AbstractAlthough the obesity paradox is an important modifiable factor in cardiovascular diseases, little research has been conducted to determine how it affects post-stroke cognitive function. We aimed to investigate the association between body mass index (BMI) and domain-specific cognitive outcomes, focusing on the subdivision of each frontal domain function in post-ischemic stroke survivors. A total of 335 ischemic stroke patients were included in the study after completion of the Korean-Mini Mental Status Examination (K-MMSE) and the vascular cognitive impairment harmonization standards neuropsychological protocol at 3 months after stroke. Frontal lobe functions were analyzed using semantic/phonemic fluency, processing speed, and mental set shifting. Our study participants were categorized into four groups according to BMI quartiles. The z-scores of K-MMSE at 3 months differed significantly between the groups after adjustment for initial stroke severity (p = 0.014). Global cognitive function in stroke survivors in the Q1 (the lowest quartile) BMI group was significantly lower than those in Q2 and Q4 (the highest quartile) BMI groups (K-MMSE z-scores, Q1: − 2.10 ± 3.40 vs. Q2: 0.71 ± 1.95 and Q4: − 1.21 ± 1.65). Controlled oral word association test findings indicated that phonemic and semantic word fluency was lower in Q4 BMI group participants than in Q2 BMI group participants (p = 0.016 and p = 0.023 respectively). BMI might differentially affect cognitive domains after ischemic stroke. Although being underweight may negatively affect global cognition post-stroke, obesity could induce frontal lobe dysfunctions, specifically phonemic and semantic word fluency.

Background: There is evidence that physical activity (PA), sitting time, and obesity may impact cognition, but few studies have examined this in young women. Methods: Healthy women (18–35 y), without conditions that impair cognition, were recruited for this cross-sectional study. Participants completed anthropometric and validated computerized cognitive assessments (IntegNeuro™). Performance on 5 cognitive domains (impulsivity, attention, information processing, memory, and executive function) was reported as z scores. Sitting hours and weekly PA calculated from time in low-, moderate-, and high-intensity activity were obtained via the International Physical Activity Questionnaire. Analysis of variance/analysis of covariance, chi-square, and linear regression were used. Results: 299 (25.9 [5.1] y) women (low PA = 19%; moderate PA = 40%; high PA = 41%) participated. High PA women had lower body mass index (high PA = 26.1 [6.5]; moderate PA = 30.0 [8.7]; low PA = 31.0 [11.1] kg/m2; P < .001) and less sitting time (high PA = 6.6 [3.1]; moderate PA = 7.7 [2.8]; low PA = 9.3 [3.6] hr/weekday; P < .0001). Cognitive function was within normal ranges and did not differ between any PA groups (P = .42). Adjusting for body mass index, C-reactive protein, or sitting hours did not alter results. Weak correlations were found between time in high-intensity activity and impulsivity (b = 0.12, r2 = .015; P = .04), and between sitting hours and information processing efficiency (b = −0.18, r2 = .03; P = .002). Valuesare presented as mean (SD). Conclusions: Cognitive function was within the normal range, regardless of PA or sitting time.

Background: Present rise in the incidence of obesity has led to several opposing reports regarding the association between obesity and stroke outcomes. The objective of this study was to investigate a proposed paradoxical relationship between body mass index (BMI) and functional status in ischemic stroke patients at time of hospital discharge. Methods: Saint Francis Hospital Comprehensive Stroke Center patient databases were utilized in identifying 948 patients eligible for retrospective chart review over a period of 15 months. Subjects were divided into 4 groups according to BMI: underweight (BMI < 18.5 kg/m 2 ), normal weight (BMI 18.5-24.9 kg/m 2 ), overweight (BMI 25.0-29.9 kg/m 2 ), and obese (BMI ≥ 30.0 kg/m 2 ). Covariates, such as age, gender, prior to event modified Rankin scale (mRS), stroke recurrence, and smoking, were considered. Functional status and disability of stroke patients was scored via mRS at hospital discharge. Ordered logistic regression, Pearson’s chi-squared test, and Pearson’s r correlation were used for analysis to assess the association of BMI and functional status in ischemic strokes. Results: Of 948 eligible subjects, 49.9% were female and mean (SD) age was 69.4 (14.5) years. According to BMI, 22 (2.3%) were underweight, 247 (26.1%) normal weight, 319 (33.7%) overweight, and 360 (37.9%) obese. After adjusting for covariates, ischemic stroke patients with an increased BMI (OR, 0.98; 95% CI, 0.96-0.99) were not associated with increased disability risk upon discharge. Obese (16.2%) and overweight (14.1%) patients discharged with a mRS of 0 (back to baseline) or 1 more frequently compared to normal weight (6.1%) and underweight (0.21%) patients ( P <0.001). Furthermore, an inverse association between BMI status and disability was significantly evident ( r = -0.17, P < 0.001). Conclusion: Obese and overweight stroke patients discharge with a lower risk of disability than normal weight and underweight patients, supporting the existence of the “obesity paradox” in stroke. An inverse association between obesity status and functional outcome was identified and remained significant regardless of covariates.

