RESUMO

Objective: This analysis explored relationships between mental health symptoms and conditions and cognitive function in a cohort of Vietnam-era women veterans from the Health of Vietnam Era Veteran Women's Study (HealthViEWS). Methods: Vietnam-era women veterans completed a mail survey assessing self-reported symptom severity of posttraumatic stress disorder (PTSD) and depression. A telephone-based structured interview assessed mental health conditions and cognitive function (telephone interview for cognitive status [TICS]). Participants were categorized using a TICS threshold of ≤29 to designate possible cognitive impairment versus nonimpaired. Separate logistic regression models were used to determine associations between possible cognitive impairment and each self-reported and interviewer-rated assessment of PTSD and depression while adjusting for age, education, race, marital status, and wartime service location. Results: The sample consisted of 4,077 women veterans who were ≥60 years old and completed the TICS. Of these women, 7.20% were categorized with possible cognitive impairment. Logistic regression models indicated that self-reported PTSD and depression symptom severity were each significantly associated with higher odds of possible cognitive impairment (adjusted odds ratios [aOR]: 1.03 [95% confidence interval [CI]: 1.02-1.04] and 1.07 [95% CI: 1.04-1.09], respectively). Women veterans with a probable diagnosis of depression had higher odds of possible cognitive impairment compared to those without depression (aOR: 1.61 [95% CI: 1.07-2.42]). No association was found for probable diagnosis of PTSD. Conclusions: Although further examination remains necessary, results suggest that Vietnam-era women veterans with self-reported PTSD and depression symptom severity or a probable diagnosis of depression may benefit from screening of cognitive function to inform clinical care.

RESUMO

Background: Many Gulf War (GW) Veterans report chronic symptoms including pain, fatigue, and cognitive impairment, commonly defined as Gulf War Illness (GWI). Complementary and integrative health (CIH) therapies may potentially improve multiple symptoms of GWI. Objective: To examine the effectiveness of combining 2 commonly available CIH therapies, mindfulness meditation and auricular acupuncture, in improving health-related functioning and multiple symptom domains of GWI (e.g., pain, fatigue). Methods: This study was a randomized controlled trial in which Veterans with GWI were randomly assigned to either the intervention group (n = 75), wherein they received 2 distinct CIH therapies - mindfulness meditation and auricular acupuncture, or the active control group, wherein they received a GW Health Education (GWHE) program (n = 74), each lasting 8 weeks. Self-report health measures were assessed at baseline, endpoint, and 3 month follow-up. Results: In the intention-to-treat analyses, there were significant between-group differences for mental-health related functioning, fatigue, depression symptoms, and Kansas total severity scores for symptoms in which the CIH group had improved scores for these outcomes at endpoint compared to the GWHE group (all P ≤ .05). The CIH group also had significant reductions in pain interference at endpoint and follow-up compared to baseline (estimated marginal mean difference: -2.52 and -2.22, respectively; all P = .01), whereas no significant changes were observed in the GWHE group. For pain characteristics, the GWHE group had a worsening of pain at endpoint compared to baseline (estimated marginal mean difference: +2.83; P = .01), while no change was observed in the CIH group. Conclusion: Findings suggest a possible beneficial effect of combining 2 CIH therapies, mindfulness meditation and auricular acupuncture, in reducing overall symptom severity and individual symptom domains of fatigue, musculoskeletal, and mood/cognition in Veterans with GWI. Trial Registration: Clinical Trials identifier NCT02180243.

RESUMO

Purpose: The relationship between sleep and adiposity in older women remains unclear partly due to the reliance of body mass index as a measure of adiposity. The purpose of this study was to investigate associations between objectively measured sleep characteristics and body composition measured by dual energy x-ray absorptiometry (DXA) in older women. A secondary purpose was to examine if physical function mediates this relationship. Methods: Non-obese older women (ages 60-75 years, n=102) were included in the study. Total sleep time (TST), time in bed (TIB), sleep efficiency (SE), and wake after sleep onset (WASO) were determined by actigraphy. A battery of tests was used to assess physical function. Results: With adjustment for age, there was a negative association between TST and TIB with lean mass. Both grip strength and dominant leg extension were associated with TST, TIB, and lean mass; the associations between TST and TIB with lean mass were lost after adjusting for grip strength or leg extension strength. Additionally, SE was negatively associated with total, gynoid, and trunk lean mass, and there was a positive association between TST and percent trunk fat, and WASO and gynoid lean mass, with age adjusted. Conclusions: Sleep characteristics, TST, TIB, SE, and WASO, were associated body composition measures in this sample of older women. The relationship between TST and TIB with body composition was mediated, in part, by grip strength and leg extension strength.

