Hubungan Kebiasaan Konsumsi Junk Food dengan Status Gizi dan Massa Lemak Tubuh pada Mahasiswa Fakultas Kedokteran Universitas Muhammadiyah Surabaya

Kebiasaan konsumsi junk food pada kelompok dewasa muda, khususnya mahasiswa, terus meningkat seiring perubahan gaya hidup modern. Pola konsumsi tersebut berpotensi memengaruhi status gizi dan meningkatkan akumulasi massa lemak tubuh sehingga meningkatkan risiko berbagai penyakit metabolik. Tujuan penelitian ini adalah menganalisis hubungan kebiasaan konsumsi junk food dengan status gizi dan massa lemak tubuh pada mahasiswi Fakultas Kedokteran Universitas Muhammadiyah Surabaya. Penelitian ini menggunakan desain observasional analitik dengan pendekatan cross-sectional. Teknik pengambilan sampel menggunakan total sampling, sehingga diperoleh 60 mahasiswi yang memenuhi kriteria inklusi dan eksklusi. Kebiasaan konsumsi junk food diukur menggunakan Food Frequency Questionnaire (FFQ), status gizi dinilai berdasarkan Indeks Massa Tubuh (IMT), sedangkan massa lemak tubuh diukur menggunakan Bioelectrical Impedance Analysis (BIA) InBody 570. Analisis data meliputi analisis univariat dan bivariat menggunakan uji Chi-Square dengan tingkat kemaknaan p<0,05. Hasil penelitian menunjukkan bahwa 31 responden (51,7%) memiliki kebiasaan konsumsi junk food kategori sering. Status gizi terbanyak adalah overweight sebanyak 18 responden (30,0%), sedangkan 41 responden (68,3%) memiliki massa lemak tubuh kategori overfat. Analisis bivariat menunjukkan terdapat hubungan yang bermakna antara kebiasaan konsumsi junk food dengan status gizi (p<0,001) serta massa lemak tubuh (p<0,001). Disimpulkan bahwa kebiasaan konsumsi junk food berhubungan secara signifikan dengan status gizi dan massa lemak tubuh pada mahasiswi Fakultas Kedokteran Universitas Muhammadiyah Surabaya. Upaya edukasi mengenai pola makan sehat dan pembatasan konsumsi junk food perlu ditingkatkan sebagai langkah pencegahan masalah gizi pada mahasiswa.

The consumption of junk food among young adults, particularly university students, has continued to increase due to changes in modern lifestyles. Such dietary habits may adversely affect nutritional status and promote excessive body fat accumulation, thereby increasing the risk of various metabolic diseases. This study aimed to analyze the relationship between junk food consumption habits and nutritional status as well as body fat mass among female students of the Faculty of Medicine, Universitas Muhammadiyah Surabaya. This study employed an analytical observational design with a cross-sectional approach. A total sampling technique was applied, resulting in 60 female students who met the inclusion and exclusion criteria. Junk food consumption habits were assessed using a Food Frequency Questionnaire (FFQ), nutritional status was determined based on Body Mass Index (BMI), and body fat mass was measured using the InBody 570 Bioelectrical Impedance Analysis (BIA). Data were analyzed using univariate and bivariate analyses, with the Chi-square test performed at a significance level of p<0.05. The results showed that 31 respondents (51.7%) had frequent junk food consumption habits. The most common nutritional status was overweight, accounting for 18 respondents (30.0%), while 41 respondents (68.3%) were classified as having overfat body fat levels. Bivariate analysis demonstrated a significant relationship between junk food consumption habits and nutritional status (p<0.001), as well as body fat mass (p<0.001). In conclusion, junk food consumption habits were significantly associated with nutritional status and body fat mass among female students of the Faculty of Medicine, Universitas Muhammadiyah Surabaya. Health education programs promoting healthy dietary habits and reducing junk food consumption should be strengthened to prevent nutritional problems among university students.
