Protein and Dairy is an infographic and nutrition education material as part of project deliverables for the Immersive Learning Project at Ball State University that provides students with real-life community engagement and community nutrition training. The nutrition educational material provides information about types of protein, food sources, and the benefits of protein and dairy consumption. It also contains a recipe for healthy homemade biscuits and gravy., The infographic was designed by the senior Nutrition and Dietetic students of the Nutrition and Dietetic Program at the Department of Nutrition and Health Science, College of Health, Ball State University, Muncie, Indiana. All authors have equal contributions.

Background: We aimed to estimate the relative risk for elevated blood pressure (BP ≥ 120/80 mmHg) for cardiovascular disease (CVD) risk factors among Afro-Caribbean youth in Jamaica and to evaluate the association between clustering of risk factors and elevated BP. Methods: We analysed data from 898 young adults, 18-20 years old (409 males; 489 females) from the Jamaica 1986 Birth Cohort Study. BP was measured with a mercury sphygmomanometer after the participant had been seated for 5 minutes. Anthropometric measurements were done and venous blood obtained to measure fasting glucose, lipids and insulin. 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. Insulin resistance was estimated using the Homeostasis Model Assessment (HOMA-IR). Relative risks were computed using odds ratios (OR) from logistic regression models. Results: Prevalence of elevated BP was 30% among males and 13% among females (p Conclusion: Factors associated with elevated BP among Jamaican young adults include measures of obesity and insulin resistance, with significant differences by sex. Lower SES was associated with elevated BP among females. Clustering of risk factors was associated with markedly higher odds of elevated BP among males, but less so among females.

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 p 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 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.

Background In 1996 a study found that approximately one in four tourists to Jamaica were affected with traveler's diarrhea (TD) during their stay. That year the Ministry of Health initiated a program for the prevention and control of TD. The aim of this ongoing program was to reduce attack rates of TD from 25% to 12% over a 5-year period by improving the environmental health and food safety standards of hotels. Methods Hotel-based surveillance procedures for TD were implemented in sentinel hotels in Negril and Montego Bay in 1996, Ocho Rios in 1997, and Kingston in 1999. A structured program provided training and technical assistance to nurses, food and beverage staff, and environmental sanitation personnel in the implementation of Hazard Analysis Critical Control Point principles for monitoring food safety standards. The impact of interventions on TD was assessed in a survey of tourists departing from the international airport in Montego Bay in 1997–1998 and from the international airport in Kingston in 1999–2000. The impact of the training and technical assistance program on food safety standards and practices was assessed in hotels in Ocho Rios as of 1998 and in Kingston from 1999. Results At the end of May 2002, TD incidence rates were 72% lower than in 1996, when the Ministry of Health initiated its program for the prevention and control of TD. Both hotel surveillance data and airport surveillance data suggest that the vast majority of travelers to Kingston and southern regions are not afflicted with TD during their stay. The training and technical assistance program improved compliance to food safety standards over time. Conclusion Interventions to prevent and control TD in visitors to Jamaica are positively associated with a reduction in TD in the visitor population and improvements in food safety standards and practices in hotels.

Although rotavirus infections are generally considered to be confined to the intestine, recent reports suggest that extraintestinal disease occurs. We studied whether rotavirus infection was associated with antigenemia during a major outbreak of gastroenteritis in the Kingston metropolitan area, during July-August 2003. Rotavirus antigen was identified in 30 of 70 acute-phase serum samples (including from 2 deceased individuals) but in only 1 of 53 control samples. Serum antigen levels were inversely associated with time since symptom onset and were directly associated with antigen levels in stool (P = .02). Serum antigen levels were significantly elevated during primary infections (acute-phase serum immunoglobulin G [IgG] titers,25), compared with those in subsequent infections (acute-phase serum IgG titers,or = 25) (P = .02). Antigenemia was common in this outbreak and might provide a mechanism to help explain rare but well-documented reports of findings of extraintestinal rotavirus. In situations in which stool samples are not readily available (i.e., patients with severe dehydration or those recently recovered or deceased), serum testing by enzyme immunoassay offers a new and practical diagnostic tool.

