Physical inactivity as a risk factor to mortality by ischemic heart disease during economic and political crisis in Brazil

Low-level physical activity predictors among adults living with HIV in Ethiopia's southern region, focusing on work, transportation, and recreation domains: unmatched case-control study

BACKGROUND

Low-level physical activity (LLPA) is crucial for the well-being of adults living with HIV (PLWHs). However, many do not engage in enough physical activity, leading to adverse health outcomes. Identifying the determinants of LLPA can aid in developing effective interventions. Despite this, Ethiopia lacks evidence on this topic. This study aimed to identify predictors of LLPA among PLWHs in the Gedeo zone, located in southern Ethiopia.

METHODS

An unmatched case-control study was conducted on PLWHs in the Gedeo zone who visited two hospitals and healthcare institutions between December 29th, 2017 and January 22nd, 2019. Respondents were classified into three categories based on their total physical activity levels: high, moderate, and low. Cases were defined as those meeting the criteria for LLPA, while controls were those who did not fall under the cases category. Data was collected using the WHO Stepwise surveillance tool and analyzed using Epidata v3.1 templates and SPSS v22. Predictor variables with a P-value < 0.25 in bivariable analysis and < 0.05 with a 95% confidence interval in multivariable analysis were selected.

RESULTS

The study involved 633 HIV-positive adults, with a response rate of 92.41%. Most participants were under 34 years old, with an average age of 36.47±(9.055) for cases and 36.38±(8.389) for controls. The multivariable analysis revealed that educational status (AOR = 4.85, P = 0.02, 95%CI (1.28-18.44)), sex (AOR = 0.24, P = 0.04, 95%CI (0.07-0.90)), duration on ART being exposed for 1-4 Years (AOR = 0.12, P < 0.001, 95%CI (0.03-0.44)) and being exposed for 5-9 Years (AOR = 0.03, P < 0.001, 95%CI (0.01-0.16)), and former alcohol use (AOR = 0.11, P < 0.01, 95%CI (0.02-0.56) were significant predictors of LLPA performance.

CONCLUSIONS

The study concluded that educational status, sex, ART duration, and past alcohol use are key determinants of LLPA performance among PLWHs in southern Ethiopia. This suggests that policymakers should implement public health campaigns to promote healthy habits, particularly low-level physical activity, among PLWHs.

Trends and age-period-cohort effect on the incidence of falls from 1990 to 2019 in BRICS

Background

The increasing burden of falls in BRICS countries warrants a comprehensive investigation to understand the dynamics and trends. This study utilized data from the Global Burden of Disease Study (GBD) 2019 to assess fall incidence rates in Brazil, Russia, India, China, and South Africa (BRICS) to provide valuable insights for the development of targeted prevention and management strategies.

Methods

Data from the GBD 2019 were employed to estimate fall incidence rates. The study utilized age-period-cohort (APC) model analysis, implemented using R 4.3.0 software and the R package apc, to examine fall incidence trends from 1990 to 2019.

Results

In 2019, the BRICS nations collectively reported 32.32 million fall cases. The overall fall incidence rate increased from 2681.7 per 100,000 people in 1990-2896.3 per 100,000 people in 2019. China and India exhibited escalating trends, with China experiencing the highest growth rate at 21%, followed by India at 5.8%. South Africa displayed a comparatively lower overall incidence rate increase. Notably, the 90-94 age group in China exhibited the most significant deterioration, with men and women experiencing annual increases of 4.23% and 1.77%, respectively. Age effects indicated a higher susceptibility to falls among preschool children and the elderly. Period effects revealed no improvement in the fall state for India (2005-2019) and China (2015-2019). Cohort effects adversely impacted the incidence rate for individuals born earlier in South Africa.

Conclusion

The present study highlights a consistent upward trend in fall incidence rates across BRICS countries from 1990 to 2019. With an aging population, the burden of fall-related diseases is on the rise in these nations. Our results underscore the necessity of formulating evidence-based disease prevention and management approaches tailored to the distinctive demographic attributes of each nation. Addressing these trends is crucial for mitigating the growing impact of falls on public health in BRICS countries.

