Determining the Long-Term Effectiveness of a Group-Based Physical Activity Program.

OBJECTIVE: In 2015, only half (48%) of older adults in the United States (≥60 years) reported engaging in any kind of physical activity. Few studies examine the impact of evidence-based programs when adopted in community-based settings. The purpose of this study is to assess the effectiveness of EnhanceFitness (EF) upto 12-months. METHOD: EF was offered to older adults in South Florida. A total of 222 EF classes were offered between October 2008 and December 2014. Program consisted of a 1-hour session held three times a week. Even though participation was required for 4 months, 1,295 participants continued the program for at least 1 year. RESULTS: All participants showed significant improvement in outcome measures. A mean change of 1.5, 1.7, and 1.9 was seen in number of chair stands at 4, 8, and 12 months (p < .001), respectively. The number of arm curls performed improved from 16.8 at baseline to 18.8, 18.8, and 19.2 at 4-, 8-, and 12-months, respectively. Participants improved their up-and-go time by decreasing from 9.1 (baseline) to 8.7 (4 months) to 8.6 (12 months; p = .001). DISCUSSION: Randomized controlled trials are commonly used to determine the efficacy of an intervention. These interventions when disseminated at the population level have the potential to benefit large masses. EF is currently offered at more than 700 locations. This tremendous success of EF brings attention to an important question of continuous monitoring of these programs to ensure program consistency and intended outcomes. The model used by the Healthy Aging Regional Collaborative could be replicated by other communities.

A needs assessment of health department employees in Puerto Rico and Florida.

Public health training centers were established to enhance competencies in skills required to meet 21st-century public health challenges. In 2011, the Puerto Rico-Florida Public Health Training Center conducted surveys to assess the training needs of two populations of public health workers serving Hispanic communities: Florida Department of Health employees and workers at the regional and central offices of the Puerto Rico Department of Health. The two surveys were similar, but not identical in content and administration. A 52.6% response rate was achieved in the Commonwealth of Puerto Rico, where limited computer access necessitated use of a pen-and-paper survey. A 20.7% response rate was achieved in Florida, where an online survey was used and incomplete responses were problematic. Puerto Rico respondents (n = 1,414) were similar in age (Mdn age = 48 years) to Hispanic Florida respondents (n = 546, Mdn age =45 years). They also reported higher levels of academic achievement and more years of experience in public health. Nevertheless, self-assessed public health competency scores were in the low- to mid-range for Hispanic respondents in both locales. Although self-assessed training priorities differed, Hispanic employees in both jurisdictions preferred hands-on and face-to-face training to distance learning. Findings indicate a need for training based on adult learning theory, targeted to entry-level employees, and addressing the top five self-assessed training needs, especially health promotion and disease prevention and public health law and policy, which emerged as priority training areas in both survey populations.

Lessons from the fields: a migrant HIV prevention project.

Migrant and seasonal workers are vulnerable to human immunodeficiency virus (HIV) due to poverty, inadequate knowledge of preventive strategies, and lack of access to health care. This study addresses the disparate impact of HIV among Hispanic and African American migrant workers in Immokalee, Florida, who use alcohol and other drugs. Through pilot testing to adapt the experimental and comparison interventions to these two distinct populations, research staff have learned the importance of (1) establishing and maintaining trust between outreach staff and the migrant community; (2) being aware of cultural nuances and practices that might create challenges to the research process, and the interaction of these factors with poverty; and (3) having flexibility in recruitment and intervention. As one of the first intervention studies in this population to use an experimental design and to focus on the social and contextual factors that contribute to risky behaviors, these lessons may provide guidance for future researchers.

HIV-Related Stigma, Quality of Care, and Coping Skills: Exploring Factors Affecting Treatment Adherence Among PLWH in Haiti.

Stigma is a primary barrier to care and support for people living with HIV (PLWH). We explored relationships between HIV-related stigma and treatment adherence and the effects of psychological and structural factors on these relationships. HIV treatment adherence, stigma, and coping strategies were measured with questionnaires. Participants included 285 PLWH in Haiti. Multivariable linear regression was used to estimate predictors of treatment adherence. Structural equation modeling was used to determine whether relationships between stigma and treatment adherence variables were mediated by coping variables. Mean adherence was 93.1%; 72.3% of participants reported ≥ 95% adherence. Perceived stigma and quality-of-care satisfaction scores significantly predicted treatment adherence. Maladaptive coping did not act as a mediator between perceived stigma and treatment adherence, which could be due to stronger effects of perceived stigma on treatment adherence. Our study may help to improve treatment adherence and the care and quality of life for PLWH.