OBJECTIVE: To determine the prevalence of experiences with physical violence and psychological violence that health staff have had in the workplace in Jamaica, and to identify factors associated with those experiences of violence. DESIGN AND METHODS: A total of 832 health staff answered the standardized questionnaire that was used in this cross-sectional study. Sampling was done at public facilities, including specialist, tertiary, and secondary hospitals in the Kingston Metropolitan Area; general hospitals in the rural parishes; and primary care centers in urban and rural areas. Sampling was also done in private hospitals and private medical centers. RESULTS: Psychological violence was more prevalent than was physical violence. Verbal abuse had been experienced in the preceding year by 38.6% of the questionnaire respondents, bullying was reported by 12.4%, and physical violence was reported by 7.7%. In multivariate analyses there was a lower risk of physical violence for health staff who were 55 years or older, worked during the night, or worked mostly with mentally disabled patients, geriatric patients, or HIV/AIDS patients. Staff members working mostly with psychiatric patients faced a higher risk of physical assaults than did other health staff. Of the various health occupations, nurses were the ones most likely to be verbally abused. In terms of age ranges, bullying was more commonly experienced by health staff 40-54 years old. CONCLUSIONS: Violence in the health sector workplace in Jamaica is an occupational hazard that is of public health concern. Evaluation of the environment that creates risks for violence is necessary to guide the formulation of meaningful interventions for the country.OBJETIVO: Determinar la prevalencia de experiencias con episodios de violencia física y psicológica en el lugar de trabajo entre miembros del personal de salud de Jamaica, así como los factores que se asocian con dichas experiencias. MÉTODOS: Un total de 832 miembros del personal de salud de plantilla respondieron al cuestionario estandarizado que se usó en este estudio transversal. La muestra se obtuvo en instalaciones públicas, entre ellas hospitales especializados, terciarios y secundarios de la zona metropolitana de Kingston; hospitales generales en las parroquias rurales; y centros de atención primaria de salud en zonas urbanas y rurales. También se hizo un muestreo en hospitales y centros médicos privados. RESULTADOS: La violencia psicológica fue más frecuente que la física. Durante el año anterior a la encuesta, 38,6% de los encuestados habían sido víctimas de abuso verbal; 12,4%, de acoso, y 7,7% de maltrato físico. En análisis multifactoriales se observó un menor riesgo de sufrir violencia física entre miembros del personal de salud que tenían 55 años de edad o más, que trabajaban de noche, o que trabajaban principalmente con pacientes mentalmente discapacitados, pacientes geriátricos, o pacientes con infección por VIH o sida. En los miembros del personal que trabajaban principalmente con pacientes psiquiátricos se detectó un mayor riesgo de sufrir ataques físicos que en otros trabajadores de la salud. De las diversas ocupaciones pertenecientes al ámbito de la salud, la de enfermería fue en la que más se halló la propensión a ser víctima de abuso verbal. En cuanto a grupos de edad, el acoso se observó con más frecuencia en trabajadores de salud entre las edades de 40 y 54 años. CONCLUSIONES: La violencia en el lugar de trabajo en Jamaica es un peligro ocupacional que merece la atención del sector sanitario. Es necesario evaluar el tipo de ambiente que propicia la violencia a fin de formular intervenciones eficaces en el país.

Involvement in violence is affected by a variety of risk factors and timing, duration, number of risks, and intensity of risk factors. The earlier the exposure to risk starts, the longer the exposure continues, the number of risks one is exposed to, and intensity of the risk factors experienced are all important. A child who is severely beaten, sexually abused, or both; one who grows up witnessing intimate partner or family violence; one who attends a failing school or is not involved in structured after-school activities; or one who lives in a violent neighborhood is at increased risk of becoming involved in violent behavior. The nature of the violence is worsened by the impact of shifting family structure and other risk factors such as alcohol and drugs. Adolescents who are exposed to positive parenting and supportive individuals, receive relevant education, are literate, possess life skills, and participate in structured, supervised activities become empowered young people who can resist violence.

