Factors associated with blood mercury concentrations and their interactions with three glutathione S-transferase genes (GSTT1, GSTM1, and GSTP1): an exposure assessment study of typically developing Jamaican children.

BACKGROUND: Jamaican soil is abundant in heavy metals including mercury (Hg). Due to availability and ease of access, fish is a traditional dietary component in Jamaica and a significant source of Hg exposure. Mercury is a xenobiotic and known neuro-toxicant that affects children's neurodevelopment. Human glutathione S-transferase (GST) genes, including GSTT1, GSTM1, and GSTP1, affect Hg conjugation and elimination mechanisms. METHODS: In this exposure assessment study we used data from 375 typically developing (TD) 2-8-year-old Jamaican children to explore the association between environmental Hg exposure, GST genes, and their interaction effects on blood Hg concentrations (BHgCs). We used multivariable general linear models (GLMs). RESULTS: We identified the child's age, consumption of saltwater fish, canned fish (sardine, mackerel), string beans, grain, and starches (pasta, macaroni, noodles) as the environmental factors significantly associated with BHgCs (all P < 0.05). A significant interaction between consumption of canned fish (sardine, mackerel) and GSTP1 in relation to BHgC using either a co-dominant or recessive genetic model (overall interaction P = 0.01 and P < 0.01, respectively) indicated that consumption of canned fish (sardine, mackerel) was significantly associated with higher mean BHgC only among children with the GSTP1 Ile105Val, Ile/Ile [Ratio of mean Hg (95% CI) = 1.59 (1.09, 2.32), P = 0.02] and Ile/Val [Ratio of mean Hg (95% CI) = 1.46 (1.12, 1.91), P = 0.01] genotypes. CONCLUSIONS: Since this is the first study from Jamaica to report these findings, replication in other populations is recommended.

Seroprevalence of Human T-Cell Lymphotropic Virus-1 in a Jamaican Antenatal Population and Assessment of Pooled Testing as a Cost Reduction Strategy for Implementation of Routine Antenatal Screening.

Mother to child transmission (MTCT) of human T-cell lymphotropic virus (HTLV)-1 is associated with increased risk of adult T-cell leukemia and can be unrecognized without routine antenatal screening. We assessed the seroprevalence of HTLV-1/2 among pregnant women attending The University Hospital of the West Indies Antenatal Clinic, 2019, and validated a cost-effective strategy to screen antenatal clinic attendees for HTLV-1/2. Residual antenatal samples from 370 women were tested for HTLV-1/2 by chemiluminescence microparticle immunoassay (CMIA). Six samples were confirmed HTLV-1 positive by Western blot (none for HTLV-2) for a prevalence of 1.62%. Four mother-child pairs were able to be recruited for HTLV testing of children, with two children testing HTLV-1/2 positive. Medical records of HTLV-1-infected women revealed that all women breastfed, indicating an unrecognized risk for HTLV MTCT. To assess whether pooling of samples as a cost-reduction strategy could be introduced, we pooled all antenatal samples received between November and December 2021 into 12 pools of eight samples/pool. Two pools were CMIA positive, and de-pooling of samples identified two CMIA-positive samples (one per pool), both confirmed as HTLV-1 by Western blot. These results indicate that HTLV-1 remains prevalent in pregnant Jamaican women and that sample pooling can be a cost-effective strategy to limit MTCT in Jamaica.

Supporting Culturally Responsive Assessment Practices With Preschoolers: Guidance From Methods in the Jamaican Context.

