Obesidade adulta nas nações: uma análise via modelos de regressão beta

Abstract

Obesity is considered a serious public health problem, as an epidemic disease with major global repercussions that is associated with the development of other chronic conditions such as hypertension, diabetes, and cardiovascular diseases. The current study examines the distribution of adult obesity in different countries using a beta regression model. This is a descriptive ecological study with a quantitative and inferential approach and a focus on beta regression analysis. Application of this method used a set of real data from public sources on adult obesity in 78 countries in 2014. Descriptive data analysis showed that 50% of the countries showed adult obesity prevalence greater than 20%. In addition, analysis of the distribution of prevalence by country showed lower adult obesity levels in countries of Asia and Africa. Meanwhile, higher values were found in countries of the Americas and Europe. Boxplot analysis also evidenced a possible difference in the proportion of obese adults between the Americas and Europe on one side and Africa and Asia on the other. Adjustment of the beta regression model with varying dispersion and 5% significance identified mean annual per capita alcohol intake, percentage of insufficient physical activity, percentage of the population living in urban areas, and life expectancy as variables associated with adult obesity.

Nutritional status and living conditions of adults and older people in quilombola communities, municipality of Santarem, Para - Amazon, Brazil

“…51 Chronic non-communicable diseases represent a serious public health problem, as they are pointed out as the main causes of deaths in the world, constituting a disease with great social, family and financial impact, especially for the families of affected people, since the treatments offered represent huge expenditures in the health sector. 52 However, we cannot forget all these diseases are also influenced by socioeconomic factors, difficulties in accessing health services and inadequate health care. Situations of social vulnerability and health have been related to the ethnic-racial issue, showing inequalities in the profiles of illness and death in populations that declare their skin colour like black and brown.…”

Abdominal obesity and association with sociodemographic, behavioral and clinical data in climacteric women assisted in primary care

“…This important life stage starts when the woman is approximately 40 years old and lasts until the age of 60–65 years. It is characterized by hormonal changes and functional, morphological, psychogenic and physical modifications [ 3 ]. It is believed that, of life’s several phases, the climacteric is the one that causes the greatest impact on the woman’s health [ 4 ].…”

“…Among different changes that affect the health of the climacteric woman, obesity occupies a prominent position. This pathology has a complex and multifactorial etiology with an epidemic character [ 5 ] and is considered a severe public health problem worldwide [ 3 ]. In Brazil, data from the Surveillance System of Risk and Protection Factors for Chronic Diseases by Telephone Survey (VIGITEL) of the year of 2017 showed that overweight was present in 50.5% of the women, increasing as age increases up to 64 years [ 6 ].…”

“…S. Souza и соавт. [5] отмечают, что в 50% стран мира распространенность ожирения среди взрослых превышает 20%. Кроме того, анализ распределения распространенности ожирения по странам продемонстрировал более низкий уровень ожирения среди взрослых в странах Азии и Африки.…”

“…Кроме того, анализ распределения распространенности ожирения по странам продемонстрировал более низкий уровень ожирения среди взрослых в странах Азии и Африки. Между тем, более высокие значения были обнаружены в странах Северной и Южной Америки и Европы [5].…”
