Um estudo sobre hipertensão arterial sistêmica na cidade de Campo Grande, MS

Abstract

SummaryObjectives: To detect the actual prevalence of systemic hypertension in the city of Campo Grande, State of Mato Grosso do Sul, Brazil, and frequent risk factors.Methods: Cross-sectional study with a randomized sample of the adult population of the city of Campo Grande, MS, in a total of 892 individuals. A questionnaire on age, gender, level of education, smoking, alcohol consumption, and aspects of the treatment was applied. Anthropometric data (weight and height) were collected. According to the WHO, a BMI<25 kg/m² was considered normal weight; 25>BMI<30 overweight; and BMI> 30 obesity. Criteria for hypertension were based on the VII JNC report, with blood pressure cut-off values of 140 x 90 mmHg.Results: The prevalence of hypertension was 41.4%, varying with age (up to 29 years: 11.8%; 30-39: 24.8%; 40-49: 43.3%; 50-59: 42.4%; 60-69: 48.6% and > 70: 62.3%). A higher prevalence was observed among men (51.8%), whereas among women the prevalence was 33.1%.Individuals with basic level of education tended to present higher rates. Among overweight and obese individuals, a higher prevalence of hypertension was observed: normal BMI (27.9%), overweight (45.6%) and obesity (58.6%). Above 60 years of age, a higher percentage of isolated systolic hypertension was observed, with 16.4% (60-69 years) and 24.6% (>70 years). Daily or weekly alcohol consumption was also related to a higher incidence, of 63.2% and 47.2%, respectively. Only 59.7% were known to be hypertensive. Of the hypertensive individuals, 57.3% were undergoing some type of treatment. Of those undergoing regular treatment, 60.5% presented hypertension.Conclusion: The prevalence of hypertension was 41.4%, therefore higher than the average verified in some studies. This calls the attention for worsened epidemiologic conditions and cardiovascular repercussions, thus showing the need for higher public investment on education and orientation of these population groups as regards prevention.

Prevalência e fatores associados à pressão arterial elevada, seu conhecimento e tratamento em idosos no sul do Brasil

“…Estima-se que cerca de um terço dos hipertensos nunca teve o diagnóstico clínico da doença feito por um profissional de saúde 7 , e muitas vezes tomam ciência da doença apenas após um evento clínico grave decorrente de seu descontrole por vários anos 9 , tais como infarto agudo do miocárdio ou acidentes vasculares encefáli-cos 10,11 . Além disso, grande parte das pessoas que conhecem seu diagnóstico de HAS apresenta baixa aderência ao tratamento ou é tratada com terapêutica incorreta 10,12 .…”

“…Estudos de base populacional foram realizados para investigar a prevalência e os fatores associados à HAS na população brasileira, no entanto expressiva parte foi direcionada a adultos, adolescentes e crianças 5,9,12,13,14 . As pesquisas com idosos restringiram-se à região sudeste do país 5,7,15 18 .…”

Prevalência de hipertensão arterial em Adventistas do Sétimo Dia da capital e do interior paulista

“…It is worth noting the lower prevalence in the São Paulo state capital, because it was believed that the high exposure to stressors and the greater possibility of inadequate life styles and habits, characteristic of large cities, could contribute to a higher prevalence of hypertension. Brazilian studies have reported a higher prevalence of hypertension in large cities, such as the capitals of the states of Goiás (36.4%) 9 and Mato Grosso do Sul (41.4%) 10 and Brasília (37.9%) 11 , as compared with that of smaller cities, such as Sinop in the inner Mato Grosso state (23,2%) 12 , São José do Rio Preto i n the inner São Paulo state (25.2%) 13 , and Luzerna in the inner Santa Catarina state (14,7%) 14 .…”
