Purpose: The aim of the present study was to identify factors associated with the occurrence of falls among elderly adults in a population-based study (ISACamp 2008). Methods: A population-based cross-sectional study was carried out with two-stage cluster sampling. The sample was composed of 1,520 elderly adults living in the urban area of the city of Campinas, São Paulo, Brazil. The occurrence of falls was analyzed based on reports of the main accident occurred in the previous 12 months. Data on socioeconomic/demographic factors and adverse health conditions were tested for possible associations with the outcome. Prevalence ratios (PR) were estimated and adjusted for gender and age using the Poisson multiple regression analysis. Results: Falls were more frequent, after adjustment for gender and age, among female elderly participants (PR = 2.39; 95% confidence interval (95%CI) 1.47 - 3.87), elderly adults (80 years old and older) (PR = 2.50; 95%CI 1.61 - 3.88), widowed (PR = 1.74; 95%CI 1.04 - 2.89) and among elderly adults who had rheumatism/arthritis/arthrosis (PR = 1.58; 95%CI 1.00 - 2.48), osteoporosis (PR = 1.71; 95%CI 1.18 - 2.49), asthma/bronchitis/emphysema (PR = 1,73; 95%CI 1.09 - 2.74), headache (PR = 1.59; 95%CI 1.07 - 2.38), mental common disorder (PR = 1.72; 95%CI 1.12 - 2.64), dizziness (PR = 2.82; 95%CI 1.98 - 4.02), insomnia (PR = 1.75; 95%CI 1.16 - 2.65), use of multiple medications (five or more) (PR = 2.50; 95%CI 1.12 - 5.56) and use of cane/walker (PR = 2.16; 95%CI 1.19 - 3,93). Conclusion: The present study shows segments of the elderly population who are more prone to falls through the identification of factors associated with this outcome. The findings can contribute to the planning of public health policies and programs addressed to the prevention of falls.

BackgroundOlder people are particularly exposed to stressful events, known to activate the hypothalamus-pituitary-adrenal axis. Many studies highlighted the possible deleterious effects of elevated cortisol on cognition, assuming a likely role of stressful events. Yet, very few studies actually examined these assumed links between life events, cortisol and cognition.ObjectiveTo examine associations between salivary cortisol, cognition and life events in a population of non-demented old individuals.MethodsA cross-sectional analysis was conducted using data from Colaus/PsyColaus, a longitudinal population-based study involving 6733 Lausanne residents. Salivary cortisol samples (upon waking, 30 minutes after waking, at 11 am and at 8 pm) were obtained from 799 non-demented participants aged at least 60.Life events, activities of daily life along with depressive symptoms were assessed using a standardized questionnaire. A comprehensive neuropsychological test battery was used to determine the Clinical Dementia Rating (CDR).For multiple comparisons, P values were adjusted (P′) according to Holm-Bonferroni's method.ResultsCortisol at 11 am and cortisol area under the curve (AUC) were positively correlated with CDR sum of boxes (CDRSOB) scores (P′ = 0.035; Rho = 0.097 and P′ = 0.024; Rho = 0.110, respectively). The association between cortisol AUC and CDRSOB remained significant after controlling for age, sex, body mass index, education, smoking and depression (P = 0.001; β = 0.001; R2 change = 0.016).The number and the total impact of life events were associated neither with cortisol nor with CDRSOB.ConclusionsElevated cortisol was associated with poorer cognitive functioning yet independently of life events. This suggests that the increased cortisol associated with poorer cognition might be not a mere reflection of stressful events but rather explained by other factors, yet to be elucidated.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Late Night Salivary Cortisol

AbstractBackground:Late-night salivary cortisol (LNSC) is one of the most reliable tests to screen for endogenous Cushing syndrome. This test is simple, inexpensive and noninvasive and has high sensitivity and specificity. The aim of our study was to analyze the putative influence of age, gender and body mass index (BMI) on LNSC levels in a healthy population.Methods:Cross-sectional study conducted in healthy adults. Midnight saliva samples were collected at home. Participants refrained from teeth brushing, eating or drinking for 2 h prior to collection. Salivary cortisol measured by electrochemiluminescence immunoassay (ECLIA). The study was approved by the Ethics Committee of the hospital (number 140073).Results:We evaluated 122 nonsmoking healthy volunteers. Mean age was 35±14 years (range, 18–74 years); 63% were women. Mean BMI was 24±3 kg/mConclusions:The maximum reference value (P97.5) of LNSC was set at 8.3 nmol/L (0.3 μg/dL) using ECLIA. Advanced age was associated with higher LNSC levels, with no evident influence of gender or BMI.

