ABSTRACT: There is evidence to support the favorable impact of physical activity (PA) on brain volume. However, the empirical evidence exploring the relationship between physical and sedentary behavior remains mixed. We aimed to explore the relationship between PA and sedentary behavior and brain volume. The study sample (n = 150, mean age = 39.7 years) included patients interviewed with the International Physical Activity Questionnaire (IPAQ) who underwent an MRI brain scan. From the images obtained, we measured total intracranial, gray matter, and white matter volume along with the hippocampus, amygdala, parahippocampal gyrus, and posterior cingulate cortex (PCC). Multivariable linear regression analysis was done. Left hippocampus and overall PA were positively and significantly associated (β = 0.71, p = 0.021) whereas time spent on vigorous physical activity showed a negative association (β = -0.328, p = 0.049) with left hippocampal volume. We found a positive association between total PA and the left hippocampus, whereas vigorous PA showed a negative association with the left hippocampus.

Project description:IntroductionAnemia is a significant public health concern, primarily affecting young children, pregnant and postpartum women, and menstruating adolescent girls and women. This study aimed to evaluate the prevalence of anemia and associated factors in women of reproductive age visiting a tertiary care hospital in Karachi, Pakistan.ObjectiveThe primary objective was to determine the prevalence of anemia in women of reproductive age, while the secondary objective was to investigate potential causes of anemia within this demographic group.DesignA prospective cross-sectional approach was employed, adhering to Strengthening the Reporting of Observational Studies in Epidemiology guidelines. A questionnaire-based method was used to assess anemia, and data were collected from women aged 14 to 40 years.MethodThe study was conducted at the Jinnah Postgraduate Medical Center from January to May 2023. The study was approved by the Institutional Review Board of Jinnah Sindh Medical University (Institutional Review Board reference number JSMU/IRB/2023/699). A sample of 397 women was included, and various demographic and lifestyle factors were assessed.ResultsIn this study of 397 participants, 71.5% were found to have anemia, primarily microcytic anemia (48.2%). Anemia prevalence was highest among the 14-18 years age group (80.7%) and those from lower socioeconomic backgrounds (73.6%). Factors such as frequent tea consumption, irregular mealtimes, and pica consumption were associated with higher anemia rates. Pregnant women and those with more children were at a heightened risk of anemia.ConclusionThe study reveals a notable prevalence of anemia among women of reproductive age with a surprising emphasis on younger individuals and lower socioeconomic groups. Dietary habits, lifestyle choices, and pregnancy status play significant roles in anemia development. Targeted interventions are essential, particularly for younger women, those from disadvantaged backgrounds, and pregnant individuals, to combat anemia effectively in this region.

Project description:BackgroundDespite efforts to contain the spread of COVID-19, Addis Ababa, the country's COVID-19 epicenter, is experiencing a sharp increase in the number of cases and death rate. While poor public adherence to COVID-19 precautionary practices is evident, factors associated with it are not well studied. We aimed to assess the level of practice of COVID-19 precaution and associated factors.MethodsThis was a hospital-based cross-sectional study conducted from February 1st to 15th, 2021 at Saint Paul's Hospital Millennium Medical College, a tertiary teaching hospital in Addis Ababa, Ethiopia. We used a structured questionnaire to conduct a face-to-face exit interview with clients visiting the hospital. Systematic random sampling was employed to recruit study participants. Binary and multivariable logistic regressions were implemented to examine factors associated with precautionary practices. Statistical significance was declared at p-value <0.05. The Crude odds ratio (COR) and Adjusted odds ratio (AOR) were reported with a 95% confidence interval.ResultsWe analyzed data obtained from 262 participants. The mean age of participants was 36 (SD+12) years. The majority (207, 79%) of the study participants had a favorable attitude towards prevention and control measures of COVID-19. A little over half (116, 55.7%) of the respondents had a satisfactory level of practice of COVID-19 precautions. Living in an area with strict enforcement of COVID-19 precautionary measures [AOR: 2.25, 95% CI (1.22-4.15)], and having a favorable attitude of COVID-19 prevention [AOR: 4.88, 95% CI (2.08-11.68)] were significantly associated with satisfactory COVID-19 precautionary practices.ConclusionsThe level of practice of COVID-19 precaution was unsatisfactory. Favorable attitude and stricter enforcement of COVID-19 preventive measures might have contributed more to adherence to precautionary practices. The findings highlight the need for a public health education strategy targeted at improving attitudes of the community on COVID-19 focusing on the effectiveness of preventive measures.

Project description:BackgroundHospital-acquired disability (HAD) is common and often related to low physical activity while in the hospital.ObjectiveTo examine whether wearable hospital activity trackers can be used to predict HAD.DesignA prospective observational study between January 2016 and March 2017.SettingAn academic medical center.ParticipantsCommunity-dwelling older adults, aged 60 years or older, enrolled within 24 hours of admission to general medicine (n = 46).Main measuresPrimary outcome was HAD, defined as having one or more new activity of daily living deficits, decline of four or greater on the Late-Life Function and Disability Instrument (calculated between baseline and discharge), or discharge to a skilled nursing facility. Hospital activity (mean active time, mean sedentary time, and mean step counts per day) was measured using ankle-mounted accelerometers. The association of the literature-based threshold of 900 steps/day with HAD was also evaluated.ResultsMean age was 73.2 years (SD = 9.5 years), 48% were male, and 76% were white. Median length of stay was 4 days (interquartile range [IQR] = 2.0-6.0 days); 61% (n = 28) reported being able to walk without assistance of another person or walking aid at baseline. Median daily activity time and step counts were 1.1 h/d (IQR = 0.7-1.7 h/d) and 1455.7 steps/day (IQR = 908.5-2643 steps/day), respectively. Those with HAD (41%; n = 19) had lower activity time (0.8 vs 1.4 h/d; P = .04) and fewer step counts (1186 vs 1808 steps/day; P = .04), but no difference in sedentary time, compared to those without HAD. The 900 steps/day threshold had poor sensitivity (40%) and high specificity (85%) for detecting HAD.ConclusionsLow hospital physical activity, as measured by wearable accelerometers, is associated with HAD. Clinicians can utilize wearable technology data to refer patients to physical/occupational therapy services or other mobility interventions, like walking programs. J Am Geriatr Soc 68:261-265, 2020.