As part of the reproductive health quality assurance programme, the Ministry of Health sought to review maternal deaths in public hospitals. These hospitals attend 95% of institutional births and 82% of all births.Deaths among females 10-50 years in public hospitals during 1993-1995 were reviewed to identify pregnancy-related deaths. Cause of death and access to care were compared with previous studies (1981-1983 and 1986-1987 [12 months]).The maternal mortality ratio of 106.2 per 100 000 live births, was no different than the 119.7 observed in 1986-1987 and 118.6 for 1981-1983. The leading causes of death remained pre-eclampsia/eclampsia and haemorrhage. The only significant cause-specific decline occurred among deaths due to ruptured ectopic pregnancy (P = 0.012). While in 1986-1987 access to care was associated with risk of death from gestational hypertension (P = 0.02), these differences are no longer significant. Differences persist, however, for haemorrhage and all other causes, which were less likely to occur at the more skilled institutions. The region with the least obstetricians had the highest mortality ratio but the one with the most did not have the lowest ratio, indicating that quality is more important than quantity.Regional differences indicate the capacity to reduce maternal mortality by at least 50% with re-allocation of skilled personnel and improved quality. All hospitals must be able to manage haemorrhage cases as patients are unlikely to survive referral.

Information concerning 9919 singleton pregnancies delivered in Jamaica in the 2-month period of September and October 1986 and surviving the early neonatal period were compared with 1847 singleton perinatal deaths occurring in the 12-month period from 1 September 1986 to 31 August 1987, classified according to the Wigglesworth schema. Logistic regression was used to assess features of antenatal and intrapartum care that were associated with the different groups of perinatal death after taking account of environmental, maternal and medical factors. In Jamaica, 67% of all mothers took iron during pregnancy. These mothers appeared to have a lower risk of perinatal death. This does not appear to be an artefact related to the gestation at which the mother delivers, and was particularly associated with antepartum fetal deaths. Commencement of antenatal care in the first trimester appeared to reduce the risk of all perinatal deaths, and for intrapartum asphyxia in particular. It is speculated that the mechanism may involve early detection and treatment of anaemia and syphilis. Quality of perinatal care available in the area of residence, as measured by the presence of consultant obstetricians and a paediatric consultant unit, is shown to be significantly related to a reduction in deaths from intrapartum asphyxia, but it appeared not to be related to antepartum fetal deaths.

Information from the Jamaican Perinatal Mortality Survey was used to identify features of mothers and their pregnancies that were independently associated with perinatal death. Social, biological, environmental, life style and medical aspects of mothers and their pregnancies were collected on two inter-locking subsamples: (1) all births on the island of Jamaica in the 2 months of September and October 1986, the 'cohort months', and (2) all fetal deaths of weight 500 g or more, together with all neonatal deaths, in the 12-month period from 1 September 1986 to 31 August 1987. Singleton survivors from the cohort months were compared with all perinatal deaths in the 12-month period using logistic regression. The first model omitted items concerning past obstetric history, but these were included in the second model. In total, 21 variables entered the first model and 24 the second. The only item that became non-significant when past obstetric history was included was maternal age. The final model compared 1017 perinatal deaths with 7672 survivors. It consisted of the following: union (marital) status (married being at lower risk, P < 0.01), maternal employment status (housewives at lowest risk, P < 0.001), number of adults in household (the more the higher the risk, P < 0.05), the number of children aged < 11 (the more the lower the risk, P < 0.0001), use of toilet facilities (shared with other households increased risk, P < 0.001), maternal height (tall women at reduced risk, P < 0.001), mother's report that she was trying to get pregnant (P < 0.001), maternal alcohol consumption (drinkers had lower risk, P < 0.05), maternal syphilis (higher risk, P < 0.0001), bleeding before 28 weeks (higher risk, P < 0.0001), bleeding at 28 weeks or more (higher risk, P < 0.0001), first diastolic blood pressure (80 mm + at higher risk, P < 0.0001), highest diastolic blood pressure (100 mm + at increased risk, P < 0.0001), highest proteinuria (++ or more at increased risk, P < 0.0001), vaginal discharge/infection (untreated at increased risk, P < 0.001), pre-eclampsia diagnosed in antenatal period (increased risk, P < 0.01), maternal diabetes (increased risk, P < 0.05), start of antenatal care (first trimester at reduced risk, P < 0.01), iron taken (reduced risk, P < 0.0001), type of perinatal care available in parish of residence (reduced risk if consultant obstetricians and paediatricians available at all times, P < 0.0001), number of miscarriages and terminations (the more the higher the risk, P < 0.0001), previous stillbirth (higher risk, P < 0.0001), previous early neonatal death (higher risk, P < 0.001), previous Caesarean section (higher risk, P < 0.01). The implications for reduction in perinatal mortality rates are discussed.

