Association between active commuting and elevated blood pressure in adolescents

Area of Science:

• Public Health
• Epidemiology
• Adolescent Health

Background:

• High blood pressure (hypertension) is a growing concern in adolescent populations worldwide.
• Understanding modifiable lifestyle factors, such as commuting habits, is crucial for prevention strategies.

Purpose of the Study:

• To investigate the relationship between active commuting and the prevalence of high blood pressure among adolescents.
• To determine if this association differs between rural and urban settings.

Main Methods:

• Cross-sectional study involving 6039 adolescents (14-19 years) in Pernambuco, Brazil.
• Data collected via questionnaire on commuting habits and measured blood pressure.
• Logistic regression analysis adjusted for confounders like age, sex, and physical activity.

Main Results:

• Prevalence of high blood pressure was 7.3%; 79.3% of students had insufficient active commuting.
• Active commuting was significantly associated with lower high blood pressure risk only in rural adolescents (OR = 6.498).
• No significant association was found between active commuting and high blood pressure in urban adolescents (OR = 1.113).

Conclusions:

• Active commuting may serve as a protective factor against high blood pressure in rural adolescents.
• The findings suggest a potential environmental or social influence on the commuting-hypertension link.
• Further research is warranted to explore these geographical differences in urban and rural settings.
