Relationship between alcohol consumption and control of hypertension among elderly Greeks. The Nemea primary care study

BACKGROUND

The aim of this study was to evaluate the significance of alcohol intake in relation to blood pressure control in treated subjects and to determine if there is a causative link between alcohol and inadequate control of hypertension.

METHODS

Our study population comprised 637 elderly individuals who reside in Nemea and in four other villages located in Corinthia, Peloponnesus, of which 615 were included in the analysis. The average age was 73.5±6.15 years. A special epidemiological questionnaire was completed by each participant and the blood pressure (BP) was measured according to a predefined protocol. Odds ratios were calculated and adjusted for potential confounders.

RESULTS

The overall prevalence of hypertension was 69.1%, 70.7% in men and 67.0% in women. In total, 11% of the hypertensives were not aware of having hypertension. Of those who were aware of having hypertension 91.0% were being treated. Among treated hypertensives 49.1% had systolic BP<140 mmHg and diastolic BP<90 mmHg. Only heavy drinking (>300 g/week) was found to be related with hypertension control.

CONCLUSIONS

Our study showed that the level of control among the elderly, in a Greek population, is positively associated with alcohol intake only for heavy drinking. The role of alcohol consumption in hypertension in the elderly needs further investigation.

Poor hypertension control in Greek patients with diabetes in rural areas. The VANK study in primary care

INTRODUCTION

This study aimed to determine hypertension prevalence and levels of awareness, treatment and control of hypertension among diabetic patients using data from the VANK study.

METHODS

The sample consisted of 221 men and women (122/99) diagnosed with type 2 diabetes. Semi-structured interviews were conducted with all participants. Controlled hypertension definition was based on having a systolic blood pressure (BP) of <130 mmHg and diastolic BP of <85 mmHg in subjects taking antihypertensive medications.

RESULTS

The mean +/- SD BP was 141.6 +/- 17.4 mmHg and 81.2 +/- 9.4 mmHg for systolic and diastolic BPs, respectively. Systolic and diastolic BP was higher in men than in women. The overall prevalence of hypertension was 194/221 (87.7%). In total, 34.1% of patients (66/194) were not aware of having hypertension. Of those who were aware of having hypertension (n = 128, 65.9%), all were treated. Among those treated, only 11 persons (11/194, 5.6%) had systolic BP <130 mmHg and diastolic BP <85 mmHg. Sixty-two (38.7%) had systolic BP <140 mmHg and diastolic BP <90 mmHg.

CONCLUSION

Although all of the diagnosed hypertensive patients (n = 128) received antihypertensive drug therapy, in only 8.6% (11/128) the treatment was effective (BP <130/85 mmHg). Translating our findings into clinical practice, there is a need for aggressive treatment of hypertension from primary care physicians, as well as regular surveillance to detect developing hypertension in diabetic patients.
