Globally, overweight and obesity among children have been acknowledged as a growing public health concern. In sub-Saharan Africa, the prevalence of overweight and obesity is high. In Uganda, there is a significant burden of overweight and obesity. This study was conducted to determine the prevalence and associated factors that influence overweight and obesity among primary school children in Southwestern Uganda. A cross-sectional study utilized a self-administered questionnaire and anthropometric tools to collect data. A three-stage sampling procedure was used to select four schools that participated in this study. A total of 422 children participated in our study. Participant’s weight and height were measured using SECA Scale, Model 885, and a wall-mounted stadiometer, respectively. Data were analyzed using STATA v11.0. The prevalence of overweight/obesity was descriptively analyzed. Associated factors were determined using bivariate and multivariate analysis. Findings revealed that 54.3% of participants were walking to school compared to 45.7% that were cycling/bicycling and 76.3% playing and doing household chores as opposed to 23.7% that spent their leisure time through reading and watching TV, 74.2% took more than two meals per day, and 79.4% often took vegetables and fruits compared to 20.6% that took them most of the time. The study found an overall prevalence of 20% for overweight/obesity. There was a statistical association between overweight/obesity and ownership of residence (O.R.: 0.4, 95% C.I.: 0.2–0.8), modes of transport (O.R.: 8.2, 95% C.I.: 3.4–20.0), leisure time activities (O.R.: 0.4, 95% C.I.: 0.2–0.7), frequency of consuming vegetables and fruits (O.R.: 2.8, 95% C.I.: 1.4–5.5), and the type of school attended (O.R.: 0.2, 95% C.I.: 0.1–0.4). However, only the mode of transport (A.O.R.: 5.0, 95% C.I.: 1.9–13.0) was independently associated with overweight/obesity on multivariate logistic regression analysis. Girls who participated in our study were more overweight than boys. Overweight/obesity existed more in private schools than public schools. Modes of transport were only found to be strongly associated with overweight/obesity. There is a need to establish evidence-based strategies to inform policy on prevention of childhood overweight/obesity.

South Africa is facing a high burden of COVID-19 pandemic with low-vaccine coverage in the African Region. We aimed to investigate the temporal changes and impacts in health behaviors on vaccine acceptability in pre-, during-, and post-vaccine roll-out periods. In this cross-sectional study, we used the combined data from the nationally conducted “COVID-19 Vaccine Surveys (CVACS)” (May 2020–February/March 2022). Semiparametric regression models were used to capture the nonlinear association between the vaccine acceptability and health behaviors. Our study provided compelling evidence for a substantial decline in COVID-19 vaccine trust which shifted from 62%–70% to 26%–42% overtime. Participants younger than 40 years of age were less likely to receive the vaccine before it became available. However, this association changed in the postvaccine period with significant uptake in vaccine acceptance in younger groups. South Africans who identified themselves as black were more likely to intend to receive (aORs ranged: 1.93−3.60) and to trust the vaccine’s safety and efficacy (aORs ranged:1.79−1.23) in all time periods. “Mask wearing” and “frequent hand washing” were the most commonly reported behaviors. Given the lower rates of vaccine acceptability and a reduction in preventative health behaviors, monitoring the spread of infections is crucial and may have significant clinical and epidemiological implications.

Background. It is necessary to monitor the health disorders of healthcare practitioners exposed to a complex of occupational hazards to optimize their activities and substantiation of preventive health measures. The purpose of the study was the hygienic assessment of occupational hazards, analysis of data on self-assessment of the state of health (SASH questionnaire) among healthcare practitioners (MRI diagnostics specialists, ultrasound diagnostics specialists, and ophthalmologists, as a control group) exposed to nonionizing radiation, ultrasound, and noise. Materials and Methods. An analysis of hygienic parameters of the working environment (workplace) and questionnaire data of healthcare practitioners were carried out. The number of illnesses and absences from work, the level of quality of life, the level of depression, and the self-assessment of the state of health were evaluated according to the questionnaire. Results. An analysis of workloads made it possible to rank the severity and intensity of labor. Health disorders (according to the self-assessment of the state of health), the number of absences from work due to illness, an increase in complaints and level of depression, and a decrease in the level of quality of life were corresponded to the severity of labor. It was revealed that healthcare practitioners were exposed to a number of hazards during their work (above the threshold limit value (TLV)), which caused an increase in health disorders. Conclusions. During the organization of workplace ergonomics and implementation of preventive measures directed to maintaining health and early diagnosis of diseases, one should take into account the hygienic indicators of the working environment that exceed TLV, the results of self-assessment of the state of health (complaints) and morbidity of healthcare practitioners, the level of quality of life and the level of depression.

