Decrease in blood triglycerides associated with the consumption of eggs of hens fed with food supplemented with fish oil.

BACKGROUND: n-3 polyunsaturated fatty acids (n-3 PUFA) convey several health benefits, including a reduction of serum concentration of triglycerides (TG). AIM: To examine the effect on blood lipids, particularly TG, of a diet with n-3 PUFA enriched eggs in healthy volunteers in the Seychelles (Indian Ocean). METHODS: Double-blind crossover trial with one group of volunteers fed with 5 normal eggs per week during 3 weeks followed by 5 enriched eggs per week during the next 3 weeks while the other group received eggs in the inverse sequence. Hen feed was supplemented at 5% with tuna oil. Enriched eggs contained nine times more n-3 PUFA than usual eggs (mainly docosahexaenoic acid). RESULTS: Twenty-five healthy volunteers participated in the study. Based on pooled results observed during the two 3-week periods, consumption of enriched eggs was associated with a significant 16-18% decrease in serum triglycerides (P<0.01) but with no significant difference in serum LDL-cholesterol and HDL-cholesterol. Serum LDL-cholesterol increased during the first 3-week period and decreased during the second 3-week period with both normal and enriched eggs. Participants did not report a systematic preference for either type of eggs. CONCLUSIONS: Reasonable consumption of n-3 PUFA enriched eggs was associated with a significant decrease in serum triglycerides. These eggs could be a palatably acceptable source of n-3 PUFA.

Monitoring one-year compliance to antihypertension medication in the Seychelles.

OBJECTIVE: To examine the compliance to medication among newly diagnosed hypertensive patients screened from the general population of the Seychelles, a rapidly developing country. METHODS: Among the 1067 participants to a population-based survey for cardiovascular risk factors, hypertension was discovered in 50 (previously unaware of having hypertension and having blood pressure > or = 160/95 mmHg over 3 visits). These 50 patients were placed on a daily one-pill regimen of medication (bendrofluazide, atenolol, or a combination of hydrochlorothiazide and atenolol) and compliance to the regimen was assessed over 12 months using electronic pill containers. Satisfactory compliance was defined as taking the medication on 6 or 7 days a week on average (which corresponds to a mean compliance level of > or = 86%). FINDINGS: In the first month, fewer than half (46%) of the new hypertension patients achieved satisfactory compliance, and only about one-quarter (26%) achieved this level by the twelfth month. Compliance was better among the 23 participants who regularly attended medical follow-up, with nearly three-quarters of these patients (74%) achieving satisfactory compliance during the first month and over one-half (55%) by the twelfth month. There was a direct association between mean 12-month compliance level and having a highly skilled occupation; having good health awareness; and regularly attending medical appointments. In contrast, there was an inverse relationship between mean compliance level and heavy drinking. CONCLUSION: The low proportion of people selected from the general population who were capable of sustaining satisfactory compliance to antihypertension medication may correspond to the maximum effectiveness of medication interventions based on a screening and treatment strategy in the general population. The results stress the need for both high-risk and population approaches to improve hypertension control.
