Predictors of physical activity energy expenditure in Afro-Caribbean children.

BACKGROUND/OBJECTIVES: We hypothesized that maternal size during pregnancy and birth size are determinants of childhood physical activity energy expenditure (PAEE). Also, childhood PAEE is inversely related to adiposity and levels of cardiovascular risk factors. SUBJECTS/METHODS: The Vulnerable Windows Cohort Study is a longitudinal observational study of 569 Afro-Jamaican mothers recruited from the first trimester and their offspring. Anthropometry, bioelectrical impedance, PAEE (using the Actical monitor) and cardiovascular risk factors (blood pressure, fasting glucose, insulin and lipids) were measured in 124 boys and 160 girls at a mean age of 13.2 years. RESULTS: Boys had more fat-free mass (FFM) and expended more energy than girls (12.3±3.3 vs 9.6±2.8 kcal/kg/day; P<0.001). Maternal weight was associated with child's PAEE (r=0.29; P<0.001). PAEE was not significantly associated with birth weight. Maternal weight, after adjusting for child's age and sex, was positively associated with the child's FFM, fat mass and %fat (P-values 0.01). Age- and sex-adjusted PAEE was positively associated with FFM, fat mass and % fat (P-values <0.001), but not after adjusting for current weight. Age- and sex-adjusted PAEE was positively associated with triglycerides, insulin and systolic blood pressure (P-values <0.05), but not after adjusting for weight and height. PAEE was associated with fasting glucose after controlling for age, sex, weight and height (r=-0.12; P=0.02). CONCLUSIONS: Maternal size, but not birth weight, is a determinant of childhood PAEE. PAEE is not strongly associated with childhood body composition, but is inversely related to fasting glucose concentration.

An assessment of the process of informed consent at the University Hospital of the West Indies.

OBJECTIVE: To assess the adequacy of the process of informed consent for surgical patients at the University Hospital of the West Indies. METHOD: The study is a prospective, cross-sectional, descriptive study. 210 patients at the University Hospital of the West Indies were interviewed using a standardised investigator-administered questionnaire, developed by the authors, after obtaining witnessed, informed consent for participation in the study. Data were analysed using SPSS V.12 for Windows. RESULTS: Of the patients, 39.4% were male. Of the surgical procedures, 68.6% were scheduled, 7.6% urgent and 23.8% emergency, 35.2% were minor and 64.8% major. Information imparted/received was acceptable in 40% of cases, good in 24% and inadequate (unacceptable) in 36% of cases. Almost all (97.6%) patients stated that they understood why an operation was planned and 93.3% thought that they had given informed consent. Most (95.2%) thought that they had free choice and made up their own mind. A quarter (25.2%) of all patients were told that it was mandatory for them to sign the form. There was a discussion of possible side effects and complications in 56.7% of patients. CONCLUSIONS: This study clearly indicates that surgical patients at the University Hospital of the West Indies feel that they have given informed consent. However, it also suggests that more information should be given to patients for consent to be truly informed.

The roles and responsibilities of physicians in Pre-Hospital Emergency Medical Services: A Caribbean perspective.

A Pre-hospital Emergency Medical Service (PHEMS) is a vital component of a country's health service because it provides early medical care to critically ill and injured persons in the field There is evidence to show that early care reduces mortality and morbidity and offers the patient the best chance of survival and improved quality of life. Caribbean territories have been developing their PHEMS as part of a programme of health sector reform. In a study of PHEMS in 12 Caribbean countries, the Pan American Health Organization reported that there were no clear guidelines with respect to the roles and responsibilities of the physician in PHEMS in the majority of countries. In fact, a few countries had services where there was no direct physician involvement. We present a brief review of the internationally recognized roles and responsibilities of physicians in PHEMS, and make recommendations with particular reference to the Caribbean. We suggest that there is a need for direct and active involvement of physicians in the development of PHEMS because the Emergency Medical Technician is recognized as an extension of the physician in the field and is supposed to be protected by the physician's licence to deliver medical care.

El servicio médico de emergencia pre-hospitalaria (SMEPH) es un componente vital del servicio de salud de un país, porque provee atención médica temprana y sobre el terreno a personas accidentadas o enfermas en estado crítico. Las evidencias indican que la atención temprana reduce la mortalidad y la morbosidad, a la vez que ofrece al paciente la mejor oportunidad posible de sobrevivir y mejorar la calidad de vida. Los territorios caribeños han estado desarrollando su SMEPH como parte de un programa de reforma del sector de la salud. En un estudio del SMEPH en 12 países caribeños, la Organización Panamericana de la Salud informó que no había directrices claras con respecto a las funciones y responsabilidades del médico en el SMEPH en la mayoría de países. De hecho, unos países tenían servicios en los que no había participación directa del médico. Presentamos aquí una revisión breve de las funciones y responsabilidades reconocidas internacionalmente para los médicos en el SMEPH, y hacemos recomendaciones con referencia particular al Caribe. Sugerimos que hay necesidad de que los médicos participen de manera activa y directa en el desarrollo del SMEPH, porque el técnico médico de emergencia es reconocido como una extensión del médico sobre el terreno, y se supone que esté amparado por una licencia para impartir atención médica.
