The Latin American Consortium of Studies in Obesity (LASO)
ABSTRACT Current, high-quality data are needed to evaluate the health impact of the epidemic of obesity in Latin America. The Latin American Consortium of Studies of Obesity (LASO) has been established, with the objectives of (i) Accurately estimating the prevalence of obesity and its distribution by sociodemographic characteristics; (ii) Identifying ethnic, socioeconomic and behavioural determinants of obesity; (iii) Estimating the association between various anthropometric indicators or obesity and major cardiovascular risk factors and (iv) Quantifying the validity of standard definitions of the various indexes of obesity in Latin American population. To achieve these objectives, LASO makes use of individual data from existing studies. To date, the LASO consortium includes data from 11 studies from eight countries (Argentina, Chile, Colombia, Costa Rica, Dominican Republic, Peru, Puerto Rico and Venezuela), including a total of 32 462 subjects. This article describes the overall organization of LASO, the individual studies involved and the overall strategy for data analysis. LASO will foster the development of collaborative obesity research among Latin American investigators. More important, results from LASO will be instrumental to inform health policies aiming to curtail the epidemic of obesity in the region.

- "These discrepancies in types of foods purchased and consumed in major urban areas and the Northern states of Mexico may partially account for the interactive effects noted between higher levels of education and increased obesity risks for rural residents and men. The increase in sedentary lifestyles across Mexico in conjunction with changing dietary patterns   raises serious public health concerns that require programs and policies targeted at the appropriate subgroups experiencing increasing and continued high rates of obesity. Third, an interesting association was noted in the multilevel logistic regression models in that an independent negative association was noted between the level of marginality in a respondent's municipio and their risk of being obese. "
ABSTRACT: This paper assesses individual and social environment determinants of obesity in the adult Mexican population based on socioeconomic position, rural residence, and areal deprivation. Using a nationally representative health and nutrition survey, this analysis considers individual and structural determinants of obesity from a socioeconomic position and health disparities conceptual framework using multilevel logistic regression models. We find that more than thirty percent of Mexican adults were obese in 2006 and that the odds of being obese were strongly associated with an individual's socioeconomic position, gender, place of residence, and the level of marginalization (areal deprivation) in the place of residence. Surprisingly, areas of the country where areal deprivation was highest had lower risks of individual obesity outcomes. We suggest that programs oriented towards addressing the health benefits of traditional food systems over high-energy dense refined foods and sugary beverages be promoted as part of a public health program aimed at curbing the rising obesity prevalence in Mexico.01/2012; 2012(2090-4029).

ABSTRACT: Obesity is a major worldwide problem in public health, reaching epidemic proportions in many countries, especially in urbanized regions. Bariatric procedures have been shown to be more effective in the management of morbid obesity, compared to medical treatments in terms of weight loss and its sustainability. The two most commonly performed procedures are laparoscopic Roux-en-Y gastric bypass (LRYGB), laparoscopic adjustable gastric banding (LAGB), and the novel laparoscopic sleeve gastrectomy (LSG). The MEDLINE database (cutoff date September 2010), LILACS, and the Cochrane Library were searched using the key words "gastric bypass," "sleeve gastrectomy," and "gastric banding." Only studies that compared at least two of the laparoscopic procedures were included. Reviews and meta-analysis, editorial letters or comments, case reports, animal or in vitro studies, comparisons with medical treatment, comparisons with open (non-laparoscopic) procedures were excluded. Most studies indicated that LRYGB and LSG could be more effective achieving weight loss than LAGB. However, LAGB seems to be a safer procedure with frequent, but less severe, long-term complications. Although not uniformly reported, a resolution of obesity-related comorbidities was achieved with most bariatric procedures. The three procedures have acceptable efficacy and safety. We believe that patients should be informed in detail on the advantages and disadvantages of each available procedure, possibly in several interviews and always accompanied by a specialized interdisciplinary team, warranting long-term follow-up.Obesity Surgery 04/2011; 21(9):1458-68.

ABSTRACT: Biomass-derived indoor air pollution has been associated with increased risks of respiratory diseases; however, relatively few studies have examined the cardiovascular effects of biomass burning. We measured 48-hour indoor fine particulate matter and indoor and personal carbon monoxide (CO) concentrations in 124 households using open-fire cook stoves in Nicaragua. We also examined the cross-sectional relationship of air pollution and health. High air pollutant concentrations with considerable variability were measured. Nonsignificant elevations in systolic blood pressure were associated with increases in CO concentrations. These associations were stronger among obese participants; an 8.51 mmHg (95% confidence interval [CI]: 3.06, 13.96) increase in systolic blood pressure per 24 ppm increase in 48-hour average indoor CO levels was observed. Although the cross-sectional design of this study limits the interpretation, we observed evidence of a relationship between indoor air pollution and blood pressure and heart rate, two indicators of cardiovascular health.International journal of occupational and environmental health 04/2011; 17(2):113-21.
