1417Geographical differentials and trends in obesity burden in Argentina: a socio-demographic approach

Abstract Background In Argentina, there is evidence suggesting the obesity prevalence follows a social gradient. We analyze geographical differentials and trends in obesity burden according to socio-demographic conditions in Argentina (2005-2013). Methods The geographical distribution (n = 24 provinces) of the obesity burden in adult population of Argentina in 2005, 2009, and 2013 was analyzed by using mapping techniques. The National Survey of Chronic Diseases Risk Factors datasets were used to estimate and map the age-standardized prevalence of obesity (ASPO) and group-specific prevalence (% obesity) by province and year. Population groups were defined according to socio-demographic factors: age, sex, income level, education, and poverty level (by unsatisfied basic needs –UBN). Results Most of the provinces had an increasing ASPO between 2005 and 2013. In 2013, 75% of the provinces showed an ASPO above 20% in men, while 50% of the provinces exceed this ASPO value in women. In both sexes, the middle-aged group presented the most unfavorable situation. Overall, all the socio-demographic groups considered showed growing trends in obesity prevalence, although there were geographical disparities. Among the middle-income level population, a marked rising change was observed from 2009 to 2013. The population with incomplete primary education presented higher prevalence for all the years studied compared to the population with university education. Conclusions Since 2005, there was an overall increase in obesity prevalence in Argentina, with persistence of geographical disparities according to socio-demographical conditions. Key messages An overall rising trend in obesity prevalence was observed in Argentina. Geographical disparities by social groups were observed.

Infant obesity has become one of the most serious global health challenges of our time. The combined prevalence of overweight and obesity has rapidly increased worldwide during the last two decades, especially in some developing countries where obesity is reaching levels on a par with some industrialized countries, or even higher. This fast growth has occurred especially in countries in the midst of rapid social-economic transitions. Most international comparisons focus on the adult population while analyses focusing on the child population are more limited. Using the methodology developed by Phillips and Sul [1], this paper studies the worldwide evolution of infant body mass index (BMI), overweight and obesity prevalence for a large sample of countries during the period 1975-2016. Our results indicate that the figures for BMI or the prevalence of obesity in different countries do not converge, while the opposite is the case for overweight prevalence in children. Furthermore, there is a non-linear relationship between obesity and income or human capital, indicating that low and middle-income countries require a strong initiative for health policies targeting obesity prevention.

AbstractThis study provides trends in obesity prevalence in adults from 2013 to 2016 in France. 63,582 men and women from independent samples upon inclusion from the Constances cohort were included. Anthropometrics were measured at Health Screening Centers and obesity defined as a Body mass index (BMI) ≥ 30 kg/m2; obesity classes according to BMI are as follows: class 1 [30–34.9]; class 2 [35–39.9]; class 3 [≥ 40 kg/m2]. Linear trends across obesity classes by sex and age groups were examined in regression models and percentage point change from 2013 to 2016 for each age category calculated. All analyses accounted for sample weights for non-response, age and sex-calibrated to the French population. Prevalence of obesity ranged from 14.2 to 15.2% and from 14 to 15.3% in women and men respectively from 2013 to 2016. Class 1 obesity category prevalence was the only one to increase significantly across survey years in both men and women (p for linear trend = 0.04 and 0.01 in women and men respectively). The only significant increase for obesity was observed in the age group 18–29 y in both women and men (+ 2.71% and + 3.26% point increase respectively, equivalent to an approximate rise of 50% in women and 93% in men, p = 0.03 and 0.02 respectively). After adjustment for survey non-response and for age and sex distribution, the results show that class 1 obesity prevalence has significantly increased in both women and men from 2013 to 2016, and only in young adults in a representative sample of the French population aged 18–69 years old.

Abstract Objective: To evaluate the potential impact of sugar-sweetened beverage (SSB) taxes on overweight and obesity prevalence in countries of different income classifications. Design: Systematic review following PRISMA guidelines (PROSPERO number CRD42020161612). Five databases (Cochrane Library, Embase, LILACS (via Virtual Health Library) and MEDLINE (via PubMed), and Web of Science were searched, from January 2009 up to December 2019. Articles that reported changes in purchases, sales, intake, body weight, BMI, overweight and/or obesity prevalence due to a tax on, or price change in SSBs were included. Setting: Studies conducted in countries of different income classifications. Participants: The search yielded 8,349 articles of which twenty-one met inclusion criteria. Results: Among the 16 studies selected, only 2 did not show that consumption, sales and purchase decreased as the price of SSBs increased. In 8 of the 13 studies selected, a positive effect of an SSB tax on decreasing overweight and obesity prevalence was expected. It is estimated that a 20% taxation on SSBs would result in a greater decrease in the prevalence of overweight and obesity compared to a 10% rate. Studies with no significant effect of taxing on sales, purchases, consumption and prevalence of obesity were from high-income countries, while significant effects of taxing on reducing purchase, consumption and/or obesity prevalence were found in studies from upper-middle and middle-income countries. Conclusion: A high SSB tax might be an effective fiscal policy to decrease purchase and consumption of SSBs and reduce overweight/obesity prevalence, especially if the tax were specific for beverage volume.

