Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sustainable Prevention Program

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.

Group Type EXPERIMENTAL

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

Intervention Type OTHER

The SHiP-AEW is a 4-week multifaceted intervention program focused on evidence-based heat strain prevention strategies for agricultural workers over 60 years old. Delivered through weekly 1-hour sessions, the program incorporates the following primary components:

Control

Participants will receive no intervention and follow their usual workplace heat strain prevention measures such as basic hydration and voluntary rest breaks

Group Type NO_INTERVENTION

No interventions assigned to this group
