OBJECTIVE: To determine the best cut-offs of body mass index for identifying alterations of blood lipids and glucose in adolescents. METHODS: A probabilistic sample including 577 adolescent students aged 12-19 years in 2003 (210 males and 367 females) from state public schools in the city of Niterói, Southeastern Brazil, was studied. The Receiver Operating Characteristic curve was used to identify the best age-adjusted BMI cut-off for predicting high levels of serum total cholesterol (>150mg/dL), LDL-C (>100mg/dL), serum triglycerides (>100mg/dL), plasma glucose (>100mg/dL) and low levels of HDL-C (< 45mg/dL). Four references were used to calculate sensitivity and specificity of BMI cut-offs: one Brazilian, one international and two American. RESULTS: The most prevalent metabolic alterations (>50%) were: high total cholesterol and low HDL-C. BMI predicted high levels of triglycerides in males, high LDL-C in females, and high total cholesterol and the occurrence of three or more metabolic alterations in both males and females (areas under the curve range: 0.59 to 0.67), with low sensitivity (57%-66%) and low specificity (58%-66%). The best BMI cut-offs for this sample (20.3 kg/m² to 21.0 kg/m²) were lower than those proposed in the references studied. CONCLUSIONS: Although BMI values lower than the International cut-offs were better predictor of some metabolic abnormalities in Brazilian adolescents, overall BMI is not a good predictor of these abnormalities in this population.

OBJECTIVE: To describe the percentile distribution of body mass index (BMI) in school adolescents, by gender and age, comparing them with international parameters. SUBJECTS AND METHODS: The study included 8,020 adolescents aged 10-15 years from 43 schools in the city of São Paulo, southeastern Brazil. BMI values of the study sample were distributed in percentiles and compared to international parameters (CDC, Must and cols. and Cole and cols.). RESULTS: Both male and female adolescents aged 10 to 14 years showed BMI cut-offs over the international parameters, especially in the P50-P85 percentile range. At the age of 15, the observed values were very similar to reference data; however, BMI values in the 95th percentile were much higher than international parameters. CONCLUSIONS: The study results show how important it is to use adequate BMI values for Brazilian adolescents aged 10-15 since international parameters may not reflect the actual nutritional status of this group.

Objectives: The aim of this study was to determine the prevalence of abdominal obesity and its associated factors among adolescents, independent of confounders. Method: A sample of 14–17-year-old individuals (n=1.231), who were students from Londrina/PR-Brazil public schools, was studied. A questionnaire about physical activity, sedentary behaviour and socioeconomic conditions was applied. Anthropometry was composed of body weight (kg), height (m), body mass index (BMI=kg/m²) and waist circumference (cm). The association of abdominal obesity and independent variables was assessed using the chi-square test and the magnitude of associations was verified using Binary Logistic Regression in an unadjusted model and adjusted for confounders (gender, age, socioeconomic status, physical activity and sedentary behaviour). The confidence interval and statistical significance were set at 95% and 5%, respectively, using SPSS v15.0. Results: The abdominal obesity prevalence was 17.5% (CI = 15.4%–19.6%), and was higher in boys than in girls. Adolescents with abdominal obesity had higher values of body weight, height, body mass index and sedentary behaviour compared to eutrophic individuals. Being male increased the risk of abdominal obesity by 36% in adolescents. This risk was two times higher in those with high levels of sedentary behaviour. Conclusion: Abdominal obesity was significantly associated with gender and high levels of sedentary behaviour, regardless of confounding factors. Lifestyle habits are important modifiable risk factors that can effectively contribute to the reduction of obesity from an early age.

Objective: The objective of this study was twofold. First, analyze physical activity (PA) levels during physical education (PE) with different durations (45 and 90 minutes) according to student’s obesity status. Secondly, we examine the relative contribution of 45 and 90 minutes PE (45PE and 90PE) for the compliance of the daily PA recommendations according to the body mass index (BMI). Methods: Four public schools were analyzed. The sample comprised 472 youngsters (266 girls) aged between 10 and 18 years old. PA was assessed using an Actigraph accelerometer. The participants were categorized as non-overweight (NOW) and overweight/obese (OW) according to the sex-adjusted BMI. Results: The proportion of Moderate and Vigorous Physical Activity (MVPA) was lower than the 50% recommended by guidelines regardless the PE duration. Our data showed that only 26% of NOW and 13% of OW in the 45PE achieved the recommended levels while 17% of NOW and 11% of OW achieved the recommendation in 90PE. Overall, the 90PE had a higher absolute contribution for daily MVPA recommendations compliance than 45PE. Conclusion: During PE classes youngsters spent a reduced amount of time in MVPA, independently of their weight status.Resumen. Objetivo: Este estudio tiene un doble objetivo.