PURPOSE: There is a shortage of available methods to accurately inform the developmental status of children whose cultural and linguistic backgrounds vary from the mainstream. The purpose of this review article was to describe different approaches used to support the accurate characterization of speech, language, and functional communication in children speaking Jamaican Creole and English, an understudied paradigm in the speech pathology research. METHOD: Approaches used across four previously published studies in the Jamaican Creole Language Project are described. Participants included 3- to 6-year-old Jamaican children (n = 98-262) and adults (n = 15-33). Studies I and II described validation efforts about children's functional communication using the Intelligibility in Context Scale (ICS; speech) and the Focus on the Outcomes of Communication Under Six (FOCUS; speech and language). Study III described efforts to accurately characterize difference and disorder in children's expressive grammar using adapted scoring, along with adult models to contextualize child responses. Last, Study IV applied acoustic duration (e.g., whole word) and an adapted scoring protocol to inform variation in speech sound productions in the Jamaican context where a post-Creole continuum exists. RESULTS: Studies I and II offered promising psychometric evidence about the utility of the ICS and the FOCUS. Study III revealed strong sensitivity and specificity in classifying difference and disorder using adult models. Last, in Study IV, linguistically informed acoustic analyses and an adapted protocol captured variation in speech productions better than a standard approach. CONCLUSIONS: Applying culturally responsive methods can enhance the accurate characterization of speech, language, and functional communication in Jamaican children. The innovative methods used offer a model approach that could be applied to other linguistic contexts where a mismatch exists between speech-language pathologists and their clientele.

The Irie Classroom Toolbox: Mixed method assessment to inform future implementation and scale-up of an early childhood, teacher-training, violence-prevention programme.

Introduction: Violence against children (VAC) is a violation of child rights, has high prevalence in low- and middle-income countries, is associated with long-term negative effects on child functioning, and with high economic and social costs. Ending VAC at home and at school is thus a global public health priority. Methods: In Jamaica, we evaluated an early childhood, teacher-training, violence-prevention programme, (the Irie Classroom Toolbox), in a cluster-randomised trial in 76 preschools. The programme led to large reductions to teachers' use of VAC, although the majority of teachers continued to use VAC at times. In this paper, we describe a mixed-method evaluation of the Irie Classroom Toolbox in the 38 Jamaican preschools that were assigned to the wait-list control group of the trial. In a quantitative evaluation, 108 preschool teachers in 38 preschools were evaluated at pre-test and 91 teachers from 37 preschools were evaluated at post-test. One preschool teacher from each of these 37 preschools were randomly selected to participate in an in-depth interview as part of the qualitative evaluation. Results: Preschool teachers were observed to use 83% fewer instances of VAC across one school day after participating in the programme, although 68% were observed to use VAC at least once across two days. The qualitative evaluation confirmed these findings with all teachers reporting reduced use of violence, but 70% reporting continued use of VAC at times. Teachers reported that the behaviour change techniques used to deliver the intervention increased their motivation, knowledge and skills which in turn led to improved child behaviour, improved relationships and improved professional well-being. Direct pathways to reduced use of VAC by teachers were through improved child behaviour and teacher well-being. The main reasons for continued use of VAC were due to barriers teachers faced using positive discipline techniques, teachers' negative affect, and child behaviours that teachers perceived to be severe. Discussion: We describe how we used the results from the mixed-method evaluation to inform revisions to the programme to further reduce teachers' use of VAC and to inform the processes of training, supervision and ongoing monitoring as the programme is scaled-up through government services.

Expenditures on sugar-sweetened beverages in Jamaica and its association with household budget allocation.

BACKGROUND: Sugar-sweetened beverages (SSB) consumption is associated with overweight and obesity, which are important drivers for the increasing healthcare and other social costs. If expenditures on SSB decrease expenditures on other goods and services, such as education and healthcare, this "crowding-out" may have a lasting effect. The main objectives of this article are, first, to estimate the statistical association between the decision of spending in SSB and several households' sociodemographic characteristics; and second, to estimate the association between the decision of buying SSB and budget allocation across categories in Jamaica. METHODS: Using the Jamaican Household Expenditure Survey 2004-2005 a generalized ordered probit model was estimated to examine the association between socioeconomic variables and the decision to spend on SSB. Seemingly Unrelated Regression Equations (SURE) of all the expenditure groups (except the SSB group) were used to estimate the association between the decision of buying SSB and budget allocation on other goods and services. RESULTS: Expenditures on SSB are negatively affected by the size of the household and the area of residence (rural households spend more on SSB than urban ones), while having a larger proportion of children (15 or younger) and having a larger total budget is associated to more expenditures on SSB. Households with positive expenditure on SSB allocate significantly less budget to "Healthcare" and "Education", when compared to those who did not buy SSB. CONCLUSIONS: SSB expenditures may displace expenditures in necessary goods and services, which implies that decreasing the proportion of budget spent on SSB may have important present and future consequences on poorer households' human capital accumulation and future incomes.