Prevalence Of Obesity

Obesity rates have increased markedly in Latin America, especially during the last 10-15 years, becoming a public health problem in most countries. Prevalence of obesity among preschool children remains low, while among schoolchildren it has increased considerably. Prevalence is high in the adult population, especially among women with less schooling. In developed populations, obesity occurs more frequently among the poor; the opposite occurs in less developed societies, where in households undergoing nutritional transition, underweight can coexist with obesity. The most important determinant factors involved in the increasing obesity prevalence are fetal and infant nutritional conditions (stunting), education and socioeconomic conditions, dietary changes (especially increased total energy intake), and physical inactivity. Because chronic diseases are the main causes of death in the Region and obesity is one of the main risk factors for these diseases, policies to improve economic and educational levels with the implementation of health promotion and prevention should be a priority in every country.

AbstractObjectiveLow- and middle-income countries are experiencing rises in the prevalence of adult obesity. Whether these increases disproportionately affect vulnerable subpopulations is unclear because most previous investigations were not nationally representative, were limited to women, or relied on self-reported anthropometric data which are subject to bias. The aim of the present study was to assess changes in the prevalence of obesity from 2005 to 2010 in Colombian adults; overall and by levels of sociodemographic characteristics.DesignTwo cross-sectional, nationally representative surveys.SettingColombia.SubjectsMen and women 18–64 years old (n 31 105 in 2005; n 81 115 in 2010).ResultsThe prevalence of obesity (BMI ≥30 kg/m2) was 13·9 % in 2005 and 16·4 % in 2010 (prevalence difference = 2·7 %; 95 % CI 1·9, 3·4 %). In multivariable analyses, obesity was positively associated with female sex, age, wealth, and living in the Pacific or National Territories regions in each year. In 2010, obesity was also associated with living in an urban area. The change in the prevalence of obesity from 2005 to 2010 varied significantly according to wealth; 5·0 % (95 % CI 3·3, 6·7 %) among the poorest and 0·3 % (95 % CI −1·6, 2·2 %) in the wealthiest (P, test for interaction = 0·007), after adjustment. Obesity rates also increased faster in older than younger people (P, test for interaction = 0·01), among people from urban compared with non-urban areas (P, test for interaction = 0·06) and in adults living in the Atlantic region compared with others.ConclusionsAdult obesity prevalence has increased in Colombia and its burden is shifting towards the poor and urban populations.

AbstractObjectiveThe rapid increase in obesity rates over recent years suggest that cultural and societal influences are affecting the adjustment in the energy balance equation in addition to other physiopathological or genetic determinants. Therefore, a pan-EU study was carried out to explore the influence of sociodemographic factors as well as some attitudes (smoking and exercise) on the prevalence of obesity in the adult population of all 15 member states of the EU.DesignOverall, a sample of 15 239 individuals aged 15 years and upwards in the EU completed the questionnaire. Subject selection was quota-controlled to make the sample nationally representative following a multistage stratified cluster sampling. Self-reported height and weight were used to calculate body mass index (BMI).ResultsFrom the EU average results, it can be seen that only about half of the EU population (48%) is within the normal weight range, while the obesity (BMI > ≥ 30 kg m−2) prevalence was about 10% in the EU and the overweight prevalence was 36.6% and 25.6% among men and women, respectively. UK subjects had the highest prevalence of obesity (12%), while Italians, French and Swedes had the lowest levels of obesity (about 7%). Concerning age and social class interactions, logistic regression analysis showed that high social class and younger individuals in all groups had a lower odds ratio for obesity prevalence. People with a higher level of education are less likely to be obese, while the interaction between educational levels and obesity was different for men and women. A low participation in various leisure-time physical activities, the lack of interest (precontemplation) in being involved in exercise/physical activity and the increasing number of hours sitting down at work appear to be predictors of obesity. Single individuals were less prone to become obese than couples or widowed/divorced people. Finally, smoking status was statistically linked to the prevalence of obesity, since non-smokers or ex-smokers for more than 1 year presented a higher tendency for a BMI > 30.ConclusionsThis survey confirms that a priority area for health intervention aimed at preventing the development of obesity should be to increase levels of physical activity, although the approach will depend on the population, especially with respect to educational and socioeconomic aspects.

