Background of the Study
Noise pollution has been recognized as a growing environmental health issue, particularly in urban areas with high levels of industrialization, traffic congestion, and commercial activities (WHO, 2024). Research has linked prolonged exposure to high noise levels with various health complications, including stress, sleep disturbances, and cardiovascular diseases such as hypertension (Adepoju & Yusuf, 2023).
Hypertension, or high blood pressure, is a major risk factor for stroke, heart failure, and kidney diseases. In Nigeria, hypertension prevalence has been increasing, with urban areas experiencing higher rates due to lifestyle changes, environmental stressors, and limited access to healthcare (Bello & Olatunji, 2024). Sokoto State, known for its growing commercial activities and traffic congestion, is experiencing rising noise pollution levels that may be contributing to hypertension cases among its residents (Ogunyemi et al., 2024).
This study seeks to assess the statistical association between noise pollution and hypertension in Sokoto State, analyzing data on noise exposure levels and hypertension prevalence to determine whether environmental noise contributes significantly to cardiovascular health risks.
Statement of the Problem
Hypertension has become a leading public health challenge in Sokoto State, yet many of its environmental determinants remain understudied. While lifestyle factors such as diet and physical activity are well-documented contributors, the potential role of noise pollution in elevating blood pressure levels has not been thoroughly examined in this region (Adepoju et al., 2024).
Given the increasing urbanization of Sokoto State, residents are frequently exposed to high noise levels from traffic, markets, industrial zones, and public events. However, there is limited statistical evidence assessing whether chronic noise exposure is directly associated with hypertension in Sokoto State (Bello & Olatunji, 2024).
This study will fill this research gap by conducting a statistical analysis of the relationship between noise pollution and hypertension in Sokoto State, providing data to support policy recommendations for noise regulation and cardiovascular disease prevention.
Objectives of the Study
1. To determine the prevalence of hypertension among residents of Sokoto State.
2. To analyze the statistical association between noise pollution exposure and hypertension prevalence.
3. To evaluate potential interventions to mitigate the impact of noise pollution on cardiovascular health.
Research Questions
1. What is the prevalence of hypertension in Sokoto State?
2. How does noise pollution influence hypertension prevalence among residents?
3. What interventions can be implemented to reduce the impact of noise pollution on cardiovascular health?
Research Hypotheses
1. There is a significant positive correlation between noise pollution exposure and hypertension prevalence in Sokoto State.
2. Individuals living in high-noise environments have a higher risk of developing hypertension compared to those in low-noise areas.
3. Public health interventions aimed at reducing noise pollution can significantly lower hypertension rates.
Scope and Limitations of the Study
This study will focus on the relationship between noise pollution and hypertension in Sokoto State, analyzing environmental noise data, health records, and population surveys. Data will be collected from both urban and rural areas to assess variations in exposure and health outcomes.
Limitations may include difficulty in accurately measuring individual noise exposure levels, potential confounding factors such as diet and genetics, and incomplete hypertension diagnosis records.
