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.

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.

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.

Use of a simplified clinical audit tool to evaluate hypertension and diabetes management in primary care clinics in Jamaica.

This study evaluates a simple clinical audit tool for assessing quality of care and blood pressure control among persons with hypertension in primary care clinics. A systematic random sampling of persons with diabetes mellitus (DM) and hypertension (HTN) attending five health centers in Kingston, Jamaica, was conducted. A modified Ministry of Health paper-based audit tool captured quality of care and outcome indicators (blood pressure and glycemic control). Additional chart audits were conducted by a physician and nurse to assess reliability. One hundred and forty-nine charts were audited between January and September 2017. One hundred and thirty-eight persons (92.6%) had hypertension (27 men and 111 women); 77 persons (51.7%) had DM (14 men and 63 women). The median age was 64 years old. Approximately two-thirds of persons with HTN and DM had electrolytes, lipid profile, and ECG done within the last year. One-fifth of persons with hypertension (18.5% men and 19.8% women, P = 1.000) had adequate blood pressure control with greater control among persons with HTN only compared to persons with both DM and HTN. Poor glycemic control was recorded for 69% of persons with DM (57% men and 71% women, P = .297). Moderate to substantial inter-rater agreement was observed for quality of care indicators. Our findings confirmed that hypertension and glycemic control are inadequate among persons attending primary care clinics in Jamaica's capital city. Simplified clinical audits can provide important quality of care and outcome indicators without losing the meaningfulness of the data collected.

Central adiposity at diagnosis may reduce prostate cancer-specific mortality in African-Caribbean men with prostate cancer: 10-year follow-up of participants in a case-control study.

PURPOSE: General and central adiposity are associated with the risk of developing prostate cancer (PCa), but the role of these exposures on PCa survival among men of African ancestry are less studied. This study aimed to investigate the association of anthropometry at diagnosis with all-cause and PCa-specific mortality and evaluate whether androgen deprivation therapy (ADT) modulated this risk. METHODS: Associations between body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) at diagnosis and mortality were examined in 242 men with newly diagnosed PCa enrolled between 2005 and 2007 and re-evaluated 10.9 years later. Multi-variable Cox proportional hazard models were used to examine associations of body size variables (using standard WHO cut-points and as continuous variables) with mortality, adjusted for sociodemographic characteristics, Gleason score, smoking, diabetes, primary treatment, and ADT therapy. RESULTS: A total of 139 deaths (all-cause mortality 6.98/100 person-years) occurred (PCa-specific deaths, 56; other causes, 66; causes unknown, 17). In multi-variable analysis BMI, WC and WHR categories at diagnosis were not associated with all-cause mortality even after adjusting for ADT. While WHR (but not BMI or WC) when included as a continuous variable predicted lower PCa-specific mortality (multi-variable adjusted WHR per 0.1 difference: HR, 0.50; 95%CI 0.28, 0.93), the effect disappeared with ADT covariance and excluding deaths within the first 2 years. CONCLUSION: Our study suggests that central adiposity as measured by WHR may improve long-term survival among men of African ancestry. Metabolic studies to understand the mechanism for this association are needed.

Metabolic characteristics of Africans with normal glucose tolerance and elevated 1-hour glucose: insight from the Africans in America study.

INTRODUCTION: Risk of insulin resistance, dyslipidemia, diabetes and cardiac death is increased in Asians and Europeans with normal glucose tolerance (NGT) and 1-hour glucose ≥8.6 mmol/L. As African descent populations often have insulin resistance but a normal lipid profile, the implications for Africans with NGT and glucose ≥8.6 mmol/L (NGT-1-hour-high) are unknown. OBJECTIVE: We performed oral glucose tolerance tests (OGTTs) in 434 African born-blacks living in Washington, DC (male: 66%, age 38±10 years (mean±SD)) and determined in the NGT group if either glucometabolic or lipid profiles varied according to a 1-hour-glucose threshold of 8.6 mmol/L. METHODS: Glucose tolerance category was defined by OGTT criteria. NGT was subdivided into NGT-1-hour-high (glucose ≥8.6 mmol/L) and NGT-1-hour-normal (glucose <8.6 mmol/L). Second OGTT were performed in 27% (119/434) of participants 10±7 days after the first. Matsuda Index and Oral Disposition Index measured insulin resistance and beta-cell function, respectively. Lipid profiles were obtained. Comparisons were by one-way analysis of variance with Bonferonni corrections for multiple comparisons. Duplicate tests were assessed by к-statistic. RESULTS: One-hour-glucose ≥8.6 mmol/L occurred in 17% (47/272) with NGT, 72% (97/134) with pre-diabetes and in 96% (27/28) with diabetes. Both insulin resistance and beta-cell function were worse in NGT-1-hour-high than in NGT-1-hour-normal. Dyslipidemia occurred in both the diabetes and pre-diabetes groups but not in either NGT group. One-hour glucose concentration ≥8.6 mmol/L showed substantial agreement for the two OGTTs (к=0.628). CONCLUSIONS: Although dyslipidemia did not occur in either NGT group, insulin resistance and beta-cell compromise were worse in NGT-1 hour-high. Subdividing the NGT group at a 1-hour glucose threshold of 8.6 mmol/L may stratify risk for diabetes in Africans.

