RESUMO
OBJECTIVES: Elder mistreatment (EM), encompassing abuse and neglect, is a significant public health issue, affecting up to 10% of community-dwelling older adults annually. Elder mistreatment is a growing concern with a higher prevalence in institutional settings and substantial associated healthcare costs. Prehospital clinicians (PHCs) such as emergency medical technicians and paramedics are uniquely positioned to detect and report EM during their interactions with older adults in their homes. The objective of the study is to describe the rate and characteristics of EM documented by PHCs using the National Emergency Medical Services Information System (NEMSIS) database. METHODS: This study analyzed data from NEMSIS, which includes standardized information about PHC emergency response encounters across the United States. In 2018, 22,532,890 activations were included from 9,599 agencies in 43 states and US territories. Elder mistreatment was identified using specific International Classification of Diseases (ICD) codes related to EM. Demographic data, injury location, and associated physical findings were also examined. RESULTS: Out of 9,605,522 EMS encounters for patients aged ≥60, EM was coded in 1,765 encounters (0.02%). Most EM cases were listed as the cause of injury (64%), followed by the clinician's first impression (25.4%). Physical abuse was the most common type of mistreatment reported (20.8%), followed by sexual abuse (18.2%), neglect (9.7%), and psychological/emotional abuse (0.34%). The median age of patients with documented EM was 72, and 62.3% were female. The most common anatomic locations of injuries were the lower extremities, head, and upper extremities. CONCLUSIONS: Despite the high prevalence of EM, PHCs infrequently document EM in their encounters with older adults. Additional training and comprehensive protocols are needed to improve the identification and reporting of EM, mainly elder neglect. Empowering PHCs through education and protocol development can significantly impact the detection and intervention of EM.
RESUMO
Developing reliable screening tools to identify elder mistreatment requires an accurate and reproducible reference standard. This study sought to investigate the reliability of the Longitudinal, Experts, All Data (LEAD) methodology as a reference standard in confirming presence of elder mistreatment. We analyzed data from a large, emergency department-based study that used a LEAD panel to determine the reference standard. For this study, a second, blinded LEAD panel reviewed clinical material for 40 patients. For each panel, five content experts voted on whether elder mistreatment was present. We found moderate agreement between the two LEAD panels in determining presence of elder mistreatment: 85% agreement; k = 0.58; 95% Confidence Interval 0.28-0.87. Individual raters for both LEAD panels reported being mostly certain or certain >90% of votes. Efforts to further characterize and improve the reliability of the LEAD methodology in this context are warranted.

Older adults have physical and social barriers to eating but whether this affects functional status is unknown. We examined associations between eating barriers and physical function in the Women's Health Initiative (WHI). In 2012-14, a subset of alive and participating women (n = 5910) completed an in-home examination including the Short Physical Performance Battery (SPPB) (grip strength, balance, timed walking speed, chair stand). WHI participants complete annual mailed questionnaires; the 2013-14 questionnaire included items on eating alone, eating < two meals/day, dentition problems affecting eating, physical difficulties with cooking/shopping and monetary resources for food. Linear regression tested associations of these eating barriers with SPPB, adjusting for BMI, age, race/ethnicity, and medical multimorbidities. Over half (56.8%) of participants were ≥ 75 years, 98.8% had a BMI ≥ 25.0 kg/m2 and 66% had multimorbidities. Eating barriers, excluding eating alone, were associated with significantly lower total (all p < .001) and component-specific, multivariate-adjusted SPPB scores (all p < .05). Compared to no barriers, eating < two meals/day (7.83 vs. 8.38, p < .0002), dentition problems (7.69 vs. 8.38, p < .0001), inability to shop/prepare meals (7.74 vs. 8.38, p < .0001) and insufficient resources (7.84 vs. 8.37 p < .001) were significantly associated with multivariate-adjusted mean SPPB score < 8. Models additionally adjusting for Healthy Eating Index-2010 had little influence on scores. As barriers increased, scores declined further for grip strength (16.10 kg for 4-5 barriers, p = .001), timed walk (0.58 m/s for 4-5 barriers, p = .001) and total SPPB (7.27 for 4-5 barriers, p < .0001). In conclusion, in this WHI subset, eating barriers were associated with poor SPPB scores.