Alcohol Use and Sexual Risk Behaviors in a Migrant Worker Community.

There are not many studies exploring the association between alcohol use and risky sexual behaviors among migrant workers. This study analyzed how changes in alcohol use was associated with changes in risky sexual behavior and psychosocial variables. Data for this study was drawn from an HIV risk reduction project. Repeated measures ANOVA and Linear mixed model statistical method was conducted to find changes and association between alcohol use, sexual risk and psychosocial variables over time. The sample (n = 203) was composed of African Americans (33.0 %) and Hispanics (77.0 %) men. Both groups, over time, showed reduction in sexual risk in accordance with reduction in alcohol use. Changes in alcohol use and psychosocial variables showed significant association with sexual risk changes over time. Psychological strategies like building social support should be considered for HIV risk reduction intervention directed towards high alcohol consuming migrant workers.

Structural Characteristics of Migrant Farmworkers Reporting a Relationship with a Primary Care Physician.

Migrant farmworkers are disproportionately affected by many adverse health conditions, but access healthcare sparingly. This study of migrant farmworkers examined the distribution and general characteristics associated with having access to healthcare. Access to healthcare was measured by asking whether the participants (N = 413) had a primary care physician. Majority of participants did not have a primary care physician. Female migrant workers (AOR = 2.823 CI: 1.575-4.103) with insurance (AOR = 6.183 CI: 4.956-11.937) who lived at study site for more than 5 years (AOR = 2.728 CI: 1.936-7.837) and born in the United States (AOR = 2.648 CI: 1.373-3.338) had greater odds to have a primary care physician than recent male migrants without insurance who were born outside United States. There is a need to focus on Community Health Centers and Migrant Health Centers in tailoring their services and to widen the implementation and improve funding of Accountable Care Organizations to improve access to care of migrant farmworkers.

Relationship Between Metabolic Syndrome and Cognitive Abilities in U.S. Adolescents.

BACKGROUND: Metabolic syndrome is increasingly common in U.S. adolescents and has been linked to cognitive dysfunction. Purpose of this study is to explore associations between metabolic syndrome and cognitive impairment in U.S. adolescents using population-based data. STUDY DESIGN: Participants included adolescents aged 12-16 years who participated in the National Health and Nutrition Examination Survey (NHANES) III. The main outcome measures included assessments of cognitive function using Wide Range Achievement Test-Revised (WRAT-R) and Wechsler Intelligence Scale for Children-Revised (WISC-R) tools. The WRAT-R consisted of mathematics and reading tests. The WISC-R consisted of block design test, which measures spatial visualization and motor skills, and digit span test, which measures working memory and attention. Linear regression models were used to examine associations between metabolic syndrome and cognitive function. We used education levels of the family reference person, while controlling for education levels because of missing data. RESULTS: Presence or absence of metabolic syndrome was tested in 1170 of 2216 NHANES III participants aged 12-16 years. Regression models showed that participants with metabolic syndrome scored an average 1.25 [95% confidence interval (CI) = -2.14 to -0.36] points lower in reading examination and an average 0.89 (95% CI = -1.65 to -0.13) points lower in digit span examination, compared to those without metabolic syndrome. In addition, components of metabolic syndrome-elevated systolic blood pressure and increased waist circumference (WC)-were associated with impaired working memory/attention, and higher fasting glucose and increased WC were associated with poorer reading test scores. CONCLUSIONS: Metabolic syndrome was associated with impaired reading, working memory, and attention among adolescents.

Satisfaction with access to health care among injection drug users, other drug users, and nonusers.

This article examines the satisfaction of users of cocaine and/or opiates and non-drug users with access to the health care system. Data were obtained from a sample of 1,477 injection drug users, non-injection drug users, and non-drug users recruited from neighborhoods with high drug use. Multiple regression examined the relationship between satisfaction with access to health care and demographic, health status and health care utilization, ability to pay, and alcohol and drug use variables. Age, ethnicity, health status, having received health care in the last 12 months, not having received health care when needed, having received preventive health care, health insurance, and drug use were independently associated with satisfaction. Injection drug users and non-injection drug users were less satisfied with access to health care. The article discusses strategies to improve health care delivery to drug users.

