Os efeitos deletérios do excesso de peso sobre a saúde dos cães são bastante citados na literatura, mas pouco investigados. O termo hiperlipidemia refere-se ao aumento da concentração de lipídeos (colesterol, triglicérides ou ambos) séricos. As desordens lipídicas são relativamente comuns nos cães e estas condições podem ocorrer como resultado de um defeito primário no metabolismo de lipoproteínas ou como conseqüência de doença sistêmica subjacente. O objetivo deste estudo foi avaliar a frequência de animais obesos que apresentam alterações nas concentrações de lipídios séricos e analisar a possível correspondência desta condição com grau de obesidade, sexo, idade e castração. Foram incluídos 30 cães obesos com escore de condição corporal (ECC) igual ou superior a 8 (em escala de um a nove, com nove representando obesidade acentuada) e um grupo controle de dez animais com ECC igual a cinco. Nos animais com ECC 9 (n=21), foi encontrada freqüência de 52,4% (n=11) de cães com hipercolesterolemia e 33,3% (n=7) com hipertrigliceridemia. Nos animais com EEC 8 (n=9) foi encontrada freqüência de 22,2% (n=2) de hipercolesterolemia e de 33,3% (n=3) de hipertrigliceridemia. Estas alterações também apresentaram correspondência com o sexo feminino, faixa etária entre quatro e sete anos e a castração. Todavia, a elevação destes metabólitos foi moderada e não se situou em faixa de reconhecido risco à saúde / The harmful effects of obesity on dog health are quite mentioned in the literature, but little investigated. The term hyperlipidemia refers to the increase of lipid and/or fat concentration (cholesterol, triglycerides or both) in serum. These disorders are relatively common in dogs and may happen as a result of a primary defect in metabolism of lipoproteins or as a consequence of a subjacent systemic disease. The aim of this study was to evaluate the frequency of obese dogs that present alterations on cholesterol and triglycerides serum concentration, and to study the correlation of these disorders with obesity degree, sex, age and castration. Thirty obese dogs with body condition score (BCS) equal or superior to 8 (on a scale between one to nine, and nine representing severe obesity) and a control group of ten dogs with BCS of 5 were included. Animals with BCS of 9 (n=21 dogs) presented a frequency of 52.4% (n=11 dogs) of hypercholesterolemia and 33.3% (n=7) of hypertriglyceridemia. Dogs with BCS of 8 (n=9) presented a frequency of 22,2% (n=2) of hypercholesterolemia and 33,3% (n=3) of hypertriglyceridemia. These alterations also presented correspondence with female sex, age between 4 and 7 years and castration. However, the cholesterol and triglycerides increases were moderate, and not remained within the range of recognized health risk

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders among women of childbearing age and is associated with a number of metabolic disturbances. It has been hypothesised these women carry an increased risk of developing cardiovascular diseases (CVD) with advancing age. The first aim of this thesis was to establish the prevalence of PCOS-related symptoms in Northern Sweden. The Northern part of the WHO MONICA project was used for this purpose. Based on self-reported menstrual disturbances and hirsutism together with biochemical analyses of free androgen index, the estimated prevalence of PCOS in Northern Sweden was 4.8%, which corresponded with previous prevalence studies. Disturbances in the fibrinolytic system are predictors of future cardiovascular events and measurements of plasminogen activator inhibitor 1 (PAI-1) activity and tissue plasminogen activator (tPA) mass concentration may be used to assess fibrinolytic activity in women with PCOS. From the findings, over-weight women with PCOS had impaired fibrinolysis, especially if they displayed objective biochemical markers of hyperandrogenism. Conversely, lean women with PCOS, displayed no signs of disturbed fibrinolysis. The adipose tissue is an active endocrine organ that produces and releases hormones, pro- and anti-inflammatory cytokines, and chemoattractant cytokines. Proinflammatory molecules produced by adipose tissue can be active participants in the development of insulin resistance and the increased risk of cardiovascular disease associated with obesity. The findings suggested being overweight, rather than the PCOS diagnosis per se, was the main explanatory variable for elevated adipose tissue inflammation in PCOS patients. Weight reduction is the primary target for intervention in overweight and obese women with PCOS. When this thesis was planned, no placebo-controlled trials on anti-obesity drugs in women with PCOS had been conducted. Sibutramine in combination with lifestyle intervention resulted in significant weight reduction in overweight women with PCOS. In addition to the weight loss, sibutramine appeared to have a beneficial effect on metabolic and cardiovascular risk factors.

The steady raise in childhood obesity is a major public health problem nationally and globally. Childhood obesity is primarily caused by an imbalance between caloric intake and caloric expenditure. The increase in childhood obesity rates over the past 3 decades suggested involvement of environmental and behavioral factors in the obesity epidemic. While childhood obesity is considered a public health crisis in the United States, only limited research is available about the potential impact of neighborhood-level factors such as access to healthy food, neighborhood safety, and risk-free outdoor playgrounds. The purpose of this study was to examine if any relationships existed between childhood obesity and type of diet, level of physical activity, and neighborhood-level risk factors and childhood obesity. This study accessed the California Health Interview Survey (CHIS) 2009-2014 data sets. Chi-square tests and multivariate logistic regression were used to evaluate the associations between independent and dependent variables. The Wald test was used to assess the effects of each individual predictor, while adjusting for other predictors. The findings of this study showed no significant associations between childhood obesity and neighborhood safety; parental educational level; presence of parks, playgrounds, or open spaces; neighborhood walkability; neighborhood safety and support; and gender. Low physical activity levels, however were a significant risk factor for increase obesity. This study may lead to positive social change, enhancing individual lives and whole communities, by drawing the awareness of public health officials and policy makers to the importance of neighborhood factors associated with high body mass index.

Childhood obesity is a foremost concern throughout the health care community. Approximately 17.6% of the pediatric population meet the criteria for obesity, which can lead to health disparities later in life, such as hypertension, type 2 diabetes mellitus, and metabolic syndrome. Emerging mobile and wearable lifestyle tracking devices can be a viable solution to the challenging problem of childhood obesity through behavior changes, feasibility, and adherence. The purpose of this literature review was to determine the effect that mobile and wearable activity tracking devices have on the obese pediatric population. A centralized review of the literature was conducted using various data basesand resulted in 19 articles. 5 articles were chosen to review in more detail. 13 other articles were hand searched through credible resource citations, rendering 14 articles that met all criteria. The three general themes found in this literature review suggest that wearable activity tracking devices can be designed and effectively used by the pediatric population. Also, wearable activity tracking devices are accurate in conveying information on physical activity, calories, and heart rate. Lastly, wearable activity tracking devices can initiate behavioral changes in children leading to an increase in physical activity, resulting in the prevention and treatment of pediatric obesity.While in a majority of the studies analyzed trails were short. The research suggests wearable activity tracking devices will produce the desired results of increased activity in pediatric populations when they are worn correctly, are adequately engaging, and when they are designed in a feasible manner that is appealing to children.
