This article explores staff work patterns in an Australian residential aged care facility and the implications for high-quality care. Rarely available minute by minute, time and motion, and ethnographic data demonstrate that nurses and care staff engage in high degrees of multitasking and mental switching between residents. Mental switching occurs up to 18 times per hour (every 3 min); multitasking occurs on average for 37 min/h. Labor process theory is used to examine these outcomes and to explore the concepts of high demand and high commitment as core components of work intensification. These conditions of work result in high levels of cognitive burden and stress on staff in managing the multitasking and mental switching, exacerbated by lack of knowledge about residents associated with labor force casualization. These new interpretations of data in relation to mental and manual labor can contribute to understanding, and, therefore, problem solving, in the aged care sector., (© 2022 The Authors.

Introduction: Internationally, the adoption of technology into residential aged care settings has been slow and fraught with multiple challenges for residents, staff and service providers. The aim of this study was to evaluate the acceptability, efficiency, and quality of health information system implementation into aged care., Methods: Three-stage, mixed-methods participatory action research, concurrent with the natural experiment of a co-designed health information system implementation into a 169-bed aged care home in Australia. Data were collected pre-, during, and post implementation between 2019 and 2021. Qualitative data included focus groups, interviews, and observations. Quantitative data included work observations, pedometers, record audits, incident reports and staff and resident surveys. There were 162 participants composed of 65 aged care residents, 90 staff, and 7 managers/consultants., Results: Improved work efficiency included reduced staff time searching for information (6%); reduced nurse time on documentation (20.4% to 6.4%), and 25% less steps. Documentation improvement included resident assessments (68% to 96%); resident-focused goals (56% to 88%) and evaluations (31% to 88%). The staff reported being better equipped to manage the 'delicacies of dignity'., Conclusion: Implementation of a health information system into a residential aged care facility was associated with improved resident-focused care and staff efficiency., Clinical Relevance: Technology can support nurses and care staff to spend more time with residents in residential aged care homes, improve the quality of resident care, and assist meeting regulatory reporting requirements. Flexible and tailored co-design strategies can enhance both effectiveness and success of technology implementation into residential aged care., (© 2022 The Authors.

Aims and Objectives: To evaluate acceptability, efficiency, and quality of a new digital care management system in a residential aged care home (RACH)., Background: Improving care quality and efficiency in RACH, while simultaneously upgrading data management, is a priority for communities and governments., Design: Participatory action research with mixed methods data collection was employed to evaluate a digital care management system implemented at a 169-bed RACH. This paper reports qualitative findings of the 2-year evaluation., Methods: Qualitative data were collected using focus groups with residents, visitors, nurses, managers, care workers, and consultants; resident/visitor and staff hallway interviews and responses to open-ended questions in online staff surveys. Data were analysed thematically under the four predetermined study objectives. Reporting adhered to COREQ guidelines., Results: 325 data captures from 88 participants, over seven data sources were coded. Findings indicate that the system was acceptable to both residents and staff due to perceptions of time-saving and improved quality of care. Increased efficiency was perceived through timeliness as well as reduced time spent retrieving and documenting information. Quality of care was improved through care scheduling individualised to resident needs, with reminders to avoid missed care. Relatives were reassured and activities were scheduled to loved one's preferences. The co-design implementation process was successful through commitment to quality from leadership teams and prioritising the focus on the holistic needs of the residents., Conclusion: A strong emphasis on co-design with care staff in developing and implementing the digital care system contributed to a system that supported nursing and care work, facilitated reporting and documentation, and improved resident care and well-being including identification of missed care., Relevance to Clinical Practice: Nurses, carers, administrators, and advocates can support the co-design creation of information systems that suit the workflow of an organisation and keep the focus on individualised models of care provision., (© 2022 The Authors.