Abstract: Body Mass Index (BMI) is a measurement of nutritional status by calculating the ratio of height and weight. Type 2 Diabetes Mellitus (T2DM) is more common in a person with a BMI of more than normal. In patients with T2DM, there is lipid metabolism disorder, dyslipidaemia. Changes in lipid profiles consist of increased levels of total cholesterol, Low Density Lipoprotein (LDL), and triglycerides, and decreased levels of High Density Lipoprotein (HDL). This study aimed to obtain the correlation between body mass index and lipid profile in T2DM patients in Prof. Dr. R. D. Kandou Hospital Manado. This was a descriptive analytical study using patients’ medical record in Endocrine Clinic Prof. Dr. R. D. Kandou Hospital Manado from September to November 2015. The Pearson correlation test showed correlations between BMI and total cholesterol levels with r=0.037and p=0.763; between BMI and HDL levels with r=-0.249 and p=0.039; between BMI and LDL levels with r=0.091 and p=0,455; and between BMI and triglyceride levels with r=0.179 and p=0.142. Conclusion: Among T2DM patients, there were no significant correlations between body mass index and total cholesterol, LDL cholesterol, as wello as triglyceride levels. However, there was a significant correlation between body mass index and HDL levels.

Objective: Endothelial cell (EC) dysfunction is a well-established response to cardiovascular disease risk factors, such as smoking and obesity. Risk factor exposure can modify EC signaling and behavior, leading to arterial and venous disease development. Here, we aimed to identify biomarker panels for the assessment of EC dysfunction, which could be useful for risk stratification or to monitor treatment response. Approach and Results: We used affinity proteomics to identify EC proteins circulating in plasma that were associated with cardiovascular disease risk factor exposure. Two hundred sixteen proteins, which we previously predicted to be EC-enriched across vascular beds, were measured in plasma samples (n=1005) from the population-based SCAPIS (Swedish Cardiopulmonary Bioimage Study) pilot. Thirty-eight of these proteins were associated with body mass index, total cholesterol, low-density lipoprotein, smoking, hypertension, or diabetes. Sex-specific analysis revealed that associations predominantly observed in female- or male-only samples were most frequently with the risk factors body mass index, or total cholesterol and smoking, respectively. We show a relationship between individual cardiovascular disease risk, calculated with the Framingham risk score, and the corresponding biomarker profiles. Conclusions: EC proteins in plasma could reflect vascular health status.

Background: Adolescents and ethnic subgroups have been identified at high risks of overweight and its associated complications. Although some studies have investigated overweight, obesity, nutritional status, physical activity, and associated factors among Saudi students, no studies have examined these characteristics among non-Saudi students or compared non-Saudi to Saudi adolescent students. The objective of this study was to compare differences between Saudi and non-Saudi adolescent students regarding time spent watching television, using computers, engaging in physical activity, and their food preferences. The relationships between these lifestyle behaviors and body mass index by Saudi nativity and gender were tested. Methods: Students aged 12 to 18 years (n = 214) from various schools in Riyadh, Saudi Arabia, completed a self-administered questionnaire that included questions about demographic and anthropometric characteristics, daily after-school routine, physical activity, watching television, using computers, and food preferences. Non-parametric (Mann–Whitney U) tests assessed the statistical differences between Saudi and non-Saudi respondents, and males and females were separately tested. Results: Saudi boys who reported physical activity two to five times per week, the most television time, the most computer time, and the highest frequency of eating fast food and drinking soft drinks had a significantly higher mean body mass index than the non-Saudi boys in their categories. However, there were no significant differences found between the Saudi and non-Saudi girls. Conclusions: High levels of sedentary and low levels of physical activities as well as high consumption of high-fat fast foods and high-sugar drinks threaten the health of Saudi adolescents. Cultural differences in lifestyle between Saudi and non-Saudi families should be considered when developing programs to improve knowledge, attitudes, and behaviors regarding diet quality and physical activity. The objective of this study is more important in the current situation where increased time spent on computers and mobile phones due to online teaching in schools or working from home, decreased physical activity due to precautionary lockdowns, and unchecked eating patterns while spending more time in sedentary activities in homes has become our COVID-19 pandemic lifestyle in all the age groups. A similar study should be replicated on a large scale to study the effect of this lifestyle on our lives in all the age groups.

