- Cognitive abilities and physical activity in community-dwelling elderlyPublication . Martins, Emília; Fernandes, Rosina; Mendes, Francisco; Felizardo, Sara; Pocinho, R.; Margarido, C.; Santos, R.; Marques, L.; Trindade, B.; Silva, S.; Gordo, S.There is evidence of the protective role of the regular practice of physical activity (PA) in relation to the aging cognitive decline. A non-exper- imental quantitative study was developed to explore the relationship between physical activity and cognitive abilities in community-dwelling elderly, ana- lysing the relevance of sociodemographic and health related variables. The convenience sample included 546 participants, aged between 63 and 94 years (72.85+6.55), mostly female (69.6%), from the inland of the country (79.5%) and rural areas (68.2%). For data collection, in addition to the sociodemographic questionnaire, the Montreal Cognitive Assessment (MoCA) and the Modified Baecke Questionnaire were used. Statistical analyses (p<.05) were performed using the SPSS-IBM 27. The results point to a positive and significant relationship between the global scores of MoCA and Baecke (r,- 138, p<.02). Self-perception of health was also positively associated with both the MoCA and Baecke global scores (r,- 23 2» p<.001 and r =.204, p<.Oil) and age showed a negative relationship with those two variables (r,- -.294, p<.001 and r,-- *1 3, p<.001). In the association between MoCA and Baecke, the contrast between genders was quite sharp, with males not show ing any statistical relevance (p>.05) in contrast to females (rs=.182, p<.05). Household (living alone or accompanied) showed significant differences in the MOCA, favourable to those living accompanied (U=-3.96, p>.001). In Baecke, only the gender contrast was statistically significant, favourable to females (U= 25395, pt.05). These data are reinforced by scientific evidence and point to policies that promote the practice of physical activity in elderly.
- Nutritional level, health, and subjective well-being in elderlyPublication . Martins, Emília; Fernandes, Rosina; Mendes, Francisco; Pocinho, R.; Margarido, C.; Santos, R.; Marques. L.; Trindade, B.; Silva, S.; Gordo, S.Literature points out the positive association between food, good health, and life satisfaction, manly in elderly. The purpose of this ex post facto quantitative study was to analyse the relationship between nutrition level, health, and subjective well-being, also exploring sociodemographic variables, in a convenience sample of 550 community-dwelling elderly. Participants were between 63 and 94 (72,85+6,56) years-old, mostly female (69,3%), from the inland (79,2%), living accompanied (62,2%) and in rural areas (67,9%). A sociodemographic questionnaire, Mini-Nutritional Assessment, Satisfaction With Life Scale, and Positive and Negative Affect Scales were used in data collection. Data analysis was performed in SPSS 27, assuming a 95% confidence level. Nutritional level was positively correlated with life satisfaction (r,- ,165, p= ,004) and inverse associated with negative affect (r,- -,308, p<,00l). Those who showed a very bad self-perception of health, were older and lived alone, presented lower nutritional levels (p<,05). Participants with health problems showed higher levels of negative affect (p<,001). Elderly with better health self-perception presented higher results in life satisfaction - (•,-271 , p<,001) and positive affect (r,-244, p<,001), contrary to those with worst self-perception of health, who were older (r,- -, 178, p<,001), with higher BMI (r,- - 173, p<,001) and also higher scores in negative affect (r,- -,217, p<,001). The results in our sample confirmed the previous relationship between the variables studied. It emphasizes the assessment of nutritional status and health education, as well as creating policies to promote the practice of physical activity in cities.