Background: Small-scale models of dementia care are a potential solution to deinstitutionalize residential aged care and have been associated with improved resident outcomes, including quality of life and reduced hospitalizations for people living with dementia., Objective: This study aimed to generate strategies and ideas on how homes for people living with dementia in a village setting within a suburban community, could be designed and function without external boundaries. In particular, how could residents of the village and members of the surrounding community access and engage safely and equitably so that interpersonal connections might be fostered?, Methods: Twenty-one participants provided an idea for discussion at three Nominal Group Technique workshops, including people living with dementia, carers or former carers, academics, researchers, and clinicians. Discussion and ranking of ideas were facilitated in each workshop, and qualitative data were analyzed thematically., Results: All three workshops highlighted the importance of a surrounding community invested in the village; education and dementia awareness training for staff, families, services, and the community; and the necessity for adequately and appropriately trained staff. An appropriate mission, vision, and values of the organization providing care were deemed essential to facilitate an inclusive culture that promotes dignity of risk and meaningful activities., Conclusion: These principles can be used to develop an improved model of residential aged care for people living with dementia. In particular, inclusivity, enablement, and dignity of risk are essential principles for residents to live meaningful lives free from stigma in a village without external boundaries.

Objectives: Access to assistive technologies (ATs) is a human right for people with disabilities, but there are a range of barriers, including lack of adequate information. This review aimed to explore the implications of information asymmetry on the delivery of AT and to investigate if there are effective and equitable ways of providing AT brokerage services to people needing AT., Design: Scoping review., Data Sources: EBSCO Medline, EBSCO Cinahl, Academic Search Ultimate, Business Source Ultimate, Proquest Central, Scopus, Web of Science, PsychINFO, EconLit and JSTOR were searched through 18 July 2021., Eligibility Criteria: Intervention and observational studies and articles directly related to information asymmetry and brokerage in the context of AT were included. In addition, a scan of web-based resources and services was undertaken., Data Extraction and Synthesis: Four authors independently screened the articles for inclusion and performed a narrative synthesis., Results: Thirty-three articles were identified. The narrative synthesis showed that: (1) AT users want access to impartial information sources; (2) users want to be involved in AT selection; (3) users benefit from access to demonstration sites; (4) users want access to training and ongoing support in their use of AT; and (5) users want access to information on new and emerging technologies. Access to information and user engagement, we produced better outcomes and satisfaction. Web-based repositories are valuable for user research and peer feedback, while demonstration sites address the need for expert advice, trial use of equipment, training and support in equipment use and maintenance., Conclusions: Access to impartial information brokerage is critical to optimise AT selection. The implications of information asymmetry include lower user satisfaction, equipment underutilisation or abandonment. Aspects such as access to demonstration sites and web-based resources were also important., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Objective: To explore the gaps and anomalies in Australia's national aged care workforce data with a particular focus on casualisation and insecure employment in residential aged care., Methods: Secondary analysis of data from the National Aged Care Workforce Census and Surveys, the Aged Care Workforce Census and the Australian Bureau of Statistics Characteristics of Employment Survey., Results: There are significant and disturbing gaps in our knowledge of the aged care workforce deriving from disruptions to the time series as a result of methodological changes, reduced reliability resulting from declining response rates and the historical weighting system. Scope is also a critical factor due to data inadequacies relating to a non-Pay As You Go (non-PAYG) workforce and regarding the use of minimum hours contracts. This reduces our understanding of insecure employment., Conclusions: Australia needs better quality and more reliable data on its aged care workforce if the labour shortages confronting the sector are to be better understood and addressed. There is a critical need to determine the optimum strategy to obtain such data, whether by specific research projects of sufficient scale to accurately document the scale and scope of these issues, or in creative strategies to make use of automatically generated data., (© 2022 The Author.

