Interventions: Other: Sustainable Heat Strain Prevention Program for Agricultural Elderly Workers (SHiP-AEW)

Brief Summary: The study explores a multi-component heat strain prevention program for older agricultural workers in response to climate change. It assesses hydration, rest breaks, reflective clothing, and shade provision. Utilizing a quasi-experimental design, it targets 120 elderly workers, evaluating core temperature, heart rate, and heat strain symptoms. The goal is to establish the program's effectiveness in safeguarding worker health and safety amidst increasing temperatures, offering evidence-based recommendations for this vulnerable group and potentially other occupations affected by climate change.

Detailed Description: This intervention study is designed to assess the efficacy of a sustainable heat strain prevention program tailored for elderly agricultural workers. It targets a specific population of 120 workers aged 60 years and above from Manial Shiha village. The study utilizes a quasi-experimental pretest-posttest design, dividing participants into intervention and control groups.

The core of the study involves a 4-week Sustainable Prevention Program, emphasizing practical and adoptable strategies like adequate hydration, regular rest breaks, the use of lightweight reflective clothing, and the provision of portable shade covers. This program is delivered through interactive methods including lectures, demonstrations, and group discussions, supplemented with educational materials.

Physiological responses to the program will be rigorously measured, employing core temperature sensors and heart rate monitors to provide objective data on the physical impact of the interventions. These measures, along with self-reported symptoms and heat strain levels collected through structured questionnaires, form the basis for a comprehensive evaluation of the program's effectiveness.

The study aims to provide a quantifiable reduction in heat strain indicators, offering insights into the program's potential for broader application in similar vulnerable populations

Arm && Interventions

Group	Intervention	Description
Sustainable Prevention Program	Sustainable Heat Strain Prevention Program for Agricultural Elderly Workers (SHiP-AEW)	Participants will receive the 4-week Sustainable Prevention Program consisting of lectures, demonstrations, group discussions, and educational materials focused on: Hydration strategies (proper amounts and types of fluids, reminders for intake) Rest breaks (frequency, duration, scheduling) Lightweight reflective clothing Device: Core Temperature Sensor Participants might be equipped with a core temperature sensor to monitor their internal body temperatures. This device will provide continuous, real-time data crucial for understanding the physiological impacts of the prevention strategies and ensuring participant safety. Device: Heart Rate Monitor A heart rate monitor will be used to track the cardiovascular responses of the participants to heat and physical activity. This data is essential to assess the strain on participants' bodies and the effectiveness of the prevention strategies in mitigating stress. Portable shade covers

Primary Outcome Measures

Name	Time	Method
Change in heat strain score from baseline to post-intervention	Baseline heat strain scores will be calculated from questionnaires completed 1 week prior to launching the program Post-intervention heat strain scores will be calculated from questionnaires completed within 1 week after finishing the 4-week program	The heat strain score is calculated from participant questionnaires assessing environmental conditions, workload, access to shade, and individual heat tolerance symptoms. Scores range from 0-30, with higher scores indicating greater levels of heat strain. Heat strain levels are categorized as low/no strain (score \<13.5), potential risk (13.6-18), or high risk (\>18). The primary outcome measure will evaluate the change in heat strain score from baseline (before starting the Sustainable Prevention Program) to post-intervention (after completing the 4-week program).
