Differences in COVID-19 Vaccination and Experiences among Patients with Hypertension in Colombia and Jamaica during the COVID-19 Pandemic.

During the COVID-19 pandemic, hypertensive patients had increased infection and healthcare disruption in many low- and middle-income countries (LMICs) with limited vaccine access. The objective of this report is to describe COVID-19 experiences and vaccination uptake among hypertensive patients in Colombia and Jamaica. A cross-sectional study of patients with hypertension was conducted in primary care clinics in both countries between 2021 and 2022. Trained interviewers used a telephone-administered questionnaire to assess COVID-19 experiences (infection, vaccination, and healthcare access). A total of 576 patients (68.5% female, mean age: 67.5 years) participated. Health service disruption affecting access to care was low (<10%). Compared to Jamaica, more participants from Colombia reported testing positive for COVID-19, having family members or friends testing positive, losing family members or friends due to COVID-19, and being vaccinated. In logistic regression models, adjusted for age, sex, education, and rural/urban clinic status, fear of COVID-19 (OR 2.7, 95% CI: 1.2-6.1) and residence in Colombia (OR 5.9, 95% CI: 2.4-14.6) were associated with higher vaccination uptake. Disparities in access to COVID-19 testing and diagnosis may have influenced these country differences including fear of COVID-19 and vaccine uptake. Other factors need to be better understood to prepare for future pandemic responses.

Social support and ideal cardiovascular health in urban Jamaica: A cross-sectional study.

Recent studies have suggested that high levels of social support can encourage better health behaviours and result in improved cardiovascular health. In this study we evaluated the association between social support and ideal cardiovascular health among urban Jamaicans. We conducted a cross-sectional study among urban residents in Jamaica's south-east health region. Socio-demographic data and information on cigarette smoking, physical activity, dietary practices, blood pressure, body size, cholesterol, and glucose, were collected by trained personnel. The outcome variable, ideal cardiovascular health, was defined as having optimal levels of ≥5 of these characteristics (ICH-5) according to the American Heart Association definitions. Social support exposure variables included number of friends (network size), number of friends willing to provide loans (instrumental support) and number of friends providing advice (informational support). Principal component analysis was used to create a social support score using these three variables. Survey-weighted logistic regression models were used to evaluate the association between ICH-5 and social support score. Analyses included 841 participants (279 males, 562 females) with mean age of 47.6 ± 18.42 years. ICH-5 prevalence was 26.6% (95%CI 22.3, 31.0) with no significant sex difference (male 27.5%, female 25.7%). In sex-specific, multivariable logistic regression models, social support score, was inversely associated with ICH-5 among males (OR 0.67 [95%CI 0.51, 0.89], p = 0.006) but directly associated among females (OR 1.26 [95%CI 1.04, 1.53], p = 0.020) after adjusting for age and community SES. Living in poorer communities was also significantly associated with higher odds of ICH-5 among males, while living communities with high property value was associated with higher odds of ICH among females. In this study, higher level of social support was associated with better cardiovascular health among women, but poorer cardiovascular health among men in urban Jamaica. Further research should explore these associations and identify appropriate interventions to promote cardiovascular health.

Differences in COVID-19 Vaccination and Experiences among Patients with Hypertension in Colombia and Jamaica during the COVID-19 Pandemic.

Background: COVID-19 vaccination and shielding targeted hypertensive patients in low and middle income countries. We describe the COVID-19 experiences of hypertensive patients in Colombia and Jamaica and discuss factors associated with vaccine acceptance. Methods: A cross-sectional study was conducted between December 2021 and February 2022 in 4 randomly selected primary care clinics in Colombia and 10 primary care clinics in Jamaica. Participants in Colombia were randomly selected from an electronic medical record. In Jamaica consecutive participants were selected on clinic days for non-communicable diseases. Interviewer-administered questionnaires were conducted by telephone. Results: 576 participants were recruited (50% Jamaica; 68.5% female). Jamaica's participants were younger (36% vs 23% <60 years) and had a lower proportion of persons with "more than high school" education (17.2% vs 30.3%, p=0.011). Colombia's participants more commonly tested positive for COVID-19 (24.2% vs 6.3%, p<0.001), had a family member or close friend test positive for COVID-19 (54.5% vs, 21.6%; p<0.001), experienced loss of a family member or friend due to COVID-19 (21.5% vs 7.8%, p<0.001) and had vaccination against COVID-19 (90.6% vs 46.7%, p<0.001). Fear of COVID-19 (AOR 2.71, 95% CI 1.20-6.13) and residence in Colombia (AOR 5.88 (95% CI 2.38-14.56) were associated with COVID-19 vaccination. Disruption in health services affecting prescription of medication or access to doctors was low (<10%) for both countries. Conclusion: Health services disruption was low but COVID-19 experiences such as fear of COVID-19 and vaccine acceptance differed significantly between Colombia and Jamaica. Addressing reasons for these differences are important for future pandemic responses.