Objective: The objective of this study was to test the reliability and validity of the Caregiver-Patient Activation Measure (CG-PAM)., Methods: Based on the psychometric testing of the original Patient Activation Measure (PAM), three assessments of reliability and validity were completed on the CG-PAM. Test-retest reliability was assessed across two weeks ( n = 23). Criterion validity was assessed by interviewing participants from the test-retest cohort ( n = 10), with transcripts assessed by subject matter experts ( n = 3) to classify activation levels of the interviewee. Construct validity was assessed through a survey ( n = 179) consisting of demographic questions, the CG-PAM and concepts hypothesised to be related to caregiver activation., Results: There was strong test-retest reliability ( r = 0.893), but poor criterion validity. Assessment o;f construct validity demonstrated significant relationships found between caregiver activation and weekly hours of care provided ( p < 0.001) , relationship satisfaction ( p < 0.001) , and dyad typology ( p < 0.001) , but not with perceived levels of stress or social support., Conclusion: The CG-PAM was found to have strong reliability, but there were inconsistent results across the validation tests conducted., Innovation: Future research must consider the dynamic nature of caring and the importance of the relationship between the caregiver/recipient when defining activation levels within the CG-PAM., Competing Interests: The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2022 The Authors.)

Objective: To identify outcomes of using health information technologies to support direct resident care in residential aged care homes, for residents, staff and services., Methods: In May 2022, a systematic search used CINAHL, Cochrane CRCT, MEDLINE, Proquest, PsychINFO and Scopus databases to locate papers published after 1990. Thematic analysis was used to synthesise extracted data. Results are reported using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement., Results: Of 3721 references imported for screening, 1017 duplicates were removed and 2609 excluded, leaving 95 papers for data extraction. The included articles were conducted in diverse residential care homes, and involved over 12,000 nurse, care assistant or resident participants. Thematic analysis identified a range of health information technologies were used for direct care in residential care settings, and outcomes focussed on acceptability, efficiency and success of implementation. Less frequent were outcomes focussed on residents and families, and the safety and quality-of-care delivery., Discussion: Staff outcomes, focussed on the satisfaction of staff and usability of the system, dominate in research examining health information technology used for direct care in residential aged care homes. Outcomes examining the use of health information technology in delivering improvements in resident health, well-being, quality and safety was limited. There is a need to increase using quality and safety of resident care as outcome measures., (Copyright © 2022 The Authors. Published by Elsevier B.V. All rights reserved.)

When older adults' driving abilities decline, automated driving technologies may improve community mobility, engagement, and independence. Most previous research has focused on older persons' attitudes rather than their use of automated driving technologies. This study examined older Australians' perceptions and experience of automated vehicle technologies before, during, and after a real-life driving experience, focusing on ease of use, usefulness, safety, acceptance, trust, and confidence. This mixed-methods study included observation of a 6-km test drive using a partially automated vehicle, pre- and post-drive questionnaires, and a post-drive semi-structured interview. Most participants reported positive perceptions and experiences before, during, and after the test drive. Visual analysis of pre/postresponses revealed divergent reactions to the test drive, consistent with the heterogeneity of the older population. Automated driving technologies have potential to contribute to mobility at older ages. Larger-scale studies including actual driving experiences are recommended.

Background: US nursing homes are required to follow Centers for Disease Control guidance for COVID-19 transmission-based precautions (TBP) when admitting COVID-positive patients., Objective: To assess how frequently nursing homes had shortages of personal protective equipment (PPE) or staffing in weeks when they admitted COVID-positive patients, which likely made it more difficult to follow TBP, and to compare facility characteristics by admissions practices., Design and Setting: Facility-level data from the Nursing Home COVID-19 Public File for the period between June 7, 2020 and March 7, 2021 was combined with additional data. The percentages of nursing homes that admitted COVID-positive patients and that had shortages when admitting were calculated for each week. Descriptive statistics and logistic regression models were used to examine the relationship between facility characteristics and the likelihood of admitting COVID-positive patients., Measurements: Facilities were categorized as having admitted COVID-positive patients in a week if one or more admissions requiring TBP were reported for that week. Facilities that reported having less than a 1-week supply of any type of PPE or being short any type of staff in a week were defined, respectively, as having a PPE shortage or staffing shortage in that week., Results: Over the 40-week study period, 39% of US nursing homes admitted COVID-positive patients in at least 1 week in which they were experiencing PPE or staffing shortages. Facilities that admitted COVID-positive patients with shortages generally had lower Centers for Medicare and Medicaid Services overall five-star ratings than other facilities. Only a small percentage of facilities that admitted COVID-positive patients while facing shortages were located in counties with severe shortages of PPE or staffing. In logistic regression models, shortages were not associated with COVID-positive admissions., Conclusion: The widespread practice of admitting COVID-positive patients while facing shortages may have put nursing home residents and staff at heightened risk of COVID-19 infection., (© 2021 The American Geriatrics Society.)

