“…Increased food intake and reduced physical activity are characteristic of both conditions (94). Bidirectional causation is also plausible, with suggestions that obesity may be a determinant of later depression in children (97)(98)(99) and conversely hypothesized mechanisms for depression causing obesity (93,95,(98)(99)(100). Indeed, it has more recently been suggested that these two comorbid conditions may mutually reinforce a progressive downward spiral in each other (101) and that additional insight into their longitudinal interaction may be important for intervention strategies (102).…”

The prevalence of childhood obesity has increased globally over the past three decades, with evidence of recent leveling off in developed countries. Reduction in the, currently high, prevalence of obesity will require a full understanding of the biological and social pathways to obesity in order to develop appropriately targeted prevention strategies in early life. Determinants of childhood obesity include individual level factors, including biological, social, and behavioral risks, acting within the influence of the child's family environment, which is, in turn, imbedded in the context of the community environment. These influences act across childhood, with suggestions of early critical periods of biological and behavioral plasticity. There is evidence of sex and gender differences in the responses of boys and girls to their environments. The evidence that determinants of childhood obesity act at many levels and at different stages of childhood is of policy relevance to those planning early health promotion and primary prevention programs as it suggests the need to address the individual, the family, the physical environment, the social environment, and social policy. The purpose of this narrative review is to summarize current, and emerging, literature in a multilevel, life course framework. INTRODUCTIONThe prevalence of childhood obesity has increased globally over the past three decades, with more rapid increases recently occurring in low-income countries (1). In the United States, more than 30% of children are now overweight or obese (1), with evidence that the prevalence has leveled off (2). Children and adolescents are exhibiting obesity-related conditions such as type 2 diabetes, elevated blood pressure, low-density lipoprotein cholesterol, and higher fasting insulin levels (3-6). In addition, childhood obesity predicts adulthood obesity and its known health consequences (7,8). Treatment of obesity is notoriously difficult, with weight loss rarely sustained in adults (9). Therapeutic interventions in childhood are somewhat more successful, particularly if the intervention occurs prior to onset of puberty (10). However, real and sustained progress in combating the obesity epidemic will require a full understanding of the biological and social pathways to obesity in order to develop appropriately targeted prevention strategies in early life.Pathways to childhood obesity are complex. It is therefore helpful to discuss determinants of obesity within a conceptual framework. A multilevel conceptual model, Bronfenbrenner's Bioecological Systems Theory (11), has previously been applied to the conceptualization of childhood obesity by Davison and Birch (12). This framework depicts individual-level factors, including biological, social, and behavioral risks, as acting within the influence of the child's family environment, which is, in turn imbedded in the context of the community environment. It is also helpful to consider critical periods for obesity risk and, as will be further illustrated in a later section,...

“…A insatisfação com o peso corporal constitui-se em um importante preditor de diversos agravos à saúde de adolescentes, como desordens alimentares; jejum prolongado; uso de laxantes e comportamento bulímico (2,9,10) ; alterações psicológicas, como depressão e baixa autoestima (11) ; e perda ou ganho de peso por métodos não-saudáveis, como o uso de esteroides para aumento de peso (12,13) e consumo de cigarro para controle de peso (3,14) .…”

RESUMOObjetivo: Estimar a ocorrência de insatisfação com peso corporal e os fatores associados em adolescentes.Métodos: Estudo transversal, representativo dos escolares de 15 a 19 anos de escolas públicas de Santa Catarina, no ano de 2002. O desfecho do estudo foi a satisfação com o peso corporal, avaliada pela pergunta: "Você está satisfeito(a) com seu peso corporal?". As variáveis avaliadas foram: sexo, idade, renda familiar, local de residência, estado nutricional, tempo semanal assistindo televisão, tabagismo e autopercepção de saúde. Investigaram-se também os seguintes comportamentos alimentares: tomar remédios para emagrecer, provocar vômitos após as refeições e realizar, no mínimo, três refeições/ dia. Empregou-se regressão multinomial nas análises bruta e ajustada.Resultados: Dentre os adolescentes avaliados (n=5.028), 16,7% (IC95%: 15,7-17,7) estavam insatisfeitos com seu peso e gostariam de aumentá-lo, e 36,2% (IC95%: 34,9-37,5) gostariam de diminui-lo. Tomar remédios para emagrecer, provocar vômitos após as refeições e não realizar, no mínimo, três refeições/dia foram mais frequentes entre aqueles que gostariam de reduzir o peso. Após análise ajustada, os fatores associados ao desejo de aumentar o peso foram: sexo masculino, idade ≥17 anos, residir na zona urbana, não ter excesso de peso e autopercepção de saúde negativa. Já os fatores associados ao desejo de diminuir o peso foram: sexo feminino, residir na zona urbana, ter excesso de peso e uma percepção negativa de saúde. Conclusões:Encontrou-se alta prevalência de insatisfação com o peso, sendo as variáveis sexo, estado nutricional e autopercepção de saúde os fatores mais fortemente associados a tal comportamento.Palavras-chave: peso corporal; percepção de peso; imagem corporal; adolescente. ABSTRACT Objective:To assess the prevalence of body weight dissatisfaction among adolescents and the associated factors.Methods: Population-based cross-sectional study covering a sample of students with ages from 15 to 19 years, attending public high schools in Santa Catarina, Brazil, in the year 2002. The outcome of the study was body weight satisfaction, assessed by the question: "Are you satisfied with your body weight?" The variables analyzed were gender, age, family income, home neighborhood, nutritional status, time of television viewing per week, smoking and self-rated health. Some feeding behaviors were also investigated: taking weight loss medication, vomiting after meals, and having at least three meals per day. A multinomial regression model was used in the crude and adjusted analyses.Results: Among the adolescents evaluated (n=5,028), 16.7% (95%CI: 15.7-17.7) were unsatisfied and would like to gain weight, and 36.2% (95%CI: 34.9-37.5) would like to reduce it. Frequent behaviors among those who wanted to reduce their body weight included: taking weight loss medication, Endereço para correspondência: Giovâni Firpo Del Duca Campus Universitário -Trindade -UFSC CEP 88040-900 -Florianópolis/SC

“…These include a variety of psychological problems, including disordered eating (Marmorstein, von Ranson, Iacono, & Malone, 2008;Stice & Bearman, 2001), conduct problems (Nock, Kazdin, Hiripi, & Kessler, Secular trends in depressive symptoms 6 2006), and substance abuse (Marmorstein, Iacono, & Malone, 2010). Moreover, studies have indicated that variables related to appearance, such as appearance dissatisfaction and body mass index (BMI), may be risk factors for depressive symptoms (Bearman & Stice, 2008;Needham & Crosnoe, 2005;Paxton, Neumark-Sztainer, Hannan, & Eisenberg, 2006). Likewise, there is some support for that lack of exercise is increasing the likelihood for experiencing depressive symptoms (Biddle & Asare, 2011).…”
