Abstract Background Low vaccination rates and under-detection of cases in adolescents and young adults have been implicated in the transmission of Pertussis to children. In this study, the proportion of adolescents and young adults with anti Bordetella pertussis IgG antibodies was estimated in a population-based survey in Mexico. Methods Frozen sera and data from 1,581 subjects—1,102 adolescents and 479 young adults (10–19 and 20–25 years old, respectively)—56% female were randomly selected from the Mexico’s National Health and Nutrition Survey (ENSANUT) 2012. CDC/FDA validated PT ELISA test was used to detect anti-pertussis toxin (PT) antibodies. A subset of 300 samples was also tested with Bp-IgG PT ELISA kit (Euroimmun AG, Lubeck, Germany®), both tests used international standards. Threshold values were established to identify vaccination or infection within the previous year, according to a US survey (Baughman et al.). Population-weighted estimates of seroprevalence were calculated. Results Overall Bp seroprevalence was 3.9% (95% CI: 2.3, 6.3); 3.1% (1.9, 5.0) in adolescents, and 4.9% (2.2, 11) in young adults. Seroprevalence did not significantly vary by gender, socioeconomic status, region or rural/urban location. Compared with the CDC/FDA PT ELISA, the Euroimmun® test showed 76% sensitivity, 88% specificity. Conclusion Booster vaccination to Bp after toddlerhood is not in the Mexican national policy; therefore, anti-PT IgG seropositivity may reasonably be attributed to recent Bp infection. Our weighted estimates of recent Bp infection, which are based on a national population-based serosurvey and a standardized serological test, represent a considerable burden of infections in adolescents and young adults that sharply contrast with the official surveillance reports. Also, the Bp-IgG PT ELISA commercial kit lower sensitivity than the CDC/FDA PT ELISA may lead underestimation of recent infections. In conclusion, assessing pertussis seroprevalence requires careful consideration of the right tests and epidemiological model for interpretation. Disclosures All authors: No reported disclosures.

Abstract The present study aimed to elucidate the relationship between cola consumption and bone mineral density (BMD) in Korean adolescents and young adults. We used data from the Korea National Health and Nutrition Examination Survey 2008–2011. A total of 2499 adolescents and young adults aged 12–25 years were included. The study participants were classified as cola drinkers and non-cola drinkers according to 24-h dietary recall data. BMD was measured using dual X-ray absorptiometry. In the male population, whole body, whole femur and femoral neck BMD in cola drinkers were lower than that of non-cola drinkers by 4% (95% CI −0⋅071, −0⋅007), 5% (−0⋅092, −0⋅012) and 5% (−0⋅090, −0⋅001), respectively. In both sex groups, cola drinkers had less frequent milk consumption than non-cola drinkers. However, there were no significant differences in cola consumption according to calcium intake in both sexes. In conclusion, cola intake and BMD were inversely associated with Korean male adolescents and young adults. Considering the importance of peak bone mass attainment at adolescents and the increasing trend in carbonated beverage consumption in South Korea, further studies are needed to elucidate the causality between cola intake and lower BMD.

Objective. To examine actual and perceived weight in national cohorts of Mexican-origin adult men in Mexico and the United States (US). Materials and methods. We used the 2001-06 National Health and Nutrition Examination Survey and the 2006 Mexican National Health and Nutrition Survey. Results. The prevalence of overweight or obesity (OO) in Mexicans was 65% and in Mexican-Americans was 72%. OO Mexican-American men were more likely than OO Mexican men (56 vs. 49%) to perceive themselves as “overweight”. Among OO men from both populations, those who had been screened for OO by a health provider were almost seven times more likely to have accurate weight perceptions. Only 9% of OO men in Mexico and 25% in the US recalled having been screened for weight. Conclusion. Weight misperceptions were common in both populations but more prevalent in Mexico; low screening by providers may contribute to poor weight control in both countries

The Cost

El objetivo de este estudio fue medir y comparar el comportamiento inflacionario del costo de las Bebidas Habituales y del costo de la Jarra de Bebidas Recomendada para la población mexicana. Basados en información sobre el consumo de bebidas en adultos (Encuesta Nacional de Salud y Nutrición) y de los precios promedio mensuales (Instituto Nacional de Estadística y Geografía) para cada bebida durante enero 2012 - Junio 2017, se calcularon los costos del consumo y la inflación de bebidas habitual y recomendado. El costo de las Bebidas Recomendadas es consistentemente mayor que el de las Bebidas Habituales. Las tasas de inflación son similares excepto en 2014 cuando se introdujo el impuesto a las bebidas azucaradas. Se encuentra que los precios y la inflación de las bebidas con azucares añadidos y de las bebidas habituales responden menos que proporcionalmente. Una inflación del costo de las bebidas recomendadas más alta que las habituales puede incrementar la demanda por bebidas habituales. El comportamiento de la inflación revela que el impuesto a bebidas azucaradas puede ser efectivo pero transitorio. The aim of this study was to measure and compare the inflationary behavior of the Usual Drinks Intake cost and the Recommended Drinks Intake Jar cost for the Mexican population. Based on information about the consumption of drinks in adults (National Health and Nutrition Survey) and of the average monthly prices (National Institute for Statistic and Geography) for each specific drink during January 2012-June 2017, we calculate consumption costs and inflation of usual and recommended drink intakes. The cost of the recommended drinks is consistently higher than the usual drinks cost. Inflation rates are similar in both drink intakes except in 2014, when the tax to sugary drinks was implemented. Prices and inflation of sugary drinks and usual drinks respond less than proportionally. A higher inflation of recommended drink costs compared to the usual drinks inflation could increase the demand for usual drinks. The behavior of inflation reveals that the tax to sugary drinks can be effective, but transitory.
