Analysis of the spatial distribution and comparison of the levels of radiofrequency pollution in Sri Lanka's two most populous cities.

In the twenty-first century, wireless communication tools have become indispensable in our daily lives, particularly during a pandemic, playing a crucial role. However, it is important to recognize that prolonged and excessive exposure to radiofrequency (RF) waves, which serve as carriers for these wireless communication systems, can have detrimental health effects. The aim of this study is to assess the spatial distribution and compare the levels of RF radiation emitted by the GSM900, GSM1800, UMTS, LTE2.6, and WLan2.4 frequency bands in the cities of Colombo and Kandy in Sri Lanka. The plane wave power density values for each frequency band were measured at designated survey locations using a SPECTRAN HF6065 spectrum analyzer with an HL7060 directional antenna. A total of 31 survey points were selected in Kandy City, while Colombo City had 67 survey points covering various public locations. The findings reveal that Colombo City exhibits a higher concentration of scattered hotspots in the LTE2.6 frequency band, whereas Kandy City demonstrates a higher concentration in the GSM900 frequency band. Furthermore, comparing the average results, the RF radiation pollution in Colombo City is more than 50% higher than that in Kandy City. The measured maximum RF level was detected in Colombo City in the frequency band GSM1800, and it is only 0.11% of the maximum permitted level as established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Behavioral Health Issues of NC Farmers: What Can't be Fixed with Tape and Twine.

Pressures on North Carolina's agricultural community are at an unprecedented level. Known stressors are compounded by lawsuits, tariffs, and beliefs that others have a negative perception of agriculture. Individuals find themselves with an array of negative emotions precipitating stress, anxiety, depression, and increased risk of suicide without needed prevention.

A global reference for caesarean section rates (C-Model): a multicountry cross-sectional study.

OBJECTIVE: To generate a global reference for caesarean section (CS) rates at health facilities. DESIGN: Cross-sectional study. SETTING: Health facilities from 43 countries. POPULATION/SAMPLE: Thirty eight thousand three hundred and twenty-four women giving birth from 22 countries for model building and 10,045,875 women giving birth from 43 countries for model testing. METHODS: We hypothesised that mathematical models could determine the relationship between clinical-obstetric characteristics and CS. These models generated probabilities of CS that could be compared with the observed CS rates. We devised a three-step approach to generate the global benchmark of CS rates at health facilities: creation of a multi-country reference population, building mathematical models, and testing these models. MAIN OUTCOME MEASURES: Area under the ROC curves, diagnostic odds ratio, expected CS rate, observed CS rate. RESULTS: According to the different versions of the model, areas under the ROC curves suggested a good discriminatory capacity of C-Model, with summary estimates ranging from 0.832 to 0.844. The C-Model was able to generate expected CS rates adjusted for the case-mix of the obstetric population. We have also prepared an e-calculator to facilitate use of C-Model (www.who.int/reproductivehealth/publications/maternal_perinatal_health/c-model/en/). CONCLUSIONS: This article describes the development of a global reference for CS rates. Based on maternal characteristics, this tool was able to generate an individualised expected CS rate for health facilities or groups of health facilities. With C-Model, obstetric teams, health system managers, health facilities, health insurance companies, and governments can produce a customised reference CS rate for assessing use (and overuse) of CS. TWEETABLE ABSTRACT: The C-Model provides a customized benchmark for caesarean section rates in health facilities and systems.

Maternal death review in selected countries of South East Asia Region.

Understanding the underlying factors that led to maternal deaths through a maternal death review (MDR) throws light on the causes, characteristics and circumstances of the death. We reviewed and report on the implementation of MDR in India, Indonesia, Myanmar, Nepal and Sri Lanka, capturing the experiences of MDR initiatives, follow-up actions and lessons learnet. Overall, while the findings from MDRs have been used to design or change policies and strategies for improvement of services provided, there are still challenges in scaling up these initiatives, particularly in the larger countries.

Risk factors for spontaneous and provider-initiated preterm delivery in high and low Human Development Index countries: a secondary analysis of the World Health Organization Multicountry Survey on Maternal and Newborn Health.

