A cross-sectional survey was done to investigate the pathways the physical activity acts in improving physical fitness and functional outcomes of older adults (60 years and above) using 880 community-dwelling older adults in Sri Lanka. Structural Equation Modeling (SEM) was used. The final SEM model included five latent factors and 14 co-variances. Goodness of Fit Index (GFI), Comparative fit index (CFI) and Root Mean Square Error of Approximation (RMSEA) values of the model were 0.95, 0.93, 0.91, and 0.05 respectively, indicating a good model fit. Strength enhances balance (β = .52, p < .01) and reduces the time required to complete physical functions (β = −.65, p < .01). Since strength declines with advancing age, muscle-strengthening activity programs should be promoted to enhance balance and functional performances in older adults in advanced ages. Strength test (hand grip and leg strength) can be used as a screening test to predict potential risk of falls and functional disabilities in older adults.

The elderly population in Sri Lanka is growing rapidly. Elders are traditionally cared for in the homes of their adult children, but the shifting socio-economic environment in Sri Lanka challenges this arrangement. This paper describes the dynamics of elder–care-giver relationships in Southern Sri Lanka. Data included four focus group discussions and five in-depth interviews with elderly, and ten in-depth interviews with adult children of the elderly. Discussion guide topics included care-giving arrangements, and roles/responsibilities of elders and care-givers. Using a grounded theory approach, a comprehensive analytic memo was developed and discussed to explore emerging themes on the care-giver dynamic. Both elders and care-givers felt that elders should be taken care of in the home by their children. They pointed to a sense of duty and role modelling of parental care-giving that is passed down through generations. Even as elders desired support from their children, they feared losing their independence, and saw financial autonomy as important for maintaining relationship balance. Care-giving challenges included: households where both the adult child and his/her spouse worked outside the home; households where elders had a disproportionate amount of household work; economically stressed households; and lack of direct communication between elders and care-givers regarding conflicts. Results point to strong values around caring for elderly in the home, but identify challenges to this arrangement in the future.

Sri Lanka lacks robust estimates of hypertension (HTN) prevalence owing to few national studies, hindering optimization of control strategies. Evidence on how the revised 2017 American College of Cardiology/American Heart Association (ACC/AHA) HTN definition affects prevalence in low- and middle-income countries (LMICs) is also limited. To make robust estimates of HTN prevalence in the Sri Lankan adult population, and to assess impact of the ACC/AHA 2017 definitions. Data were sourced from the 2018–2019 first wave of the Sri Lanka Health and Ageing Study (SLHAS), a nationally representative longitudinal study of the noninstitutionalized adult population. After excluding those with missing data and aged <18 years, 6,342 participants (95.1%) were included in the analysis. HTN was defined using either the traditional threshold of systolic BP (SBP) ≥140 mmHg or a diastolic BP (DBP) ≥90 mmHg, or the ACC/AHA 2017 threshold of SBP ≥130 mmHg or DBP ≥80 mmHg, or if taking antihypertensive medication. Estimated prevalence of HTN in all Sri Lankan adults was 28.2% using the traditional definition, and it doubled to 51.3% when applying the ACC/AHA 2017 definition. Of those classified as hypertensive according to the older and ACC/AHA 2017 definitions, 53.4% and 31.2%, respectively, were previously diagnosed. Of the 23.2% of adults reclassified as hypertensive by the ACC/AHA 2017 definition, 16.6% had a history of CVD or diabetes. Increased prevalence was associated with urban residence, socioeconomic status, obesity, and Muslim ethnicity. Prevalence increased with age, but the increase was steeper in women from their 30s. Nearly one in three adult Sri Lankans are hypertensive, requiring antihypertensive treatment. Applying the ACC/AHA 2017 definitions almost doubles numbers, but many of those reclassified would require treatment under recent WHO guidelines. Study findings also suggest that design effects in HTN surveys may be higher than usually assumed.

