“…In the same population, we have also found that the prevalence of high blood pressure was higher, although not significantly, in girls than in boys. Systolic blood pressure showed a positive correlation with increased age among Age (years) Figure 2) Age-specific percentiles (fifth, 10th, 25th, 50th, 75th, 90th and 95th percentiles in ascending order) of diastolic blood pressure measurements in urban school children in Sousse, Tunisia boys, consistent with findings reported by several other studies of children (26)(27)(28). The negative correlation found between systolic blood pressure and age among girls could be explained by the hormonal modifications related to puberty, which starts earlier among girls than among boys.…”

“…Higher incidence of hypertension in men in our study was primarily driven by the 12.7 mmHg difference of SBP values between genders, which is in accordance with data from other studies [11, 16, 19]. …”

“…It is worth mentioning that a similar, relatively high incidence of hypertension in adolescents, especially males (6.8-23%, compared to 1.5-6% in females), was reported by authors from other European countries [11, 14, 16] and former Polish studies [17, 18], although the last two presented some methodological drawbacks.…”

IntroductionChildhood hypertension is defined based on the normative distribution of blood pressure (BP), but from the age of 18 years high BP is diagnosed using adult criteria. We compared the rates of diagnosis of hypertension in a group of 18-year-old subjects using BP percentiles and the adult criteria.Material and methodsBlood pressure was measured by registered nurses in 1472 18-year-old high-school students (780 men and 692 women). Also weight, height and waist circumference were recorded.ResultsThe prevalence of hypertension was 9% (16.2% in men and 0.9% in women, p < 0.001) using adult cut-off values and 14.7% (21.9% in men and 6.6% in women, p < 0.001) using percentile charts. Obesity was diagnosed in 2.4% and overweight in 13% of subjects, respectively. The relative risk ratio of diagnosing hypertension according to the adult criteria in overweight or obese subjects was 2.94 (95% CI 2.25-3.86) in men and 6.44 (95% CI 3.51-11.82) in women.ConclusionsOur study indicates high prevalence of hypertension in 18-year-old students – especially in men – and the importance of obesity as a risk factor of hypertension. The use of percentile charts instead of adult cut-off values increases the prevalence of hypertension in men by 35% from 16.2% to 21.9% and in women more than 7 times, i.e. from 0.9% to 6.6%. It seems reasonable to use higher (i.e. 98th) percentile values for definition of high blood pressure.

Representative Study for the Evaluation of Age- and Gender-Specific Anthropometric Parameters and Blood Pressure in an Adolescent Hungarian Population

Backgrounds/Aims: To assess the age- and gender-specific anthropometric parameters and blood pressure in Hungarian adolescents. Methods: A cross-sectional study was performed between 1997and 2000. Altogether 6,345 secondary school students (aged 15–18 years) were involved in the study. The representative sampling sites were selected randomly. In the capital city 3-stage and in the counties 4-stage stratified groups were assigned for the studies. Statistical analysis was performed using SPSS for Windows 9.0. Results: The age- and gender-specific percentile distributions are given with regard to body weight, body height, body mass index (BMI), waist circumference, waist-to-hip ratio and arterial blood pressure values. Elevated blood pressure values were found at the first recording in 14.1% of the boys and in 2.5% of the girls. Since it is well known that the arterial blood pressure (ABP) may exhibit considerable intra- individual fluctuation with time, we therefore categorized normotensive and hypertensive students on the basis of the mean ABP values calculated from data obtained during the course of the three separate consecutive measurement periods at least 2 weeks apart. After that, the incidence of high blood pressure was 7.5% in boys and 1.1% in girls. Conclusion: The age- and gender-specific cutoff values thus formed may serve as reference values to assess the risk of developing nutrition-related noninfectious diseases in the future on the basis of the present percentile distribution of BMI. The present study also provides data on the prevalence of hypertension in the 15- to 18-year-old age group.

Cardiovascular risk factor levels in Portuguese students

Abstract: The prevalence of cardiovascular risk factors is high among young male Portuguese students and preventive measures should be applied, namely regarding obesity.