Sodium and potassium consumption in Jamaica: National estimates and associated factors from the Jamaica Health and Lifestyle Survey 2016-2017.

This study aimed to estimate dietary sodium and potassium consumption among Jamaicans and evaluate associations with sociodemographic and clinical characteristics. A cross-sectional study was conducted using data from the Jamaica Health and Lifestyle Survey 2016-2017. Participants were noninstitutionalized Jamaicans aged ≥15 years. Trained staff collected sociodemographic and health data via interviewer-administered questionnaires and spot urine samples. The Pan American Health Organization formula was used to estimate 24-hour urine sodium and potassium excretion. High sodium level was defined as ≥2000 mg/day, and low potassium levels as <3510 mg/day (World Health Organization criteria). Associations between these outcomes and sociodemographic and clinical characteristics were explored using multivariable ANOVA models using log-transformed 24-hour urine sodium and potassium as outcome variables. Analyses included 1009 participants (368 males, 641 females; mean age 48.5 years). The mean sodium excretion was 3582 mg/day (males 3943 mg/day, females 3245 mg/day, P < .001). The mean potassium excretion was 2052 mg/day (males, 2210 mg/day; females, 1904 mg/day; P = .001). The prevalence of high sodium consumption was 66.6% (males 72.8%, females 60.7%, P < .001) and that of low potassium intake was 88.8% (85.1% males, 92.3% females, P < .001). Sodium consumption was inversely associated with older age, higher education, and low glomerular filtration rate but was directly associated with being male, current smoking, and obesity. Overall, males had higher sodium consumption than women, with the effect being larger among hypertensive men. Women with hypertension had lower sodium consumption than nonhypertensive women; however, hypertensive men had higher sodium consumption than nonhypertensive men. Potassium consumption was higher among men, persons with obesity, and those with high total cholesterol but was lower among men with "more than high school" education compared to men with "less than high school" education. We conclude that most Jamaican adults have diets high in sodium and low in potassium. In this study, sodium consumption was directly associated with male sex, obesity, and current smoking but was inversely associated with older age and higher education. High potassium consumption was associated with obesity and high cholesterol levels. These associations should be further explored in longitudinal studies and population-based strategies should be developed to address these cardiovascular risk factors.

Maternal feeding styles in infancy predict child body mass index z-scores at 72 months: findings from a cohort of Jamaican children.

Objective: To explore whether maternal feeding styles at 12 months predict child Body Mass Index (BMI) z-scores at 72 months and evaluate whether BMI z-scores at 18 months mediates the association. Methods: Data from 239 mother-child pairs participating in a parenting intervention were analyzed. Feeding information was ascertained at 12 months by questionnaire with feeding styles identified using factor analysis. Children's weight and length/height were measured at 18 and 72 months and BMI z-scores computed. Maternal sociodemographic data, depressive symptoms and language skills were obtained by questionnaire. Multilevel linear regression analysis was used to examine whether feeding styles predicted 72 month BMI z-scores. Complete case analysis was conducted and multiple imputation used to treat missing values of explanatory and outcome variables at 18 and 72 months. Mediational analysis was performed to assess the indirect effects of feeding styles on 72 month BMI z-scores via 18 month BMI z-scores. Results: Restrictive feeding at age 12 months predicted higher 72 month BMI z-scores in both complete case analysis [ß (95%CI): 0.19 (0.02, 0.37)] and multiple imputation [ß (95%CI): 0.20 (0.02, 0.39)]. Uninvolved, forceful, indulgent and responsive feeding styles were not significant predictors of 72 month BMI z-scores. A significant indirect effect was observed between restrictive feeding and child BMI z-scores at 72 months via 18 month BMI z-scores [ß (95% CI) 0.12 (0.03, 0.22)]. Conclusion: Restrictive feeding at 12 months was associated with higher BMI z-scores at 72 months and appeared to be mediated by BMI z-scores at 18 months.

Community stressors (violence, victimization, and neighborhood disorder) with cardiometabolic outcomes in urban Jamaica.

