Neural tube defects in Jamaica following Hurricane Gilbert.

An increased incidence of obvious live-birth neural tube defects (i.e., spina bifida cystica and encephalocele) occurred in Jamaica 11 to 18 months after Hurricane Gilbert. The conceptions of the affected babies coincided with a rise in megaloblastic change in sickle cell patients, suggesting a wide-spread drop in dietary folate intake. A detailed history was taken from each of the 17 affected mothers (case subjects) and 51 unaffected mothers (matched control subjects). The case subjects reported a significantly lower mean intake of dietary folate in the periconceptional period (154 micrograms/day) than did the control subjects (254 micrograms/day). The temporary increase in neural tube defects was associated with a diet comparatively low in folate in the periconceptional period, suggesting the dietary level of folate that fails to protect against neural tube defects under natural conditions.

Lifestyles of Jamaican men with hypertension.

Purpose: Determine the extent to which the lifestyles of Jamaican men with hypertension met the guidelines of the Seventh Report of the Joint National Committee on the Prevention, Detection, Evaluation, and Treatment of High Blood Pressure (JNC 7). Design and Methods: Following informed consent, a convenience sample of Jamaican men with hypertension (n = 48), of African ethnicity, attending a Type 5 Health Center was interviewed over a four week period, using a 31-item interview schedule. Results: Mean age of respondents was 65.2 (± 12.1) years (range = 35-89 years) with 33% having blood pressure (BP) controlled to 130/80 mmHg. Those meeting the guidelines were normal weight 23 (47.9%), DASH (dietary approaches to stop hypertension) diet zero, medication 7 (14.6%), exercise 14 (29.2%), alcohol restriction 38 (79.2%), and smoking cessation 40 (83.3%). Medication adherence was associated with BP control (r = −0.30, p < .04). More than half of the respondents believed that hypertension could be cured and that they could stop all treatment if their BP was normal. Discussion and Conclusions: Only a third of the sample had BP controlled to ≤130/80 mmHg. Adherence to the JNC 7 lifestyle guidelines was inadequate. Implications for Practice: A nurse led intervention, focusing on perceptions and lifestyle practices, is indicated.