Fortalecimiento de la capacidad institucional para la equidad en la investigación en salud: enseñanzas de América Latina y el Caribe

[EXTRACTO]. Actualmente se presta cada vez más atención a los determinantes políticos, económicos, ambientales y sociales de la salud. Esto ha generado una mayor demanda de investigación para la salud a nivel mundial que incluya a los países de ingresos bajos y medianos, con objeto de alcanzar los objetivos de desarrollo sostenible de las Naciones Unidas. Además del financiamiento, se necesitan suficientes recursos humanos e infraestructura para que estos países lleguen a ser asociados en un plano de igualdad con las instituciones de investigación internacionalmente reconocidas de los países de ingresos altos que establecen las agendas de investigación, y para garantizar que el programa de investigación mundial refleje sus necesidades. Las limitaciones en la capacidad de investigación y las grandes disparidades existentes entre los países de ingresos altos y los de ingresos bajos y medianos en cuanto a su capacidad de producir y usar la investigación para la salud han contribuido a producir una falta de evidencia que permita fundamentar la práctica clínica y orientar las políticas sanitarias regionales y mundiales. Esto ha perpetuado las desigualdades en la salud...

[EXTRACTO]. Existe atualmente um maior reconhecimento dos determinantes políticos, econômicos, ambientais e sociais da saúde. A consequência disso foi um aumento da demanda por pesquisa em saúde global, com participação dos países de baixa e média renda, para cumprir os objetivos de desenvolvimento sustentável das Nações Unidas. Além de financiamento, são necessários recursos humanos e infraestrutura suficientes para que esses países se tornem parceiros em igualdade de condições com instituições de pesquisa internacionalmente reconhecidas em países de alta renda que definem as agendas de pesquisa e cuidam para que o programa global de pesquisa em saúde reflita suas necessidades. A limitada capacidade de pesquisa e as grandes disparidades entre países de alta renda e países de baixa e média renda no tocante à capacidade de produzir e usar pesquisas para a saúde contribuíram para a falta de evidências para informar a prática e orientar as políticas de saúde regionais e globais, o que perpetuou as desigualdades em saúde...

"You Cannot Cure It, Just Control It": Jamaican Adolescents Living With Diabetes.

Although adolescence is considered a difficult time for diabetes management, there is little published qualitative research on adolescent Jamaicans with diabetes. This study investigates the experiences of Jamaican adolescents living with diabetes to determine how their needs can be addressed. Nineteen adolescents participated in two urban and two rural focus groups and were asked to draw pictures representing their experiences. Thematic analysis was used to analyze their narratives, while their drawings were analyzed using a variation of Lauritsen and Mathiasen's (2003) method. Results show that control was the central theme: children felt controlled by diabetes and the people in their lives. Diabetes restricted their activities and imposed a sense of difference. Support from those around them could be both helpful and constricting. Children tried to resist control through disregarding the rules, being secretive, defiant, and manipulating others into allowing nonadherence. They also tried to adhere to the rules, find a balance between following them and engaging in desired activities, and to be positive. Those most positive about living with diabetes did not feel controlled by diabetes or others' understandings of it and, with loved ones' support, had rejected diabetes' negative meanings. Extreme distress was felt by rural children. All children had been noncompliant. Healthcare practitioners and policymakers should provide education in schools to facilitate fair and effective treatment. Mental health specialists should assist children to negotiate stigma and distress. Group sessions with significant others are important for collaborative decisions on enabling support.

Factors associated with elevated blood pressure or hypertension in Afro-Caribbean youth: a cross-sectional study.

BACKGROUND: Although several studies have identified risk factors for high blood pressure (BP), data from Afro-Caribbean populations are limited. Additionally, less is known about how putative risk factors operate in young adults and how social factors influence the risk of high BP. In this study, we estimated the relative risk for elevated BP or hypertension (EBP/HTN), defined as BP ≥ 120/80 mmHg, among young adults with putative cardiovascular disease (CVD) risk factors in Jamaica and evaluated whether relative risks differed by sex. METHODS: Data from 898 young adults, 18-20 years old, were analysed. BP was measured with a mercury sphygmomanometer after participants had been seated for 5 min. Anthropometric measurements were obtained, and glucose, lipids and insulin measured from a fasting venous blood sample. Data on socioeconomic status (SES) were obtained via questionnaire. CVD risk factor status was defined using standard cut-points or the upper quintile of the distribution where the numbers meeting standard cut-points were small. Relative risks were estimated using odds ratios (OR) from logistic regression models. RESULTS: Prevalence of EBP/HTN was 30% among males and 13% among females (p < 0.001 for sex difference). There was evidence for sex interaction in the relationship between EBP/HTN and some of risk factors (obesity and household possessions), therefore we report sex-specific analyses. In multivariable logistic regression models, factors independently associated with EBP/HTN among men were obesity (OR 8.48, 95% CI [2.64-27.2], p < 0.001), and high glucose (OR 2.01, CI [1.20-3.37], p = 0.008), while high HOMA-IR did not achieve statistical significance (OR 2.08, CI [0.94-4.58], p = 0.069). In similar models for women, high triglycerides (OR 1.98, CI [1.03-3.81], p = 0.040) and high HOMA-IR (OR 2.07, CI [1.03-4.12], p = 0.039) were positively associated with EBP/HTN. Lower SES was also associated with higher odds for EBP/HTN (OR 4.63, CI [1.31-16.4], p = 0.017, for moderate vs. high household possessions; OR 2.61, CI [0.70-9.77], p = 0.154 for low vs. high household possessions). Alcohol consumption was associated with lower odds of EBP/HTN among females only; OR 0.41 (CI [0.18-0.90], p = 0.026) for drinking <1 time per week vs. never drinkers, and OR 0.28 (CI [0.11-0.76], p = 0.012) for drinking ≥3 times per week vs. never drinkers. Physical activity was inversely associated with EBP/HTN in both males and females. CONCLUSION: Factors associated with EBP/HTN among Jamaican young adults include obesity, high glucose, high triglycerides and high HOMA-IR, with some significant differences by sex. Among women lower SES was positively associated with EBP/HTN, while moderate alcohol consumption was associated lower odds of EBP/HTN.
