Objective: The aim of the study was to investigate the blood pressure variability during 24 h by using ambulatory blood pressure monitoring (ABPM) in a group of obese and non-obese female adolescents with breast development status 4 and 5 of Tanner's criteria. Methods: A cross-sectional study was conducted at the Cardiovascular Research Institute, Mexico. All subjects underwent 24 h non-invasive ABPM recording device. Pubertal status was determined by breast development. Measurements: office systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR). Height, weight, body mass index (BMI), waist and hip circumferences, arm circumference, waist to hip ratio (W/H), and skinfold thickness measurements: triceps, subscapular, abdominal and supraspinal. Results: Fifty-nine adolescents 13-16 years old; 29 obese (BMI 31.2 ± 4.0), and 30 non- obese (BMI 21.2 ± 2.2). Obese vs. non-obese: Office SBP 116.9 vs. 105.9 ± 9.3 mmHg (p < 0.001); ABPM in 24 h: SBP 113.8 ± 6.3 vs. 107.6 ± 5.7 mmHg (p < 0.001); diurnal SBP 117.3 mmHg vs. 111.2 mmHg (p < 0.001); nocturnal SBP 105.5 ± 8 vs. 99.4 mmHg; absolute variability in 24 h DBP 10.0 ± 1.8 vs. 8.7 ± 1.5 (p < 0.003); coefficient of variation 24 h DBP 17.3 ± 3 vs. 15.4 ± 2.6% (p < 0.05); systolic non-dipper 16 (55.2%) vs. 9 (30%) (p < 0.05); pulse pressure 24 h 49.3 ± 8 vs. 43.5 ± 9 mmHg (p < 0.01). Conclusion: Obese adolescents are presenting changes in BP variability during 24-h in comparison with non-obese adolescents; it also includes higher pulse pressure. Thus, these can be early indicators for the development of hypertension or other cardiovascular diseases in the adult life.

Objective: To explore food habits, demographic and socioeconomic factors associated to calcium intake of pregnant adolescents.Methods: In a cross sectional study 321 participants of 13 to 19 years old attending to the division of gynecology- obstetrics of the Civil Hospital of Guadalajara were included. All participants were healthy, in any moment of pregnancy and belonging to the low and middle-low socioeconomic status. The calcium intake was obtained through a food frequency questionnaire and a 24-hour dietary recall. Demographic and socioeconomic data were also included. A chi square test, an odds ratio (95% CI) and a regression logistic model for the identification of the epidemiologic meaning of the associated variables to the calcium intake were obtained.Results: Sixty one percent of adolescents consumed less that 80% of the diary recommended intake of calcium. The domestic labor occupation of adolescents [OR 2.66 (1.28-5.53)], low milk [OR 2.54 (1.37-4.0)] and dairy intake [OR 2.75 (1.09-7.0)], excess of carbonated beverages consumption [OR 1.84 (1.04-3.28)] and low literacy of mothers [OR 1.83 (1.15-2.90)] were the most epidemiological meaning factors associated to deficient calcium intake.Conclusion: The results suggest that the calcium intake was deficient in the majority of pregnant adolescents and that there are some risk factors that must be identified and attended. Likewise, it is necessary to evaluate the nutritional status of calcium in this especial group with more precise and specific methods. © 2014, Grupo Aula Medica S.A. All rights reserved.

The purpose was to evaluate the association between calcium (Ca) intake and adiposity in adolescents. A cross-sectional study of 125 adolescents 12 to 16 years. Ca intake was evaluated by 24-hour recall dietary surveys and food frequency consumption. Adiposity was measured by anthropometric methods and bioelectrical impedance (BIA). The association between Ca intake and adiposity was identified by simple correlation and multivariate models adjusted to energy consumption, age, sex and menarche. Mean age of adolescents was 13.5 ± 0.8 years. A negative correlation was identified between Ca intake and anthropometric indicators weight, skinfolds, body mass index, fat mass and percentage of fat (the latter two by BIA and only in women). Multivariate analysis, including energy consumption showed no association between Ca intake and adiposity. In conclusion, Ca consumption does not associate with adiposity in adolescents; multivariate models showed that energy intake and menarche are the variables that show a higher association with adiposity at this stage of life.

The objective was to assess the nutritional status and its association with dyslipidemia in adolescents 12 to 18 years in a rural school of Zapopan, Jalisco. Methods and materials. In a cross-sectional study 281 subjects were included. A food frequency intake survey was conducted and anthropometric measurements. Serum lipid profile was determined in overweight or obese subjects. Results. 48 cases (17.1%) were overweight (body mass index percentile 85 to > 97) and 64 (22.8%) were obese (body mass index percentile ≥ 97). The most common abnormality of the lipid profile was hypertriglyceridemia in 38%, followed by elevation of low density lipoprotein in 9% and low levels of high density lipoprotein in 6%. There were no differences in the lipid profile in subjects with overweight or obesity. Conclusions. The presence of dyslipidemia was not so common in this group of patients who are overweight or obese. Some reports in Mexico have shown a higher frequency of dyslipidemia, particularly changes in high density lipoprotein.

Background. It has been demonstrated that indirect indicators of adiposity such as body mass index are associated with metabolic disorders including cardiovascular risk factors. The objective was to evaluate the association of body mass index (BMI) and waist circumference (WC) with cardiovascular risk factors in obese children and adolescents. Methods. Cross-sectional study in 115 obese children and adolescents (BMI >+ 2.0 SD). Weight, height and waist circumference were measured. Blood pressure (BP), serum lipid profile, glucose and insulin were determined and HOMA-IR index was calculated. The correlation between BMI and WC with biochemical parameters and BP was identified; multivariate models were performed to evaluate the association of BMI and WC with cardiovascular risk factors. Results. Mean age was 9.75 ± 3.1 years. A significant positive correlation of BMI and WC with BP, insulin and HOMA-IR was identified. In multivariate models, both BMI and WC showed an association with these alterations. Conclusions. In obese children and adolescents, both the WC and BMI are associated with alterations in BP, insulin and HOMA-IR.