Level of physical activity and its associated factors among adults in southeast Ethiopia: a community-based cross-sectional study

OBJECTIVE

Insufficient levels of physical activity are a well-known modifiable risk factor for a number of chronic conditions including obesity, type 2 diabetes, cardiovascular diseases and certain malignancies. Little is known about the status of physical activity and its associated factors among adults in low-income countries, including Ethiopia. Therefore, this study aimed to assess the level of physical activity and its associated factors among adults in southeast Ethiopia.

DESIGN

Analytical cross-sectional study.

SETTING

Community setting in southeast Ethiopia.

PARTICIPANTS

641 adults aged 18-64 years.

PRIMARY OUTCOME

Level of physical activity assessed via the Global Physical Activity Questionnaire (GPAQ).

RESULTS

The overall prevalence of insufficient physical activity in this study was 29.48% (95% CI: 25.78 to 33.18). Women were more likely to report insufficient physical activity compared with men (39.0% for women and 12.3% for men, p<0.001). Being: a women (adjusted OR (AOR)=3.99, 95% CI: 2.15 to 7.40)), overweight/obese (AOR=1.95, 95% CI: 1.23 to 3.09), ever-married (AOR=2.13, 95% CI: 1.01 to 4.47), a person with no formal education (AOR=1.94, 95% CI: 1.05 to 3.56), a housewife (AOR=3.04, 95% CI: 1.75 to 5.29) and unemployed (AOR=3.30, 95% CI: 1.55 to 7.02) were significantly associated with insufficient physical activity.

CONCLUSION

The study revealed that three in 10 adults did not achieve the recommended level of physical activity. For chronic disease prevention in Ethiopia, the Ethiopian Ministry of Health and other stakeholders should pay special attention to strategies to improve the population's physical activity especially among women, housewives, people with no formal education, and married, unemployed and overweight/obese adults.

Physical Activity Policies for Children and Adolescents in Brazil: Analysis for the Report Card Brazil on Physical Activity for Children and Adolescents

The aim of this study was to investigate physical activity (PA) policies in Brazil through current actions/programs to promote PA for children and adolescents. All 23 official websites of federal government agencies in Brazil [eighteen ministries, two secretariats (linked to ministries) and three ministry equivalent agencies] were visited. All programs/actions were analyzed according to indicators of the Global Matrix project from the Active Healthy Kids Global Alliance (AHKGA) and the Health Enhancing PA Policy Audit Tool, version 2, recommended by the World Health Organization. Furthermore, we used the analysis of "Strengths, Weaknesses, Opportunities and Threats" (SWOT) for the policies. Seventeen programs/actions included the promotion of PA for children and adolescents in Brazil, however, none of them had this as their main objective, and none were planned as a public policy action aimed at the promotion of PA. The overall score of the assessment instrument was 37 (out of a total of 100), which classifies Brazil as having a D+ grade according to AHKGA criteria. Brazil needs to define PA as a state policy so that the actions identified in this study can have positive effects on children and adolescents.

A Critical Review on New Approaches for Chronic Disease Prevention in Brazil and Canada: From Wholistic Dietary Guidelines to Physical Activity Security

In light of new evidence on the prevention of chronic diseases and the elevated rates of overweight and obesity in Brazil and Canada, this critical review aims to interpret and synthesize current aspects regarding dietary and physical activity initiatives in both countries and make future recommendations. The pioneering work presented in the last Brazilian dietary guidelines has been called a model that can be applied globally, given its conceptualization of healthy eating that translates easily to practical guidance. The new Canadian Food Guide has incorporated similar aspects, also putting the country as a leader in dietary guidance. With these new recommendations, citizens in both Brazil and Canada have access to impactful evidence-informed nutritional guidelines. Both documents propose eating patterns that focus not only on health benefits, such as chronic disease prevention, but also incorporate well-being concerning cultural, economic, sociodemographic, biological, and ecological dimensions. A similar approach is required for physical activity to allow individuals to have attainable health and life goals and thereby fully enjoy their lives, regardless of geographical location, health status, and socioeconomic condition, a concept recently described as physical activity security. The wholistic dietary guidelines from both countries represent a change in paradigm in public health. Likewise, national evidence-based policies are warranted to reduce disparities in physical activity, allowing healthier and more active lifestyles for everyone.
