RESUMO
BACKGROUND: To verify whether shorter telomere length is associated with anorexia of ageing in community-dwelling older people. METHODS: Conducted as a cross-sectional investigation, the study enrolled 448 participants residing in an urban area of a municipality in Brazil. Relative telomere length in blood samples was measured using quantitative polymerase chain reaction (qPCR), whereas the presence of anorexia of ageing was determined using the Simplified Appetite Nutritional Questionnaire. Data analysis employed multiple logistic regression. RESULTS: Among the 448 older individuals surveyed, 70.69% were female, and the predominant age bracket ranged from 60 to 69 years (45.08%). Approximately 25% exhibited the shortest telomeric length, with a corresponding anorexia of ageing prevalence of 41.16%. Older individuals with diminished telomere lengths displayed an increased likelihood of experiencing anorexia of ageing (odds ratio [OR] = 1.92; 95% confidence interval [CI] = 1.12-3.29), independent of factors such as gender, age group, depressive symptoms, pain and performance in basic daily life activities. CONCLUSIONS: The observed association between anorexia of ageing and a telomeric biomarker underscores the imperative to meticulously evaluate the nutritional dimensions of older people, with a view to implementing interventions that may enhance their overall health status.
RESUMO
Several factors can impact food consumption in older adults, including those of sociodemographic, physiological, and chronic non-communicable diseases. This study aimed to evaluate the association of food consumption according to its degree of processing with sociodemographic conditions in community-dwelling older adults. Food intake was evaluated from 24-h recall data. All food items were classified according to the degree of processing into four groups as follows: in natura or minimally processed, culinary ingredients, processed, and ultra-processed foods. Food groups were considered dependent variables in a quantile regression model, adjusting for sex, age, schooling, ethnicity, and number of residents. Women and individuals with higher levels of education had lower consumption of in natura or minimally processed foods and higher consumption of ultra-processed foods. The yellow or indigenous ethnicity presented the lowest consumption of processed foods; older people who lived with three or more individuals had the highest consumption of culinary ingredients, whereas the older people who lived with one to two people had the highest consumption of processed foods and the lowest consumption of ultra-processed. These groups may be the target of educational and public policies to improve diet quality and contribute to quality of life in older ages.
RESUMO
BACKGROUND: Anemia is the most common hematological abnormality among older adults, and it is associated with decreased physical performance. But the role of hemoglobin in the absence of anemia remains unclear. Thus, this study aimed to assess the impact of hemoglobin levels on physical performance in Brazilian older adults without anemia. METHODS: The study is longitudinal in that it relies on two waves of the Saúde, Bem-Estar e Envelhecimento (SABE; Health, Well-being, and Aging) study: 2010 and 2015-2016. Mixed-effects linear regression was used to determine the effects of the hemoglobin concentrations on the Short Physical Performance Battery-SPPB over time among the 1,023 who had complete data and did not have anemia in 2010. In the follow-up, there were 567 without anemia. RESULTS: In analyses adjusted for age, education, comorbidities, body mass index, and physical inactivity, we found a differential association between hemoglobin concentration and SBBP by sex, with a positive interaction (ß Hb*female= 0.20, 95% CI 0.04,0.37). At lower levels of hemoglobin, women have lower levels of SPPB than men, but at higher levels of hemoglobin concentration, there are no sex differences in physical performance. In addition, higher age was negatively associated with SPPB levels and cardiometabolic diseases, other diseases, and physical inactivity. Education was positively associated with physical performance. CONCLUSION: Our study demonstrates that higher hemoglobin levels were associated with better physical performance among older adults without anemia in Brazil. However, there were sex differences in this association. This finding is important because, in clinical practice, most health professionals focus on the World Health Organization definition of anemia. Our study suggests the importance of hemoglobin levels among older adults, even those without anemia, and highlights sex differences.

OBJECTIVES: To determine the relationship between social support and mortality in older adults, independent of other health conditions. METHOD: This was a longitudinal study using the database of the 2006 SABE Study (Heath, Well-being and Aging), composed of 1413 individuals aged 60 years and over, living in São Paulo/Brazil. The present study used a questionnaire constructed for the SABE Study, which was reviewed by experts of Latin America and the Caribbean. The social network was evaluated using the variables: social support received; social support offered; number of members in the social network. The covariates included were age, gender, living arrangements, marital status, income, education, comorbidity, depressive symptoms, cognition and functional difficulties. Death as an outcome was evaluated after four years of follow-up. RESULTS: From a total of 1413 older adults at baseline, 268 died in a mean follow-up period of 3,9 years (SE=0,03). In the model adjusted offering social support and having networks composed of 9 or more members reduced the risk of death in the older adults. CONCLUSIONS: This study suggest that older adult who are offered support can benefit from mutual exchanges since reciprocity in relationships improves psychological well-being and is indicative of the quality of relationships. Thus, the older adults are part of a group of people whose role is not only to receive, but also to provide help to others, and the support offered seems to be as important as that received.

The objective of this study was to identify the relationship between social support and the functional capacity of elderly persons with cognitive alterations. It is a descriptive, cross-sectional and quantitative study. The subjects were 101 elderly persons registered in Family Health Centers whose performance in the Mini-Exam for Mental Status was below a certain specified level in a previous study. The Medical Outcomes Study questionnaire, Katz Index and Pfeffer Questionnaire were applied. The dimensions of material, affective, emotional, informational and positive social interaction support resulted in an average final score of 74.32 points, indicating a better level of material and affective support in relation to the other dimensions of support. There was a statistically significant correlation between emotional support and the Katz Index. Knowledge about this relationship favors the development of a nursing care pathway for the elderly which is capable of maintaining their functional capacity and ensuring satisfactory social relations.

The objective of this study was to analyze the structure and role of social support networks for the elderly with cognitive alterations, who lived in a context of high or very high social vulnerability, and identify the associations between the characteristics of the networks and functional capacity. The participants were 38 aged individuals living in a context of high or very high social vulnerability whose score on the Mini-Mental State Examination was below the cut-off point. All ethical considerations were observed. The following were administered: Mini-Mental State Examination, Convoy of Social Support, Katz Index, and Pfeffer Questionnaire. The results show that the elderly participants have a large social network, with most members in their inner circle, but only a few of the members play functional roles. A correlation was observed between the gender variable and the number of social network members. No significant correlation was observed between network characteristics and the functional capacity of the elderly.
