Abstract
ETHNOPHARMACOLOGICAL RELEVANCE A survey was undertaken in Jamaica to document medicinal plants frequently used in the treatment or prophylaxis of illness and trends in their use, following the methodology established by the TRAMIL network. TRAMIL, a Caribbean-wide applied research programme, scientifically evaluates and documents the efficacy and safety of medicinal plant remedies used for primary health care. Initial results from this survey, on an aspect of safety, focusing on the concomitant use and prevalence of medicinal plant use in combination with pharmaceutical drugs in Jamaica, were published in an earlier paper in 2011. This paper now reports survey results on the ethnobotanical use of medicinal plants by Jamaicans. MATERIALS AND METHODS A survey using a structured and modified TRAMIL questionnaire was administered to 407 adults selected randomly from systematically selected households within randomly selected clusters. The clusters were selected from each of the three areas that were purposefully selected. KEY FINDINGS Respondents identified their use of 107 botanically identified medicinal plants distributed in 51 plant families to treat illnesses or maintain health in the previous twelve months. Fourteen plants, with significant use equal to or greater than 20% for a specified health issue were shortlisted, representing Jamaica׳s first submission to the TRAMIL database. Andrographis paniculata (Burm. f.) Nees (Rice Bitters) was reported as a plant remedy with significant use for the first time in a TRAMIL survey. Informant consensus factor (ICF) values were high for a number of health issues such as mental health (nerves, insomnia, etc.), respiratory system (cold/flu/cough etc.) and for health maintenance with tonics (washout and blood cleanse), indicating strong cultural coherence in medicinal plant selection for these categories. Forty two per cent (113/270) of medicinal plant users utilised mixtures, combining more than one plant. Leaf material was the most commonly used plant part (69%), with fresh material (98%) most commonly prepared as a tea for internal use by decoction (87%). The majority of medicinal plant respondents sourced plants from their backyards (75%) and cited grandmothers (33%) and mothers (32%) as their main sources of information. Jamaicans reported limited use of complementary and alternative medicine (CAM), supporting the assertion that a significant number of citizens in developing countries continue to rely on the use of medicinal plants for primary healthcare. CONCLUSIONS Medicinal plant use continues to play an important role in primary healthcare in Jamaica. Fourteen plant remedies with significant use are reported, five previously reported elsewhere and recommended (REC) for the same health condition. Eight plant remedies, including one Jamaican endemic, are reported for different health issues for the first time to TRAMIL and will be investigated (INV) for the new health conditions, together with one plant remedy reported for the first time. This latest survey will be followed by literature reviews, appropriate laboratory screens (TRIG) and community outreach activities (TRADIF) in Jamaica.

Abstract
OBJECTIVE To determine the best predictor of mortality risk in very low birth weight (VLBW) infants in resource limited settings. METHODS The Clinical Risk Index for Babies (CRIB) II score and the simplified age-weight-sex (SAWS) score for all VLBW infants born during the period January 2005 to June 2006 at the University Hospital of the West Indies were retrospectively calculated. The respective ability of each score, birth weight, and calculated or assessed gestational age to predict mortality was quantified using the area under receiver operating curves. RESULTS Fifty two (48%) males and 57 (52%) females were entered into the study, out of which 58 (53%) infants died. The CRIB II score was found to be a better predictor of mortality (p = 0.02) when compared with calculated gestational age but had similar predictive power when compared with assessed gestational age. The SAWS score was found to have equal predictive value of mortality (p = 0.1) as the CRIB II score, however it was a better predictor of mortality than calculated gestational age (p = 0.002) but had no predictive advantage over assessed gestational age. Birth weight however, proved to be the best predictor of mortality (p < 0.01) with an area under the curve of 0.91 (standard error 0.03; 95% confidence interval 0.85-0.96). CONCLUSION In resource poor settings where mortality of VLBW infants is high there may be no benefit in the addition of other variables to birth weight in predicting outcome.

