Características sociodemográficas como factores de riesgo para la obesidad y el sobrepeso en la población adulta española

Prevalence of overweight, obesity and central obesity and factors associated with BMI in indigenous yaqui people: a probabilistic cross-sectional survey

BACKGROUND

The Yaquis are an Indigenous group who inhabit in the state of Sonora in northwestern Mexico. This group has experienced changes in their lifestyle, moving from a traditional lifestyle to a more modern one, resulting in an increase of obesity and its comorbidities. However, few studies have been done in this group. The aim of this study was to determine the prevalence of overweight, obesity and central obesity and to identify the factors associated with body mass index (BMI) in a representative sample of Indigenous Yaqui people from Sonora, Mexico.

METHODS

A cross-sectional survey with multistage sampling was conducted among adults (N = 351) with residence in Yaqui traditional villages (Vícam, Pótam, Loma de Guamúchil, Loma de Bácum, Tórim, Ráhum, Huiribis or Belem). Anthropometric measurements were taken to diagnose overweight, obesity and central obesity. Food frequency and physical activity (PA) questionnaires designed for the Yaqui population were applied, as well as sociodemographic and clinical history questionnaires. The factors associated with BMI were assessed using multiple linear regression considering the complex design of the sampling.

RESULTS

The prevalence of overweight, obesity and central obesity in the population were 36.5%, 35.0% and 76.0%, respectively. Having higher values of the modernization index (β = 0.20, p = 0.049) was associated with a higher BMI, while having a higher consumption of a "prudent" dietary pattern (traditional dishes, fruits, vegetables and low-fat dairy) (β = -0.58, p = 0.009) and performing a greater number of hours per week of vigorous PA (β = -0.14, p = 0.017) were associated with a lower BMI.

CONCLUSIONS

The prevalence of the studied abnormalities is high. The evidence presented in this study suggests that interventions are needed and more research is required to determine the appropriate components of such interventions, in order to meet the needs of the Yaqui people.

Relationships between work, lifestyles, and obesity: cross-sectional study based on the 2017 Spanish National Health Survey

AIMS

Overweight and obesity are affected by factors such as dietary transgressions and lack of exercise, as well as less obvious factors such as shift work and sedentary working. (i) To explore the associations between overweight and obesity (O/O) with working conditions such as type of job position, and work shifts; (ii) to know the associations between O/O with lifestyles (physical activity, eating habits, and tobacco and alcohol consumption).

METHODS AND RESULTS

A cross-sectional, population-based design was used based on the Spanish National Health Survey. The final sample consisted of 9097 workers aged between 18 and 65. The influence of the explanatory variables on the outcome variable (body mass index) was examined using logistic regression. The prevalence of O/O increased by 4% for every additional year of age (P < 0.001) and was 3.1 times more frequent among men (P < 0.001). It also was 20% higher in night work or rotating shifts (P < 0.01), and 14.9% lower in sedentary job positions (P < 0.05). Low consumption of the following foods was significantly associated with a reduction in O/O: meat (16.2%), fish (75.4%), cured meats (35.1%), dairy products (33.3%), and snacks (47.1%).

CONCLUSION

Age, men, engaging in moderate or low levels of physical activity, being an ex-smoker, working during the night or rotating shifts, holding a non-sedentary job position, having a low to moderate consumption of pasta, potatoes, and rice, a moderate consumption of bread and cereals, as well as dairy products, vegetables, sugary foods, and fast food, have been significantly associated with a higher prevalence of O/O. No relationships were identified between the consumption of alcohol, fruit, eggs, pulses, and sugary soft drinks.

Prevalence of obesity and associated cardiovascular risk factors in the Spanish population: the ENPE study

INTRODUCTION AND OBJECTIVES

Obesity is a significant public health problem associated with an increased risk of cardiovascular risk factors (CVRF). The aim of this study was to determine the prevalence of overweight and abdominal obesity (AO) in the Spanish population aged ≥ 3 years and to analyze the influence of sociodemographic and lifestyle factors and their association with CVRF.

METHODS

The sample was drawn from the ENPE study (n=6800). The study protocol included individual anthropometric measurements, sociodemographic factors, food intake (food frequency questionnaire), physical activity, lifestyles, and health problems.

RESULTS

The estimated overall prevalence of obesity (22.0%; 95%CI, 21.0-23.0) and AO (64.7%; 95%CI, 63.5-65.8) was higher in men, in persons aged ≥ 65 years, and in those with a lower socioeconomic level or from southern regions. Lifestyle pattern was significantly associated with obesity and AO (P=.011), which were less likely in people with an active lifestyle pattern (P <.0001). Obesity (OR, 1.85; 95%CI, 1.24-2.78) and AO (OR, 2.16; 95%CI, 1.1-4.24) were positively associated with CVRF. Clustering of CVRF with obesity and/or AO was higher in women (12.6%; 95%CI, 11.4-13.9) and in persons aged ≥ 65 years (32.7%; 95%CI, 30.0-35.4).

CONCLUSIONS

The prevalence of obesity and AO in the Spanish population is high; it is higher in men, increases with age, and is inversely related to socioeconomic status. A lifestyle pattern combining a higher level of physical activity, moderate sedentariness and a Mediterranean dietary pattern is associated with a lower probability of obesity, AO, and CVRF.