OBJECTIVE: To pilot test the feasibility of implementing an elder abuse (EA) screening tool (DETECT) designed for medics. METHODS: Testing occurred between September 17th, 2015 and October 26th, 2015. MedStar Mobile Healthcare medics completed the DETECT tool when responding to calls for community-dwelling patients 65 years of age or older. RESULTS: The DETECT tool was used 1,248 times by 97% of medics responding to an eligible 911 call. Medics responded affirmatively to at least one screening item on 209 of the completed screenings (16.8%). Immediately following the introduction of the DETECT tool, there was an increase of 5.4 (226% above baseline) reports per month (p = 0.0056). CONCLUSIONS: The DETECT tool was easily incorporated into medic's field-based practice and resulted in an increase in medic generated reports of EA to APS. Future research designed to evaluate the tool's validity and reliability are warranted.

Objective: to examine the association of parental longevity with healthy survival to age 90 years. Methods: this was a prospective study among a racially and ethnically diverse cohort of 22,735 postmenopausal women from the Women's Health Initiative recruited from 1993 to 1998 and followed through 2017. Women reported maternal and paternal ages at death and current age of alive parents. Parental survival categories were <70, 70-79 (reference), 80-89 and ≥90 years (longevity). Healthy ageing was defined as reaching age 90 without major chronic conditions (coronary heart disease, stroke, diabetes, cancer, or hip fracture) or physical limitations. Results: women whose mothers survived to ≥90 years were more likely to attain healthy ageing (OR, 1.25; 95% CI, 1.11-1.42) and less likely to die before age 90 (OR, 0.75; 95% CI, 0.68-0.83). Women whose fathers survived to ≥90 years did not have significantly increased odds of healthy ageing but showed 21% (OR, 0.79; 95% CI, 0.70-0.90) decreased odds of death before age 90. Women whose mother and father both lived to 90 had the strongest odds of healthy ageing (OR, 1.38; 95% CI, 1.09-1.75) and decreased odds of death (OR, 0.68; 95% CI, 0.54-0.85). The proportion of healthy survivors was highest among women whose mother and father lived to 90 (28.6%), followed by those whose mother only lived to 90 (23.2%). Conclusions: parental longevity predicted healthy ageing in a national cohort of postmenopausal women, supporting the view that genetic, environmental, and behavioral factors transmitted across generations may influence ageing outcomes among offspring.

BACKGROUND: Despite concerns over measurement error, self-report continues to be the most common measure of adolescent alcohol use used by researchers. Objective measures of adolescent alcohol use continue to advance; however, they tend to be cost prohibitive for larger studies. By combining appropriate statistical techniques and validation subsamples, the benefits of objective alcohol measures can be made more accessible to a greater number of researchers. OBJECTIVES: To compare three easily implemented methods to correct for measurement error when objective measures of alcohol use are available for a subsample of participants, regression calibration, multiple imputation for measurement error (MIME), and probabilistic sensitivity analysis (PSA), and provide guidance regarding the use of each method in scenarios likely to occur in practice. METHODS: This simulation experiment compared the performance of each method across different sample sizes, both differential and non-differential error, and differing levels of sensitivity and specificity of the exposure measure. RESULTS: Failure to adjust for measurement error led to substantial bias across all simulated scenarios ranging from a 35% to 208% change in the log-odds. For non-differential misclassification, regression calibration reduced this bias to between a 1% and 23% change in the log-odds regardless of sample size. At higher sample sizes, MIME produced approximately unbiased (between a 0% and 9% change in the log-odds) and relatively efficient corrections for both non-differential and differential misclassification. PSA provided little utility for correcting misclassification due to the inefficiency of its estimates. CONCLUSION: Concern over measurement error resulting from self-reported adolescent alcohol use persists in research. Where appropriate, methods involving validity subsamples provide an efficient avenue for addressing these concerns.

