    Comparison of Diagnostic Models to Estimate the Risk of Metabolic Syndrome in a Chilean Pediatric Population: A Cross-Sectional Study

    The pediatric population has various criteria for measuring metabolic syndrome (MetS). The diversity of consensus for diagnosis has led to different non-comparable reported prevalence. Given the increase in its prevalence in pediatric ages, it is necessary to develop efficient methods to encourage early detection. Consequently, early screening for the risk of MetS could favor timely action in preventing associated comorbidities in adulthood. This study aimed to establish the diagnostic capacity of models that use non-invasive (anthropometric) and invasive (serum biomarkers) variables for the early detection of MetS in Chilean children. A cross-sectional study was carried out on 220 children aged 6 to 11. Multivariate logistic regressions and discriminant analyses were applied to determine the diagnostic capacity of invasive and non-invasive variables. Based on these results, four diagnostic models were created and compared: (i) anthropometric, (ii) hormonal (insulin, leptin, and adiponectin), (iii) Lipid A (high-density cholesterol lipoprotein [HDL-c] and triglycerides [TG]) and (iv) Lipid B (TG/HDL-c). The prevalence of MetS was 26.8%. Lipid biomarkers (HDL-c and TG) and their ratio (TG/HDL-c) presented higher diagnostic capacity, above 80%, followed by body mass index (BMI, 0.71-0.88) and waist-to-height ratio (WHtR, 0.70-0.87). The lipid model A was the most accurate (sensitivity [S] = 62.7%, specificity [E] = 96.9%, validity index 87.7%), followed by the anthropometric model (S = 69.5%, E = 88.8% and validity index = 83.6%). In conclusion, detecting MetS was possible through invasive and non-invasive methods tested in overweight and obese children. The proposed models based on anthropometric variables, or serum biomarkers of the lipid model A, presented acceptable validity indices. Moreover, they were higher than those that measured adipokines, leptin, and adiponectin. The anthropometric model was the most cost-effective and easy to apply in different environments.

    Handgrip strength as a predictor of adverse health outcomes
    (2022) Concha-Cisternas, Yeny; Petermann-Rocha, Fanny; Castro-Pinero, Jose; Parra, Solage; Albala, Cecilia; Van De Wyngard, Vanessa; Vasquez, Jaime; Cigarroa, Igor; Celis-Morales, Carlos
    Muscle strength can be measured through different methods and handgrip strength is one of the most used techniques in epidemiological studies. Given its easy application, high reliability, and low cost, it is considered an important health biomarker. Handgrip strength is associated with adverse health outcomes such as mortality and risk of developing chronic diseases, cardiovascular, respiratory, cancer and dementia. There is a paucity of evidence in Chile about the association of handgrip strength with these health outcomes limiting its visibility and implementation in clinical settings. Therefore, this narrative review summarizes the scientific evidence about the association of grip strength with non-communicable chronic diseases and mortality in middle age and older adults.

    Sex disparities in gallstone disease: insights from the MAUCO prospective population-based cohort study
    (2024) Gatta, Danae Rodriguez; Huidobro, Laura; Petermann-Rocha, Fanny; Van de Wyngard, Vanessa; Godoy, Franco; Cid, Vicente; Garrido, Macarena; Cook, Paz; Roa, Juan Carlos; Vargas, Claudio; Araya, Juan Carlos; Cortes, Sandra; Cruz, Francisco; Koshiol, Jill; Arrese, Marco; Ferreccio, Catterina
    Objective To investigate factors associated with the prevalence and incidence of gallstone disease (GSD) in women and men of the MAUCO population-based prospective cohort. Design 8948 MAUCO participants (aged 38-74 years) underwent abdominal ultrasound at baseline (2015-2019); 4385 received follow-up ultrasound at years 2 or 4. Factors associated with prevalent GSD were assessed using Poisson multiple regression and with incident GSD using Cox regression models. Results GSD prevalence was 40.4% in women (13.1% gallstones, 27.3% cholecystectomies) and 17.1% in men (8.9% gallstones, 8.2% cholecystectomies). In men, GSD prevalence rate ratio (PRR) by age in >64 years was 3.85 (95% CI 3.00 to 4.94), doubling that of women's PRR 1.78 (95% CI 1.57 to 2.01). In women, waist circumference and diabetes were stronger GSD factors; a higher number of children and worse metabolic and socioeconomic conditions were also highlighted. GSD men had higher cardiovascular disease and a family history of GSD and gallbladder cancer. 198 GSD cases developed during follow-up, with incidence increasing by 2% (95% CI 1.005% to 1.03%) per each centimetre above the ideal waist circumference, statistically significant only in women. In men, age was the strongest factor for incidence, followed by a family history of GSD and low high-density lipoprotein increased incidence risk. Conclusions GSD burden was high in this population; a third of women had their gallbladder removed, which may pose them at risk of other health problems. Abdominal obesity was the only preventable GSD risk factor, highlighting the need for effective public health policies promoting obesity reduction.