RESUMO

INTRODUCTION: To evaluate the associations between neurocognitive and psychiatric health outcomes with mefloquine or any antimalarial exposure. MATERIALS AND METHODS: Medical records were systematically reviewed to identify veterans that indicated antimalarial medication use. Linear regression was performed to examine associations between mefloquine/antimalarial exposure and health outcomes. The mefloquine-exposed group was further compared with normative populations for the same health outcomes. RESULTS: In the adjusted models, no significant differences were noted between the two exposure groups and the unexposed group for any of the health measures (P-value > 0.05). When compared to normative population samples, the mefloquine-exposed group had poorer health and greater neurobehavioral symptom severity or cognitive complaints. CONCLUSION: This study suggests that mefloquine use by veterans referred for intensive evaluation of their military deployment exposures and health was not associated with increased, long-term, neurocognitive/psychiatric symptoms compared to unexposed veterans.

RESUMO

Traumatic brain injury (TBI) is known to be associated with poor sleep. In this report, we aimed to identify associations between differences in cortical volume and sleep quality post-TBI. MRI anatomical scans from 88 cases with TBI were analyzed in this report. Subjective sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Voxel Based Morphometry (VBM), was used to obtain statistical maps of the association between PSQI and cortical volume in gray matter and white matter voxels. Higher PSQI total scores (poor sleep quality) were strongly associated with smaller gray matter volume in the cerebellum. White matter volume was not associated with total PSQI. The sleep disturbance subcomponent showed a significant association with gray and white matter volumes in the cerebellum. Although not significant, cortical areas such as the cingulate and medial frontal regions were associated with sleep quality. The cerebellum with higher contribution to motor and autonomic systems was associated strongly with poor sleep quality. Additionally, regions that play critical roles in inhibitory brain function and suppress mind wandering (i.e., default mode network including medial frontal and cingulate regions) were associated (although to a lesser extent) with sleep. Our findings suggest that poor sleep quality following TBI is significantly associated with lower cerebellar volume, with trending relationships in regions associated with inhibitory function.

RESUMO

INTRODUCTION: Traumatic brain injury (TBI) or concussion is a known risk factor for multiple adverse health outcomes, including disturbed sleep. Although prior studies show adverse effects of TBI on sleep quality, its compounding effect with other factors on sleep is unknown. This meta-analysis aimed to quantify the effects of TBI on subjective sleep quality in the context of military status and other demographic factors. MATERIALS AND METHODS: A programmatic search of PubMed database from inception to June 2020 was conducted to identify studies that compared subjective sleep quality measured using Pittsburgh Sleep Quality Index (PSQI) in individuals with TBI relative to a control group. The meta-analysis included group-wise standard mean difference (SMD) and 95% CI. Pooled means and SDs were obtained for TBI and non-TBI groups with and without military service, and meta-regression was conducted to test for group effects. Exploratory analysis was performed to test for the effect of TBI, non-head injury, military status, sex, and age on sleep quality across studies. RESULTS: Twenty-six articles were included, resulting in a combined total of 5,366 individuals (2,387 TBI and 2,979 controls). Overall, individuals with TBI self-reported poorer sleep quality compared to controls (SMD = 0.63, 95% CI: 0.45 to 0.80). Subgroup analysis revealed differences in the overall effect of TBI on PSQI, with a large effect observed in the civilian subgroup (SMD: 0.80, 95% CI: 0.57 to 1.03) and a medium effect in the civilian subgroup with orthopedic injuries (SMD: 0.40, 95% CI: 0.13 to 0.65) and military/veteran subgroup (SMD: 0.43, 95% CI: 0.14 to 0.71). Exploratory analysis revealed that age and history of military service significantly impacted global PSQI scores. CONCLUSIONS: Poor sleep quality in TBI cohorts may be due to the influence of multiple factors. Military/veteran samples had poorer sleep quality compared to civilians even in the absence of TBI, possibly reflecting unique stressors associated with prior military experiences and the sequelae of these stressors or other physical and/or psychological traumas that combine to heightened vulnerability. These findings suggest that military service members and veterans with TBI are particularly at a higher risk of poor sleep and its associated adverse health outcomes. Additional research is needed to identify potential exposures that may further heighten vulnerability toward poorer sleep quality in those with TBI across both civilian and military/veteran populations.