Background: Despite limited data on neighborhood factors and health risk in Caribbean populations, previous analyses from Jamaica have shown that neighborhood and home disorder were associated with lower physical activity and higher cumulative biological risk among women, while poorer neighborhood infrastructure was associated with higher overweight/obesity among men. Design: Cross-sectional survey design. Objectives: In this study, we explored whether community stressors, as measured by community violence, victimization and neighborhood disorder scores, were associated with cardiometabolic outcomes (obesity, diabetes, hypertension and high cholesterol) in urban Jamaican communities. Sex-specific Poisson regression models were used to estimate prevalence ratios (PR) for these associations, adjusting for age, education, diet, physical activity and smoking. Participants: Of the 849 participants (M = 282; F = 567), mean age was 48 ± 18.5 years and most had at least a high school education. Men were more likely to be current smokers (29.4 vs. 10.6%) and adequately physically active (53.2 vs. 42.0%); more women were obese (46.0 vs. 19.0%), more likely to have hypertension (52.9 vs. 45.4%) and had high cholesterol (34.2 vs. 21.6%) (all p < 0.05). Results: We observed significant associations only for those in the middle tertile of neighborhood disorder with prevalence of higher cholesterol [PR:1.72 (1.20 to 2.47)] in women and lower prevalence of obesity [PR:0.24 (0.10 to 0.53)] in men. Conclusion: Results suggest that higher, but not the highest level of neighborhood disorder was associated with higher cholesterol levels in women and lower obesity in men. Future work will explore additional approaches to measuring neighborhood characteristics in Jamaica and the mechanisms that may underlie any relationships that are identified.

Acceptability and use of waist-worn physical activity monitors in Jamaican adolescents: lessons from the field.

OBJECTIVE: We report our experience with a validated waist-worn activity monitor in Jamaican adolescents attending urban high schools. Seventy-nine adolescents from the Global Diet and Activity Research (GDAR) study, recruited from 5 urban Jamaican high schools (two coeducational (n = 37), two all-female schools (n = 32) and one all-boys school (n = 10)) were asked to wear Actigraph wGT3X-BT accelerometers for 7 days (24-h), removing the device only when bathing or swimming. They also logged wake up and bed times in an activity diary. Accelerometry was considered valid if at least 4 days with ≥ 10-h monitor wear were recorded. Validity was compared by adolescent demographic and school characteristics. We also reviewed the students' written feedback on objective physical activity measurement. RESULTS: Participants, 80.5% female, had a mean age of 15.5 ± 0.8 years with 60% attending schools in low-income communities. Accelerometer return rates were > 98% with 84% providing valid data. Validity did not vary by age group, sex and school setting. While participants were excited about participating in the accelerometer sub-study, commonly reported challenges included monitor discomfort during sleep and maintaining the study diary. Objective measurement of physical activity using 24-h waist-worn accelerometers is feasible and acceptable in Jamaican adolescents.

Vitamin D Deficiency at Diagnosis Increases All-Cause and Prostate Cancer-specific Mortality in Jamaican Men.

BACKGROUND: 25 hydroxyvitamin D [25(OH)D] and serum calcium have been associated with incident prostate cancer (PCa). However, there is limited data on whether these metabolites predict survival in men of African descent, a population disproportionately affected by PCa. We studied the relationship of 25(OH)D at PCa diagnosis with all-cause and cancer-specific mortality among Jamaican men and examined whether serum calcium modified any associations. METHODS: Serum 25(OH)D from 152 Jamaican men with incident PCa within the Prostate Cancer Risk Evaluation (PROSCARE) study were re-evaluated approximately 11 years after enrollment. 25(OH)D analyses were stratified using the using Holick criteria. PCa-specific and all-cause mortality were examined in Kaplan-Meier survival curves and Cox regression models adjusted for age, body mass index (BMI), smoking and Gleason score. Restricted cubic splines evaluated nonlinear associations. Serum calcium was assessed as an effect modifier of the association between 25(OH)D and mortality. RESULTS: Of cases with available 25(OH)D, 64 men with PCa survived, 38 deaths were PCa specific and 36 died of other causes. At baseline, 9.9% of cases were vitamin D deficient and 61.2% were vitamin D sufficient. Compared to 25(OH)D sufficient men, those with 25(OH)D <20.0 ng/mL concentrations were associated with higher PCa-specific mortality (adjusted HR, 4.95; 95% CI, 1.68, 14.63, P = .004) and all-cause mortality (adjusted HR, 2.40; 95%CI, 1.33, 4. 32, P = .003). Serum calcium was not associated with survival and did not modify any associations with 25(OH)D. CONCLUSIONS: 25(OH)D deficiency at PCa diagnosis predicted decreased survival for overall and PCa-specific cancer in Caribbean men of African ancestry.

Health-related quality of life in long-term Caribbean prostate cancer survivors: comparisons with prostate cancer-free men.