Background: The upsurge of COVID-19 has caused numerous psycho-social challenges for healthcare professionals because of its ability to spread rapidly in the community and high mortality rate. The seriousness of the disease has led many healthcare professionals plagued by stigma as well as discrimination. In this study, depressive symptomatology, levels of anxiety, and related psychosocial and occupational factors experienced by healthcare professionals in Sri Lanka during COVID -19 were investigated. Methods: A total of 512 healthcare professionals were surveyed using an online survey. The Generalized Anxiety Disorder 7-item scale, the Center for Epidemiologic Studies Depression Scale-Revised-10, and psychosocial and occupational factors predictive of depression and anxiety were included in the survey questionnaire. Logistic regression determined the factors associated with the presence of depressive symptoms and anxiety. Results: Results showed that elevated depressive symptoms and anxiety were experienced by 53.3% and 51.3%, respectively, of the participants. No differences in the prevalence of elevated depressive symptoms and anxiety were found between those who were exposed and non-exposed to COVID-19 confirmed or suspected patients. Having a fear of being infected with COVID-19 and spreading it among family members were associated with increased risk of depression. Among those exposed to COVID-19 confirmed or suspected patients, poor occupational safety (OR = 2.06, 95% CI 1.25–3.39), stigmatization (OR = 2.19, 95% CI 1.29–3.72), and heavy workload (OR = 2.45, 95% CI 1.53–3.92) were associated with increased risk of elevated depressive symptoms, whilst poor self-confidence (OR = 2.53, 95% CI 1.56–4.09) and heavy workload (OR = 1.94. 95% CI 1.22–3.12) were associated with increased risk of anxiety. Conclusions: Fear of being infected and distress caused by fear of spreading it among family members, stigmatization, poor self-confidence, poor occupational safety and heavy workload are vital risk factors that need to be considered in future psychological support services designed for the healthcare professionals in unprecedented outbreaks like COVID-19.

A questionnaire was administered to 1565 adults to identify the prevalence of smoking and to assess respondents' attitudes toward smoking. Of men 41% were yearly smokers, 27.8% were monthly smokers and 21% were daily smokers. The corresponding figures for women were 3.4%, 2% and 0.6% respectively. Higher prevalence rates were observed among less educated, middle-aged men who were from underprivileged families. About 23% of men and 0.9% of women were monthly alcohol users. Alcohol use seems to be positively associated with smoking. A considerable portion of both smokers and non-smokers expressed a favorable attitude towards smoking habits of adult males (40.1% of smokers and 12.8% of non-smokers) and towards the tobacco industry (25.1% of smokers and 13.1 of non-smokers). Since the majority of people in Sri Lanka are non-smokers, attitudinal support given by them in promoting smoking in the society needs to be addressed effectively in smoking control interventions.

The chronic disease burden in Saudi Arabia has created adverse health, social and economic consequences that require urgent attention from health and political authorities. Diabetes has become an epidemic in Saudi Arabia. Data on personal and structural factors associated with diabetes in the Hail region are scarce. Such data are imperative to develop effective strategies to control the epidemic in the region. A cross-sectional study of diabetes patients attending diabetes health care facilities in Hail was conducted using a sample of 392 patients. An interviewer-administered questionnaire was used. A slightly higher proportion of female participants (54.1%) were included in the sample. Most of the participants were from rural areas (73.9%), and 70.9% of the participants were from the middle-age (30–50 years) category. A close proximity to the diabetes clinic (OR = 1.98; 95% CI: 1.08–3.44), good transport facilities (OR = 1.67; 95% CI: 1.11–2.78) and feeling contented with supportive services (OR = 2.03; 95% CI: 1.12–4.04) were associated with patients’ satisfaction with the overall quality of the diabetes clinic services. The presence of good-quality health care professionals working in these treatment centers also seemed to contribute to patients’ satisfaction with the services they received. These structural factors associated with patients’ satisfaction with the services they received from diabetes clinics must be considered in diabetes control programs in the region. The minimization of structural barriers will eventually assist the national strategic plan, Vision 2030, which aims to improve the quality of life of the Saudi people by 2030.