Aerobic and resistance exercise have been prescript to prevention and non pharmacological treatment of hypertension. However, there is a lack of studies investigating the effects of concurrent training in hypertensive women. Thus, the aim of this study was to investigate the effects of concurrent training program on rest blood pressure, biochemical variables (blood glucose and total cholesterol) , anthropometric (body mass index and waist circumference) and functional fitness in hypertensive women. Eighteen hypertensive postmenopausal and untrained women (59±12 years old) started in the intervention, but only ten subjects finished. The voluntaries were enrolled in concurrent training, 60 min/day, 3 times a week, during 6 months. Systolic and diastolic blood pressure, blood glucose, total cholesterol, body mass index, waist circumference and functional fitness (AAPHERD) were measured pre and post experimental period. Data were analyzed using the Student’s t test with significance level set at 5% (P?0.05) and Cohen's Effect Size (ES). The results showed significant improvement in systolic and diastolic blood pressure at rest. The other variables did not show significantly changes, but the ES was medium and large for several variables (body mass index, blood glucose, total cholesterol, agility, coordination, aerobic fitness, strength endurance and general functional fitness index). In conclusion, this study confirms that 6 month of concurrent training program improved systolic and diastolic blood pressure in hypertensive women. In addition, the protocol suggests an improvement in anthropometric, biochemical and functional variables related to health.

Few studies examine the association between serum uric acid (SUA) and acute coronary syndrome (ACS). We aimed to investigate the association between SUA and ACS in a prospective study of ethnic Chinese. Enrolled were 128569 adults ≥ 20 yrs from 4 MJ Health Checkup Clinics in Taiwan during 1994 –1996, excluding those with heart disease, stroke, renal disease and cancer disease. All physical examination, biochemical test and structured questionnaire were executed in standardized central labs. ACS was defined by main ICD-9 of 410 – 414 from claim data of National Health Insurance for hospitalization and from Death certification registry. Cox proportional hazard model was used to estimate the hazard ratios (HRs) between levels of SUA and ACS events. A total of 2049 subjects (Men: 1239/Women: 810) developed ACS during the period from baseline to Dec.31.2002. Men had higher ACS incidence than women (2.84 vs. 1.61 per 1000 person-years [PY]; p < .0001). Independent risk factors of ACS unfolded from this study included age, male sex, waist circumference, body mass index, triglycerides, total-cholesterol, hypertension, diabetes, uric acid, and current smoking. The crude incidences of ACS were 1.27, 2.06, 3.27 and 4.61 per 1000 PY in that order for four consecutive SUA groups (group1: <5.0 mg/dl; group 2: 5.0 – 6.9 mg/dl; group 3: 7.0 – 8.9 mg/dl; group 4: ≥9.0 mg/dl) (p-value for trend <.0001). Compared to group1, the multi-variate adjusted HRs (95% Confidence intervals) were 1.14 (0.92, 1.42) for group 2, 1.38 (1.10, 1.72) for group 3 and 1.38 (1.10, 1.72) for group 4 among men, and 1.03 (0.87, 1.22), 1.30 (1.05, 1.62) and 1.43 (0.99, 2.05) among women after adjusting for age, systolic/diastolic BP, body mass index, triglycerides, total cholesterol, diabetes, smoking, alcohol drinking, physical activity, and occupation. One standard deviation increase in SUA corresponded to around 30% ACS risk increase in women (HR=1.33; 1.04 –1.70) and 60% in men (HR=1.59; 1.25–2.03). Baseline SUA level independently predicts the development of ACS and should be considered as a potential risk factor of ACS.

In our society, childhood obesity has become a pressing health issue. Childhood obesity occurs when children are considerably overweight for their age and height. Body mass index (BMI) is used to measure the percentage of body fat; therefore, the higher the BMI, the more body fat an individual has accompanied by the likelihood that the individual is obese. This research aims to address the factors that cause childhood obesity. A total of 116 journal articles were used for the development of this paper; the articles were analyzed and selected based on the occurrence of the following keywords and phrases: (1) childhood obesity, (2) social cognition theory, (3) telemedicine, and (4) nutrition education. The literature review showed a relationship between childhood obesity and body mass index (reduction, the use of telemedicine, and school food gardens). Using telemedicine video conferencing software and adding food gardens to public school curricula may be a strategy educators and policymakers can use to reduce the rate of childhood obesity.
