      Objective: To evaluate the association between waist-to-height-ratio (WHtR) and anxiety in middle age women adjusted by demographic, clinical and habits variables. Methods: We carried out a secondary analysis of data from a multicenter study of women between 40 and 59 years old from 11 Latin America countries. Anxiety was assessed using the Goldberg Anxiety and Depression Scale. WHtR was calculated according World Health Organization standards and was categorized in tertiles: superior, intermediate and inferior with cut points of 0.45 y 0.6; respectively. We calculate prevalence ratios with confidence interval 95% (PR: 95%CI) by generalized linear models of Poisson family with robust standard errors both crude and adjusted models based on statistical and epidemiological criteria. Results: A total of 5580 women were analyzed. The mean age was 49.7±5.5, and 57.9% were postmenopausal. The 61.3% of women had anxiety and WHtR mean was 0.54 ± 0.1. Compared with the women in inferior tertile, the people in the intermediate (PR: 1.07; 95%CI: 1.01-1.13) and superior (PR: 1.23 95%CI: 1.07-1.29) ICT tertile were significantly more likely to have anxiety at the crude model. However, in the adjusted models only women in superior tertil had more probability of anxiety than those in inferior tertile (PR: 1.13 95%CI: 1.08-1.18). Conclusion: In this series, WHtR was associated with anxiety in middle-aged women. It is advisable to incorporate this anthropometric measure in routine clinical practice of climacteric women evaluation.

      Piscoya, Alejandro; Ocampo Mascaró, Javier; Silva Salazar, Vera Jimena; da Costa Bullón, Abilio (Universidad Peruana de Ciencias Aplicadas (UPC), 2015-02-03)
      Introducción. El objetivo del presente estudio es determinar si existe correlación entre los conocimientos sobre las consecuencias de la obesidad y el grado de actividad física de las personas. Métodos. Se realizó un estudio transversal analítico durante los años 2013 y 2014. Participaron 215 alumnos de pregrado seleccionados por conveniencia no relacionados a carreras del campo de la salud en una universidad de Lima, Perú. Se evaluó el grado de actividad física utilizando el International Physical Activity Questionnaire (IPAQ) y el nivel de conocimientos sobre consecuencias de la obesidad utilizando la escala Obesity Risk Knowledge-10 (ORK-10). También, se consignó las fuentes de información de donde obtuvieron el conocimiento para responder dicho cuestionario. Resultados. La mediana de edad fue 20 (rango intercuartílico=4) y 63% eran mujeres. De acuerdo al IPAQ, 53,9% realizaban actividad física alta, 35,4%, moderada y 10,7%, leve. Se encontró una correlación muy baja (rs=0,06) entre el puntaje del ORK-10 y la cantidad de equivalentes metabólicos/minuto consumidos por semana, pero no era significativa (p=0,38). Las personas informadas por medios de comunicación y por personal de salud obtuvieron mayores puntajes en el ORK- 10 que quienes se informaron por otras vías (p<0,05). Conclusiones. La correlación entre los conocimientos sobre consecuencias de la obesidad y el grado de actividad física es muy baja. Es necesario utilizar enfoques multidisciplinarios que incluyan todos los determinantes de la realización de actividad física para poder lograr cambios en la conducta de la población.

    • Duración de lactancia materna e IMC: análisis secundario de la cohorte niños del milenio

