Testing the efficacy of the theory of planned behavior to explain strength training in older adults

The purpose of this study was to use the constructs of the theory of planned behavior (TPB) to gain a better understanding of the factors influencing older adults' participation in strength training. Two hundred men and women age 55 years and older were purposely sampled from seniors' centers in Ontario Canada. Participants completed a TPB questionnaire and reported their current physical activity participation. It was hypothesized that perceived behavioral control followed by attitude would be the strongest determinants of strength-training intentions and that intention would be the strongest determinant of strength-training behavior. Regression analyses revealed that subjective norm and perceived behavioral control explained 42% of the variance in intention and intention explained 40% of the variance in behavior. Gender and current strength-training participation did not significantly moderate the relationship between the TPB variables. The results suggest that interventions targeting subjective norm and perceived control might be helpful in promoting strength-training behavior among older adults.     

Continuity of care for youth in foster care with serious emotional disturbances

Continuity of mental health care has long been considered an essential component to the delivery of a high-quality mental health services, particularly for children with special needs. Unfortunately, discontinuities in care are common for children in foster care due in part to placement instability, disruptions in health coverage, and the fragmented health system. This retrospective cohort study examined factors associated with continuity of care for youth (aged 5–17 years) in foster care diagnosed with schizophrenia and bipolar disorder. Information on individual-level (demographic and clinical characteristics) and contextual-level variables (county socio-demographic and health care resources) were abstracted from Medicaid claim files and the Area Resource File. Continuity of care was defined as regularity of care—utilization of at least one outpatient mental health visit per month during the year. Multilevel modeling was used to assess the association between individual and contextual-level variables and continuity of care. Of the 952 youth in the study sample, 439 (46.1%) received regular monthly outpatient visits over the 1 year follow-up period. The odds of receipt of regular outpatient treatment were associated with prior outpatient care (odds ratio (OR): 7.43, 95% confidence interval (CI): 2.60–21.20), the presence of a chronic medical illness (OR: 1.45, 95% CI: 0.98–2.16), comorbid anxiety (Or: 1.76, 95% CI 1.22–2.53), or conduct disorder (OR: 1.57, 95% CI: 1.13–2.18), and the use of multiple psychotropic medications as compared to no medications (OR: 1.55, 95% CI: 1.08–2.23). The odds of receiving regular outpatient treatment were higher for youths who resided in suburban areas as compared to metropolitan areas (OR: 1.97, 95% CI: 1.04–3.73) and for those who resided in areas with greater supply of psychiatrists per capita (OR: 1.22, 95% CI: 1.02–1.45). Study findings underscore the need for quality improvement initiatives that improve access to care, care coordination, and continuity of care.     

Mapping the Elder Mistreatment Iceberg: U.S. Hospitalizations With Elder Abuse and Neglect Diagnoses

Purpose: This study describes U.S. hospitalizations with diagnostic codes indicating elder mistreatment (EM). Method: Using the 2003 Nationwide Inpatient Sample (NIS) of the Healthcare Costs and Utilization Project (HCUP), inpatient stays coded with diagnoses of adult abuse and/or neglect are compared with stays of other hospitalized adults age 60 and older. Results: Few hospitalizations (< 0.02%) were coded with EM diagnoses in 2003. Compared to other hospitalizations of older adults, patients with EM codes were twice as likely to be women (OR = 2.12, 95% CI = 1.63–2.75), significantly more likely to be emergency department admissions (78.0% vs. 56.8%, p < .0001), and, on average, more likely to have longer stays (7.0 vs. 5.6 days, p = 0.01). Patients with EM codes were also three to four times more likely to be discharged to a facility such as a nursing home rather than “routinely” discharged (i.e., to home or self-care) (OR = 3.66, 95% CI = 2.92–4.59). Elder mistreatment–coded hospitalizations compared to all other hospitalizations had on average lower total charges ($21,479 vs. $25,127, p < .001), with neglect cases having the highest charges in 2003 ($29,389). Implications: Knowledge about EM is often likened to the “tip of the iceberg.” Our study contributes to “mapping the EM iceberg”; however, findings based on diagnostic codes are limited and should not be used to minimize the problem of EM. With the so-called graying of America, training is needed in recognizing EM along with research to improve our nation's response to the mistreatment of our elderly population.     