An assessment of the impact of 1.5 versus 2 and 2.5°C global temperature increase on flooding in Jamaica: a case study from the Hope watershed.

Climate change models project that, within the Caribbean basin, rainfall intensity is likely to increase toward the end of this century, although the region is projected to be drier overall. This may affect the frequency and severity of floods in Jamaica and the Caribbean Small Island Developing States. We investigate how flood hazards may be affected by increases in global mean surface temperature of 1.5, 2.0 and 2.5°C above pre-industrial levels using a case study of a Jamaican watershed. Rainfall projections from the PRECIS regional climate model for the Caribbean are analysed. Six members from the Quantifying Uncertainty in Model Predictions (AENWH, AEXSA, AEXSC, AEXSK, AEXSL and AEXSM) were used to create 100-year flood inundation maps for the Hope river for different global warming levels using hydrological and hydraulic models. Model runs projected peak discharges at 2.0, 2.5 and 1.5°C warming that were higher than discharges in the historical record of events that damaged sections of the watershed. Projections from the hydraulic model show increased flow area, depth and extent for 1.5 followed by 2.0 and 2.5°C rises in temperature. These results imply continued flood risk for the vulnerable areas of the watershed. This article is part of the theme issue 'Developing resilient energy systems'.

A Monte Carlo based approach to the resource assessment of Jamaica's geothermal energy potential.

The Eastern Caribbean chain of islands is commonly known to exhibit high-enthalpy systems for geothermal energy exploitation. The northernmost Caribbean Community member state of Jamaica possesses physical manifestations of 12 hot springs across the island. Previous investigations indicate that of the potential 12 hot springs, Bath, Windsor and Milk River springs have cogent geothermometry of their thermal fluids with estimated temperature ranges of (80-102°C), (128-156°C), and (158-206°C), respectively. The paper provides numerical findings for each geothermal system of interest and performs Monte Carlo simulations to optimize calculated findings. The determined quantitative findings are considered under the context of environmental savings and policy regime conditions for driving geothermal energy development. The three areas of interest are situated within the Rio Minho Basin, the Dry Harbour Mountains and the Blue Mountain South Basin. Through the consideration of a 25-year lifetime for production, a collective total of 94.81 MWe of geothermal power reserves can be absorbed into the national energy mix, displacing an estimated 0.38 million barrels of oil imports, resulting in approximately 0.44 million tonnes of carbon dioxide emissions being avoided per year. This article is part of the theme issue 'Developing resilient energy systems'.

The impact of financial development on carbon dioxide emissions in Jamaica.

We determine the possible impacts of changes in financial development on carbon dioxide (CO2) emissions in Jamaica for the period 1980 to 2018, with special attention given to the possible existence of asymmetries in this relationship. There are three major findings. First, there is a unique cointegrating relationship among the variables where CO2 emissions are a function of financial development, real domestic economic activity, and trade openness. Financial development negatively impacts CO2 emissions in this relationship, even though CO2 emissions are impacted positively by rising levels of real domestic economic activity and trade openness. Second, there is an asymmetric impact of changes in financial development in the long run and short run on changes in CO2 emissions. Third, positive and negative changes in financial development Granger cause CO2 emissions in the short run. One policy implication of these findings is that strengthening the negative relationship between CO2 emissions and financial development could lessen the increase in CO2 emissions associated with rising levels of real domestic economic activity.