OBJECTIVE: To evaluate how the effect of maternal complications on preterm birth varies between spontaneous and provider-initiated births, as well as among different countries. DESIGN: Secondary analysis of a cross-sectional study. SETTING: Twenty-nine countries participating in the World Health Organization Multicountry Survey on Maternal and Newborn Health. POPULATION: 299 878 singleton deliveries of live neonates or fresh stillbirths. METHODS: Countries were categorised into very high, high, medium and low developed countries using the Human Development Index (HDI) of 2012 by the World Bank. We described the prevalence and risk of maternal complications, their effect on outcomes and their variability by country development. MAIN OUTCOME MEASURES: Preterm birth, fresh stillbirth and early neonatal death. RESULTS: The proportion of provider-initiated births among preterm deliveries increased with development: 19% in low to 40% in very high HDI countries. Among preterm deliveries, the socially disadvantaged were less likely, and the medically high risk were more likely, to have a provider-initiated delivery. The effects of anaemia [adjusted odds ratio (AOR), 2.03; 95% confidence interval (CI), 1.84; 2.25], chronic hypertension (AOR, 2.28; 95% CI, 1.94; 2.68) and pre-eclampsia/eclampsia (AOR, 5.03; 95% CI, 4.72; 5.37) on preterm birth were similar among all four HDI subgroups. CONCLUSIONS: The provision of adequate obstetric care, including optimal timing for delivery in high-risk pregnancies, especially to the socially disadvantaged, could improve pregnancy outcomes. Avoiding preterm delivery in women when maternal complications, such as anaemia or hypertensive disorders, are present is important for countries at various stages of development, but may be more challenging to achieve.

Mode and timing of twin delivery and perinatal outcomes in low- and middle-income countries: a secondary analysis of the WHO Multicountry Survey on Maternal and Newborn Health.

OBJECTIVE: To describe the mode and timing of delivery of twin pregnancies at ≥34 weeks of gestation and their association with perinatal outcomes. DESIGN: Secondary analysis of a cross-sectional study. POPULATION: Twin deliveries at ≥34 weeks of gestation from 21 low- and middle-income countries participating in the WHO Multicountry Survey on Maternal and Newborn Health. METHODS: Descriptive analysis and effect estimates using multilevel logistic regression. MAIN OUTCOME MEASURES: Stillbirth, perinatal mortality, and neonatal near miss (use of selected life saving interventions at birth). RESULTS: The average length of gestation at delivery was 37.6 weeks. Of all twin deliveries, 16.8 and 17.6% were delivered by caesarean section before and after the onset of labour, respectively. Prelabour caesarean delivery was associated with older maternal age, higher institutional capacity and wealth of the country. Compared with spontaneous vaginal delivery, lower risks of neonatal near miss (adjusted odds ratio, aOR, 0.63; 95% confidence interval, 95% CI, 0.44-0.94) were found among prelabour caesarean deliveries. A lower risk of early neonatal mortality (aOR 0.12; 95% CI 0.02-0.56) was also observed among prelabour caesarean deliveries with nonvertex presentation of the first twin. The week of gestation with the lowest rate of prospective fetal death varied by fetal presentation: 37 weeks for vertex-vertex; 39 weeks for vertex-nonvertex; and 38 weeks for a nonvertex first twin. CONCLUSIONS: The prelabour caesarean delivery rate among twins varied largely between countries, probably as a result of overuse of caesarean delivery in wealthier countries and limited access to caesarean delivery in low-income countries. Prelabour delivery may be beneficial when the first twin is nonvertex. International guidelines for optimal twin delivery methods are needed.

Effects of a behavior-based weight management program delivered through a state cooperative extension and local public health department network, North Carolina, 2008-2009.

INTRODUCTION: Eat Smart, Move More, Weigh Less (ESMMWL) is an adult weight management program developed in response to North Carolina Obesity Plan recommendations to make weight management interventions accessible to underserved populations. ESMMWL was designed to be delivered through the North Carolina Cooperative Extension and North Carolina Division of Public Health. Program coursework included content on evidence-based eating and physical activity behaviors and incorporated mindful eating concepts. The objectives of this study were to describe participant changes in weight and behaviors and to document the effectiveness of the program. METHODS: In this prospective pilot study, courses were delivered and data collected from January 2008 through June 2009. Instructors provided feedback about implementation. For participants, height, weight, and waist circumference were measured at baseline and completion. Participants completed a questionnaire about changes in their eating and physical activity behaviors, changes in their confidence to engage in weight management behaviors, and their satisfaction with the course. RESULTS: Seventy-nine instructors delivered 101 ESMMWL courses in 48 North Carolina counties. Most of the 1,162 completers were white women. Approximately 83% reported moving toward or attaining their goal. The average weight loss was 8.4 lb. Approximately 92% reported an increase in confidence to eat healthfully, and 82% reported an increase in confidence to be physically active. Instructors made suggestions for program standardization. CONCLUSION: This study demonstrated the effectiveness, diffusion, and implementation of a theoretically based weight management program through a state extension and local public health department network. Study of the sustainability of changes in eating and physical activity behaviors is needed.

Evaluation capacity building in the nonformal education context: Challenges and strategies.