The Jamaican Perinatal Mortality Survey was designed to identify the true perinatal mortality rate, and assess the factors which could contribute towards a reduction in perinatal mortality on the island. All births in a 2-month period (n = 10527) were compared with all perinatal deaths occurring over a 12-month period (n = 2069). Over half the deaths (n = 1058) received a detailed post-mortem examination. Use of the Wigglesworth classification identifies the major component of perinatal death in this country to be associated with intrapartum asphyxia (44% of deaths). Deaths due to congenital malformations and miscellaneous causes contribute relatively little (< 10%) to the overall mortality rate. Over a quarter of deaths apparently occur before the onset of labour, and a fifth are prematurely liveborn but die of causes related to immaturity.

Summary. During the 12-month period from 1 September 1986 to 31 August 1987 an attempt was made to collect information on all perinatal deaths occurring on the island of Jamaica. Of the 2069 late fetal and early neonatal deaths identified, 19% fell into the Wigglesworth1 definition of ‘deaths from immaturity’. Twins were 11 times more likely to die of immaturity than were singletons, and twins comprised 18% of all deaths in this group. Comparison of the singleton deaths from immaturity, with 9919 singletons born on the island during the 2-month period of September and October 1987 and who survived the first 7 days, revealed several strong risk factors. These included history of previous miscarriages, stillbirth, early neonatal death or preterm delivery, and complications of bleeding and hypertension (highest diastolic, proteinuria and eclampsia all having independent associations). None of these factors ‘explained’ a strong negative relationship with the number of young children in the household. There was an apparent protective effect of maternal folic acid ingestion which warrants further investigation.

Background The metabolic syndrome has a high prevalence in many countries and has been associated with socioeconomic status (SES). This study aimed to estimate the prevalence of the metabolic syndrome and its components among Jamaican young adults and evaluate its association with parental SES. Methods A subset of the participants from the 1986 Jamaica Birth Cohort was evaluated at ages 18-20 years between 2005 and 2007. Trained research nurses obtained blood pressure and anthropometric measurements and collected a venous blood sample for measurement of lipids and glucose. Prevalence of the metabolic syndrome and its components were estimated using the 2009 Consensus Criteria from the International Diabetes Federation, National Heart Lung and Blood Institute, American Heart Association, World Heart Federation, International Atherosclerosis Society, and International Association for the Study of Obesity. SES was assessed by questionnaire using occupation of household head, highest education of parent/guardian, and housing tenure of parent/guardian. Analysis yielded means and proportions for metabolic syndrome variables and covariates. Associations with levels of SES variables were obtained using analysis of variance. Multivariable analysis was conducted using logistic regression models. Results Data from 839 participants (378 males; 461 females) were analyzed. Prevalence of the metabolic syndrome was 1.2% (95% confidence interval [95%CI] 0.5%-1.9%). Prevalence was higher in females (1.7% vs. 0.5%). Prevalence of the components [male: female] were: central obesity, 16.0% [5.3:24.7]; elevated blood pressure, 6.7% [10.8:3.3]; elevated glucose, 1.2% [2.1:0.4]; low HDL, 46.8% [28.8:61.6]; high triglycerides, 0.6% [0.5:0.6]. There were no significant differences in the prevalence of the metabolic syndrome for any of the SES measures used possibly due to lack of statistical power. Prevalence of central obesity was inversely associated with occupation (highly skilled 12.4%, skilled 13.5%, semi-skilled/unskilled 21.8%, p = 0.013) and education (tertiary 12.5%, secondary 14.1%, primary/all-age 28.4%, p = 0.002). In sex-specific multivariate logistic regression adjusted for hip circumference, central obesity remained associated with occupation and education for women only. Conclusion Prevalence of the metabolic syndrome is low, but central obesity and low HDL are present in 16% and 47% of Jamaican youth, respectively. Central obesity is inversely associated with occupation and education in females.