Abstract Object: to examine the characteristics to the last fall of Brazilian elderly persons who experienced falls in 2008 and 2009, and to identify if there is a relationship with sociodemographic characteristics, physical health, comorbidities, clinical conditions and the circumstances of the falls. Methods: a cross-sectional, population based study was carried out with participants aged 65 and older from Barueri in the state of São Paulo and Cuiabá in the state of Mato Grosso, Brazil. Households were enrolled within each census region according to population density and the number of elderly persons living in each region. A multidimensional questionnaire composed of sociodemographic factors and data regarding falls was used. Associations were analyzed using contingency tables, and Fisher's Exact or Pearson's Chi-square test was used. Results: 774 elderly people were included in the study, 299 of whom reported falling in the previous year. Of these, 176 (58.9%) had fallen once and 123 (41.1%) reported having fallen twice or more. Among fallers the mean age was 72.53 (±6.12) years and 214 (71.6%) were female. About 107 (35.8%) of the elderly reported having fallen forwards, 79 (26.4%) fell to the side and 42(14%) fell backwards. Regarding the circumstances of the falls, 107 (35.8%) reported having lost their balance, 79 (26.4%) said they had stumbled and 42 (14%) said they had slipped. There was an association between the mechanism and circumstances of the falls and having fallen once or twice or more. There was an association between the circumstances of falls and the number of medications taken. Conclusion: The characteristics of falls were different among elderly persons who had fallen once or twice or more, which may guide health professionals, the elderly and their families in relation to specific fall prevention strategies.

Abstract Background The addition of low-calorie sweeteners (LCS) has been increasingly used by industry but their metabolic effects are controversial. Objectives: to estimate the consumption of foods and beverages with LCS among adolescents, adults and the elderly and to verify which food categories most contribute to this consumption. Methods Cross-sectional study. We used data from the Campinas Health Survey (ISACamp 2014-15) and the Food Consumption and Nutritional Status Survey (ISACamp-Nutri 2015-16) of 2570 individuals from 10 years old. We estimated the prevalence of LCS consumption and described the food categories that most contributed to this consumption. Using regression analysis, we verified which population groups had the highest consumption of products with LCS. Results More than 40% of adolescents, adults and the elderly consumed at least one product with LCS, mainly coming from sweetened beverages, tabletop sweeteners, and yogurt and other dairy beverages. The consumption of LCS was evenly found across adolescents and elderly from all socioeconomic strata, and whether elderly participants presented overweight and/or diabetes. Among adults, greater prevalence of foods and beverages with LCS consumption was found in those with higher education but did not vary by the presence of overweight and/or diabetes. Conclusions We found similar consumption of foods and beverages with LCS in most socioeconomic strata, and in participants with and without overweight or diabetes. Key messages The results can contribute to the development of public policies on clearer information of LCS addition in food labels.

OBJECTIVE: To determine the prevalence and factors associated with urinary incontinence in the elderly population of Florianópolis, in the State of Santa Catarina, Brazil. METHODS: We used data from EpiFloripa Idoso 2009/2010 survey, a cross-sectional population-based study including 1,705 elderly of both the sexes. Poisson's regression (crude and adjusted analysis) was applied to verify the association between the urinary incontinence outcome and exploratory variables (sociodemographic, lifestyle, and health conditions). RESULTS: Among the elderly, 29.4% reported urinary incontinence; 36.3% were women and 17.0% men. The factors associated with greater prevalence of urinary incontinence were being female, aged more than 70 years old, having 0 to 4 schooling years, being insufficiently active, having bronchitis or asthma, stroke or cerebral ischemia, presenting mild or moderate/severe dependence, and polypharmacy. CONCLUSION: The prevalence of urinary incontinence was high among the investigated elderly. Sociodemographic variables and those related to lifestyle and health conditions were associated with higher prevalence of urinary incontinence. Knowledge of the factors associated with urinary incontinence in aged individuals can guide actions to reduce and prevent this important issue, which affects the elderly.

Objective: To assess the self-reported vaccination in older adults within the city of Bogotá and its distribution by sociodemographic factors. Methods: Data analyzed was taken from the SABE-Bogotá study. A total of 2000 persons aged 60 years and older were selected for this cross-sectional population-based study. Bivariate and multivariate analyses were performed testing the association between vaccination and sociodemographic factors. Results: A total of 73.0% of respondents received the influenza vaccine, 57.8% received pneumococcal vaccine and 47.6% received tetanus vaccine. In multivariate analyses, individuals aged between 65-74 years had higher odds of receiving influenza, pneumococcus and tetanus vaccination, compared to those between 60-64 years. Older adults with higher socioeconomic status (SES) had lower odds of having influenza and pneumococcus vaccines, compared to those with lower SES (OR= 0.16 95% confidence intervals= CI 0.08-0.30; OR 0.20 95% CI 0.10-0.38, respectively). Individuals covered by health insurance (contributive or subsidized) had higher odds (between 3 and 5 times higher) of having influenza, pneumococcus and tetanus vaccination, compared to those with no insurance. Conclusion: Older adults between 65 and 74 years, those with health care coverage and people with low SES are groups that have increased odds for self-reported vaccination. Further studies should identify factors that increase vaccination coverage in these groups and implement interventions targeted at improving coverage among older adults in general.