Perceptions of the Neighborhood Environment Associated With Walking at Recommended Intensity and Volume Levels in Recreational Senior Walkers

This study examined the relationship of perceived neighborhood environment factors with recommended volume and intensity of walking in recreational senior walkers. A sample of 85 seniors used an accelerometer and completed the ALPHA questionnaire. Binomial logistic regressions were conducted to detect associations. Perceptions about traffic safety (odds ratio [OR] = 4.395; 95% confidence interval [CI] = 1.024; 18.866) and pleasant environment (OR = 8.718; 95% CI = 1.803; 42.149) were positively related with the achievement of 10,000 steps per day, in older women. The perception of nearby parks was positively associated with the compliance with peak 30-minutes cadence above 100, in older men (OR = 14.353; CI 95% = 1.321; 15.591). No more significant associations were found between perceptions of the neighborhood environment and walking at recommended intensity and volume levels. These results indicated that community initiatives that encourage traffic safety, pleasant environment, and parks may be a promising direction to promote walking at recommended volume and intensity in senior walkers.     

Intimate partner violence: prevalence and risk factors for men in Cape Town, South Africa

This study examined the prevalence of and risk factors for intimate partner physical violence against women. Interviews were conducted with a sample of 1,378 men working in Cape Town municipalities. An average of 42.3% (95% CI: 39.6, 44.8) reported physical violence against a partner of the last 10 years, and 8.8% (95% CI: 7.3, 10.3) reported physical violence in the past year. After adjustment for age, occupational group, and race, the factors associated with use of violence against partners of the last 10 years were having no post-school training (OR = 2.10), witnessing parental violence in childhood (OR = 1.87), involvement in fights at work (OR = 2.73) and in communities (OR = 1.54), drug use (OR = 1.99), problem alcohol use (OR = 1.98), perceiving hitting women to be acceptable (OR = 4.54), frequent conflict (OR = 2.40), women's alcohol use (OR = 2.25), conflict about sex (OR = 2.16), and conflict about his infidelity (OR = 2.81). The study shows that ideas supportive of gender inequality and normative use of violence in different settings are major underlying factors for men's violence against partners.     

Designing a “Think-Along Dwelling” for People With Dementia: A Co-Creation Project Between Health Care and the Building Services Sector

Ageing-in-place is the preferred way of living for older individuals in an ageing society. It can be facilitated through architectural and technological solutions in the home environment. Dementia poses additional challenges when designing, constructing, or retrofitting housing facilities that support ageing-in-place. Older adults with dementia and their partners ask for living environments that support independence, compensate for declining and vitality, and lower the burden of family care. This study reports the design process of a demonstration home for people with dementia through performing a literature review and focus group sessions. This design incorporates modifications in terms of architecture, interior design, the indoor environment, and technological solutions. Current design guidelines are frequently based on small-scale studies, and, therefore, more systematic field research should be performed to provide further evidence for the efficacy of solutions. The dwellings of people with dementia are used to investigate the many aspects of supportive living environments for older adults with dementia and as educational and training settings for professionals from the fields of nursing, construction, and building services engineering.     

Declining negative consequences related to alcohol misuse among students exposed to a social norms marketing intervention on a college campus

OBJECTIVE: The authors examined whether alcohol-related negative consequences decreased among students exposed to an intervention. PARTICIPANTS: Beginning in 1999, approximately 2,500 randomly selected undergraduates from a 4-year US university annually participated in a Web-based survey over 6 years. METHODS: The educational intervention used social norms initiatives. Main outcome measures included recall of intervention, estimated blood alcohol content (eBAC) when drinking, and 10 negative consequences from alcohol within the past year. RESULTS: First-year students recalling exposure had lower odds of negative consequences (odds ratio [OR] = 0.78, 95% confidence interval [CI] = 0.64-0.95) and of having an eBAC higher than .08 (OR = 0.76, 95% CI = 0.62-0.92). Over the 6 study years, the odds among all participants of experiencing (a) none of 10 alcohol consequences nearly doubled (OR = 2.13, 95% CI = 1.82-2.49) and (b) multiple consequences decreased by more than half (OR = 0.43, 95% CI = 0.36-0.50). CONCLUSIONS: These findings have important implications for US colleges and universities engaged in the reduction of harm associated with alcohol misuse.     