RESUMO

Local-level childhood overweight and obesity data are often used to implement and evaluate community programs, as well as allocate resources to combat overweight and obesity. The most current substate estimates of US childhood obesity use data collected in 2007. Using a spatial multilevel model and the 2016 National Survey of Children's Health, we estimated childhood overweight and obesity prevalence rates at the Census regional division, state, and county levels using small-area estimation with poststratification. A sample of 24,162 children aged 10-17 years was used to estimate a national overweight and obesity rate of 30.7% (95% confidence interval: 27.0%, 34.9%). There was substantial county-to-county variability (range, 7.0% to 80.9%), with 31 out of 3,143 counties having an overweight and obesity rate significantly different from the national rate. Estimates from counties located in the Pacific region had higher uncertainty than other regions, driven by a higher proportion of underrepresented sociodemographic groups. Child-level overweight and obesity was related to race/ethnicity, sex, parental highest education (P < 0.01 for all), county-level walkability (P = 0.03), and urban/rural designation (P = 0.02). Overweight and obesity remains a vital issue for US youth, with substantial area-level variability. The additional uncertainty for underrepresented groups shows surveys need to better target diverse samples.

RESUMO

Local environments are increasingly the focus of health behavior research and practice to reduce gaps between fruit/vegetable intake, physical activity (PA), and related guidelines. This study examined the congruency between youth food and PA environments and differences by region, rurality, and income across the United States. Food and PA environment data were obtained for all U.S. counties (N = 3142) using publicly available, secondary sources. Relationships between the food and PA environment tertiles was represented using five categories: 1) congruent-low (county falls in both the low food and PA tertiles), 2) congruent-high (county falls in both the high food and PA tertiles), 3) incongruent-food high/PA low (county falls in high food and low PA tertiles), 4) incongruent-food low/PA high (county falls in low food and high PA tertiles), and 5) intermediate food or PA (county falls in the intermediate tertile for food and/or PA). Results showed disparities in food and PA environment congruency according to region, rurality, and income (p < .0001 for each). Nearly 25% of counties had incongruent food and PA environments, with food high/PA low counties mostly in rural and low-income areas, and food low/PA high counties mostly in metropolitan and high-income areas. Approximately 8.7% of counties were considered congruent-high and were mostly located in the Northeast, metropolitan, and high-income areas. Congruent-low counties made up 10.0% of counties and were mostly in the South, rural, and low-income areas. National and regional disparities in environmental obesity determinants were identified that can inform targeted public health interventions.

RESUMO

This study examined spatial patterns of obesogenic environments for US counties. We mapped the geographic dispersion of food and physical activity (PA) environments, assessed spatial clustering, and identified food and PA environment differences across U.S. regions and rurality categories. Substantial low food score clusters were located in the South and high score clusters in the Midwest and West. Low PA score clusters were located in the South and high score clusters in the Northeast and Midwest (p < .0001). For region, the South had significantly lower food and PA environment scores. For rurality, rural counties had significantly higher food environment scores and metropolitan counties had significantly higher PA environment scores (p < .0001). This study highlights geographic clustering and disparities in food and PA access nationwide. State and region-wide environmental inequalities may be targeted using structural interventions and policy initiatives to improve food and PA access.

RESUMO

BACKGROUND: Diverse environmental factors are associated with physical activity (PA) and healthy eating (HE) among youth. However, no study has created a comprehensive obesogenic environment index for children that can be applied at a large geographic scale. The purpose of this study was to describe the development of a childhood obesogenic environment index (COEI) at the county level across the United States. METHODS: A comprehensive search of review articles (n = 20) and input from experts (n = 12) were used to identify community-level variables associated with youth PA, HE, or overweight/obesity for potential inclusion in the index. Based on strength of associations in the literature, expert ratings, expertise of team members, and data source availability, 10 key variables were identified - six related to HE (# per 1000 residents for grocery/superstores, farmers markets, fast food restaurants, full-service restaurants, and convenience stores; as well as percentage of births at baby (breastfeeding)-friendly facilities) and four related to PA (percentage of population living close to exercise opportunities, percentage of population < 1 mile from a school, a composite walkability index, and number of violent crimes per 1000 residents). Data for each variable for all counties in the U.S. (n = 3142) were collected from publicly available sources. For each variable, all counties were ranked and assigned percentiles ranging from 0 to 100. Positive environmental variables (e.g., grocery stores, exercise opportunities) were reverse scored such that higher values for all variables indicated a more obesogenic environment. Finally, for each county, a total obesogenic environment index score was generated by calculating the average percentile for all 10 variables. RESULTS: The average COEI percentile ranged from 24.5-81.0 (M = 50.02,s.d. = 9.01) across US counties and was depicted spatially on a choropleth map. Obesogenic counties were more prevalent (F = 130.43,p < .0001) in the South region of the U.S. (M = 53.0,s.d. = 8.3) compared to the Northeast (M = 43.2,s.d. = 6.9), Midwest (M = 48.1,s.d. = 8.5), and West (M = 48.4,s.d. = 9.8). When examined by rurality, there were also significant differences (F = 175.86,p < .0001) between metropolitan (M = 46.5,s.d. = 8.4), micropolitan (M = 50.3,s.d. = 8.1), and rural counties (M = 52.9,s.d. = 8.8) across the U.S. CONCLUSION: The COEI can be applied to benchmark obesogenic environments and identify geographic disparities and intervention targets. Future research can examine associations with obesity and other health outcomes.

