Determinantes de risco para doenças cardiovasculares em escolares

Abstract

Original Article M a i l i n g A d d r e s s : E s t e l a m a r i s T . M o n e g o OBJECTIVETo investigate the occurrence and association of arterial hypertension with several lifestyle variables. METHODSTransversal population-based study with a random sample of students (7 to 14 years of age) of public and private schools. Variables investigated were nutritional status, blood pressure, and lifestyle (tobacco use, alcohol intake, physical activity and eating habits). RESULTSOut of the 3,169 schoolchildren assessed, 5.0% had arterial hypertension and 6.2% had normal-high blood pressure. Classifi cation by gender shows boys 6.4% and girls 6.0% with normal-high blood pressure, and boys 4.3% and girls 5.7% with arterial hypertension. Body mass index (BMI) measurements identifi ed 16.0% excess weight students, 4.9% of whom were obese. A signifi cant association (p = 0.01) between arterial hypertension and excess weight was observed. Among the students participating in the study, 11.6% did not attend physical education classes and 37.8% had sedentary leisure habits. Twenty students (0.6%) were smokers and 32.7% had already experimented with alcohol. None of these variables showed statistical signifi cance as to blood pressure values and nutritional status. CONCLUSIONIn light of the fi ndings in this study which show schoolchildren with a higher than expected frequency of mean blood pressure and BMI values, associated with a lifestyle that tends to favour the development of cardiovascular diseases, we felt led to propose interventional measures focused on the school as an agent of change and capable of conveying information to family units. This possibility encourages us to propose that schools be partners in promoting health. KEY WORDSPrevention and control, epidemiology, anthropometry, arterial blood pressure, student health

Excesso de peso e fatores associados em adolescentes de uma capital brasileira

“…The prevalence of OW was 21.2%, which indicates an important increase in relation to the prevalence found in a study conducted in the same city in 2006 by Monego and Jardim (16% of OW) 24 . The OW found in this investigation was similar to that reported in , and in international studies of South American countries 26,27 and in Asia 28 .…”

“…the same individuals who had higher levels in 1993 also had higher levels in 2008. However, cholesterol values were not As already suggested by Monego & Garden, when studying the determinants of cardiovascular disease risk in school-aged population 29 , these data can be used in strategies for early intervention on modifiable risk factors.…”

Physical activity in Brazil: a systematic review

“…In ten studies, the sample was school-based 16,17,18,19,20,21,22,23,24,25 and four included workers 26,27,28,29 . The sample size ranged from 160 individuals 30 to 54,369 8 , while the majority of the studies (38) included more than a thousand subjects, and only two included fewer than five hundred 30,31 .…”

“…In all, 20 studies included adolescents (10-17 years), of which tem included only this age bracket. Only two studies included children (7-9 years) in the sample 20,21 , neither of which exclusively.…”