BACKGROUND: Scant research has examined event-level risk factors for impaired driving in natural drinking settings. This study assessed driving self-efficacy among intoxicated individuals to better understand decision-making about alcohol-impaired driving at night after exiting on-premise drinking establishments. METHODS: Interview and breath test data were collected from bar patrons (n = 512) exiting 2 college bar districts in Florida and Texas. RESULTS: Results from a multivariable linear regression model indicated that self-efficacy to drive while intoxicated was more strongly associated with situational variables, that is, perceived drunkenness and self-estimated blood alcohol concentration than patron traits, that is, past-year history of drinking, risk proneness, and sex. A large proportion of bar patrons, particularly men, expressed confidence in their ability to drive, despite being highly intoxicated. Moreover, the majority of legally intoxicated patrons who were confident in their ability to drive were aware of their high level of intoxication. CONCLUSIONS: Emphasis should be placed on the enactment and enforcement of policies and laws to prevent alcohol-impaired driving.

Importance: Social isolation and loneliness are increasing public health concerns and have been associated with increased risk of cardiovascular disease (CVD) among older adults. Objective: To examine the associations of social isolation and loneliness with incident CVD in a large cohort of postmenopausal women and whether social support moderated these associations. Design, Setting, and Participants: This prospective cohort study, conducted from March 2011 through March 2019, included community-living US women aged 65 to 99 years from the Women's Health Initiative Extension Study II who had no history of myocardial infarction, stroke, or coronary heart disease. Exposures: Social isolation and loneliness were ascertained using validated questionnaires. Main Outcomes and Measures: The main outcome was major CVD, which was physician adjudicated using medical records and included coronary heart disease, stroke, and death from CVD. Continuous scores of social isolation and loneliness were analyzed. Hazard ratios (HRs) and 95% CIs for CVD were calculated for women with high social isolation and loneliness scores (midpoint of the upper half of the distribution) vs those with low scores (midpoint of the lower half of the distribution) using multivariable Cox proportional hazards regression models adjusting for age, race and ethnicity, educational level, and depression and then adding relevant health behavior and health status variables. Questionnaire-assessed social support was tested as a potential effect modifier. Results: Among 57â¯825 women (mean [SD] age, 79.0 [6.1] years; 89.1% White), 1599 major CVD events occurred over 186â¯762 person-years. The HR for the association of high vs low social isolation scores with CVD was 1.18 (95% CI, 1.13-1.23), and the HR for the association of high vs low loneliness scores with CVD was 1.14 (95% CI, 1.10-1.18). The HRs after additional adjustment for health behaviors and health status were 1.08 (95% CI, 1.03-1.12; 8.0% higher risk) for social isolation and 1.05 (95% CI, 1.01-1.09; 5.0% higher risk) for loneliness. Women with both high social isolation and high loneliness scores had a 13.0% to 27.0% higher risk of incident CVD than did women with low social isolation and low loneliness scores. Social support was not a significant effect modifier of the associations (social isolation × social support: r, -0.18; P = .86; loneliness × social support: r, 0.78; P = .48). Conclusions and Relevance: In this cohort study, social isolation and loneliness were independently associated with modestly higher risk of CVD among postmenopausal women in the US, and women with both social isolation and loneliness had greater CVD risk than did those with either exposure alone. The findings suggest that these prevalent psychosocial processes merit increased attention for prevention of CVD in older women, particularly in the era of COVID-19.

