This study aims to investigate the association between physical fitness and markers of cognitive function in adults aged 40 and above in Qatar.
A cross-sectional study.
The Qatar Biobank, data of 1000 adults aged 40 and above.
A population of 1000 adults aged 40 years and older was included. Available data comprised measures of physical fitness including cardiorespiratory fitness, muscular strength, body composition and physical fitness capacity, as well as cognitive function assessed through tests of short-term visual memory and psychomotor coordination.
This paper investigated the physical fitness effect on cognitive functioning through short-term visual memory and psychomotor coordination testing. Logistic regression was used to measure the association between physical fitness and cognitive functioning tests.
Our study showed that lower physical fitness capacity was significantly associated with lower psychomotor coordination in females (OR=1.57, p=0.040) and showed no significant association in males (OR=1.65, p=0.062). For short-term visual memory, the association was significant in females (OR=1.68, p=0.042) unlike in males (OR=1.58, p=0.062). Males with greater muscle strength were about half as likely to have lower psychomotor coordination (OR=0.48, p=0.04). In females, a higher body fat percentage was associated with poorer cognitive function, with each 1% increase in body fat being linked to 6% higher odds of low short-term visual memory (p=0.02) and low psychomotor coordination (p=0.006). Cardiorespiratory fitness showed no statistically significant association with short-term visual memory and psychomotor coordination level in either sex.
Our findings suggest that overall physical fitness capacity is associated with better cognitive function in Qatari adults. The relationship between specific fitness measures and cognitive function varied by sex, with muscle strength having a stronger effect for males and body composition for females. These results highlight the potential importance of maintaining physical fitness for cognitive health in adulthood.
Maternal and child mortality has markedly decreased worldwide over the past few decades. Despite this success, the decline remains unequal across countries and is overall insufficient to meet the Sustainable Development Goals. South Asia and sub-Saharan Africa bear most of the burden of maternal and child morbidity and mortality. Major gaps persist in our understanding of the causes, timing, diagnostic thresholds and risk factors for adverse outcomes in these regions. Addressing these gaps requires new ways to prevent and treat disease, from novel diagnostics to precision public health strategies, all of which rely on high-quality clinical data from diverse populations. The Pregnancy Risk, Infant Surveillance, and Measurement Alliance (PRISMA) Maternal and Newborn Health Study aims to estimate population-level prevalence of morbidities and mortality and to assess biological, clinical and sociodemographic risk among mother–infant pairs in India, Pakistan, Kenya, Ghana and Zambia.
This study is a prospective, open cohort study with a planned recruitment of about 6000 women annually across six research sites in five countries. Participants are pregnant women enrolled less than 20 weeks gestation, as determined by ultrasound, identified through active house-to-house and facility-based surveillance. Robust clinical data will be collected at 12 scheduled study visits during antenatal care, labour and delivery, and through 1 year postpartum. A total of 34 outcomes will be captured. The primary analysis will estimate the burden of adverse outcomes and examine associated risk factors to inform future intervention strategies. Data will also be used to develop normative values for pregnant and postpartum women, as well as predictive models to assess pregnancy risk.
PRISMA received institutional and national ethical approvals. Findings will be published in peer-reviewed open-access journals and disseminated at national and international forums to inform clinical guidelines and public health practice.
Non-adherence to tuberculosis (TB) treatment remains a major challenge in high-burden regions. However, few studies have qualitatively examined the sociocultural and emotional barriers to adherence, particularly among Afghan refugees in Pakistan. This study explores the patient-related, sociocultural and treatment-related barriers to treatment adherence among patients with TB of Pakistani and Afghan origin living in Pakistan.
We conducted an exploratory qualitative study consisting of semistructured focus group discussions (FGDs) and in-depth interviews (IDIs) with purposively selected multisectoral stakeholders. The data were analysed thematically using a combination of inductive and deductive approaches.
We employed a qualitative study design in the TB DOTS (Directly Observed Treatment Short course) centres in the Haripur and Peshawar districts of Khyber Pakhtunkhwa province, Pakistan.
We conducted IDIs (n=29) and FGDs (n=11) with three categories of participants: TB healthcare providers, patients with TB and their carers.
We identified several contributors to lower treatment adherence. These included patient-related barriers (eg, lack of awareness about TB and its treatment), sociocultural barriers (eg, stigma, refugee status of Afghan patients, gender roles and reliance on traditional and spiritual healing) and treatment-related barriers (eg, demanding treatment regimen and TB-induced depression).
Several personal, sociocultural and treatment-related barriers contribute to lower treatment adherence in patients with TB. A significant contributing factor to treatment non-adherence in patients is the high prevalence of anxiety and depression related to TB and its treatment, for which there is no treatment or counselling available at the DOTS level in Pakistan, warranting the need for mental health interventions that could improve adherence and treatment outcomes for both TB and depression.