Abstract
OBJECTIVE To estimate the prevalence and correlates of overweight and obesity among children six to ten years old in the North-East Health Region (NEHR) ofJamaica. METHODS Weights and heights were measured in a representative sample of 5710 children between the ages of six and ten years in 34 schools between October 2008 and March 2009. Overweight and obesity were defined as body mass index (BMI) Z-score > 1SD and >2SD, respectively based on the World Health Organization (WHO)-endorsed age and gender-specific growth standards for children. Point prevalence estimates of overweight and obesity were calculated. Odds ratios (OR) and 95% confidence intervals (CI) were used to estimate associations between overweight and obesity and age, gender and school location. RESULTS Overweight and obesity prevalence among children six to ten years old in NEHR, Jamaica, was 10.6% and 7.1%, respectively. Overweight (OR = 1.11, 95% CI: 1.04, 1.18) and obesity (OR = 1.17, 95% CI: 1.08, 1.26) prevalence increased significantly with age. Overweight (OR = 1.51, 95% CI: 1.27, 1.80) and obesity (OR = 1.36, 95% CI: 1.11, 1.67) prevalence was significantly higher among girls than boys. Children attending rural-public schools had less risk of being overweight (OR = 0.57, 95% CI: 0.46, 0.70) and obese (OR = 0.35, 95% CI: 0.28, 0.44) when compared with urban-public schools and private schools. Both overweight (OR = 2.11, 95% CI: 1.60, 2.78) and obesity (OR = 1.68, 95% CI: 1.24, 2.28) were significantly more common among children attending private schools. After adjusting for age and gender the results still remained statistically significant. CONCLUSIONS Overweight/obesity prevalence among children six to ten years old in NEHR of Jamaica is 17.7% with older children and girls having higher rates. Children attending urban-public and private schools have higher prevalence than those attending rural schools. Appropriately targeted interventions are needed to combat this problem.

Abstract
OBJECTIVES The sickle gene frequency in the Jamaican population has not changed over a generation. It is unknown whether routine antenatal screening for sickle cell trait (SCT) has affected women's knowledge of their SCT status. The aim of this study was to compare the prevalence of self-reported SCT in parous women to the prevalence in nulliparous women, men and to the observed prevalence of SCT measured in an antenatal clinic. METHODS All participants in the nationally representative Jamaica Health and Lifestyle Survey 2008 were asked whether they had the SCT. The impact of gender, age, educational attainment, geographical location, and pregnancy on self-reported SCT were assessed. The prevalence of SCT in women attending a large antenatal clinic concurrently was compared to that reported by women of child-bearing age in the lifestyle survey. RESULTS Self-report significantly underestimated the prevalence of SCT (2·9% versus 10·1%, P<0·001). Those with secondary education were more likely than those with presecondary education (P = 0·01) and women more likely than men (3·2% versus 1·1%, P = 0·001) to report having SCT. Women who had been pregnant were no more likely than other women to report having SCT (3·1% versus 4·1%, P = 0·4). CONCLUSIONS Attendance at antenatal clinic where SCT screening is routine, is not associated with increased self-report of SCT. Screening programs must ensure that, as well as technically accurate screening, there is effective communication of the results of screening for SCT to those tested to help reduce the public health burden of sickle cell disease in tropical countries.

Abstract
OBJECTIVES To estimate the incidence of hypertension in people with and without prehypertension and determine the factors that predict progression to hypertension. METHODS Data from a cohort of 25-74-year-old residents of Spanish Town, Jamaica, were analysed. All participants completed a structured questionnaire and had blood pressure (BP), anthropometric measurements and venous blood sampling performed by trained personnel. Blood Pressure was classified using the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation and Treatment of High Blood Pressure (JNC-7) criteria. RESULTS 708 persons who had the required data and were not hypertensive at baseline were included in this analysis. Mean follow-up time was 4.1 years; 28.7% of prehypertensive participants developed hypertension compared to 6.2% of normotensive participants. The unadjusted incidence rate ratio (IRR [95% CI]) for progression among prehypertensive compared to normotensive participants was 4.62 [2.96, 7.43]. Among males, the rate of progression to hypertension was significantly higher for those 45-64 years old and those who were current smokers. Among females, progression was higher for age groups 25-44 years, 45-64 years, those who were overweight (BMI > or =25), obese (BMI > or =30) and current smokers. In multivariate models, prehypertension, female gender overweight status and older age remained significantly associated with progression to hypertension among the combined prehypertensive and normotensive groups. IRR [95% CI] were: prehypertension, 3.45 [2.18-5.45]; female gender 1.81 [1.12, 2.94]; overweight, 1.87 [1.15, 2.94]; age 45-64 years, 1.73 [1.08, 2.76]; age > 65 years 2.39 [1.31, 4.34]. CONCLUSIONS Prehypertension is associated with a three-fold increase in the incidence of hypertension. Higher BMI, age and female gender also independently predict the development of hypertension.

