from 3079 registered nurses in 60 acute hospitals in South Korea by a stratified random sampling method based on the region and number of beds. METHODS The dependent variable was the occurrence of needlestick or sharp injuries in the last year, and the independent variables were protective equipment, nurse characteristics, and hospital characteristics. This study employed logistic regression analysis with generalized estimating equation clustering by hospital to identify the factors associated with needlestick or sharp injuries. RESULTS The majority (70.4%) of the hospital nurses had experienced needlestick or sharp injuries in the previous year. The non-use of safety containers for disposal of sharps and needles, less working experience as a registered nurse, poor work environments in regards to staffing and resource adequacy, and high emotional exhaustion significantly increased risk for needlestick or sharp injuries. Working in perioperative units also significantly increased the risk for such injuries but working in intensive care units, psychiatry, and obstetrics wards showed a significantly lower risk than medical-surgical wards. CONCLUSIONS The occurrence of needlestick or sharp injuries of registered nurses was associated with organizational characteristics as well as protective equipment and nurse characteristics. Hospitals can prevent or reduce such injuries by establishing better work environments in terms of staffing and resource adequacy, minimizing emotional exhaustion, and retaining more experienced nurses. All hospitals should make safety-engineered equipment available to registered nurses. Hospitals as well as specific units showing higher risk for needlestick and sharp injuries should implement organizational strategies to prevent such injuries. It is also necessary to establish a monitoring system of needlestick and sharp injuries at a hospital level and a reporting system at the national level in South Korea.

Quality of nursing doctoral education in Korea: towards policy development

AIMS This article is a report on an international study of the quality of nursing doctoral education; herein, we report findings for Korea. Specific aims were to: examine the validity and reliability of the quality of nursing doctoral education questionnaire; and identify contributing factors and domain(s) for improvement. BACKGROUND The quality of nursing doctoral education has been a worldwide concern with the recent rapid increase in number of nursing doctoral programmes around the world, and comprehensive evaluation is needed for policy recommendations. METHODS A cross-sectional descriptive study, conducted from October 2006 to January 2007, used an online questionnaire evaluating four domains: programme, faculty, resources and evaluation. Seven deans, 48 faculty, 52 graduates and 87 students from 14 nursing schools participated. RESULTS Content and construct validity, and construct reliability of the questionnaire were established. Overall, participants reported that the perceived quality of private universities/schools was significantly higher than that of public/national universities. A higher ratio of doctoral to non-doctoral students was significantly associated with higher quality. The domains of programme, faculty and resources were highly correlated. The programme was the most important domain; availability of sufficient materials and information for students most needed improvement. Overall, faculty perceived the quality of the programme, faculty and resources as more positively than did the graduates and students. CONCLUSION This study provides useful policy guidance for nurse educators worldwide for improving doctoral programmes and facultys role in educating students. Further study is recommended that examines contributing factors to quality doctoral education.

Self‐management program for obesity control among middle‐aged women in Korea: A pilot study

AIM The aim of this study was to determine the effectiveness of a 12 week self-management intervention program, as compared to a structured exercise intervention, for obesity control among middle-aged women in Korea. METHODS A quasi-experimental study was conducted with 27 women in a self-management group and 24 in a structured exercise group for 12 weeks. The self-management group received interventions that included walking at a convenient time and place, keeping healthy dietary habits, group workshops, phone counseling, and mobile phone short message services. The structured exercise group received a structured exercise intervention, which involved three 1 h walking classes per week at the health center. Both groups received baseline assessments before starting the interventions and at 12 weeks. The data were analyzed by using two sample t-tests, a paired t-test, and the χ(2) -test. RESULTS After 12 weeks, there were significant changes in the health behavior, amount of body fat, and blood pressure of the participants in both intervention groups, but there was no significant difference in their body composition, blood profile, or blood pressure. CONCLUSION Both the self-management and the structured exercise programs were effective in controlling obesity in middle-aged obese women in Korea. However, considering the chronic nature of obesity, the self-management program would be more beneficial, compared to the structured exercise program, as it allows people to exercise at a convenient time and place and to learn how to cope with their lifestyle barriers.

Psychosocial Factors and Work-related Musculoskeletal Disorders among Southeastern Asian Female Workers Living in Korea

Objectives A rapid increase in the population of migrant workers in Korea has brought new challenges regarding the possible effects of acculturation on health. The purpose of this study was to examine the influence of acculturation- and work-related psychosocial factors on work-related musculoskeletal disorders among migrant female workers living in Korea. Methods A cross-sectional survey design was used. A translated, structured questionnaire was administrated to 156 southeastern Asian female full-time workers living in Korea. Results About 35% of the participants experienced some type(s) of work-related musculoskeletal disorder(s), which were more prevalent in Vietnamese women than in Thai and Filipino women. Women who preferred to maintain their own heritage and to reject the host country heritage were at risk for work-related musculoskeletal disorders. Conclusion Acculturation strategy and nationality were found to be significant factors associated with work-related musculoskeletal disorders. Health professionals need to accommodate acculturation contexts into risk assessment and intervention development for work-related musculoskeletal disorders separately for different nationalities.

[Influence of self efficacy, social support and sense of community on health-related quality of life for middle-aged and elderly residents living in a rural community].

PURPOSE The purpose of this study was to examine the relationship between self-efficacy, social support, sense of community and health-related quality of life (HRQoL), including the direct and indirect effects of the variables on HRQoL. METHODS A cross-sectional survey was conducted with a convenience sample of 249 middle-aged and elderly residents living in a rural community in A-County, K Province. The structured questionnaire included 4 scales from the Euro Quality of life-5 Dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression), and measures of General Self-Efficacy, Social Support, and Sense of Community. Data were analyzed using SPSS WIN 20.0 and AMOS 21.0 program. RESULTS The mean HRQoL score for the participants was 0.87±0.13. Self-efficacy (β=.13, p=.039) and age (β= -.38, p<.001) were significantly associated with HRQoL, explaining 21% of the variance. In the path analysis, self-efficacy showed a significant direct effect on HRQoL (β=.14, p=.040) and significantly mediating relationships between both social support (β=.05, p=.030) and sense of community (β=.02, p=.025) and HRQoL. CONCLUSION Although self-efficacy was found to be the main predictor for HRQoL, the findings imply that social environmental factors such as social support and sense of community need to be considered when developing interventions to increase HRQoL in middle-aged and elderly residents in rural communities.
