RESUMO

BACKGROUND: Hypertension is an important risk factor for cardiovascular disease; however, limited findings are available on its detection and management in rural Australia. AIM: To assess the prevalence, awareness and treatment of hypertension in a rural South-East Australian population. METHODS: Three cross-sectional surveys in Limestone Coast, Corangamite Shire and Wimmera regions during 2004-2006 using a random population sample (n = 3320, participation rate 49%) aged 25-74 years. Blood pressure was measured by trained nurses. Information on history of hypertension and medication was obtained by questionnaires. Hypertension was defined as systolic blood pressure >or=140 mmHg and/or diastolic blood pressure >or=90 mmHg and/or on antihypertensive drug treatment. RESULTS: Overall, one-third of participants had hypertension; of these, two-thirds, 54% (95% confidence interval (CI) 47-60) of men and 71% (95% CI 65-77) of women, were aware of their condition. Half of the participants with hypertension were treated and nearly half of these were controlled. Both treatment and control were more common in women (60%, 95% CI 54-67 and 55%, 95% CI 47-64) compared with men (42%, 95% CI 36-49 and 35%, 95% CI 26-44). Monotherapy was used by 55% (95% CI 48-61) of treated hypertensives. Angiotensin-converting enzyme inhibitors were the most frequently used class of antihypertensive drugs in men, whereas angiotensin-converting enzyme inhibitors, angiotensin receptor antagonists and diuretics were all widely used among women. CONCLUSION: This study emphasizes suboptimal detection and treatment of hypertension, especially in men, in rural Australia.

RESUMO

AIMS/HYPOTHESIS: The aim of this study was to investigate whether the use of antimicrobials is associated with the risk of childhood type 1 diabetes. MATERIALS AND METHODS: The study population included all children born in Finland between 1996 and 2000 who were diagnosed with type 1 diabetes by the end of 2002. For each case (n=437), four matched controls were selected. Data on diabetes and the maternal use of antimicrobials was derived from nationwide registries. RESULTS: Maternal use of phenoxymethyl penicillins (odds ratio [OR]=1.70, 95% CI 1.08-2.68, p=0.022) or quinolone antimicrobials (OR=2.43, 95% CI 1.16-5.10, p=0.019) before pregnancy was associated with an increased risk of type 1 diabetes in the child, whereas the use of other specific antimicrobials was not related to the risk. The risk was also higher among mother-child pairs where macrolides were used both by the mother before pregnancy and by the child, compared with pairs where neither used macrolides (OR=1.76, 95% CI 1.05-2.94, p=0.032). Maternal use of antimicrobials during pregnancy was not associated with an increased risk. The high use of antimicrobials by the child (more than seven vs seven or less purchases) was related to greater risk (OR=1.66, 95% CI 1.24-2.24, p=0.001). CONCLUSIONS/INTERPRETATION: Overall, the use of antimicrobials before pregnancy, during pregnancy or during childhood was not related to the risk of childhood type 1 diabetes. However, the use of some specific antimicrobials by the mother before pregnancy and by the child may be associated with an increased risk. Further studies are needed to confirm these associations and to elucidate the underlying mechanisms of action.

RESUMO

BACKGROUND: The lignan enterolactone, which is produced by the intestinal microflora from dietary precursors, may protect against hormone-dependent cancers and cardiovascular diseases. OBJECTIVE: We examined the cross-sectional associations between the serum enterolactone concentration and variables related to diet and health in Finnish adults. DESIGN: Serum enterolactone was measured by using time-resolved fluoroimmunoassay in 2380 Finnish men and women aged 25-64 y who were participating in a cross-sectional national survey in 1997. Background information was collected with self-administered questionnaires and the diet was assessed with a food-frequency questionnaire. RESULTS: The median serum enterolactone concentration was 13.8 nmol/L (range: 0-95.6 nmol/L) in men and 16.6 nmol/L (range: 0-182.6 nmol/L) in women. Multiple regression analyses showed positive associations in men between the serum enterolactone concentration and constipation, consumption of whole-grain products, and intake of fruit and berries. In women, the serum enterolactone concentration was positively and independently associated with consumption of vegetables, subject age, and constipation and was negatively associated with smoking. Furthermore, female subjects of normal weight had significantly higher serum enterolactone concentrations than did their underweight or obese peers. CONCLUSIONS: The serum enterolactone concentration varies widely in the population. Of the variables we examined, the most important determinants of the serum enterolactone concentration were consumption of lignan-containing foods and constipation; however, these appeared to explain only a small part of the variation. Therefore, the role of gut microflora in the metabolism of lignans might be very important. Further studies will also be needed to determine the bioavailability and absorption rate of lignans.
