Association between adiposity and emergent depressive symptoms in a 10-years prospective cohort of older adults: The EpiFloripa Aging study.

BACKGROUND: The association between obesity and depressive symptoms has been described in the literature, but there is a scarcity of longitudinal data. This study aimed to verify the association between body mass index (BMI) and waist circumference and the incidence of depressive symptoms over a 10-year follow-up in a cohort of older adults. METHODS: Data from the first (2009-2010), second (2013-2014), and third (2017-2019) waves of the EpiFloripa Aging Cohort Study were used. Depressive symptoms were assessed by the 15-item Geriatric Depression Scale (GDS-15) and classified in significant depressive symptoms for those with ≥6 points. The Generalized Estimating Equations model was used to estimate the longitudinal association between BMI and waist circumference and depressive symptoms across a 10-year follow-up. RESULTS: The incidence of depressive symptoms (N = 580) was 9.9 %. The relationship between BMI and the incidence of depressive symptoms in older adults followed a U-shaped curve. Older adults with obesity had an incidence relative ratio of 76 % (IRR = 1.24, p = 0.035) for increasing the score of depressive symptoms after 10 years, compared to those with overweight. The higher category of waist circumference (Male: ≥102; Female: ≥88 cm) was associated with depressive symptoms (IRR = 1.09, p = 0.033), only in a non-adjusted analysis. LIMITATIONS: Relatively high follow-up dropout rate; Few individuals in the underweight BMI category; BMI must be considered with caution because it does not measure only fat mass. CONCLUSIONS: Obesity was associated with the incidence of depressive symptoms when compared with overweight in older adults.

Effects of Euterpe edulis Martius on inflammatory responses to high-intensity intermittent exercise: Crossover randomized trial.

OBJECTIVE: High-intensity intermittent exercise (HIIE) may enhance the antiinflammatory status. The juçara fruit juice (JFJ) has well-established antioxidant and antiinflammatory properties. This study investigated the effect of JFJ consumption on the inflammatory response to HIIE in physically active subjects. METHODS: In a randomized crossover design, 15 men were assigned to drink 250 mL of either JFJ or water (control) 1 h before a cycling HIIE session (seven sets of 60 s at 100% peak power output; 75 s recovery between sets). Blood samples were obtained before and at 0, 30, and 60 min post-HIIE, and the serum was analyzed for interleukin (IL)-6, IL-1ß, IL-8, IL-10, tumor necrosis factor-α, and cortisol. RESULTS: After HIIE, the IL-6 levels were higher than baseline (percent change) at 30 min (P = 0.041) and 60 min (P = 0.038) for the control, but were unaffected by JFJ. IL-10 was higher in the JFJ group than in the control at 30 min (d = â€’0.63). Tumor necrosis factor-α was lower than baseline at 30 min for the control (d = â€’0.71) and at 60 min for the JFJ group (d = â€’0.60). For control, cortisol increased to higher than the baseline at 30 and 60 min (d = 0.54 and d = 0.76, respectively). For the JFJ group, the cortisol levels were significantly higher than the baseline at 30 min (P = 0.022). Performance during sprints was higher in the JFJ group than in the control (P = 0.002). In the control group, performance was with both IL-6 (semipartial correlation; sr = -0.59, large effect size) and cortisol at 0 h (sr = -0.52, large effect size). CONCLUSIONS: JFJ intake attenuated the antiinflammatory response to HIIE, possibly resulting from a lower degree of muscle stress.

Nutritional challenges in older adults during the COVID-19 pandemic / Desafios nutricionais na saúde de idosos em tempos de pandemia da COVID-19

ABSTRACT It has been documented that the older adults of the population are at the greatest risk of mortality due to the coronavirus disease; consequently, they could be the population most affected by the measures of social isolation and reduction of virus contagion implemented worldwide. Social isolation can expose older adults to an increased nutritional risk due to factors such as socioeconomic insecurity, which could affect food acquisition and the need for support in daily tasks and meals. The institutionalized older adults often depend on food donations, which may have reduced due the economic crisis caused by the pandemic, and the aging process itself causes changes in nutritional necessitie and eating habits. In the coronavirus pandemic, nutritionists and dietitians can offer remote nutritional follow-up. Moreover, the government actions, such as the implementation of educational and social service programs, should be applied to support healthy aging and minimize exposure to nutritional risks and coronavirus disease.

RESUMO Tem sido documentado que os idosos são a população de maior risco para mortalidade por COVID-19. Consequentemente, pode ser a mais afetada pelas medidas de isolamento social e de redução de contágio pelo vírus implementadas em todo o mundo. O isolamento social pode expor os idosos ao risco nutricional aumentado devido a alguns fatores, como: a insegurança socioeconômica, a qual pode afetar a aquisição de alimentos; a necessidade de apoio nas tarefas e nas refeições diárias; a possível redução de doações de alimentos para idosos institucionalizados, em virtude da crise econômica ocasionada pela pandemia; e o próprio processo do envelhecimento, que causa alterações das necessidades nutricionais e do hábito de se alimentar. Contudo, no contexto da pandemia do novo coronavírus, nutricionistas podem oferecer acompanhamento nutricional remoto. Além disso, ações governamentais, como a implementação de programas educacionais e de serviço social, devem ser aplicadas para o envelhecimento saudável e para a minimização da exposição ao risco nutricional e à COVID-19.