RESUMO

Older adults have low rates meeting the physical activity (PA) guidelines and high sedentary time. Low PA and excessive sedentary time have been linked to adverse health outcomes. Less is known about whether exercise training influences sedentary time and PA in various intensities. PURPOSE: This study aimed to examine the effects of a 16-wk aerobic exercise training on time spent being sedentary and on light-intensity PA (LPA) and moderate- to vigorous-intensity PA (MVPA) and step numbers in older women. METHODS: Inactive women (n = 61; age = 65.5 ± 4.3 yr) participated in moderate-intensity walking of either a low or a moderate dose (33.6 and 58.8 kJ·kg body weight per week, respectively). They wore a SenseWear Mini Armband at baseline and at end intervention to determine sedentary, LPA, and MVPA time and step numbers. RESULTS: Time being sedentary, or spent on LPA and MVPA, did not change differently by exercise groups with different doses (all P values for group-time interaction >0.580). Overall, time being sedentary reduced from baseline to end intervention by approximately 39 min·d (P < 0.001), and LPA increased by 19 min·d (P = 0.003). MVPA time increased (P < 0.001), which was primarily accounted for by the supervised exercise. Interestingly, daily steps increased more in the moderate-dose than the low-dose group (P = 0.023 for group-time interaction; 33.6% and 19.8% median increase in moderate- and low-dose groups, respectively). Also, there were individual differences in these changes. CONCLUSION: Results indicated that, on average, older women did not reduce time of LPA or MVPA outside the exercise program or increase sedentary time as a result of participating in the exercise program.

RESUMO

BACKGROUND: Physician practice organization is shifting away from solo, independent practices toward direct employment, but trends for rural-urban differences are often analyzed by dichotomizing rurality. The purpose of this analysis was to examine trends in practice organization across 3 levels of rurality over a 21-year period in South Carolina. METHODS: Physician license renewal forms were used to ascertain type of practice organization where physicians worked in South Carolina between 1995 and 2015. Physicians were divided into 4 categories: physicians in independent solo practices, physicians in independent group practices, employed physicians, and other. Historical trends in type of practice organization were evaluated for each level of rurality (metropolitan, micropolitan, and small adjacent/remote rural) using the National Cancer Institute's Joinpoint regression models. RESULTS: There was a continual increase in physician renewals indicating employment, with an average annual increase of 5.9%. Micropolitan rural counties demonstrated the greatest average increase in license renewals for employed physicians (average annual increase = 7.4%; P < .05). The ratio of license renewals per 100,000 population for physicians in independent solo practices declined significantly over time. Micropolitan and small adjacent/remote rural counties saw an increase in the annual decline for this type of practice organization in 2007. CONCLUSIONS: A shift toward physician employment was observed at all levels of rurality. Rural counties exhibited a more pronounced transition between the types of practice organization compared to metropolitan counties. Research is needed to address the implications of these changes for rural providers and patients.