Policymakers' demand for increased accountability has compelled organizations to pay more attention to internal evaluation capacity building (ECB). The existing literature about ECB has focused on capacity building experiences and organizational research, with limited attention on challenges that internal evaluation specialists face in building organizational evaluative capacity. To address this knowledge gap, we conducted a Delphi study with evaluation specialists in the United States' Cooperative Extension Service and developed a consensus on the most pervasive ECB challenges as well as the most useful strategies for overcoming ECB challenges. Challenges identified in this study include limited time and resources, limited understanding of the value of evaluation, evaluation considered as an afterthought, and limited support and buy-in from administrators. Alternatively, strategies found in the study include a shift in an organizational culture where evaluation is appreciated, buy-in and support from administration, clarifying the importance of quality than quantity of evaluations, and a strategic approach to ECB. The challenges identified in this study have persisted for decades, meaning administrators must understand the persistence of these issues and make an earnest investment (financial and human resource) to make noticeable progress. The Delphi approach can be used more often to prioritize ECB efforts.

Expanding evaluator competency research: Exploring competencies for program evaluation using the context of non-formal education.

The overlap of competencies between general program evaluation and specific contexts or content will always be reality because evaluators may need unique competencies to answer evaluation questions for particular contexts or content areas. Limited research exists that explores the essential competencies required by professionals who use evaluation as one part of their job portfolio, which leaves unanswered questions regarding the applicability of current evaluator competency models in such settings. We used a modified three-round Delphi technique to identify evaluator competencies for non-formal educators in Cooperative Extension (CE). Our panelists identified 36 competencies in the non-formal educational programming context for CE educators that they considered important to be included in evaluation capacity building efforts. We categorized our 36 identified competencies from the Delphi study into the five competency domains proposed by the American Evaluation Association. Our findings provide information to help guide professional development among non-formal educators related to program evaluation.

Use of song as an effective teaching strategy for nutrition education in older adults.

The objective of this study was to explore whether singing an educational song would be effective in improving older adults' knowledge about nutrition. We used a randomized controlled design to determine whether singing an educational song would result in increased nutrition knowledge in a low-income population of older adults compared to a control group of similar adults who did not sing the song. Eighteen congregate nutrition sites were randomly assigned to the treatment or control group. Analysis via independent samples t -test showed the knowledge gain mean scores for the treatment group were significantly ( P  < 0.05) greater than those of the control group. This study supports a unique new approach to increasing nutrition knowledge of older adults by using music.

Using synchronous distance-education technology to deliver a weight management intervention.

OBJECTIVE: To compare the effectiveness of online delivery of a weight management program using synchronous (real-time), distance-education technology to in-person delivery. METHODS: Synchronous, distance-education technology was used to conduct weekly sessions for participants with a live instructor. Program effectiveness was indicated by changes in weight, body mass index (BMI), waist circumference, and confidence in ability to eat healthy and be physically active. RESULTS: Online class participants (n = 398) had significantly greater reductions in BMI, weight, and waist circumference than in-person class participants (n = 1,313). Physical activity confidence increased more for in-person than online class participants. There was no difference for healthy eating confidence. CONCLUSIONS AND IMPLICATIONS: This project demonstrates the feasibility of using synchronous distance-education technology to deliver a weight management program. Synchronous online delivery could be employed with no loss to improvements in BMI, weight, and waist circumference.

Delivering a behavior-change weight management program to teachers and state employees in North Carolina.

PURPOSE: To ascertain the effectiveness of a behavior-change weight management program offered to teachers and state employees in North Carolina (NC). DESIGN: Fifteen-week weight management program with premeasures and postmeasures. SETTING: State agencies and public K-12 schools in five NC counties. SUBJECTS: A total of 2574 NC state employees enrolled in 141 classes. INTERVENTION: Eat Smart, Move More, Weigh Less (ESMMWL) is a 15-week weight management program delivered by trained instructors. Lessons inform, empower, and motivate participants to live mindfully as they make choices about eating and physical activity. MEASURES: Height, weight, body mass index (BMI), waist circumference, blood pressure, confidence in ability to eat healthy and be physically active, changes in eating, and physical activity behaviors. ANALYSIS: Descriptive statistics, t-tests, χ(2) tests, and analyses of variance. RESULTS: Data are reported for 1341 participants in ESMMWL who completed the program, submitted an evaluation, and had not participated in the program in the past; 89% were female and mean age was 48.8 years. Average BMI and waist circumference decreased significantly. Confidence in eating healthfully and being physically active increased significantly. The percentage of participants with a BMI < 30 kg/m(2) increased from 40% to 45% and those with a normal blood pressure increased from 23% to 32.5%. Participants reported being more mindful of what and how much they ate (92%), being more mindful of how much daily physical activity they got (88%), and eating fewer calories (87.3%). CONCLUSION: This project demonstrated the feasibility of implementing a behavior change-based weight management program at the worksite to achieve positive outcomes related to weight, blood pressure, healthy eating, and physical activity behaviors. Programs such as this have the potential to provide health care cost savings.