Prevención y control de las enfermedades no transmisibles en Jamaica: El caso a favor de la inversión

En Jamaica, las enfermedades no transmisibles (ENT) son la causa principal de la morbilidad y la mortalidad. Además de la carga que imponen sobre la salud, también representan una carga significativa para la economía nacional, ya que su tratamiento genera gastos elevados y las personas que los sufren son más propensas al abandono del ejercicio de la profesión, al absentismo o a trabajar con capacidad reducida. Además, los elevados costos de tratamiento imponen una carga económica directa al sistema de salud, la sociedad y el Estado, que puede llevar a una reducción de la inversión en ámbitos como la educación y el capital físico que, a la larga, aumentan el producto interno bruto (PIB). Con el propósito de ayudar a fortalecer la capacidad de los Estados Miembros para generar y utilizar evidencia económica sobre las ENT, la Organización Panamericana de la Salud (OPS) se asoció con el Ministerio de Salud de Jamaica, la Organización Mundial de la Salud (OMS), el Programa de las Naciones Unidas para el Desarrollo (PNUD) y RTI International para elaborar un caso a favor de la inversión en la prevención y el control de las ENT en Jamaica. Este proyecto aporta evidencia y orientación para apoyar la formulación, el financiamiento y la implementación de estrategias nacionales multisectoriales de prevención y control de las ENT. En concreto, calcula el rendimiento de la inversión en la implementación de intervenciones de política para el control del tabaco y el consumo nocivo de alcohol, así como intervenciones clínicas para disminuir las ENT, específicamente, las enfermedades cardiovasculares y la diabetes. También evalúa la viabilidad política de poner en marcha estas medidas.

Palliative care integration: a critical review of nurse migration effect in Jamaica.

BACKGROUND: Provision of palliative care to individuals with late-stage serious illnesses is critical to reduce suffering. Palliative care is slowly gaining momentum in Jamaica but requires a highly skilled workforce, including nurses. Out-migration of nurses to wealthier countries negatively impacts the delivery of health care services and may impede palliative care capacity-building. This critical review aimed to explore the evidence pertaining to the nurse migration effect on the integration of palliative care services in Jamaica and to formulate hypotheses about potential mitigating strategies. METHODS: A comprehensive search in the PubMed, CINAHL, and ProQuest PAIS databases aimed to identify articles pertinent to nurse migration in the Caribbean context. Grant and Booth's methodologic framework for critical reviews was used to evaluate the literature. This methodology uses a narrative, chronologic synthesis and was guided by the World Health Organization (WHO) Public Health Model and the Model of Sustainability in Global Nursing. RESULTS: Data from 14 articles were extracted and mapped. Poorer patient outcomes were in part attributed to the out-migration of the most skilled nurses. 'Push-factors' such as aggressive recruitment by wealthier countries, lack of continuing educational opportunities, disparate wages, and a lack of professional autonomy and respect were clear contributors. Gender inequalities negatively impacted females and children left behind. Poor working conditions were not necessarily a primary reason for nurse migration. Four main themes were identified across articles: (a) globalization creating opportunities for migration, (b) recruitment of skilled professionals from CARICOM by high income countries, (c) imbalance and inequities resulting from migration, and (d) mitigation strategies. Thirteen articles suggested education, partnerships, policy, and incentives as mitigation strategies. Those strategies directly align with the WHO Public Health Model drivers to palliative care integration. CONCLUSION: Emerged evidence supports that nurse migration is an ongoing phenomenon that strains health systems in Caribbean Community and Common Market (CARICOM) countries, with Jamaica being deeply impacted. This critical review demonstrates the importance of strategically addressing nurse migration as part of palliative care integration efforts in Jamaica. Future studies should include targeted migration mitigation interventions and should be guided by the three working hypotheses derived from this review.

