The Relevance of Plant-Based Diets and Micronutrient Supplementation for Body C...
Pinheiro, C; Silva, F; Rocha, I; Martins, C; Giesteira, L; Dias, B; Lucas, A; Alexandre, AM; Ferreira, C; Viegas, B; Bracchi, I; Guimarães, J; Amaro, J"Objectives: This study aimed to compare the anthropometry and body composition of vegetarian and omnivorous adults living in Portugal, while exploring nutritional and health parameters underlying observed differences. Methods: 425 omnivorous (OMNI), lacto-ovo-vegetarian (LOV), or vegan (VEG) healthy adults were recruited. Anthropometry was measured, and bioelectrical impedance analysis was performed. Participa...
Are hypohydrated older adults at increased risk of exhaustion?
Anjo, I; Amaral, TF; Afonso, C; Borges, N; Santos, A; Moreira, P; Padrão, PBackground: Dehydration appears to affect muscle strength and weakness, although its influence on exhaustion remains unclear. The present study aimed to quantify the association between hydration status and exhaustion among older adults. Methods: A cluster sampling approach was used, representing Portuguese older adults (≥65 years) according to age, sex, education level and region within the Nutrition UP65 cros...
Sitting time and associated factors among Portuguese older adults: results from...
Sousa, AS; Mendes, J; Guerra, RS; Padrão, P; Moreira, P; Santos, A; Borges, N; Afonso, C; Martins, C; Ferro, G; Amaral, TFOlder adults are particularly susceptible to sedentary behaviours. Sitting time has been increasingly referred to as a potentially modifiable risk factor in the prevention of chronic diseases. Identifying factors associated with sitting time, particularly those that are modifiable, will allow for more effective public health strategies. This study aimed to describe sitting time among Portuguese older adults and...
Adherence to a Mediterranean Dietary Pattern and Functional Parameters: A Cross...
Mendes, J; Afonso, C; Borges, N; Santos, A; Moreira, P; Padrão, P; Negrão, R; Amaral, TFObjectives: In older adults, diet and physical activity are among the most important behaviours that influence health. The Mediterranean Dietary Pattern has been related to longevity and can benefit physical function in older adults. The present study aims to quantify the association of adherence to a Mediterranean Dietary Pattern with physical functioning through by handgrip strength, as well as, with sedentar...
Nutritional and Functional Indicators and Their Association With Mortality Amon...
Sousa, OV; Mendes, J; Amaral, TFThis study investigated how different nutritional and functional status indicators are associated with mortality in patients with Alzheimer’s disease (AD). A prospective cohort study was conducted among 79 community-dwelling older adults with AD. Follow-up was 60 months. Undernutrition status was evaluated by Mini Nutritional Assessment (MNA), body mass index, mid-arm muscle circumference (MAMC), calf circumfer...
Nutritional status and gait speed in a nationwide population-based sample of ol...
Mendes, J; Borges, N; Padrão, AP; Moreira, P; Afonso, C; Negrão, R; Amaral, TFThe association between nutritional status and gait speed remains unclear. This study described gait speed in older adults and quantified the association between overweight, obesity, undernutrition risk and gait speed. Gait speed as potential indicator of nutritional outcomes was also explored. A cross-sectional analysis was conducted in a population-based sample of 1,500 older adults ≥65 years old. Compared to...
Undernutrition risk at hospital admission and length of stay among pulmonology ...
Maia, I; Xará, S; Vaz, D; Shiang, T; Amaral, TFBackground: There is a lack of evidence regarding the association between the undernutrition risk at hospital admission with adverse clinical outcomes amongst pulmonology inpatients. The aim of this study was to quantify the association between undernutrition risk at hospital admission and time to discharge alive. Methods: A retrospective cohort study including patients consecutively admitted to a pulmonology u...
Weakness: The most frequent criterion among pre-frail and frail older Portuguese
Sousa-Santos, A; Afonso, C; Moreira, P; Padrão, P; Santos, A; Borges, N; Amaral, TFAim In Portugal, the burden of pre-frailty and frailty in community-dwelling older adults is still unknown. The purpose of this study is to estimate the frequency of frailty in a Portuguese sample with = 65 years and to evaluate its associated factors. We also intend to identify which criterion has more impact on the diagnosis of frailty. Methods 1457 older adults with = 65 years from the Nutrition UP 65 study ...
The effect of posture on body circumferences in older adults
Sousa, AS; de Sousa, OL; Amaral, TFBackgroundStandards for anthropometrical assessment define that measurements must be carried out with the subject in the standing position, although this is not always possible. The effect of body position on girth measurement has not been evaluated, even though this issue is clinically relevant because it may bias nutritional assessment results. The present study aimed to evaluate the effect of body position a...
Comparison of nutritional status assessment parameters in predicting length of ...
Mendes, J; Alves, P; Amaral, TFBackground & aims: Undernutrition has been associated with an increased length of hospital stay which may reflect the patient prognosis. The aim of this study was to quantify and compare the association between nutritional status and handgrip strength at hospital admission with time to discharge in cancer patients. Methods: An observational prospective study was conducted in an oncology center. Patient-Generate...