PURPOSE: Prostate cancer (PCa) and its treatment can impact health-related quality of life (HRQoL). There are few studies of HRQoL in long-term PCa survivors of African ancestry from low- and middle-income countries. We examined the effect of PCa treatment on HRQoL of Jamaican PCa survivors compared with cancer-free controls and explored the effect of demographic and clinical factors on these outcomes. METHODS: PCa survivors (n = 64) treated with and without ADT along with PCa-free controls (n = 88) from a case-control study of 10 years post enrolment. HRQoL was measured using the European Organisation for Research and Treatment of Cancer Quality of Life (EORTC-QLQ-C30). Effects of demographic and clinical variables on HRQoL on PCa and type of therapy were evaluated in multivariable linear regression models. RESULTS: HRQoL of PCa survivors (overall and by treatment group) indicated a high quality of life, comparable to PCa-free men. However, ADT-treated survivors had lower physical functioning that was of small clinical relevance compared with those not on ADT. Symptom burden scores of PCa survivors and controls were similar excluding fatigue and dyspnoea which were highest in men on ADT and controls. In multivariable models, PCa was not an important determinant of overall HRQoL, functioning or symptom burdens. Underlying medical conditions and marital status were the main contributors to HRQoL in PCa survivors. CONCLUSION: PCa cancer status was not an independent determinant of long-term HRQoL in Jamaican men. Interventions addressing social factors and comorbid illnesses could improve HRQOL in long-term PCa survivors.

Socioeconomic and gendered inequities in travel behaviour in Africa: Mixed-method systematic review and meta-ethnography.

Travel has individual, societal and planetary health implications. We explored socioeconomic and gendered differences in travel behaviour in Africa, to develop an understanding of travel-related inequity. We conducted a mixed-methods systematic review (PROSPERO CRD42019124802). In 2019, we searched MEDLINE, TRID, SCOPUS, Web of Science, LILACS, SciELO, Global Health, Africa Index Medicus, CINAHL and MediCarib for studies examining travel behaviour by socioeconomic status and gender in Africa. We appraised study quality using Critical Appraisal Skills Programme checklists. We synthesised qualitative data using meta-ethnography, followed by a narrative synthesis of quantitative data, and integrated qualitative and quantitative strands using pattern matching principles. We retrieved 103 studies (20 qualitative, 24 mixed-methods, 59 quantitative). From the meta-ethnography, we observed that travel is: intertwined with social mobility; necessary to access resources; associated with cost and safety barriers; typified by long distances and slow modes; and dictated by gendered social expectations. We also observed that: motorised transport is needed in cities; walking is an unsafe, 'captive' mode; and urban and transport planning are uncoordinated. From these observations, we derived hypothesised patterns that were tested using the quantitative data, and found support for these overall. In lower socioeconomic individuals, travel inequity entailed reliance on walking and paratransit (informal public transport), being unable to afford travel, travelling less overall, and travelling long distances in hazardous conditions. In women and girls, travel inequity entailed reliance on walking and lack of access to private vehicles, risk of personal violence, societally-imposed travel constraints, and household duties shaping travel. Limitations included lack of analytical rigour in qualitative studies and a preponderance of cross-sectional quantitative studies (offering a static view of an evolving process). Overall, we found that travel inequity in Africa perpetuates socioeconomic and gendered disadvantage. Proposed solutions focus on improving the safety, efficiency and affordability of public transport and walking.

The Jamaica Salt Consumption Study Protocol: Sodium Intake; Sodium Content in Restaurant Foods; Knowledge, Attitudes, and Practices; Spot Urine Sodium Validation.

Background: Excess dietary salt consumption is a major contributor to hypertension and cardiovascular disease. Public education programs on the dangers of high salt intake, and population level interventions to reduce the salt content in foods are possible strategies to address this problem. In Jamaica, there are limited data on the levels of salt consumption and the population's knowledge and practices with regards to salt consumption. This study therefore aims to obtain baseline data on salt consumption, salt content in foods sold in restaurants, and evaluate knowledge, attitudes, and practices of Jamaicans regarding salt consumption. Methods: The study is divided into four components. Component 1 will be a secondary analysis of data on urinary sodium from spot urine samples collected as part of a national survey, the Jamaica Health and Lifestyle Survey 2016-2017. Component 2 will be a survey of chain and non-chain restaurants in Jamaica, to estimate the sodium content of foods sold in restaurants. Component 3 is another national survey, this time on a sample 1,200 individuals to obtain data on knowledge, attitudes and practices regarding salt consumption and estimation of urinary sodium excretion. Component 4 is a validation study to assess the level of agreement between spot urine sodium estimates and 24-hour urinary sodium from 120 individuals from Component 3. Discussion: This study will provide important baseline data on salt consumption in Jamaica and will fulfil the first components of the World Health Organization SHAKE Technical Package for Salt Reduction. The findings will serve as a guide to Jamaica's Ministry of Health and Wellness in the development of a national salt reduction program. Findings will also inform interventions to promote individual and population level sodium reduction strategies as the country seeks to achieve the national target of a 30% reduction in salt consumption by 2025.