Differences in Tobacco Use Among Two-Year and Four-Year College Students in Minnesota

Abstract

Objective: This study compares tobacco use rates among two-year and four-year college students and explores the demographic variables that predicted that behavior. Participants: 9,931 students at 14 two-year and four-year colleges in Minnesota participated. Methods: Students at 11 schools completed an online survey, and students at 3 schools completed a paper survey in 2007. Results: After controlling for sex, age, ethnicity, relationship status, hours of work per week, and number of school credits, attending a two-year college predicted current and daily smoking (odds ratio [OR]) = 1.70, 95% confidence interval [CI] = 1.52–1.89; OR = 3.47, 95% CI = 2.94–4.11) and smokeless tobacco use (OR = 1.65, 95% CI = 1.32–2.06; OR = 1.64, 95% CI = 1.06–2.53). Conclusions: Although two-year college students comprise approximately two fifths of the college student population, surveys of college student tobacco use have focused nearly exclusively on four-year college students. Two-year college students should represent a priority population for tobacco control because attending a two-year college predicts increased tobacco use.     

The impact of childhood sexual abuse and intimate partner violence on sexually transmitted infections

Childhood sexual abuse (CSA) and adult intimate partner violence (IPV) have both been found to be associated with sexually transmitted infections (STIs) independently, but studies of STIs have rarely looked at victimization during both childhood and adulthood. This paper examines the relationship between CSA, IPV and STIs using data from a nested case-control study of 309 women recruited from multiple health care settings. Overall, 37.3% of women experienced no violence, 10.3% experienced CSA only, 27.3% experienced IPV only, and 25.0% experienced both CSA and IPV. Having ever been diagnosed with an STI was associated with violence (CSA only, odds ratios [OR] = 2.8, 95% confidence intervals [CI] = 1.0-7.5; IPV only, OR = 2.2, 95% CI = 1.0-4.9; CSA and IPV: OR = 4.0, 95% CI = 1.7-9.4), controlling for demographic characteristics. Women who experienced CSA were younger when they were first diagnosed. Understanding how both childhood and adult victimization are associated with diagnosis of STIs is important to reducing the incidence and prevalence of STIs, as well as the associated consequences of STIs.     

Environmental changes to increase physical activity: perceptions of older urban ethnic-minority women

Despite the numerous benefits of physical activity, older adults continue to be more sedentary than their younger counterparts, and sedentary behavior is more prevalent among older racial and ethnic minorities than among Whites. This study used the nominal group technique (NGT) to examine participants' perceptions of what neighborhood environmental changes would encourage greater physical activity for older African American and Hispanic women. Participants age 50-75 years were recruited from 2 urban community health clinics. Nine NGT sessions (45 participants) were conducted. The women were asked what changes in their neighborhood environment would encourage them to become more physically active. Responses to the research question were tabulated, and qualitative analysis was used to identify themes and categories. Major categories were physical environment changes, safety, and activities/social support. Although the physical environment received the greatest number of points, concerns for personal safety cut across categories. Participants indicated the need for more facilities in which to be active.

Conclusions: These findings have important implications for US colleges and universities engaged in the reduction of harm associated with alcohol misuse.     

Green Care Farms Promote Activity Among Elderly People With Dementia

In the Netherlands, an increasing number of green care farms are providing day care to community-dwelling elderly people with dementia. Currently, it is unknown whether activities, activity participation, and facility use of elderly people with dementia at green care farms differ from those at regular day care facilities. The authors performed group and individual observations at 11 green care farms and 12 regular day care facilities. Activities of elderly people at green care farms were more frequent, occurred outdoors more often, were of a higher physical intensity, and more often were aimed at individuals than activities at regular day care facilities. Therefore, the green care farms’ environment may be more beneficial for elderly people with dementia than the regular day care facility environment.     

Effects of beverage-specific alcohol consumption on drinking behaviors among urban youth

Alcoholic beverage consumption among high school students has shifted from beer to liquor. The current longitudinal study examined the effects of beverage-specific alcohol use on drinking behaviors among urban youth. Data included 731 adolescents who participated in Project Northland Chicago and reported consuming alcohol in 7th grade. Logistic regression tested the effects of beverage-specific use on consequences (e.g., alcohol use in the past month, week, heavy drinking, and ever drunkenness). Compared to wine users, adolescents who reported drinking hard liquor during their last drinking occasion had increased odds of alcohol use during the past month (OR = 1.44; 95% CI = 1.01-2.05), past week (OR = 3.37; 95% CI = 1.39-8.18), and ever drunkenness (OR = 1.56; 95% CI = 1.07-2.29). Use of hard liquor was associated with increased risk of alcohol-related consequences. Early selection of certain alcoholic beverages (e.g., hard liquor) may result in negative health outcomes and problematic alcohol use over time.     