Annual Report 2020. Universal Health and the Pandemic. Resilient Health Systems. Jamaica, Bermuda, and the Cayman Islands

Founded in 1902 as the independent specialized health agency of the inter-American system, the Pan American Health Organization (PAHO) has developed recognized competence and expertise, providing technical cooperation to its Member States to fight communicable and noncommunicable diseases and their causes, to strengthen health systems, and to respond to emergencies and disasters throughout the Region of the Americas. In addition, acting in its capacity as the World Health Organization’s Regional Office, PAHO participates actively in the United Nations Country Team, collaborating with other agencies, the funds and programs of the United Nations system to contribute to the achievement of the Sustainable Development Goals (SDGs) at country level. This 2020 annual report reflects PAHO’s technical cooperation in the country for the period, implementing the Country Cooperation Strategy, responding to the needs and priorities of the country, and operating within the framework of the Organization’s regional and global mandates and the SDGs. Under the overarching theme of Universal Health and the Pandemic – Resilient Health Systems, it highlights PAHO’s response to the COVID-19 pandemic as well as its continuing efforts in priority areas such as communicable diseases, noncommunicable diseases, mental health, health throughout the life course, and health emergencies. It also provides a financial summary for the year under review.

Implementing Palliative Care Training in the Caribbean: Development and Assessment of a Basic Palliative Care Training Course in Jamaica.

CONTEXT: The majority of people in need of palliative care (PC) in low- and middle-income countries lack access to it and suffer unnecessarily as a consequence. This unmet need is due, in part, to the lack of trained PC providers. OBJECTIVES: This study aims to assess the effects of regional training in PC for doctors, nurses, and pharmacists in the Caribbean through assessment of participant satisfaction, anticipated course impact on participants' clinical practice, barriers to changing practice, and perceived course impact on achievement of key PC milestones. METHODS: We created and taught a course in basic PC for clinicians from the Caribbean region and collected and analyzed postcourse quantitative and qualitative data on satisfaction and expected impact. RESULTS: Eighty-three clinicians from five Caribbean countries participated in this workshop. Thirty participants completed the post-course survey. One hundred percent of these participants ranked the quality of the course as "very high quality" or "high quality." The majority of participants anticipated changing their practice as a result of this course. Several barriers were reported, including lack of formal PC training in participants' home countries. Results of participants' retrospective pre- and postcourse self-assessment for achievement of key PC milestones showed a statistically significant mean increase of at least one point on the seven-point Likert scale for each milestone. CONCLUSION: Overall satisfaction with the course was high, and self-assessed competency in PC improved. These data suggest that an intensive training over several days is an effective format for increasing providers' perceived efficacy in delivering PC.

Social determinants of multimorbidity in Jamaica: application of latent class analysis in a cross-sectional study.

BACKGROUND: Non-communicable disease (NCD) multimorbidity is associated with impaired functioning, lower quality of life and higher mortality. Susceptibility to accumulation of multiple NCDs is rooted in social, economic and cultural contexts, with important differences in the burden, patterns, and determinants of multimorbidity across settings. Despite high prevalence of individual NCDs within the Caribbean region, exploration of the social epidemiology of multimorbidity remains sparse. This study aimed to examine the social determinants of NCD multimorbidity in Jamaica, to better inform prevention and intervention strategies. METHODS: Latent class analysis (LCA) was used to examine social determinants of identified multimorbidity patterns in a sample of 2551 respondents aged 15-74 years, from the nationally representative Jamaica Health and Lifestyle Survey 2007/2008. Multimorbidity measurement was based on self-reported presence/absence of 11 chronic conditions. Selection of social determinants of health (SDH) was informed by the World Health Organization's Commission on SDH framework. Multinomial logistic regression models were used to estimate the association between individual-level SDH and class membership. RESULTS: Approximately one-quarter of the sample (24.05%) were multimorbid. LCA revealed four distinct profiles: a Relatively Healthy class (52.70%), with a single or no morbidity; and three additional classes, characterized by varying degrees and patterns of multimorbidity, labelled Metabolic (30.88%), Vascular-Inflammatory (12.21%), and Respiratory (4.20%). Upon controlling for all SDH (Model 3), advancing age and recent healthcare visits remained significant predictors of all three multimorbidity patterns (p < 0.001). Private insurance coverage (relative risk ratio, RRR = 0.63; p < 0.01) and higher educational attainment (RRR = 0.73; p < 0.05) were associated with lower relative risk of belonging to the Metabolic class while being female was a significant independent predictor of Vascular-Inflammatory class membership (RRR = 2.54; p < 0.001). Material circumstances, namely housing conditions and features of the physical and neighbourhood environment, were not significant predictors of any multimorbidity class. CONCLUSION: This study provides a nuanced understanding of the social patterning of multimorbidity in Jamaica, identifying biological, health system, and structural determinants as key factors associated with specific multimorbidity profiles. Future research using longitudinal designs would aid understanding of disease trajectories and clarify the role of SDH in mitigating risk of accumulation of diseases.

