Abstract

Resumen Introducción El objetivo de este trabajo fue describir la prevalencia y los factores asociados a la obesidad abdominal de adultos de 20 a 59 años del Estado de Pernambuco, Brasil. Material y Métodos Estudio epidemiológico de corte transversal con una muestra representativa de la población adulta de áreas urbanas y rurales de este estado brasileño (1.496 personas). La circunferencia de la cintura (CC) fue utilizada como indicador de riesgo de enfermedad cardiovascular y predictor de la obesidad abdominal. Resultados La prevalencia de obesidad abdominal en los adultos del Estado de Pernambuco fue de 64,4%. Al realizar los análisis por sexo se encontró una prevalencia de obesidad abdominal de 37,7% (IC: 33,4-42,1) en hombres y 80,7% (IC: 78,1-83,1) en las mujeres respectivamente. En el análisis multivariable ajustado para el sexo masculino mantuvieron asociación con la obesidad abdominal las variables: edad y trabajo formal y en relación a las mujeres se encontró asociación con edad, escolaridad y menopausia. Conclusiones Alta prevalencia de obesidad abdominal en la población adulta de la región Nordeste de Brasil, asociada a algunos factores de tipo social y biológicos, reflejan la necesidad de mayor planificación e implementación de estrategias intersectoriales vinculadas al control y prevención de este importante problema nutricional.

Abstract Introduction The objective of this project was to describe the prevalence and factors associated with abdominal obesity in adults aged 20 to 59 in the State of Pernambuco, Brazil. Material and Methods This is a cross-sectional epidemiological study with a representative sample of the adult population of urban and rural areas of the State of Pernambuco, Brazil (1,496 people). The circumference of the waist (CC) was used as an indicator of cardiovascular disease risk and predictor of abdominal obesity. Results The prevalence of abdominal obesity in adults of the State of Pernambuco was 64.4% of which 37.7% (IC: 33.4-42.1) corresponds to men and 80.7% (IC: 78.1-83.1) in women. In the multivariate analysis adjusted for the male sex, variables such as age and formal work were associated with abdominal obesity. With regard to women: age, schooling and being in climacteric. Conclusions High prevalence of abdominal obesity in the adult population of the Northeast region of Brazil, associated with some social and biological factors, reflect the need for greater planning and implementation of intersectoral strategies linked to the control and prevention of this important nutritional problem.

Prevalence of overweight, obesity, abdominal obesity and obesity-related risk factors in southern China

Lihua Hu, Xiao Huang, Chunjiao You … (2017)

Objectives The purpose of this study is to assess the prevalence of overweight/obesity, abdominal obesity and obesity-related risk factors in southern China. Methods A cross-sectional survey of 15,364 participants aged 15 years and older was conducted from November 2013 to August 2014 in Jiangxi Province, China, using questionnaire forms and physical measurements. The physical measurements included body height, weight, waist circumference (WC), body fat percentage (BFP) and visceral adipose index (VAI). Multivariate logistic regression analysis was performed to evaluate the risk factors for overweight/obesity and abdominal obesity. Results The prevalence of overweight was 25.8% (25.9% in males and 25.7% in females), while that of obesity was 7.9% (8.4% in males and 7.6% in females). The prevalence of abdominal obesity was 10.2% (8.6% in males and 11.3% in females). The prevalence of overweight/obesity was 37.1% in urban residents and 30.2% in rural residents, and this difference was significant (P < 0.001). Urban residents had a significantly higher prevalence of abdominal obesity than rural residents (11.6% vs 8.7%, P < 0.001). Among the participants with an underweight/normal body mass index (BMI), 1.3% still had abdominal obesity, 16.1% had a high BFP and 1.0% had a high VAI. Moreover, among obese participants, 9.7% had a low /normal WC, 0.8% had a normal BFP and 15.9% had a normal VAI. Meanwhile, the partial correlation analysis indicated that the correlation coefficients between VAI and BMI, VAI and WC, and BMI and WC were 0.700, 0.666, and 0.721, respectively. A multivariate logistic regression analysis indicated that being female and having a high BFP and a high VAI were significantly associated with an increased risk of overweight/obesity and abdominal obesity. In addition, living in an urban area and older age correlated with overweight/obesity. Conclusion This study revealed that obesity and abdominal obesity, which differed by gender and age, are epidemic in southern China. Moreover, there was a very high, significant, positive correlation between WC, BMI and VAI. However, further studies are needed to explore which indicator of body fat could be used as the best marker to indirectly reflect cardiometabolic risk.