Prevalence Of Obesity

Background and Aims: This article aimed at assessing the 10-year trends (2000-2010) in the prevalence of overweight and obesity among the Balearic Islands' adult population. Methods: Body mass index (BMI, kg/m2) for young (18-35 year-olds) and middle-aged (36-55 year-olds) adults living in the Balearics was calculated. Data represented 1,089 people during 1999-2000 and 1,081 people during 2009-2010. The BMI categories were as follows: normal weight (18.5 < 25), overweight (25.0 < 30) and obese (≥30). Results: Weighted frequency estimates and logistic regression analysis were used to calculate overweight and obesity trends. While the prevalence of overweight and obesity mostly remained stable over the 2000-2010 period, the prevalence of obesity increased from 5.1 to 8.3% in young adults (aged 18-35), a 1.66-fold increase in prevalence (95% CI 1.02-2.70) over the study period. Conclusions: Total overweight and obesity prevalence remained stable in the Balearic adult population; however, a rising prevalence of obesity has been observed in young adults, which suggests a need to develop and change current strategies in order to reverse the current trends in obesity among this age group.

Reported Data

Background: Health Interview Survey (HIS) collects only self-reported height and weight to estimate obesity prevalence. Because of self-reporting, estimated obesity prevalence could be too low. From 2008 to 2012 an Health Examination Survey/Osservatorio Epidemiologico Cardiovascolare (HES/OEC) has been implemented in Italy with the aim of assessing cardiovascular (CV) risk factors, prevalence of risk conditions and CV diseases for the Italian adult population. Differences in measured and self-reported main anthropometric measures are described. Methods: Random samples of general population stratified by age and sex were examined in all Italian regions (participation rate 56%). Self-reported height and weight were requested to participants just after the welcome at the screening center. Height and weight were then measured using standardized procedures and methods. BMI was categorized in 3 groups: normal (BMI<25 kg/m2), overweight (25<=BMI<30 kg/m2), obesity (BMI>=30 kg/m2). Comparisons between measured and reported height, weight, and calculated BMI in men and women were assessed using t-test for means and chi-squared test for prevalence for paired samples. Results: Data from 2,583 men and 2,575 women aged 35-79 years were analysed. In men, measured height was lower than self-reported (-2.1 cm.), measured weight resulted higher than self-reported (+0.3 kg.); as a consequence BMI calculated on measured data resulted higher than that based on self-reported data (+0.8 kg/m2). Prevalence of obesity was higher for measured data than for self-reported (+7.1%). In men, difference between measured and self-reported height resulted higher in obese category than in the overweight or normal groups (-2.6 cm.), as well as for weight (+1.6 kg.). Similar results were registered in women: measured height was lower than self-reported (-3.6 cm.), measured weight resulted higher than self-reported (+0.8 kg.); as a consequence BMI calculated on measured data resulted higher than that based on self-reported data (+1.6 kg/m2). Prevalence of obesity was higher for measured data than for self-reported (+9.2%). Difference between measured and self-reported height resulted higher in obese category than in the overweight or normal groups (-5.0 cm.), as well as for weight (1.8 kg.). Both in men and women differences increased by age-group. Conclusions: Our results confirm how important is to produce standardised measures, also to adjust and correct self-reported height and weight, in order to have a reliable picture of obesity in the population. At present obesity is still a priority in public health and is one of the main indicator to plan community actions for cardiovascular disease prevention in the population.

And Gender

Childhood obesity is a major public health challenge and its prevalence continues to increase in many, but not all, countries worldwide. International data indicate that the prevalence of obesity is greater among boys than girls 5–19 years of age in the majority of high and upper middle-income countries worldwide. Despite this observed sex difference, relatively few studies have investigated sex-based and gender-based differences in childhood obesity. We propose several hypotheses that may shape the research agenda on childhood obesity. Differences in obesity prevalence may be driven by gender-related influences, such as societal ideals about body weight and parental feeding practices, as well as sex-related influences, such as body composition and hormones. There is an urgent need to understand the observed sex differences in the prevalence of childhood obesity; incorporation of sex-based and gender-based analysis in all childhood obesity studies may ultimately contribute to improved prevention and treatment.