Abstract
OBJECTIVE To estimate the prevalence of the metabolic syndrome in Jamaican adults and to evaluate its association with socio-economic status (SES). METHODS A cross-sectional analysis was performed using data from a cohort study of persons, 25-74 years old, living in St Catherine, Jamaica, and who were evaluated between 1993 and 2001. Participants completed an interviewer administered questionnaire and had blood pressure and anthropometric measurements performed by trained observers. Venous blood was collected for measurement of fasting glucose and lipids. The metabolic syndrome was defined using the International Diabetes Federation (IDF) and American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria. Income and education were used as markers of SES. RESULTS Data from 1870 participants (717 males 1153 females) were analysed. Prevalence of the metabolic syndrome was 21.1% (95% CI 19.2, 22.9%) using IDF criteria and 18.4% (95% CI 16.6, 20.2%) using the AHA/NHLBI criteria. Prevalence was higher among females (27.6% [IDF], 23.0% [AHA]) compared to males (10.6% [IDF], 11.0% [AHA]). The prevalence of the metabolic syndrome increased with age. Compared to males with primary/lower education, those with secondary and tertiary education had higher odds of having the metabolic syndrome after adjusting for age; odds ratio 3.12 (1.54, 6.34) and 2.61 (1.33, 5.11) respectively. High income was also associated with increased odds of having the metabolic syndrome among males, OR = 6.0 (2.22, 16.19) adjusting for age-group. There were no significant associations among women. CONCLUSION The metabolic syndrome is common in Jamaica. Clinicians should look for this syndrome in their patients and take steps to treat the abnormalities identified.

Abstract
OBJECTIVE To compare perinatal and social factors in students admitted to The University of the West Indies (UWI), Kingston, Jamaica, at age 18 years with those in the rest of the Jamaican Perinatal Cohort. METHOD The Jamaican Perinatal Survey recorded demographic and perinatal details in 10 527 or 97% of births in Jamaica in September and October 1986. Eighteen years later 140 of these were admitted to the UWI in Kingston, Jamaica. The perinatal features of these UWI students have been compared with the rest of the Perinatal Survey Cohort. RESULTS Mothers of UWI students were older (p < 0.001), more likely to be married at the time of birth (p < 0.001), had earlier and more complete antenatal care (p < 0.05) and greater educational achievement at time of pregnancy (p < 0.001). These mothers of UWI students were also more likely to have diabetes (p < 0.01), operative deliveries (p < 0.01) and to attend private hospitals (p < 0.01). The UWI students had fewer siblings by their mothers (p < 0.05), were less likely to be low birthweight babies (p = 0.035) and more likely to be full-term (37-42 weeks) than lower gestational age (p = 0.005). Differences in Apgar scores did not reach statistical significance. CONCLUSIONS The students of the University of the West Indies were more likely to come from smaller families with features indicative of a better quality of life. They were also of higher birthweight and tended to be full-term. The lack of association of Apgar scores with educational attainment is noteworthy.