RESUMO

Objective/Background: Exercise training has been demonstrated to beneficially influence mean-level measures of sleep; however, few studies have examined the impact of an exercise intervention on night-to-night variability in sleep. This study investigated whether four months of moderate-intensity exercise impacted night-to-night variability in sleep among older women. Methods: Participants (n = 49) were randomized to one of two moderate-intensity walking programs with different doses of energy expenditure: low-dose (n = 23: 8 kcal/kg of body weight per week) or high-dose (n = 26: 14 kcal/kg of body weight per week). Sleep parameters were assessed objectively via actigraphy at baseline, mid- (2 months), and postintervention (4 months). Nightly variability in each of the sleep parameters was calculated using the seven-day standard deviation (SD) and a coefficient of variation (SD/mean x 100%). Cardiorespiratory fitness (VO2peak) was measured at baseline and postintervention using a graded treadmill test. Results: Both measures of nightly variability demonstrated a borderline to significantly lower amount of night-to-night variability in wake time after sleep onset (WASO) and number of awakenings at postintervention in comparison to baseline (p ≤ 0.05). Higher VO2peak levels at baseline were associated with less time in bed and lower total sleep time variability throughout the exercise intervention (p < 0.05). Conclusion: Overall, participation in moderate-intensity exercise was observed to reduce the amount of nightly variability for WASO and number of awakenings over time in older women.

RESUMO

In addition to individual-level characteristics, characteristics of the social and physical environments in which individuals reside may adversely impact health outcomes. Careful attention to the role of "place" can result in programs that successfully deliver services to those most at risk. This retrospective, cross-sectional study used geocoded residential addresses from 3090 households enrolled in a South Carolina (SC) home visiting program, 2013-2016, and corresponding years of data for maternal and child health outcomes obtained from vital records data. ZIP Code Tabulation Areas (ZCTAs) served as the primary geographic unit of analysis. ZCTAS with high volumes of birth or adverse maternal and child health outcomes for any of 10 indicators were flagged. Distribution of enrolled households across highest-risk ZCTAs was calculated. Of 379 ZCTAS with reported data, 152 had 8 or more risk flags. Of the 152 highest-risk ZCTAs, 33 also had high birth volumes. Fifty-seven of the 152 highest-risk ZCTAs had no enrollees; seven of the 33 highest-risk/highest-volume ZCTAS had no enrollees. Service delivery gaps existed despite a statewide, county-level needs assessment conducted prior to program implementation. This study suggests methods to identify service areas of need, as an ongoing effort toward program improvement.

RESUMO

This study investigated the acute effect of exercise on sleep outcomes among healthy older women by comparing days with structured exercise versus days without structured exercise during 4 months of exercise training. Participants (n = 51) in this study had wrist-worn actigraphic sleep data available following at least 3 days with structured exercise and 3 days without structured exercise at mid-intervention and at the end of intervention. The exercise intervention was treadmill walking. Multilevel models were used to examine whether structured exercise impacted sleep outcomes during the corresponding night. Overall, 1,362 nights of data were included in the analyses. In unadjusted and adjusted models, bedtimes were significantly earlier on evenings following an acute bout of structured exercise than on evenings without structured exercise. No other sleep parameters differed between exercise and nonexercise days. Understanding the effects of exercise on sleep in this understudied population may help to improve their overall sleep quality.

RESUMO

Objectives Studies suggest that parents tend to misperceive their child's actual weight status and typically underestimate their child's weight. Since few studies examine the factors that influence parental misperception, this study aims to assess the influence of parent and child factors with parental misperception of their child's actual weight status who were either at their recommended weight or overweight/obese in South Carolina in 2013 and 2014. Methods Secondary data were obtained from the Behavioral Risk Factor Surveillance System (BRFSS) and the Children's Health Assessment Survey (CHAS) in 2013 and 2014 in SC. Parental misperception of child's actual weight status was measured by comparing parental perception to their child's actual weightstatus measured via BMI. Logistic regression was conducted to assess the association between parental and child factors with parental misperception of child's weight status. Results In the adjusted multivariate analysis, only child's age was significantly and positively associated with parental misperception of their child's actual weight status. Conclusions for Practice This cross sectional analysis showed an association between child's age and parental misperception of child's actual weight status. It is essential to educate parents about their children's weight status, especially among young children.

