Resumo O surgimento da COVID-19 no Brasil explicitou ainda mais a enorme discrepância entre diferentes realidades sociais que coexistem no país, reacendendo as discussões acerca da segurança alimentar e nutricional, à semelhança do que vem acontecendo em outros países que enfrentam a mesma situação de pandemia. Argumenta-se neste trabalho que os riscos para a Segurança Alimentar e Nutricional (SAN) e a fome dos brasileiros já vinham se apresentando desde 2016, sendo agora aprofundados pela emergência da epidemia da COVID-19, passando a exigir compreensão da extensão e da magnitude dos problemas e articulação de medidas governamentais nas três esferas de gestão (federal, municipal e estadual), que possam assegurar o acesso à alimentação adequada e saudável, com vistas a reduzir os impactos negativos da doença na condição de alimentação, saúde e nutrição dos mais vulneráveis. Assim, este texto pretende contribuir para o debate sobre as medidas a serem adotadas pelos governos e sociedade para promover e garantir a SAN e impedir que a insegurança e a expansão da fome avancem durante e após a crise social e sanitária gerada pela pandemia.

This study aimed to assess pre-hypertension and hypertension-related factors in 1,125 sevento-14-year-old ). Hypertension was associated with overweight (OR: 3.02; female gender (OR: 2.49;. In short, prevalence of pre-hypertension and hypertension in children and adolescents was higher among girls and individuals with overweight and inadequate diet.

This study aimed to assess factors associated with anemia in schoolchildren. All subjects (N = 1,013; age 7-14 yrs.) p = 0.020 and OR < 50% adequacy = 1.68; p = 0.016) and family income below 1 minimum wage (OR = 1, 42; p = 0.035). Anemia prevalence in children and adolescents was high, especially among the poorest subjects and those with low intake of bioavailable iron.

Brazil is among the countries with the highest prevalence of asthma in the world, and the prevalence is still growing.

Amongst overweight/obese adolescents, those with slight and moderate body image dissatisfaction were less likely to follow a Western-like dietary pattern when compared with those satisfied with their body image. Additionally, in this group, adolescents with high body image dissatisfaction was more likely to follow a restrictive pattern.

MCMD must be taken into account in programmes for the treatment and prevention of malnutrition, especially in areas of low malnutrition prevalence.

Abstract. To determine the role of moderate-and low-intensity infections with Schistosoma mansoni and intestinal helminths (hookworm, Trichuris trichiura, Ascaris lumbricoides) on the prevalence of anemia and their relationship to iron consumption, a cross-section of 1,709 children in rural Brazil was studied. All participants were selected for infection with one or multiple helminthic parasites, and demographic, anthropometric, and dietary intake were surveyed. The prevalence and intensity were as follows: hookworm infection, 15.7% and 8.6 eggs/g; T. trichiura, 74.8% and 190.5 eggs/g; A. lumbricoides, 63% and 1,905.5 eggs/g; S. mansoni, 44.5% and 60.3 eggs/g. There was no increase in odds ratio for anemia with any combination of intestinal helminths without S. mansoni infection. By logistic regression, the odds ratio for having anemia when infected with S. mansoni and two intestinal helminths was 1.7 (95% CI, 1.1-2.5) and for S. mansoni and three intestinal helminths was 2.4 (95% CI, 1.2-4.6) compared with children with a single parasite species. Children with an adequate intake of iron had no increased odds of anemia independent of the combination of parasite infections.

IMPORTANCE Despite progress toward reducing global incidence, leprosy control remains a challenge in low-and middle-income countries. OBJECTIVE To estimate new case detection rates of leprosy among household contacts of patients with previously diagnosed leprosy and to investigate its associated risk factors. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study included families registered in the 100 Million Brazilian Cohort linked with nationwide registries of leprosy; data were collected from January 1, 2007, through December 31, 2014. Household contacts of patients with a previous diagnosis of leprosy from each household unit were followed up from the time of detection of the primary case to the time of detection of a subsequent case or until December 31, 2014. Data analysis was performed from May to December 2018. EXPOSURES Clinical characteristics of the primary case and sociodemographic factors of the household contact. MAIN OUTCOMES AND MEASURES Incidence of leprosy, estimated as the new case detection rate of leprosy per 100 000 household contacts at risk (person-years at risk). The association between occurrence of a subsequent leprosy case and the exposure risk factors was assessed using multilevel mixed-effects logistic regressions allowing for state-and household-specific random effects. RESULTS Among 42 725 household contacts (22 449 [52.5%] female; mean [SD] age, 22.4 [18.5] years) of 17 876 patients detected with leprosy, the new case detection rate of leprosy was 636.3 (95% CI, 594.4-681.1) per 100 000 person-years at risk overall and 521.9 (95% CI, 466.3-584.1) per 100 000 person-years at risk among children younger than 15 years. Household contacts of patients with multibacillary leprosy had higher odds of developing leprosy (adjusted odds ratio [OR] , 1.48; 95% CI, 1.17-1.88), and the odds increased among contacts aged 50 years or older (adjusted OR, 3.11; 95% CI, 2.03-4.76). Leprosy detection was negatively associated with illiterate or preschool educational level (adjusted OR, 0.59; 95% CI, 0.38-0.92). For children, the odds were increased among boys (adjusted OR, 1.70; 95% CI, 1.20-2.42). CONCLUSIONS AND RELEVANCE The findings in this Brazilian population-based cohort study suggest that the household contacts of patients with leprosy may have increased risk of leprosy, especially in households with existing multibacillary cases and older contacts. Public health interventions, such as contact screening, that specifically target this population appear to be needed.