The aim of this study was to provide standards for the assessment of birthweight, head circumference and crown-heel length for normal, singleton newborns of predominantly West African descent. Data were collected for 10 482 or 94% of all recorded births in Jamaica during the two-month period September 1 to October 31, 1986. After editing procedures, data were available for 6178 (birthweight), 5975 (head circumference), and 5990 (crown-heel length). The data presented in tables and growth curves include birthweight, head circumference and crown-heel length for males and females separately, for gestational ages 30–43 weeks. Data sets from the University Hospital of the West Indies in 1990 and 1999 were used to explore the possibility of secular change over the period 1986–1999. In conclusion, these ethnic and gender-specific growth curves are based on the most extensive dataset currently available in Jamaica for babies of West African descent.

Background Health surveys provide important information on the burden and secular trends of risk factors and disease. Several factors including survey and item non-response can affect data quality. There are few reports on efficiency, validity and the impact of item non-response, from developing countries. This report examines factors associated with item non-response and study efficiency in a national health survey in a developing Caribbean island. Methods A national sample of participants aged 15–74 years was selected in a multi-stage sampling design accounting for 4 health regions and 14 parishes using enumeration districts as primary sampling units. Means and proportions of the variables of interest were compared between various categories. Non-response was defined as failure to provide an analyzable response. Linear and logistic regression models accounting for sample design and post-stratification weighting were used to identify independent correlates of recruitment efficiency and item non-response. Results We recruited 2012 15–74 year-olds (66.2% females) at a response rate of 87.6% with significant variation between regions (80.9% to 97.6%; p < 0.0001). Females outnumbered males in all parishes. The majority of subjects were recruited in a single visit, 39.1% required multiple visits varying significantly by region (27.0% to 49.8% [p < 0.0001]). Average interview time was 44.3 minutes with no variation between health regions, urban-rural residence, educational level, gender and SES; but increased significantly with older age category from 42.9 minutes in the youngest to 46.0 minutes in the oldest age category. Between 15.8% and 26.8% of persons did not provide responses for the number of sexual partners in the last year. Women and urban residents provided less data than their counterparts. Highest item non-response related to income at 30% with no gender difference but independently related to educational level, employment status, age group and health region. Characteristics of non-responders vary with types of questions. Conclusion Informative health surveys are possible in developing countries. While survey response rates may be satisfactory, item non-response was high in respect of income and sexual practice. In contrast to developed countries, non-response to questions on income is higher and has different correlates. These findings can inform future surveys.

The purpose of this study was to assess the prevalence of high risk health behaviours among adult Jamaicans aged 15-49 years in 2000, and to compare the results with the 1993 survey. A nationally representative sample of 2013 persons aged 15-74 years was surveyed in 2000 using cluster sampling in the Jamaica Healthy Lifestyle Survey (Wilks et al, unpublished). Interviewer administered questionnaires and anthropometrical measurements were done. Data for a sub-sample of adults aged 15-49 years were analyzed The sub-sample included 1401 persons (473 men and 928 women). Significantly more men (18.6%) than women (4.3%) reported never having had a blood pressure check (p = 0.0001). Approximately one-third of the women reported that they had never had a Pap smear (36.0%) or a breast examination (31.2%). Current cigarette smoking was reported in 28.6% of men and 7.7% of women (OR 3.73 CI 2.71, 5.15), while 49.0% of men and 15.0% of women ever smoked marijuana (OR 3.28 CI 2.56, 4.20). Significantly more men (28.0%) than women (11.7%) reported ever having a sexually transmitted disease (OR 2.93 CI 2.16, 3.97); having more than one sexual partner in the past year (49.1% vs 11.4%, OR 4.31 CI 3.22, 5.76) and usually using a condom during sexual intercourse (55.3% vs 40.5%, OR 1.3 CI 1.11, 1.68). Between 1993 and 2000, significant trends include: more persons reported having a blood pressure check, a reduction in multiple sexual partners, increased condom use at last sex (women), reduced crack/cocaine use (males) and increased marijuana smoking. Although there were some significant positive lifestyle trends between 1993 and 2000, high risk behaviours remain common among Jamaican adults. Comprehensive health promotion programmes are needed to address these risk behaviours.