Associations of neighborhood physical and crime environments with obesity-related outcomes in Jamaica.

OBJECTIVE: To examine whether proximity and density of public open spaces, public parks, street connectivity, and serious and violent crimes were associated with Body Mass Index (BMI) and Waist Circumference (WC) within and across levels of urbanicity, sex and socioeconomic status (SES) in Jamaica, a small island developing state (SIDS). METHODS: Secondary analysis was conducted using data from the Jamaica Health and Lifestyle Survey 2008 (JHLS II). All respondents were geocoded to area of residence in Enumeration Districts (EDs). Intraclass correlation coefficients (ICCs) were derived and multilevel mixed effects regression models applied to 2529 participants nested within 101 EDs from all 14 parishes in Jamaica. RESULTS: There was significant clustering across neighborhoods for mean BMI (ICC = 4.16%) and mean WC (ICC = 4.42%). In fully adjusted models statistically significant associations included: increased mean BMI among men, with increased intersection density/ km2 (ß = 0.02; 95% CI = 1.96 x10-3, 0.04, p = 0.032); increased mean WC among urban residents with increased crimes/km2/yr (ß = 0.09; 95% CI = 0.03, 0.16, p<0.01) and among persons in the middle class, with further distance away from public parks (ß = 0.30; 95% CI = 0.08, 0.53, p<0.01). CONCLUSIONS: Neighborhood physical and crime environments were associated with obesity-related outcomes in Jamaica. Policymakers in SIDS such as Jamaica should also note the important differences by urbanicity, sex and SES in prevention efforts designed to stem the growing obesity epidemic.

Foreign investment in emerging legal medicinal cannabis markets: the Jamaica case study.

INTRODUCTION: The establishment of a legal market for medicinal cannabis under the Dangerous Drugs Amendment Act 2015 has positioned Jamaica at the forefront of cannabis law reform in the developing world. Many local cannabis businesses have attracted investment from overseas, including from Canada, US and Europe. AIM: To explore the opportunities and risks of foreign investment in an emerging domestic legal cannabis market in a developing country. METHODS: Thematic analysis of semi-structured face-to-face interviews with 22 key informants (KIs) from the Jamaican government, local cannabis industry, academia and civil society, and field observations of legal and illegal cannabis cultivators. RESULTS: KIs from the Jamaican public agencies and domestic cannabis entrepreneurs saw foreign investment as an essential source of capital to finance the start-up costs of legal cannabis businesses. Local cannabis entrepreneurs prioritised investors with the greatest financial resources, brand reputation and export networks. They also considered how allied an investor was with their business vision (e.g., organic cultivation, medical vs. recreational). The key benefits of partnering with a foreign investor included transfer of technical knowledge and financial capital, which enhanced production, quality assurance and seed-to-sale tracking. Some KIs expressed concern over investors' focus on increasing production efficiency and scale at the expense of funding research and development (R&D) and clinical trials. KIs from the local industry, government agencies and civil society highlighted the risks of 'predatory' shareholder agreements and domestic political interference. Concerns were raised about the impact of foreign investment on the diversity of the domestic cannabis sector in Jamaica, including the commitment to transition traditional illegal small-scale cannabis cultivators to the legal sector. CONCLUSION: While foreign investment has facilitated the commercialisation of the cannabis sector in Jamaica, regulatory measures are also needed to protect the domestic industry and support the transition of small-scale illegal cultivators to the legal regime. Foreign investments may alter the economic, social and political determinants of health in transitioning from illegal to legal cannabis market economy.

Assessment of commercial SARS-CoV-2 antibody assays, Jamaica.