An Evaluation of Regional Cardiovascular Disease and Cancer Research Needs Using Conference Abstracts.

Background: Despite cardiovascular diseases and cancer being the leading causes of premature mortality in the Caribbean region, there is limited local research available to guide a comprehensive response to this epidemic. Objective: To evaluate cardiovascular disease and cancer research in the Caribbean using abstracts presented at the Caribbean Public Health Agency's (CARPHA) meeting - the longest running annual research conference in the region. Method: Study data (population, intervention/exposure, comparison and outcome) were extracted from abstracts published for the 2006 to 2018 meetings. Additionally, institutional affiliation and geographic location of the first author, countries involved, sample size, study design and use of specialized testing/biomarkers were also extracted. Data were analysed using STATA version 14. Findings: A total of 1,512 abstracts, 728 posters and 784 oral presentations were reviewed. Research on cancer and cardiovascular disease comprised approximately 15% of all abstracts published annually over the review period. Most of the cardiovascular disease studies had cross sectional or survey designs (46%), with very few laboratory-based studies (<2%) and no intervention studies/clinical trials. For cancer research, 30% were cross-sectional studies/audits, 11% were case control studies, 5% were lab based and there were no clinical trials. Almost a quarter of the cardiovascular disease / cancer abstracts over the period originated from Trinidad and Tobago (26%), with Jamaica and Barbados contributing 18% and 15% respectively. Conclusion: These finding highlight the need for additional studies that can provide evidence for interventions and policy to address the region's high cardiovascular disease and cancer burden. A Regional Centre of Research Excellence could support capacity development to facilitate this process.

Adolescent Levers for a Diet and Physical Activity Intervention Across Socioecological Levels in Kenya, South Africa, Cameroon, and Jamaica: Mixed Methods Study Protocol.

BACKGROUND: The increasing burden of noncommunicable diseases that are prevalent in low- and middle-income countries (LMICs) is largely attributed to modifiable behavioral risk factors such as unhealthy diets and insufficient physical activity (PA). The adolescent stage, defined as 10 to 24 years of age, is an important formative phase of life and offers an opportunity to reduce the risk of noncommunicable diseases across the life course and for future generations. OBJECTIVE: The aim of this paper is to describe a protocol for a study using a convergent mixed methods design to explore exposures in the household, neighborhood, school, and the journey from home to school that may influence diet and PA behaviors in adolescents from LMICs. METHODS: Male and female adolescents (n≥150) aged between 13 and 24 years will be recruited from selected high schools or households in project site countries to ensure the socioeconomic diversity of perspectives and experiences at the individual, home, and neighborhood levels. The project will be conducted at 5 sites in 4 countries: Kenya, Cameroon, Jamaica, and South Africa (Cape Town and Johannesburg). Data on anthropometric measures, food intake, and PA knowledge and behavior will be collected using self-report questionnaires. In addition, a small number of learners (n=30-45) from each site will be selected as citizen scientists to capture data (photographs, audio notes, text, and geolocations) on their lived experiences in relation to food and PA in their homes, the journey to and from school, and the school and neighborhood environments using a mobile app, and for objective PA measurements. In-depth interviews will be conducted with the citizen scientists and their caregivers to explore household experiences and determinants of food intake and foodways, as well as the PA of household members. RESULTS: The study described in this protocol paper was primarily funded through a UK National Institute for Health Research grant in 2017 and approved by the relevant institutional ethics review boards in the country sites (South Africa, Cameroun, and Jamaica in 2019, and Kenya in 2020). As of December 23, 2020, we had completed data collection from adolescents (n≥150) in all the country sites, except Kenya, and data collection for the subgroup (n=30-45) is ongoing. Data analysis is ongoing and the output of findings from the study described in this protocol is expected to be published by 2022. CONCLUSIONS: This project protocol contributes to research that focuses on adolescents and the socioecological determinants of food intake and PA in LMIC settings. It includes innovative methodologies to interrogate and map the contexts of these determinants and will generate much-needed data to understand the multilevel system of factors that can be leveraged through upstream and downstream strategies and interventions to improve health outcomes.

Maternal characteristics influence infant feeding styles in Caribbean women.