Personality Traits and Obesity

Objective: Previous studies investigating the association between body weight and personality traits have found mixed results. This paper uses a large data set and two different study designs (cross-sectional and longitudinal) to provide more consistent estimates of the effect of personality traits on obesity. Methods: The present study is based on data from the German Socio-Economic Panel (GSOEP) from the waves 2005 to 2013; GSOEP is a longitudinal survey of private households in Germany that has been carried out since 1984. Responses provided data about personality, measured using the BFI-S Questionnaire, data for self-rated body mass index BMI (to determine the obesity level), as well as information for potential confounders. Cross-sectional and longitudinal logistic regression models were used. Results: The cross-sectional study yielded statistically significant results for the association between the outcome variable and four personality factors neuroticism, extraversion, openness and agreeableness. After controlling for several potential confounders, the association between obesity and extraversion, openness as well as agreeableness remained; additionally, the personality factor consciousness reached statistical significance. In the longitudinal study, a statistically significant association was found only for two personality factors, namely extraversion and agreeableness. After adding the control variables, the FE-regression yielded an association only for agreeableness (negative). Gender differences were not significant. Discussion: The findings show that results of a cross-sectional study design differ from the outcome of the longitudinal study design. The latter stresses the association between excess weight and the personality factor agreeableness, contrasting with most outcomes of previous research.

Anthropometric Measures as Predictive Indicators of Metabolic Risk in a Population of "Holy Week Costaleros"

Preventive measures are a priority in those groups that perform intense physical efforts without physical preparation and that can also be overweight or obese. One of the groups that reflect these characteristics is the costaleros of the Holy Week of Andalusia, Spain. This paper aims to describe the effect of obesity on blood pressure. A descriptive cross-sectional study was conducted on 101 costaleros. The anthropometric measures were determined through segmental impedance. Cardiac recovery and anaerobic power were measured through the Ruffier⁻Dickson test and the Abalakov test, respectively. Blood pressure was measured when the individuals were at rest. The Kruskal⁻Wallis test was applied for of continuous parameters and the X² test for dichotomous measures. Binary logistic regression models were used for the subsequent analysis with R-square and Receiver Operating Characteristic (ROC) curves. The average population was 28 years of age, 173.7 cm tall, and 82.59 Kg weigh. The excess of body fat was 11.27 Kg and Body Mass Index was 27.33 Kg/m². 72.3% showed abnormal blood pressure and 68.2% were overweight. 32.7% had a waist-hip ratio higher than 0.94. The probability of presenting abnormal blood pressure was higher among the subjects whose fat content was higher and muscle content was lower.

Risk Factors Associated with Overweight and Obesity in Japanese-Brazilians

Objective

To estimate which risk factors (sociodemographic, lifestyle, and health conditions) are associated with overweight and obesity in Japanese-Brazilians.

Methods

This was a cross-sectional study carried out with Japanese-Brazilians living in the southern region of Brazil. Data were collected between March and December of 2016 through a household survey addressing sociodemographic characteristics, lifestyle, and health conditions. Data were analyzed by means of logistic regression considering 95% level of significance.

Results

A total of 542 Japanese-Brazilians with a mean age of 47.75 years were evaluated; 52.8% were eutrophic, 36.9% were overweight, and 10.3% were people with obesity. The following variables remained associated with overweight after adjustments; male gender (ORaj = 1.85, CI = 1.24-2.76), age range of 40-49 years (ORaj = 2.27, CI = 1.10-4.68), and 50 to 59 years (ORaj = 2.17, CI = 1.004-4.72), alcohol consumption (ORaj = 2.11, CI = 1.07-4.16), and presence of chronic disease (ORaj = 1.59, CI = 1.02-2.46). The following were independent factors associated with obesity: male gender (ORaj = 3.63, CI = 1.78-7.40), the presence of chronic disease (ORaj = 4.13, CI = 1.96-8.71), the age range of 30 to 39 years (ORaj = 4.74, CI = 1.65-13.64) and 40 to 49 years (ORaj = 2.89, CI = 1.05-7.95), and irregularly active lifestyle (ORaj = 2.73, CI = 1.12-6.69).

Conclusion

The results of this study show that being a male in the age range of 30-49 years old, alcohol consumption, and presence of chronic disease are associated with overweight and obesity in Japanese-Brazilians.

The impact of obesity on health-related quality of life in Spain

BACKGROUND

It is well documented that obesity is strongly associated with mortality and morbidity, but less is known about its impact on functional status and health-related quality of life (HRQOL). The purpose of this study was to calculate the impact of the Body Mass Index (BMI) on the HRQOL of the Spanish adult population, with special emphasis on BMI ≥ 35.

METHODS

We used the Spanish National Health Survey (SNHS) 2011-2012 to assess the statistical association between HRQOL, measured through the EuroQol-5D-5L questionnaire, and the BMI. We conducted linear regression analysis for the EuroQol-5D-5L Visual Analogue Scale (VAS) and probit regressions for each of the five dimensions of the EuroQol-5D-5L.

RESULTS

Self-perceived problems in the five dimensions of the EuroQol-5D-5L increased along the BMI, especially in the mobility and pain/discomfort dimensions. Having a BMI ≥ 35 reduced HRQOL even in the absence of chronic diseases. After controlling for comorbidities, severe obesity decreased the VAS score by an average of 1.9 points and increased the probability of reporting any HRQOL problem in mobility (11.8%), self-care (2.2%), usual activities (4.3%) and pain/discomfort (7.4%). No association was found between obesity and mental problems. All the parameters analysed suggest that HRQOL in women and people aged 65 years and over was significantly worse than average.

CONCLUSIONS

BMI is an explanatory factor of self-perceived quality of life. Obesity is associated with a worse HRQOL, especially in women and people aged over 64 years. These results may be useful for designing prevention or treatment health policies to target obesity among the Spanish population.
