Perfil de crescimento de crianças matriculadas em programa de suplementação alimentar

The growth profile of 1,511 children attending a supplementary feeding program was studied over the year after admission. The children, aged 6 to 72 month and from five cities of the Greater S. Paulo region (Brazil), were attending the official Brazilian supplementary "Nutrition and Health Program" (PNS). Weight and height for age were used as indicators, and were expressed as centile values of the anthropometric reference standard (NCHS). At admission, the profile for weight and for height was deviated to the left, showing a great concentration of children in the lower deciles and few in the higher ones, thus characterizing a malnourished population. One year later, the growing profile of the children showed an improvement of the nutritional status, as there had been a noteworthy decrease in the number of children in the first decile for all ages in both weight and height. The height of the children age 12 to 24 month showed a great improvement as 49% of them had been in the first decile at admission, but this percentage diminished to 18% after just one year on the program.Com o objetivo de conhecer o perfil de crescimento de beneficiários de um programa de suplementação alimentar, estudou-se 1511 crianças de 6 a 72 meses de idade, de cinco municípios da Grande São Paulo, Brasil que freqüentaram o Programa de Nutrição em Saúde (PNS), pelo período de um ano. Foram utilizados indicadores peso e altura para a idade, expressos em valores de percentís correspondentes ao padrão antropométrico de referência NCHS. Esse perfil foi traçado no momento da matrícula e após um ano de programa, segundo grupos etários, momento em que o perfil encontrado estava desviado para a esquerda, tanto para as distribuições de peso como de altura, concentrando maior freqüência de crianças nos primeiros decis e escassez no últimos, caracterizando uma população desnutrida. O perfil correspondente aos dois indicadores, após um ano de programa, evidenciou melhora do estado nutricional, uma vez que houve acentuada diminuição da freqüência das crianças no primeiro decil (P10) em todas as faixas etárias, tanto para peso como para altura, destacando-se a faixa de 12 a 24 meses, cuja freqüência no primeiro decil de altura passou de 49%, na matrícula, para 18%, após 12 meses de suplementação alimentar

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