Exposure to violence in childhood is associated with aggression in adulthood. The high level of community violence in Jamaica is likely to expose Jamaican children to violence. There has been no detailed study of the exposure of Jamaican children to violence in their daily lives. Some 1674 urban 11-12-year-old children, previously part of a national birth cohort study, completed a questionnaire detailing their exposure to violence as witnesses, victims and aggressors. Their parents completed a socio-economic questionnaire. Jamaican children had high levels of exposure to physical violence. A quarter of the children had witnessed severe acts of physical violence such as robbery, shooting and gang wars, a fifth had been victims of serious threats or robbery and one in every twelve had been stabbed. Children reported being least exposed to sexual violence and to being shot at. Robbery was an almost universal experience affecting children from all schools and socio-economic groups. The single commonest experience as a victim of violence was the loss of a family member or close friend to murder, affecting 36.8% of children. Children's experiences of witnessing violence occurred chiefly in their communities but their personal experiences of violence occurred at school. Boys and children attending primary school had greater exposure to violence as witnesses and victims. Socio-economic status discriminated exposure to physical violence as witnesses but not as victims. Intervention strategies to reduce children's exposure to violence should include community education on the impact of exposure to violence on children, particularly the loss of a significant person, and the development of a range of school-based violence prevention programmes.

Objective:To determine the nutritional status of a cohort of 11–12 year olds and ascertain social and demographic factors associated with under- and overweight in early adolescence.Design:Cross-sectional.Subjects:Subgroup (n=1698) of the birth cohort (September–October 1986) of the Jamaican Perinatal Survey enrolled in schools in the Kingston Metropolitan area. One thousand and sixty-three parents or caregivers provided social and demographic information.Results:Undernutrition and overnutrition are of public health significance among adolescent Jamaican children. Ten per cent of 11–12 year olds had body mass index (BMI) values below the 5th percentile (boys, 10.6%; girls, 7.1%) but this prevalence is relatively low compared with other developing countries. The prevalence of stunting was low (3%). The prevalence of overweight (BMI≥85th percentile) (19.3%) was approaching prevalence rates found in the USA. Similar social and demographic variables were associated with thinness and fatness in males. Birth weight predicted overweight in girls.Conclusions:Under- and overnutrition in early adolescence are important problems in Jamaica. There is a need to address both under- and overnutrition in adolescence in preventive and rehabilitative intervention programmes.

After an outbreak in 2000 of eosinophilic meningitis in tourists to Jamaica, we looked for Angiostrongylus cantonensis in rats and snails on the island. Overall, 22% (24/109) of rats harbored adult worms, and 8% (4/48) of snails harbored A. cantonensis larvae. This report is the first of enzootic A. cantonensis infection in Jamaica, providing evidence that this parasite is likely to cause human cases of eosinophilic meningitis.

Objective: In this study we examined the effects of birth weight (BWT) and early life socioeconomic circumstances (SEC) on systolic and diastolic blood pressure (SBP, DBP) among Jamaican young adults. Study Design and Setting: Longitudinal study of 364 men and 430 women from the Jamaica 1986 Birth Cohort Study. Information on maternal SEC at birth and BWT were linked to information collected at 18-20 years old. Sex-specific multilevel linear regression models were used to examine whether adult SBP and DBP were associated with BWT and maternal SEC. Results: In unadjusted models, SBP was inversely related to BWT z-score in both men and women (beta = -0.82 and -1.18, respectively) but achieved statistical significance for women only. After adjustments for current age, current BMI, current height, maternal age and mother's occupation at child's birth, a one standard deviation (SD) unit increase in BWT was associated with 1.16 mmHg reduction in SBP among men (95%CI -2.15, -0.17; p=0.021) and a 1.34 mmHg reduction in SBP among women (95%CI -2.21, -0.47; p=0.003). High maternal occupational SEC at birth was consistently associated with lowest SBP across the standardized BWT distribution. SBP was 2-4 mmHg lower among those with high SEC mothers at birth than among those whose mothers were unemployed at birth. Conclusion: SBP at 18-20 years-old was lowest among those whose mothers had high SEC at birth and was inversely related to BWT.

