Prevalence of hypertension in a sample of Polish population - baseline assessment from the prospective cohort 'PONS' study.

OBJECTIVE: The aim of this cohort study was to evaluate the prevalence of hypertension and cardiovascular risk factors in the studied population. METHODS: Presented results are a part of the Polish-Norwegian Study (PONS) project. The study group consisted of 3,862 inhabitants of Swietokrzyskie Province aged 45-64 years (2,572 females and 1,290 males). RESULTS: Prevalence, awareness and control of hypertension was evaluated in the studied population of 3,854 urban and rural inhabitants. Mean blood pressure in the whole studied population was 139.6/81.9 mmHg; of the studied population 61.7% were hypertensive. Hypertension was more prevalent in the studied males (70.63%) than in the females (57.24%). In both males and females, the older subgroups (55-64 y.o.) had significantly higher blood pressure than the younger subgroups (45-54). Education had a significant impact on the prevalence of hypertension, and the highest prevalence of hypertension was observed in the middle level educated groups of females and males. No significant difference was observed between rural and urban inhabitants. In both females and males, the prevalence of hypertension significantly decreased with level of education. Hypertension was well-controlled in only 13.8% of the subjects. More studied females than males achieved good control of blood pressure (14.09 vs. 12.7%), and better control of blood pressure was significantly more frequent in better those who were better educated. Hypertension was not diagnosed in 23.2% of studied population. Significantly, more males than females had undiagnosed hypertension (30.4 vs. 19.5%). No significant difference between rural and urban populations was observed. Interestingly, both in females and males, the better educated groups had more undiagnosed hypertension than those who were well-educated. CONCLUSIONS: The studied group had a high prevalence of hypertension (61.7%), which was less frequent and better controlled in the studied females than in the males. No significant difference was observed between the urban and rural populations. Level of education had significant impact on the prevalence of hypertension.

Prevalence of diabetes mellitus and IFG in the prospective cohort 'PONS' study - baseline assessment.

OBJECTIVE: The aim of this cross-sectional study was to assess the prevalence of diabetes mellitus and impaired fasting glucose (IFG) in the Polish-Norwegian Study (PONS) population in Poland. METHODS: The presented results are part of the PONS project, and cover information from 3,854 people aged 45-64 (2,567 females and 1,287 males) who are inhabitants of Swietokrzyski Province. RESULTS: In the study group there were 62.8% participants with normoglycaemia, 28.9% participants with IFG and 8.4% participants with diabetes. In those with diabetes, there were 95 participants (2.5%) whose diabetes was unknown prior to this study. Among 5.9% patients with known diabetes 52.9% of the participants had a fasting blood glucose level of ≥ 126 mg%. There were 46.8% males and 70.8% females with normoglycaemia, 41.0% males and 22.8% females with IFG, and 12.2% males and 6.4% females with diabetes. The prevalence of diabetes was higher in participants in the older age group (55-64) compared to younger participants (45-54). The prevalence of diabetes decreased with increasing education and was higher among overweight or obese participants compared to normal weight participants. CONCLUSION: The prevalence of diabetes mellitus in study population was generally high, but especially high in males, and the awareness of diabetes in the population was generally low. Among participants with known diabetes more than half was not well controlled.

Prevalence of obesity - baseline assessment in the prospective cohort 'PONS' study.

OBJECTIVE: The aim of the study was to evaluate the prevalence of overweight and obesity in the population of Swietokrzyskie Province in Poland. METHODS: Body mass index (BMI), waist to hip ratio (WHR) and waist circumference (WC) in the Polish-Norwegian Study (PONS) was measured in 2,567 females and 1,287 males. Anthropometric measurements included fat mass, height, weight, waist and hip circumference. BMI and WHR were calculated. RESULTS: Data showed that 52% of males and 42% of females were overweight (25.0 ≤ BMI<30.0 kg/m2), and the prevalence of obesity (BMI ≥ 30.0 kg/m2) was 35% in both genders. The average BMI was higher in males (28.5 kg/m2) than in females (28.2 kg/m2). Analysis of WC showed that 36% of males and 45% of females had abdominal obesity, whereas measurements of WHR showed abdominal obesity in 64% of males and 79% of females. Generally, the prevalence of obesity was higher in the older age group (55-64 years) and in rural inhabitants. The prevalence of overweight increased with educational level, but the prevalence of obesity decreased with level of education in both males and females. CONCLUSIONS: Almost 80% of the PONS population were either overweight or obese; therefore, the PONS population is at increased risk of developing obesity-related diseases.