Abstract
OBJECTIVE To examine the pattern of stroke subtypes found on Computed Tomography (CT), Magnetic Resonance Imaging (MRI) at the University Hospital of the West Indies (UHWI), Kingston, Jamaica. METHOD A retrospective review was conducted for all patients diagnosed with stroke and who were subjected to CT or MRI evaluation at UHWI between January 2001 and December 2004. Data were collected for patient age and gender and type of stroke. RESULTS Four hundred and thirty-three patients were identified and classified as having cerebral infarct, intra-parenchymal haemorrhage or subarachnoid haemorrhage. There were 414 patients who had CT scans and 19 had MRI scans. Within and across genders, over 80% suffered infarcts with no significant statistical difference between male and female patients. Subarachnoid haemorrhage was the least frequent subtype and occurred in younger patients. CONCLUSION The pattern of stroke subtypes seen in this population was similar to that of Australian and European cohorts of patients but differed from that reported in Asians. Ischaemic infarct was the most frequent stroke subtype followed by intra- parenchymal haemorrhage and subarachnoid haemorrhage. There was no gender predilection for any specific type of stroke.

Abstract
Background Disparities in cervical cancer incidence and mortality rates exist among women of African ancestry (African-American, African-Caribbean and African). Persistent cervical infection with Human papillomavirus (HPV) is associated with cervical dysplasia and if untreated, could potentially progress to invasive cervical cancer. Very few studies have been conducted to examine the true prevalence of HPV infection in this population. Comparisons of cervical HPV infection and the type-specific distribution of HPV were performed between cancer-free Caribbean and US women. Results The Caribbean population consisted of 212 women from Tobago and 99 women from Jamaica. The US population tested, consisted of 82 women from Pittsburgh. The majority of the US subjects was Caucasian, 74% (61/82) while 12% (10/82) and 13% (11/82) were African-American or other ethnic groups, respectively. The age-adjusted prevalence of any HPV infection among women from Tobago was 35%, while for Jamaica, it was 81% (p < 0.0001). The age-adjusted prevalence of HPV infection for Caribbean subjects was not statistically significantly different from the US (any HPV: 47% vs. 39%, p > 0.1; high-risk HPVs: 27% vs. 25%, p > 0.1); no difference was observed between US-Blacks and Jamaicans (any HPV: 92% vs. 81%, p > 0.1; high-risk HPV: 50% vs. 53%, p > 0.1). However, US-Whites had a lower age-adjusted prevalence of HPV infections compared to Jamaican subjects (any HPV: 29% vs. 81%, p < 0.0001; high-risk HPV: 20% vs. 53%, p < 0.001). Subjects from Jamaica, Tobago, and US-Blacks had a higher proportion of high-risk HPV infections (Tobago: 20%, Jamaica: 58%, US-Blacks: 40%) compared to US-Whites (15%). Similar observations were made for the presence of infections with multiple high-risk HPV types (Tobago: 12%, Jamaica: 43%, US-Blacks: 30%, US-Whites: 8%). Although we observed similar prevalence of HPV16 infections among Caribbean and US-White women, there was a distinct distribution of high-risk HPV types when comparisons were made between the ethnic groups. Conclusion The higher prevalence of cervical HPV infections and multiple high-risk infections in Caribbean and US-Black women may contribute to the high incidence and prevalence of cervical cancer in these populations. Evaluation of a larger sample size is currently ongoing to confirm the distinct distribution of HPV types between ethnic groups.

Abstract
OBJECTIVES To determine the relationship of diet to overweight and obesity among populations of African origin. DESIGN AND SETTING Cross-sectional data were obtained from adults aged 25-74 years in rural Cameroon (n = 686), urban Cameroon (n = 975), Jamaica (n = 924) and Afro-Caribbeans in the UK (n = 257). Dietary data were collected using food-frequency questionnaires specifically designed for each site. Body mass index (BMI) was used as a measure of overweight. RESULTS The expected gradient in the distribution of overweight across sites was seen in females (rural Cameroon, 9.5%; urban Cameroon, 47.1%; Jamaica, 63.8%; UK, 71.6%); however, among males overweight was less prevalent in Jamaica (22.0%) than urban Cameroon (36.3%). In developing countries increased risks of overweight (BMI > or = 25 kg m(-2) were influenced by higher energy (urban Cameroonian men) and protein (Jamaican women) intakes. No dietary variables were associated with obesity (BMI > or = 30 kg m(-2) in Cameroon or Jamaica. In the UK, energy intakes were inversely related with overweight whereas increased risks of being overweight were associated with higher protein (men) and fat (women) intakes. Similarly, whereas higher protein and fat intakes in UK men and women were associated with obesity, carbohydrate intakes were associated with decreased risks of obesity in men. CONCLUSIONS Diet and overweight were associated in the UK but few dietary variables were related to overweight in Jamaica and the Cameroon. These findings suggest that associations between diet and overweight/obesity are not generalisable among populations.

