“…One study 16 showed that low levels of HDL-C were associated in a signifi cant manner to the presence of obesity. Another study involving teenagers also observed no relationship between abdominal obesity and changes in total cholesterol levels 17 .…”

Introduction: The growing prevalence of obesity is currently considered the most important nutritional disorder. It is characterized, according to the World Health Organization (WHO) as a worldwide epidemic in developing and developed countries. In an associated form, there is an increasing prevalence of dyslipidaemia. Aiming to improve the current situation and prevent the progression of the epidemic, the American Academy of Pediatrics recently reinforced the need for cholesterol screening in overweight children older than two years. Objective: To determine overweight and lipid profi le in children aged between six and nine years. Methods: A descriptive, cross-sectional study with children from Vitoria, ES. For nutritional classifi cation the Z-score > + 1 SD body mass index-forage (according to WHO / 2007) was used; for the lipid profi le the Atherosclerosis Prevention Guidelines in Childhood were used. Anthropometric measurements (weight, height, waist circumference and triceps skinfold thickness) followed the standard techniques described by WHO. Data were organized and analysed using SPSS, version 8.5 and calculated the absolute, relative and mean (SD) frequencies and the association between overweight, lipid profi le and other variables is adopted as signifi cant when p < 0.05. Results: The sample comprised a total of 511 children of both sexes (46.7% male), with a mean age of 101.6 ± 11.1 months. Overweight was found in 197 (38.5%) children: overweight in 71 (13.9%) and obesity in 126 (24.6%). Total cholesterol was elevated in 167 (32.7%) as were high LDL-C (136-27%). High triglycerides were found in 21 participants (4.1%). Signifi cant association was found between waist circumference and high levels of triglycerides (p = 0.019) and HDL-C (p = 0.033). Conclusion: Excess weight of the sample investigated is considered high and its health effects are important, with an increased total cholesterol greater than 32%. The high levels of HDL-C are protective factors for coronary heart disease, although the lipid profi le had been changed.

“…The use of BMI for diagnosing obesity in adolescents is well documented in the literature, as it has a good clinical applicability. Besides, BMI shows an association with visceral fat and a better correlation with blood pressure and lipid levels when compared to other anthropometric parameters ( 20 ) . However, this indicator should not be used alone, since underweight or normal weight individuals do not always present adequate body fat percentage.…”

OBJECTIVE: To study anthropometrical and body composition variables as predictors of risk for metabolic alterations and metabolic syndrome in female adolescents.METHODS: Biochemical, clinical and corporal composition data of 100 adolescents from 14 to 17 years old, who attended public schools in Viçosa, Southeastern Brazil, were collected.RESULTS: Regarding nutritional status, 83, 11 and 6% showed eutrophia, overweight/obesity and low weight, respectively, and 61% presented high body fat percent. Total cholesterol presented the highest percentage of inadequacy (57%), followed by high-density lipoprotein (HDL - 50%), low-density lipoprotein (LDL - 47%) and triacylglycerol (22%). Inadequacy was observed in 11, 9, 3 and 4% in relation to insulin resistance, fasting insulin, blood pressure and glycemia, respectively. The highest values of the fasting insulin and the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) were verified at the highest quartiles of body mass index (BMI), waist perimeter, waist-to-height ratio and body fat percent. Body mass index, waist perimeter, and waist-to-height ratio were the better predictors for high levels of HOMA-IR, blood glucose and fasting insulin. Waist-to-hip ratio was associated to arterial hypertension diagnosis. All body composition variables were effective in metabolic syndrome diagnosis.CONCLUSIONS: Waist perimeter, BMI and waist-to-height ratio showed to be good predictors for metabolic alterations in female adolescents and then should be used together for the nutritional assessment in this age range.

“…Elevation of CRP might lead to insulin resistance and CVD [6]. The worldwide prevalence of obesity is rising in developed and developing countries [2], both in adults and in adolescents [1, 7]. Recent research suggests that prevalence of obesity is increasing in Iran, especially in women [5, 8].…”

Studies regarding the effects of high protein (HP) diets on cardiovascular (CVD) risk factors have reported contradictory results. We aimed to determine the effects of an HP diet on CVD risk factors and high-sensitivity C-reactive protein (hs-CRP) among overweight and obese women. In this randomized controlled trial, we recruited 60 overweight and obese women, aged 20–65, into an HP or energy-restricted control diet for three months (protein, carbohydrate, and fat: 25%, 45%, and 30% versus 15%, 55%, and 30%, resp.). Total protein was divided between animal and plant sources in a 1 : 1 ratio, and animal sources were distributed equally between meats and dairy products. Fasting blood samples, hs-CRP, lipid profile, systolic and diastolic blood pressure, and anthropometric measurements were assessed using standard guidelines. Percent change was significantly different between the two diet groups for weight (standard protein (SP): −3.90 ± 0.26 versus HP: −6.10 ± 0.34%; P < 0.0001, resp.) and waist circumference (SP: −3.03 ± 0.21 versus HP: −5.06 ± 0.28%; P < 0.0001, resp.). Percent change of fasting blood glucose (FBG) substantially decreased in the control group compared to the HP group (−9.13 ± 0.67 versus −4.93 ± 1.4%; P = 0.01, resp.). Total cholesterol, systolic blood pressure (SBP), and diastolic blood pressure (DBP) decreased both in the HP and in the control diet groups (P = 0.06, P = 0.07, and P = 0.09, resp.); however, the results were marginally significant. Serum levels of hs-CRP were reduced both in the control (−0.08 ± 0.11%, P = 0.06) and in the high protein groups (−0.04 ± 0.09%, P = 0.06). The energy-restricted HP diet resulted in more beneficial effects on weight loss and reduction of waist circumference. CVD risk factors may improve with HP diets among overweight and obese women. When using isoenergetic weight loss diets, total cholesterol, hs-CRP, and SBP were marginally significantly reduced, independent of dietary protein content. This trial is registered with ClinicalTrials.gov NCT01763528.