BACKGROUND: The performance of the Roche Elecsys® Anti-SARS-CoV-2, Abbott Architect SARS-CoV-2 IgM, Abbott Architect SARS-CoV-2 IgG, Euroimmun SARS-CoV-2 IgA, Euroimmun SARS-CoV-2 IgG ELISA, and Trillium IgG/IgM rapid assays was evaluated in Jamaica. METHODS: Diagnostic sensitivities of the assays were assessed by testing serum samples from SARS-CoV-2 PCR-confirmed persons and diagnostic specificity was assessed by testing serum samples collected during 2018-2019 from healthy persons and from persons with antibodies to a wide range of viral infections. RESULTS: Serum samples collected ≥14 days after onset of symptoms, or an initial SARS-CoV-2 RT-PCR positive test for asymptomatics, showed diagnostic sensitivities ranging from 67.9 to 75.0% when including all possible disease severities and increased to 90.0-95.0% when examining those with moderate to critical disease. Grouping moderate to critical disease showed a significant association with a SARS-CoV-2 antibody positive result for all assays. Diagnostic specificity ranged from 96.7 to 100.0%. For all assays examined, SARS-CoV-2 real-time PCR cycle threshold (Ct) values of the initial nasopharyngeal swab sample testing positive were significantly different for samples testing antibody positive versus negative. CONCLUSIONS: These data from a predominantly African descent Caribbean population show comparable diagnostic sensitivities and specificities for all testing platforms assessed and limited utility of these tests for persons with asymptomatic and mild infections.

Zarit burden interview among caregivers of community-dwelling older adults in a caribbean setting (Jamaica): Reliability and factor structure.

The Zarit Burden Interview has been the most popularly used tool for measuring caregiver burden and with the 60 years and over population in Jamaica and developing countries expected to increase, caregiver burden and its assessment assume increased importance. Establishing the reliability and underlying factor structure of instruments such as the ZBI is critical. This study sought to determine the reliability of the Zarit Burden Interview and to assess its underlying factor structure. The ZBI was administered to 180 caregivers of community dwelling older persons in Jamaica in a nationally representative sample across four geographic health regions in 2016. The factor structure was identified using exploratory factor analysis (EFA) with Varimax rotation. Cronbach's alpha was used to assess internal consistency/reliability of the instrument. The internal consistency/reliability of the ZBI instrument was high (Cronbach's α = 0.859) and the corrected item-total correlations ranged from 0.134 to 0.730. The ZBI mean score was found to be 16.92 ± 12.04. EFA produced a six-factor model comprised of 19 items which explained 48.97% of total variance, and was subsequently reduced to four (37.27% of total variance) via the use of parallel analysis and scrutiny of confidence intervals. The four factors identified were 'personal strain', 'social relations disruption', 'resource strain/imbalance' and 'role intensity'. The ZBI-22 tool is a reliable instrument for evaluating caregiver burden among community dwelling older persons in Jamaica. A four factor model has emerged providing greater insights on the underlying constructs of the ZBI, the most widely used caregiver burden assessment tool.

Caregivers of Older Persons in Jamaica: Characteristics, Burden, and Associated Factors.

OBJECTIVE: The objective of this study was to determine and characterize caregiver burden among caregivers of community-dwelling older persons in Jamaica. METHOD: A nationally representative cross-sectional study was done among persons providing noninstitutional care for a single person (≥60 years). The Zarit Burden Interview (ZBI) and a structured questionnaire were administered to 180 caregivers from four geographic health regions. RESULTS: The ZBI scores ranged from 0 to 56 (median = 15). Independently associated factors were relationship to care recipient and age. Children/grandchildren had higher caregiver burden scores than formally employed caregivers (odds ratio = 2.9: 95% confidence interval: [1.02, 8.34]). Compared with caregivers 35 to 44 years, those aged 45 to 65 were almost 5 times more likely to report higher caregiver burden scores. CONCLUSION: Caregiver burden as identified by the ZBI was low. Age (45-65 years) and being the child/grandchild of the care recipient were independently associated with greater caregiver burden. Interventions to address caregiver burden must embrace strategies that recognize that these factors.
