Prevalence of systemic hypertension in students aged 7 to 14 years in the municipality of Barbacena, in the State of Minas Gerais, in 1999

Abstract

OBJECTIVE: To detect the prevalence of systemic hypertension in children and to establish the relation between blood pressure levels and sex, age, ethnicity, weight, and height. METHODS: The prevalence of systemic hypertension and its relation to sex, age, ethnicity, weight, and height were studied in 611 students aged 7 to 14 years out of 19.928 students classified according to age, ethnicity, and sex, who underwent anthropometric evaluation and blood pressure measurement. Hypertensive individuals were considered those whose blood pressure level was > the 95th percentile for age and sex, confirmed on 3 examinations. RESULTS: The prevalence of hypertension was 16.6% in the first evaluation, and 4.6% and 2.5% in the subsequent evaluations. The mean blood pressure levels increased with age. Weight was important, not only to determine blood pressure in healthy children, but also to determine systemic hypertension in children, which was not observed with height despite the different studies. The prevalence of systemic hypertension in the different ethnic groups and the mean blood pressure levels according to sex were similar. CONCLUSION: In addition to routine physical examinations, age, weight, and appropriate cuff size should be considered when assessing blood pressure in children to prevent hypertension, morbidity and mortality, and to avoid placing a financial burden on health care providers

Prevalência de hipertensão e sua associação com excesso de peso e atividade física em adolescentes

“…Assim, considera-se que essa desigualdade de dados possa ser justificada pela diferença nas metodologias empregadas no diagnóstico da HA 4 , visto que os estudos que relataram maiores taxas de prevalência da HA tenderam a utilizar um menor número de aferições e intervalos mais curtos entre as coletas 5,22 . Por outro lado, estudos 23,24 que utilizaram três medidas com intervalo de 10 minutos entre as medições relataram taxas de prevalência próximas a 2%, corroborando os resultados do presente estudo, que verificou taxa de 1% com IC95% 0,21-2,89. Dessa forma, além dos fatores supracitados, o fato do adolescente se acostumar com o procedimento de mensuração e ficar mais calmo na coleta também pode ter influenciado os valores encontrados 3 .…”

Prevalence of non-communicable diseases in Brazilian children: follow-up at school age of two Brazilian birth cohorts of the 1990's

“…International data show that the prevalence of hypertension ranged from 2.2% to 4.5% [55,56], The prevalence of hypertension in SL was similar to those observed in those studies, while in RP the prevalence was higher. In studies conducted in Brazil, the prevalence of hypertension ranged from 2.5% to 9.4% [57,58]. …”

Influência do índice de massa corporal e da circunferência abdominal na pressão arterial sistêmica de crianças

“…A prevalência de hipertensão na infância, relatada em diversos estudos nacionais e internacionais, varia amplamente de 1,2 a 13%, dependendo, sobretudo, da metodologia empregada, da faixa etária estudada e do número de medidas aferidas (12)(13)(14)(15)(16)(17)(18) . Em Maceió (AL), utilizando-se duas aferições de pressão arterial em 1.253 alunos, 9,4% deles apresentavam PA acima do percentil 95 (16) .…”