OBJECTIVE: To examine associations between maternal characteristics and feeding styles in Caribbean mothers. DESIGN: Participants were mother-child pairs enrolled in a cluster randomised trial of a parenting intervention in three Caribbean islands. Maternal characteristics were obtained by questionnaires when infants were 6-8 weeks old. Items adapted from the Toddler Feeding Behaviour Questionnaire were used to assess infant feeding styles at the age of 1 year. Feeding styles were identified using factor analysis and associations with maternal characteristics assessed using multilevel linear regression. SETTING: Health clinics in St. Lucia (n 9), Antigua (n 10) and Jamaica (n 20). PARTICIPANTS: A total of 405 mother-child pairs from the larger trial. RESULTS: Maternal depressive symptoms were associated with uninvolved (ß = 0·38, 95 % CI (0·14, 0·62)), restrictive (ß = 0·44, 95 % CI (0·19, 0·69)) and forceful (ß = 0·31, 95 % CI (0·06, 0·57)) feeding and inversely associated with responsive feeding (ß = -0·30, 95 % CI (-0·56, -0·05)). Maternal vocabulary was inversely associated with uninvolved (ß = -0·31, 95 % CI (-0·57, -0·06)), restrictive (ß = -0·30, 95 % CI (-0·56, -0·04)), indulgent (ß = -0·47, 95 % CI (-0·73, -0·21)) and forceful (ß = -0·54, 95 % CI (-0·81, -0·28)) feeding. Indulgent feeding was negatively associated with socio-economic status (ß = -0·27, 95 % CI (-0·53, -0·00)) and was lower among mothers ≥35 years (ß = -0·32, 95 % CI (-0·62, -0·02)). Breast-feeding at 1 year was associated with forceful feeding (ß = 0·41, 95 % CI (0·21, 0·61)). No significant associations were found between maternal education, BMI, occupation and feeding styles. CONCLUSION: Services to identify and assist mothers with depressive symptoms may benefit infant feeding style. Interventions to promote responsive feeding may be important for less educated, younger and socio-economically disadvantaged mothers.

A cross-sectional analysis of investigator needs for non-communicable disease research at the University of the West Indies, Mona.

OBJECTIVE: To describe the needs of academic staff conducting non-communicable disease (NCD) research at the University of the West Indies, Mona Campus in Jamaica. METHODS: Utilizing a cross-sectional design an online survey was created using the research electronic data capture application (REDCap); it was disseminated via email to 708 academic staff members in the Faculties of Medical Sciences and Science & Technology between September and November 2018. Participants were asked to indicate their level of access to expertise, training and equipment for conducting research. Descriptive analysis was conducted using STATA version 14. RESULTS: Most respondents were women (74.2%), predominantly scientists (33.1%) or specialist physicians (22.6%). Less than 2/3 of respondents reported publishing research findings in peer reviewed journals, with a quarter not disseminating their research findings in any medium. Resources for field research/data collection, epidemiological methods and principles, and data management/data analysis were generally available. However, there was limited access to training, expertise and equipment in emerging techniques for NCD research such as metabolomics, bioinformatics/analysis of large-scale data sets and health economics. Additional challenges included limited access to financing for research, inadequate workspace and poor administrative support for conducting research. CONCLUSIONS: There is a need for more local research seed funding, stronger administrative support for researchers, and opportunities for training in cutting edge NCD research techniques. Jamaican researchers could benefit from being part of a regional research centre of excellence with critical research skills and equipment that builds research networks and strengthens the NCD research response.

[RESUMEN]. Objetivo. Describir las necesidades del personal académico que investiga las enfermedades no transmisibles (ENT) en el Campus de Mona de la Universidad de las Indias Occidentales, en Jamaica. Métodos. Mediante un diseño transversal, se elaboró una encuesta en línea con RedCap, una aplicación para la captura de datos electrónicos para la investigación, y se divulgó por correo electrónico a los 708 miembros del personal académico de las Facultades de Ciencias Médicas y Ciencia y Tecnología entre septiembre y noviembre del 2018. Se pidió a los participantes que indicaran su nivel de acceso a conocimientos, capacitación y equipo para llevar a cabo investigaciones. El análisis descriptivo se realizó con STATA, versión 14. Resultados. La mayoría de los entrevistados fueron mujeres (74,2%), predominantemente científicas (33,1%) o médicas especialistas (22,6%). Menos de dos terceras partes de los entrevistados informó que publicaban los resultados de sus investigaciones en revistas arbitradas y una cuarta parte declaró que no divulgaba los resultados de sus investigaciones en ningún medio. Por lo general, tenían a su disposición recursos para la investigación de campo o la recopilación de datos, métodos y principios epidemiológicos, así como para la gestión y el análisis de datos. Sin embargo, tenían poco acceso a conocimientos, capacitación y equipo en las técnicas emergentes para la investigación sobre ENT como la metabolómica, la bioinformática o el análisis de conjuntos de datos a gran escala y economía de la salud. Otros retos incluyeron poco acceso al financiamiento para la investigación, espacios de trabajo inadecuados y un apoyo administrativo deficiente para investigar. Conclusiones. Se necesita más capital inicial destinado a la investigación local, un mayor respaldo administrativo a los investigadores y oportunidades de capacitación en las técnicas más recientes de investigación de ENT. Los investigadores jamaiquinos podrían sacar provecho de formar parte de un centro regional de excelencia para la investigación con el equipo y las capacidades de investigación fundamentales para contribuir a la formación de redes de investigación y fortalecer la respuesta investigadora a las ENT.