Given the high concentration of COVID-19 cases in long-term care (LTC) facilities in the United States, individuals working in these facilities are at heightened risk of SARS-CoV-2 exposure. Using data from the nationally-representative 2017 and 2018 National Health Interview Surveys on adults who reported working in LTC facilities, this study examines the extent to which LTC workers are also at increased risk or potentially at increased risk for severe illness from COVID-19 including hospitalization, intubation, or death. We used the Centers for Disease Control and Prevention's list of conditions placing individuals in these risk categories to the extent possible. We also examined the sociodemographic characteristics of LTC workers by occupation and COVID-19 illness severity risk status. One percent (552 out of 52,159) of the weighted NHIS sample worked in LTC facilities. Workers in LTC facilities were disproportionately Black, female, and low income. Half of LTC workers (50%) were at increased risk of severe illness from COVID-19 and another 19.6% were potentially at increased risk. There were few significant differences in demographic characteristics between risk groups, though those at increased risk had lower educational attainment and recent trouble affording prescription medications. Despite the high degree of vulnerability of both LTC residents and workers to severe illness from COVID-19, many LTC facilities still have inadequate supplies of personal protective equipment and COVID-19 tests. Given that state budget deficits due to the COVID-19 pandemic limit the potential for state actions, enhanced federal efforts are needed to protect LTC residents and staff from COVID-19., (Copyright © 2020 Elsevier Inc.

Significance: Estimating a broader set of measures of local eye care provider availability than used in prior research offers information that is useful for policy decisions related to access to eye care., Purpose: The purpose of this study was to examine whether policy-relevant information was gained when measures of local eye care provider availability in addition to the estimated travel time (ETT) to the closest provider were estimated for the population 65 years or older in Kentucky, New Mexico, and Oklahoma. These states have expanded surgical scope of practice for optometrists., Methods: This study used block group-level population data from the 2010 U.S. Decennial Census and eye care provider office address information from the 2016 Medicare Provider Utilization and Payment Data. Geographic information system analysis was used to calculate ETTs between individuals and eye care providers. Expanded measures of availability included the difference in ETT to an individual's second closest and closest ophthalmologist, the difference in ETT to an individual's closest ophthalmologist and closest optometrist, and whether only one ophthalmologist at the closest office accepted Medicare. Descriptive statistics were calculated for each state and by urbanicity., Results: Of the population 65 years or older in each state, between 10.8 (Kentucky) and 16.6% (Oklahoma) had a one-way ETT to the second closest ophthalmologist >15 minutes longer than to the closest ophthalmologist, between 21.1 (Kentucky) and 27.6% (Oklahoma) had a one-way ETT to the closest ophthalmologist >15 minutes longer than to the closest optometrist, and between 56.4 (Kentucky) and 70.0% (Oklahoma) had only one ophthalmologist at the closest office who accepted Medicare. Findings differed substantially by urbanicity., Conclusions: Using a portfolio of travel time-based measures enhances the understanding of local eye care provider availability.

