Overweight and obesity result from change in dietary patterns and increasingly sedentary attitude. Objectives: To compare the energy and nutrient intake in female adolescents with overweight and obesity. Design: Cross-sectional, observational and analytical study. Location: Lima’s urban area Education Center. Participants: Adolescents aged 10 to 18 years. Interventions: One hundred overweight adolescents and 87 obese adolescents were studied. Diagnosis was done by body mass index (BMI) with the World Health Organization (WHO) reference population and cutoff levels between 85 and 95 percentile for overweight and over 95 for obesity. Amount of energy and nutrients was determined by a semi quantitative food frequency questionnaire using the Peruvian Table for Food Composition and the Table of the USA Department of Agriculture. FAO recommendations were used to determine the adequate percen...

Overweight and obesity lead the occurrence of comorbidities such as type 2 diabetes mellitus, hypertension, anddyslipidemias. Objectives: To determine the presence of cardiovascular risk in children and adolescents overweight and obese,by gender and age groups. Design: Cross sectional study. Participants: Children and adolescents of both genders, 5-18 year-old.Interventions: Diagnosis of overweight and obesity was done according to Must et al. classification with the following criteria: 85 to 95for overweight and more than 95 percentile for obesity. Serum lipid profile, glucose and insulin were analyzed, and with the latter twoHOMA index was determined to identify insulin resistance (IR), using Matthew´s equation, the metabolic syndrome (MS) with referenceto Cook and dyslipidemias (D) with Friedman and Daniels’ suggestions. Main outcome measures: Cardiovascular risk. Results: Obesechi...

Introduction: Obesity is a public health problem that tends to increase and compromises the health of people. Objectives: To determine the prevalence of metabolically normal obese (OMN) subjects depending on the presence of cardiovascular risk factors in an adult population showing obesity and morbid obesity. Design: Observational, descriptive and cross-section study. Setting: Department of Endocrinology, Hospital Dos de Mayo, Lima, Peru. Participants: Obese adults without metabolic diseases. Interventions: the study was conducted during the period between April 2009 and May 2010 in all adults consulting for obesity and who declared not having type 2 diabetes mellitus, arterial hypertension or dyslipidemia. Weight, height and waist circumference (WC) were obtained, and body mass index (BMI) was calculated. Those who had 30 kg/m2 or more were included in the study. Insulin, glucose and li...

Introduction: Teenagers represent somehow a fifth of the population and are not away from nutritional problems. Objectives: To determine the nutritional status, growth and some determining factors in adolescents in Peru. Design: Descriptive, observational, transversal study. Participants: Adolescents. Interventions: Weight, height, body mass index were obtained from 14 753 adolescents 10-19 yearold. Must percentile reference and WHO Z score were used. Main outcome measures: Averages and DE, prevalence CI 95%, OR IC 95%, chi-square and multiple regressions were obtained. Results: Prevalence of deficit, underweight, normal, overweight and obesity found respectively were 2.6; 5.9; 79; 9.3 and 3.2 (Must); 0.2; 1.1; 82.6; 12.5; 3.5% (WHO). Overweight- obesity predominated in urban areas, in non-poor areas , the coast, jungle and Metropolitan Lima,and in those lived below 3 000 masl. Risk fact...

Introduction. Vitamin deficiency is being considered a public health problem. Objectives. To describe vitamin D status in female adolescents with obesity. Design. Observational, descriptive, analytical study. Location. Metropolitan Lima. Participants. Teenagers. Interventions. According to body mass index, 111 adolescents were studied, 58 were obese and 53 non-obese. A food survey was performed including those containing vitamin D and vitamin supplements. Waist circumference and blood pressure were obtained. Glucose, lipid profile and 25 hydroxyvitamin D were determined in serum. Vitamin D status was determined by Holick criteria. Statistical analysis used student-t test, chi-square and ANOVA, with a 95% confidence interval and a significance level of <0.05. Main outcome measures. Averages, confidence interval and prevalence. Results. Vitamin D deficiency (<20 ng/mL) was found in 1...

OBJECTIVE.- To determine the nutritional status Of pregnant adolescents. PATIENTS: We studied 177 pregnant adolescents 15 to 19 years of age, attended at Dos de Mayo and Santa Rosa Hospitals. Weight and height were taken to the entire population. Arm perimeter and triceps skinfold thickness were measured to 56 patients. With the first two, the Quetelet index was calculated and with the latter ones the muscular and fat areas. For the IQ analysis the Must et al reference was used; arm ratios were analyzed with Frisancho's reference. In 56 adolescents Hb was dosed (11 gr/dL). Their quantitative consumption of energy and nutrients was appraised to 54. RESULTS: Anemia was found in 62,5% of the pregnant adolescents. No supplementation is received by 77% of them; 10% of the pregnant show low weight during the first trimester. About 6 to 8% show a light decrease in their ratios of fat and magre...
