Summary
Low physical activity is an independent risk factor for newly-diagnosed hypertension in Taiwan. This study highlights the importance of regular exercise in preventing high blood pressure among adults.
Area of Science:
- Cardiovascular Health
- Public Health
- Epidemiology
Background:
- Hypertension prevalence and its associated risk factors are critical public health concerns.
- Understanding the link between lifestyle factors, such as physical activity, and hypertension is essential for targeted interventions.
- Previous research indicates a correlation between physical activity and cardiovascular health, but specific data on newly-diagnosed hypertension in Taiwan is needed.
Purpose of the Study:
- To investigate the prevalence of hypertension in Nanhwa Township, Taiwan.
- To identify risk factors associated with newly-diagnosed hypertension.
- To examine the association between reported physical activity levels and the incidence of hypertension.
Main Methods:
- A cross-sectional study involving 479 participants (aged over 20) randomly sampled from Nanhwa Township, Tainan County, Taiwan.
- Data collection included questionnaire interviews, blood pressure measurements, and anthropometric assessments.
- Statistical analyses, including multiple logistic regression, were used to identify independent risk factors, adjusting for age, sex, BMI, waist-to-hip ratio, and family history.
Main Results:
- The age-sex-standardized prevalence of hypertension was 17.8% (JNC V criteria) and 11.3% (WHO criteria) for adults over 20.
- Factors correlated with hypertension included education level, socioeconomic status, history of heart disease/diabetes, family history, BMI, waist-to-hip ratio, and physical activity level.
- Low physical activity, particularly low sports activity, emerged as an independent risk factor for hypertension.
Conclusions:
- Physical activity level is a significant independent risk factor for hypertension in the studied Taiwanese population.
- Public health initiatives should promote physical activity to mitigate the risk of developing hypertension.
- Further research can explore specific types and intensities of physical activity most beneficial for hypertension prevention.
