AI Article Synopsis
- Poor urban communities in Johannesburg, South Africa, will face significant health risks due to climate change, with predicted increases in temperature of up to 4°C by 2100.
- The study collected data from 136 households and 580 individuals to identify socio-economic and health risk factors associated with heat-related health effects, focusing on schoolchildren's parents.
- Common heat-related symptoms included sweating, headaches, and fatigue, with higher risks observed in individuals over 60 and those with pre-existing conditions like hypertension, highlighting the need for targeted awareness campaigns and better housing solutions.
Article Abstract
Introduction: Poor urban communities are likely to bear the brunt of climate change impacts on health and well-being. The City of Johannesburg, South Africa, is predicted to experience an average increase in ambient temperature of 4°C by 2100. Focusing on the urban environment, this study aimed to determine socio-economic, infrastructural and health-related risk factors for heat-related adverse health effects.
Methods: This was a cross-sectional study. Data of interest were collected using a pretested and validated questionnaire administered to parents of children attending schools participating in a school heat study. Information related to demographic, socio-economic and household-level determinants of health, which has an impact on the individual prevalence of adverse heat-health effects associated with hot weather, was collected for 136 households and 580 individuals.
Results: Sweating (n = 208 individuals; 35%), headache and nausea (n = 111; 19%) and weakness, fatigue and dizziness (n = 87; 15%) were the most common heat-health effects reportedly experienced by individuals (n = 580) during hot weather. Individuals who suffered from hypertension (OR = 2.32, 95% CI: 1.34 - 4.05, p = 0.003) and individuals older than 60 years (OR = 1.81, 95% CI: 1.27-1.99, p < 0.001) compared to other age groups were more likely to experience 'any heat-health effects'. Living in government-sponsored detached housing and in houses with asbestos roofs were associated with an increase in reported experience of 'any heat-health effects' compared to living in other housing types.
Conclusion: Heat-health awareness campaigns should target people suffering from pre-existing diseases and the elderly, as these groups are especially vulnerable to heat. Focus should also be given to appropriate roofing and insulation in government-sponsored housing since summertime temperatures are projected to increase.

Suitable temperature indicator for adverse health impacts in sub-tropical cities: a case study in Hong Kong from 2010-2019.

Heat-health warning systems and services are important preventive actions for extreme heat, however, global evidence differs on which temperature indicator is more informative for heat-health outcomes. We comprehensively assessed temperature predictors on their summer associations with adverse health impacts in a high-density subtropical city. Maximum, mean, and minimum temperatures were examined on their associations with non-cancer mortality and hospital admissions in Hong Kong during summer seasons 2010-2019 using Generalized Additive Models and Distributed Lag Non-linear Models.

Global warming, driven by increased greenhouse gas emissions, has led to unprecedented extreme weather events, contributing to higher morbidity and mortality rates from a variety of health conditions, including cardiovascular disease (CVD). The disruption of multiple planetary boundaries has increased the probability of connected, cascading, and catastrophic disasters with magnified health impacts on vulnerable populations. While the impact of climate change can be manifold, non-optimal air temperatures (NOTs) pose significant health risks from cardiovascular events.

Article Synopsis
- Global temperature rise is a significant health issue, and previous research mainly relied on hospital data to assess its effects on health.
- This study focused on the relationship between ambient temperature and various heat-related medical conditions using data from general practitioners in Flanders, Belgium, collected over eight years (2012-2019).
- The results indicated a J-shaped association between heat and health outcomes, with higher risks for certain conditions like skin problems and urinary infections at elevated temperatures, particularly at minimum temperature thresholds.

Background: Swiss climate scenarios predict increases in the frequency and intensity of extreme heat episodes in the future. For the effective prevention of heat-related mortality, several aspects of the population's vulnerability to heat must be understood on a local level.
Methods: A nationwide analysis of individual death records was conducted, enabling a more comprehensive understanding than typical heat studies based on aggregated data.

Article Synopsis
- A study was conducted to explore the effects of extreme heat stress on pregnant subsistence farmers in West Kiang, The Gambia, addressing a gap in research for at-risk populations.
- The study utilized both historical climate data and on-site measurements from 92 women to analyze the relationship between physiological responses (like skin temperature) and environmental factors, revealing stronger effects during the third trimester and heightened risks with higher humidity levels.
- It is recommended that local health systems adopt heat stress indices, such as UTCI or WBGT, to better inform and protect pregnant women from heat-related health issues.
