Prevalência de excesso de peso e obesidade e fatores associados, Brasil, 2006

Abstract

OBJECTIVE:To estimate the prevalence of overweight and obesity and factors associated. METHODS:The study analyzed data referring to individuals aged 18 years or older interviewed through the system Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (VIGITEL -Telephone-based surveillance of risk and protective factors for chronic diseases), carried out in the Brazilian capitals and Federal District in 2006. For 49,395 individuals, the body mass index (BMI) was used to identify overweight (BMI ≥ 25 kg/ m 2 ) and obesity (BMI ≥30 kg/m 2 ). Prevalence and prevalence ratios were presented according to sociodemographic variables, level of schooling, health condition/comorbidities, and self-evaluation of health, stratifi ed by sex. Poisson regression was employed for crude and age-adjusted analyses. RESULTS:The prevalence of overweight was of 47% for men and 39% for women, obesity was around 11% for both sexes. Direct association was observed between overweight and level of schooling among men and inverse association among women. Obesity was more frequent among men living with a partner and was associated neither with level of schooling nor skin color. The prevalence of overweight and obesity was higher among black women and women who lived with a partner. The presence of diabetes, systemic arterial hypertension and dyslipidemias, as well as the subject perceiving his/her health as regular or poor, were also reported by the interviewees with overweight or obesity. CONCLUSIONS:While approximately one out of every two interviewees was classifi ed as being overweight, obesity was reported by one out of every ten interviewed subjects. Socioeconomic and demographic variables, as well as reported morbidities, were associated with overweight and obesity. These results were similar to the ones found in other Brazilian studies.

Variação temporal na prevalência do excesso de peso e obesidade em adultos: Brasil, 2006 a 2009

“…In this case, overweight was more prevalent among men (47%) than among women (39%), in 2006 11 , and this difference continued until 2009. However, the obesity prevalence rate was not different between men and women in 2006 (11%) 11 , and there was also no difference in obesity prevalence rates for between men and women in 2009 (14%).…”

“…It is also important to observe that the results in this study, especially in relation to which suggests that BMI is underestimated in reports by women, whereas it is reliable when it comes to men. While differences in overweight and obesity prevalence rates for men and women are presented in Brazilian studies which measure weight and height, the same does not occur when such information is reported by the participants 11 . In this case, overweight was more prevalent among men (47%) than among women (39%), in 2006 11 , and this difference continued until 2009.…”

“…In 2006, VIGITEL data showed that overweight and obesity prevalence rates were higher among black and brown women when compared to the white ones 11 , while data from a telephone survey conducted in the United States (which was an example to studies conducted by VIGITEL) also showed such difference 16 . An increasing trend in prevalence rates regarding the black and Mexican population living in the United States has also been observed from a period of six 12 to ten years 13 .…”

Excesso de peso: determinantes sociodemográficos e comportamentais em adultos, Brasil, 2008

“…Semelhante ao encontrado por Gigante et al 9 em estudo realizado nas capitais de estados brasileiros e no Distrito Federal em 2006, que apontou 47% de excesso de peso entre os homens e 39% entre as mulheres, nesta pesquisa a prevalência de excesso de peso foi maior entre os homens (49,6%), quando comparados às mulheres (39,7%). Sichieri & Moura 8 mostraram que a média do IMC nas 26 capitais brasileiras e Distrito Federal foi igual a 25,31kg/m² para os homens e 24,55kg/m² para as mulheres, sendo as médias de IMC sempre maiores para os homens quando em comparação com as mulheres.…”

“…Estudos apontam associação entre excesso de peso e alguns fatores sociodemográficos, como escolaridade, raça/cor, união conjugal 9 , idade e renda 10 , mesmo que algumas dessas associações sejam divergentes entre os sexos.…”