Vital statistics underestimate the prevalence of perinatal and infant deaths. This is particularly significant when these parameters affect eligibility for international assistance for newly emerging nations.To determine the level of registration of livebirths, stillbirths and infant deaths in Jamaica.Births, stillbirths and neonatal deaths identified during a cross-sectional study (1986); and infant deaths identified in six parishes (1993) were matched to vital registration documents filed with the Registrar General.While 94% of livebirths were registered by one year of age (1986), only 13% of stillbirths (1986) and 25% of infant deaths (1993) were registered. Post neonatal deaths were more likely to be registered than early neonatal deaths. Frequently the birth was not registered when the infant died. Birth registration rates were highest in parishes with high rates of hospital deliveries (rs = 0.97, P0.001) where institutions notify the registrar of each birth. Hospital deaths, however, were less likely to be registered than community deaths as registrars are not automatically notified of these deaths.To improve vital registration, institutions should become registration centres for all vital events occurring there (births, stillbirths, deaths). Recommendations aimed at modernizing the vital registration system in Jamaica and other developing countries are also made.Vital statistics indicate only part of the actual prevalence of perinatal and infant mortality. Findings are reported from a study conducted to determine the level of registration of live births, stillbirths, and infant deaths in Jamaica. Births, stillbirths, and neonatal deaths identified during a 1986 cross-sectional study and infant deaths identified in six parishes during 1993 were matched to vital registration documents filed with the Registrar General. While 94% of live births were registered by one year of age, only 13% of stillbirths and 25% of infant deaths were so registered. Post neonatal deaths were more likely to be registered than early neonatal deaths. Frequently the birth was not registered when the infant died. Birth registration rates were highest in parishes with high rates of hospital deliveries where institutions notify the registrar of each birth. Hospital deaths, however, were less likely to be registered than community deaths since registrars are not automatically noticed of such deaths. Institutions should register all vital events occurring there.

Summary. The Jamaican Perinatal Mortality Survey compared all 2069 perinatal deaths occurring during the 12 months between 1 September 1986 and 31 August 1987 with 10086 survivors born in the 2 months of September and October 1986. The Wigglesworth classification identified 44% of the deaths as attributable to intrapartum asphyxia (IPA), and this grouping was largely confirmed by post-mortem examination where it had been carried out. About half of these babies weighed 2500 g + and death should have been largely preventable. Comparison of the 813 IPA singleton deaths with 9919 singleton survivors using logistic regression showed independent associations with maternal employment status, the number of children in the household, maternal height, whether or not the mother was trying to get pregnant, or had ever used an intrauterine contraceptive device. Medical conditions such as syphilis, untreated vaginal infection, bleeding < 28 weeks, bleeding 28+ weeks, highest diastolic and first diastolic blood pressures and eclamptic fits antenatally were all strongly associated. Mothers who commenced antenatal care in the first trimester were at reduced risk as were those who took iron during pregnancy. There were substantial reductions in mortality in areas where better medical facilities were available. To this model, features of previous obstetric history were offered, but the only variables which entered were those relating to prior perinatal deaths and immediately preceding miscarriage and termination. Examination of specific features in the management of labour and delivery is a logical basis for the introduction of changes in practice. Caesarean section is unlikely to be appropriate but it is suggested that more active interventions in terms of use of forceps and/or vacuum extraction may be useful.