This paper examines adaptive device use among two samples of U.S. adults aged 40 years and older with age-related macular degeneration, diabetic retinopathy, glaucoma or cataracts from the 2008 and 2016 waves of the nationally-representative cross-sectional National Health Interview Survey (n = 2875 and n = 6233 respectively). Individuals who replied affirmatively to the question, "do you use any adaptive devices such as telescopic or other prescriptive lenses, magnifiers, large print or talking materials, CCTV, white cane or guide dogs?" were defined as adaptive device users. Descriptive statistics and logistic regression models of adaptive device use were estimated. The main regression models used 2008 data and included explanatory variables for vision-related limitations, other functional limitations, sociodemographic characteristics and the local availability of ophthalmologists and optometrists. 6.1% of the 2008 sample and 4.2% of the 2016 sample used adaptive devices, these percentages were significantly different. 31.4% of the 2008 sample and 24.0% of 2016 sample with multiple vision-related limitations used adaptive devices, these percentages were not significantly different. Based on previous research, adaptive device use among the subgroups with multiple vision-related limitations would be expected to improve functional ability. In the regression models, the likelihood of adaptive device use increased significantly with the number of vision-related limitations, family income and local ophthalmologist availability. The regression results provide evidence of socioeconomic and geographic disparities in adaptive device use in the U.S. Together the descriptive statistics and regression results suggest that public health strategies to increase access to adaptive devices are needed.

This paper examines the patterns of visits to primary care and eye care providers for annually recommended diabetes preventive care services over a two-year period in a sample of U.S. adults aged 18years and older with diabetes drawn from the 2008-2013 Medical Expenditure Panel Survey-Household Component (n=3982). The four-category outcome variable was defined based on the four possible combinations of whether an individual missed an annual visit to a primary care provider for preventive care services in at least one year over the two-year period and whether the individual missed an annual visit to an eye care provider in at least one year over this period. Descriptive statistics and a multinomial logistic regression model were estimated. 51.9% of the sample missed an annual visit to a primary care or eye care provider for preventive care services over a two-year period. Although 48.8% of the sample missed at least one annual visit to an eye care provider, 85.6% of these individuals did visit a primary care provider for preventive care services during the year they did not visit an eye care provider. This suggests that primary care-based screening for diabetic retinopathy could reach most individuals who do not receive regular eye care. Regression results particularly relevant for potential interventions were that missing annual visits was significantly more likely for individuals without health insurance or a usual source of healthcare and for those who were not receiving diabetes treatments and did not have or were not aware of having diabetes-related complications., (Copyright © 2017 Elsevier Inc.

Background: Persons with dementia (PWD) often have complex medication regimens and are at risk of medication problems during the multiple transitions of care experienced as the condition progresses., Objectives: To explore medication processes in acute care episodes and care transitions for PWD and to make recommendations to improve practice., Method: Semi-structured interviews were conducted by two pharmacy researchers from a focused purposive sample of fifty-one participants (carers, health professionals, Alzheimer's Australia staff) from urban and rural Australia. After written consent, the interviews were audio-recorded then transcribed verbatim for face-to-face interviews, or notes were taken during the interview if conducted by telephone. The transcripts were checked for accuracy by the pharmacy researchers. Thematic analysis of the data was undertaken independently by the two researchers to reduce bias and any disagreements were resolved by discussion., Results: Themes identified were: medication reconciliation; no modified planning for care transitions; underutilization of information technology; multiple prescribers; residential aged care facilities; and medication reviews by pharmacists. Sub themes were: access to appropriate staff; identification of dementia; dose administration aids; and staff training., Conclusions: Medication management is sub-optimal for PWD during care transitions and may compromise safety. Suggested improvements included: increased involvement of pharmacists in care transitions; outreach or transitional health care professionals; modified planning for care transitions for individuals over 80 years; co-ordinated electronic records; structured communication; and staff training., (Copyright © 2016 Elsevier Inc.

Increasingly, public sector programmes respond to complex social problems that intersect specific fields and individual disciplines. Such responses result in multi-site initiatives that can span nations, jurisdictions, sectors and organisations. The rigorous evaluation of public sector programmes is now a baseline expectation. For evaluations of large and complex multi-site programme initiatives, the processes of ethics review can present a significant challenge. However in recent years, there have been new developments in centralised ethics review processes in many nations. This paper provides the case study of an evaluation of a national, inter-jurisdictional, cross-sector, aged care health initiative and its encounters with Australian centralised ethics review processes. Specifically, the paper considers progress against the key themes of a previous five-year, five nation study (Fitzgerald and Phillips, 2006), which found that centralised ethics review processes would save time, money and effort, as well as contribute to more equitable workloads for researchers and evaluators. The paper concludes with insights for those charged with refining centralised ethics review processes, as well as recommendations for future evaluators of complex multi-site programme initiatives., (Copyright © 2015 Elsevier Ltd.