BACKGROUND: Exposure to ultraviolet radiation (UVR) is the major modifiable risk factor for skin cancers. The majority of lifetime UVR exposure occurs before age 20, underscoring an important window for risk reduction. Incorporation of skills-based sunscreen education into school health curricula may foster the development of consistent and effective use of sunscreen among children and youth. We describe the study protocol for a first-of-its-kind study that examined the feasibility of bringing skills-based sunscreen education into kindergarten classrooms. METHODS: Participants were 96 kindergarten students across four classrooms in a single elementary school. A single-blind open-label trial design was used to evaluate the feasibility of incorporating a song-based, video-guided intervention for independent application of sunscreen into the kindergarten curriculum. Students first completed a 10-day no-intervention baseline period, followed by a 10-day intervention period, and then a 10-day randomized follow-up period where students were randomly assigned to continue with the intervention or to revert to the no-intervention condition. OUTCOMES: Feasibility metrics associated with study process, resources, management, scientific outcomes and safety were gathered. The primary outcome was pre-to-post intervention changes in student engagement in the sunscreen task. The secondary outcome was pre-to-post intervention changes in the proportion of exposed skin to which a student applies sunscreen. Teacher and student perceptions of intervention value and utility were also evaluated. DISCUSSION: This is the study protocol for a clinical trial designed to determine the feasibility of implementing a skills-based sunscreen curriculum in kindergarten classrooms. Next steps include evaluation of the intervention for efficacy and effectiveness. CLINICAL TRIAL REGISTRATION: NCT03752736.

INTRODUCTION: Elder mistreatment (EM) is a high prevalence threat to the health and well-being of older adults in the USA. Medics are well-positioned to help with identification of older adults at risk for EM, however, field robust screening tools appropriate for efficient, observation-based screening are lacking. Prior work by this team focused on the development and initial pilot testing of an observation-based EM screening tool named detection of elder abuse through emergency care technicians (DETECT), designed to be implemented by medics during the course of an emergency response (911) call. The objective of the present work is to validate and further refine this tool in preparation for clinical dissemination. METHODS AND ANALYSIS: Approximately 59 400 community-dwelling older adults who place 911 calls during the 36-month study observation period will be screened by medics responding to the call using the DETECT tool. Next, a random subsample of 2520 of the 59 400 older adults screened will be selected to participate in a follow-up interview approximately 2 weeks following the completion of the screening. Follow-up interviews will consist of a medic-led semistructured interview designed to assess the older adult's likelihood of abuse exposure, physical/mental health status, cognitive functioning, and to systematically evaluate the quality and condition of their physical and social living environment. The data from 25% (n=648) of these follow-up interviews will be presented to a longitudinal, experts and all data panel for a final determination of EM exposure status, representing the closest proxy to a 'gold standard' measure available. ETHICS AND DISSEMINATION: This study has been reviewed and approved by the Committee for the Protection of Human Subjects at the University of Texas School of Public Health. The results will be disseminated through formal presentations at local, national and international conferences and through publication in peer-reviewed scientific journals.

Importance: Elder mistreatment is underdetected and underreported. The more than 800â¯000 medics providing services in every county in the United States represent an important and underused surveillance system. Objective: To investigate the association between the Detection of Elder Mistreatment Through Emergency Care Technician (DETECT) screening tool use and the number of medic reports made to Adult Protective Services (APS) over a period of approximately 3 years. Design, Setting, and Participants: This quality improvement study used a difference in difference in differences design and included adults aged 65 years and older who were reported to Texas APS in the study region (246 cities in Denton, Johnson, and Tarrant Counties) between December 31, 2014, and February 28, 2018. Exposures: The DETECT screening tool. Main Outcomes and Measures: Reports to APS. Results: The mean (SD) age of the 11â¯178 older adults included in this study was 76 (8) years (range, 65-105 years); there was no reported data on patient sex. A total of 18â¯080 reports of elder mistreatment were recorded. Medics within the study region reported more cases of elder mistreatment during the implementation of the screening tool (relative risk [RR], 4.14; 95% CI, 3.25-5.27). After adjusting for changes in the number of elder mistreatment reports in the comparison groups (ie, underlying changes in reporting trends), the number of reports to APS increased (RR, 3.03; 95% CI, 2.06-4.46). The occurrence of elder mistreatment was validated in 83% (95% CI, 75%-91%) of the reports investigated by APS during the periods when medics did not have access to the screening tool compared with 82% (95% CI, 77%-87%) during the periods when medics had access to the screening tool, indicating that there were no differences in the proportion of reports that resulted in a validated APS investigation. Conclusions and Relevance: The findings suggest that incorporating the DETECT screening tool into the routine practices of medics is associated with substantial increases in the frequency with which clinicians report potential cases of elder mistreatment to APS.