In an attempt to identify causes of perinatal mortality and thence devise preventative strategies on the island of Jamaica, a study was made of the 1847 singleton perinatal deaths occurring over the 12-month period between 1 September 1986 and 31 August 1987. Complications of the pregnancy were elicited by questioning the mother as well abstracting data from the antenatal and clinical obstetric records. The deaths were classified using the Wigglesworth categorisation and the three largest groups were chosen for special study: antepartum fetal deaths, deaths of live birth from immaturity and deaths from intrapartum asphyxia. The medical features of the pregnancies were compared with data similarly obtained from 9919 women delivering singletons in the 2 months of September and October 1986 and who survived the first week of life. Unadjusted statistically significant associations were found with maternal syphilis, vaginal infection or discharge, bleeding in the first two trimesters, bleeding in the third trimester, lowest haemoglobin, highest diastolic and first diastolic blood pressures, highest level of proteinuria, diabetes and antenatal eclampsia. Logistic regression taking account of social, environmental and health behaviour variables showed the following significant relationships. Antepartum fetal death was associated with adjusted odds ratio (AOR) for syphilis 2.88 [95% confidence interval (CI): 1.91, 4.32], bleeding in third trimester 3.86 [2.73, 5.44], highest diastolic blood pressure (P < 0.0001), highest level of proteinuria (P < 0.0001), lowest Hb (P < 0.0001) and antenatal eclamptic fits AOR 4.62 [1.47, 14.50]. Deaths from immaturity were independently associated with bleeding < 28 weeks AOR 3.50 [2.39, 5.13], bleeding 28 + weeks AOR 1.93 [1.16, 3.22], highest diastolic blood pressure (P < 0.01) and highest level of proteinuria (P < 0.0001). Infection featured in deaths associated with intrapartum asphyxia, with syphilis AOR 2.17 [1.44, 3.26] and vaginal infection/discharge (P < 0.01) independently associated; other strong associations were bleeding < 28 weeks AOR 2.10 [1.57, 2.81], bleeding 28 + weeks AOR 2.32 [1.62, 3.33], highest diastolic blood pressure (P < 0.0001), first diastolic blood pressure (P < 0.0001) and antenatal eclampsia AOR 6.70 [2.63, 17.13]. For all perinatal deaths combined, independent features were syphilis AOR 2.06 [1.49, 2.85], vaginal infection/discharge (P < 0.001), bleeding < 28 weeks AOR 2.01 [1.60, 2.53], bleeding 28 + weeks AOR 2.65 [2.02, 3.48], highest diastolic blood pressure (P < 0.0001), first diastolic blood pressure (P < 0.0001), proteinuria (P < 0.0001) and antenatal eclampsia AOR 4.22 [1.76, 10.14]. The results help identify areas for monitoring and identifying pregnancies at highest risk.

Background Recent studies have documented an increased risk of cardiovascular disease (CVD) in persons with systolic blood pressures of 120–139 mmHg and/or diastolic blood pressures of 80–89 mmHg, classified as prehypertension in the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. In this paper we estimate the prevalence of prehypertension in Jamaica and evaluate the relationship between prehypertension and other risk factors for CVD. Methods The study used data from participants in the Jamaica Lifestyle Survey conducted from 2000–2001. A sample of 2012 persons, 15–74 years old, completed an interviewer administered questionnaire and had anthropometric and blood pressure measurements performed by trained observers using standardized procedures. Fasting glucose and total cholesterol were measured using a capillary blood sample. Analysis yielded crude, and sex-specific prevalence estimates for prehypertension and other CVD risk factors. Odds ratios for associations of prehypertension with CVD risk factors were obtained using logistic regression. Results The prevalence of prehypertension among Jamaicans was 30% (95% confidence interval [CI] 27%–33%). Prehypertension was more common in males, 35% (CI 31%–39%), than females, 25% (CI 22%–28%). Almost 46% of participants were overweight; 19.7% were obese; 14.6% had hypercholesterolemia; 7.2% had diabetes mellitus and 17.8% smoked cigarettes. With the exception of cigarette smoking and low physical activity, all the CVD risk factors had significantly higher prevalence in the prehypertensive and hypertensive groups (p for trend < 0.001) compared to the normotensive group. Odds of obesity, overweight, high cholesterol and increased waist circumference were significantly higher among younger prehypertensive participants (15–44 years-old) when compared to normotensive young participants, but not among those 45–74 years-old. Among men, being prehypertensive increased the odds of having >/=3 CVD risk factors versus no risk factors almost three-fold (odds ratio [OR] 2.8 [CI 1.1–7.2]) while among women the odds of >/=3 CVD risk factors was increased two-fold (OR 2.0 [CI 1.3–3.8]) Conclusion Prehypertension occurs in 30% of Jamaicans and is associated with increased prevalence of other CVD risk factors. Health-care providers should recognize the increased CVD risk of prehypertension and should seek to identify and treat modifiable risk factors in these persons.