Objective: To describe the patterns of local eye care provider availability in the US., Methods: Data from 2011 on the number of ophthalmologists and optometrists in each of the 3143 counties in the US were drawn from the Area Health Resources File. Population-weighted quartiles of the county-level number of ophthalmologists per capita and the county-level number of optometrists per capita were defined. Descriptive statistics were calculated and a cross tabulation of quartiles of ophthalmologist availability and quartiles of optometrist availability was conducted for all the counties in the US and for the set of counties in each region of the US., Results: 24.0% of US counties had no ophthalmologists or optometrists. 60.7% of counties in the US were in one of the lower two quartiles of both ophthalmologist availability and optometrist availability, and 24.1% of counties were in one of the lower two quartiles of ophthalmologist availability but in one of the upper two quartiles of optometrist availability., Conclusions: Public health interventions that are effective in a context of limited local eye care provider availability or that are able to leverage optometrist availability effectively in areas with limited ophthalmologist availability could be of widespread use in the US., (Copyright © 2015 Elsevier Inc.

Aims: To describe the availability of aged care and dementia services in public hospitals in New South Wales (NSW), Australia in 2006/2007., Method: Hospitals were surveyed about issues relevant to dementia in acute care including the types of aged care wards and staff, policies, practices, clinics, community services and resources for dementia care., Results: Responses were obtained from 163 hospitals (82%); responding hospitals represented 93.4% of NSW hospital beds, 96.7% of multiday episodes of care. Hospitals that had a Specialist Mental Health Service for Older People (SMHSOP) and an Aged Care Service (ACS) had the highest levels of dementia-related services and policies. Few hospitals without ACS or SMHSOP had clinics for dementia assessment, secure beds for disturbed behaviour, or services to manage patients with dementia and medical or behavioural comorbidity in the community., Conclusion: Dementia services in NSW hospitals are closely aligned with ACS and SMHSOP, with limited dementia services in hospitals without ACS or SMHSOP., (© 2013 The Authors.

IMPORTANCE Understanding whether differences in the local availability of eye care professionals are related to differences in realized access to eye care is important for assessing whether and where public health efforts are needed to increase access to eye care professionals. OBJECTIVE To examine whether the county-level availability of ophthalmologists and optometrists is associated with measures of realized access to eye care for individuals with diabetes mellitus, diabetic retinopathy, or age-related macular degeneration (ARMD). DESIGN, SETTING, AND PARTICIPANTS We studied a cross-sectional sample of US adults 40 years and older (1098 individuals with diabetes, 345 with diabetic retinopathy, and 498 with ARMD) from the 2005-2008 National Health and Nutrition Examination Survey. MAIN OUTCOMES AND MEASURES Outcomes were whether diabetic individuals reported undergoing a dilated eye examination in the past year, whether individuals were unaware they had diabetic retinopathy, whether diabetic individuals had vision-threatening diabetic retinopathy, and whether individuals were unaware they had ARMD. RESULTS In logistic regression models that also included individual characteristics, individuals who lived in a county in the highest ophthalmologist availability quartile were less likely to be unaware they had diabetic retinopathy (predictive margin [PM], 66.1%; 90% CI, 48.8%-83.4%; vs PM, 84.1%; 90% CI, 78.7%-89.6%) and were less likely to have vision-threatening diabetic retinopathy (PM, 1.4%; 90% CI, 0.9%-1.9%; vs PM, 2.6%; 90% CI, 1.8%-3.4%) than individuals who lived in a county in the lower 3 ophthalmologist availability quartiles. Individuals who lived in a county in the lowest ophthalmologist availability quartile were more likely to be unaware they had ARMD (PM, 93.8%; 90% CI, 90.6%-97.0%; vs PM, 88.3%; 90% CI, 84.7%-91.9%) than individuals who lived a county in the higher 3 ophthalmologist availability quartiles. Optometrist availability quartiles were not significantly related to any of the outcomes. CONCLUSIONS AND RELEVANCE The results suggest that efforts to increase access to ophthalmologists to improve outcomes related to diabetic retinopathy or to increase awareness of ARMD should focus on improving access for diabetic individuals who live in counties in the lowest 3 quartiles of ophthalmologist availability and on individuals at risk of ARMD who live in counties in the lowest quartile of ophthalmologist availability.