The Cancer Prevention Project of Philadelphia: preliminary findings examining diversity among the African diaspora.

Objective: Cancer mortality inequity among persons of African Ancestry is remarkable. Yet, Black inclusion in cancer biology research is sorely lacking and warrants urgent attention. Epidemiologic research linking African Ancestry and the African Diaspora to disease susceptibility and outcomes is critical for understanding the significant and troubling health disparities among Blacks. Therefore, in a cohort of diverse Blacks, this study examined differences in genetic ancestry informative markers (AIMs) in the DNA repair pathway and the cancer related biomarker 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL).Methods: Participants completed a questionnaire and provided bio-specimens. AIMs in or around DNA repair pathway genes were analyzed to assess differences in minor allele frequency (MAF) across the 3 ethnic subgroups. NNAL concentration in urine was measured among current smokers.Results: To date the cohort includes 852 participants, 88.3% being Black. Of the 752 Blacks, 51.3% were US-born, 27.8% were Caribbean-born, and 19.6% were Africa-born. Current and former smokers represented 14.9% and 10.0%, respectively. US-born Blacks were more likely to be smokers and poor metabolizers of NNAL. Two-way hierarchical clustering revealed MAF of AIMs differed across the 3 ethnic subgroups.Conclusion: Our findings are consistent with the emerging literature demonstrating Black heterogeneity underscoring African Ancestry genetic subgroup differences - specifically relevant to cancer. Further investigations, with data harmonization and sharing, are urgently needed to begin to map African Ancestry cancer biomarkers as well as race, and race by place\region comparative biomarkers to inform cancer prevention and treatment in the era of precision medicine.

A cross-sectional analysis of investigator needs for non-communicable disease research at the University of the West Indies, Mona / Análisis transversal de las necesidades de los investigadores de las enfermedades no transmisibles en la Universidad de las Indias Occidentales en Mona / Uma análise transversal das carências dos pesquisadores envolvidos em pesquisa de doenças não transmissíveis na Universidade das Índias Ocidentais, Mona

ABSTRACT Objective. To describe the needs of academic staff conducting non-communicable disease (NCD) research at the University of the West Indies, Mona Campus in Jamaica. Methods. Utilizing a cross-sectional design an online survey was created using the research electronic data capture application (REDCap); it was disseminated via email to 708 academic staff members in the Faculties of Medical Sciences and Science & Technology between September and November 2018. Participants were asked to indicate their level of access to expertise, training and equipment for conducting research. Descriptive analysis was conducted using STATA version 14. Results. Most respondents were women (74.2%), predominantly scientists (33.1%) or specialist physicians (22.6%). Less than 2/3 of respondents reported publishing research findings in peer reviewed journals, with a quarter not disseminating their research findings in any medium. Resources for field research/data collection, epidemiological methods and principles, and data management/data analysis were generally available. However, there was limited access to training, expertise and equipment in emerging techniques for NCD research such as metabolomics, bioinformatics/analysis of large-scale data sets and health economics. Additional challenges included limited access to financing for research, inadequate workspace and poor administrative support for conducting research. Conclusions. There is a need for more local research seed funding, stronger administrative support for researchers, and opportunities for training in cutting edge NCD research techniques. Jamaican researchers could benefit from being part of a regional research centre of excellence with critical research skills and equipment that builds research networks and strengthens the NCD research response.