BACKGROUND: Research on the physical and mental health profiles and patterns of health care use among women veterans receiving health care from the Department of Veterans Affairs (VA) on the island of Puerto Rico is lacking. METHODS: This cross-sectional study examines differences in physical and mental health conditions, and patterns of VA health care use, between women veterans of the Operation Iraqi Freedom/Operation Enduring Freedom (OIF/OEF) era who were using VA facilities in Puerto Rico (n = 897) and those using U.S.-based VA facilities (n = 117,216) from 2002 to 2015. RESULTS: Results of fully adjusted logistic regression models revealed that OIF/OEF women in Puerto Rico had heightened risk for global pain-related disorders (i.e., any pain) (adjusted odds ratio [AOR], 1.45; 95% confidence interval [CI], 1.22-1.71), back pain (AOR, 1.83; 95% CI, 1.56-2.14), diabetes (AOR, 1.42; 95% CI, 1.03-1.95), hyperlipidemia (AOR, 3.34; 95% CI, 2.80-3.98), major depression (AOR, 1.78; 95% CI, 1.53-2.06), and bipolar depression (AOR, 1.66; 95% CI, 1.34-2.04). They also evidenced greater risk for a host of reproductive health conditions and had higher average annual use of VA health care than their U.S. counterparts. CONCLUSIONS: OIF/OEF women receiving VA health care in Puerto Rico evidenced a greater burden of physical illness, depression, and heightened use of VA health care services relative to their U.S. counterparts. Providers' increased awareness of the physical and mental health care needs of this population is warranted. Research efforts that help to identify efficient and effective strategies to provide culturally tailored and/or personalized health care for this population could also be useful.

OBJECTIVE: To examine associations of parental ages at childbirth with healthy survival to age 90 years among older women. STUDY DESIGN: This study included a racially and ethnically diverse sub-cohort of 8,983 postmenopausal women from the larger Women's Health Initiative population, recruited during 1993-1998 and followed for up to 25 years through 2018. MAIN OUTCOME MEASURES: The outcome was categorized as: 1) healthy survival, defined as survival to age 90 without major morbidities (coronary heart disease, stroke, diabetes, cancer, or hip fracture) or mobility disability; 2) usual survival, defined as survival to age 90 without healthy aging (reference category); or 3) death before age 90. Women reported their own and their parents' birth years, and parental ages at childbirth were calculated and categorized as <25, 25-29, 30-34, or ≥35 years. RESULTS: Women were aged on average 71.3 (standard deviation 2.7; range 65-79) years at baseline. There was no significant association of maternal age at childbirth with healthy survival to age 90 or death before age 90. Women born to fathers aged ≥35 compared with 30-34 years at their births were more likely to achieve healthy than usual survival (OR, 1.15; 95% CI, 1.00-1.32). There was no association of paternal age at childbirth with death before age 90. CONCLUSIONS: Findings suggest that being born to older fathers was associated with healthy survival to age 90 among women who had survived to ages 65-79 years at study baseline. There was no association of maternal age at childbirth with healthy survival to age 90 among these older women.

