ABSTRACT

Cognitive impairment (CI) has a multifactorial etiology. Some studies have suggested that inflammatory, oxidative and antioxidant status and physical activity are associated with CI. However, the evidence on this subject is still controversial. The goal of this study was to verify the association of caloric expenditure by physical activity, oxidative, antioxidant power and inflammatory biomarkers with CI in older adults. We performed a cross-sectional study of 424 elderly (224 with normal cognitive function and 200 with CI) patients from the Family Health Strategy in Porto Alegre, Rio Grande do Sul, Brazil. The variables investigated were sociodemographic, biochemical, inflammatory (hs-CRP, IL-6), oxidative (TBARS, AOPP), antioxidant power (FRAP) biomarkers, energy expenditure, and cognitive function. The instruments used were the Minnesota Leisure Time Physical Activity Questionnaire + Compendium of Physical Activities, classification of energy costs of human physical activities (for physical activity evaluation and measurement of energy expenditure in METs), and a battery of neuropsychiatric instruments (for cognitive ability assessment). We found statistically significant differences only with respect to HDL-c and age (higher averages in the CI group; P<0.05). We observed no differences between the groups with respect to biochemical, inflammatory, oxidative and FRAP biomarkers or caloric expenditure. Logistic regression showed that HDL-c (OR=1.02 [IC=95%; 1.01-1.04]; P=0.011), and age (OR=1.05 [IC=95%; 1.02-1.08]; P=0.004) are independent factors associated with CI. Our results suggest that the biochemical (except HDL-c), inflammatory, oxidative, and FRAP biomarkers investigated and caloric expenditure are not associated with CI in the elderly assisted at primary care.

ABSTRACT

OBJECTIVES: To assess overactive bladder (OAB) prevalence, associated factors and implications in a young population. METHODS: An independent population-based study was carried out. A self-applicative questionnaire covering urinary symptoms, coping strategies, quality of life and treatment seeking behavior was developed. RESULTS: A total of 848 subjects between 15 and 55 years completed the questionnaire. The overall prevalence of OAB was 18.9%. Women were significantly more affected than men (p = 0.001). All age groups were equally affected (p = 0.152). Subjects with OAB reported significant impairment on household chores (p = 0.009), physical activities (p = 0.016), sleep (p < 0.001), work (p < 0.001), social life (p < 0.001) and sexual life (p < 0.001). In addition, OAB individuals present higher prevalence of depression (p = 0.036), anxiety (p < 0.001), shame (p < 0.001) and tiredness (p < 0.001) OAB was independently associated to sexual life impairment (OR = 3.36, 95% CI=1.20-9.39). Only 27.5% of OAB subjects sought for medical counseling. CONCLUSIONS: OAB is a highly prevalent condition, even in such a young population. It affects both genders, yet it is more frequently observed in women. OAB is an important health condition, with serious impact on quality of life and sexual function. A large percentual of individuals remain unrecognized, under treated and consequently suffer for long periods of time.