RESUMEN Objetivo. Describir las necesidades del personal académico que investiga las enfermedades no transmisibles (ENT) en el Campus de Mona de la Universidad de las Indias Occidentales, en Jamaica. Métodos. Mediante un diseño transversal, se elaboró una encuesta en línea con RedCap, una aplicación para la captura de datos electrónicos para la investigación, y se divulgó por correo electrónico a los 708 miembros del personal académico de las Facultades de Ciencias Médicas y Ciencia y Tecnología entre septiembre y noviembre del 2018. Se pidió a los participantes que indicaran su nivel de acceso a conocimientos, capacitación y equipo para llevar a cabo investigaciones. El análisis descriptivo se realizó con STATA, versión 14. Resultados. La mayoría de los entrevistados fueron mujeres (74,2%), predominantemente científicas (33,1%) o médicas especialistas (22,6%). Menos de dos terceras partes de los entrevistados informó que publicaban los resultados de sus investigaciones en revistas arbitradas y una cuarta parte declaró que no divulgaba los resultados de sus investigaciones en ningún medio. Por lo general, tenían a su disposición recursos para la investigación de campo o la recopilación de datos, métodos y principios epidemiológicos, así como para la gestión y el análisis de datos. Sin embargo, tenían poco acceso a conocimientos, capacitación y equipo en las técnicas emergentes para la investigación sobre ENT como la metabolómica, la bioinformática o el análisis de conjuntos de datos a gran escala y economía de la salud. Otros retos incluyeron poco acceso al financiamiento para la investigación, espacios de trabajo inadecuados y un apoyo administrativo deficiente para investigar. Conclusiones. Se necesita más capital inicial destinado a la investigación local, un mayor respaldo administrativo a los investigadores y oportunidades de capacitación en las técnicas más recientes de investigación de ENT. Los investigadores jamaiquinos podrían sacar provecho de formar parte de un centro regional de excelencia para la investigación con el equipo y las capacidades de investigación fundamentales para contribuir a la formación de redes de investigación y fortalecer la respuesta investigadora a las ENT.

Ideal cardiovascular health in urban Jamaica: prevalence estimates and relationship to community property value, household assets and educational attainment: a cross-sectional study.

OBJECTIVE: Ideal cardiovascular health (ICH) is associated with greater longevity and reduced morbidity, but no research on ICH has been conducted in Jamaica. We aimed to estimate the prevalence of ICH in urban Jamaica and to evaluate associations between ICH and community, household, and individual socioeconomic status (SES). DESIGN: Cross-sectional study. SETTING: Urban communities in Jamaica. PARTICIPANTS: 360 men and 665 women who were urban residents aged ≥20 years from a national survey, the Jamaica Health and Lifestyle Survey 2016-2017. EXPOSURES: Community SES, using median land values (MLV); household SES, using number of household assets; and individual SES, using education level. PRIMARY OUTCOME: The main outcome variable was ICH, defined as having five or more of seven ICH characteristics (ICH-5): current non-smoking, healthy diet, moderate physical activity, normal body mass index, normal blood pressure, normal glucose and normal cholesterol. Prevalence was estimated using weighted survey design and logistic regression models were used to evaluate associations. RESULTS: The prevalence of overall ICH (seven characteristics) was 0.51%, while the prevalence of ICH-5 was 22.9% (male 24.5%, female 21.5%, p=0.447). In sex-specific multivariable models adjusted for age, education, and household assets, men in the lower tertiles of community MLV had lower odds of ICH-5 compared with men in the upper tertile (lowest tertile: OR 0.33, 95% CI 0.12 to 0.91, p=0.032; middle tertile: OR 0.46, 95% CI 0.20 to 1.04, p=0.062). Women from communities in the lower and middle tertiles of MLV also had lower odds of ICH-5, but the association was not statistically significant. Educational attainment was inversely associated with ICH-5 among men and positively associated among women. CONCLUSION: Living in poorer communities was associated with lower odds of ICH-5 among men in Jamaica. The association between education level and ICH-5 differed in men and women.

The global diet and activity research (GDAR) network: a global public health partnership to address upstream NCD risk factors in urban low and middle-income contexts.

BACKGROUND: Non-communicable diseases (NCDs) are the leading cause of death globally. While upstream approaches to tackle NCD risk factors of poor quality diets and physical inactivity have been trialled in high income countries (HICs), there is little evidence from low and middle-income countries (LMICs) that bear a disproportionate NCD burden. Sub-Saharan Africa and the Caribbean are therefore the focus regions for a novel global health partnership to address upstream determinants of NCDs. PARTNERSHIP: The Global Diet and Activity research Network (GDAR Network) was formed in July 2017 with funding from the UK National Institute for Health Research (NIHR) Global Health Research Units and Groups Programme. We describe the GDAR Network as a case example and a potential model for research generation and capacity strengthening for others committed to addressing the upstream determinants of NCDs in LMICs. We highlight the dual equity targets of research generation and capacity strengthening in the description of the four work packages. The work packages focus on learning from the past through identifying evidence and policy gaps and priorities, understanding the present through adolescent lived experiences of healthy eating and physical activity, and co-designing future interventions with non-academic stakeholders. CONCLUSION: We present five lessons learned to date from the GDAR Network activities that can benefit other global health research partnerships. We close with a summary of the GDAR Network contribution to cultivating sustainable capacity strengthening and cutting-edge policy-relevant research as a beacon to exemplify the need for such collaborative groups.