OBJECTIVES: To examine whether trajectories of global cognitive function over time in studies that change assessment protocols may be modeled based on an individual's performance relative to others in the study cohort. DESIGN: Extended follow-up of a cohort originally enrolled in a clinical trial of postmenopausal hormone therapy. SETTING: The Women's Health Initiative Memory Study switched from an in-person interview with the Modified Mini-Mental State Examination to a telephone-based interview with the modified Telephone Interview for Cognitive Status to assess global cognitive function over long-term follow-up. PARTICIPANTS: Women aged 75 to 92 (N=2,561). MEASUREMENTS: Annual cognitive assessments from participants, ranked according to age-, race- and ethnicity-adjusted performance levels, were used to identify distinct trajectories. Participants assigned to the resulting trajectories were compared for selected risk factor profiles. RESULTS: Our approach grouped participants into five trajectories according to relative cognitive performance over time. These groups differed significantly according to 3 known risk factors for cognitive decline-education level, apolipoprotein E-ϵ4 genotype, and type 2 diabetes mellitus-and a biomarker based on brain structure that has been linked to cognitive decline and Alzheimer's disease. Participants with consistently low relative levels of cognitive function over time and those whose relative performance over time declined to these levels tended to have poorer risk factor profiles. CONCLUSION: Longitudinal measures of an individual's relative performance on different assessment protocols for global cognitive function can be used to identify trajectories of change over time that appear to have internal validity with respect to known risk factors.

OBJECTIVES: To examine prospective associations between changes in physical activity (PA) and changes in physical performance measures (PPMs) over 6 years in older women. DESIGN: Prospective cohort study. SETTING: Forty clinical centers in the United States. PARTICIPANTS: Women aged 65 and older (mean age 69.8) enrolled in the Women's Health Initiative Clinical Trials with gait speed, timed chair stand, grip strength, and self-reported recreational PA data assessed at baseline (1993-98) and follow-up Years 1, 3, and 6 (N = 5,092). MEASUREMENTS: Mixed-effects linear regression models were used to determine the association between time-varying PA and change in each PPM. Potential interactions between time-varying PA and age (<70, ≥70) were also tested. RESULTS: Significan, dose-response associations between PA and improvements in all PPMs were observed over the 6 years of follow-up after adjusting for important covariates. High PA groups (≥1,200 metabolic equivalent (MET)-min/wk) had stronger grip strength (0.48 kg greater; P < .01), more chair stands (0.35 more; P < .001), and faster gait speeds (0.06 m/s faster; P < .001) than sedentary women (<100 MET-min/wk). Higher PA levels were associated with a greater increase in chair stands over time in women aged 70 and older (P < .001) than in those younger than 70 (Pinteraction for age = .01). CONCLUSION: In postmenopausal women, maintaining high PA levels over time is associated with better lower extremity function. These data support the view that regular PA plays an important role in maintaining functional status during aging in older women.

AIMS: In recent years, studies have indicated that consumers of alcohol mixed with energy drink (AmED) are more likely to drink heavily and experience more negative consequences than consumers who avoid these beverages. Although researchers have identified a number of plausible hypotheses that explain how alcohol-energy drink co-ingestion could cause greater alcohol consumption, there has been no postulation about reverse causal relations. This paper identifies several plausible hypotheses for the observed associations between AmED consumption and greater alcohol consumption, and provides initial evidence for one such hypothesis suggesting that heavy drinking may be a determinant of AmED use. METHOD: Data collected from 511bar patrons were used to examine the plausibility of one of the proposed hypotheses, i.e., AmED is an artifact of heavy drinking. Associations between the consumption of an assortment of alcoholic beverage types and total alcohol consumption were examined at the event-level, to assess whether AmED is uniquely related with greater alcohol consumption. RESULTS: Increased alcohol consumption was associated with greater odds of consuming most alcoholic beverage types; this association was not unique to AmED. CONCLUSIONS: Results support the overlooked hypothesis that AmED use is an artifact of heavy drinking. Thus, AmED consumption may be a consequence or marker of heavier drinking. Much of the existing research on alcoholic beverage types is limited in its ability to implicate any specific type of drink, including AmED, as a cause of increased alcohol consumption and related harm. More rigorous study designs are needed to examine causal relationships.
