Hubungan Pola Konsumsi Junk-Food dengan Perilaku Beresiko Penyakit Tidak Menular Pada Remaja SMP Terpadu Al-Farabi

Abstract

Junk food is generally high in calories, sugar, salt, and fat but low in fiber, vitamins, and minerals. Excessive junk food consumption among adolescents is a risk factor for the increasing incidence of non-communicable diseases (NCDs), such as obesity, hypertension, diabetes mellitus, and cardiovascular disease. Adolescence is a crucial period in the formation of eating habits that will influence health status in adulthood. Lifestyle changes, technological developments, and exposure to fast food advertisements on social media also influence adolescents' consumption behavior.This study aims to determine the relationship between junk food consumption patterns and risk behaviors for non-communicable diseases among students at Alfarabi Integrated Junior High School. The study used a descriptive quantitative approach with a cross-sectional design. Data collection was conducted on May 23, 2026, by distributing questionnaires directly to 34 ninth-grade students after receiving education about junk food and its impact on health. The results showed that 38.2% of respondents consumed junk food 1–2 times per week, 38.2% consumed it 3–5 times per week, and 23.5% consumed junk food every day. The most commonly consumed types of junk food were fast food (41.2%), instant noodles (32.4%), and sugary drinks (17.6%). Most respondents (70.6%) only exercised occasionally. Frequent health complaints included fatigue, acne, and weight gain. This study shows that high junk food consumption combined with low physical activity can be a risky behavior that contributes to increased risk factors for non-communicable diseases in adolescents. Therefore, education and the promotion of healthy lifestyle habits from school age are necessary.