Improving access to primary health care for chronic drug users: an innovative systemic intervention for providers.

An intervention was designed to improve access to primary care for chronic drug users (CDUs) by enhancing health care providers' knowledge and skills. Using a case study method, three study sites were systematically selected for intervention implementation: a primary care clinic (PC), an emergency department (ED), and a drug treatment (DT) facility. Participants completed pre- and postintervention tests of knowledge, skills, and intentions to practice. Compared with pretest scores, participants had significantly higher posttest scores concerning knowledge of CDUs' health care needs. Postintervention evaluations indicated intentions to practice skills learned in the intervention. As hypothesized, the PC and ED subsequently instituted formal screening mechanisms to identify CDUs. This intervention revealed potential to build bridges between health care providers and CDUs. By overcoming provider resistance, primary care access can be realized for this and other disadvantaged populations.

Risky sexual behaviors: The role of ethnic identity in HIV risk in migrant workers.

Migrant workers have been shown to be at a heightened level of risk for HIV, and ethnic identity has been posited to have an impact on engagement in risky sexual behaviors. Our longitudinal study examined associations between baseline and short-term changes in ethnic identity and high-risk sexual behaviors. Baseline (n = 431) and 6-month assessment (n = 270) data were obtained from a larger HIV prevention study conducted among African American and Hispanic migrant workers. Repeated-measures multivariate analysis of covariance and multiple linear regressions were used. Ethnic identity explore, a subscale of ethnic identity, was a significant predictor of overall sexual risk [F(8, 422) = 6.953, p < .001] and unprotected vaginal acts [F(8, 422) = 8.444, p < .001] at baseline. However, ethnic identity had no bearing on changes in risky sexual behaviors. Ethnic identity explore was associated with safer sexual behaviors.

Proficiency in condom use among migrant workers.

Consistent and correct use of condoms is important to prevent the transmission of HIV and other sexually transmitted diseases. We evaluated condom use skills on an 11-point scale in which participants were observed placing a condom on a penile model. Participants were 375 sexually active African American and Hispanic migrant workers. For analysis, subjects were divided into skilled and unskilled groups by a median split of the condom use skills score. Sexual risk behaviors were analyzed between condom use skilled and unskilled groups and level of condom use skills between African Americans and Hispanics. African Americans showed better skills in using condoms, and participants in the condom-use skilled group used condoms more frequently. Finally, a logistic regression was conducted to find predictors of condom use skills. Significant predictors were ethnicity, language, and assistance-related social support (obtaining advice from people who could provide tangible assistance).

Newcomer Status as a Protective Factor among Hispanic Migrant Workers for HIV Risk.

The HIV rate among U.S. migrant workers is 10 times that of the national rate. The highly unstable lifestyle of migrant workers places them at heightened vulnerability to sexually transmitted infections; hence, there is a need to investigate the attitudes and sexual risk factors that may play a protective role in the transmission of HIV in this population. This study examines the association between attitudes and HIV risk behaviors among Hispanic male and female migrant workers (n = 255) and their length of stay (shorter length of stay as a protective factor) in Immokalee, FL, USA. Pearson's correlation and regression analyses were utilized to analyze the relationship between HIV risk behaviors (intention to use condoms and alcohol use) with length of stay in Immokalee. Longer length of stay positively correlated with number of drinks (p < 0.05) and frequency of drinks (p < 0.01) and negatively correlated with ethnic identity search (p < 0.05). Regression analysis showed that length of stay predicted both behavioral intention to use condoms (p < 0.05) and alcohol consumption (p < 0.05). The findings suggest that migrant workers who are new to Immokalee may have a higher likelihood of practicing protective HIV risk behaviors and having more favorable attitudes toward risk reduction than long-timers. This study might provide important new evidence on the drivers of multiple concurrent and potential protective factors against risky sexual behaviors among Hispanic migrant workers.

Intermediate outcomes of chronic disease self-management program offered by members of the Healthy Aging Regional Collaborative in South Florida.

