Hubungan dukungan teman sebaya remaja akhir terhadap motivasi latihan fisik pada mahasiswa: Analisis perbandingan berdasarkan status berat badan = The Relationship Between Peer Support in Late Adolescence and Exercise Motivation Among University Students: A Comparative Analysis Based on Weight Status.

Latihan fisik berperan penting dalam pencegahan penyakit tidak menular, namun partisipasinya pada remaja akhir dan mahasiswa masih rendah. Motivasi merupakan determinan utama perilaku latihan fisik, dan dukungan teman sebaya diduga berperan berbeda berdasarkan status berat badan. Penelitian ini bertujuan menganalisis perbedaan hubungan dukungan teman sebaya terhadap motivasi latihan fisik pada mahasiswa remaja akhir berdasarkan status berat badan. Desain penelitian berupa analitik observasional dengan desain potong lintang menggunakan data pemeriksaan kesehatan mahasiswa baru Universitas Indonesia tahun ajaran 2025–2026. Sebanyak 304 subjek dibagi menjadi kelompok berat badan normal/kurang (NR) dan berat badan berlebih/obesitas (OB). Data dikumpulkan menggunakan kuesioner terstandar untuk menilai motivasi latihan fisik, dukungan sosial, dan faktor internal, kemudian dianalisis secara univariat, bivariat, dan multivariat regresi linear. Skor motivasi latihan fisik lebih tinggi pada kelompok NR dibandingkan OB. Dukungan teman sebaya tidak berhubungan signifikan dengan motivasi latihan fisik pada kedua kelompok. Faktor internal berupa persepsi manfaat dan persepsi hambatan berhubungan signifikan dengan motivasi latihan fisik pada kedua kelompok, sedangkan efikasi diri hanya berhubungan signifikan pada kelompok NR. Dari hasil tersebut, motivasi latihan fisik mahasiswa lebih dipengaruhi oleh faktor internal dibandingkan dukungan teman sebaya, dengan pola hubungan yang berbeda berdasarkan status berat badan.

Physical exercise plays an important role in the prevention of non-communicable diseases; however, participation among late adolescents and university students remains low. Motivation is a key determinant of exercise behavior, and peer support is hypothesized to have different roles depending on weight status. This study aimed to analyze differences in the relationship between peer support and exercise motivation among late-adolescent university students based on weight status. This study employed an analytical observational design with a cross-sectional approach using health examination data of first-year students at Universitas Indonesia in the 2025–2026 academic year. A total of 304 participants were divided into normal/underweight (NR) and overweight/obese (OB) groups. Data were collected using standardized questionnaires to assess exercise motivation, social support, and internal factors, and were analyzed using univariate, bivariate, and multivariate linear regression analyses. Exercise motivation scores were higher in the NR group than in the OB group. Peer support was not significantly associated with exercise motivation in either group. Internal factors, namely perceived benefits and perceived barriers, were significantly associated with exercise motivation in both groups, whereas self-efficacy was significantly associated only in the NR group. These findings indicate that exercise motivation among university students is more strongly influenced by internal factors than by peer support, with different patterns observed according to weight status.
