The Influence of Lifestyle Factors on the Prevention of Non-Communicable Diseases among Adolescents

Abstract

Background: Non-communicable diseases (NCDs), such as heart disease, diabetes and obesity, are rapidly rising in adolescence due to poor lifestyle choices, including unhealthy diets, lack of physical activity, poor sleep and alcohol and tobacco use. The prevention of NCDs in adolescence is essential for minimising future health effects. Objective: This research will explore the role of lifestyle factors in preventing NCDs in adolescents and assess how healthy lifestyle choices mitigate risk factors. Methodology: We conducted a secondary data systematic review of peer-reviewed articles, global health reports and epidemiological studies on the prevention of NCDs among adolescents published between 2015 and 2024. Research focusing on the 10-19 year age group and associations between lifestyle factors and NCDs was selected. Findings: The study suggests adolescents who consistently engaged in physical activity (≥60 minutes per day) had a 25-30% reduced risk for obesity and cardiovascular disease. Consumption of a healthy diet with fruit and vegetables was linked to 20% lower metabolic complications, with better health outcomes (close to 15%) linked to adequate sleep durations (8-10 hours per night). On the other hand, sedentary lifestyles and drug use were associated with a high risk of NCDs. Conclusion: Lifestyle modifications during adolescence play a vital role in preventing NCDs. Promoting healthy behaviors through education, policy, and community interventions can substantially reduce disease burden in later life.