RESUMO

Previous studies have shown inconsistent findings regarding how structured exercise affects energy expenditure (EE). This study was designed to determine the changes in EE and physical activity following exercise training in older women. Nonobese (body mass index = 25.8 ± 3.4 kg·m-2) women (60-75 years, n = 72) completed a 4-month supervised aerobic exercise training of lower- or higher-dose (33.6 and 58.8 kJ·kg-1 body weight weekly, respectively) at 50-55% of heart rate reserve. Total daily EE (TDEE) by the doubly labeled water method, resting metabolic rate (RMR) via indirect calorimetry, and physical activity by accelerometer were determined before and at the end of exercise training. Nonexercise activity thermogenesis (NEAT) was calculated. Following exercise training, the changes in components of TDEE and total physical activity did not differ by group. In the entire sample, TDEE, RMR, NEAT and total physical activity did not change (P > 0.05 for all). However, a significant baseline physical activity × time interaction was found for several of the variables. Data were therefore stratified into tertiles of baseline physical activity. In the high tertile, TDEE remained unchanged, but total physical activity decreased (P = 0.012). In contrast, in the middle and low tertiles, NEAT remained unchanged, and total physical activity increased (P < 0.05 for both). In conclusion, aerobic exercise training did not change TDEE, RMR, NEAT, or total physical activity in this sample of older women. Exercise dose did not, but baseline physical activity levels might, influence EE responses and total physical activity changes.

RESUMO

BACKGROUND: Low cardiorespiratory fitness has been established as a risk factor for cardiovascular-related morbidity. However, research about the impact of fitness on lipid abnormalities, including atherogenic dyslipidemia, has produced mixed results. The purpose of this investigation is to examine the influence of baseline fitness and changes in fitness on the development of atherogenic dyslipidemia. METHODS: All participants completed at least 3 comprehensive medical examinations performed by a physician that included a maximal treadmill test between 1976 and 2006 at the Cooper Clinic in Dallas, Texas. Atherogenic dyslipidemia was defined as a triad of lipid abnormalities: low high-density-lipoprotein cholesterol ([HDL-C] <40 mg/dL), high triglycerides ([TGs] ≥200 mg/dL), and high low-density-lipoprotein cholesterol ([LDL-C] ≥160 mg/dL). RESULTS: A total of 193 participants developed atherogenic dyslipidemia during an average of 8.85 years of follow-up. High baseline fitness was protective against the development of atherogenic dyslipidemia in comparison with those with low fitness (odds ratio [OR] 0.57; 95% confidence interval [CI], 0.37-0.89); however, this relationship became nonsignificant after controlling for baseline HDL-C, LDL-C, and TG levels. Participants who maintained fitness over time had lower odds of developing atherogenic dyslipidemia than those with a reduction in fitness (OR 0.56; 95% CI, 0.34-0.91) after adjusting for baseline confounders and changes in known risk factors. CONCLUSIONS: High fitness at baseline and maintenance of fitness over time are protective against the development of atherogenic dyslipidemia.

RESUMO

OBJECTIVE: To assess and enumerate the trends in diabetes prevalence, morbidity and mortality rates in South Carolina (SC) within the past 2 decades. MATERIALS AND METHODS: We analyzed state-level data from vital records, Behavioral Risk Factor Surveillance System, Children's Health Assessment Survey and Administrative Claim Files. RESULTS: Over the past 20 years, there has been an average 2.5% annual increase in diabetes prevalence among adults in SC (P < 0.01). Although a typical reduction in mortality rate of 2.2% has been observed during the same period, the increased number of people living with diabetes (from 5.0% in 1995 to 12.0% in 2014) has brought more need for diabetes care, particularly for severe in-hospital cases and cases with crisis at the emergency department, totaling $404 million in annual costs. CONCLUSIONS: SC has experienced an epidemic of diabetes. Coupled with declining trends in mortality and increased hospitalization and emergency department visits, the state is experiencing historical morbidity and complications due to diabetes. The shift in complexity of the disease onset and management has resulted in more individuals living with cardiovascular disease and other comorbidities. The cost of care for all South Carolinians with diabetes is estimated to exceed 2.8 billion dollars in 2014 and projected to be more than 4 billion dollars by 2020. If the diabetes prevalence trend of increasing rates continues over the next 20 years, the number of individuals living with diabetes and its complications would rise to 1.3 million in SC.

RESUMO

The purpose of this project was to determine the effectiveness of the Helping Administer to the Needs of the Student with Diabetes in Schools (H.A.N.D.S.(sm)) continuing education program in improving the level of experience and competence in performing services associated with diabetes care. This program is a live course for school nurses providing clinical information about diabetes management and their professional role in the care of students with diabetes. Pre- and post-surveys were administered via e-mail to assess their level of experience and competence in diabetes care. A total of 105 nurses completed both surveys and were included in the analysis. The changes between pre- and post-survey questions were assessed. The H.A.N.D.S. participants' levels of experience and competence for each of the four categories of diabetes care improved significantly, and a greater number of nurses reported being able to perform the services independently and having the ability to teach others.