Abstract
The interference in the metabolism of a drug by another drug, food or other foreign chemical is commonly observed and often leads to clinically significant adverse drug reactions. In Jamaica, there is an extensive use of natural products as medicines, although there is little information on whether natural medicines are used along with prescription medicines, which might increase the likelihood of drug adversities. This current pilot survey was initiated to gain information on the prevalence of such polypharmacy practices. Two concurrent surveys were carried out in Kingston (an urban parish) and Clarendon (a rural parish) in 743 patients above age 14 years with diabetes mellitus, hypertension and gastrointestinal disorders of persons who visited health centres and pharmacies. Patrons visiting these places at various times of the day were informed of the nature of the questionnaire and willing participants with the above disease conditions and who were on prescription medicines were included in the survey. The results indicated that 80% of the respondents reported combining natural products in their treatment along with prescription medicines, with only 13% of those patients informing their physicians of such practices. Such polypharmacy practices were independent of the type of disease among both males and females and was statistically most prevalent (p < 0.001) in the 47-57-year age group. There was a significant association (p < 0.001) between such treatment practices and place of residence with 92% of the rural community engaging in polypharmacy but 70% of the urban did likewise. Therefore, being aware of the prevalence of multiple therapy practices would be especially useful when designing a pharmaco-vigilance system.

Abstract
As type 2 diabetes mellitus (DM2), obesity and sedentary lifestyles are increasing in developing countries, this observational study investigated the role of physical activity on DM2 in Jamaica. Anthropometry, body composition (by bioelectrical impedance analysis) and glucose tolerance status was assessed in 722 adults in 1993 and 1997. Energy expenditure was estimated in a subset using measured resting energy expenditure in combination with self-reported activity recalls. The rates of impaired glucose tolerance (IGT) were 23.7 and 27.3%, and DM2 were 16.3 and 23.7% among men and women, respectively. After adjusting for body composition, a one-unit increase in physical activity significantly reduced the odds of having diabetes (OR = 0.05; 95% CI: 0.004, 0.66), but not IGT. Hence, decreased physical activity is a significant independent contributor to the high rates of glucose intolerance in Jamaica. Efforts must be directed at minimizing obesity and increasing physical activity in developing countries.

Abstract
The world-wide epidemic of Human Immunodeficiency Virus/Acquired Immune Deficiency Syndrome (HIV/AIDS) has led to an increase in the number of HIV positive children, mainly through perinatal transmission. HIV/AIDS can lead to severe childhood malnutrition (SCM) and has been noted as an increasingly common cause of secondary SCM. In this context, it is important to make assessments of the appropriateness of current approaches to treatment of severe malnutrition in HIV positive children. A retrospective matched case-control study of ten HIV positive children admitted to the Tropical Metabolism Research Unit (TMRU) was conducted. There were few differences between cases and matched controls on admission to the ward. Oral candidiasis and lower respiratory tract infections appeared to occur more frequently, and serum globulin concentrations were significantly higher among HIV positive cases when compared to their controls. Despite the fact that the differences between cases and controls appeared to be small, four cases died; there were no deaths among the controls. The duration of the maintenance phase was approximately five days longer (p = 0.024) among cases than controls but the time between the end of the maintenance phase and discharge from the ward was not significantly longer for the cases. The results of this matched case-control study suggest that there are likely to be important differences between HIV positive and negative patients with SCM that influence risk of mortality and morbidity, particularly in the maintenance phase of treatment. Prospective studies will be required in order to explore these differences and to develop better approaches to the care of HIV positive children with SCM.