Currently, 80% of adults over the age of 65 have at least one chronic disease. The Chronic Disease Self-management Program (CDSMP) focuses on increasing self-efficacy for managing chronic disease. Few studies have evaluated the effectiveness of CDSMP when offered by multiple agencies, as a collaborative effort, in community-based settings. Seven agencies delivered 108 CDSMP workshops at 81 sites from October 1, 2008, to December 31, 2010. A total of 811 participants were eligible for analysis. Participants completed surveys at baseline and week 6, the end of instruction. Controlling for agency effect and general health at baseline, the general linear model was used to assess the significance of outcomes at 6 weeks. Outcomes showing significant improvement included self-efficacy to manage disease (p = .001), self-efficacy to manage emotions (p = .026), time spent walking (p = .008), and perceived social/role activities limitations (p = .001). Findings showed that CDSMP is an effective program at improving self-efficacy, increasing physical activity, and decreasing limitations.

Differences in HIV-related hospitalization among white, black, and Hispanic men and women of Florida.

Patients hospitalized for Human immunodeficiency virus (HIV) disease among the multi-ethnic population of Florida have been incompletely characterized to date. The objectives of the present study were to determine the race/ethnic (whites, blacks, Hispanics) differences in characteristics of patients by gender and the correlates of HIV-related mortality among them. A retrospective analysis of 9,113 discharge records (January to December 2001) with primary diagnosis of HIV disease was performed. Characteristics of patients in six sex-race/ethnic groups were compared using the X2 tests and multiple regression models. A multiple logistic regression modeling was used to evaluate the odds of HIV-related death associated with these characteristics. Approximately 64%, 23%, and 13% of records were for blacks, whites, and Hispanics, respectively. The adjusted length of stay (LOS) and hospital charges significantly differed only between black men and women. The insurance status, LOS, and age were significant correlates of HIV-related deaths. The potential causes of disparities between sex-ethnic groups of patients should be further explored.

A strategy for improving community effectiveness of HIV/AIDS intervention design: the Community Readiness Model in the Caribbean.

The Community Readiness Model (CR) offers a solution to the development of prevention strategies at the community level that makes use of community collaborations and community capacity. CR was administered in the U.S. Virgin Islands on St. Thomas, St. Croix, and St. John. All three islands scored lowest on dimensions of community climate and highest on knowledge of efforts to fight HIV/AIDS. The findings suggest that initial intervention efforts should improve the community climate of HIV/AIDS denial and stigma prior to introducing interventions that address HIV/AIDS risk behaviors. Community collaborators identify the interplay of social, structural, and political-economic factors for effective prevention.

HIV/AIDS Knowledge and Beliefs Among Haitian Adolescents in Miami-Dade County, Florida.

This study examined HIV/AIDS knowledge and beliefs in Haitian adolescents in an HIV epicenter, Miami-Dade Florida. This study examined survey data from 300 Haitian adolescents, aged 13 through 18, from both low-and middle-income neighborhoods. A sub-sample of 80 adolescents was selected for in-depth interviews and continuous observations with their families and networks of friends, which added rich descriptions to the quantitative data. Overall knowledge about HIV/AIDS was high with the majority of adolescents identifying unprotected sex and sharing injection drug needles as HIV transmission routes. Moreover, approximately 75% of the adolescents reported condom use as an effective preventive strategy. However, misconceptions that could reduce adolescents' adoption of HIV preventive strategies were also identified. The adolescents' sources for information about HIV/AIDS as well as implications for prevention interventions are discussed.

Technology trauma: barriers to increasing technology utilization.

While most social workers might agree that increasing the use of technology in agencies may be important for developing efficiency and effectiveness, little is known about the obstacles of doing so. In an NIDA-funded demonstration project to increase technology in agencies that serve drug abusing populations, researchers logged all email and memorandum communication for a two and a half year period. These communications documented the progress of the intervention from inception to implementation. Using a qualitative methodology, researchers for this analysis examined the communication documents, noting themes. A core theme focusing on barriers to implementing technology emerged from the data. These barriers included: agency personnel's lack of computer proficiency, lack of motivation for agency personnel to participate in the intervention, and agency personnel not following intervention protocols, having computer hardware and networking problems, the agency's physical structure (lack of space/computers), and the researchers/interventionists having restricted access to agency personnel.