Objective. This study evaluates the effectiveness of the “150 Minutes Program” in increasing awareness and fostering positive behavior changes regarding recommended physical activity guidelines among Saudi college students. Initiated as part of the national “Sports for All Challenge,” this program targets college students to improve their understanding of the U.S. Department of Health and Human Services’ physical activity guidelines. Methods. Engaging over 250 Saudi college students from 17 student groups across the United States, the program employs two intervention strategies: a general awareness campaign and the application of physical activity guidelines tailored to the Saudi student community. The study assesses the program’s impact through pre-/post-surveys, evaluating changes in participants’ awareness levels and physical activity behaviors. Results. A total of 110 participants completed either the presurvey (n = 35) or postsurvey (n = 75). Results indicate a significant rise in participants’ awareness of recommended physical activity guidelines, increasing from an initial 4% to 22.9%. Postprogram surveys reveal positive shifts in physical activity behaviors, with 51.4% of participants meeting adult physical activity guidelines, compared to 40% before the program. The average physical activity levels also demonstrated an increase. Conclusion. The 150 Minutes Program proves effective not only in enhancing awareness but also in instigating positive physical activity behavior changes among Saudi college students. The study contributes valuable insights to the evolving landscape of physical activity interventions within college populations, emphasizing the need for targeted programs, and collaborations with student organizations to ensure sustained impact and scalability.

Background. The Health Locus of Control (HLC) serves as a mediator between an individual’s behaviors and health status, influenced by various cultural, environmental, and situational factors. Its measurement reflects health beliefs and attitudes, ultimately leading to healthy behaviors. Menopause is a significant phenomenon in women’s lives, often resulting in a wide range of symptoms and health issues. Therefore, the perception of HLC plays a crucial role in promoting healthy behaviors and managing menopausal symptoms. This study aimed to assess the validity and reliability of the Persian version of the short form Multidimensional Health Locus of Control Scale (MHLC) in Iranian menopausal women and explore its interrelationships. Methods. A cross-sectional study was conducted with 271 menopausal women from September to November 2023. Psychometric properties such as construct validity (confirmed through confirmatory factor analysis), convergent validity (evaluated using average variance extracted), and internal consistency (assessed by Cronbach’s alpha, composite reliability and rho_A factor) were examined. Discriminant validity was determined using the Fornell–Larcker criterion. Reliability was further established through Cronbach’s alpha and McDonald’s Omega coefficients. The predictive relevance of the model and associations between constructs were analyzed using various statistical measures. Data analysis was conducted using SPSS v.27 and Smart PLS 3.0 software. Limitations of this study include that it was conducted in urban health centers, only women with at least primary education were included, and reliance on self-reported data. Results. The initial stage of construct validity involved the Kolmogorov–Smirnov test, with confirmatory factor analysis demonstrating a good model fit. Significant correlations were found between internal health control and factors related to doctors and other people, indicating that internal health control directly influences these factors in managing menopausal symptoms and health problems. Cronbach’s alpha and McDonald’s Omega coefficients for the 13-item MHLC-C scale were satisfactory (0.81 and 0.72, respectively). Conclusions. The Persian version of the 13-item MHLC-C has been validated as a reliable tool for assessing the health locus of control in Iranian menopausal women. Internal health control was found to significantly impact perceptions related to doctors and other people, highlighting its importance in managing menopausal symptoms effectively.

The COVID-19 pandemic has been a global pandemic and a threat to humankind. In addition to many cases of illness and millions of deaths, the economy and social interactions have suffered. It remarkably declined overall transportation and mobility in most countries. However, given that there is a gap between environmental sustainability awareness and what is practiced by transport users, the goal of this study was to empirically assess the mediating role of environmental awareness in the casual links between perceived risks of the COVID-19 pandemic and ecologically sustainable transportation use. The study identified relevant theories, conceptual frameworks, and variables. Mixed research and surveys were carried out on the public and private transport service users in Addis Ababa, Ethiopia. Comparative analysis, structural equation modeling, and structural causal model framework were applied to estimate casual relationships among variables and test the hypotheses. Despite the rising of human-caused climate change denial beliefs, findings revealed that a large part of the causes of the COVID-19 pandemic are climate change, biodiversity misuse, and wildlife degradation, all of which are environmental in nature and anthropogenic. People perceived the COVID-19 pandemic as more of a risk to others than to themselves, and climate change or global warming has become a danger to humanity, mainly during the pandemic. Accordingly, the pandemic risks increased people’s mainly passengers’ awareness of the environment, and this caused them to give greater consideration to the environmentally attractiveness of the transport they use. This, in turn, encouraged people to take personal climate-friendly measures and pro-environmental behavior, mainly greater willingness to use public transportation than private transportation during the COVID-19 pandemic than before. Thus, the total effect of the COVID-19 pandemic anxiety on the use of public transportation is completely mediated by enhanced environmental awareness. These are evidence that COVID-19 has strengthened environmental awareness and promoted sustainable action in the context of the transportation industry of developing countries. The study informs that urban planning and policy need to consider pandemic-sensitive and innovative public health and transport systems, integrated public health education, one health approach, and smart city. It suggests that maintaining the environmental awareness of societies and encouraging them to mitigate climate change through urgent climate actions and modal shifts to the use of sustainable urban transport such as public transportation.