Occupational lifting tasks as a risk factor in low back pain: a case-control study in a Mexican population

The objective of this study was to quantify and assess whether lifting tasks in the workplace are a risk factor in lumbar spondyloarthrosis etiology. A case-control study was performed with 231 workers, 18-55 years old, insured by the Mexican Social Security Institute (IMSS, according to its designation in Spanish). A multivariate analysis using conditional logistical regression showed that lifting tasks, combined with driving tasks, are associated with this illness (OR = 7.3; 95% CI 1.7-31.4). The daily frequency of lifting as it interacts with work as a driver resulted in a greater risk (OR = 10.4; 95% CI 2.0-52.5). The load weight, daily task-hours and cumulative time showed a dose-response relationship. The attributable risk for lifting tasks was 0.83, suggesting that 83% of lumbar spondyloarthrosis development could be prevented if risk factors were eliminated by ergonomic redesign of the task.     

Working Beyond the Traditional Retirement Age: The Influence of Health on Australia’s Older Workers

This article examines the relationship between health and workforce participation beyond the age of 65 years in Australia. This study found that people with a chronic health condition were less likely to be employed than those without a health condition (OR, 0.59; 95% CI [0.38, 0.92]). Among those with a chronic health condition, those in income quartile 2 (OR, 0.27; 95% CI [0.11, 0.67]) and 3 (OR, 0.38; 95% CI, [0.15–0.93]) were significantly less likely to be employed relative to those in income quartile 4. Older workers with a chronic health condition were less likely to work beyond the age of 65; however, among those with a chronic health condition, those with very high income and those with very low income were the most likely to keep working.     

The effects of physical therapists' guidance on improvement in a strength-training program for the frail elderly

Elderly participants experiencing difficulty in chair rising and with a maximum knee-extensor torque below 87.5 N . m were randomized to different versions of a strength-training program for the knee-extensors: to a high-guidance group (HG; two group sessions supervised by a physical therapist and one unsupervised home session per week, n = 17), a medium-guidance group (MG; one supervised group session and two unsupervised home sessions per week, n = 16), or a control group (C; no exercise, n = 16). Maximal isometric knee strength increased more in HG than in C (p = .03) and with increasing guidance (p = .03). The effect was mainly the result of participants with low initial strength. Walking speed increased more for HG than for C (p = .02) and than for MG (p = .06). No statistically significant improvements were seen on other functional tests. In summary, the study shows a trend toward better results with more supervision, but more and larger studies are needed to confirm this.     

Resistive training and long-term function in older adults

The purpose of this study was to evaluate the effects of a 24-month moderate-intensity resistive-training intervention on strength and function in older adults. A repeated-measures experimental research design was employed as a sample of 55 apparently healthy, older, community-dwelling volunteers (30 exercisers- 25 women and 5 men; 25 comparisons- 16 women and 9 men) were evaluated for strength of 5 muscle groups that influence lower extremity movement and physical function. Strength and function were evaluated at 6-month intervals. The findings from this study indicate that a moderate-intensity resistive-training program increases strength in older adults and that the strength benefits are retained for the duration of the intervention. Furthermore, a long-term strength-training program can increase independent-function skills in older adults and might therefore aid in prolonging functional independence.     

Effects of strength and power training on neuromuscular variables in older adults

The purpose of this study was to compare the neuromuscular adaptations produced by strength-training (ST) and power-training (PT) regimens in older individuals. Participants were balanced by quadriceps cross-sectional area (CSA) and leg-press 1-repetition maximum and randomly assigned to an ST group (n = 14; 63.6 ± 4.0 yr, 79.7 ± 17.2 kg, and 163.9 ± 9.8 cm), a PT group (n = 16; 64.9 ± 3.9 yr, 63.9 ± 11.9 kg, and 157.4 ± 7.7 cm), or a control group (n = 13; 63.0 ± 4.0 yr, 67.2 ± 10.8 kg, and 159.8 ± 6.8 cm). ST and PT were equally effective in increasing (a) maximum dynamic and isometric strength (p < .05), (b) increasing quadriceps muscle CSA (p < .05), and (c) decreasing electrical mechanical delay of the vastus lateralis muscle (p < .05). There were no significant changes in neuromuscular activation after training. The novel finding of the current study is that PT seems to be an attractive alternative to regular ST to maintain and improve muscle mass.