Abstract Primary Subject area Public Health and Preventive Medicine Background The WHO provides body mass index (BMI) curves for infants 0 to &lt; 2 years old, but how these compare to the recommended method (weight-for-length [WFL]) in predicting later adiposity and cardiometabolic measures is uncertain. Objectives Our project aimed to: 1) confirm that WFL and BMI in infancy are associated with adiposity and cardiometabolic measures at 8-10 years old; and 2) compare the predictive ability of the two methods. We hypothesized that both methods would perform similarly. Design/Methods WFL and BMI Z-scores (zWFL and zBMI) at 6, 12, and 18 months of age were computed using data extracted from health booklets, used among participants in a prospective cohort study investigating the natural history of obesity and cardiovascular risk in youth (n = 464). Outcome measures at 8-10 years included adiposity, lipid profile, blood pressure, and insulin dynamics. The relationships between zWFL, zBMI, and each outcome were estimated using multivariable linear regression models. Outcome prediction at 8-10 years was compared between the two methods, using eta-squared and Lin’s concordance correlation. Results zWFL and zBMI were associated with all measures of adiposity at 8-10 years. Associations with other cardiometabolic measures were less consistent. For both zWFL and zBMI across infancy, eta-squared were highly similar and the Lin’s coefficients were markedly high (&gt; 0.991) for all outcomes. Conclusion zBMI measured in infants appeared to be equivalent to zWFL for predicting adiposity and cardiometabolic measures in childhood. This lends support to the sole use of zBMI for growth monitoring and screening of overweight and obesity from birth to 18 years.

Lifestyle Pattern

Many lifestyle factors have been linked to cognitive function but little is known about their combined effect. An overall lifestyle pattern for people living in the Mediterranean basin has been proposed, including diet, but also physical activity, sleep and daily living activities with social/intellectual aspects. We aimed to examine the associations between a combination of these lifestyle factors and detailed cognitive performance. A total of 1716 participants from the Hellenic Longitudinal Investigation of Ageing and Diet (HELIAD), a population-based study of participants ≥65 years, were included in this analysis. Lifestyle factors were evaluated using standard, validated questionnaires and a Total Lifestyle Index (TLI) was constructed. Cognitive outcomes included mild cognitive impairment (MCI) diagnosis, a composite z-score (either continuous or with a threshold at the 25th percentile) and z-scores for five cognitive domains. A higher TLI was associated with 65% reduced odds for MCI in the non-demented individuals and 43% reduced odds for low global cognition when MCI participants were excluded, a risk reduction equivalent to 9 and 2.7 fewer years of ageing, respectively. Each lifestyle factor was differentially associated with domain-specific cognitive performance. Our results suggest that a TLI, more so than single lifestyle parameters, may be related to cognitive performance.

The aim of work is to exposure how disbalance of male sex hormones in the period of the age-specific reorganization affects development of atherosclerosis and vascular disorders by the example of ischemic stroke, establishment of correlation between hormonal dysfunction by the example testosterone and lipid metabolism according to the somatic type in the critical period of ischemic stroke. The pilot analysis of level of sex hormones by the example testosterone, lipids and body mass index confirms that there is correlation between these indices. Rising of body mass index is accompanied by reduction of sex hormone concentration, but for all that levels of cholesterol and atherogenic fraction are increased.

AbstractBackgroundReferences from the Global Lung Function Initiative (GLI) are widely used to interpret children’s spirometry results. We assessed fit for healthy schoolchildren.MethodsLuftiBus in the school (LUIS) is a population-based cross-sectional study done from 2013-2016 in the canton of Zurich, Switzerland. Parents and children aged 6-17 years answered questionnaires about respiratory symptoms and lifestyle. Children underwent spirometry in a mobile lung function lab. We calculated GLI-based z-scores for FEV1, FVC, FEV1/FVC, and FEF25-75 for healthy White participants. We defined appropriate fit to GLI references by mean values ±0.5 z-scores. We assessed if fit varied by age, body mass index, height, and sex using linear regression models.ResultsWe analysed data from 2036 children with valid FEV1 measurements of which 1762 also had valid FVC measurements. The median age was 12.2 years. Fit was appropriate for children aged 6-11 years for all indices. In adolescents aged 12-17 years, fit was appropriate for FEV1/FVC (mean: -0.09; SD: 1.02) z-scores, but not for FEV1 (mean: -0.62; SD: 0.98), FVC (mean: -0.60; SD: 0.98), and FEF25-75 (mean: -0.54; SD: 1.02). FEV1, FVC, and FEF25-75 z-scores fitted better in children considered overweight (means: -0.25, -0.13, -0.38) than normal weight (means: -0.55, -0.50, -0.55; p-trend: <0.001, 0.014, <0.001). FEV1, FVC, and FEF25-75 z-scores depended on both age and height (p interaction: 0.034, 0.019, <0.01).ConclusionGLI-based FEV1, FVC, and FEF25-75 z-scores do not fit White Swiss adolescents well. This should be considered when using reference equations for clinical decision making, research and international comparison.Take home messageOur study suggests GLI-based FEV1, FVC, and FEF25-75 z-scores over detect abnormal lung function in Swiss adolescents, and more so among slimmer adolescents, which has important implications for clinical care, research, and international comparisons.
