Research on morbidity and mortality often emphasizes individual diseases over the cumulative effects of multimorbidity, especially in low- and middle-income countries. This study aimed to analyze the association between multimorbidity and all-cause mortality in a representative sample of the Chilean population. This longitudinal study used data from 3701 subjects aged ≥15 years who participated in the Chilean National Health Survey conducted between 2009 and 2010. We included 16 self-reported highly prevalent morbidities. All-cause mortality data from an 11-year follow-up were collected from the Chilean Civil Registry. The Cox proportional hazard model, adjusted for confounders, determined the association between multimorbidity categories and all-cause mortality. Of the total sample, 24.3% reported no morbidity, while 50.4% two or more. After adjustment, participants with four or more morbidities had a 1.66 times higher mortality risk [95% confidence interval (CI): 1.03-2.67] than those without morbidities. The mortality risk increased by 10% for each additional morbidity [HR: 1.09 (CI: 1.04-1.16)]. Multimorbidity was common in the Chilean population and increased the mortality risk, which greatly challenges the health system to provide an integral and coordinated approach to healthcare., (© The Author(s) 2023.

Introduction: A Body Shape Index (ABSI) is a new obesity index based on body volume; this has been associated with chronic non-communicable diseases and mortality, independent of the values of the body mass index (BMI); however, its association with type 2 diabetes mellitus (T2DM) in the Chilean adult population is unknown., Objective: To determine the association between ABSI, glycemia, glycosylated hemoglobin (HbAc1), and self-reported T2DM in the Chilean adult population., Materials and Methods: In a cross-sectional study, 4,874 participants were included (mean age 43.3 years, 50.9% women) from the 2016-2017 National Health Survey. ABSI was calculated according to the proposed formula (based on waist circumference, BMI, and height). The Poisson regression was used to investigate the association between ABSI and T2DM, and linear regression was used to investigate the association between ABSI, glycemia, and HbAc1. Sociodemographic factors, lifestyle, and BMI adjusted the analyses., Results: ABSI was positively associated with glycemia (p < 0.001), HbA1c (p < 0.001), and DMT2 (p < 0.001). In the most adjusted model, for every 0.025 unit increase in ABSI, glycemia increased by 1.78 mg/dL (95% CI: 1.21, 2.35) and HbAc1 by 0.92% (95% CI: 0.49, 1.35). Regarding T2DM, the prevalence ratio was 1.14 (95% CI: 1.09, 1.20), independent of sociodemographic factors, lifestyles, and BMI., Conclusions: ABSI was linearly associated with a higher probability of suffering from T2DM and higher levels of glycemia and HbA1c in Chilean adults. In this context, ABSI could be a complementary index, independent of BMI, to assess the risk of metabolic disorders associated with obesity.

Objective: To identify the association between oral health and suspected cognitive impairment in older adults in Chile., Method: Cross-sectional study including 1826 people ≥60 years who participated in the National Health Survey of Chile, 2016-2017. Oral health was evaluated by the number of teeth, presence of caries, use of dental prostheses, self-reported oral health, and pain and/or discomfort in the oral cavity. Cognitive impairment was assessed using the Mini-Mental State Examination (MMSE). The association was evaluated by logistic and linear regression, adjusted for sociodemographic and lifestyle variables., Results: Compared with people without suspicion of cognitive impairment, people with suspected impairment had five fewer teeth (13.4 vs. 8.5 teeth), a much higher difference in women than in men, and a higher frequency of oral pain. Edentulism and fewer teeth were associated with a higher likelihood of suspected cognitive impairment, associations that were not maintained in adjusted models. Oral pain was associated with a higher likelihood of suspected impairment even in the most adjusted model (odds ratio: 1.99; 95% confidence interval [95%CI]: 1.09-3.63). In linear models, an increase of 2% (95%CI: 0.01-0.05) in the MMSE score was observed for each additional tooth., Conclusions: Poor oral health, particularly tooth loss and the presence of pain, was associated with cognitive impairment in older adults in Chile., (Copyright © 2023 SESPAS.

Introduction: Recent studies have shown that low vitamin D levels constitute a potential risk factor for the development of cognitive impairment. The present study aimed to investigate the association between vitamin D levels and the suspicion of cognitive impairment in Chilean older adults., Material and Method: We performed a cross-sectional study, including 1,287 participants ≥ 65 years (56.8% were women, age range 65 to 97 years) from the Chilean National Health Survey. Cognitive impairment was assessed using the Mini Mental State Examination (MMSE). Participants were classified into three groups according to their vitamin D levels (> 29 ng/ml sufficient, 12-29 ng/ml deficit, and < 12 ng/ml severe deficit). The association between vitamin D levels and cognitive impairment was explored using logistic regression analysis, adjusted for confounding factors., Results: The prevalence of vitamin D deficit and vitamin D severe deficit was 37.7% and 21.0%, respectively. Compared to older adults with sufficient levels of vitamin D, those with severe deficits had a 94% (OR: 1.94 [95% IC: 1.27; 1.66], p = 0.002) higher odds of cognitive impairment (unadjusted model). Adjusting according to sociodemographic factors, lifestyle, adiposity, sunlight exposure, and multimorbidity slightly attenuated the association to 61% (OR: 1.61 [95%IC: 1.03; 2.19], p = 0.046), but remain significant., Conclusion: A severe deficit of vitamin D was associated with higher odds of cognitive impairment in Chilean older adults independent of major confounding factors. Future studies are needed to provide causal evidence between vitamin D and the suspicion of cognitive impairment.

This systematic review aimed to assess the available evidence on the effects of neuromuscular training on physical performance in older adults. A literature search was conducted across four databases (Psychology and Behavioral (EBSCO), Scopus, Web of Science and PubMed). The PRISMA guidelines were followed. The PEDro scale and Cochrane risk of bias tool were used to assess the quality of and risk of bias in the studies, respectively. The protocol was registered in PROSPERO (code: CRD42022319239). The outcomes were muscle strength, cardiorespiratory fitness, postural balance and gait speed. From 610 records initially found, 10 were finally included in the systematic review, involving 354 older people with a mean age of 67.3 years. Nine of them reported significant changes in at least one variable related to physical performance in the intervention compared to the control groups. The neuromuscular training caused significant improvements in postural balance, flexibility, cardiorespiratory fitness, strength power of the upper and lower limbs and autonomy. The available evidence indicates that neuromuscular training has a positive effect on some variables of physical performance, especially in postural balance; however, the methodological quality and certainty of the evidence in the available literature are limited. Therefore, a greater number of high-quality studies are required to draw definitive conclusions.