We analyze the relationship between prenatal WIC participation and birth outcomes in New York City from 1988-2001. The analysis is unique for several reasons. First, we have over 800,000 births to women on Medicaid, the largest sample ever used to analyze prenatal participation in WIC. Second, we focus on measures of fetal growth distinct from preterm birth, since there is little clinical support for a link between nutritional supplementation and premature delivery. Third, we restrict the primary analysis to women on Medicaid who have no previous live births and who initiate prenatal care within the first four months of pregnancy. Our goal is to lessen heterogeneity between WIC and non-WIC participants by limiting the sample to highly motivated women who have no experience with WIC from a previous pregnancy. Fourth, we analyze a large sub-sample of twin deliveries. Multifetal pregnancies increase the risk of anemia and fetal growth retardation and thus may benefit more than singletons from nutritional supplementation. We find no relationship between prenatal WIC participation and measures of fetal growth among singletons. We find a modest pattern of association between WIC and fetal growth among U.S.-born Black twins. Our findings suggest that prenatal participation in WIC has had a minimal effect on adverse birth outcomes in New York City.

This paper examines the relation between long-term Food Stamp Program (FSP) participation and overweight in children using data on children from the National Longitudinal Survey of Youth 1979 Child Sample. A child was categorized as overweight if his or her BMI was >/= the 95th percentile of sex- and age-specific BMI. The data were arranged as a panel with multiple observations per child, and the preferred models of overweight included long-term FSP participation, additional demographic, socioeconomic, and environmental characteristics, and child fixed effects. Child fixed effects were used to take into account unobserved differences across children that did not vary over time. The models were estimated separately for younger (5-11 y old) and older (12-18 y old) children. In Ordinary Least Squares models, long-term FSP participation was positively and significantly related to overweight in young girls (P = 0.048), and negatively and significantly related to overweight in young boys (P = 0.100). Compared with girls and boys whose families did not participate in the FSP during the previous 5 y, FSP participation during all of the previous 5 y was associated with a 42.8% increase for young girls and a 28.8% decrease for young boys in the predicted probability of overweight. Long-term FSP participation was not significantly related to overweight in older children. Although these models did not control for food insecurity, the potential role of food insecurity in FSP participation was considered in the interpretation of the relation between FSP participation and child weight.

This study examined the relationship between Food Stamp Program (FSP) participation and the obesity of low income individuals using data from the National Longitudinal Survey of Youth 1979. Obesity was defined as body mass index >or= 30 kg/m(2). The data were arranged as a panel with multiple observations per individual, and the models of obesity included current and long-term FSP participation, additional demographic, socioeconomic and environment characteristics and individual fixed effects. Individual fixed effects were used to take into account unobserved differences across individuals that did not vary over time. In ordinary least squares models, current and long-term FSP participation were significantly related to the obesity of low income women (P < 0.05), but not of low income men. For low income women, current participation in the FSP was associated with a 9.1% increase in the predicted probability of current obesity. Participation in the FSP in each of the previous five years compared to no participation over that time period was associated with approximately a 20.5% increase in the predicted probability of current obesity. These models did not control for food insecurity, and this omission potentially complicates the interpretation of the FSP participation variables.
