Factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil: a hierarchical approach.

The objective of this article is to identify the prevalence and evaluate the factors associated with extreme weight loss behaviors among adolescents of Northeastern Brazil. Cross-sectional study with 2,439 adolescents from Sample 2 (2015) of the National School-based Health Survey. Extreme weight loss behaviors, such as self-induced vomiting, laxative use and use of medicines or formulas (outcome) and independent variables were evaluated using a self-administered electronic questionnaire. The statistical analysis was performed following a hierarchical conceptual model. The prevalence of extreme weight loss behaviors in the sample was 12.1%. Among the factors that showed significant association with the outcome, we emphasize the administration model of the private school (PR = 0.62; CI = 0.46-0.84), bullying related to body appearance and for other reasons (PR = 1.62; CI = 1.19-2.20), forced sexual intercourse (PR = 2.65; CI = 1.90-3.69), insomnia (PR = 1.84; CI = 1.43-2.37), and be perceived as fat or very fat (PR = 1.90; CI = 1.50-2.42). Moderate prevalence of extreme weight loss behaviors was identified among adolescents. Socioeconomic factors, exposure to violence, mental health, and body image were associated with the adoption of these behaviors.

Resumo O objetivo deste artigo é identificar a prevalência e avaliar os fatores associados aos comportamentos extremos para perda de peso em adolescentes do Nordeste brasileiro. Estudo transversal com 2.439 adolescentes da Amostra 2 (2015) da Pesquisa Nacional de Saúde do Escolar. Os comportamentos extremos para perda de peso (desfecho) e as variáveis independentes foram avaliadas por meio de um questionário eletrônico autoaplicável. A análise estatística foi realizada seguindo um modelo conceitual hierárquico. A prevalência de comportamentos extremos para perda de peso na amostra foi de 12,1%. Entre os fatores que mostraram associação significativa com o desfecho, destacam-se a situação administrativa da escola privada (RP = 0,62; IC = 0,46-0,84), ser vítima bullying relacionado à aparência corporal e pelos demais motivos (RP = 1,62; IC = 1,19-2,20), ser forçado a ter relação sexual (RP = 2,65; IC = 1,90-3,69), ter insônia (RP = 1,84; IC = 1,43-2,37) e se autoperceber como gordo ou muito gordo (RP = 1,90; IC = 1,50-2,42). Prevalência moderada de comportamentos extremos para perda de peso foi identificada entre os adolescentes. Os fatores socioeconômicos, de exposição à violência, de saúde mental e da imagem corporal se associaram à adoção de tais comportamentos.

Impact of cash transfer programs on birth and child growth outcomes: systematic review.

To investigate the impact of cash transfer (CTs) on birth outcomes, including birth weight, low birth weight and prematurity, as well as child physical growth were included, as assessed by anthropometric indices in children under five years of age. Searching was performed using the PubMed/Medline, Embase, LILACS, Cochrane Library, Scopus and Web of Science databases. Quantitative observational, experimental and quasi-experimental. Eleven studies were included in the review. The majority (81.8%) were carried out in low-and middle-income countries and most involved conditional CTs (63.6%). Four were clinical trials and seven were observational studies. Conditional CTs were found to be associated with a reduction in height-for-age (-0.14; 95%CI -0.27, -0.02); (OR 0.85; 95%CI 0.77-0.94); (OR = 0.44; 95%CI 0.19-0.98), a significantly reduced chance of low weight-for-age (OR = 0.16; 95%CI -0.11-0.43), low weight-for-height (OR = -0.68; 95%CI -1.14, -0.21), and low weight-for-age (OR = 0.27; 95%CI 0.10; 0.71). Unconditional CTs were associated with reduced birth weight (RR = 0.71; 95%CI 0.63-0.81; p < 0.0001) and preterm births (RR = 0.76; 95%CI 0.69-0.84; p < 0.0001). Conditional CTs can positively influence birth outcomes and child growth.