      Alvarado, Germán F.; Bravo Chacón, Eva Doris; Arias Meneses, Rodrigo Nicolás Airton (Universidad Peruana de Ciencias Aplicadas (UPC), 20/02/2017)
      Introduction: Studies that have explored the association between duration of breastfeeding(BF) and body mass index (BMI) indicate conflicting results. Objective: Determine the association between duration of BF and BMI in children in the longitudinal cohort "Young Lives" in Peru, Ethiopia, Vietnam and India. Materials and methods: A secondary analysis of "Young Lives" database was made. Data were analyzed for the minor cohort, followed for 12 years through 4 rounds. The nutritional status of the child (outcome) was measured through the Z-Score of the BMI for age and the exposure was the BF in months, measure in the first round. A multiple regression analysis was used to analyze the association between duration of BF and BMI, as well as Generalized Estimating Equations (GLM / GEE) for longitudinal data, considering p<0,05 as significative. Adjusted and unadjusted betas were calculated with 95% CI. Results: 8062 children were studied, with more than 60% of rural origin and 86% born at term. A weak association between duration of BF and Z-Score of BMI was found (beta: -0.01 p<0.05). Thus, children with a longer BF duration would have lower Z-Score BMI values during the follow-up. Conclusions: Despite an inverse association was found between the duration of BF and the outcome, given the weak beta value, it could be type I error. Further studies are needed to elucidate this association, especially in developing countries.

    • Impacto del Índice de Masa Corporal (IMC) con los niveles de Antígeno Prostático Específico (PSA): Revisón sistemática y Meta-análisis

      Ugarte Gil, César Augusto; Canelo Aybar, Carlos Gilberto; Marchena Agapito, Carmen Luz; Urcia Osorio, Stephany Isabel (Universidad Peruana de Ciencias Aplicadas (UPC), 2017-07-05)
      Background: Overweight and obesity have been related with low Prostatic Specific Antigen (PSA); these low levels are due to a bigger plasmatic volume in this population. The objective of this systematic review and meta-analysis is to study the association between BMI and PSA levels. Methods: Three data bases were researched until December 2016, Scopus, PubMed, and Lilacs, using the key words: Prostate-Specific-Antigen, Body Mass Index, Obesity, Humans. We studied healthy male, over 40 years, and with BMI values not older than one month previous the PSA test. Results: 13 studies were used, including cohorts and cross-sectional studies (n=89 942). Overweight and obesity were associated with lower PSA levels compared to eutrophic patients (CC= -0.08; 95%CI -0.11, -0.04; p<0.0001) However, this association was not observed in Nigerian population. Discussion: The inversely proportional relation between BMI and PSA levels was associated with older adults, nevertheless was independent from the race because the association was not observed in Nigerian population. Conclusion: The results of 12 studies supports the literature found about the inversely proportional relation between BMI and PSA levels.

    • Índice de masa corporal asociado al daño en pacientes con Lupus Eritematoso Sistémico del Hospital Nivel IV Guillermo Almenara Irigoyen durante los años 2012- 2015

      Introduction: To determine the association between body mass index (BMI) and damage in patients with systemic lupus erythematosus (SLE). Methods: This is a Cross-sectional analytical study. The main variables were body mass index (BMI) <25 kg/m2 (normal) and ≥25 kg/m2 (overweight and obesity) and damage measured by SLICC-ACR (Systemic Lupus International Collaborating Clinics/American College of Rheumatology) damage index. Other variables were sociodemographic and laboratory features, drug use and subtotal percentage of fat, leg fat, trunk fat and trunk/leg fat ratio. Results: There were studied, 309 patients. Women were 287 (92, 88%) and the average age was 42 ± 12, 98 years. The number of patients with BMI ≥ 25 kg/m2 was 194 (62, 78%). The prevalence of damage was 149 (48, 22%) patients. In the univariate analysis, the variables associated were advanced age, increased year of education, increased disease time, hypertriglyceridemia, hypercholesterolemia, low levels of HDL (<40mg/dl), higher creatinine levels, increased prednisone use, diagnosis of hypertension, actual use of immunosuppressive drugs and higher trunk/leg fat ratio. In the multivariate analysis, the associated variables were advanced age (PR:1,02; CI95%1,01-1,03), actual use of immunosuppressive drugs (PR:1,49; CI95% 1,02-2,19) and greater proportion of fat ratio trunk/leg (PR:1,24; CI95%:1,11-1,39). There was no association between BMI and damage. Conclusions: In the present study, no association between BMI (overweight/obesity) and damage was found. However, we obtained the association with the use of immunosuppressive drugs, higher trunk/leg fat ratio and older age.
