- PublicaciónSólo datosAssociation between serum vitamin B12 levels and metabolic syndrome in a euthyroid population(Diabetes India, 2018-05) Guarnizo-Poma, Mirella; Urrunaga-Pastor, Diego; Montero-Suyo, Cory; Lazaro-Alcantara, Herbert; Paico-Palacios, Socorro; Pantoja-Torres, Betzi; Benites Zapata, Vicente A.Aims: To determine the association between serum levels of vitamin B12 and metabolic syndrome (MetS) in a population of euthyroid adults. Materials and methods: We carried out an analytical cross-sectional study in euthyroid adults of both sexes, who attended the outpatient service of a private clinic in Lima-Peru during the 2012–2016 period. Participants were divided into tertiles (low, intermediate and high) according to their serum vitamin B12 values. MetS was defined when three or more metabolic criteria were met by the participants. We elaborated crude and adjusted Poisson regression models to evaluate the association between the serum vitamin B12 tertiles and the presence of MetS. The reported association measure was the prevalence ratio (PR) with their respective 95% confidence intervals (95%CI).
- PublicaciónAcceso abiertoFactors associated with poor physical performance in older adults of 11 Peruvian high Andean communities(F1000 Research Ltd., 2019-01) Urrunaga-Pastor, Diego; Runzer-Colmenares, Fernando M.; Arones, Tania M.; Meza-Cordero, Rosario; Taipe-Guizado, Silvana; Guralnik, Jack M.; Parodi, Jose F.Background: Physical performance in the older adult has been extensively studied. However, only a few studies have evaluated physical performance among older adults of high Andean populations and none have studied the factors associated with it. The objective of this study was to evaluate factors associated with poor physical performance by using the Short Physical Performance Battery (SPPB) in older adults living in 11 Peruvian high Andean communities. Methods: An analytical cross-sectional study was carried out in inhabitants aged 60 or over from 11 high-altitude Andean communities of Peru during 2013-2017. Participants were categorized in two groups according to their SPPB score: poor physical performance (0-6 points) and medium/good physical performance (7-12 points). Additionally, we collected socio-demographic, medical, functional and cognitive assessment information. Poisson regression models were constructed to identify factors associated with poor physical performance. Prevalence ratio (PR) with 95% confidence intervals (95 CI%) are presented.
- PublicaciónSólo datosHigh waist-to-hip ratio levels are associated with insulin resistance markers in normal-weight women(Elsevier Ltd, 2019-02) Benites Zapata, Vicente A.; Toro Huamanchumo, Carlos J.; Urrunaga-Pastor, Diego; Guarnizo-Poma, Mirella; Lázaro-Alcántara, Herbert; Paico-Palacios, Socorro; Pantoja-Torres, Betzi; Ranilla-Seguin, Vitalia Del CarmenAim: To assess the association between high waist-to-hip ratio (WHR) levels and insulin resistance (IR) or hyperinsulinemia after oral glucose tolerance test (OGTT) in a sample of normal-weight women. Methods: We conducted an analytical cross-sectional study in euthyroid non-diabetic women, who attended the outpatient service of a private clinic in Lima-Peru from 2012 to 2016. Participants were divided in two groups according to the presence or absence of high WHR levels, IR or hyperinsulinemia after OGTT. We considered WHR values > 0.85 as high levels. IR was defined as a Homeostasis Model Assessment (HOMA-IR) value > 2.39 and hyperinsulinemia after OGTT as a serum insulin value ≥ 80μU/mL after 120 min of 75-g glucose intake. We elaborated crude and adjusted Poisson generalized linear models to evaluate the association between high WHR levels and IR or hyperinsulinemia after OGTT and reported the prevalence ratio (PR) with their respective 95% confidence intervals (95%CI).
